Materials generally selected for auto stamping parts a large number of cold stamping processes are used in the production of automobile stamping parts, which is suitable for the needs of multi-variety and mass production of automobile stamping parts industry.
It is a forming processing method that applies external force to plates, strips, pipes, profiles, etc. by presses and molds to cause plastic deformation or separation, so as to obtain workpieces (stamping parts) of the required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips.
Among the steel products in the world, 60-70% are plates, most of which are stamped into finished products. The body, chassis, fuel tank, radiator fins of the car, the steam drum of the boiler, the shell of the container, the iron core silicon steel sheet of the motor and electrical appliances, etc. are all stamped.
The selected material should first meet the performance requirements of auto parts; the selected material should have better technical performance; the selected material should have a better economy.
Cold stamping materials are closely related to the production of automobile stamping parts. The difference in material level determines the performance of the product, and directly affects the process design of the automobile stamping process, affecting product quality, cost, service life, and production organization. Therefore, a reasonable choice of materials is an important and complex task.
