摘要：

在强力反旋管型件时，旋轮直接与管型件相接触，因此，旋轮参数的选择很大程度上决定了管型件的成形质量。以QSn70.2管型件为研究对象,以成形质量为评价指标，对管型件进行错距反旋，利用Simufact进行有限元仿真。通过灰色关联法优化旋轮参数，得出各旋轮参数对管型件成形质量的影响程度。结果表明，对于反旋管型件的成形质量，旋轮参数影响顺序依次为：旋轮工作圆弧半径、旋轮轴向错距、旋轮工作角。优化后的旋轮参数为轴向错距5 mm，工作角18°，工作圆弧半径5 mm。对此组旋轮参数组合进行实验验证，得到的管型件成形质量显著提高。

When the tube part is strongly antispun, the rotating roller directly contacts with the tube part, and the selection of spinning roller parameters largely determines the forming quality of tube part. For tube part of QSn70.2, taking the forming quality as the evaluation index, the offset antispinning of the tube part was simulated by Simufact, and the parameters of spinning roller were optimized by the grey correlation method to obtain the influences of spinning roller parameters on the forming quality of tube parts. The results show that the order of influence of the spinning roller parameters on the forming quality of antispinning tube part is spinning roller working arc radius >spinning roller axial offset > spinning roller angle. Furthermore, the optimal parameters of spinning roller are axial offset of 5 mm, working angle of 18° and working arc radius of 5 mm. The optimized combination of spinning roller parameters is verified, and the forming quality of tube part is significantly improved.
