Abstract
A tube bending device having draw-bending and compression-bending functions and capable of bending in all processes in a unit of device is provided. The device performing bending by rotating the tube at a predetermined angle with the tube pressured against a circumferential surface of a bending die, the device including a movable type of tube bending unit movable in a longitudinal direction of a tube to be processed or a fixed type of tube bending unit and a tube twisting unit for rotating the tube freely at a predetermined angle with a center of the tube being an axis core is characterized in that the tube bending unit has one or both of draw-bending and compression-bending functions and is provided rotatably in a vertical plane about an axis parallel to the axis core of the tube so that the displacement amount in a tube twisting operation can be reduced.
