A kind of stamping process for micro motor metal shell was analyzed and a set progressive blanking die was designed. Though the die structure was relatively complicated,the safety feed was realized and the breakage of the middle or“off the bottom” were avoided using the“ manipulator” feeding , and the bright shell surface, uniform wall thickness were obtained.The die is easy to be manufactured,and has a long life,with whom the high-quality parts are obtained and high productivity is achieved. The die can be a reference for the same kind.
