摘要：

回弹对于线材折弯加工的精度影响非常明显，为探索线材回弹规律，建立了线材折弯过程的数学模型，以材质45钢的线材为研究对象，进行有限元分析与试验研究。验证了有限元分析与试验方法获得回弹角度数据的一致性，考虑折弯角度和线材直径两个主要参数对回弹的影响，建立了线材折弯回弹角度的双参数数学模型。将回弹角度双参数数学模型应用于弯丝机的补偿模块，进行线材折弯试验，取得明显的折弯补偿效果，使线材折弯加工精度达到了1°，实现了对任意折弯角度和线材直径的线材折弯回弹补偿。

It is evidently shown that the springback has an influence on the accuracy of wire bending process. In order to explain the law of springback, a mathematical model of wire bending process was built for 45 steel wire, and finite element analysis and experimental research were carried out. The consistence of springback angle was attained through the finite element simulation and experiments. Considering the influence of the two main parameters of bending angle and wire diameter, a double-parameter mathematical model of springback angle was established. When the double-parameter mathematical model was applied to the compensation module of wire-bending machine for the test of wire bending, a prominent compensation effect was achieved, the processing precision was up to 1° with the springback compensation of arbitrary bending angle and wire diameter realized.
