| 英文摘要 | 金属线材成形零件种类繁多,其加工成形受到几何参数变化、材料特性等不同因素影响,致使加工精度难以准确控制。针对平面螺旋线材零件的圆弧半径变化现象提出了一种基于迭代思想的误差修正方法。通过分析加工对象的几何特性,建立了线材成形半径、弯曲角度以及线材送料长度三者之间的几何关系模型,建立了加工时送料轴与推弯轴的函数关系;以等半径线材圆弧零件的成形工艺为例,提出了平面螺旋线材的半径误差修正方法,并进行了试验加工,该方法能够有效提高线材加工精度。; Forming parts of metallic wire are widely used,but its machining accuracy is difficult to be controlled because of the comprehensive influence of geometric parameters,material properties and other factors.For this phenomenon,an error correction method based on iterative mechanism was proposed by changing the radius of the planar spiral wire parts.Firstly,the geometric relationship among the wire forming radius,cumulative bending angle and wire feed length was derived by analyzing the geometric characteristics of the object to be processed.And then,the formula between the feed axis and the push bending axis was constructed.Finally,the radius error correction model of planar spiral wire was established and applied to the forming process of wire parts with equal radius.The machining result shows that the proposed method could improve the accuracy of wire processing effectively.; 国家科学技术部支撑项目(SQ2009GJC4001675) |
