Production process of steel wire for vehicle seat frame

Production process of steel wire for automobile seat frame.
The process includes the following steps: wire surface treatment, initial drawing, normalizing, semi-finished wire surface treatment, subsequent drawing, oiling, packaging.
The intermediate normalizing treatment is adopted in the invention. The surface treatment and multiple drawing process of the wire rod and semi-finished steel wire before and after the normalizing treatment can effectively reduce the scratches, scratches, ears and other surface defects carried by the wire rod;
The anti-rust ability of steel wire can be significantly improved by electrolytic phosphating.
Drawing soap powder is used in front of the drawing, with good lubrication performance and less carrying capacity on the wire surface.
The last drawing process uses flow dynamic drawing oil as lubricant, which can not only reduce the soap powder and oil stains carried on the steel wire surface, but also make the color of the steel wire surface more uniform.
Therefore, the steel wire used for seat skeleton produced by using the process of the invention has good welding effect, strong rust prevention ability, excellent surface quality, and mechanical properties to meet the use requirements of customers.
