Research on stamping process of lower section of back door outer plate and back section of head cover
The stamping process was studied for the lower section of back door outer plate and back section of head cover.The two parts of the back door outer plate and two parts of the lower part of the back door plate were obtained by using the splicing process and the double-groove pro-cess in the primary stamping process.The draw bead with high resistance was used in the drawing process to avoid the unstable quality of the final parts caused by the unstable material inflow in the production process,which ensured the precision of mould and part,improved the production effi-ciency and reduced the production cost.
