[0018] The working principle of the present application is as follows: In the actual use process of the new energy motor special-shaped coil forming device, first, the copper wire 8 to be processed is sent into the device through the previous process, guided through the copper wire guiding mechanism 7 from the entrance end, and sequentially passes through the cutting mechanism 9, the mold closing mechanism 5 and the shearing fixing mechanism 6. When the photoelectric sensor 635 in the shearing fixing mechanism 6 detects the copper wire 8 inserted into the fixing unit 63, the detection signal is transmitted to the fixing cylinder 633 and the cutting mechanism 9 in turn. First, the fixing cylinder 633 drives the fixing block 634 to extend forward to press and fix the copper wire 8 to be processed on the fixing base 632, and then the cutting mechanism 9 starts to cut the copper wire 8 to be processed, so as to obtain the copper wire with the length of the special-shaped coil product 80.

When the lower V-shaped section 81 is punched and formed, the left lower forming air cylinder 35 and the right lower forming air cylinder 34 drive the left lower forming block 38 and the right lower forming block 37 to move upward, respectively. The cooperation of the outer mold side slope 513, the inner mold side slope 524 and the lower side forming slope 381 provides a guiding effect for the upward and downward movement of the left lower forming block 38 and the right lower forming block 37, improves the stability of the punching and forming, and finally punches the right outer vertical line section 82 and the left inner vertical line section 83 at both ends of the lower V-shaped section 81 through the two symmetrical lower side forming cutter heads 382; When the lower V-shaped section 81, the right outer vertical line section 82 and the left inner vertical line section 83 at the bottom and both sides of the copper wire 8 to be processed are punched and formed, the left inner vertical line section 83 is adjusted inward by the adjusting block 56 driven by the coil adjusting air cylinder 55, so that the left inner vertical line section 83 moves inward and the right outer vertical line section 82 moves outward.
