| Abstract: | Force of tube extrusion has been studied theoretically and the formula is determined by means of block method. On the basis of theoretical and experimental study, It is found that theoretical results of extrusion force given by calculating formula are approaching to that of experiment and relative errors are less than 20%. It is also found that extrusion force has relation to deformation temperature, lubricant and ratio of extrusion. The following calculating formula of extrusion force is given by this paper. |
