Summary:PROBLEM TO BE SOLVED: To provide a bending device for a pipe joint capable of bending it at an arbitrary angle at piping construction site without causing deformation and crush of the inside of the pipe joint and flattening it. SOLUTION: This bending machining device for the pipe joint is composed of a first holding mechanism 14 for holding a one end part of the tubular pipe joint 2 turnably, a second holding mechanism 16 for holding the other end part of the pipe joint turnably, and a jack-up mechanism 18 for pushing up a part to be bent and machined of the pipe joint and bending it at a predetermined angle. Consequently, bending is performed at an arbitrary angle at the piping construction site without causing deformation and crush of the inside of the pipe joint and flattening it.
