Forming and use of stamping parts
The stamping part is a forming method of a workpiece (stamping part) of a desired shape and size by applying an external force to a plate, a strip, a pipe, a profile, and the like by a press and a die to cause plastic deformation or separation. Stamping and forging are the same plastic processing (or pressure processing), collectively called forging. The stamped blanks are mainly hot rolled and cold rolled steel sheets and strips.Of the world's steel, 60 to 70% are sheets, most of which are stamped into finished products. The body, chassis, fuel tank, radiator piece of the automobile, the steam drum of the boiler, the casing of the container, the iron core silicon steel piece of the electric motor and the electric appliance are all stamped and processed. There are also a large number of stamping parts in instruments, household appliances, bicycles, office machinery and other products.
The stamping part is a production technology of a product part which is subjected to deformation force and deformation in a mold by means of power of a conventional or special stamping apparatus to obtain a shape, a size and a 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 material forming engineering technology.
Cold stampings are generally no longer machined or require only a small amount of machining. The accuracy and surface condition of hot stampings are lower than that of cold stampings, but they are still superior to castings and forgings, and the amount of cutting is small.
The stamping parts are mainly formed by stamping and stamping metal or non-metal sheet materials by means of the pressure of the press. The main features are as follows:
1. 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.
2. 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, so that the strength of the stamping parts is improved. improve.
3. 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.
