The invention relates to the technical field of rail transportation, and discloses an adjustable rail bending machine. The adjustable rail bending machine comprises a machine body. An ejector is movably installed at one end of the machine body. A supporting rod is fixedly installed in the middle of the machine body. A regulating box is fixedly installed at the other end of the machine body. A hydraulic ejection device is movably installed inside the regulating box. A transmission sleeve is fixedly installed on the side, on the back face of the machine body, of the regulating box. The inner ring of the transmission sleeve is movably connected with an adjusting hand wheel in a sleeving mode. An oil cavity is formed in the hydraulic ejection device. The inner ring of the top of the oil cavityis movably connected with a rotating ejection rod in a sleeving mode. The front face of the oil cavity is movably connected with a piston ejector in a sleeved mode. A threaded hole groove is formed in the rotating ejection rod, and the inside of the threaded hole groove is movably connected with a threaded rod in a sleeving mode. The middle of the inner wall of the regulating box is movably connected with a toothed belt in a sleeving mode. Due to the fact that the adjustable hydraulic ejection device is arranged to be matched with uniform compression rapid pressure relief, and thus the rail bending machine is convenient to use, high in efficiency and longer in service life.
