First, the stamping part is the power of the conventional or special stamping equipment, so that the sheet material is directly subjected to the deformation force in the mold and deformed, thereby obtaining the production technology of the product parts of 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.

Second, stamping parts application

It is one of the main methods of metal plastic processing (or pressure processing) and is also part of material forming engineering technology. Of the global steels, 50 to 60% are made of sheet metal, most of which are finished products 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 initiative. It adopts a composite mold. The abnormality is a multi-station progressive die. It can complete multiple stamping operations on one press to 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 to improve 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.

Stamping equipment is usually equipped with a condensing press in addition to a 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 the personal, equipment and quality events often occur. Therefore, safety in stamping is a very important topic.

Third, the characteristics of stamping parts

The stamping parts are mainly formed by stamping and stamping metal or non-metal sheets by means of the pressure of the press. The main features are as follows:

The stamping parts are made by stamping under the premise of low material consumption, the parts are light in weight and good in rigidity, and after the sheet material is plastically deformed, the internal structure of the metal is improved, and the strength of the stamping parts is improved. .

The stamping parts have high dimensional accuracy, uniform size with the same module, and good interchangeability. General assembly and use requirements are met without further machining.

In the stamping process, since the surface of the material is not damaged, it has a good surface quality and a smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatment.
