The characteristic application of stamping parts. Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet to deformation force and deform in the mold, so as to obtain product parts of a certain shape, size and performance. Sheet metal, mold and equipment are the three elements of stamping processing.
Stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet metal stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to material forming engineering technology. Among the steel products in the world, 50-60% are made of plates, and most of them are finished products through stamping and pressing.
Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with reinforcing ribs, ribs, coils or flanging, which are difficult to manufacture, in order to improve their rigidity.
Due to the rejection of the rough mold, the precision of the workpiece can reach the micron level, and the precision is high and the specifications are consistent, and holes, bosses, etc. can be punched out. In actual production, technological tests similar to the stamping process are commonly used, such as deep drawing performance test, bulging performance test, etc. to test the stamping performance of materials to ensure the quality of finished products and a high pass rate. Stamping equipment usually adopts stagnation presses except for thick plates formed by hydraulic presses.
