Processing characteristics of metal stamping parts

The dies used in metal stamping parts are called stamping dies, or die for short. The die is a special tool for batch processing of materials (metal or non-metal) into the required stamping parts. Punching dies are very important in stamping. If there is no die that meets the requirements, it is difficult to stamp out in batches; without improving the technology of punching dies, it is impossible to improve the stamping process. The stamping process, die, stamping equipment and stamping materials constitute the three elements of stamping processing. Only when they are combined, can stamping parts be produced.

Compared with other processing forms such as mechanical processing and plastic processing, metal stamping processing has many advantages in terms of technology and economy. The main manifestations are as follows:

(1) Stamping generally does not produce chips and scraps, consumes less material, and does not require other heating equipment, so it is a material-saving and energy-saving processing method, and the cost of producing stamping parts is lower.

(2) Since the mold guarantees the size and shape accuracy of the stamping parts during the stamping process, and generally does not destroy the surface quality of the stamping parts, and the life of the mold is generally longer, the quality of the stamping is not bad, and the quality of the stamping is not bad. Well, it has the characteristics of "exactly the same".

(3) Metal stamping parts process parts with a larger size range and more complex shapes, such as stopwatches as small as clocks and clocks, as large as automobile longitudinal beams, cage covers, etc., plus the cold deformation and hardening effect of the material during stamping. Both strength and rigidity are high.

(4) The production efficiency of metal stamping parts processing is high, and the operation is convenient, and it is easy to realize mechanization and automation. Because stamping relies on punching 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, and each stamping stroke can get a punch Therefore, the production of metal stamping parts can achieve efficient mass production.
