Abstract：

This paper deduce the critical condition of non\|innerwrinkling in process of drawing tapered part by innerwrinkling model,geometry conditions and stress analysis;By programming, the drawing time\|ralative thickness curves are drawn under different parameters;The embodying time of innerwrinkling formation is gained via these curses and the effects on time are analyzed. The criterion of non\|innerwrinkling without blankholder are acquired in process of drawing tapered part .Moreover,these curves are being generality,they can be reference on production or theory.
