英文摘要 | The present paper, which is a continuation to the previous paper, deals with the theoretical and experimental analysis of the rotary phase of the sinter rotary forging. The rotary phase is dealt separately, since mushroom effect during deformation is neglected in the analysis. It is assumed that deformation during sinter rotary forging sinter rotary forging is an incremental process, in which initially a conical indent surface is created during indentation phase by axial movement of the upper conical die. Subsequently, this deformation is swept throughout the perform surface by angular movement of the upper conical die about its axis. The velocity field, stain rates, internal energy dissipation, frictional energy dissipation, frictional energy dissipation and average forging load during rotary phase of the deformation has been formulated in same manner ad done in the part I of this paper with indentation phase. The experiments were conducted using aluminium sintered performs and the results were compared with theoretical ones and were found to be in close agreement. It is assumed that the present work will be a great help in predicting the final rotary forging load and to investigate various deformation characteristics on the design of sinter rotary forging process. |
