摘要：

针对异形截面环件在实际轧制过程中影响因素较多、规律复杂、环件质量较难保证等问题，结合径向轧环轧制特点，提出径向封闭轧制成形工艺。以异形截面盾构机滚刀刀圈体为研究对象，借助立式轧环机、1000 t压机等设备，从工艺方案制定、轧制工艺参数选择、坯料形状设计、模具结构设计、轧制孔型安装调试等方面对轧环质量的影响进行了分析。结果表明：当轧制比为1.2~4.0、环件毛坯与锻件体积近似相等、环坯各截面圆滑渐变、毛坯内孔上下端面设置倒角,并且于轧制前将导向轮尽可能靠近环件、轧制后驱动辊多轧制几圈予以修型，可以消除环件的毛刺缺陷，提高了环件的综合力学性能、缩短生产周期、降低生产成本。

Aiming at the problems of many influencing factors, complex laws and difficulty in ensuring the quality of the ring with special-shaped section in the actual rolling process, a radial closed rolling process was proposed by combining the characteristics of radial ring rolling. For the hob ring body of special-section shield machine, the influences of process scheme formulation, rolling process parameters selection, blank shape design, die structure design, rolling groove installation and debugging etc. on the rolling ring quality were analyzed by vertical ring rolling machine, 1000 t press and other equipments, The results show that when the rolling ratio is between 1.2 and 4.0, the volume of ring blank approximates to the forgings volume, the cross sections of ring blank are smooth and gradual, the upper and lower end faces of inner holes for blank are chamfered, the guide wheel is as close to the ring as possible before rolling, and the driving roller is rolled several times after rolling to be modified, the vertical thorn defect of ring can be eliminated, the comprehensive mechanical properties of ring is promoted, the production cycle is shorten, and the production cost is reduced.
