Abstract：

A new technology for eccentric shaft of jaw crusher was proposed. By using finite element method of Deform-3D software, the cross wedge rolling of forming eccentric shaft of jaw crusher was simulated, the deformation process, and the distribution of strain and the technology characteristics of eccentric shaft of jaw crusher were analyzed. Simulation results indicate that the new methodology of cross wedge rolling of eccentric shaft for jaw crusher is feasible; when the concentric shaft becomes the eccentric shaft, metal equivalent strain in non rolling zone is larger, up to 1.8 at the beginning of deformation. The raw material has larger contact deformation when it comes into contact with the roller base circle and guide plate, and these should be controlled by taking measures. The result provides a theory foundation for forming large-sized eccentric shaft with high efficient and saving energy.
