Hardware stamping refers to the mold for steel / non-ferrous metal and other sheet materials, which is formed into a specified shape by a press at room temperature. Compared with other methods of mechanical processing and plastic processing, stamping parts processing has many unique advantages in both technical and economic aspects. The main performance is as follows.
(1) The production efficiency of metal stamping is high, the operation is convenient, and it is easy to realize mechanization and automation. This is because metal stamping relies on dies and stamping equipment to complete processing. The stroke times 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. It is possible to get a punch.
(2) As the metal stamping guarantees the size and shape accuracy of the metal stamping parts during metal stamping, and generally does not damage the surface quality of the stamping parts, and the life of the mold is generally long, the quality of metal stamping is stable, the interchangeability is good, "Identical" characteristics.
(3) Metal stamping can process parts with a large size range and more complex shapes, such as small stopwatches for watches and clocks, car beams, cover parts, etc., plus the cold deformation hardening effect of materials during metal stamping, and metal stamping. The strength and stiffness are both high.
(4) Metal stamping generally does not generate chips and scraps, consumes less material, and does not require other heating equipment. Therefore, it is a material-saving and energy-saving processing method, and the cost of metal stamping parts is low.
