Abstract:

The Mandrel radial speed and driving roll rotational speed have a directly influence on the complex ring rolling process. The design of Mandrel radial speed and driving roll rotational speed through traditional physical experiments is expensive and inefficient. This study discusses the finite element modeling technology about ring rolling process, performs the simulation based on the Simufact software, and analyzes the influence of Mandrel radial speed and driving roll rotational speed on rolling force and equivalent plastic strain. The results show that the deformation of ring die is adequate and uniform at a mandrel radial speed of 2mm/s and a driving roll rotational speed between 25rad/s-33rad/s, where the rolling force is suitable with good forming effect. Result of simulation will provide a reference for the design and improvement of process parameters of ring rolling process.
