Efficient production method and classification of stamping parts

Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with ribs, ribs, rugged or flanging that are difficult to produce by other methods to improve their rigidity. Because of the selection of fine molds, the precision of the workpiece can reach the micron level, and the repeatability is high, the standard is common, and holes, bosses, etc. can be punched. Cold stamping parts are generally no longer processed by cutting, or only a small amount of cutting processing is required. The precision and appearance of hot stamping parts are lower than cold stamping parts, but they are still better than castings and forgings, and the cutting amount is less. Stamping is an efficient production method. The use of composite dies, especially multi-station progressive dies, can complete multiple stamping processes on one press, and complete the entire process from strip uncoiling, leveling, punching to forming and finishing. Produced automatically. 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. Stamping is mainly classified according to the process, which can be divided into two categories: separation process and forming process. The separation process is also called blanking, and its intention is to separate the stamping parts from the sheet along a certain contour line, and to ensure the quality requirements of the separation section. The appearance and internal properties of the sheet material used for stamping have a great influence on the quality of stamping products, and the thickness of the stamping materials is required to be accurate and uniform; the appearance is smooth, without spots, scars, scratches, and no external cracks, etc.; the yield strength is uniform, and there is no obvious Directivity; high uniform elongation; low yield ratio; low work hardening.
