The service life of the stamping die has seriously affected the cost and production efficiency of stamping products . Therefore, modern industrial production companies must adopt effective strategies to extend the service life of stamping dies in order to increase market competitiveness. Doing the following points well and prolonging the service life of the stamping die is not a problem. Reasonable design of stamping die structure To a certain extent, the service life of the stamping die depends on the rationality of the structural design of the stamping die. Therefore, modern industrial production companies must rationally design the structure of stamping dies in order to prolong the service life of stamping dies. In order to do this well, modern industrial production companies must first design the structure of the stamping die so that all parts are subjected to uniform forces as much as possible, and structures such as concave angles, sharp corners, and wall thicknesses are avoided as much as possible. In addition, the clearance of the stamping die must also be reasonably selected to ensure the quality of stamped products. In order to extend the service life of stamping dies, modern industrial manufacturers should also fully consider the following aspects: 1 When designing a punch, attention should be paid to guide protection and support. If the designed punch size is small, the structure of the mold should adopt its own protection and guide structure. 2 In the design of relatively weak parts (such as narrow groove and included angle, etc.), arc transition must be used to avoid stress concentration. It should be noted here that the arc radius should be 3 to 5 mm. 3 In the design of a relatively complex structure of the die, the inlay structure should be used to avoid stress concentration. 4 When designing a concave or convex die in a press forming die, the corner radius in its structure must be properly selected. 5 In order to effectively improve the stress state of the concave or convex die, it is possible to appropriately increase the clearance of the stamping die. This will help to reduce the degree and speed of wear of the concave or convex die edge, thus prolonging the service life of the stamping die. Correct use and maintenance of stamping dies In order to extend the service life of stamping dies, modern industrial manufacturers must pay attention to the use and maintenance of stamping dies, and adopt effective strategies to do both. In the specific work, the staff should do the following 3 points: 1 In order to reduce the degree of wear of the cushioning die, the depth of the punch into the die must be strictly controlled; 2 Once it is found that the roughness of the surface of the stamping mold is deteriorated, it is necessary to timely repair and polish the mold; 3 When storing stamping dies, be sure to reserve a certain gap between the upper and lower dies to avoid damage to the cutting edges. Improve the heat treatment process level of stamping dies The quality of the stamping die surface directly affects its service life, and its quality is directly affected by the heat treatment process level. Therefore, modern industrial production companies must constantly update and introduce advanced heat treatment processes to ensure the quality of the stamping die surface. In general, the heat treatment process of the stamping die mainly includes two parts, ie, strengthening and toughening of the matrix of the stamping die part and surface strengthening treatment of the stamping die. The purpose of strengthening and toughening the matrix of the stamping die parts is to enhance their strength and toughness, and to avoid deformation or breakage of the die as much as possible. At present, the heat treatment process mainly uses deformation heat treatment and low temperature quenching and tempering. It should be noted here that low-temperature quenching and tempering are suitable for ordinary cold work tool steels. The purpose of strengthening the surface of the stamping die is to improve its impact resistance, fatigue resistance and wear resistance. At this stage, the heat treatment Dingyi mainly includes three kinds, ie, surface treatment, chemical heat treatment and surface coating treatment. Among them, the common methods of surface treatment are EDM surface strengthening, shot peening and flame surface heating and quenching.
