Background

The stamping die is essential technological equipment for stamping production, is a technology-intensive product, and has direct relation with the design and manufacture of the stamping die, such as the quality, the production efficiency, the production cost and the like of the processed parts. Common nonferrous metals such as aluminum materials, brass, phosphor bronze and the like are accompanied by powder scraps in the progressive blanking process and are easy to adhere to the male die to form a thin dust belt, the blanking clearance is reduced due to the influence of the dust belt at the moment, meanwhile, the guide clearance between the male die and the stripper plate is also reduced, the discharging force is increased, more friction heat is easy to generate during the blanking of the nonferrous metals to cause the powder scraps to form a nodule, the discharging resistance is increased, the male die is blocked when a certain degree is reached, and the phenomenon that the powder scraps are blocked at the small male die frequently appears, even the small male die is broken.

Stamping dies are widely available and classified according to working properties, die structures and die materials, and are a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping, and are called cold stamping dies (commonly called cold stamping dies). Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part.

In the above-mentioned technical field, the commonly used technique is to apply a sheath or single-double reinforcement to the punch and then to give way to the stripper. The defects are that the processing is troublesome, the reinforcing effect is not good in the stamping process, the replacement is frequent, and the manufacturing cost is high.
