Abstract: Taking the inner plate of the upper beam on the automotive front door frame as an example, based on the Autoform R6 software, the hot forming process and the simulation analysis method were expounded. Finally, the problems in the hot forming process and the treatment methods were summarized, and the influence of holding pressure on cooling rate was studied.
