[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a 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.

[0003] In the process of using stamping dies, waste cleaning has always been an important issue affecting production efficiency and product quality. The waste generated by existing stamping dies during the stamping process often needs to be cleaned manually or mechanically, which not only increases the difficulty of operation, but also wastes manpower and reduces production efficiency. Therefore, it is of great significance to develop a stamping die that can automatically clean waste. Utility Model Content

[0025] In this embodiment, the chassis 16 is used to protect the stepper motor 17 to prevent the stepper motor 17 from being exposed to the outside and being worn. The die handle at the top of the upper die seat 3 is used to connect the punch 6 to the punch press. When in use, the workpiece is placed on the unloading plate 25, and then pressure is applied by the punch press to push the punch 6 downward to perform stamping processing on the workpiece. The waste generated during stamping falls into the collecting drawer 15 through the lower die seat 1, and then the stepper motor 17 is started to drive the screw rod 19 to rotate, driving the push plate 22 to move forward, and the waste in the collecting drawer 15 can be pushed out of the collecting drawer 15 through the guide plate 24, and the waste is automatically cleaned, with low operation difficulty and high production efficiency.
