摘要：

为了研究对轮旋压成形机理，突破对轮旋压成形精度控制技术，采用有限元方法分析了道次减薄率、进给比、旋轮成形角以及内旋轮圆角半径等工艺参数对旋压件圆度、直线度及壁厚差的影响。结果显示：当道次减薄率Ψt=20%～30%、进给比f=1.5～2.0 mm·r-1、旋轮成形角αρ=25°、内旋轮圆角半径rρ内=10 mm时，旋压件成形精度最高。同时，分析了在总压下量为9 mm时，内、外旋轮在不同压下量下对成形精度的影响。结果表明：当外旋轮压下量为5 mm、内旋轮压下量为4 mm 时，旋压件精度最高。最后，通过工艺实验验证了有限元仿真结果的准确性，结果显示两者偏差小于15%。

In order to study the forming mechanism and breakthrough precision control technology of counter-roller spinning, the influences of process parameters such as pass thinning ratio, feeding rate, forming angle of roller and radius of inner roller on the roundness, straightness and wall thickness difference of spun part were analyze by the finite element method. The results show that when the pass thinning ratio Ψt is 20%-30%, the feeding rate f is 1.5-2.0 mm·r-1, the forming angle of roller αρ is 25°, the radius of inner roller rρ内 is 10 mm, the forming accuracy of spun part is the highest. At the same time, the influences of different reduction amounts of inner and outer rollers on forming accuracy were analyzed when the total reduction amount is 9 mm. And the results show that the spun parts have the highest precision when the reduction amount of outer roller is 5 mm and reduction amount of inner roller is 4 mm. Finally, the accuracy of the finite element simulation results is verified by the spinning experiment, and their deviation is less than 15%.
