Precision stamping processing is an industrial industry that manufactures and shapes metal materials.
The materials for the stamping die are steel, hard alloy, steel-bonded hard alloy, zinc-based alloy, low-melting alloy, aluminum bronze, polymer material, and the like. At present, most of the materials used in the manufacture of stamping dies are mainly steel. The types of commonly used mold working parts are: carbon tool steel, low alloy tool steel, high carbon high chromium or medium chrome tool steel, medium carbon alloy steel, high speed. Steel, base steel and hard alloy, steel bonded carbide and so on.
The carbon tool steel used in the mold is T8A, T10A, etc. The advantages are good processing performance and low price. However, the hardenability and the red hardness are poor, the heat treatment deformation is large, and the bearing capacity is low.
The material used in the stamping die belongs to the cold-working die steel, which is a die steel with a large application volume, a wide use surface and the most variety. The main performance requirements are strength, toughness and wear resistance. At present, the development trend of cold work die steel is based on the performance of high alloy steel D2 (corresponding to China's Cr12MoV). It is divided into two branches: one is to reduce the carbon content and the amount of alloying elements, and to improve the uniformity of carbide distribution in steel. , to highlight the toughness of the mold. For example, 8CrMo2V2Si of American Vanadium Alloy Steel Company and DC53 (Cr8Mo2SiV) of Japan Datong Special Steel Company. The other is a powder high-speed steel developed for high-speed, automated, and mass-produced production with the main purpose of improving wear resistance.
