Abstract:
Provided are: a pipe-bending mold unit capable of appropriately performing bending work on a pipe without the risk of wrinkles occurring; and a pipe-bending machining device comprising said unit and having easy setup changes. A bending mold (100) comprises: a gripping member (10) having, in the outer circumferential surface thereof, a first groove section (11) that has a semi-circular cross-section, said gripping member also having a recessed engagement section (12) formed inside the first groove section and extending for a first prescribed distance in the circumferential direction inside a plane orthogonal to the axis of rotation (A); and a pressuring member (20) having in the outer circumferential surface thereof a second groove section (21) that has a semi-circular cross-section, said pressuring member also having a protruding engagement section (2) extending for a second prescribed distance in the circumferential direction from a tip section of the second groove section. The protruding engagement section is fitted into the recessed engagement section and a pipe reception groove having a semi-circular cross-section is formed by the first groove section and the second groove section. The pressuring member and the gripping member are coupled by a hinge joint having the axis of rotation as the center thereof and are relatively and rotatably supported, around the axis of rotation.
