摘要：

在普通摆辗技术的基础上，提出了一种超大型圆盘件成形新技术——多辊摆辗技术。该技术具有省力、节能、产品尺寸精度高等优点，特别适用于制造超大型圆盘件。首先介绍了多辊摆辗技术的成形原理，然后，借助几何学与塑性成形原理对多辊摆辗的模具、工艺及坯料相关参数的设计方法进行了分析，最后，使用有限元分析软件Deform-3D对多辊摆辗成形超大型圆盘件进行了数值模拟分析，从而证明了所给参数设计方法的正确性，并且分析了多辊摆辗超大型圆盘件成形过程中的工件形状、工件外径、工件应变以及成形载荷的演变规律。研究结果表明，多辊摆辗技术的可靠性高，可为超大型圆盘件的直接成形提供方法。

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.
