PIPE MACHINING DEVICE AND METHOD

摘要

The disclosed pipe machining device (10) is provided with: a heating coil (13) that heats a heated section (S) of a bellows pipe (B); conveyance mechanisms (14, 15) that convey the bellows pipe (B); and a control unit (16) that controls the conveyance mechanisms (14, 15). The conveyance mechanisms (14, 15) also function as a compressive-force-applying means that applies compressive force in the axial direction of the bellows pipe (B). The control unit (16) controls the conveyance mechanisms (14, 15) in a manner so that the pipe (P) is conveyed by a distance each time that is twice the pitch of a wave-shaped corrugation that is continuously formed to the bellows pipe (B).
