Procedimiento para la producción de componentes endurecidos en prensa |
摘要 |
<p>The method for the production of car body component of a motor vehicle from a plate made of untempered, heat formable steel plate, comprises forming and hardening the plate in a press tool to sheet-metal profile. The plate is provided, whose geometry corresponds to the development of the finished component and subsequently the plate is remodeled and press-hardened in a hot working tool to component, which is provided with a surface coating. The component is cooled during press-hardening at 200[deg] C. The surface coating is applied through a diffusion process. The method for the production of car body component of a motor vehicle from a plate made of untempered, heat formable steel plate, comprises forming and hardening the plate in a press tool to sheet-metal profile. The plate is provided, whose geometry corresponds to the development of the finished component and subsequently the plate is remodeled and press-hardened in a hot working tool to component, which is provided with a surface coating. The component is cooled during press-hardening at 200[deg] C. The surface coating is applied through a diffusion process with a heat treatment of the component in which the component is applied in contact with a metal powder. The diffusion process is carried out at 350-410[deg] C and the heat treatment is carried out over a period of 0.25-3.0 h. The coated component is cooled after the heat treatment at 200[deg] C. The cooling of the component is carried out under inert-gas atmosphere. The plate is perforated before or after the forming process. The press-hardening is carried out so that the areas emerge with different stabilities on the component.</p> |
