Abstract：

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.
