Abstract：

Drawing and forming die is one of the widely used technologies in stamping,with which various shapes of open hollow parts can be made.Internally acting forces of blank designs are rather complicated during the process of drawing and forming die,so it is difficult to analyze the potential quality problems of complicated parts in this process.Regarding the difficulty that complicated shell bottom can not be formed by one drawing,a solution was found in this paper through technological analysis and adjustment of the die.The structure of drawing and forming die for the auto vacuum booster shell was designed,and the figures were shown for each drawing of the shell center.The products manufactured by the die can fully meet the technical requirements and bring favorable economic benefits.
