What are the common methods for suppressing turning and distortion of stamping parts in metal stamping parts?
The following Xiaoshuo will take you to take a look at some common methods of suppressing turning and distortion of stamping parts when stamping metal stamping parts: 1. 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. 2. 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). 3. Add 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. 4. The end of the punch edge is trimmed with a bevel or arc. This is an effective way to reduce cushioning power. By reducing the cushioning cutting force, the tensile force on the side material of the die can be reduced, thereby achieving the effect of suppressing the turning and distortion of the stamping parts. 5. In daily mold production, care should be taken to maintain the sharpness of punching convex and concave die cutting edges. When the punching edge is worn, the tensile stress on the material will increase, and the tendency of stamping parts to turn over and twist becomes greater. The above are some common and practical methods to suppress turning and distortion of stamping parts when stamping metal stamping parts.
