The quality and performance of products are inseparable from the production process. In order to ensure the quality of products, it is necessary to control the production process. Take the stamping and stretching die for example. In the production process, the production process generally has the following characteristics:
1. The drawing die can process parts with large size and complex shape, such as stopwatch of watch and clock, longitudinal beam of automobile, covering parts, etc. in addition, the cold deformation hardening effect of materials during stamping makes the stamping strength and rigidity higher.
As like as two peas, 2, stamping die ensures the size and shape accuracy of stamping parts, and generally does not destroy the surface quality of stamping parts, and the life of dies is generally longer. So stamping quality is stable, interchangeability is good, and has the characteristics of “exactly the same”.
3. Generally, there is no chip and broken material in stamping, the consumption of material is less, and other heating equipment is not needed. Therefore, stamping is a kind of material saving and energy-saving processing method, and the cost of stamping parts is low.
4. It is easy to realize mechanization and automation because stamping is based on stamping die and stamping equipment. The stroke times of ordinary press can reach dozens of times per minute, and high-speed pressure can reach hundreds or even more than 1000 times per minute, and each stamping stroke may get one punch.
