摘要： A machine for cutting or beveling a pipe. A cutter unit rotates around the pipe while cutting any surface of the pipe after gripping and fixing the pipe. The machine includes: a main body which a pipe passes through the center portion thereof to be fixed; and a cutter unit coupled to the main body unit rotates around the fixed pipe to cut or bevel the pipe. The cutter unit may have a rotating unit on one side to pull the cutter unit aside and a locking unit on the other side to restrain or release the cutter unit. An entry control unit operating the cutter unit includes: a lever gear-engaged with an outer side surface of an entry control plate; and a clutch formed on a rotation shaft of the lever such that the restraint is released when the lever is lifted or pressed in the axial direction.

摘要： Disclosed are a power transfer device for transferring external power to a rotary body, a pipe cutting device using the power transfer device and a hydraulic chucking device using the power transfer device. The power transfer device is configured to transfer external power to a rotary body coupled to one side of a main body. The power transfer device includes at least one double-action interlocking cylinder mounted to a rear surface of the rotary body and provided with a rod protruding toward the main body, a push unit installed in the main body and provided with at least one pusher protruding toward the rotary body, and a bearing disposed between the pusher of the push unit and the rod of the interlocking cylinder and configured to allow relative rotation of the pusher and the rod and to transfer power between the pusher and the rod.

摘要： Disclosed is an orbital cutting apparatus that is capable of freely and selectively controlling forward and backward movement of a plurality of cutting tools, allowing the cutting tools to move forward and backward and to move in an axial direction of a material to be cut so as to enable processing of various shapes as well as cutting and chamfering, and is capable of simultaneously carrying out cutting and chamfering operations for a pipe material or a heavy pipe having a thickness of dozens of mm or more.
