The cutting apparatus according to the present embodiment, for cutting an object 11 to be cut, includes: a supporting seat 301, a pressing part 302, a lifting driving device 400 and a cutting part 100. Wherein the supporting base 301 supports the object 11 to be cut. The pressing portion 302 is provided above the support base 301, and presses the cut object 11. The lifting drive device 400 drives the support base 301 and the pressing portion 302 in the vertical direction so that the object 11 to be cut is driven in the vertical direction. The cutting unit 100 includes a main shaft 101 and a saw blade 102, and the saw blade 102 is attached to an outer periphery of the main shaft 101, rotates with rotation of the main shaft 101, and cuts the object 11 while the object 11 is driven in the vertical direction. The saw blade 102 is detachable with respect to the main shaft 101 and is adjustable in the axial direction of the main shaft 101 in a relaxed state with respect to the main shaft 101.

According to the cutting device of the embodiment, the cutting device can adapt to different objects to be cut 11, and the universality is improved. Specifically, since the saw blade 102 of the cutting unit 100 is adjustable in the axial direction of the main shaft 101 in a state of being loose from the main shaft 101, when cutting different objects 11 to be cut, the position of the saw blade 102 in the axial direction can be adjusted according to the size of the objects 11 to be cut, so that the cutting unit 100 can be adapted to the different objects 11 to be cut, thereby improving the versatility of the cutting apparatus.

Specifically, the cutting apparatus according to the present embodiment includes a frame 700 (for convenience of illustration, only a part of the frame 700 is illustrated in the drawing), and the cutting unit 100 is fixed to the frame 700. The object 11 to be cut is driven in the up-down direction, so that the saw blade 102 of the cutting part 100 cuts the object 11 to be cut while the object 11 to be cut is driven in the up-down direction. Examples of the object 11 include a metal such as a cast product or a steel pipe. A supporting base 301 for supporting the object 11 to be cut and a pressing portion 302 for pressing the object 11 to be cut are installed on the elevation driving means 400. The object 11 is supported by the support base 301 and pressed by the pressing portion 302, and is driven by the elevation driving device 400 to be elevated upward and downward, and at the same time, the saw blade 102 provided near the elevation driving device 400 is driven to cut the object 11.

The saw blade 102, which is the cutting part 100 for cutting the work 11, may include one or more blades. Taking a casting as an example, for example, in the case that the sheet-like material 12 (material) is formed in both the front and rear directions of the pouring gate 13, two saw blades 102 may be mounted on the main shaft 101, the two saw blades 102 are arranged at intervals in the axial direction of the main shaft 101, one of the saw blades 102 is arranged in front of the supporting seat 301, and the other saw blade 102 is arranged behind the supporting seat 301. Therefore, the structure of the cutting equipment can be simplified, and the cutting efficiency of the cutting equipment is improved.

Further, one or more cutting portions 100 may be included as the cutting portion for cutting the object 11. Also, for example, in the case of a casting in which a plurality of pieces 12 are formed in the left-right direction of the runner 13, the number of the cut portions 100 may be two, and the two cut portions 100 are provided at intervals in the left-right direction. Therefore, the sheet materials 12 at different positions in the left and right directions of the casting can be simultaneously cut by the plurality of cutting parts 100, and the cutting efficiency of the cutting equipment is improved.

The cutting machine of the present embodiment can clamp the object 11 to be cut, which has different sizes in the front-rear direction or different cutting positions, for example, with reference to the support base 301.

The following describes in detail the components of the cutting machine according to the present embodiment that can cut the object 11 to be cut having different sizes or different cutting positions.

[ cutting part 100]

Fig. 3 is a perspective view of the cutting unit 100, fig. 4 is a plan view of the cutting unit 100, fig. 5 is a sectional view taken along a-a in fig. 4, and in fig. 5, the main shaft 101 is partially cut away for the convenience of illustration, and referring to fig. 3 to 5 and additionally to fig. 1 and 2, as described above, the cutting unit 100 is mounted on the frame 700, and has the main shaft 101 and the saw blade 102 mounted to the outer periphery of the main shaft 101, and the saw blade 102 is adjustable in the axial direction of the main shaft 101 in a state of being loosened with respect to the main shaft 101.

Specifically, in some embodiments, the cutting portion 100 includes: a main shaft 101, a saw blade 102, a feeding portion 103, and a clamping portion 104. Wherein the outer circumference of the main shaft 101 is provided with a first external thread 105. The saw blade 102 is mounted to an outer circumference of the main shaft 101 to rotate as the main shaft 101 rotates. The feeding section 103 has a first nut 106. The first nut 106 is screwed with the first external thread 105, and the saw blade 102 is coupled to the first nut 106 and moves along the axial direction of the main shaft 101 with the first nut 106. The clamping portion 104 detachably fastens the saw blade 102 to the outer periphery of the main shaft 101.

In the present embodiment, since the position of the saw blade 102 on the main shaft 101 is adjusted by the feeding unit 103, not only the position of the saw blade 102 in the axial direction (i.e., the front-rear direction) of the main shaft 101 can be easily adjusted, but also the cutting unit 100 can cut the objects 11 to be cut which are different in size or position.

Further, since the feeding portion 103 has a screw feeding mechanism, the cutting portion 100 of the present embodiment can improve the adjustment efficiency and the adjustment accuracy of the saw blade 102 at least to some extent. Specifically, by performing adjustment using the screw feed mechanism, the first nut 106 can be fed precisely with rotation relative to the first male screw 105 of the main shaft 101, so that the position of the saw blade 102 in the axial direction of the main shaft 101 can be increased. Further, since the saw blade 102 is detachably fastened to the main shaft 101 by the clamp 104, the feed adjustment of the saw blade 102 can be performed in a case where the clamp 104 is released from the saw blade 102 (that is, the saw blade 102 is loosened with respect to the main shaft 101), and therefore, the adjustment efficiency of the saw blade 102 can also be improved.

The cutting unit 100 further includes, for example, a driving mechanism for driving the main shaft 101 to rotate, and the driving mechanism may be, for example, a known driving mechanism, and will not be described in detail here.

In order to more accurately grasp the adjustment distance of the saw blade 102 in the axial direction of the main shaft 101, the main shaft 101 is provided with a scale portion 107 in the axial direction. Specifically, the scale section 107 includes, for example, a scale 108, the spindle 101 is provided with a first mounting groove 109, and the scale 108 is mounted in the first mounting groove 109. The scale 108 may be, for example, a scale 108 in which the middle in the longitudinal direction is a zero point and scales are provided on both sides in the longitudinal direction. Thereby, both sides in the axial direction of the main shaft 101 can be realized, and the position of the saw blade 102 can be adjusted more precisely in both sides in the axial direction of the main shaft 101. The first mounting groove 109 is not particularly limited as long as it can accommodate the scale 108, and may be, for example, a shape slightly larger than the scale 108 and a depth slightly larger than the thickness of the scale 108.

Although the scale 108 is attached to the spindle 101 as an example in the above description, the scale is not limited to this. For example, the scale may be directly engraved on the main shaft 101 in the axial direction.

The length of the first male thread 105 provided on the main shaft 101 in the axial direction is set according to the distance to be adjusted by the saw blade 102. The position of the first male screw 105 in the axial direction of the main shaft 101 may be determined according to the position of the saw blade 102. In order to further improve the feeding accuracy of the feeding portion 103, the threads of the first external thread 105 and the first nut 106 are, for example, fine threads.

In addition, a commercially available second nut 110 is provided beside the first nut 106 in order to securely lock the first nut 106 against loosening of the first nut 106. After the adjustment of the first nut 106 is completed, the second nut 110 is rotated to be fitted to the first nut 106, thereby preventing the first nut 106 from loosening.

The first nut 106 is, for example, substantially in the form of a flange, one end of the first nut 106 is provided with a first flange 111 for connection to the saw blade 102, and the other end of the first nut 106 is provided with an internal thread 112 for screwing with the first external thread 105. The first flange portion 111 and the internal thread portion 112 are connected by a first connection portion 113. The first connection portion 113 is provided with a first inner hole 114, and the size of the first inner hole 114 is larger than the size of the outer diameter of the main shaft 101, thereby ensuring smooth feeding of the first nut 106 on the main shaft 101.

In some embodiments, to securely fasten the saw blade 102 to the main shaft 101, the clamp 104 comprises: a sleeve 115 and a fastener 116. A sleeve member 115 is coupled to the first nut 106, the sleeve member 115 is fitted over the main shaft 101 and moved in the axial direction of the main shaft 101 with the first nut 106, and the saw blade 102 is fastened to the sleeve member 115. The fastener 116 fastens the sleeve member 115 to the main shaft 101. By fastening the boss member 115 to the fastening member 116 of the main shaft 101, the saw blade 102 fastened to the boss member 115 cannot be reliably fastened to the main shaft 101, and also the fastening member 116 can be easily detached to make the boss member 115 movable in the axial direction with respect to the main shaft 101. Further, by providing the sleeve member 115 and the fastener 116 separately, the difficulty of processing can be reduced separately, and for example, a commercially available member can be used as the fastener 116 (described later) as it is.

To inhibit rotation of the saw blade 102 in the circumferential direction of the main shaft 101, the sleeve member 115 may be restricted from rotating relative to the main shaft 101. Specifically, the restricting structure of the sleeve member 115 is not particularly limited as long as the rotation relative to the main shaft 101 is restricted. For example, at least one side of the main shaft 101 in the radial direction may be provided with a flat portion, and the sleeve 115 may be provided with a second inner hole 117 that penetrates in the axial direction, and the cross-sectional shape of the second inner hole 117 may be matched to the shape of the portion of the main shaft 101 where the flat portion is provided, for example, in an oblong shape (see fig. 8 for assistance). This can restrict the rotation of the sleeve member 115 with respect to the main shaft 101. For example, a flat key (not shown) may be attached to the main shaft 101, and a key groove (not shown) may be formed in the sleeve member 115 to restrict the rotation of the sleeve member 115 with respect to the main shaft 101.

From the viewpoint of facilitating the movement of the sleeve member 115 in the axial direction relative to the main shaft 101, a structure in which a flat portion is formed on at least one side in the radial direction of the main shaft 101 is preferable. In addition, the size of the second inner hole 117 of the sleeve member 115 is preferably slightly larger than the size of the portion of the main shaft 101 with the flat position, so as to ensure that the sleeve member 115 can smoothly slide relative to the main shaft 101, and improve the adjustment efficiency.

Fig. 6 is a partial enlarged view at B in fig. 5, fig. 8 is a schematic view of an embodiment of the sleeve member 115, and referring to fig. 6 and 8 in addition to fig. 5, since the rotation of the sleeve member 115 relative to the main shaft 101 is restricted, in order to realize that the main shaft 101 can move in the axial direction of the main shaft 101 along with the rotation of the first nut 106 relative to the main shaft 101, the sleeve member 115 and the first nut 106 are rotatably connected. Specifically, the boss member 115 is provided with an annular first escape groove 119 and an annular mounting wall 120 at an end (hereinafter also referred to as "first end portion 118" for convenience of description) opposite to the first nut 106, and the mounting wall 120 is provided on a side of the first escape groove 119 close to the first nut 106. The first flange portion 111 of the first nut 106 is provided with an annular second avoiding groove 121, and the mounting wall 120 is received in the second avoiding groove 121. There is a gap between the mounting wall 120 of the sleeve member 115 and the second escape groove 121 in the axial direction, for example, the axial dimension of the second escape groove 121 is slightly larger than the thickness of the mounting wall 120. Further, for example, the axial dimension S1 of the second escape groove 121 is greater than the thickness S2 of the mounting wall 120 by 0.1mm ± 0.05 mm. Further, the first flange portion 111 is mounted with a first clamping member 122, and the first clamping member 122 is partially inserted into the first escape groove 119 of the boss member 115 in a state of being mounted to the first flange portion 111 and holds the mounting wall 120 of the boss member 115 together with the first flange portion 111. Thereby, the boss member 115 can be made to be connected to the first nut 106 and can move together with the first nut 106. Since the axial dimension S1 of the second escape groove 121 is larger than the thickness S2 of the mounting wall 120, the sleeve member 115 can move with the rotation of the first nut 106 even in a state where the sleeve member 115 is held by the first clamping member 122 together with the first flange portion 111. Further, since the axial dimension S1 of the second escape slot 121 is only 0.1mm ± 0.05mm greater than the thickness S2 of the mounting wall 120 (the dimension may be smaller than the pitch of the first external thread 105), the influence of the clearance on the adjustment accuracy of the saw blade 102 can be reduced, and the adjustment accuracy of the saw blade 102 can be ensured.

Although the above description has been made by taking as an example the case where the rotation of the sleeve member 115 with respect to the main shaft 101 is limited, the present invention is not limited thereto. Since the fastening member 116 can reliably fasten the boss member 115 to the main shaft 101, the boss member 115 may also be provided so as to be rotatable with respect to the main shaft 101 in a state where it is not fastened by the fastening member 116. This enables smooth sliding of the sleeve member 115 with respect to the main shaft 101. Further, in this embodiment, a smaller gap may be designed between the mounting wall 120 of the sleeve member 115 and the second avoiding groove 121 as long as the gap can allow the sleeve member 115 to be deformed in the radial direction of the main shaft 101 when being clamped (clasped) by the fastening member 116 (described later).

With continued reference to fig. 8 and with additional reference to fig. 3 and 4, the structure of the saw blade 102 fastened to the bushing member 115 is not particularly limited, and for example, the saw blade 102 may be directly fastened to the other axial end (hereinafter also referred to as "second end 123" for convenience of description) of the bushing member 115 by a screw. Specifically, the second end portion 123 is provided with a support portion 124 for supporting the circumferential direction of the saw blade 102, and a second flange portion 125 for restricting the saw blade 102 in the axial direction. The second flange portion 125 is disposed outside the second end portion 123, and the support portion 124 is adjacent to the second flange portion 125 and inside the second flange portion 125. The blade 102 is fitted over the support portion 124 and abuts the second flange portion 125. In addition, the sleeve member 115 is sleeved with a second clamping member 126, and the second clamping member 126 is sleeved on the sleeve member 115 from the first end portion 118 of the sleeve member 115. The second clamping member 126 and the second flange portion 125 are screwed to each other to firmly clamp the saw blade 102 to the bushing member 115. In addition, when it is desired to disassemble the saw blade 102, the second clamping member 126 is removed and the saw blade 102 is removed.

Fig. 7 is a schematic view of an embodiment of the fastening member 116, and referring to fig. 7, since the saw blade 102 generates a strong reaction force when cutting the work piece 11, which may cause vibration of the saw blade 102, in order to securely fix the bushing member 115 to the main shaft 101 so that the saw blade 102 is securely fastened to the main shaft 101, the fastening member 116 is a fixing collar which axially deforms the bushing member 115 to fasten it to the main shaft 101. Specifically, the fixing collar as the fastener 116 has a notch 127 formed at one end in the radial direction, for example, and the notch 127 can be pulled by a screw, for example, to contract the fixing collar in the axial direction, thereby providing a sufficient clamping force. The fixing collar is fitted around the outer periphery of the sleeve member 115, and when the notch 127 is pulled by a screw, the fixing collar is contracted in the axial direction so that the sleeve member 115 is also contracted in the axial direction. Thereby, the bushing member 115 can be tightly held on the main shaft 101, so that the saw blade 102 is not vibrated with respect to the main shaft 101 by a large reaction force when the saw blade 102 cuts, for example, a cast product, and the saw blade 102 can be surely operated. Alternatively, the stationary collar may be a commercially available stationary collar, for example.

With continued reference to fig. 8, in some embodiments, in order to facilitate deformation and contraction of the sleeve member 115, a plurality of slits 129 are circumferentially spaced apart from each other in the main body portion 128 of the sleeve member 115, and the slits 129 extend through the main body portion 128 of the sleeve member 115 in a radial direction thereof and through one axial end of the main body portion 128 in an axial direction thereof of the sleeve member 115. Specifically, the split portion 129 penetrates the first end portion 118 in the axial direction of the bushing 115. Further, the split portion 129 extends to a position close to the support portion 124 along the other end in the axial direction of the boss member 115. Preferably, the split portion 129 does not extend to the position of the support portion 124. This makes it possible to reliably clamp the main shaft 101 by easily contracting and deforming the sleeve member 115 while being clamped by the fixing collar, and to improve the mounting accuracy of the saw blade 102 by suppressing deformation of the support portion 124 for supporting the saw blade 102. Further, in the case where the second bore 117 is oblong, the slit portion 129 cuts out the inner side wall portion 130 in the second bore 117, which is planar. In a state where the sleeve member 115 is tightly held by the main shaft 101, the inner wall portion 130 is tightly fitted to the portion of the main shaft 101 where the flat portion is opened, whereby the sleeve member 115 can be further reliably restricted from rotating relative to the main shaft 101.

With continued reference to fig. 8 and with additional reference to fig. 5, in some embodiments, to further facilitate deforming and contracting the sleeve member 115, the main body portion 128 is further provided with a plurality of annular grooves 131 at axially spaced intervals. Specifically, the annular groove 131 is opened at an interval between the first avoiding groove 119 and the support portion 124. A fixing collar as a fastener 116 is fitted to the portion of the sleeve member 115 provided with the annular groove 131. When the sleeve member 115 is deformed by the fixing collar, the slit 129 penetrates the first end portion 118 and does not extend to the position of the support portion 124, so that the deformation amount is the largest at the position of the first end portion 118 and is smaller at the position closer to the support portion 124 when the sleeve member 115 is deformed, that is, the portion between the first end portion 118 and the support portion 124 is slightly bent with reference to the inner side of the support portion 124 (i.e., the side closer to the first end portion 118) by the clamping force of the fixing collar. Accordingly, by providing the annular groove 131, the sleeve 115 can be easily bent, and the portion of the sleeve 115 close to the support portion 124 can be prevented from being damaged or even cracked by the bending.

In addition, although the above description has been given of the example in which the sleeve member 115 is fastened to the main shaft 101 by deforming and contracting the sleeve member 115 in the axial direction, the present invention is not limited to this. For example, when the cutting reaction force of the saw blade 102 is not particularly large, the fastening member 116 may be, for example, a set screw, and the boss member 115 may be, for example, a bushing (not shown) having a threaded hole formed in the main body portion 128. The sleeve 115 is directly pressed against the main shaft 101 by a set screw.

Alternatively, the second end 123 of the sleeve member 115 may be directly provided as a fixing collar, the blade 102 may be attached to an axial end surface of the fixing collar, and the fixing collar may be directly clamped to the main shaft 101 to fix the blade 102 to the main shaft 101.

Further, the boss member 115 and the fastener 116 may be respectively processed using, for example, a metal member such as stainless steel, aluminum alloy, or the like, but are not limited thereto. For example, in the case where the cutting reaction force of the saw blade 102 is not particularly large, a plastic member that is easily deformed, for example, may be used for the boss member 115.

Fig. 9 is a schematic view of another embodiment of the cutting section 100, and referring to fig. 9, in the case where a plurality of (e.g., two) saw blades 102 are provided on a main shaft 101, each saw blade 102 is adjustably mounted to the same main shaft 101 by the feeding section 103 and the clamping section 104 of the above-described embodiments, respectively. By providing, for example, a plurality of saw blades 102, the efficiency of the cutting can be greatly improved in cases where, for example, a casting requires multiple cuts.

[ Lift drive device 400]

Fig. 10 is a schematic perspective view of the elevation driving apparatus 400, and in fig. 10, the first transmission unit 402 on the right side of the frame 700 is partially cut away for convenience of illustration. Referring to fig. 10, the elevation driving device 400 is used to drive the cut object 11, which is held by the support base 301 and the pressing portion 302, to be elevated. The elevation driving apparatus 400 includes: an elevating part 404, two first transmission parts 402, and a driving motor 403. The elevating unit 404 includes an upper mounting plate 401, a lower mounting plate 405, and two connecting screws 406. One connecting screw 406 connects the left side of the upper mounting plate 401 and the left side of the lower mounting plate 405, respectively. The other connecting screw 406 connects the right side portion of the upper mounting plate 401 and the right side portion of the lower mounting plate 405, respectively. A support base 301 for holding the work 11 is provided on the lower mounting plate 405. The pressing portion 302 for pressing the cut object 11 is provided on the upper mounting plate 401. The two first transmission portions 402 are respectively mounted to left and right side portions of a frame 700 (only a main portion of the frame 700 is illustrated for convenience of illustration in the drawing) of the cutting apparatus. Each of the first transmission units 402 has a lead screw nut 407, and the lead screw nut 407 is screwed to the connection lead screw 406. The driving motor 403 is provided to the frame 700, is connected to the two lead screw nuts 407, and drives the two lead screw nuts 407 to rotate so as to raise and lower the elevating part 404.

In this embodiment, since the upper mounting plate 401 and the lower mounting plate 405 are supported by being driven up and down using the lead screw transmission mechanism, the impact resistance is strong and the structure is reliable. Specifically, since the elevation driving device 400 uses the screw transmission mechanism, not only can the entire elevation part 404 be driven to ascend and descend, but also when the cutting blade 102 of the cutting machine cuts the object 11 to be cut, the elevation part 404 can be stably supported, oscillation or shaking of the elevation part 404 due to the impact force of cutting can be suppressed, and the reliability of the structure of the elevation part 404 can be improved. Further, by using the screw transmission mechanism, it is possible to suppress sudden fall of the lifting unit 404 even in the case of runaway, and to improve the safety of the apparatus.

[ pressing device 300]

Fig. 11 is a perspective view of the support base 301, fig. 12 is a perspective view of the pressing portion 302, and with reference to fig. 11 and 12 and with additional reference to fig. 1, 2, and 10, in the following description, for convenience of describing the support base 301 and the pressing portion 302 as a whole, a portion including the support base 301 and the pressing portion 302 will be collectively referred to as a pressing device 300. As described above, the support base 301 holds the object 11 to be cut in the vertical direction. The pressing portions 302 are respectively disposed above the supporting base 301 and press the work piece 11.

Referring to fig. 11, in order to easily hold the work 11, the support base 301 is provided with a first groove portion 307 for positioning the work 11, and the first groove portion 307 extends in the left-right direction. Specifically, taking a casting as an example, the bottom of the casting as the work piece 11 generally has two positioning columns 14, and by providing the first groove portion 307 extending in the left-right direction, the positioning columns 14 can be accommodated in the first groove portion 307, thereby positioning the casting. The first groove 307 is provided at an upper portion of the support base 301 and continuously extends in the left-right direction. Since there may be an error in the distance of the positioning columns 14 in the left-right direction, by providing the first groove portion 307 to extend in the left-right direction, the cut object 11 can be easily placed in the first groove portion 307. In addition, since the distances between the positioning columns 14 of different castings in the left-right direction are also different, the castings of different sizes can be adapted by providing the first groove portions 307 extending in the left-right direction, thereby improving the versatility of the cutting apparatus.

Referring to fig. 12, each pressing portion 302 includes: a first cylinder 303, a connecting member 304 and a pressing member 305. The connecting member 304 is connected to the output end 306 of the first cylinder 303, and ascends and descends along with the output end 306. The pressing member 305 is attached to the link member 304 and is adjustable in the left-right direction with respect to the link member 304. The pressing pieces 305 of the respective pressing portions 302 independently press the work piece 11 in a state where the output end 306 of the first cylinder 303 of the respective pressing portions 302 is extended.

Since a plurality of the pressing portions 302 are provided and the pressing pieces 305 of the respective pressing portions 302 can be adjusted in the left-right direction, the respective pressing pieces 305 can be adjusted in accordance with the object 11 to be cut, such as a casting, so that the object 11 to be cut can be reliably pressed. Specifically, since the pressing tool 305 can be adjusted in the left-right direction, the position of the pressing cast can be adjusted in accordance with the shape of the surface of the work 11, such as a metal, and the work 11 can be reliably pressed. In addition, even when the sizes of the objects to be cut 11 are different, the presser 305 can be easily adjusted according to the size of the objects to be cut 11, thereby improving the versatility of the cutting apparatus.

The pressing portions 302 may include two portions, and are spaced apart from each other in the left-right direction. Specifically, the first cylinders 303 of the pressing portions 302 are attached to the upper attachment plate 401 at intervals in the left-right direction. By providing two pressing portions 302, the pressing pieces 305 of the respective pressing portions 302 can be adjusted in the left-right direction as needed, whereby the position of pressing the cast can be adjusted in accordance with the shape of the surface of the work 11 such as a metal, and the work 11 can be reliably pressed.

In order to easily adjust the pressing piece 305, the coupling piece 304 is provided with a second groove portion 308 extending in the left-right direction, and the pressing piece 305 slides along the second groove portion 308. Specifically, for example, the cross section of the second groove portion 308 has a T-shape. Correspondingly, the upper portion of the pressing piece 305 is also provided in a T-shape matching the cross section of the second groove portion 308. Thereby, the pressing piece 305 slides with respect to the link 304 with its upper portion held by the second groove portion 308. Although the second groove portion 308 has been described as having the T-shape, the present invention is not limited thereto. The second groove portion 308 may have any shape as long as it can hold the pressing member 305.

In order to easily lock the pressing member 305, a third groove 309 extending in the left-right direction is provided on the front side of the pressing member 305, the third groove 309 communicates with the second groove 308, and the upper portion of the pressing member 305 is locked in the second groove 308 by a screw member 310 passing through the third groove 309. Further, a fourth groove 311 for pressing the workpiece 11 is provided in a lower portion of the pressing tool 305, the fourth groove 311 penetrates the pressing tool 305 in the left-right direction, and the cross section of the fourth groove 311 is V-shaped.

In some embodiments, in order to easily adjust the first cylinder 303 of the compressing part 302, the compressing part 302 further includes a solenoid valve 312 for controlling the first cylinder 303, and the solenoid valve 312 may be disposed beside the first cylinder 303.

[ positioning device 200]

Fig. 13 is a perspective view of a rear view direction of the cutting apparatus having the positioning device 200, fig. 14 is a schematic view of the positioning device 200 in fig. 13, fig. 15 is a schematic view of the up-down adjusting portion 202 in fig. 14, and fig. 16 is a schematic view of the front-back adjusting portion 203 in fig. 14. Referring to fig. 13 to 16, the cutting apparatus of the present embodiment may further include a positioning device 200 for positioning the object 11 to be cut. The positioning device 200 includes a front-rear adjusting portion 203 adjustable in the front-rear direction, and a positioning portion 204 adjusted by the front-rear adjusting portion 203 in the front-rear direction. The positioning portion 204 includes a first driving element 205 and a positioning member 206, the positioning member 206 is connected to the first driving element 205 and driven by the first driving element 205 to extend and contract in the front-rear direction, and when the object 11 is clamped to the cutting device in a state where the positioning member 206 is driven to extend, the object 11 abuts against the positioning member 206.

With continued reference to fig. 14, the positioning device 200 further includes: a first base 201 and an up-down adjusting portion 202. Wherein the first base 201 is mounted to the chassis 700. The vertical adjustment portion 202 is provided on the first base 201 and is adjustable in the vertical direction. The front-rear adjusting portion 203 is provided to the up-down adjusting portion 202, and is adjustable in the front-rear direction. The positioning portion 204 is provided to the front-rear adjusting portion 203. The positioning member 206 is provided with a positioning surface 207 extending in the left-right direction, and when the object 11 is clamped to the cutting device, the object 11 abuts against the positioning surface 207.

By providing the positioning device 200, the object 11 to be cut in the cutting apparatus can be reliably positioned. Specifically, in the positioning apparatus 200 of the present embodiment, since the vertical adjustment portion 202 and the vertical adjustment portion 203 are provided and the positioning member 206 is provided with the positioning surface 207 extending in the left-right direction, the position of the positioning member 206 can be adjusted according to the shape of the surface of the workpiece 11, for example, a metal member, and the workpiece 11 can be reliably positioned. Further, since the positioning member 206 is provided with the positioning surface 207 extending in the left-right direction, the holding surface of the positioning member 206 can be increased, and the object 11 to be cut in the cutting machine can be positioned more reliably. In addition, the size of the cut object 11 with different sizes can be matched, and the universality of the cutting equipment is improved.

The positioning device 200 may be mounted to the frame 700 of the cutting apparatus behind the support base 301. Before the cut object 11 is clamped to the support base 301, the first driving element 205 of the positioning device 200 drives the positioning member 206 to extend forward. When the work 11 is mounted on the support base 301, the work 11 abuts against the positioning surface 207 of the positioning member 206 extending in the left-right direction, and thus the work 11 can be reliably held and positioned. After the clamping of the work piece 11 is completed, the first driving member 205 drives the positioning member 206 to retract backward, preventing the cutting blade 102 from cutting the positioning member 206.

The positioning surface 207 may be a plane surface, and the length of the positioning surface 207 extending in the left-right direction is greater than the width of the portion of the cut object 11 abutting against the positioning surface 207. Taking a casting as an example, the casting includes a runner 13, and the length of the positioning surface 207 extending in the left-right direction is greater than the width of the runner 13 of the casting. Thus, even if the size or the like of the runner 13 varies or differs, the positioning surface 207 can be ensured to completely cover the size of the runner 13, and the positioning member 206 can be ensured to reliably hold and position the casting. The positioning member 206 may have a plate shape, a bar shape, a column shape, or the like extending in the left-right direction.

The first driving element 205 is a cylinder. A cylinder as a first driving element 205 is attached to the front-rear adjusting portion 203, and an adjusting position of the positioning portion 204 in the front-rear direction is set by the front-rear adjusting portion 203. The positioning member 206 may be mounted directly to the telescoping rod 208 of the cylinder. Thus, the positioning member 206 can hold and position the casting as the work 11 when the cylinder as the first driving element 205 is extended. When the cylinder as the first driving element 205 is retracted, the cutting blade 102 can be prevented from cutting to the spacer 206.

Wherein the first rack 209 is mounted to the first base 201. The first guide 210 is mounted to the first base 201 to be guided in the up-down direction. The first sliding member 211 slides in the up-down direction with respect to the first guide 210. A first gear 212 is engaged with the first rack 209 and is rotatably mounted to the first slide assembly 211. The first fastening portion 213 fastens or rotates the first gear 212 with respect to the first slider assembly 211. In the present embodiment, by rotatably mounting the first gear 212 to the first sliding member 211, the first sliding member 211 can slide in the up-down direction when the first gear 212 is rotated. In addition, by providing the adjusting structure of the rack and pinion, the structure of the vertical adjusting portion 202 can be simplified, and the vertical adjustment can be performed easily and the cost can be reduced.

The first guide 210 may select, for example, a guide shaft or a linear slide, and in the case of selecting a guide shaft, two guide shafts may be selected.

The first sliding assembly 211 may include a first mounting block 214, and a first sliding bushing 215 is mounted on the first mounting block 214, and the first sliding bushing 215 is sleeved on the first guide member 210 and can slide up and down along the first guide member 210. To mount the first gear 212 to the first mounting block 214, the first mounting block 214 rotatably mounts a first rotating shaft 216 thereon, and the first gear 212 is mounted to one axial end of the first rotating shaft 216. The first shaft 216 may be rotatably mounted to the first mounting block 214 by, for example, a bearing (not shown). Thus, when the first rotation shaft 216 is rotated, the first gear 212 and the first rotation shaft 216 are rotated in synchronization. When the rotation of the first rotating shaft 216 is restricted, the first gear 212 is also restricted, so that the movement of the first sliding member 211 in the up-down direction is restricted.

The first fastening portion 213 includes, for example: a first fixing collar 217 and a first screw 218, wherein the first fixing collar 217 is mounted to the first mounting block 214, a first hole part 219 is formed on the first fixing collar 217, the first rotating shaft 216 passes through the first hole part 219, and the first screw 218 enables the first rotating shaft 216 to rotate relative to the first hole part 219 or enables the first rotating shaft 216 to be fixed in the first hole part 219.

To easily rotate the first shaft 216, a first hand wheel 221 may be mounted to the other axial end of the first shaft 216.

With continued reference to fig. 16, the front-rear adjusting portion 203 includes: a second base 222, a second guide 223, a second slide assembly 224, a second rack 225, a second gear 226, and a second fastening portion 227. Wherein the second base 222 is mounted to the first slider assembly 211. The second guide 223 is mounted to the second base 222 to guide in the front-rear direction. The second slide module 224 slides in the front-rear direction with respect to the second guide 223. A second rack 225 is mounted to the second slide assembly 224. The second gear 226 is engaged with the second rack 225 and is rotatably mounted to the second base 222. The second fastening portion 227 enables the second gear 226 to be fastened or rotatable with respect to the second base 222. In this embodiment, the second gear 226 is mounted to the second base 222 by mounting the second rack 225 to the second slide assembly 224. When the second gear 226 is rotated, the second slide assembly 224 can slide in the front-rear direction. In addition, by providing the adjusting structure of the rack and pinion, the structure of the front-rear adjusting portion 203 can be simplified, and the cost can be reduced while the front-rear adjustment can be performed easily.

The second base 222 is mounted to the first mounting block 214 of the first sliding assembly 211 to be lifted up and down together with the first mounting block 214. The second guide 223 may select, for example, a guide shaft or a linear slide, and in the case of selecting a guide shaft, two guide shafts may be selected.

The second sliding assembly 224 includes a second mounting block 228, a second sliding bushing 229 is mounted on the second mounting block 228, the second sliding bushing 229 is fitted over the second guide 223 and is slidable back and forth along the second guide 223, and the second rack 225 is mounted to the second mounting block 228. Specifically, for example, in the case of selecting a guide shaft as the second guide 223, the second slide bushing 229 may select, for example, a linear bearing. The second slide bushing 229 is insert-mounted to the second mounting block 228. Thereby, the second slide module 224 can slide smoothly in the front-rear direction with respect to the second guide 223. In addition, in the case of selecting a linear guide as the second guide 223, the second sliding bushing 229 may be replaced with a slider that matches the linear guide.

In order to mount the second gear 226 on the second base 222, a third mounting block 230 is mounted on the second base 222, a second rotating shaft 231 is rotatably mounted on the third mounting block 230, and the second gear 226 is mounted on one axial end of the second rotating shaft 231. The second rotating shaft 231 may be rotatably mounted to the third mounting block 230 by, for example, a bearing (not shown). Thus, when the second rotation shaft 231 is rotated, the second gear 226 and the second rotation shaft 231 are rotated in synchronization. When the rotation of the second rotating shaft 231 is restricted, the second gear 226 is also restricted, so that the movement of the second sliding assembly 224 in the front-rear direction is restricted.

The second fastening part 227 includes: a second fixing collar 232 and a second screw member 233. The second fixing collar 232 is attached to the third attachment block 230, and the second fixing collar 232 has a second hole (hidden by the third attachment block 230, not shown, refer to the first hole 219) through which the second shaft 231 passes. The second screw member 233 allows the second rotating shaft 231 to be rotated with respect to the second hole portion, or allows the second rotating shaft 231 to be fixed in the second hole portion. To easily rotate the second rotating shaft 231, a second wheel 235 is mounted to the other axial end of the second rotating shaft 231.

[ striker device 500]

Fig. 17 is a schematic view of the striker device 500 seen from a top view, fig. 18 is a perspective view of the striker device 500, and fig. 19 is a perspective view of the striker assembly 502. Referring to fig. 1, 17 to 19, the cutting apparatus of the present embodiment may further include a material blocking device 500. Wherein, dam device 500 includes: a mounting base plate 501 and at least two stock stop assemblies 502. The mounting substrate 501 is mounted to the frame 700 of the cutting apparatus. The dam assemblies 502 are respectively mounted on the mounting base plate 501 and are adjustable in the left-right direction relative to the mounting base plate 501. Each striker assembly 502 has a striker plate 503, the striker plate 503 crosses the cutting position of the cutting blade 102 in the up-down direction, and at least one striker plate 503 is disposed to be located at least on the left side of the cut object 11 when viewed from the up-down direction, and at least one striker plate 503 is disposed to be located on the right side of the cut object 11 when viewed from the up-down direction.

By providing the material blocking device 500, the fallen cut object 11 can be prevented from splashing. Specifically, since at least one striker plate 503 is provided on each of the left and right sides of the object 11 to be cut, even if the object 11 to be cut is scattered when the object 11 to be cut is cut, the object is caught by the striker plate 503 and is limited to a certain range. Therefore, the cut object 11 can be accurately dropped into a blanking device 600 (described later) located below the support base 301 after being cut. Further, the material blocking assembly 502 is arranged to be adjustable in the left-right direction, so that the material blocking assembly can adapt to cut objects 11 with different sizes, and the universality of the material blocking device 500 is improved.

When the cutting blade 102 includes two sets positioned in the front-rear direction of the supporting seat 301 and cuts the object 11 to be cut in the front-rear direction of the supporting seat 301, respectively, the striker 500 may include two, one disposed in front of the cutting blade 102 and the other disposed behind the cutting blade 102.

With continued reference to fig. 17, the tail assembly 502 of each tail 500 may include more than three. Specifically, for example, when the sheet 12 of the casting has only one row in the left-right direction, only two striker assemblies 502 are required, wherein the striker plate 503 of one striker assembly 502 is disposed on the left side of the casting and the striker plate 503 of the other striker assembly 502 is disposed on the right side of the casting. When the sheet materials 12 of the casting have a plurality of rows along the left-right direction, the material blocking assemblies 502 can include more than three, and each material blocking assembly 502 separates the sheet materials 12 in the left-right direction, so that the sheet materials 12 in different rows can be prevented from colliding with each other when being cut.

With continued reference to fig. 18 and 19, in order to easily and simply adjust the striker assembly 502 in the left-right direction, a second mounting groove 504 extending in the left-right direction is provided on the mounting base plate 501, and the striker assembly 502 is adjustable along the second mounting groove 504. In addition, in order to further adapt the striker plate 503 to the cut objects 11 with different sizes, the striker plate 503 is arranged to be adjustable in the front-rear direction. Specifically, for example, the striker assembly 502 has a first adjusting member 505, a third mounting groove 508 extending in the front-rear direction is provided on the first adjusting member 505, and the striker plate 503 is adjustably mounted to the first adjusting member 505 along the third mounting groove 508. Therefore, the striker plate 503 can be adjusted not only in the left-right direction but also in the front-rear direction, so that the striker plate 503 can be easily and simply adjusted in the front-rear direction to be adapted to the objects 11 to be cut of different sizes.

[ Blanking device 600]

With continued reference to fig. 1 and 2, the cutting apparatus of the present embodiment may further include a blanking device 600. Specifically, the blanking device 600 includes a conveyor line driven by a motor. A conveying line is provided at a lower portion of the supporting base 301 and extends to an outside of the cutting apparatus (e.g., an outside of the frame 700), and receives and conveys the sheet materials 12 cut off from the work-piece 11 by the cutting blade 102.

In this embodiment, since the motor-driven conveying line is provided below the support base 301 for supporting the object 11 to be cut, the sheet material 12 dropped on the conveying line can be reliably conveyed, and the sheet material 12 can be prevented from being stacked. Specifically, since the sheet materials 12 are conveyed through the conveying line that rotates endlessly, even if the shape of the sheet materials 12 is irregular or burrs exist, the sheet materials 12 may fall off when being conveyed to the rear end of the conveying line. Therefore, the sheet materials 12 falling down to the conveying line can be reliably conveyed out. In addition, when there is another line (not shown) that interfaces with the blanking apparatus 600 of the present embodiment, the sheet material 12 can be directly transferred to another processing facility without manual collection or the like.

While embodiments of the invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
