Technical Field

The invention relates to the technical field of building material welding, in particular to an end plate electrode type seam welder.

Background

In the field of construction, frames made of weldment material are often welded and fixed by welding material. For example, cage bars formed by steel bars are welded through spiral bars, so that the cage bar structure can be well fixed.

The existing seam welder mainly has two defects when welding a spiral rib and a steel bar: firstly, the seam welder with built-in electrodes has poor dimensional suitability for cage ribs. In reality, cage muscle size that the rod iron encloses is different, and before current built-in electrode seam welder work, need embed the inner chamber at the cage muscle with electrified electrode dish to the rod iron can be electrified when the welding. However, the electrode disc has a certain size, and when the size of the cage rib formed by the steel bars is smaller than that of the electrode disc, the motor disc cannot be placed in the cage rib. Therefore, the existing seam welder with built-in electrode has low size adaptability to the cage rib. Secondly, there is discontinuous welding in the external bipolar seam welder. The electrode and the steel bar of the existing double-electrode type seam welder are not continuously electrified, but current conduction is carried out at the welding point, the current change generated when the electrode and the steel bar are conducted is large due to the scheme, and then the electrode is greatly damaged, and meanwhile, the welding effect is also influenced.

The base 100 plays a supporting role, and the faceplate 200 can drive the guide mechanism 400 to rotate, so that the welding material contained in the guide mechanism 400 can be welded on the welding material in a winding manner; the end plate assembly 300 is used for positioning weldment material so that the weldment material can surround and form cage bars with different sizes on the end plate assembly 300; the sliding mechanism 500 can press the welding material against the weldment material to complete the welding process; the driving device can drive the faceplate 200 and the sliding mechanism 500 to work.

It should be noted that the welding material may be a spiral rib, the weldment material may be a steel bar, and the structural shape of the steel bar fixed on the end plate assembly 300 is a cage rib. The purpose of this scheme is fixed the cage muscle structure that the rod iron formed, is exactly to weld the spiral muscle on the rod iron to this structure that encloses into the rod iron is fixed.

Specifically, referring to fig. 1 and 2, the faceplate 200 may be rotatably disposed on the base 100 about its axis, the faceplate 200 may be provided with a first through hole 210 for allowing the elongated welding member material to pass through, and the axis of the first through hole 210 may coincide with the axis of the faceplate 200. For example, a driving shaft is provided at the axial center of the faceplate 200, and a driving element is connected with the driving shaft, thereby realizing the rotation of the faceplate 200.

The end plate assembly 300 includes a first end plate 310 fixed in position with respect to the faceplate 200 and a second end plate 320 movable in the axial direction of the faceplate 200, and the first end plate 310 may be fixed by, for example, a clamping device such that the position of the first end plate 310 with respect to the faceplate 200 is fixed, the clamping device may be located between the base 100 and the faceplate 200 or the clamping device may be located between the faceplate 200 and the first end plate 310, although the position of the clamping device is not limited thereto. The second end plate 320 may be pulled by the cart so that the second end plate 320 moves relative to the axial direction of the faceplate 200. The first end plate 310 is electrically connected with the first electrode, the first end plate 310 is provided with a plurality of positioning portions 311, and the plurality of positioning portions 311 can dispersedly position a plurality of weldment materials on the first end plate 310 and can enable the weldment materials to move along the axial direction of the faceplate 200. For example, when a plurality of weldment materials need to be welded and fixed to the frame structure, the plurality of weldment materials may be distributed and positioned in the positioning portions 311, and each weldment material corresponds to one positioning portion 311. The second end plate 320 is provided with a plurality of second through holes 321 for a plurality of weldment materials to pass through. When the end plate assembly 300 is circular, the axis of the end plate assembly 300 coincides with the axis of the faceplate 200. It should be noted that the positioning portion 311 on the first end plate 310 may be a through hole, for example, a second through hole 321 that is the same as the second end plate 320 is provided, or may also be a clamping slot, for example, the positioning portion 311 of the first end plate 310 and the second through hole of the second end plate 320 are not fixed, that is, after the welding member material is limited by the positioning portion 311, the welding member material may move along the axial direction of the faceplate 200. It should also be noted that the first end plate 310 and the second end plate 310 may be replaced when the frame structures made of weldment material are different in size.

The guide mechanism 400 is disposed on the faceplate 200, and the guide mechanism 400 includes a guide tube 410, wherein the guide tube 410 can accommodate a welding material, and the welding material can move in the guide tube 410.

The sliding mechanism 500 is disposed on the faceplate 200 and is movable, e.g., slidable or rotatable, relative to the faceplate 200, and the sliding mechanism 500 fixes the welding material and the weldment material when moving relative to the faceplate 200. One end of the sliding mechanism 500 is provided with a welding disc 510, the welding disc 510 is electrically connected to the second electrode, the sliding mechanism 500 can drive the welding disc 510 to move, for example, close to and away from the first end disc 310, and the sliding mechanism 500 can press the welding material against the welding material when moving. Note that, when the bonding pad 510 is charged, it does not charge the entire sliding mechanism 500, but only the bonding pad 510 itself is charged. For example, an insulating layer may be provided between the bonding pad 510 and the sliding mechanism 500, or an insulating material may be used for the sliding mechanism 500.

The driving means comprises a first driving element driving the faceplate 200 to rotate and a second driving element 610 driving the sliding mechanism 500 to move. The first driving element may be provided on the base 100 and the second driving element 610 may be provided on the faceplate 200.

The working principle of the end plate electrode type seam welder in the implementation is as follows: before the end plate electrode type seam welder works, one end of a plurality of weldment materials is limited by a plurality of positioning parts 311 on the first end plate 310 and a plurality of second through holes on the second end plate 320, or sequentially passes through the first through holes 210 on the faceplate 200, a plurality of positioning parts 311 on the first end plate 310 and a plurality of second through holes 321 on the second end plate 320. After the weldment material passes through the second through holes 321 of the second end plate 320, one end of the plurality of weldment materials is subjected to upsetting treatment, i.e., the weldment material is prevented from being separated from the second end plate 320. One end of the welding material passes through the guide tube 410 of the guide mechanism 400 and is welded to the welding material in advance, so that when the welding material moves along the axial direction of the faceplate 200 and the faceplate 200 rotates, the welding material can be continuously moved out of the guide mechanism 400, and the faceplate 200 rotates due to the linear motion of the welding material, so that the welding material can be welded and fixed to the welding material in a spiral winding manner.

Specifically, when the end plate electrode type seam welder works, the first driving element works to enable the faceplate 200 to rotate around the axis of the faceplate, the second end plate 320 drives the welding piece material to move along the axis of the faceplate 200 under the action of external force, and the welding material in the guide mechanism 400 is welded on the welding piece material in a spiral winding mode through the rotary motion of the faceplate 200 and the linear motion of the second end plate 320.

When the first driving element drives the faceplate 200 to rotate, the second driving element 610 drives the sliding mechanism 500 to work, and the welding plate 510 can be driven to move when the sliding mechanism 500 works. The welding disk 510 presses the welding material removed from the guide tube 410 against the weldment material, when the welding disk 510 presses against the welding material, the weldment material is electrified by the first electrode through the first end plate 310, the welding material is electrified by the second electrode through the welding disk 510, the first electrode and the second electrode are opposite positive electrodes or negative electrodes, the resistance between the welding material and the contact point of the weldment material is minimum and the current is maximum, the welding material or the weldment material is melted by the current, and the welding material can be welded on the weldment material. During the welding process, the position of the welding disk 510 remains stationary and the welding disk 510 is continuously pressed against the welding material.

It should be noted that one of the first electrode and the second electrode is connected to the positive electrode of the power source, and the other is connected to the negative electrode of the power source, which can be determined according to the welding requirements. The current of the first electrode and the second electrode can also be obtained through electric brushes, for example, a positive electric brush and a negative electric brush are arranged on the base 100, copper discs of the positive electric brush and the negative electric brush are fixed on the faceplate 200 and rotate with the faceplate 200, an external power supply supplies power to the positive electric brush and the negative electric brush, and the positive electric brush and the negative electric brush respectively transmit the current to the first electrode or the second electrode through the respective copper discs after obtaining the current. The advantage of this design is that the wire connected to the first electrode or the second electrode can be better prevented from winding during rotation.

In this embodiment, since the first end plate 310 is directly electrically connected to the first electrode, the first end plate 310 is integrally charged, thereby avoiding the problem of adaptability caused by the difficulty in mounting the electrode in the electrode-embedded scheme. Secondly, since the first end plate 310 is always charged, the steel bar is always charged, and the welding disc 510 can press against the welding material under the control of the sliding mechanism 500, so that the welding material is also always charged. That is, the scheme of continuous live welding is adopted in the scheme, so that the problem that the welding effect is poor and the electrode is damaged due to large current change in the welding process of the first end plate 310 and the welding disc 510 can be better avoided.

To better facilitate the rotation of the welding plate 510 by the sliding mechanism 500, in one embodiment, referring to fig. 3, the sliding mechanism 500 includes a first link 520 and a second link 530, wherein the first link 520 includes opposite ends a1 and a2, and the second link 530 includes opposite ends B1 and B2. The a1 end of the first link 520 is connected to the second driving element 610, the a2 end of the first link 520 is connected to the B1 end of the second link 530, and the B2 end of the second link 530 is fixedly provided with the welding disk 510. When the second driving element 610 drives the first link 520 to move, the first link 520 drives the second link 530 to move, so that the welding disk 510 can press the welding material against the weldment material. That is, the present embodiment employs a link mechanism to control the movement of the bonding pad 510. It should be noted that, when the first link 520 reciprocates, the end B1 of the second link 530 can rotate relative to the end a2 of the first link 520; or the a2 end of the first link 520 may push the B1 end of the second link 530 to move when the first link 520 reciprocates. In this embodiment, the movement of the welding disk 510 can be well controlled by the link mechanism, so that the welding disk 510 can tightly press against the welding material.

Further, in an embodiment, referring to fig. 3, the first link 520 extends along a first direction on the faceplate 200, the first direction is a direction indicated by an arrow a in fig. 3, and the second driving element 610 is capable of driving the first link 520 to move back and forth on the faceplate 200 along the first direction. The end A2 of the first link 520 is fixedly connected with the end B1 of the second link 530, a pulley is arranged on the side of the second link 530 facing the faceplate, a slide rail 220 is arranged along the faceplate 200 in the first direction, and the pulley on the second link 530 is matched with the slide rail 220 on the faceplate 200. When the second driving element 610 drives the first link to reciprocate, the first link 520 can drive the second link 530 to reciprocate in the first direction, and the welding disc 510 at the end B2 of the second link 520 is close to the welding material and presses the welding material against the weldment material. That is, in the present embodiment, the first link 520 and the second link 530 both move linearly, and the first link 520 can drive the second link 530 to move under the driving of the first driving element 610, so that the welding disc 510 on the second link 530 approaches and leaves the welding material. Of course, in order to ensure the smoothness of the second link 530 moving along the first direction, a plurality of sliding rails 220 may be disposed on the faceplate 200, and a plurality of pulleys engaged with the plurality of sliding rails 220 may be disposed on the second link 530.

In another embodiment, referring to fig. 3, the first link 520 and the second link 530 of the sliding mechanism 500 are both disposed on the faceplate 200, wherein the first link 520 extends along a first direction, and the second driving element 610 drives the first link 520 to reciprocate along the first direction on the faceplate 200; the end a2 of the first link 520 is rotatably connected to the end B1 of the second link 530, and when the first link 520 mechanism moves back and forth along the first direction, the end B1 of the second link 530 rotates relative to the end a1 of the first link 520, and the welding disk 510 of the second link 530 rotates toward the direction close to or away from the first end plate 310, so that the welding disk 510 presses the welding material against the weldment material. That is, in the present embodiment, the linear motion of the first link 520 drives the second link 530 to rotate, so that the welding disk 510 approaches and leaves the first end plate 310.

Considering that the welding pad 510 is pressed against the welding material, when the feeding stroke of the welding pad 510 is determined, the force between the welding pad 510 and the welding material may be too large to cause the welding pad 510 to be seriously worn due to the unevenness of the surface of the welding material. For this purpose, in an embodiment, referring to fig. 3, the end B2 of the second link 530 is provided with a mounting seat 540 and a buffer mechanism 550, wherein the mounting seat 540 is fixedly connected with the end B2 of the second link 530, the buffer mechanism 550 is arranged on the mounting seat 540, the welding disk 510 abuts against one end of the buffer mechanism 550, and when the welding disk 510 is subjected to the force of the welding material, the welding disk 510 abuts against the buffer mechanism 550. That is, when the pad 510 is subjected to a large force of the welding material, the pad 510 is moved away from the welding material by pressing against the buffer mechanism 550. The buffer mechanism 550 may be a spring, one end of which is fixed to the mounting seat 540 and the other end of which is connected to the welding plate 510. Of course, it should be understood that an insulating structure is provided between the bonding pad 510 and the spring.

After the weldment material and the welding material are integrally welded, the unwelded welding material and the weldment material need to be separated. In one embodiment, referring to fig. 3, the faceplate 200 is provided with a shearing mechanism 620, and the driving device comprises a third driving element 623, wherein the third driving element 623 can be fixed on the base 100, and the third driving element 623 drives the shearing mechanism 620 to move and shear the welding material contained in the guiding mechanism 400. That is, the cutting mechanism 620 can cut off the unused welding material.

Further, in an embodiment, referring to fig. 3, the cutting mechanism 620 includes an expansion portion 621 and a cutting portion 622, wherein the expansion portion 621 extends toward the axis of the first end plate 310 and corresponds to the outlet of the guide tube 410, one end of the expansion portion 621 is connected to the third driving element 623, and the other end is connected to the cutting portion 622. When the expansion portion 621 moves in the axial direction of the first end plate 310, the welding material not used at this time corresponds to the cutting portion 622, and the cutting portion 622 can cut the welding material. The telescopic portion 621 may be a shaft or a lead screw, and the cutting portion 622 may be a blade or a hydraulic cutting nipper.

Consider that the weld pad 510 experiences greater wear when pressed against the weld material. It is therefore desirable to detect wear of the weld plate 510 to facilitate its replacement in a timely manner. To this end, in one embodiment, referring to fig. 3, the faceplate 200 is provided with a detection module 630, and the detection module 630 is capable of detecting wear of the bonding pad 510. For example, the detection module 630 may be a distance measuring sensor, in an initial case, the distance measuring sensor is fixed on the faceplate 200, and sets an initial distance between the distance measuring sensor and the surface of the soldering pad 510 and a maximum distance threshold, the distance measuring sensor measures the distance between the distance measuring sensor and the surface of the soldering pad 510 periodically or continuously, and when the distance between the distance measuring sensor and the surface of the soldering pad 510 is greater than or equal to the set maximum distance threshold, the distance measuring sensor can directly display the result to an operator, so as to remind the operator to replace the soldering pad 510.

In order to better support the faceplate 200 and facilitate the movement of the welding member material, in this embodiment, referring to fig. 1, the base 100 includes a base 110 and a support 120, wherein the support 120 is perpendicular to the base 110. The support portion 120 is provided with a third through hole, the faceplate 200 is fixed to the support portion 120, and the first through hole 210 of the faceplate 200 is concentric with the third through hole of the support portion 120. In the actual welding process, the welding member is generally a long steel bar, and in order to facilitate the steel bar to move along the length direction, the support 120 perpendicular to the base 110 is used to fix the faceplate 200. After the steel bar passes through the third through hole of the support part 120 and the first through hole 210 of the faceplate 200, the steel bar is oriented perpendicular to the support part 120 and the faceplate 200, so that the steel bar can move in an extending manner along the length direction of the steel bar.

Considering that after the end plate seam welder stops working, the faceplate 200 may continue to rotate due to its inertia, thus prolonging the time for removing the weldment material. For this purpose, in an embodiment, referring to fig. 2, the supporting portion 120 of the base 100 is provided with a turntable positioning mechanism 640, the turntable positioning mechanism 640 extends toward the axial center of the faceplate 200, the driving device includes a fourth driving element, the fourth driving element can be fixed on the base 100, the fourth driving element drives the turntable positioning mechanism 640 to move back and forth, and the turntable positioning mechanism 640 can abut against the outer edge of the faceplate 200, so as to stop the rotation of the faceplate 200 more quickly.

In order to realize the automatic control of the end plate electrode type seam welder, in an embodiment, referring to fig. 2, the base 100 is provided with a control module 650, wherein the control module is electrically connected to the first driving element, the second driving element 610, the third driving element 623, the fourth driving element and the detection module 630. The control module can control the first driving element, the second driving element 610 and the detection module 630 to work simultaneously when the end plate type seam welder works, the first driving element drives the faceplate 200 to rotate, the second driving element 610 drives the sliding mechanism 500 to work, and the detection module 630 acquires wear information of the welding plate 510 continuously or regularly; when the end plate type seam welder finishes welding, the control module controls the first driving element to stop working, the second driving element 610 drives the sliding mechanism 500 to return to the initial position, the third driving element drives the shearing mechanism 620 to shear welding materials, and the fourth driving element drives the turntable positioning mechanism 640 to work so that the faceplate 200 stops rotating. The control module can be a single chip microcomputer driving unit or a PLC control unit.

In order to enable the driving device to obtain driving power, in one embodiment, the base 100 is further provided with a power module 660 and a control switch. The power module 660 may supply power to the first electrode, the second electrode, and the driving device. For example, when the power module 660 supplies power to the driving device through the control switch, the driving device can operate normally when the control switch conducts the circuit between the power module 660 and the driving device. For example, under the control of a piston rod of the air cylinder, when the piston rod is abutted to the control switch, the power module 660 is conducted with a circuit of the driving device; when the piston rod is far away from the control switch, the power module 660 is disconnected from the circuit of the driving device.
