FEM Simulation on Cold Rolling of Outer Spherical Bearing Ring

Abstract

Ring rolling theory based on completion of the mold, rough and technical parameters of the design, application Abaqus software to build three-dimensional model of rolling, and the use of Abaqus / Explicit algorithm of external spherical bearing outer ring of cold ring rolling simulation and analysis come to different mold shape, size, structure and guide roller feed specifications on the forming process, reveals a spherical bearing outer ring of the mechanism of cold ring rolling, gets die structure is different, different size core roller, guide rollers with different combinations of cold rolling play a crucial role in forming quality. At the same time by rolling the solution results demonstrate the power of cold ring rolling of the nonlinear characteristics. Revealed the ring rolling process is a complex interaction of multi-parameter deformation coupling.
