Abstract: The theory and technology of cross wedge rolling (CWR) used in manufacturing non-rotating shafts represents the innovative and breakthrough development of Finish-approaching Forming Technology, and the profile surface of die is the key of the methodof non-rotating shafts with cross wedge rolling. The new method of non-rotating shafts with cross wedge rolling is proposed on the basis of analysis of the forming principle of non-rotating shafts with CWR. Then, the profile surface of die is derived according to conjugate relationship of rolling process. Finally, forming experiments are carried out on the rolling mill. The results show that the workpiece has no obvious defect and the main dimensional accuracy meets the requirements. So the method proposed is an excellent way of manufacturing eccentric shafts with fewer cutting process, improved working conditions, higher material utilization and lower energy consumption.
