Abstract

The invention discloses a special pipe expanding machine which comprises a rack, a material ejection oil cylinder, a connecting rod, a propelling oil cylinder, a hole expanding shaft and a punch. A roller way in the horizontal direction is arranged in the rack, so that a work-piece works between the material ejection oil cylinder and the propelling oil cylinder. A left supporting frame and a right supporting frame are transversely arranged at one end, close to the material ejection oil cylinder, of the rack. A material ejection frame parallel to the left supporting frame and the right supporting frame is arranged on the rack. One end of the material ejection frame is connected with a push rod of the material ejection oil cylinder, and the other end of the material ejection frame is connected with a material ejection fixing rod. A heating ring is arranged in the material ejection fixing rod. The special pipe expanding machine is simple in structure, high in safety and high in efficiency, and feeding operation can be carried out continuously.
