How many aspects does the value of the metal stamping part depend on?

The size of the edge value of metal stamping parts mainly depends on the following aspects: 1. The mechanical properties of the material of metal stamping parts. The edge value of hard materials can be smaller, and the edge value of soft materials and brittle materials should be larger; 2. The thickness of the metal stamping parts, the thicker the material, the greater the edge value; 3. The shape of the blanking part And size. The more complex the shape of the part, the smaller the fillet radius, and the larger the edge value; 4. Feeding and blocking methods; when feeding by hand, the edge value with the side pressure device can be smaller; use the side edge to fix the distance The value of the overlap is smaller than that of the fixed distance with the stopper pin; 5. Discharging method; the value of the elastic discharge is smaller than the value of the rigid discharge; recommended article: in the processing of stamping parts ，What are the conditions to increase or decrease the blanking gap value?Previous article: How to calculate the gap between the convex and concave dies in the production of stamping parts?
