There are several methods of material selection for automobile sheet metal parts fabrication?

Sheet metal fabrication includes traditional laser cutting, cold stamping production and fabrication, bending forming and other methods and main fabrication parameters, as well as various cold stamping die design and fabrication technology main parameters, various machines The equipment principle and control method also include the technology of new stamping die and new technology and new process. After cold drawing the sheet metal, the thickness of the sheet metal auto part can be changed to a more fixed thickness. As everyone knows, different sheet metal materials must be selected for different main purposes.

Under normal circumstances, the raw materials for automobile sheet metal fabrication are mainly divided into the following, stainless steel, copper, aluminum and other raw materials. Different types of sheet metal raw materials must use different production and fabrication methods and different methods.

Stainless steel sheet.

  • (1) Cold rolled steel sheet. Cold-rolled steel plate is mainly a kind of steel plate whose indoor temperature is lower than the work hardening temperature, and then the thinning solution is carried out on it. In cold rolled steel sheets. The surface is relatively smooth and has a uniform thickness, which is not easy to cause a lot of cost, and is very easy to form.
  • (2) Hot-rolled steel sheet: This steel sheet treatment method is mainly to solve the blooming sheet or cast billet. After heating it, phosphorus removal is carried out to produce a rough-rolled steel sheet. Under normal circumstances, there is a slight error in the thickness of the hot-rolled steel plate, and there may be a problem of blank pressing during the specific solution period. The hot-rolled steel plate process is mainly used in the production of parts and components of machinery and equipment such as vehicles, highways and bridges, and ships.

Galvanized steel.

Galvanized steel is mainly hot-dip galvanized on the surface of the steel. Under normal circumstances, the thickness of the hot-dip galvanized layer of the steel plate must be controlled above 10 μm, so as to avoid damage such as corrosion on the surface of the steel plate, mainly used in parts that have great requirements for anti-corrosion.
