10. A method for using a pipe bending machine, characterized in that: The method is applied to a pipe bending machine as claimed in any one of claims 1 to 9, comprising the following steps: S1: conveying pipe fittings: placing pipe fittings in the storage bin (201) so that the pipe fittings are located in the conveying groove (204), and by starting the rotating motor (206) on the mounting frame (205), the active dial (207) can be driven to rotate, so that the active dial (207) drives the cylindrical pins (208) to sequentially enter the movable grooves (210) on the groove wheel (209), and as the cylindrical pins (208) move, the groove wheel (209) can be driven to rotate, driving the rotating shaft (202) to rotate in the storage bin (201), causing the movable block (203) to rotate, thereby conveying the pipe fittings to the interior of the loading frame (301), thereby realizing the conveying of the pipe fittings; S2: Cleaning the pipe fittings: Start the electric telescopic rod (302) to allow each fixed rod (311) to enter the interior of the pipe fittings, then start the forward and reverse motor (304) to drive the first gear (305) to rotate, which can drive the second gear (306) to drive the rotating wheel (307) to rotate, and each cam hole (308) drives the moving shaft (309) to move, and the moving shaft (309) drives the fixed rod (311) to slide in the guide wheel (310), so that each fixed rod (311) moves away from each other, which can squeeze the interior of the pipe fittings and fix the pipe fittings. The rotating motor (312) is started to drive the rotating platform (313) to rotate, which can drive the pipe to rotate in the feeding frame (301), and the vacuum cleaner (402) is started to suck away impurities on the pipe through the vacuum pipe (401). At the same time, the rotating brush head (403) can be used to brush away particle impurities on the outer surface of the pipe. Then, the electric telescopic rod (302) is started again to push the pipe into one of the cleaning cylinders (408). The cleaning cylinder (408) wipes the surface of the pipe to improve the cleaning effect of the pipe, so as not to affect the bending accuracy and appearance quality of the pipe; S3: Tube bending: After passing through the cleaning cylinder (408), the tube enters the interior of the feeding platform (501), is fixed by the chuck (503), and then the moving cylinder (502) is started to transport the tube to the tube bending device (6), which then bends the tube.
