[0002] Stamping is a pressure processing method that uses a stamping die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the desired parts. Stamping dies are particularly widely used in the processing of automotive parts.

[0003] At present, when stamping automobile parts, workers are required to place the parts under the stamping equipment, and then start the stamping equipment for stamping. After stamping, the formed parts need to be taken out from the mold. There are still some problems in this process. First, the parts need to be held manually and placed under the stamping equipment, so there are certain safety hazards. In addition, the parts need to be taken out after stamping. Since the workpiece is close to the inside of the mold after stamping, it takes more time to cut the material, resulting in low stamping efficiency.
