Paper Title:
Deformation Behavior of Spirogyrate Ring for Cold Ring Rolling
  Abstract

Based on the platform ABAQUS, a 3-D FEM model of spirogyrate ring rolling process has been developed to investigate the ring’s deformation behavior and the expansion law of the diameter. According to the FEM analysis, this kind of profile ring rolling process can be divided into two phases, i.e. the profile forming phase and the diameter increasing phase. During the former phase, the deformation of spirogyrate ring focuses on the profile formation and the diameter increases slowly. In the latter phase, the ring diameter expands rapidly. FEA illustrates that the material flowing to the outer diameter areas is greater than that towards the inner diameter areas in the profile forming phase. The maximum PEEQ is in the pit of the outer profile, whereas the minimum PEEQ locates near the end face. The variation of outer and inner diameter of the spirogyrate ring shows monotonic increasing trend during the whole ring rolling process, in which the expanding rate of inner areas is greater than that of the outer areas.
