Technical Field

The invention relates to the field of glass breaking equipment, in particular to a fracturing knife wheel for breaking glass. In addition, the invention also relates to a glass cutting machine for splitting.

Background

In the glass processing process, splintering is an important process. Before breaking, a cutting machine is usually used to cut the glass surface, leaving a cutting line on the glass surface. And then applying certain pressure on the cutting line of the glass by using a glass splitting machine to enable the glass to generate micro deformation and split along the cutting line, thereby completing the splitting process.

The traditional glass breaking process mainly comprises a linear cutter, wherein a cutter edge of the cutter is cut into a cutting line on the surface of glass, and the glass can be broken by pressing downwards. However, such a glass breaking machine is suitable only for linearly cut glass, and for irregularly cut glass, since the cutting line is irregularly shaped, for example, an R-shaped corner, a U-shaped notch, a C-shaped corner, or the like is cut, it is impossible to break the glass using such a glass breaking machine. In addition, when the traditional glass sheet splitting machine is used for splitting, the problems of breakage, breakage points and the like are easy to occur near the splitting position of the glass, and the yield of split products is reduced.

Therefore, the conventional glass breaking machine cannot break the irregularly-shaped cut glass, and the yield of the broken glass product is low, which is a problem to be solved by technical personnel in the field.

Detailed Description

The following provides a detailed description of the embodiments of the present application. In the description of the present application, it is to be understood that the terms "upper", "lower", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used for convenience of description only, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application. The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

The inventor has analyzed that the problems of fracture, edge breakage and transverse crack of the cutting line are easy to occur when the traditional glass sheet splitting machine is used for splitting, and the reason is that when a cutter of the glass sheet splitting machine presses the glass at the cutting line, transverse force is generated in addition to longitudinal force generated on the glass at the cutting line. The transverse acting force generates mechanical damage to the glass, so that the problems of breakage, edge breakage, transverse crack and the like easily occur near the cutting line of the glass, and the yield of broken pieces is low.

Therefore, referring to fig. 1 and fig. 2, a first embodiment of the present invention provides a fracturing cutter wheel for fracturing, including a cutter wheel base 1, wherein a disk surface 2 on two sides of the cutter wheel base 1 is provided with a through cutter shaft hole 3; the disc surfaces 2 on the two sides of the cutter wheel base body 1 respectively extend outwards to form two conical surfaces 4; the two conical surfaces 4 extend outwards to form fracturing platforms 5, and the fracturing platforms 5 are coaxial with the cutter shaft holes 3. That is, the fracturing platform 5 is annular, the axis of the fracturing platform is the same as the axis 31 of the cutter shaft hole 3, and at this time, the included angle α between the fracturing platform 5 and the conical surface 4 is an obtuse angle.

the cutter wheel base herein is generally cylindrical or similar in shape. Taking a cylindrical cutter wheel base body as an example, the side surfaces of the cutter wheel base body refer to the upper bottom and the lower bottom of the cylinder. And the fracturing platforms formed by outwards extending the two conical surfaces are annular. When the fracturing cutter wheel is processed, a cylindrical base material can be used as a cutter wheel base body, the bottom surfaces of the two cylinders are disc surfaces, through cutter shaft holes are formed in the disc surfaces, the intersecting positions of the disc surfaces and the side surfaces of the cylinders are chamfered to form conical surfaces, and the rest side surfaces are fracturing platforms. In addition, the fracturing platform can be finely ground, so that the surface of the fracturing platform is smooth and flat, and the roughness coefficient of the fracturing platform is reduced, thereby ensuring that the glass cannot be damaged in the process of fracturing.

When the fracturing cutter wheel is used, the fracturing cutter wheel can be arranged on a cutter wheel shaft of the cutting machine, namely the cutter wheel shaft penetrates through the cutter shaft hole 3 of the fracturing cutter wheel, and the fracturing cutter wheel is arranged on a cutter rest of the cutting machine, so that the fracturing cutter wheel can rotate around the cutter wheel shaft. When the glass is cracked, the fracturing platform 5 of the fracturing knife wheel is firstly propped against the surface of the glass, so that the fracturing platform 5 is uniformly and vertically contacted with the two sides of the cutting line. The fracturing table 5 is then caused to exert pressure on the glass and to move along the trajectory of the cutting line on the glass surface. The vertical force applied by the fracturing platform 5 acts on the glass, the cutting line on the glass longitudinally extends, so that the glass is separated, and the glass at the cutting line cannot be subjected to transverse acting force in the process, so that the problems of cutting line breakage, edge breakage, transverse crack generation and the like caused by mechanical damage are not easy to generate. By adopting the fracturing knife wheel, no matter the cutting line is not a straight line, the knife rest can control the fracturing knife wheel to move along the track of the cutting line, thereby realizing the splitting operation of the specially-shaped cut glass.

In addition, generally, the operation platform needs to be replaced after the glass is cut, and the glass is transferred from the operation platform of the cutting machine to the operation platform of the splitting machine. By adopting the fracturing knife wheel, the fracturing knife wheel can be arranged on the cutting machine, so that the cutting machine drives the knife rest according to the cutting route of the fracturing knife wheel to drive the fracturing knife wheel to move, and the fracturing is finished. Therefore, by adopting the fracturing cutter wheel, glass can be directly cracked after being cut, and an operation platform does not need to be replaced, so that the operation efficiency is greatly improved, and the equipment space is saved.

The fracturing knife wheel can be used for single-side splitting, double-side splitting, asymmetric splitting and the like. The glass splitting device is not only suitable for the splitting process of conventional glass, but also suitable for the splitting process of light weight and fineness.

Optionally, referring to fig. 3 to 9, a positioning groove 6 is formed on the fracturing platform 5, the positioning groove 6 divides the fracturing platform 5 into a first platform 51 and a second platform 52, and two groove walls 61 of the positioning groove 6 intersect to form a positioning line 62. Here, the groove wall 61 may be a convex curved surface, a flat surface, or a concave curved surface, etc. Specifically, in one implementation, referring to fig. 3 to 5, both groove walls 61 are convex curved surfaces, i.e., convex arc surfaces are formed between the positioning line 62 and the first platform 51 and the second platform 52, respectively. In another implementation, referring to fig. 6 to 7, both groove walls 61 are flat, i.e. the positioning line 62 forms a slope with the first platform 51 and the second platform 52. In another implementation, referring to fig. 8 to 9, both groove walls 61 are concave curved surfaces, i.e. concave arc surfaces are formed between the positioning line 62 and the first platform 51 and the second platform 52, respectively.

For the fracturing cutter wheel (please refer to fig. 10) in which the groove wall 61 of the positioning groove 6 is a plane, and the fracturing cutter wheel in which the groove wall of the positioning groove is an inner concave curved surface, the connection between the groove wall 61 and the first platform 51 and the connection between the groove wall 61 and the second platform 52 may be further made into a first arc chamfer 63. In addition, the joint of the conical surface 4 and the fracturing platform 5 (including the first platform 51 and the second platform 52) can also be provided with a second arc chamfer 53.

when the glass is cracked, particularly when the glass is cracked in a special shape, the fracturing knife wheel needs to run at a high speed and move along a cutting line track. During this process, the fracturing cutter wheel may oscillate slightly, especially when encountering curved track segments. At this moment, the fracturing cutter wheel with the two groove walls 61 being convex curved surfaces or the fracturing cutter wheel with the groove walls 61 being concave curved surfaces or planes and the first arc chamfer 63 at the joint of the groove walls 61 and the fracturing platform is adopted, so that the phenomenon that the joint of the fracturing platform 5 and the positioning groove 6 generates secondary scratch to glass when the fracturing cutter wheel swings and the product quality of a splitting process is influenced can be avoided. And a second arc chamfer 53 is formed at the joint of the conical surface 4 and the fracturing platform 5, so that the secondary scratch of the joint of the fracturing platform 5 and the conical surface 4 on the glass can be avoided when the fracturing cutter wheel is inclined.

in addition, referring to fig. 11, the conical surface 4 itself may also be a convex curved surface, which is smoothly connected with the fracturing platform 5, so that not only is the secondary scratch of the glass generated at the joint of the conical surface 4 and the fracturing platform 5 avoided, but also the resistance of the fracturing cutter wheel during high-speed operation is reduced.

When the fracturing platforms are placed against the glass, the first platform 51 and the second platform 52 can be placed on both sides of the cutting line, and the cutting line is aligned by the positioning line 62 in the positioning groove 6, so that whether the first platform 51 and the second platform 52 are uniformly positioned on the glass on both sides of the cutting line can be clearly observed to confirm whether the deviation occurs. Here, when the sizes of the cutting line and the positioning groove 6, especially the positioning line 62, are very small and are difficult to distinguish by naked eyes, an imaging device or the like can be used to collect images of the enlarged cutting line and the fracturing cutter wheel, so as to rapidly position the cutting line, so that the fracturing platform 5 can be uniformly contacted with the glass on both sides of the cutting line, and further uniformly apply pressure to the glass on both sides of the cutting line.

generally, the positioning groove 6 is located at the center of the fracturing table 5, so that the width W1 of the first table 51 and the width W2 of the second table 52 divided by the positioning groove 6 are the same.

In one example, referring to fig. 4, 7 and 9, the groove depth H of the positioning groove 6 relative to the fracturing platform 5 is 0.05mm to 0.4mm, and the notch width w0 of the positioning groove 6 is 0.1mm to 0.4 mm; the sum of the width W1 of the first platform 51 and the width W2 of the second platform 52 is 0.15mm-0.35 mm. Here, in the case where the thickness of the cutter wheel base 1 is constant, the widths of the first and second lands 51 and 52 are mainly determined by the width of the positioning groove 6. If the width W0 of the positioning groove 6 is too large, which results in the width W1 of the first platform 51 and the width W2 of the second platform 52 being too small, the pressure of the pressure acting on the glass is too large, which may cause the glass to break points or cut sections to break, and affect the quality of the split sheet. If the width of the positioning groove 6 is too small, the first platform 51 and/or the second platform 52 may easily press the cutting line during the splitting process, which may also affect the splitting quality.

Referring to fig. 2, 4, 7 and 9, the diameter D of the cutter wheel base 1 is 1.5mm-3.5mm, and the thickness T is 0.65mm-1.0 mm; the diameter d of the cutter shaft hole 3 is 0.4mm-0.8 mm. Referring to fig. 3 to 5, both of the groove walls 61 are convex curved surfaces, the cross section of the groove wall 61 is arc-shaped, and the radius R of the arc is 0.05mm to 0.10 mm.

In another embodiment of the present invention, there is also provided a glass cutting machine for fracture splitting, including any one of the fracturing cutter head 100, the cutter holder 200, and the cutter holder, wherein the cutter shaft 201 penetrates through the cutter shaft hole 3 of the fracturing cutter head 100, the fracturing cutter head 100 is mounted on the cutter holder 200, and the cutter holder 200 is mounted on the cutter holder. The holder here may be an integral holder 301, as shown in fig. 14 and 15; a removable cartridge 302 is also possible, as shown in fig. 12 and 13. When the cutter wheel is replaced, the integral cutter holder 301 needs to detach the whole cutter holder from the cutting machine and replace the cutter holder and the cutter wheel at the same time because the cutter holder 200 and the cutter wheel are fixed as a whole. After the cutter wheel is replaced, the cutter frame and the cutter wheel are installed on the cutting machine as a whole. When the cutter wheel is replaced, the detachable cutter holder 302 only needs to be directly detached from the cutter holder 200 at the top end of the detachable cutter holder 302 for replacement. By adopting the two cutter seats, the cutting cutter wheel on the cutting machine can be conveniently replaced by the fracturing cutter wheel, so that the cutting and fracturing procedures can be completed on the same operation platform.

The same and similar parts in the various embodiments in this specification may be referred to each other. The above-described embodiments of the present invention should not be construed as limiting the scope of the present invention.
