| Abstract: | The relationship between the minimum deformation power and the approach angle (α) of drawing dies is analysised in this article and also the relationship between the pressure on the surface of dies hole (Km) and approach angle (α) and reduction rate (γ),drawing force with approach angle (α) is analysed The infection on the life of drawing dies by the pressure on the surface of dies hole is researched,The minimum approach angle (α) with minimum drawing force is obtained. |
| Keywords: | caculation of power and force approach angle (α) reduction rate (γ) life of drawing dies. |
