A good way to improve the mold of precision stamping parts 'hardware'

A good way to improve precision stamping die: 1. Improve the design of precision stamping die. Whether the design of the stamping die is reasonable is the basis for improving the durability of the stamping die. Therefore, when designing the stamping die, effective measures should be taken to improve the durability of the stamping die. For example, the life of the small hole punching die is often reflected in the punching die for punching small holes. For this type of stamping die, the length of the small punch should be shortened as much as possible in the design to increase the strength. At the same time, the method of guiding sleeves should be used to strengthen the small punch for protection. In addition, in the design of the stamping die, factors such as the form of the die base, the fixing method and guiding form of the convex and concave die, the determination of the pressure center, and the rigidity of the upper and lower templates should be fully considered. Especially for the blanking die, the selection of the gap value has a great influence on the durability. When designing, the gap of the stamping die should be selected reasonably, and the gap value should not be too small, otherwise it will affect the service life and durability of the stamping die. Practice has proved that, without affecting the quality of the stamping parts, properly enlarging the gap can greatly improve the durability of the stamping die, sometimes several times or tens of times. 2. Correct choice of die materials for precision stamping parts. Different stamping die materials have different strength, toughness and wear resistance. The use of materials under certain conditions can increase durability several times. Therefore, it is necessary to select good materials in order to improve the durability of the stamping die. The Toolox series of materials are a new type of pre-hardened tool steel with high toughness, high wear resistance, and basically no internal stress. And it has very high purity, very small grain size, and very high S and P content. Due to the special composition design, Toolox series materials have very excellent surface treatment properties. Among them, the surface hardness of Toolox44 can reach HRC65 or more after nitriding, and the surface hardness of Toolox40 can reach HRC62 or more. The surface hardness of Toolox33 can reach above HRC58, and the depth is as high as 1.8mm. 3. Reasonably carry out forging and heat treatment of precision stamping die parts
