摘　　要：为提升异型薄壁法兰产品的生产效率,实现快速、高效、精密生产,提出了基于金属材料连锻连轧工艺的随形成形方法。分析了连锻预成形过程和连轧精密成形过程,设计了出坯模具和环轧机轧辊型腔模具。将连铸坯热锻下料改为外购方矩坯精确下料,坯料加热后,采用出坯模具在连锻过程中进行预成形,使用轧辊型腔模具在环轧机连轧时进行高精度成形。通过试制验证,持续对轧辊型腔尺寸进行研究和优化,以确定适合的工艺参数和生产工艺,产品锻件最终合格率达到98.82%,证明基于金属材料连锻连轧工艺的随形成形方法可靠,可以为异型薄壁法兰的精确成形和高效生产提供有效的技术支持。In order to improve the production efficiency of special-shaped thin-walled flange products and achieve fast,efficient and precise production,the conformal forming method based on the continuous forging and rolling process of metal materials was proposed,and the preforming process of continuous forging and the precision forming process of continuous rolling were analyzed.Then,the blank die and the roller cavity die of the ring rolling mill were designed,and the hot forging blanking of the continuous casting blank was changed to the precise blanking of the outsourced square rectangular blank.Furthermore,after the blank was heated,the blank die was used for preforming during the continuous forging process,and the roller cavity die was used for high-precision forming during the continuous rolling of the ring rolling mill.Through trial production verification,continuous research and optimization of roller cavity size is conducted to determine suitable process parameters and production process,and the final qualification rate of product forgings reaches 98.82%,proving that the conformal forming method based on the continuous forging and rolling process of metal materials is mature and reliable.Thus,it provides effective technical support for the precise forming and efficient production of special-shaped thin-walled flanges.
