| The work aims to propose a new method of axial/radial sequential rolling of the profiled ring, establish an intelligent finite element model for the process, and clarify the thermo-mechanical coupling plastic deformation behavior during the process. With the rolling of large wind power bearing rings as the research object, the principle of the sequential axial/radial rolling process was clarified and an intelligent finite element model for the process was established based on the Abaqus/Explicit platform. In the new method of axial/radial sequential rolling of the process, the end face rolling of the axial tapered rollers was first performed to gather materials at both ends of the ring blank, completing the volume pre-distribution of the initial rectangular blank. Then, it was seamlessly switched to the radial rolling stage of the profiled ring. Finally, the profiled ring with complex cross-sections was formed. A set of rolls and a single heat process were used to achieve the precise forming of the profiled ring. The method and model for controlling the movement of the rolls during the axial/radial sequential rolling process were proposed, an intelligent simulation model for this process was established, and the process tests were conducted to verify the prediction accuracy of the model. Furthermore, it simulated and clarified the plastic deformation behaviors such as temperature, strain, and rolling force during this process. The new axial/radial sequential rolling technology for profiled rings can achieve high-quality, short-process, high-efficiency, and low-cost green manufacturing of large wind power bearing rings. The established intelligent simulation model lays an advanced simulation technology platform for the optimum design of this process. |
