The hydraulic cylinder 31 is started, and power is provided by the hydraulic cylinder 31. The output rod of the hydraulic cylinder 31 drives the upper die base 41 to press down, which in turn drives the stamping block 411 to press down, thereby stamping the wire harness terminals located on the forming groove 422. During this process, the servo motor 52 is started and provides power, driving the transmission shaft 55 to rotate, which drives the flower-shaped cam 56 to rotate synchronously. The cam on the flower-shaped cam 56 pushes out the top block 54, thereby pushing the sliding plate 53 to push close to the wire harness terminal to perform lateral positioning of the wire harness terminal, ensuring the stability of the wire harness terminal during the stamping process and reducing the wobbling of the wire harness terminal. After one stamping is completed, the return spring 59 returns, pushing the sliding plate 53 back to prepare for the next stamping.
