Stamping is to rely on press and die for sheet, strip, pipe and profiles, such as external force, make its produce plastic deformation or separation, thus to obtain the required shape and size of the workpiece,
The forming method.
Stamping and forging belong to plastic processing (
Or pressure processing)
, called the forging press.
Stamping of billet is mainly hot rolling and cold rolling steel plate and steel belt.
Steel all over the world, there are 60 ~ 70% is plank, most of which is made by stamping products.
Car body, chassis, fuel tank, radiator fin, the boiler steam drum, container shell, motor, electric iron core silicon steel sheet stamping processing.
Instruments and meters, household appliances, bicycles, office machinery, and other products, also have a large number of stamping parts.
Stamping is power by means of conventional or special stamping equipment, the deformation of sheet metal in the mould is directly force and deformation, thereby gaining a certain shape, size and performance of the production technology of product parts.
Sheet metal, stamping mould and equipment is processing of the three elements.
Cold stamping processing is a kind of metal deformation processing method.
So, called cold stamping or sheet metal stamping, stamping for short.
It is plastic metal processing (
Or pressure processing)
One of the main methods, also belongs to the material molding engineering technology.
Cold stamping generally no longer by machining, or only need a small amount of machining.
Hot stamping precision and surface state is lower than the cold stamping parts, but it's still better than the castings, forgings, cutting processing capacity.
Stamping parts mainly is the metal or nonmetal sheet, with the aid of the pressure of the press, through the stamping die stamping forming, mainly has the following features: 1.
Stamping parts is on the premise of material consumption is not big, created by the stamping, light weight, good stiffness, its parts and sheet metal after plastic deformation, metal internal organizational structure to improve, to improve strength of stamping parts.
Stamping parts with high dimensional accuracy, with the module size uniformity, good interchangeability.
Don't need to be further mechanical processing to meet the requirements of the general assembly and use.
Stamping parts in stamping process, due to the surface of the material are not destroyed, therefore, have good surface quality, smooth and beautiful appearance, for the surface paint, electroplating, phosphating and other surface treatment provides a convenient conditions.
