The characteristic application of precision metal stamping parts 'Hardware'

Precision metal stamping parts are the production technology of using the power of conventional or special stamping equipment to directly subject the sheet to the deformation force and deform in the mold, so as to obtain product parts with a certain shape, size and performance. Sheet materials, molds and equipment are the three elements of stamping processing. Stamping is a method of metal cold deformation processing. Therefore, it is called cold stamping or sheet 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 of Universal, 50-60% are made of plates, and most of them are finished products made by pressing. Car bodies, radiator fins, steam drums of steam boilers, container shells, motors, electrical iron core silicon steel sheets, etc. are all stamped and processed. There are also a large number of precision metal stamping parts in instruments and meters, household appliances, office machines, storage utensils and other products. Stamping is an efficient production measure. A compound die is adopted. The exception is a multi-station progressive die. Multiple stamping technology operations can be completed on one press to complete the automatic generation of materials. The production speed is fast, the rest time is long, the production cost is low, and the collective can produce hundreds of pieces per minute, which is loved by many processing plants. Precision metal stamping parts compete with castings and forgings, and have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with reinforcing ribs, ribs, buckling or flanges that are difficult to manufacture by this skilled hand to improve its rigidity. Due to the rejection of rough molds, the precision of the workpiece can reach the micron level, and the precision is high, the specifications are consistent, and holes, bosses, etc. can be punched out. In actual production, process tests similar to the stamping process are commonly used, such as drawing performance test, bulging performance test, etc. to test the stamping performance of the material to ensure the quality of the finished product and a high pass rate. In addition to the hydraulic press for forming the thick plate, the stamping equipment of precision metal stamping parts usually adopts a stagnant press. Focusing on the current high-speed multi-station stagnation press, set up equipment configuration decoiling, finished product collection, transportation and other stagnation, as well as mold library and quick mold change placement, and use computer French tube bundles to form a passive stamping production with high production rate and high production rate. line. Under the condition of producing dozens or hundreds of stamping parts every minute, the stamping and outputting processes are completed in a short period of time, and personal, equipment and quality incidents often occur. Therefore, the safety of stamping is a very important issue.
