[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, which is called 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 separate or plastically deform the material, thereby obtaining the desired parts. Patent No. CN202322238204.6 discloses a metal stamping die, which relates to the field of stamping die technology, including: a fixing portion; a collecting portion arranged inside the fixing portion; and a tightening portion arranged below the collecting portion.
