Punches also have upper molds, outer molds, punches, etc. Punches are divided into a-type punches, t-type punches, and special-shaped punches. The punch is a metal part installed on the stamping die and used for direct contact with the material to deform and cut the material.
Die punches generally use high-speed steel and tungsten steel as materials, such as high-speed steel punches and tungsten steel punches, and high-speed steel is the most commonly used material. Commonly used are CR12, CR12MOV, asp23, skd11, skd51, skd61, etc. Tungsten steel materials are generally used for punching and shearing dies, which require higher requirements.
