| Description | Journal: Iop Conference Series: Materials Science and Engineering Flexible-bending, as a new bending technology, is widely used in the processing of profiles and tubes, especially in the production of small batches and multi-curvature. In flexible-bending process of tubes, the stress is complex and the springback problem exists which affects the forming accuracy and quality of bent tubes. In this paper, the springback is studied and solved by springback compensation by means of finite element numerical simulation and experimental verification. The results show that the wall thickness of tubes and the bending radii have important influence on springback. Springback compensation can effectively solve the problem of forming error caused by springback because that the forming radii after compensation can approach the target radius gradually. The experiments were carried out with flexible-bending equipment. The simulation results were in agreement with the experiments, which proved the reliability of the simulation. |
