Parallel rail type intelligent robot composite bending forming machining method and device

Abstract

The invention discloses a parallel rail type intelligent robot composite bending forming machining method and device. The device comprises two industrial robots, a free bending forming device, a bending forming device, an external clamping guiding device and two ground rails. The free bending forming device and the bending forming device are mounted at the tail ends of the two industrial robots respectively, the industrial robots are mounted on the ground rails, and the two industrial robots are arranged in parallel and can horizontally move along the ground rails respectively. The external clamping guiding device is located between the two industrial robots. By adopting the two industrial robots with the ground rails, the free bending forming system and the bending forming system are mounted at the tail ends of the robots respectively, so that in a bending forming process of a complex space component, a continuous variable curvature radius characteristic can be formed, a small bending radius characteristic can also be formed, and even a bending-torsion composite characteristic can be formed. Frequent die replacement in a single forming mode is avoided, and multi-bending-mode composite integrated short-process forming of a multi-feature complex space pipe fitting is achieved.

AI Technical Summary

Problems solved by technology

[0003] At present, the bending forming technologies of hollow pipe fittings mainly include roll bending, stretch bending, winding bending, push bending and other technologies. If the hollow pipe fittings with complex space axes and continuously changing bending radius are bent by the above-mentioned traditional methods, it is necessary to continuously adapt to different bending characteristics. Replacement of bending forming molds or different forming methods, some even need to be welded after segmented forming, and the dimensional accuracy and forming quality of the formed components cannot be guaranteed, which will greatly increase the complexity of the process, production costs and cycles

The limitations of the traditional bending technology itself make the integrated short-process forming of hollow pipes with complex three-dimensional space configurations very difficult
