Stamping parts is a forming and processing method that applies external force to sheets, strips, pipes and profiles by means of presses and dies to cause plastic deformation or separation to obtain workpieces of desired shape and size.
1. Characteristics of stamping parts
(1) Stamping parts are made by stamping under the premise of low material consumption. The parts are light in weight and good in rigidity. After the sheet is plastically deformed, the internal structure of the metal is improved, which improves the strength of the stamped parts. .
(2) It has high dimensional accuracy, is uniform in size with the module, and has good interchangeability. No further machining is required to meet general assembly and use requirements.
(3) During the stamping process, 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, phosphating and other surface treatments.
2. Application of stamping parts
Of the steel in the world, 50-60% are made of sheets, most of which are finished products that have been pressed. Car body, radiator fins, steam drums of boilers, shells of containers, iron core silicon steel sheets of motors and electrical appliances, etc. are all stamped and processed. There are also a large number of stamping parts in products such as instrumentation, household appliances, office machines, and storage utensils. Stamping is an efficient production method, using composite molds, especially multi-station progressive molds, which can complete multiple stamping technical operations on one press to complete the automatic generation of materials. The production speed is fast, the rest time is long, the production cost is low, and the collective can produce hundreds of pieces per minute, which is favored by many processing plants.
