Metal stamping parts is a production technology that uses the power of conventional or special stamping equipment to directly deform the sheet metal in the mold and deform it, 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, simply
Called stamping. 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, 50-60% are made of plates, most of which are finished products after stamping. The body of the car, radiator fins, steam drums of boilers, shells of containers, iron core silicon steel sheets of motors, electrical appliances, etc. are generally stamped. There are also a large number of metal stamping parts in products such as instruments and meters, household appliances, office machines, and storage utensils. Stamping is an efficient production process
The measure is to adopt a composite die, especially a multi-station progressive die, which can complete multi-channel stamping technology operations on one press and complete the automatic generation of materials. The production speed is fast, the working time is long, the production cost is low, and the collective can produce hundreds of pieces per minute, which is favored by many processing factories.
Compared with castings and forgings, metal 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. With modern high-speed multi-station hydraulic presses as the core, it is equipped with unwinding, finished product collection, conveying and other machines, as well as mold libraries and quick mold change devices, and is controlled by computer programs, which can form passive stamping production with high productivity Wire. Dozens or hundreds of pieces of hardware are produced per minute
In the case of stamping parts, the processes of stamping and output are completed in a short period of time, and personal, equipment and quality accidents often occur.
