Metal stamping products are used in various industries, such as automobiles and household appliances. Automobile stamping parts are an important part of metal stamping industry.Stamping has many unique advantages in both technical and economic aspects. The main performance is as follows.
(1) The stamping process has the advantages of high production efficiency, convenient operation and easy realization of mechanization and automation. This is because stamping relies on stamping die and stamping equipment to complete the processing, ordinary press travel times can reach dozens of times per minute, high-speed pressure can reach hundreds or even thousands of times per minute, and each stamping stroke may get a stamping piece.
(2) Because the die ensures the dimension and shape accuracy of stamping parts, and generally does not destroy the surface quality of stamping parts, while the life of the die is generally longer, the stamping quality is stable, good interchangeability, and has the characteristics of "exactly the same".
(3) Stamping can produce parts with large size range and complex shape, such as the second hand of clock and watch, the longitudinal beam of automobile, covering parts and so on. With the cold deformation and hardening effect of materials during stamping, the strength and stiffness of stamping are higher.
(4) Stamping generally does not produce chips and debris, consumes less material, and does not require other heating equipment, so it is a material-saving, energy-saving processing method, and the cost of stamping parts is low.
Metal stamping can form sheet metal very efficiently. The metal stamping die is mounted on the press, and each stroke of the press forms a workpiece.The production of metal stamping is accomplished by metal stampers. Metal stamping dies are produced by machine tools or die factories. Some machine tools and die factories also produce stamping parts. Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can produce workpieces with stiffeners, ribs, undulations or flanges which are difficult to manufacture by other methods to improve their rigidity. Because of the use of precision die, the precision of workpiece can reach micron level, and the repetition accuracy is high, the specifications are consistent, and holes and convex tables can be punched out.
