Abstract: Automobile stamping die is an important process of automobile production equipment, its design and manufacturing time accounts for about 2/3 of the automobile development cycle, is one of the main constraints of automobile replacement.

Automobile stamping die is an important process equipment of automobile production, its design and manufacturing time accounts for about 2/3 of the automobile development cycle, is one of the main constraints of automobile replacement. Automobile stamping die has the characteristics of large size, complex working surface and high technical standard, which belongs to technology-intensive products. In the past, single process die and compound die are widely used in automobile stamping die structure design. With the improvement of technology and equipment level, multi-station die and progressive die, which can reduce cost and improve production efficiency, are gradually applied in the design and manufacture of automobile stamping die, and become the development direction of automobile stamping die manufacturing technology.

Stamping die is a processing tool that processes raw materials and endows them with complete configuration and precise size. It is mainly used for efficient and mass production of relevant parts in industrial products. With the development of modern industry, the application of mold is more and more widely, in automobiles, electronics, instruments and meters, home appliances, aerospace, building materials, motors and communication equipment and other products, about 60-80% of the parts and components have to rely on mold processing molding, so it is known as the "mother of industry".

The development of automobile stamping die industry is closely related to the development of downstream automobile industry. The steady and rapid development of downstream automobile industry will greatly promote the development of automobile stamping die industry. The steady and rapid development of the automobile industry has created a good environment for the development of the automobile stamping die industry. In the production process of the automobile, more than 90% of the parts need to rely on the mold forming, and the manufacture of an ordinary car needs about 1,000 to 1,500 sets of stamping die. The steady and rapid development of downstream automobile industry has created a good environment for the development of automobile stamping die industry.
