The stamping die usually comprises an upper die and a lower die. The upper die is provided with a punch, and the lower die is provided with a lower die forming block matched with the punch. The workpiece is processed and formed by stamping the lower die forming block with the punch.

[0003] For high-voltage wiring harness, terminal and shield ring pressing is one of the important processes. Patent CN 208067126 U discloses an automobile wiring harness terminal pressing auxiliary support seat, which adopts the mode of setting a baffle at the end of the telescopic rod of the telescopic mechanism to position the relative position of the wiring harness on the pressing lower die, and then realizes the positioning and pressing of the wiring harness and the terminal.
