- 1. In the daily mold production of metal stamping parts processing, attention should be paid to maintaining the sharpness of the 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 the stamping part to turn over and twist becomes greater.
- 2. Add a strong pressure function: that is to increase the size of the press part of the discharge insert (normal discharge insert thickness H+0.03mm) to increase the pressure on the material on the side of the die, thereby suppressing the production of stamping parts during punching Turning materials, twisting and deforming.
- 3. The edge of the punch edge of the metal stamping parts is trimmed with a bevel or arc: this is an effective method to reduce the cutting force. By reducing the buffer cutting force, the tensile force on the material on the side of the die can be reduced, so as to achieve the effect of suppressing the turning and twisting of the stamping parts.
- 4. Reasonable die 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 punching is arranged first, and then a smaller area of punching is arranged to reduce the impact of the punching force on the forming of the stamping part.
