强力旋压工艺参数的选择对于成形产品的尺寸精度具有直接影响。以强力旋压的连杆铜衬套为研究对象,选择减薄率、旋轮工作角、旋轮圆角半径和进给比作为优化性试验因素,以旋压后连杆衬套筒形件的壁厚差和扩径量作为评价指标,设计正交试验并对试验数据进行分析。通过田口算法对强力旋压参数进行优化,得到减薄率为30%、旋轮工作角为15°、旋轮圆角半径为10 mm、进给比为0.5 mm/r的优化参数组合。
The choice of strong spinning process parameters has a direct impact on the dimensional accuracy of the shaped product. Taking the copper rod bushing with strong spinning as the research object, choosing the thinning rate, working angle of roller, radius of rounding wheel and feeding ratio as the optimization test factors, Of the wall thickness difference and the amount of expansion as the evaluation index, design orthogonal test and test data analysis. The optimized spinning parameters were optimized by Taguchi algorithm, and the optimal combination of parameters was obtained with 30% reduction rate, 15 ° rotation angle, 10 mm rotation radius and 0.5 mm / r feed ratio.
