The characteristics of stamping parts

Stamping is power by means of conventional or special stamping equipment, the deformation of sheet metal in the mould is directly force and deformation, thereby gaining a certain shape, size and performance of the production technology of product parts. Sheet metal, stamping mould and equipment is processing of the three elements. Cold stamping processing is a kind of metal deformation processing method. So, called cold stamping or sheet metal stamping, stamping for short. It is plastic metal processing ( Or pressure processing) One of the main methods, also belongs to the material molding engineering technology. 50 ~ 60% of global steel sheet is made, most of this is after squeezing into a finished product. Car body, radiator, the steam kettle drum, container shell, motor, electric iron core silicon steel sheet in stamping process. Instruments and meters, household appliances, office, storage vessels and other mechanical products, there are a large number of stamping parts. Stamping is efficient production, the initiative to adopt composite die, exception is a multi-station progressive die, it can be finished in a pressure on multichannel stamping technical operation, complete material automatically generated. Generate fast, rest time is long, low production cost, collective per minute can be of production, popular with many factories. Stamping parts and castings, forgings, fights has the characteristic of thin, uniform, light and strong. Stamping can make this a master diameter is difficult to manufacture with enhanced, rib flanging, front, or artifacts, in order to improve its stiffness. Rejected due to the rough mould, workpiece precision can reach micron grade, and high precision, specification is consistent, can punching a hole nest, convex sets, etc. In the actual production, commonly used to approximate the manufacturability of stamping process test, such as deep drawing performance test, bulging performance test and other test materials stamping performance, to ensure the quality of the finished product and high qualified rate. Stamping with besides plate with hydraulic press forming, usually take grinds to press. In this high-speed transfer grinds to press as the focus, set up the equipment configuration open book of finished product collection, walks, and quick mold library and placement of the mould, and use computer French bundles, can form high production rate of the passive stamping production line. Per minute in the production of tens or hundreds of stamping conditions, finish stamping in short time, give the process, such as a person, often equipped with and quality incident. Therefore, the safety production in stamping is a very important topic
