[0003] The basic principle of the operation of a stamping die is to use the power of a press machine to apply pressure to metal or non-metal sheet materials through a stamping die installed on the press machine, so that the metal or non-metal sheet materials are separated or plastically deformed, thereby obtaining the required workpiece. The stamping die usually includes an upper die and a lower die, the upper die is fixed on the slide of the press machine, and the lower die is fixed on the workbench of the press machine. During operation, the metal or non-metal sheet materials are sent to the lower die, and the upper die is lowered to stamp the metal or non-metal sheet materials to form the required shape; when the upper die is raised, the workpiece after stamping is ejected by the ejection mechanism, and the waste material is removed by the unloading mechanism.

[0004] In the prior art, the cutting knife in the stamping die is generally in a vertical direction, and the cutting knife cuts the workpiece downward along the vertical direction to obtain the required shape.
