The processing of stamping and stretching parts is powered by conventional or one-to-one stamping equipment

The processing of stamping and stretching parts is a production technology of product parts with the help of the power of conventional or stamping equipment to make the sheet directly subjected to the deformation force and deform in the die, so as to obtain the shape, size and performance. Sheet metal, die and equipment are the three elements of stamping processing. Stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet metal stamping, referred to as stamping. Compared with castings and forgings, metal stamping parts are thin, uniform, light and strong. Metal stamping parts can produce workpieces with stiffeners, ribs, undulations or flanging that are difficult to manufacture by other methods, so as to improve their rigidity

many colleagues engaged in the processing of stamping and stretching parts generally have such a taste. Why are there wrinkles and cracks in the processing of stamping and stretching parts? Here is a small series to teach you a problem about the processing technology of pull-down and extension parts

1. There are many reasons for poor drawing parts. The general quality of coil, sheet and die will affect the quality of final drawing parts.

2. If the die is roughly cleaned and assembled, there will be sharp damage, and the convex concave problem will increase significantly. Therefore, details should be fully considered at every juncture of the whole manufacturing process, even if quality problems are prohibited, which will affect the final product profile

3. The manipulation in the drawing process and the clamping, taking and unloading of station instruments also have a general damage to the quality of the parts
