The stamping part is a production technology of a product part which is deformed by a deformation force in a mold by means of power of a conventional or special stamping apparatus, thereby obtaining a certain shape, size and performance. Sheets, molds and equipment are the three elements of stamping. Stamping is a method of cold deformation 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) and is also part of the material forming engineering technology.
Of the global steels, 50 to 60% are made of sheet metal, most of which are finished products that have been stamped and pressed. The body of the car, the radiator piece, the steam drum of the steam boiler, the casing of the container, the iron core silicon steel of the electric motor and the electric appliance, etc. are all stamped and processed. There are also a large number of stamping parts in instruments, household appliances, office dulls, storage utensils and other products. Stamping is an efficient Linyi move. It adopts a composite mold. The abnormality is a multi-station progressive die. It can complete multiple stamping operations on one press and complete the automatic generation of materials. The production speed is fast, the rest time is long, the cost of Linyi is low, and the group can be used for hundreds of pieces per minute, which is loved by many processing factories.
Stamping parts are competitive with castings and forgings, and they are thin, uniform, light and strong. Stamping can produce a workpiece with ribs, ribs, curls or flanging that is difficult to manufacture in order to increase its rigidity. Due to the rejection of the rough mold, the precision of the workpiece can reach micron level, and the precision is high and the specifications are the same, and the hole, the boss and the like can be punched out. In actual production, the process test similar to the stamping process, such as the drawing performance test and the bulging performance test, is used to test the punching performance of the material to ensure the quality of the finished product and high qualification rate.
The stamping equipment is usually equipped with a condensing press in addition to the thick plate hydraulic press. Focusing on the current high-speed multi-station condensing press, setting equipment configuration unwinding, finished product collection, guarantee delivery and other stagnation, mold library and quick mold change placement, and using computerized tube bundles, can form a high-passivity passive punching Linyi line. In the case of dozens of punches and hundreds of stampings per minute, the process of stamping and unloading is completed in a short period of time, and personal, equipment and quality events often occur. Therefore, safety in stamping is a very important topic.
