Abstract：

Based on the forming theory of 3D free bending for metal tube, the process optimization of free bending for 6061 aluminum spiral tube was investigated to improve the complexity and efficiency in the manufacture, and an optimized process scheme changing the angle of each swing of bending die was proposed based on the process analysis of free bending. Then, the simulated forming of spiral tube before and after process optimization was achieved by software ABAQUS, and the optimized results were demonstrated. At the same time, the free bending experiment of 6061 aluminum spiral tube was conducted, and the results matched the simulation were obtained. Thus, the optimized experiment works well, and the manufacturing quality of spiral tube is improved obviously. Furthermore, the reliability of the process optimization of free bending for 6061 aluminum spiral tube was verified. The single swing angle of bending die is 3.3° by the optimized free bending equipment.
