Metal stampings refer to steel/nonferrous metal and other sheet metal dies, which are formed to the specified shape with the pressure required for processing provided by the press at room temperature. Compared with other methods of mechanical processing and plastic processing, stamping has many unique advantages in both technical and economic aspects. The main performances are as follows.
(1) The production efficiency of metal stamping is high, and the operation is convenient, and it is easy to realize mechanization and automation. This is because metal stamping depends on stamping dies and stamping equipment to complete the processing. The number of strokes of ordinary presses can reach dozens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute. In addition, each stamping stroke may result in a stamping part.
(2) During metal stamping, because the die ensures the size and shape accuracy of the metal stamping parts, and generally does not damage the surface quality of the stamping parts, and the life of the die is generally long, the quality of metal stamping is stable, the interchangeability is good, and it has the characteristics of "identical".
(3) Hardware stamping can process parts with large size range and complex shape, such as stopwatch of clocks and watches, longitudinal beam of automobiles, covering parts, etc. In addition to the cold deformation hardening effect of materials during metal stamping, the strength and stiffness of metal stamping are high.
(4) Hardware stamping generally does not generate chips and scraps, with less material consumption and no need for other heating equipment, so it is a material saving and energy-saving processing method, and the cost of hardware stamping parts is low.
