Introduction to the importance of metal stamping processing

In the automobile production industry, automobile bodies, chassis, fuel tanks, radiator fins, boiler drums, container shells, motors, electrical iron core silicon steel sheets, etc. are all stamped and processed. There are also a large number of stamping parts in products such as instruments, household appliances, bicycles, office machinery, and living utensils. Compared with castings and forgings, precision stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with stiffeners, ribs, undulations or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision molds, the accuracy of the workpiece can reach the micron level, and the repeatability is high, the specifications are consistent, and holes, bosses, etc. can be punched out. The surface and internal properties of the sheet metal used for stamping have a great impact on the quality of the stamped product. The metal stamping process has the following requirements for the stamping material: 1. The thickness of the stamping material is accurate and uniform; 2. The surface is smooth and clean, without spots, scars, and scratches. No damage, no surface cracks, etc.; 3. Uniform yield strength without obvious directionality; 4. High uniform elongation; 5. Low yield ratio and work hardening. Stamping is an efficient production method. Using compound dies, especially multi-station progressive dies, multiple stamping processes can be completed on one press to realize the process from strip uncoiling, leveling, punching to forming and finishing. Fully automatic production. The production efficiency is high, the working conditions are good, and the production cost is low. Generally, hundreds of pieces can be produced per minute.
