[0002] When a metal rod or pipe fitting is bent, oxides on the surface of the metal part are likely to fall off under the influence of bending. These debris are not easy to clean up when they fall on the workbench. Moreover, if the debris is not cleaned up and accumulates, during the processing activity, the debris is likely to pierce into the human epidermis when it comes into contact with the human body, causing hazards such as infection. Therefore, we propose a bending equipment with a function of extracting bent and fallen debris, which can clean up this part of the debris. Content of the Utility Model
