Compared with other machining and plastic processing methods, stamping has many unique advantages both in technical and economic aspects. The main performance is as follows.
(1) The production efficiency of stamping processing is high, and the operation is convenient, and it is easy to realize mechanization and automation. This is because stamping is to rely on stamping die and stamping equipment to complete the processing, the number of stroke of ordinary press 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 punching piece.
(2) stamping due to the mold to ensure the size and shape precision of stamping parts, and generally does not destroy the surface quality of stamping parts, and the life of the mold is generally long, so the quality of stamping is stable, good interchangeability, with the characteristics of "exactly the same".
(3) stamping can be processed into a larger size range, the shape of the more complex parts, such as as small to the second hand of clocks and watches, as large as the car rail, covering parts, etc., plus the cold deformation hardening effect of stamping materials, stamping strength and stiffness are higher.
(4) stamping generally does not generate scraps, the consumption of materials is less, and does not need other heating equipment, so it is a kind of material saving, energy saving processing method, the cost of stamping parts is low.
