[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. At room temperature, a die installed on a press is used to apply pressure to the material to separate or plastically deform it, thereby obtaining the desired parts. The stamping die consists of a fixed part and a movable part. The fixed part is fastened to the workbench of the press with a pressing plate, bolts, etc. The movable part is generally fastened to the slide of the press and is widely used in various fields, including automobiles, electronics, and daily hardware. Stamping dies use various types of stamping die heads depending on the processed products and the materials used for the products. Flexible changes in the stamping die heads according to different production goals to adapt to a variety of working conditions can greatly broaden the scope of use of stamping dies.
