Background

With the continuous progress of science and technology and the rapid development of stamping production, higher and higher requirements are put on stamping design work. The stamping design is a very technical work, and the quality of the stamping design not only directly affects the quality, cost and production efficiency of stamping products, but also affects the organization and management of stamping production. Therefore, the stamping design work not only requires that the designer have a better theoretical basis, abundant design experience, skilled design skills and carefully responsible working attitude, but also requires that the designer can acquire latest scientific and technical knowledge in time on the basis of continuously accumulating the design experience and master modern design and calculation means as soon as possible. Only then can the stamping design work be adapted to the rapidly evolving needs of industrial production. Stamping is also an important aspect in the processing industry of the national economy as an industry. According to statistics, the stamping parts account for a considerable proportion in various industries, and especially account for a larger proportion in the aspects of automobiles, motors, instruments, military industry, household appliances and the like. The application range of stamping is very wide, and the stamping is needed from fine electronic elements, instrument pointers to covering parts and girders of heavy-duty automobiles, end sockets of high-pressure containers, skins of aerospace vehicles, fuselages and the like. The stamping design is not only the basis of the preparation work of stamping production, but also the basis for organizing formal production.

Production practices prove that the reasonable process scheme and the die structure not only provide technical guarantee for stabilizing the product quality and reducing the stamping cost, but also create favorable conditions for production organization management. On the contrary, any error or mistake of the stamping design can bring undesirable loss to the production, even cause serious accidents of human bodies and equipment. Stamping design is a rigorous, delicate and complex technical task that must be subjected to production checks. It is only possible to speak of successful press production if a successful press design is first ensured. Therefore, the press design plays an important role in press production as a technical preparation for press production.
