Deformation behaviors and conditions in L-section profile cold ring rolling

摘要

Three-dimensional FE model of plastic penetration in L-section profile cold ring rolling is established under ABAQUS software. Based on this model, the expanding rules of plastic zone in roll gap are revealed by FE simulation, and three deformation behaviors of L-section ring that exist in the rolling process are exposited. Conditions for three deformation behaviors are studied and verified by rolling simulation and experiment. The deformation behavior, which is needed for normal rolling of L-section ring, and its conditions are determined at last.
