Metal stamping is a forming method that uses presses and dies to apply external force to plates, strips, pipes, and profiles to cause plastic deformation or separation, so as to obtain workpieces (metal stampings) of the desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively called forging. The stamped blanks are mainly hot-rolled and cold-rolled steel plates and strips. Precision stamping is mainly classified according to process, and can be divided into two categories: separation process and forming process.
Metal stamping parts are mainly formed by stamping metal or non-metallic sheet material with the help of the pressure of the press, and it has the following characteristics:
⑴ Precision metal stamping parts are manufactured by punching under the premise that the material consumption is not large. The parts are light in weight and good in rigidity. After the plastic deformation of the sheet metal, the internal structure of the metal is improved, making the metal stamping parts The intensity has increased.
⑵Metal stamping parts have high dimensional accuracy, are uniform in size with the mold parts, and have good interchangeability. No further mechanical processing is required to meet general assembly and use requirements.
⑶During the precision stamping process of metal stamping parts, since the surface of the material is not damaged, it has better surface quality and a smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, plating and other surface treatments.
Below you are some Feature application for precision stamping parts:
Metal stamping parts are powered by conventional or special stamping equipment, so that the sheet metal is directly deformed and deformed in the mold, so as to obtain the production technology of product parts with a certain shape, size and performance. Sheet metal, mold 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 metal stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to the material forming engineering technology.
50-60% of the steel is made of sheet metal, most of which are finished products after pressing. Car body, radiator sheet, steam drum of steam boiler, shell of container, iron core silicon steel sheet of motor, electrical appliances, etc. are usually processed by stamping. There are also a large number of metal stamping parts in products such as instruments, household appliances, office dullness, and storage utensils. Stamping is an efficient Linyi action. It adopts a compound die. The abnormality is a multi-station progressive die. It can complete multiple stamping techniques on a single 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 collective can produce hundreds of pieces per minute, which is loved by many processing plants.
Metal stamping parts are strong against castings and forgings, and have the characteristics of thin, uniform, light and strong. Stamping can produce a workpiece with reinforcement, ribs, bending or flanging that is difficult to manufacture with this familiar diameter, so as to increase its rigidity. Due to the rejection of the rough mold, the precision of the workpiece can reach the micron level, and the precision is high and the specifications are consistent. It can punch out the holes, bosses, etc. In actual production, common technical tests similar to the stamping process, such as drawing performance test and bulging performance test, are used to check the stamping performance of the material to ensure the quality of the finished product and a high pass rate.
Except for the forming of thick plates with hydraulic presses, stamping equipment usually adopts stagnation presses. Focusing on this world's high-speed multi-station stagnation press, setting equipment configuration such as uncoiling, finished product collection, delivery and other stagnation, as well as mold library and quick die change placement, and using computer French tube bundle, can form a high stamping rate and high passive stamping stamping line. Under the condition of dozens or hundreds of metal stampings per minute, the stamping and output processes are completed within a short time, and personal, equipment and quality changes often occur.
