4 precautions for the production of precision stamping parts 'hardware'

Please listen to the four major considerations in the production of precision stamping parts. 1. Reasonable mold design for precision stamping parts: 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. In the daily mold production of precision stamping parts, care should be taken to maintain 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 stamping parts to turn over and twist becomes greater. 3. Adding a strong pressure function to the precision stamping parts: 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 punching time The stamping parts are turned over, twisted and deformed. 4. Beveled or curved at the edge of the punch of precision stamping parts: This is an effective way to reduce the cutting force. 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.
