Real development of stamping technology
2023-02-17
The real development of stamping technology began with the industrial production of automobiles. At the beginning of the 20th century, the industrial production of Ford Motor in the United States greatly promoted the research and development of punching technology. The research work is basically carried out at the same time in sheet metal forming technology and formability. The key issues are fracture, wrinkling and springback, involving formability prediction, innovation of forming methods, and analysis and control of forming process. But for most of the 20th century, the mastery of stamping technology was basically experiential. The analysis tool is a classical theory of forming mechanics, which can solve very limited problems. Industrial developed countries attach great importance to the development of cold stamping production technology, such as the United States, Japan and other mold industry output value has exceeded the machine tool industry. The development trend of cold stamping can be seen from the steel composition of these countries. Stamping has become an important means and development direction of modern industrial production. With the accelerating pace of international integration and increasing market competition, people have increasingly realized the importance of product quality, cost and new product development capability.
