Abstract：

The accuracy of the inversion tube on die with axial pressure is analysed.A drawing-inversion tube die is designed.It's charactenstic and work principle and design main points are introduced.The geometrical and mechanical conditions are determined.The equation for determining inversion Tube load also is proposed by theoretical analyses.The comparison of the theoretical calculation and experiment results of inversion tube process of LF21M tube shows that equation presented in this paper is rational.The high quality invesion tube can be obtained by using this kind of die.The results can be used for determining the drawing-invesion tube process and die design.
