[0043] It should be noted that the hydraulic cylinder 34 of the present invention pushes the copper rod into the forming cavity inside the cold heading box 26. The thrust of the hydraulic cylinder 34 ensures that the copper rod can be pressed in and shaped. The forming holes inside the cold heading box 26 are used to form the specific shape of the copper rod. The copper rod is squeezed in these holes to form the required shape.

[0044] A production process for copper bolts for new energy vehicles, comprising the following steps:

[0045] The rolled copper material is placed on the lifting plate 8. The lifting plate 8 is driven downward by the No. 1 motor 6 and the lead screw 9 so that it is at the same height as the roller 14 in the middle of the straightening mechanism 3. The free end of the copper material is inserted from one end of the frame 11 and then passed through the middle of the hollow disks 15 arranged in an alternating pattern. The copper material is straightened by the hollow disks 15. The electric lift and automatic straightening mechanism reduce manual operation, labor intensity and error rate. The copper material is automatically adjusted to the correct position of the straightening mechanism to ensure smooth transportation and prevent corners during transportation, thereby avoiding reduced processing accuracy and product quality.

[0046] After multiple straightening steps, the copper material passes through the hollow disk 15 and enters the processing box 16. The No. 1 cylinder 17 drives the cutting machine 18 to move up and down, thereby cutting the copper material into copper rods through the cutting machine 18. The copper rods enter the feed trough 20 in the guide plate 19 and are transported downward by the inclined feed trough 20. After straightening, the copper material is directly fed into the cutting and conveying system, which has a coherent process, reduces intermediate links, and improves production efficiency. The use of automated equipment for cutting ensures that the copper rods are of uniform size, providing homogenized raw materials for subsequent processing.

[0047] The No. 2 linear module 25 drives the pneumatic clamp 23 to move to the position corresponding to the No. 2 cylinder 21. The No. 2 cylinder 21 pushes the copper rod out from one side of the feed trough 20. The pneumatic clamp 23 clamps the copper rod and fixes it. Then, the No. 2 linear module 25 and the No. 1 linear module 24 place the copper rod in a position facing the hydraulic cylinder 34. The hydraulic cylinder 34 squeezes the copper rod into the cold heading box 26 and squeezes it in the forming cavity inside the cold heading box 26 to deform it. Then, the material return hydraulic cylinder 37 pushes the formed material to the top of the support bracket 33. The No. 5 cylinder 36 drives the support bracket 33 to move forward to the specified position. The No. 4 linear module 25 and the No. 1 linear module 24 Cylinder 29 drives the pneumatic three-jaw chuck 31 forward to clamp the deformed copper piece into the pneumatic three-jaw chuck 31. Cylinder No. 4 29 drives the copper piece to separate from the support bracket 33 through the pneumatic three-jaw chuck 31. The use of automated linear modules and pneumatic clamps quickly and accurately moves the copper rod to the processing position. The pneumatic clamps provide stable and reliable clamping, ensuring that the copper rod is fixed in position during the forming process and avoiding processing errors. Upsetting technology can complete metal deformation without heating, enhancing the strength and toughness of the material. Compared with hot forging, cold upsetting has faster production speeds and lower energy consumption, which helps reduce production costs.

[0048] The No. 3 linear module 27 drives the pneumatic three-jaw chuck 31 to move to the position corresponding to the thread rolling head 35. The No. 3 motor 30 drives the pneumatic three-jaw chuck 31 to cooperate with the copper part and the thread rolling head 35 to complete the thread forming. After forming, the pneumatic three-jaw chuck 31 opens, allowing the bolt to be discharged along the pouring chute. The clamping system not only stabilizes the copper part, but also cooperates with the support bracket to move to a precise position to prepare for the next operation; thread rolling technology can form high-precision threads without cutting off the material, maintaining the integrity of the material; automated precise control: through the precise control of the motor and module, the uniformity and accuracy of the thread forming are ensured; the automatically opened and closed chuck and pouring chute ensure the smooth discharge of the finished product, reduce manual cleaning, and improve production efficiency.

The production process of a new energy vehicle copper bolt production equipment according to claim 5, characterized in that: The following steps are involved: The rolled copper material is placed above the lifting plate (8), and the lifting plate (8) is driven downward by the No. 1 motor (6) and the lead screw (9) so that it is at the same height as the roller (14) in the middle of the straightening mechanism (3). The free end of the copper material is inserted from one end of the frame (11), and then passed through the middle of the hollow disks (15) arranged in an upper and lower staggered manner, and the copper material is straightened by the hollow disks (15); After the copper material has been straightened by multiple groups, it passes through the hollow disk (15) and enters the processing box (16). The No. 1 cylinder (17) drives the cutting machine (18) to rise and fall, thereby cutting the copper material into copper rods through the cutting machine (18). The copper rods enter the feed trough (20) in the guide plate (19) and are transported downward by the inclined feed trough (20); The second linear module (25) drives the pneumatic clamp (23) to move to the position corresponding to the second cylinder (21), the second cylinder (21) pushes the copper rod out from one side of the feed trough (20), the pneumatic clamp (23) clamps the copper rod, and then the copper rod is placed in a position facing the hydraulic cylinder (34) through the second linear module (25) and the first linear module (24); The hydraulic cylinder (34) squeezes the copper rod into the cold heading box (26), and squeezes it into the forming cavity inside the cold heading box (26) to deform it. Then, the material return hydraulic cylinder (37) ejects the formed material to the top of the support bracket (33). The No. 5 cylinder (36) drives the support bracket (33) to move forward to the specified position. The No. 4 cylinder (29) drives the pneumatic three-jaw chuck (31) forward to clamp the deformed copper piece into the pneumatic three-jaw chuck (31). The No. 4 cylinder (29) drives the copper piece to separate from the support bracket (33) through the pneumatic three-jaw chuck (31). The third linear module (27) drives the pneumatic three-jaw chuck (31) to move to the position corresponding to the thread rolling head (35), and the third motor (30) drives the pneumatic three-jaw chuck (31) to cooperate with the copper part and the thread rolling head (35) to complete the thread forming. After forming, the pneumatic three-jaw chuck (31) opens, allowing the bolt to be discharged along the pouring chute.
