What is the impact of design on the service life of stamping dies?

Design is the key step in mold production, the initial link of production, and controls the entire process of mold production. Therefore, design also has a great impact on the service life of the mold. The design mainly affects the service life of the stamping die from the following two aspects .

(1) The precision of the guide mechanism of the mold. Accurate and reliable guidance has a great impact on reducing the wear of the working parts of the mold and avoiding the gnawing of the convex and concave dies, especially the blanking die, compound die and multi-station progressive die without gap and small gap are more effective. In order to improve the life of the mold, it is necessary to correctly select the guiding form and determine the accuracy of the guiding mechanism according to the requirements of the nature of the process and the accuracy of the parts.

(2) The geometric parameters of the cutting edge of the die (convex and concave die). The shape, fit clearance and fillet radius of the convex and concave dies not only have a great influence on the forming of stamping parts, but also have a great influence on the wear and life of the die. For example, the matching clearance of the mold directly affects the quality of the blanking parts and the life of the mold. For higher precision requirements, a smaller gap value should be selected in the design; otherwise, the gap can be appropriately increased to improve the life of the mold.
