What are the requirements for the metal stamping process?

With the continuous advancement of technology, metal stamping parts have penetrated into various fields and are closely related to our lives. So what are the metal stamping process requirements? First, the raw material properties of metal stamping parts 1. Material inspection The raw materials of metal stamping parts should have a quality certificate, which ensures that the material meets the specified technical requirements. When there is no quality certificate or due to other reasons, the metal stamping parts factory can select raw materials for re-inspection as needed. 2. Hardness testing The hardness testing of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be tested with other testing instruments. 2. Process requirements of metal stamping parts 1. When designing the structure and shape of parts, the metal stamping adopts simple and reasonable surfaces and combinations. At the same time, it should try to minimize the number of processed surfaces and the smallest processing area. 2. The requirements of its forming performance. In order to facilitate the stamping deformation and the improvement of the quality of the parts, the material should have good plasticity, a large plate thickness directivity coefficient, a small plate directivity coefficient, and the yield strength and elastic modulus of the material. The ratio is small. The separation process does not require a material with good plasticity, but a material with a certain degree of plasticity. 3. The cost of metal stamping parts increases with the improvement of accuracy, especially in the case of high accuracy, this increase is extremely significant. Therefore, high accuracy should not be pursued when there is no sufficient basis. Similarly, the surface roughness of metal stamping parts should also be adjusted appropriately according to the actual needs of the mating surface. Three, the selection principle of metal stamping oil 1. Silicon steel strip: Silicon steel strip is a material that is relatively easy to punch. Generally, for the easy cleaning of the finished product, low-viscosity punching oil will be used on the premise of preventing punching burrs. 2. Carbon steel strips: Carbon steel strips are mainly used for low-precision processing such as protection plates of some mechanical equipment and other processes that do not require high technical requirements. Therefore, the first thing you should pay attention to when selecting stamping oil is the viscosity of the drawing oil. 3. Galvanized steel bar: Galvanized steel bar is a welded steel plate with a hot-dip galvanized or electro-galvanized layer on the surface. Because it reacts chemically with chlorine-based additives, it should be noted that the chlorine-based stamping oil may cause white The problem of rust. 4. Copper and aluminum alloy strips: Because copper and aluminum have good ductility, when selecting stamping oil, you can choose stamping oil that contains oily agents and good sliding properties. Avoid using chlorine-containing added stamping oil, otherwise the stamping oil will corrode Discoloration of the surface appears. 5. Stainless steel: Stainless steel is a material that is prone to work hardening. It is required to use drawing oil with high oil film strength and good sintering resistance. Generally, stamping oil containing sulfur and chlorine compound additives is used to avoid problems such as burrs and cracks on the workpiece while ensuring the extreme pressure processing performance. The metal stamping process is more complicated. In order to ensure that the performance of the hardware product can meet the requirements of use, it is necessary to follow the corresponding process requirements to ensure the feasibility of production. A precision stamping factory and a team of mold design engineers with 20 years of experience in metal stamping processing have broken through the technical difficulties in the stamping industry, and can mass produce in-mold automatic riveting parts, automatic in-mold tapping parts, and precision stamping in-mold injection terminals.
