8. A method of bending an adjustable three-dimensional pipe bending apparatus according to any one of claims 1 to 7, comprising the steps of:
step one: firstly, placing a pipe fitting (18) to be bent on a buffer inclined plane (17), wherein the pipe fitting (18) at the lowest side is in pressing contact with the inner wall of a guide side plate (14), and under the pushing of a feed pushing rod (16), an auxiliary pushing block (15) can push the corresponding pipe fitting (18) to the position of a guide assembly (19);
step two: under the action of the compression adjusting piece, the compression traction seat (36) moves towards the central shaft position of the through hole (55), so that the pipe fitting (18) with different diameters can be subjected to bending fit, and friction force between the compression traction wheel (33) and the pipe fitting (18) can be used for pushing and guiding the pipe fitting (18);
step three: the electromagnetic heating ring (26) is used for heating the pipe (18), so that the plastic property of the pipe is improved;
step four: under the promotion of adjusting the impeller, roof pressure post (53) is along second slip cap (52) to perforation centre of a circle position slip to adjust the radius of pressing of roof pressure ball (54), under the drive of rotating electrical machines (41), drive gear (42) and transmission tooth anchor ring (43) cooperate, thereby drive rotatory support pressure seat (46) and rotate fast, just so make the strong point of a plurality of roof pressure balls (54) rotate fast and form a closed buckling ring, then drive buckling ring through upset driving piece and buckle pipe (18).
