The characteristics and process requirements of multi-station precision progressive die

The characteristics of multi-station precision progressive die: 　　 multi-station precision progressive die has the characteristics of precision, high efficiency and long life. It is suitable for stamping small size, thin material, complex shape and mass production stamping parts. The number of stations of the multi-station precision progressive die can be as high as dozens, and the die can automatically feed and automatically detect the feeding error. Multi-station precision progressive die is often used for high-speed stamping. Therefore, productivity is greatly improved, the error of manual feeding is solved, the stamping equipment and workers are reduced, and the product accuracy is improved. Multi-station precision progressive die processing process requirements: 　　 Compared with ordinary molds, the structure of multi-station precision progressive die is more complicated, the manufacturing technology and manufacturing requirements are higher, and the cost of the mold is relatively high. The raw materials (coils) also have corresponding requirements, and higher requirements are put forward for the rationality of the mold design. Therefore, it is necessary to conduct a comprehensive analysis of the part before mold design, and then combine the structural characteristics of the mold and the forming process of the stamping part to determine the stamping process of the part. 　　 Multi-station precision progressive die requires high precision and long life. The main working parts of the die are often made of high-strength, high-alloy tool steel, high-speed steel or cemented carbide. The processing method often uses slow-moving wire electrode electrical processing and finished grinding.
