special customized cold heading die punch punch pin needle
Main components and material selection of cold heading molds
1. Main components of cold heading molds: Cold heading molds mainly include upper and lower molds, mold cores, and mold seats. The upper and lower molds are used to clamp metal materials and complete the forming process through the clamping action, while the mold core is used to support and form the internal structure of the material.
2. Material selection for cold heading molds: The materials for cold heading molds need to have high hardness, high strength, good wear resistance, and fatigue performance. Common cold heading die materials include alloy steel
High speed steel, hard alloys, etc.
3、 The manufacturing process of cold heading molds
l Design of Cold Heading Mold: The design of cold heading mold needs to meet the technical and process requirements of the product, including the structural shape, dimensional accuracy, surface smoothness, etc. of the product. When designing, it is necessary to consider factors such as the strength, stiffness, and temperature changes of the mold.
l Processing technology of cold heading molds: The processing technology of cold heading molds includes rough machining, heat treatment, precision machining, assembly, and debugging. Among them, heat treatment is crucial for improving the hardness, wear resistance, and fatigue performance of the mold.
