Description

Technical Field

[0001] The invention belongs to the technical field of welding devices, in particular to a rolling welding electrode for high-frequency resistance welding. Background Art

[0002] Resistance welding uses conduction feeding. High-frequency current is passed through two contact heads (electrodes). The skin effect and proximity effect of high-frequency current are utilized to concentrate the current at the edge of the tube to be welded. The tube is then quickly heated to the welding temperature. Pressure welding is then performed under the action of squeeze rollers. Resistance welding has the advantages of high thermal efficiency and low energy consumption.

[0003] Patent publication number CN209021414U discloses a rolling welding electrode for high-frequency resistance welding, which primarily comprises an electrode roller, a positive terminal, a negative terminal, a coupling plate, and a drive shaft. The electrode roller is a rotating body with a certain curvature, with a larger diameter at each end than in the middle. The electrode roller has a through-hole in its center and is fixed to the coupling plate via a drive shaft. The coupling plate of the rolling welding electrode features three electrode rollers of gradually decreasing size and similar structure, evenly spaced. The two coupling plates connect the positive and negative terminals, respectively. The electrode rollers are larger near the apex of the opening angle, and their volume decreases as the distance from the apex increases. The rolling welding electrode exhibits low friction with the weld pipe, significantly reducing damage to the pipe surface and the electrode, thereby improving pipe quality and the electrode's service life. The use of electrode rollers of varying sizes concentrates heating at the apex of the V-angle, resulting in more efficient heating of the weld pipe.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Rolling welding electrodes are used, which have low friction with the pipe, significantly reducing damage to the pipe surface and the electrode. However, when welding a large number of pipes, workers are required to manually position each pipe individually for welding, which is cumbersome and labor-intensive. Furthermore, when a robot is used to position the pipes, the pipes may be stacked irregularly, making it difficult for the robot to move them along the pre-set path, thus affecting loading efficiency.

[0020] 1. The present invention discloses a rolling welding electrode for high-frequency resistance welding. Using a feeding assembly, multiple welded pipes can be sequentially positioned for welding, eliminating the need for workers to manually position each pipe individually for welding. This method is more convenient and reduces labor intensity. Furthermore, compared to using a robotic arm to position welded pipes, this method allows multiple, chaotically stacked pipes to be neatly arranged and moved to the welding position at a uniform angle. This avoids the situation where the robotic arm has difficulty in picking up the pipes according to the pre-set movement path due to the chaotic arrangement of the pipes, thus affecting loading efficiency.

[0022] 3. The rolling welding electrode for high-frequency resistance welding described in the present invention has the following characteristics: when multiple welded pipes converge into an arrangement channel, the push plates on both sides slide back and forth laterally, pushing the welded pipes stuck between the two channel plates, prompting the welded pipes to move, thereby avoiding the situation where the welded pipes are stuck at the channel opening when converging into the arrangement channel, and ensuring the smooth progress of subsequent welding work.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In this embodiment, Figure 1-Figure 5 、 Figure 10 As shown, one side of the slider 19 is threadedly connected to a threaded rod 3 22, both ends of the threaded rod 3 22 are rotatably set on the base 1, and one side of the upper end surface of the base 1 is fixedly connected to a motor 4 23, and the output end of the motor 4 23 is fixedly connected to one end of the threaded rod 3 22.

[0039] One side of the lower end of the sleeve 2 47 is threadedly connected to the threaded rod 20, and both ends of the threaded rod 20 are rotatably set on the slider 19. One side of the upper end surface of the slider 19 is fixedly connected to the motor 3 21, and the output end of the motor 3 21 is fixedly connected to one end of the threaded rod 20. One side of the sleeve 2 47 is fixedly connected to the electric push rod 24, and the piston end of the electric push rod 24 is fixedly connected to one end of the telescopic rod 25.

[0040] The lower end of the sleeve 10 is threadedly connected to a bidirectional threaded rod 11, and both ends of the bidirectional threaded rod 11 are rotatably set on the base 1. One side of the upper end surface of the base 1 is fixedly connected to a motor 10 49, and the output end of the motor 10 49 is fixedly connected to one end of the bidirectional threaded rod 11. One side of the sleeve 10 is fixedly connected to an electric push rod 15, and the piston end of the electric push rod 15 is fixedly connected to one end of the telescopic rod 14.

[0041] One side of the upper end of the channel plate 3 is threadedly connected to a bidirectional threaded rod three 41, and both ends of the bidirectional threaded rod three 41 are rotatably set on the frame body 1 4. One side of the upper end of the frame body 1 4 is fixedly connected to a motor nine 42, and the output end of the motor nine 42 is fixedly connected to one end of the bidirectional threaded rod three 41. One side of the upper end of the channel plate 3 is fixedly connected to a cylinder two 45, and the piston end of the cylinder two 45 is fixedly connected to the upper end of the baffle 46.

[0042] Specifically, existing technologies use rolling welding electrodes, which have low friction with the pipe, significantly reducing damage to the pipe surface and the electrode. However, when welding a large number of pipes, workers are required to manually position each pipe individually for welding, which is cumbersome and labor-intensive. Furthermore, when using a robotic arm to position the pipes, the pipes may be stacked irregularly, making it difficult for the robotic arm to move them along the pre-set path, thus affecting loading efficiency.

[0043] Therefore, to address the aforementioned issues, this embodiment is designed for use with the same batch of welded pipes of the same specifications. Based on the pipe diameter, motor nine (42) drives bidirectional threaded rod three (41) to rotate, adjusting the spacing between the two channel plates (3) to equal the pipe diameter. As the spacing between the two channel plates (3) changes, baffle plate (46) and telescopic plate (12) also slide relative to each other. Cylinder two (45) then drives baffle plate (46) up and down, adjusting the distance between the bottom of baffle plate (46), telescopic plate (12), and the surface of conveyor belt (2) to a distance greater than the diameter of one pipe but less than the diameter of two pipes.

[0044] Then put multiple welded pipes onto the conveyor belt 2, and then drive the conveyor belt 2 to operate. Under the operation of the conveyor belt 2, multiple welded pipes gather at the narrowest distance between the two channel plates 3. Since the two channel plates 3 cooperate with each other to form an arrangement channel, and the channel opening can only pass one welded pipe at a time, multiple welded pipes passing through the channel opening will be arranged and placed in the arrangement channel.

[0045] After the end of a welded pipe passes over the end of conveyor belt 2, electric push rod 15 drives telescopic rod 14 to slide within sleeve 10, adjusting the height of squeeze roller 13 according to the pipe's diameter. Simultaneously, motor 10 49 drives bidirectional threaded rod 11 to rotate, adjusting the spacing between the two squeeze rollers 13 so that the pipe can be clamped between them. Similarly, electric push rod 2 24 drives telescopic rod 2 25 to slide within sleeve 2 47, adjusting the height of electrode roller 26. Motor 3 21 drives threaded rod 2 20 to rotate, causing sleeve 2 47 to move laterally, adjusting the position of electrode roller 26 so that it is positioned at the desired weld location. With the pipe extruded and formed by squeeze roller 13 and the cooperation of electrode roller 26, welding can then be performed. Simultaneously, motor 4 23 drives threaded rod 3 22 to rotate, and slider 19 slides on base 1, adjusting the horizontal position of electrode roller 26 to facilitate welding at different locations on the pipe.

[0046] When a welded pipe is welded, it is driven to fall from between the two squeezing rollers 13, and a container can be placed on the base 1 to collect the welded pipe. Then, the above operation is repeated, and multiple welded pipes can be welded in sequence, thereby eliminating the process of workers manually placing multiple welded pipes one by one in the designated position for welding. It is more convenient and reduces the intensity of workers' labor. In addition, compared with the method of using a robot to place the welded pipe in a designated position, this method can arrange multiple messy stacked welded pipes neatly and move them to the welding position at a uniform angle, avoiding the situation where the welded pipes are relatively messy and the robot is difficult to pick up the welded pipes according to the preset moving path, thereby affecting the loading efficiency.

[0047] In this embodiment, Figure 6-Figure 9 As shown, the base 1 is also provided with an identification adjustment component;

[0048] The identification adjustment component includes a guide rail 7 slidably connected to one side of the upper end surface of the base 1, a lifting block 31 is slidably connected to the inner side of the guide rail 7, a turntable 33 is rotatably provided on one side of the lifting block 31, a threaded block 37 is slidably connected to the slide groove of the turntable 33, a detection column 40 is slidably connected to one side of the threaded block 37, and a pressure sensor 39 is provided at one end of the detection column 40; one side of the upper end surface of the base 1 is fixedly connected to a frame body 2 16, the middle part of the upper end surface of the frame body 2 16 is fixedly connected to a cylinder 1 5, the piston end of the cylinder 1 5 is fixedly connected to a lifting plate 6, a guide rail 2 18 is rotatably provided in the middle part of the lower end surface of the lifting plate 6, and clamping blocks 29 are slidably connected to both ends of the inner side of the guide rail 2 18.

[0049] The lower end of the guide rail 7 is threadedly connected to a threaded rod 8, and both ends of the threaded rod 8 are rotatably set on the base 1. A motor 9 is fixedly connected to one side of the upper end surface of the base 1, and the output end of the motor 9 is fixedly connected to one end of the threaded rod 8. One end of the lifting block 31 is threadedly connected to a threaded rod 5 36, and both ends of the threaded rod 5 36 are rotatably set on the guide rail 7. The upper end of the guide rail 7 is fixedly connected to a motor 6 30, and the output end of the motor 6 30 is fixedly connected to one end of the threaded rod 5 36. A motor 7 32 is fixedly connected to one side of the lifting block 31, and the output end of the motor 7 32 is fixedly connected to one side of the turntable 33.

[0050] A threaded rod four 35 is threadedly connected to one side of the threaded block 37, and both ends of the threaded rod four 35 are rotatably set on the turntable 33. A motor eight 34 is fixedly connected to one side of the turntable 33, and the output end of the motor eight 34 is fixedly connected to one end of the threaded rod four 35. A spring 38 is sleeved on one side of the detection column 40, and one end of the spring 38 is fixedly connected to the threaded block 37, and the other end is fixedly connected to the end of the detection column 40.

[0051] The upper end surface of the lifting plate 6 is fixedly connected to the motor 2 17, the output end of the motor 2 17 is fixedly connected to the guide rail 2 18, the upper end of the clamping block 29 is threadedly connected to the bidirectional threaded rod 28, both ends of the bidirectional threaded rod 28 are rotatably set on the guide rail 2 18, one end of the guide rail 2 18 is fixedly connected to the motor 5 27, and the output end of the motor 5 27 is fixedly connected to one end of the bidirectional threaded rod 28.

[0052] Specifically, in the above embodiment, although the welded pipes can be placed one by one at the welding location, the weld seams of the welded pipes are V-shaped. When the welded pipes arrive at the welding location, the weld seams thereof are randomly oriented. This makes it difficult for the electrode rolling element 26 to weld along the preset path, thereby affecting the normal progress of the welding operation.

[0053] Therefore, in order to solve the above problems, when the present embodiment is in use, when a welded pipe reaches the welding position, the motor 6 30 is used to drive the threaded rod 5 36 to rotate according to the diameter of the welded pipe, and the height of the turntable 33 is adjusted so that the axis of the turntable 33 coincides with the axis of the welded pipe. In addition, the motor 8 34 is used to drive the threaded rod 4 35 to rotate, and the distance between the detection column 40 and the axis of the turntable 33 is adjusted so that the detection column 40 is aligned with the cross section of the welded pipe. Then, the motor 1 9 is used to drive the threaded rod 1 8 to rotate so that the detection column 40 is close to the cross section of the welded pipe until the detection column 40 and the welded pipe cross section are squeezed and the detection column 40 is retracted into the threaded block 37. Then, the turntable 33 is driven to rotate, and the detection column 40 moves along the cross section of the welded pipe. When the detection column 40 moves to the weld seam of the welded pipe, the detection column 40 will be reset by the spring 38. At this time, the detection column 40 continues to make a circular motion, and the weld seam will rotate due to the abutment between the detection column 40 and the weld seam. After the detection column 40 rotates one circle, the weld seam of the welded pipe faces upward. Therefore, no matter what angle the weld seam of the welded pipe in the welding area is at, the welded pipe will be rotated to a fixed angle after the detection column 40 rotates one circle. If the weld seam of the welded pipe is on the side away from the detection column 40, then after the detection column 40 rotates one circle, the pressure sensor 39 will continue to detect pressure due to its constant contact with the cross section of the welded pipe. At this time, the cylinder 1 5 drives the lifting plate 6 to descend, so that the two clamps 29 are on both sides of the welded pipe, and then the motor 5 27 drives the two-way threaded rod 2 28 to rotate, so that the two clamps 29 are close to each other, clamping the welded pipe, and then driving the welded pipe to rise, and the motor 2 17 drives the guide rail 2 18 to rotate, so that the welded pipe rotates 180 degrees, and then repeats the above operation again, so that the welded pipe rotates to a fixed angle, and the subsequent welding work can be carried out again. This avoids the situation where when the welded pipe arrives at the welding point, its weld seam is randomly oriented, and the electrode rolling body 26 is difficult to weld according to the preset path, thereby affecting the normal progress of the welding work.

[0054] In this embodiment, Figure 5 and Figure 10 As shown, a push plate 44 is inserted and slidably connected to one side of the channel plate 3, a cylinder three 43 is fixedly connected to one side of the channel plate 3, and the piston end of the cylinder three 43 is fixedly connected to one side of the push plate 44.

[0055] Specifically, in the above embodiment, although multiple welded pipes can be arranged in an array for subsequent welding, when the welded pipes converge into the arrangement channel, they are prone to getting stuck at the channel opening, thereby affecting the smooth progress of subsequent welding work.

[0056] Therefore, in order to solve the above problems, when the present embodiment is in use, when multiple welded pipes converge to the arrangement channel, the cylinders 3 43 on both sides are started in turn, and drive the push plate 44 to slide back and forth laterally, pushing the welded pipe stuck between the two channel plates 3, prompting the welded pipe to move, thereby avoiding the situation where the welded pipe is stuck at the channel mouth when converging to the arrangement channel, and ensuring the smooth progress of subsequent welding work.

[0057] Working principle: According to the diameter of the welded pipe, the motor 9 42 drives the two-way threaded rod 3 41 to rotate, adjusting the distance between the two channel plates 3 so that the distance is equal to the diameter of the welded pipe. When the distance between the two channel plates 3 changes, the baffle 46 and the telescopic plate 12 also slide relative to each other. Then the cylinder 2 45 drives the baffle 46 up and down, adjusting the distance between the baffle 46 and the bottom of the telescopic plate 12 and the surface of the conveyor belt 2 so that the distance is greater than the diameter of one welded pipe and less than the diameter of two welded pipes. Then, multiple welded pipes are uniformly placed on the conveyor belt 2, and then the conveyor belt 2 is driven to operate. Under the operation of the conveyor belt 2, multiple welded pipes converge at the narrowest distance between the two channel plates 3. Since the two channel plates 3 cooperate with each other to form an arrangement channel, and the channel opening can only pass one welded pipe at a time, multiple welded pipes passing through the channel opening will be arranged and placed in the arrangement channel.

[0058] After the end of a welded pipe passes over the end of conveyor belt 2, electric push rod 15 drives telescopic rod 14 to slide within sleeve 10, adjusting the height of squeeze roller 13 according to the pipe's diameter. Simultaneously, motor 10 49 drives bidirectional threaded rod 11 to rotate, adjusting the spacing between the two squeeze rollers 13 so that the pipe can be clamped between them. Similarly, electric push rod 2 24 drives telescopic rod 2 25 to slide within sleeve 2 47, adjusting the height of electrode roller 26. Motor 3 21 drives threaded rod 2 20 to rotate, causing sleeve 2 47 to move laterally, adjusting the position of electrode roller 26 so that it is positioned at the desired weld location. With the pipe extruded and formed by squeeze roller 13 and the cooperation of electrode roller 26, welding can then be performed. Simultaneously, motor 4 23 drives threaded rod 3 22 to rotate, and slider 19 slides on base 1, adjusting the horizontal position of electrode roller 26 to facilitate welding at different locations on the pipe.

[0059] When a welded pipe is welded, it is driven to fall from between the two squeezing rollers 13, and a container can be placed on the base 1 to collect the welded pipe. Then, the above operation is repeated, and multiple welded pipes can be welded in sequence, thereby eliminating the process of workers manually placing multiple welded pipes one by one in the designated position for welding. It is more convenient and reduces the intensity of workers' labor. In addition, compared with the method of using a robot to place the welded pipe in a designated position, this method can arrange multiple messy stacked welded pipes neatly and move them to the welding position at a uniform angle, avoiding the situation where the welded pipes are relatively messy and the robot is difficult to pick up the welded pipes according to the preset moving path, thereby affecting the loading efficiency. When a welded pipe reaches the welding position, according to the diameter of the welded pipe, the motor 6 30 is used to drive the threaded rod 5 36 to rotate, and the height of the turntable 33 is adjusted so that the axis of the turntable 33 coincides with the axis of the welded pipe. In addition, the motor 8 34 is used to drive the threaded rod 4 35 to rotate, and the distance between the detection column 40 and the axis of the turntable 33 is adjusted so that the detection column 40 is aligned with the cross section of the welded pipe. Then, the motor 19 is used to drive the threaded rod 18 to rotate so that the detection column 40 is close to the cross section of the welded pipe until the detection column 40 and the welded pipe cross section are squeezed and the detection column 40 is retracted into the threaded block 37. Then, the turntable 33 is driven to rotate, and the detection column 40 moves along the cross section of the welded pipe. When the detection column 40 moves to the weld seam of the welded pipe, the detection column 40 will be reset by the spring 38. At this time, the detection column 40 continues to make a circular motion, and the weld seam will rotate because the detection column 40 and the weld seam are against each other. After the detection column 40 rotates one circle, the weld seam of the welded pipe faces upward. Therefore, no matter what angle the weld seam of the welded pipe in the welding area is at, the welded pipe will be rotated to a fixed angle after the detection column 40 rotates one circle. If the weld seam of the welded pipe is on the side away from the detection column 40, then after the detection column 40 rotates one circle, the pressure sensor 39 will continue to detect pressure due to its constant contact with the cross section of the welded pipe. At this time, the cylinder 1 5 drives the lifting plate 6 to descend, so that the two clamps 29 are on both sides of the welded pipe, and then the motor 5 27 drives the two-way threaded rod 2 28 to rotate, so that the two clamps 29 are close to each other, clamping the welded pipe, and then driving the welded pipe to rise, and the motor 2 17 drives the guide rail 2 18 to rotate, so that the welded pipe rotates 180 degrees, and then repeats the above operation again, so that the welded pipe rotates to a fixed angle, and the subsequent welding work can be carried out again. This avoids the situation where when the welded pipe arrives at the welding point, its weld seam is randomly oriented, and the electrode rolling body 26 is difficult to weld according to the preset path, thereby affecting the normal progress of the welding work. When multiple welded pipes converge into the arrangement channel, the air cylinders 43 on both sides are started in turn, and drive the push plate 44 to slide back and forth laterally, pushing the welded pipes stuck between the two channel plates 3, prompting the welded pipes to move, thereby avoiding the situation where the welded pipes are stuck at the channel mouth when converging into the arrangement channel, and ensuring the smooth progress of subsequent welding work.
