Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. Today's high-strength steel and ultra-high-strength steel have realized the lightweight of vehicles and improved the collision strength and safety performance of vehicles, so they have become an important development direction of automotive steel. However, with the improvement of the strength of the sheet metal, the traditional cold stamping process is prone to cracking during the forming process, which cannot meet the processing requirements of high-strength steel plates. In the case that the forming conditions cannot be met, the hot stamping forming technology of ultra-high-strength steel plates is gradually being studied internationally. This technology is a new process that integrates forming, heat transfer and structural phase transformation. It mainly uses the characteristics of increased plasticity and reduced yield strength of sheet metal in the high-temperature austenite state, and is formed through a mold.
The materials for making stamping dies include steel, hard alloy, steel-bonded hard alloy, zinc-based alloy, low melting point alloy, aluminum bronze, polymer material and so on. Most of the materials for manufacturing stamping dies are mainly steel. The types of commonly used die working parts materials are: carbon tool steel, low alloy tool steel, high carbon high chromium or medium chromium tool steel, medium carbon alloy steel, high speed steel , matrix steel and hard alloy, steel bonded hard alloy and so on.
