Description

Double-electrode external seam welder

Technical Field

The invention relates to the technical field of building material welding, in particular to a double-electrode external 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 rotating 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 rotating 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, as shown in fig. 1 and fig. 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 axis of the first through hole 210 may coincide with the axis of the faceplate 200.

The end plate assembly 300 includes a first end plate fixed in position with respect to the faceplate 200 and a second end plate movable in the axial direction with respect to the faceplate 200, and for example, the first end plate may be fixed by a clamping device such that the position of the first end plate 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, although the position of the clamping device is not limited thereto. The second end plate may be pulled by the cart so that the second end plate moves relative to the axial direction of the faceplate 200. The first end plate is provided with a plurality of positioning portions which can dispersedly position a plurality of weldment materials at the first end plate and can make the weldment materials move in the axis 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 can be dispersedly positioned at the positioning portions, and each weldment material corresponds to one positioning portion. The second end plate is provided with a plurality of second through holes 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 on the first end plate may be a through hole, for example, a second through hole that is the same as that on the second end plate is provided, or may be, for example, a clamping groove, and the positioning portion of the first end plate and the second through hole of the second end plate are not fastened, that is, after the weldment material is limited by the positioning portion, the weldment material may move along the axial direction of the faceplate 200. It should also be noted that the first and second end plates 310 may be replaced when the frame structure of weldment material is of different dimensions. 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 rotating mechanism 500 is disposed on the faceplate 200 and can rotate or move relative to the faceplate 200, and the rotating mechanism 500 fixes the welding material and the weldment material when moving or rotating relative to the faceplate 200. One end of the rotating mechanism 500 is provided with a first bonding pad 510 and a second bonding pad 520 opposite to each other, the first bonding pad 510 is electrically connected to the first electrode, and the second bonding pad 520 is electrically connected to the second electrode. The rotating mechanism 500 can drive the first welding disc 510 and the second welding disc 520 to move, and enable the first welding disc 510 to abut against a weldment material, and enable the second welding disc 520 to abut against the welding material against the weldment material.

The driving device includes a first driving element and a second driving element 610, wherein the first driving element drives the faceplate 200 to rotate, and the second driving element 610 drives the rotating mechanism 500 to move. The first drive element may be disposed on the base 100 and the second drive element 610 may be disposed on the faceplate 200 and rotate with the faceplate 200. The second driving element 610 may be a cylinder.

The working principle of the double-electrode external seam welder in the implementation is as follows: before the double-electrode external seam welder works, one end of a plurality of weldment materials is limited by a plurality of positioning parts of the first end plate and a plurality of second through holes on the second end plate, or sequentially penetrates through the first through hole 210 on the faceplate 200, the positioning part on the first end plate and the second through hole on the second end plate. 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 double-electrode external seam welder works, the first driving element works to enable the faceplate 200 to rotate around the axis of the faceplate 200, and the second end plate is driven to move along the axis of the faceplate 200 under the action of an external force, so that the welding material in the guide mechanism 400 is welded on the welding material in a spiral winding manner through the rotation of the faceplate 200 and the linear motion of the second end plate. When the first driving element drives the faceplate 200 to rotate, the second driving element 610 drives the rotating mechanism 500 to work, when the rotating mechanism 500 works, the first welding plate 510 can be abutted to a weldment material through rotating or moving relative to the faceplate 200, the second welding plate 520 is abutted to the welding material, and the second welding plate 520 can be abutted to the welding material. Since the first bonding pad 510 is electrically connected to the first electrode, that is, the first bonding pad 510 can transmit current to the weldment material, the second bonding pad 520 is electrically connected to the second electrode, that is, the second bonding pad 520 can transmit current to the weldment material. When the second welding disk 520 tightly presses the welding material against the weldment material, the resistance minimum current between the welding material and the contact point of the weldment material is the largest, the welding material or/and the weldment material are melted, and the welding material and the weldment material are welded. During the welding process, the positions of the first and

second welding pads

510 and 520 are kept still.

One of the first electrode and the second electrode is connected to a positive electrode of a power supply, and the other is connected to a negative electrode of the power supply. Which may be determined according to welding requirements. The current of the first electrode and the second electrode can also be obtained through electric brushes, for example, positive and negative electric brushes are arranged on the base 100, copper discs of the positive and negative electric brushes are fixed on the faceplate 200 and rotate with the faceplate 200, an external power supply supplies power to the positive and negative electric brushes, and the positive and negative electric brushes respectively transmit the obtained current to the first electrode or the second electrode through respective copper discs. 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 bonding pad 510 and the second bonding pad 520 are both external, the problem of suitability caused by difficult installation of the electrodes in the solution with the electrodes built in is avoided. Secondly, when the rotating mechanism 500 works, the weldment material and the welding material can be always electrified, that is, the scheme adopts the scheme of continuous electrified welding, so that the problem that the welding effect is poor and the electrode is damaged due to the fact that the current changes greatly in the welding process of the first welding disc 510 and the second welding disc 520 can be well avoided.

In order to enable the rotating mechanism 500 to better drive the first welding disk 510 and the second welding disk 520 to move, in an embodiment, referring to fig. 2, the rotating mechanism 500 includes a connecting rod assembly 530, wherein one end of the connecting rod assembly 530 is connected to a second driving element 610, the other end of the connecting rod assembly 530 is provided with the first welding disk 510 and the second welding disk 520, and the second driving element 610 drives the connecting rod assembly 530 to move. That is, in the present embodiment, the second driving element 610 is used as a power source, and the second connecting rod 532 converts the power of the second driving element 610 into a rotational motion or a curvilinear motion, so that the first welding disk 510 can abut against the weldment material, and the second welding disk 520 abuts against the weldment material.

Further, in an embodiment, referring to fig. 2 and 3, a first buffer mechanism 540 is disposed between the connecting rod assembly 530 and the second driving element 610, the connecting rod assembly 530 includes a first connecting rod 531 and a second connecting rod 532 disposed oppositely, wherein the first connecting rod 531 and the second connecting rod 532 are curved concave toward the end plate assembly 300, the first connecting rod 531 and the second connecting rod 532 are rotatably connected to the faceplate 200, one end of the first connecting rod 531 and one end of the second connecting rod 532 are respectively connected to the first buffer mechanism 540, the other end of the first connecting rod 531 is connected to the first welding plate 510, and the other end of the second connecting rod 532 is connected to the second welding plate 520.

In the embodiment, considering that the connecting rod assembly 530 brings the first welding disk 510 into contact with the weldment material, and the process of contacting the second welding disk 520 with the welding material is rigid contact, which easily causes the first welding disk 510 and the second welding disk 520 to be seriously worn during the operation, a first buffer mechanism 540 is directly arranged between the connecting rod assembly 530 and the second driving element 610, and when the first welding disk 510 and the second welding disk 520 are subjected to the action force of the welding material or the weldment material, the action force is transmitted to the first buffer mechanism 540 through the connecting rod assembly 530, so that the first welding disk 510 and the second welding disk 520 are momentarily away from the weldment material or the welding material.

In addition, it is considered that in order to prevent the first welding disk 510 and the second welding disk 520 from contacting each other, the first link 531 and the second link 532 in the link assembly 530 are connected to the first welding disk 510 and the second welding disk 520, respectively. The first link 531 and the second link 532 are formed in the shape of circular arcs, which is considered to facilitate that the first welding disk 510 abuts against the weldment material and the second welding disk 520 abuts against the welding material when the first link 531 and the second link 532 rotate relative to the faceplate 200. It should be noted that the rotational connection between the first link 531 and the second link 532 and the faceplate 200 may be realized by a rotational shaft.

Of course, it should be noted that the structure of the connecting rod assembly 530 is not limited to this, for example, the connecting rod assembly 530 may be configured as a linear type; the linkage assembly 530 may also be formed of a plurality of links for both linear and rotational movement.

In order to better fix the first welding disk 510 and the second welding disk 520 and further reduce the wear of the first welding disk 510, in an embodiment, referring to fig. 2 and 3, the first connecting rod 531 is further provided with a first mounting seat 550 and a second buffering mechanism 570, wherein the first mounting seat 550 is fixed on the first connecting rod 531, the second buffering mechanism 570 is fixed on the first mounting seat 550, and one end of the first welding disk 510 is pressed against one end of the second buffering mechanism 570; the second link 532 is provided with a second mount 560, and the second mount 560 fixes the second pad 520. In this embodiment, the first mounting seat 550 may be fixed to the first link 531 by welding or screwing, the second mounting seat 560 may be fixed to the second link 532 by welding or screwing, and the second damping mechanism 570 may be fixed to the first mounting seat 550 by welding or screwing. Because there is unevenness in the surface of weldment material, and the stroke of first welding disk 510 is fixed, consequently probably receive the effort of weldment material when first welding disk 510 supports and presses the weldment material, first welding disk 510 can support and press second buffer gear 570 this moment for first welding disk 510 can keep away from the weldment material, and then reduces the wearing and tearing of weldment material to first welding disk 510.

Further, in an embodiment, referring to fig. 4, the second buffer mechanism 570 includes an elastic member 571, a connecting rod 572, a first limiting portion 573 and a second limiting portion 574, the first mounting seat 550 includes a first abutting portion 551 and a second abutting portion 552, and each of the first abutting portion 551 and the second abutting portion 552 is provided with a through hole through which the connecting rod 572 passes. Specifically, the elastic member 571 is disposed between the first abutting portion 551 and the second abutting portion 552, the connecting rod 572 simultaneously passes through the through hole of the first abutting portion 551, the inner cavity of the elastic member 571 and the through hole of the second abutting portion 552, one end of the connecting rod 572 near the first abutting portion 551 is connected to the first limiting portion 573, the second limiting portion 574 is fixed to the connecting rod 572 and located between the second abutting portion 552 and the elastic member 571, the second limiting portion 574 presses one end of the elastic member 571, and the other end of the connecting rod 572 abuts against the first soldering tray 510. When the first bonding pad 510 is subjected to the action force of the bonding material, the first bonding pad 510 presses against the connecting rod 572, so that the second limiting portion 574 on the connecting rod 572 presses against the elastic member 571, and the elastic member 571 is compressed under the action of the second limiting portion 574, so that the first bonding pad 510 is far away from the bonding material. When the force applied to the first bonding pad 510 by the bonding material disappears, the elastic member 571 returns from the compressed state to the original state, in this process, the elastic member 571 drives the second position-limiting portion 574 on the connecting rod 572 to move, and the connecting rod 572 applies a force to the first bonding pad 510 during the moving process, so that the first bonding pad 510 approaches the bonding material. In this embodiment, the first limiting portion 573 and the second limiting portion 574 can jointly prevent the connecting rod 572 from falling off, and at the same time, the second limiting portion 574 can transmit the acting force on the connecting rod 572 to the elastic member 571, so that the first pad 510 can be away from the material of the weldment.

After the welding of the weldment material and the welding material are integrally completed, the unwelded welding material and the weldment material need to be separated. In one embodiment, referring to fig. 2, 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 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. 5, 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 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, 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.

It is considered that the welding discs are subject to great wear when pressed against the welding material. It is therefore necessary to detect the wear of the welding discs, in order to facilitate even their replacement. To this end, in one embodiment, referring to fig. 2, the faceplate 200 is provided with a detection module 630, and the detection module 630 is capable of detecting the wear of the first and

second pads

510 and 520. 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 position and a maximum distance threshold with the surface of the first bonding pad 510 and the surface of the second bonding pad 520, the distance measuring sensor measures the distance between the distance measuring sensor and the surface of the first bonding pad 510 and the surface of the second bonding pad 520 periodically or continuously, and when the distance between the distance measuring sensor and the surface of the first bonding pad 510 and the surface of the second bonding pad 520 is greater than or equal to the maximum distance threshold, the distance measuring sensor can directly display the result to an operator, so as to remind the operator to replace the first bonding pad 510 and the second bonding pad 520.

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 the chuck 200 may rotate continuously due to its inertia after the dual-electrode external seam welder stops working, the disassembly time of the weldment material is prolonged. For this purpose, in an embodiment, 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 direction of the faceplate 200, the driving device includes a fourth driving element, 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.

In order to realize the automatic control of the dual-electrode external seam welder, in an embodiment, referring to fig. 2, the base 100 is provided with a control module 650, wherein the control module 650 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 650 can control the first driving element, the second driving element 610 and the detection module 630 to work simultaneously when the dual-electrode external seam welder works, the first driving element drives the faceplate 200 to rotate, the second driving element 610 drives the rotation mechanism 500 to work, and the detection module 630 continuously or regularly obtains the wear information of the first welding plate 510 and the second welding plate 520; when the welding of the dual-electrode external seam welder is completed, the control module 650 controls the first driving element to stop working, the second driving element 610 drives the rotating mechanism 500 to return to the initial position, the third driving element drives the shearing mechanism 620 to shear the welding material, and the fourth driving element drives the turntable positioning mechanism 640 to work so that the faceplate 200 stops rotating. The control module 650 may 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, referring to fig. 2, the base 100 is further provided with a power module 660 and a control switch. When the control switch turns on the power module 660 and the circuit of the driving device, the driving device can work normally. 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.
