Matters needing attention in metal stamping parts
The metal stamping manufacturers explain to you, the notes of the metal stamping parts: 1. Reasonable mold design: In the progressive die, the arrangement of the cutting sequence may affect the accuracy of the stamping part forming. For the blanking of small parts of stamping parts, generally arrange a larger area of blanking and blanking, and then arrange a smaller area of blanking and blanking to reduce the impact of punching force on the forming of stamping parts.
2. Suppress the material: overcome the traditional mold design structure, open a material gap on the discharge plate (that is, when the mold is closed, the discharge plate and the concave mold are fitted, and the gap between the discharge plate and the concave mold where the material is accommodated) The material thickness is t-0.03 ～ 0.05mm). In this way, the discharge plate moves smoothly during stamping, and the material can be compressed. The key forming part, the discharge plate must be made into a block structure. The metal stamping manufacturer will explain it to you to facilitate the solution of the wear (pressure) damage caused by the pressing part of the discharge plate caused by long-time stamping, and the material cannot be compressed.
3. Add a strong pressure function: that is, increase the size of the pressing part of the discharge insert (the normal thickness of the discharge insert H + 0.03mm) to increase the pressure on the material on the side of the die, thereby suppressing the occurrence of stamping parts during punching Turn material, twist and deform.
4. The edge of the edge of the punch is repaired with a slope or arc: this is an effective method to reduce the buffer 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.
5. Hardware stamping manufacturers explain to you that in the daily production of molds, care should be taken to maintain the sharpness of the edges of punching convex and concave dies. When the cutting edge wears, the tensile stress on the material will increase, so the tendency of the stamping part to turn over and twist will increase.
