Main performance requirements of stamping die

The total amount of stamping die production in China is in the forefront in the world, and it has gradually changed from the big country to the die exporting country. Our existing mold production more than 30 thousand enterprises, employing about 1 million people, 2012 sales of 124 billion yuan, production and sales, production, quality and level has been further improved, especially the development of the automobile industry and the IT industry, boosting the mold grades improved, provide a guarantee for excellent mold manufacturing equipment to enhance the level of mold technology the.



Dalian stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping process, called cold stamping dies (commonly known as cold punching dies). Stamping is a pressure processing method that uses pressure on the press to produce pressure and separate plastic deformation at room temperature.



Stamping dies must withstand shock, vibration, friction, high pressure and tensile, bending and twisting loads. Even working at high temperatures (such as cold extrusion), the working conditions are complex, and are easy to wear, fatigue, fracture and deformation. Therefore, the requirements for the working parts of the mold are higher than that of the ordinary parts.



The material used for the stamping die is a cold working die steel. It is a mold steel with a large amount of application, wide use and most kinds. The main performance requirements are strength, toughness and wear resistance. The current development trend of cold working die steel in high alloy steel D2 (equivalent to our performance on the basis of Cr12MoV), divided into two branches: one is to reduce the amount of carbon and alloy elements, improve the distribution uniformity of carbides in steel, improve the toughness of the mold.
