Insight into the market situation of stamping dies in Dalian

    The use of stamping die requires high technology, not only to ease the problem, but also to help solve the problem. In the process of stamping production, the size of the super poor is mainly caused by the wear of the die, the bad positioning guide and the deformation of the workpiece. Die wear of the cutting edge will cause the burr is too large or cut the size of the large size, small hole, the flatness of the super poor, should wear or replace the mold. No adverse orientation, including positioning guide pin or other positioning device does not work, feeding machine did not relax, wear the positioning block transfer distance is too long, or the feeding guide plate length not too large clearance. The deformation of parts in the production, the main products such as impact deformation, the blowing pressure is too strong or too large deformation under the gravity impact: material by extrusion or the injury deformation, should promptly clean up the discharge position or increase the discharge space: Top improper deformation.

    When installing the concave and convex die, there should be a uniform blanking clearance, to ensure the stamping quality and prolong the service life of the stamping die. The assembly sequence of the upper and lower dies shall be determined according to the die structure, and the different installation methods can be determined separately for the mould installation of the guide pillar and the guide pillar. For complex stamping die installation, the reasonable assembly sequence is determined according to the limited size of the upper and lower die parts. As an indispensable technology and equipment, the stamping die is a technology intensive product. Stamping parts quality, production efficiency and production costs, and mold design and manufacturing have a direct relationship. The use of stamping materials, performance, the use of the mold parts, when the material is pressed by the hard or deformation resistance of the larger, the convex die, concave die selection of good wear resistance, high strength of the material. When drawing stainless steel, aluminum bronze die can be used, because it has good resistance to adhesion. The guide sleeve is required to wear resistance and good toughness, so the use of low carbon steel surface carburizing and quenching.
