Claims

[Scope of utility model registration request]

A ring plate rotatably supported about the axis in a plane orthogonal to one axis, a mechanism for driving the ring plate at least 180 degrees forward and reverse, on the ring plate, Each pair of heads are slidably held in the diametrical direction of the ring plate, each pair of heads is installed between the heads and the outer periphery of the ring plate, and each pair of heads is operated to face each other so as to be close to each other and to be separated from each other. a hydraulic mechanism, a pair of cutting cutters each mounted on a drive shaft supported parallel to the rotation center axis of the ring plate at each opposite end of the head, and driven in a plane parallel to the plane of the ring plate; and a bevel cutter, and a guide roller is provided at the tip of each head to which the cutter is attached, which guides the head along the circumferential wall surface of the steel pipe when the ring plate rotates in contact with the circumferential wall surface of the steel pipe. The steel pipe is moved in the longitudinal direction along the axis of rotation and carried into the center hole of the ring plate, the cutting dimensions are measured, and the steel pipe is clamped by the entry and exit clamping devices, and then the cutting cutter is driven. , operate the pair of cutter head moving hydraulic mechanisms to advance the heads toward the peripheral wall of the steel pipe, cut and cut the peripheral wall of the steel pipe with the cutting cutter, rotate the ring plate 180 degrees forward or reverse, and then again. activating the hydraulic mechanism;
While returning the cutter head to its old position, while driving the bevel cutter, a pair of hydraulic mechanisms for moving the cutter head are operated, and the cutter forms a welding bevel on the end face of the steel pipe, and at the same time, the ring plate is moved 180 degrees. A steel pipe cutting and beveling machine that is characterized by rotating in reverse or forward direction to form a uniform and accurate welding bevel along the cut end surface.
