The Rolling Forming Principle and the Deformation Analysis of the Ring Multi-Mandrel Roller

Abstract:

this paper, focusing on the actuality and the features of the cold ring rolling, studies the forming principle of the rolling of multi-mandrel roller. Through the kinematics analysis of the rolling of ring multi-mandrel roller, the deformation simulation and the mechanical analysis of the infinitesimal gridding strain, this paper builds the infinitesimal deformation model of ring blank’s cold rolling, analyzes the deformation rules of the ring blank’s thickness direction rolled by the multi-mandrel roller and the relation between the tangential strain and the radial strain which should be satisfied by the mandrel roller’s movement values, and deduces out the mathematical expressions of the needed technological parameters like the minimum instantaneous rolling reduction. The research result can be used as the theoretical foundations for designing the multi-mandrel rolling miss and working out the rolling technology of the ring multi-mandrel roller.
