Abstract：

On the basis of ordinary rotary rolling technology, a new technology for forming super-large circular plate, namely multi-roller rotary rolling technology, was proposed, which had the advantages of labor-saving, energy-saving, high product dimensional accuracy, etc. and was especially suitable for manufacturing super-large circular plate. Firstly, the forming principle of the multi-roller rotary rolling technology was introduced, and the design method of die, process and blank related parameters for the multi-roller rotary rolling was analyzed based on geometry and plastic forming principles. Finally, the super-large circular plate forming by multi-roller rotary rolling was numerically simulated and analyzed by finite element analysis software Deform-3D to verify the correctness of the given parameter design method, and the evolution rules of shape, outer diameter, strain and forming load for workpiece in the roller rotary rolling process of the super-large circular plate were analyzed. The results show that the multi-roller rotary rolling technology is reliable and provides a method for the direct forming of super-large circular plate.
