Abstract : The high manufacture precision of the brake shield with thickness of 2 5 mm plicated shape used in
electric car was satisfactory using exact stamping technique. A feasible forming technique was framed , and one multi
ple posite die was designed in order to plish the punching , extending , cutting and forging base on
the analysis and account for the configuration and stamping technology of brake shield. posite die structure ,
stamping process of brake shield and key point of die designing were introduced. The obtained moulds are permitted to
be used in real production and the products are satisfactory.
Keywords : brake shield ; composite die ; extending ; forging
