| Abstract: | Velocity field and drawing force of tube dieless drawing have been studied theoretically and the formula is determined by means of upper boundary method.On the basis of theoretical and experimental study,It is found that theoretical results ofdrawing force given by calculating formula are approaching to that of experiment and relative errors are less than 15%.The formula in this paper can be used to calculat the drawing force during tube dieless drawing.It is also found that drawing force has relation to de... |
