Abstract：
|
|
Sized sheet is often used to make the automobile side-members by the processes of blanking,piercing and forming with large presses and dies.Stamping process characteristics of the side-member were analyzed,and the blanking and bending composite die structure as well as design features were introduced.Stamping process was forecasted with FE(finite element)software Dynaform and phenomenon of wrinkle and crack were checked during the stamping process of the sheet.The reasonable solutions were made at last.
