Abstract

The invention relates to a method for improving wear resistance of a hardware stamping die. The die comprises a stamping table and a wear-resistant part, wherein the wear-resistant part comprises the following components in parts by weight: 60-70 parts of cast tungsten carbide with the particle size of 20-200 meshes, 3-10 parts of cast stone powder, 6-15 parts of porcelain clay, 3-8 parts of a binder and 3-6 parts of sodium silicate; and the surface of the wear-resistant part is subjected to laser shot peening treatment. The method solves the technical problems that in the prior art, the wear rate of a stamping head is large, cracks are generated through hardening treatment, and the strength is insufficient.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a method for improving the wear resistance of metal stamping dies. Background technique [0002] Stamping die is a special process equipment that applies pressure to the material to cause separation or plastic deformation to obtain the required parts or products. Compared with traditional mechanical processing and production, stamping technology has the advantages of saving materials and energy, and high efficiency, and is widely used. Stamping production is mainly for sheet metal. Through molds, blanking, punching, forming, stretching, trimming, fine blanking, shaping, etc. can be made. Due to the generally large production batches of stamping parts and the high working temperature of stamping, the surface of the stamping die often suffers from wear, oxidation, or oil contamination, which leads to the quality and appearance of the stamped workpieces not up to standard. During sta...
