Stamping parts knowledge
Stamping parts are the production technology of parts with a certain shape, size and performance by means of the power of conventional or special stamping equipment, so that the plate is directly subjected to the deformation force and deformation in the mold. Sheet material, die and equipment are the three elements of stamping processing. Stamping process is a cold deformation process of metal. Therefore, it is called cold stamping or sheet stamping, referred to as stamping. It is one of the main methods of metal plastic processing (or pressure processing), also belongs to material forming engineering technology.
50 to 60 percent of Global steel is made from sheet metal, most of which is finished by pressing. Automobile body, radiator sheet, boiler drum, container shell, motor, electrical core silicon steel sheet, etc. Instruments, household appliances, office machines, storage vessels and other products, there are also a large number of stamping parts. Stamping is an efficient production measure, adopt composite die, anomaly is multi-station progressive die, can complete multi-channel stamping technical operation in a press to complete the automatic generation of materials. Production speed, long rest time, low cost, more than hundreds of pieces per minute collective production, is loved by many processing plants.
Stamping parts and castings, forgings, there is thin, uniform, light, strong characteristics. The workpiece with reinforcing bars, ribs, bending or flanging, which is difficult to manufacture in this familiar diameter, can be produced by stamping to improve its rigidity. Due to the rejection of rough mold, workpiece accuracy can reach micron level, and high precision, consistent specifications, can be stamped out of the hole, boss, etc. In the actual production, the technology test similar to the stamping process is commonly used, such as deep drawing performance test, swelling performance test and so on to check the stamping performance of materials, so as to ensure the quality of finished products and high pass rate.
Stamping equipment in addition to the thick plate with hydraulic forming, usually use a stagnant press. To the world's high-speed multi-station stagnation press as the focus, set the equipment configuration of uncoiling, finished product collection, delivery and other stagnation as well as mold library and fast mold change placement, and the use of computer French tube bundle, can form a high production rate of passive stamping production line.
