The production of metal stamping parts, what are the taboos in the use of stamping materials + raw materials use national standard original factories

The technicians responsible for the production of metal stamping parts said that the selection of materials in stamping dies is very important because it directly determines the final quality of the product. Xiaoshuo summarized the taboos in the use of common stamping materials, and let’s take everyone to understand them together: 1. The punching process of brittle and hard materials should not be used for punching, blanking and trimming. It is not suitable to use brittle and hard materials. Materials with too high hardness. The more brittle the material, the more likely it is to tear during punching; if the material is too hard, such as high-carbon steel, the flatness of the cross section of the president is very large, which is especially serious for thick materials. The material with good elasticity and high flow limit can get a good section. Especially soft materials such as low-zinc brass can be punched out smooth and small inclination section. 2. High elastic materials should not be used in the bending process. High elastic materials should not be used in the bending process. The greater the elasticity of the material, the greater the rebound of the formed part to its original state after bending, which will cause the workpiece to fail to reach the predetermined shape, requiring multiple mold trials and mold repairs. The material used in the bending process should have sufficient plasticity, a lower yield point and a higher modulus of elasticity. The former guarantees no cracking, and the latter makes it easy for the workpiece to reach an accurate shape. The most suitable materials for bending are mild steel, pure copper and pure aluminum. 3. Materials with poor plasticity should not be used in the drawing process. Materials with poor plasticity should not be used in the drawing process. Since the allowable degree of deformation of low plastic materials is small, it is necessary to increase the number of drawing processes and intermediate annealing. The material for deep drawing requires high plasticity, low yield point and good stability. The smaller the ratio of the yield point of the drawn material to the tensile strength, the better the drawing performance and the greater the limit of one deformation. The materials commonly used for deep drawing are low carbon steel, low zinc brass, pure aluminum and aluminum alloy, and austenitic stainless steel. 4. Cold extrusion process should not use materials with high strength and low plasticity. Cold extrusion process should not use materials with high mechanical strength and low plasticity to avoid increasing deformation resistance and cracking. Cold extrusion requires materials with high plasticity, low yield point and low work hardening sensitivity. The most suitable materials are pure aluminum and aluminum alloy, brass, tin phosphor bronze, nickel, zinc and zinc cadmium alloy, low carbon steel and so on. Hardware, 15 years of focusing on the production of metal stamping parts, 20,000+ sets of customized production experience in stamping dies, monthly processing capacity of 100+ sets of molds, hundreds of precision processing production equipment, daily production capacity of 3 million punches, and silk-like stamping accuracy up to 0.01 mm, the raw materials are imported and the original national standard factory, and 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
