[0002] Stamping dies are special process equipment used to process corresponding metal materials into parts or semi-finished products during cold stamping. The required parts are obtained by stamping at room temperature using a die installed on a press to apply pressure to the metal material to cause separation or plastic deformation. These parts are widely used in multiple accessory fields.

[0003] Existing metal stamping parts are directly formed by a die and a push-down stamping. When the metal material is placed inside the die, it is difficult to limit the position of the metal material. The vibration generated by the up and down movement of the model can easily cause the metal material to move, causing the stamping position to gradually shift, thereby reducing the stamping quality. In addition, due to the large downward thrust applied to the metal during stamping, the connection between the hydraulic equipment and the mold is deformed due to the impact between the molds, causing the interface to deform and fall off, shortening the service life of the metal forming mold.
