What are the types of stamping parts processing technology

The processing techniques of stamping parts mainly include punching, bending and stretching. These techniques are widely used and involve all aspects of our daily lives. A good stamping process can achieve the purpose of saving materials, improving die life, product quality and production efficiency. Next, the precision author will introduce these three processes. 1. Stretching process; the rounded half-warp between the boss and the side wall of the stamping and stretched part, and the rounded corner R between the bottom end and the side wall should be as large as possible. The larger the rounded half-warp, the easier the stretched part will be drawn. Stretch forming, the stretched parts should be as symmetrical as possible or use top and bottom symmetrical stretched parts; it is convenient to stretch in pairs and then cut into two pieces; 2. Bending process; Avoid hole deformation during bending, There should be a moderate distance between the edge of the hole and the bend to prevent the deformation of the hole. Otherwise, the hole must be bent first and then punched; the length of the bent edge is not easy to be too small; the press-bent part should take into account the precise positioning and formation of the process hole as much as possible Double bending in pairs to change the bearing capacity; 3. Blanking process; The shape should be able to effectively nest the raw materials as much as possible, improve the material utilization rate, and the parallel lines or graphs should have moderate rounded corners to facilitate Mold production, maintenance and application; prevent too long slender appearance design; diameter and hole position should comply with the size of the drawing.
