Abstract：

In this paper,the kinetically admissible continuity velocity field and its relevant velocity discontinuity of open die cold extrusion without mandrel for the thick walled tube are built based in the determination of the equation of stream function.The simplified and available model of velocity discontinuity and the method of obtaining the inner border line are provided,which is suitable for the technique,by the analysis of three kinds of velocity discontinuity.
