Abstract
Multi-wedge Cross Wedge Rolling (MCWR) is an advanced technology in forming long axial parts, and it does not have the disadvantages of Single-wedge Cross Wedge Rolling (SCWR).However, it is extremely important to realize the regularity of the displacement on the end-section of the rolled parts in MCWR due to the complexity of its forming mechanism. In this paper, based on the method of the displacement on the end-section of the rolled parts in SCWR, the rules of the displacement on the end-section of a typical rolled part in MCWR were investigated theoretically, and the curve on the end -section of the rolled part in MCWR were analyzed.Based on the curve, the regularity of metal flowing and the characteristic of forming for the typical rolled part in each phase by MCWR were analyzed. It is of high value in studying the forming mechanism and designing mould and technics in MCWR.
