Investigation of the method of rotary swaging under the conditions of large strains

Abstract

 The results of computer simulation of rotary forging using figure dies at given (45°- 90°) angles of rotation of the workpiece prior to each treatment cycle are presented. On the basis of the obtained results the conclusions were made about the rational use of rotary forging for production of a homogeneous strain with the level of accumulated strain of ??1,0, when necking the workpiece does not exceed 30% of the original, which is important for subsequent processing steps in order to accumulate high levels of deformation without the active reduction of the original section.
