[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the cooperation of a sliding rack and a driven gear, enables the device to pull copper busbars by first passing the copper busbar through the inside of the die opening, and then moving the pulling jaws closer to the pulling die base via the first and second pulleys, so that the copper busbar is clamped into the inside of the jaw groove. At this time, the hydraulic cylinder drives the hydraulic rod to retract, causing the sliding rack to drive the driven gear to rotate, which in turn drives the connecting rod to rotate, and then the connecting rod drives the movable table to rotate towards the inside of the jaw groove, thereby clamping the copper busbar through the clamping tooth plate. Then, the first and second pulleys move the pulling jaws back to their original position to pull the copper busbar. This device can easily clamp and pull copper busbars of different thicknesses and widths, making the device convenient to use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 One embodiment of this utility model provides a copper busbar drawing device, including a straight track frame 1, with two fixing plates 2 between the inner sides of the two straight track frames 1. A drawing jaw 3 is fixedly installed on the top of one fixing plate 2, and a hydraulic cylinder 7 is fixedly installed on the top of the other fixing plate 2. A jaw groove 4 is provided on one side of the drawing jaw 3. Two movable platforms 19 are movably installed inside the drawing jaw 3. Clamping teeth 20 are bolted to the surface of each movable platform 19. A hydraulic rod 9 is fixedly connected to the output end of the hydraulic cylinder 7, and the hydraulic rod 9 is movably inserted into the interior of the drawing jaw 3.

[0021] The surface of the hydraulic cylinder 7 is provided with a flange 8, and the hydraulic rod 9 passes through the interior of the flange 8. A sliding rack 16 is fixedly installed at the end of the hydraulic rod 9. Both the upper and lower sides of the sliding rack 16 are meshed with driven gears 17, and the driven gears 17 are rotatably installed inside the pull jaws 3.

[0022] Connecting rods 18 are fixedly mounted on the surface of the driven gear 17, and the ends of the connecting rods 18 are fixedly connected to the movable table 19.

[0023] By utilizing the cooperation of the sliding rack 16 and the driven gear 17, when the device is drawing copper busbars, the copper busbar is first passed through the interior of the die opening 12. Then, the first pulley 5 and the second pulley 6 move the drawing jaws 3 to a position close to the drawing die base 10, and the copper busbar is clamped into the jaw groove 4. At this time, the hydraulic cylinder 7 drives the hydraulic rod 9 to retract, causing the sliding rack 16 to drive the driven gear 17 to rotate. This causes the driven gear 17 to drive the connecting rod 18 to rotate, which in turn causes the connecting rod 18 to drive the movable table 19 to rotate towards the inside of the jaw groove 4. Thus, the copper busbar is clamped by the clamping tooth plate 20. Then, the first pulley 5 and the second pulley 6 move the drawing jaws 3 back to their original position to draw the copper busbar. This device can easily clamp and draw copper busbars of different thicknesses and widths, making the device convenient to use.

[0024] A drawing die holder 10 is fixedly installed between two straight track frames 1. A diagonal brace 11 is fixedly installed on the surface of the drawing die holder 10, and a die opening 12 is fixedly installed inside the drawing die holder 10.

[0025] A pneumatic cylinder 13 is fixedly installed at the lower part of the mold opening 12. A pressure plate 14 is fixedly connected to the output end of the pneumatic cylinder 13. A fixed seat 15 is fixedly installed at the upper part of the mold opening 12.

[0026] By cooperating with the pneumatic cylinder 13 and the pressure plate 14, the device can be used to push the pressure plate 14 upward by the pneumatic cylinder 13, so that the copper busbar is pushed and clamped towards the fixed seat 15. This adjusts the height position of the copper busbar during the drawing process, so that the copper busbar can be kept in a straight position with the drawing jaws 3 during the drawing process, avoiding the copper busbar from breaking during the drawing process. At the same time, the copper busbar can be pre-straightened during the drawing process, which is convenient for subsequent straightening and other processing steps.

[0027] Two first pulleys 5 are provided on both sides of the fixed plate 2, and four second pulleys 6 are provided at the bottom of the fixed plate 2. The first pulleys 5 and the second pulleys 6 are in contact with the surface of the straight track frame 1.

[0028] When using this copper busbar drawing equipment, the copper busbar is first passed through the inside of the die opening 12. Then, the first pulley 5 and the second pulley 6 move the drawing jaws 3 to a position close to the drawing die base 10, and the copper busbar is inserted into the jaw groove 4. At this time, the hydraulic cylinder 7 drives the hydraulic rod 9 to retract, causing the sliding rack 16 to drive the driven gear 17 to rotate. This causes the driven gear 17 to drive the connecting rod 18 to rotate, which in turn causes the connecting rod 18 to drive the movable table 19 to rotate towards the inside of the jaw groove 4. The copper busbar is then clamped by the clamping tooth plate 20. Then, the first pulley 5 and the second pulley 6 move the drawing jaws 3 back to their original position to draw the copper busbar. This device can easily clamp and draw copper busbars of different thicknesses and widths, making the device convenient to use.

[0029] During the drawing process, the pressure plate 14 can be pushed up by the pneumatic cylinder 13, which will push the copper busbar towards the fixed seat 15 and clamp it, thereby adjusting the height position of the copper busbar during the drawing process. This ensures that the copper busbar is kept in a straight position with the drawing jaws 3 during the drawing process, preventing the copper busbar from breaking during the drawing process. At the same time, the copper busbar can be pre-straightened during the drawing process, which is convenient for subsequent straightening and other processing steps.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
