Impact Of Mold Design On Life
|
|
Design is the key step and initial link in the mold, which controls the entire process of the mold. Therefore, design also has a great impact on the service life of the mold. The design mainly affects the service life of the stamping mold from the following two aspects.
(1) Precision of the guide mechanism of the mold. Accurate and reliable guidance has a great effect on reducing the wear of the mold's working parts and avoiding damage to the convex and concave molds, especially the gapless and small gap punching dies, composite dies and multi-stage progressive dies are more effective. In order to improve the life of the mold, the design of the guide and the accuracy of the guide mechanism should be correctly selected according to the requirements of the process nature and part accuracy.
(2) The geometric parameters of the cutting edge of the mold (convex, concave). The shape, fit clearance and fillet radius of the convex and concave dies not only greatly affect the forming of the stamping part, but also have a great influence on the wear and life of the die. For example, the fit clearance of the mold directly affects the quality of the blanking part and the life of the mold. For higher accuracy requirements, a smaller gap value should be selected in the design; otherwise, the gap can be appropriately increased to improve the mold life.
