Comparison of stamping processing and traditional processing technology

The die used for stamping is called stamping die, or die for short. The die is a special tool for batch processing of materials (metal or non-metal) into the required punches. Punching dies are very important in stamping. Without a die that meets the requirements, mass stamping production will be difficult; without advanced stamping dies, advanced stamping processes cannot be realized. The stamping process and die, stamping equipment and stamping materials constitute the three elements of stamping processing. Only when they are combined can stamping parts be obtained.　　 Compared with other methods of mechanical processing and plastic processing, stamping processing has many unique advantages in both technical and economic aspects. The main performance is as follows: 　　⑴The 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 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. May get a stamped part. ⑵The quality of stamping is stable, because the mold guarantees the size and shape accuracy of the stamping parts, and generally does not damage the surface quality of the stamping parts, and the life of the mold is generally long, so the quality of the stamping is stable, and the interchangeability is good. 'Exactly the same' feature. ⑶ Stamping can process parts with a larger size range. Stamping can 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, covering parts, etc., plus the cold deformation and hardening of the materials during stamping Effect, the strength and rigidity of stamping are higher.　　⑷ Less material consumption 　　 Stamping generally has no chips and scraps, less material consumption, and no other heating equipment, so it is a material-saving and energy-saving processing method, and the cost of stamping parts is lower.　　 However, the molds used in stamping processing are generally specialized. Sometimes a complex part requires five sets of molds to be processed and formed, and the mold manufacturing has high precision and high technical requirements. It is a technology-intensive product. Therefore, only when the stamping parts are produced in large batches, the advantages of stamping can be fully realized, so as to obtain better economic benefits.　　 Stamping processing is widely used in modern industrial production, especially in mass production. Quite a lot of industrial sectors are increasingly using stamping methods to process product parts, such as automobiles, agricultural machinery, instruments, meters, electronics, aviation, aerospace, home appliances, and light industry.
