What are the methods for stamping processing plants to suppress turning and distortion of stamping parts?

In the stamping process of the stamping processing plant, sometimes there will be turning and distortion, so how to avoid this from happening? Here the author will give you a detailed explanation. The first point: reasonable mold design. In the progressive die, the arrangement of the blanking sequence may affect the forming accuracy of the stamping parts. For the blanking of small parts of stamping parts, generally a larger area of u200bu200bpunching is arranged first, and then a smaller area of u200bu200bpunching is arranged to reduce the impact of the punching force on the forming of the stamping part. The second point: hold down the material. Overcome the traditional mold design and structure, open a material-containing gap on the discharge plate (that is, when the mold is closed, the discharge plate is attached to the concave mold, and the gap between the discharge plate and the concave mold where the material is contained is the material thickness t-0.03 ~0.05mm). In this way, the unloading plate moves smoothly during stamping, and the material can be compressed. The key forming part, the unloading plate must be made into a block-type structure to facilitate the solution of the wear (compression) loss of the pressing part of the unloading plate caused by long-term stamping, and the material cannot be compressed. The third point: add a strong pressure function. That is to increase the size of the press part of the unloading insert (normal unloading insert thickness H+0.03mm) to increase the pressure on the material on the side of the die, so as to prevent the stamping part from turning over and twisting during punching.
