Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to a plasma welding device for producing aluminum wire cables. Background Art

[0002] During the production process, aluminum conductors need to be reliably connected to the terminals by welding. Welding can ensure stable conductivity and reduce contact resistance, avoiding poor contact or heating problems caused by loose mechanical crimping. Plasma welding quickly melts aluminum conductors and aluminum welding wires through high-energy plasma arcs, and uses inert gas to protect the molten pool to form a dense weld. Its advantages are concentrated heat input, small heat-affected zone, and precision aluminum welding. Before welding aluminum conductors to terminals, the insulation needs to be stripped in advance, so that an oxide film is easily formed on the surface of the aluminum conductor during storage. The oxide film has high insulation properties, and is prone to molten pool inclusions and pores during welding, which significantly reduces conductivity and connection reliability. At the same time, after the insulation is stripped, the wires will be tied with disposable cable ties, so that the metal wires of the wires can fit tightly, avoiding the metal wires from curling up, facilitating insertion with the terminals, and reducing the oxidation of the metal wires inside the wires.

[0003] In the prior art, during the welding process of aluminum wires, the oxide layer needs to be removed manually. However, due to the influence of the cable tie, the oxide layer on the surface of part of the wire cannot be completely removed, and there are dead corners, which will affect the conductive effect. At the same time, the cable tie needs to be manually removed during the insertion and connection of the aluminum wire and the terminal. The whole process is time-consuming and labor-intensive, which affects the welding efficiency of the wire. Summary of the invention

[0016] The present invention has the following beneficial effects:

[0017] 1. In the plasma welding device for aluminum wire and cable production, the second jaw can clamp the terminal, and the first jaw and the clamping seat cooperate to clamp the cable body. The first electric push rod can indirectly drive the cable body to move horizontally and insert it into the terminal. At the same time, the servo motor can drive the terminal to twist left and right, so that the terminal is inserted into the cable body in a twisting manner, thereby reducing the frictional resistance and making the insertion process smoother.

When the servo motor rotates reciprocally, the purpose of the L-shaped abutting rod and the L-shaped abutting frame abutting reciprocally can be achieved. Through the cooperation of the second abutting wedge block, the second abutting rod and the first abutting wedge block, the two wire brush blocks automatically rotate reciprocally on the two cleaning seats, so that the cable body can automatically polish the oxide layer while moving, greatly improving the efficiency of oxide layer removal and the welding quality can be improved;

[0018] When the wire brush block rotates on the cleaning seat, the purpose of the wire brush block driving the guide post to abut against the first abutting rod fixed on the cutter can be achieved, prompting the cutter to move horizontally and automatically cut the cable tie tied to the cable body, so that the covered surface of the cable body can be exposed for polishing.

[0019] 2. In the plasma welding device for aluminum wire and cable production, through the material receiving groove opened on the welding table, the cut cable ties can conveniently fall into the inside of the welding table for centralized treatment. When the L-shaped abutting frame drives the U-shaped abutting block to move reciprocally, the purpose of the U-shaped abutting block abutting against the lower ends of the two push plates at the same time can be achieved, prompting the two push plates to slide on the third guide rod and approach each other, facilitating the push plates to automatically gather the cable ties that fall on the surface of the welding table and push them into the material receiving groove, which can reduce the situation of manual frequent shutdown for cleaning cable ties and significantly improve the continuity of welding operations.

[0020] 3. In the plasma welding device for aluminum wire and cable production, when the second electric push rod drives the mounting frame to continue moving downward, the purpose of releasing the contact between the trapezoidal contact block and the adjustment component can be achieved, and the two cleaning seats are separated, so that the space for the welding gun to work can be vacated, enabling the welding gun to approach the cable body and the terminal for welding.

[0037] A plurality of L-shaped contact rods 26 are fixed on the servo motor 25 and are circumferentially and equidistantly distributed. A fourth guide rod 27 is fixed on the welding table 1. An L-shaped contact frame 28 is slidably connected to the fourth guide rod 27. A ninth spring 30 is connected between the L-shaped contact frame 28 and the welding table 1.

A moving block 37 is slidably connected to the support rods 41. The moving block 37 is fixedly connected to the lower end of the first jaw 2. A first electric push rod 29 is fixed on one side of the L-shaped mounting seat 40, and the piston rod of the first electric push rod 29 is fixedly connected to the moving block 37.

[0039] When the device is in use, refer to Figures 1 - 9, place the cable body 19 on the two clamping seats 3. By adjusting the distance between the clamping ends of the first clamping jaw 2, make the two clamping seats 3 approach each other, prompting the circumferential surface of the cable body 19 to contact the rotating roller 18. Then, clamp and fix the circumferential surface of the wiring terminal 20 through the second clamping jaw 42. The centers of the cable body 19 and the wiring terminal 20 are located on the same straight line. When the first electric push rod 29 pushes the moving block 37 to slide on the two support rods 41, it prompts the first clamping jaw 2 to move horizontally. At the same time, the piston rod of the first electric push rod 29 drives the mounting frame 9, the welding gun 34, and the trapezoidal abutting block 10 to move vertically downward, so as to realize the abutment between the trapezoidal abutting block 10 and the third abutting rod 101 on the adjusting component, prompting the third abutting rod 101 to move horizontally on the welding table 1 and abut against the seesaw 103 at one end, causing the seesaw 103 to deflect on the welding table 1, and the torsion spring 104 to store energy, prompting one end of the seesaw 103 to abut against the lower end of one of the cleaning seats 4, causing the cleaning seat 4 to slide on the first guiding rod 11, and the second spring 12 to store energy. At the same time, the push block 105 fixed on the third abutting rod 101 pushes the other cleaning seat 4 to slide on the first guiding rod 11, prompting the two cleaning seats 4 to fit together, and the two wire brush blocks 5 to contact the circumferential surface of the cable body 19;

[0040] When the servo motor 25 drives the second clamping jaw 42 to swing back and forth on the welding table 1, the L-shaped abutting rod 26 fixed on the servo motor 25 intermittently abuts against the L-shaped abutting frame 28, prompting the L-shaped abutting frame 28 to move horizontally back and forth on the fourth guiding rod 27. The ninth spring 30 continuously stores energy and releases elastic force, which can realize that the L-shaped abutting frame 28 drives the horizontal end of the second abutting wedge 31 to abut against the lower end of the second abutting rod 16, prompting the second abutting rod 16 to move upward and abut against the first abutting wedge 6. The fourth spring 17 continuously stores energy and releases elastic force, which can realize that the first abutting wedge 6 drives one of the wire brush blocks 5 to slide on the cleaning seat 4 and abut against the wire brush block 5 on the other cleaning seat 4. At the same time, the guiding column 14 slides on the arc-shaped groove 13, and the third spring 15 continuously stores energy and releases elastic force, and the two wire brush blocks 5 slide back and forth on the two cleaning seats 4; The servo motor 25 drives the L-shaped abutting rod 26 to twist left and right and intermittently abut against the L-shaped abutting frame 28, which can realize the purpose of automatically polishing and removing the oxide layer of the cable body 19 by the reciprocating sliding of the two wire brush blocks 5. At the same time, it also drives the wiring terminal 20 to swing. The cable body 19 and the wiring terminal 20 are inserted in a twisting manner, which can reduce the frictional resistance and make the insertion process smoother;

[0041] When the cable tie tied to the cable body 19 abuts against one side of the cleaning base 4 during movement, the guiding post 14 in a reciprocating sliding state abuts against the first abutting rod 8, and the first spring 81 stores energy, prompting the first abutting rod 8 to drive the cutter 7 to move to cut the cable tie. On the one hand, the obstruction is reduced, enabling the cable body 19 to be fully inserted into the terminal 20. On the other hand, the covered surface of the cable body 19 can be exposed for oxide layer polishing treatment to improve the conductive effect.

[0042] Embodiment 2 is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 9 , there is another technical solution for the adjusting component. The adjusting component includes a U-shaped abutting frame 106. A second guiding rod 107 is fixed on the welding table 1. The U-shaped abutting frame 106 is elastically connected to the second guiding rod 107 through a sixth spring 108, and the U-shaped abutting frame 106 abuts against the lower ends of the two cleaning bases 4. One side of the trapezoidal abutting block 10 abuts against a wedge-shaped abutting frame 109. The wedge-shaped abutting frame 109 is elastically connected to the welding table 1 through a seventh spring 110, and one end of the wedge-shaped abutting frame 109 abuts against the U-shaped abutting frame 106.

[0043] Refer to Figure 5 , when the trapezoidal abutting block 10 moves downward, it can abut against the wedge-shaped abutting frame 109, prompting the wedge-shaped abutting frame 109 to move horizontally on the welding table 1. The seventh spring 110 stores energy. The wedge-shaped abutting frame 109 moves horizontally and abuts against the U-shaped abutting frame 106, prompting the U-shaped abutting frame 106 to move vertically upward on the second guiding rod 107. The sixth spring 108 stores energy, and the purpose of enabling both sides of the U-shaped abutting frame 106 to abut against the two cleaning bases 4 simultaneously can be achieved, making the two cleaning bases 4 fit together.

[0044] Embodiment 3 is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 9 , a material receiving groove 21 is formed on the welding table 1. A third guiding rod 22 is arranged on one side of the material receiving groove 21. Two pushing plates 23 are slidably connected to the third guiding rod 22. An eighth spring 24 is connected between the pushing plate 23 and the welding table 1.

[0045] Part of the cut cable tie may fall onto the surface of the welding table 1, and the accumulation will affect the welding of the cable body 19. It is necessary to push the cable tie into the material receiving groove 21 for centralized processing. Refer to Figure 5 and Figure 6, when the L-shaped contact frame 28 reciprocates, it can drive the U-shaped contact block 32 to contact the lower ends of the two pushing plates 23, so as to achieve the purpose that the two pushing plates 23 slide closer to each other on the third guide rod 22, and the eighth spring 24 stores energy, which is convenient for the pushing plates 23 to automatically gather the cable ties that fall onto the surface of the welding table 1 and push them into the material receiving groove 21, which can reduce the situation of manual frequent shutdown for cleaning cable ties and significantly improve the continuity of welding operations.

[0046] Embodiment 4, this embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 9 , a second electric push rod 33 is fixed on one side of the welding table 1, and a hollow rod 35 is fixed at the end of the piston rod of the second electric push rod 33. The hollow rod 35 is slidably connected to one end of the mounting frame 9, and a tenth spring 36 is connected between the hollow rod 35 and the mounting frame 9.

[0047] A corrugated plate 38 is fixed on one side of the mounting frame 9, and a contact strip 39 is fixed on one side of the L-shaped contact rod 26. The contact strip 39 is located on one side of the corrugated plate 38.

[0048] Reference Figures 2 - 7 , when the cable body 19 and the terminal 20 are completely inserted, when the second electric push rod 33 drives the mounting frame 9 to continue to move downward, at this time, the trapezoidal contact block 10 is separated from the adjusting component, prompting the two cleaning seats 4 to separate, so that the welding gun 34 can approach the cable body 19 and the terminal 20 for welding. At the same time, the servo motor 25 drives the terminal 20 and the cable body 19 to rotate in one direction. The cable body 19 rotates on the rotating roller 18. When the welding gun 34 keeps the angle unchanged, the welding wire can be melted and evenly distributed on the terminal 20 and the cable body 19, reducing the welding dead angle, improving the welding efficiency and quality. At the same time, the L-shaped contact frame 28 can drive the contact strip 39 to move. When the trapezoidal contact block 10 moves downward, it drives the corrugated plate 38 to move synchronously, so that the corrugated plate 38 is in the moving track of the contact strip 39. During the movement of the contact strip 39, it intermittently contacts the corrugated plate 38, prompting the mounting frame 9 to slide reciprocally in a small amplitude on the hollow rod 35, and the tenth spring 36 continuously stores and releases elastic force, so that the welding gun 34 can reciprocate during the welding process, which can increase the weld area between the terminal 20 and the cable body 19 and further improve the welding quality;

[0049] When the welding is completed, the mounting frame 9 moves upward, which can achieve the re-contact of the trapezoidal contact block 10 and the adjusting component, so that the two cleaning seats 4 can fit together again, and the welding slag on the weld can be cleaned by the wire brush block 5.
