| 目的 研究成形工艺参数对薄壁件多道次旋压变形均匀性的影响。 方法 采用试验的方法,研究了双轮数控旋压成形铝合金薄壁件过程中,旋压间隙 δ、进给率 f 和旋轮圆角半径 R 等关键工艺参数,对制件表面质量和壁厚均匀性的影响。 结果 3 个工艺参数都对制件表面质量和壁厚均匀性有影响。 结论 减小旋压间隙 δ、采用较大的主轴转速 S 和较小的进给率 f 可提高零件的表面质量和尺寸精度。 改善零件壁厚分布的均匀化程度,适当提高旋轮圆角半径 R,也能使变形的均匀化程度提高。 |

| Objective To study the effects of forming parameters on the macro deformation uniformity of the thin-walled aluminum parts during multi-pass spinning process. Methods The influences of spinning gap δ, feed rate f, and spin roller fillet radius R on the quality of the part surface and the uniformity of wall thickness were experimentally investigated in the formation process of thin-walled aluminum parts using double wheeled spinning machine. Results All thress forming parameters had influence on the quality of the part surface and the uniformity of wall thickness. Conclusion The results showed that the surface quality, size precision and thickness uniformity of the parts were improved by decreasing the spinning gap δ, or using a higher spindle speed S with a lower feed rate f . And a bigger spin roller fillet radius also resulted in much more uniform deformation. |
