发明名称 BENDING DEVICE FOR BEND WORKING OF PIPE
摘要 A bending device for the pipe bending process is provided to increase the bending efficiency in the molding of various shapes of double pipes and to increase the formability. A bending device for the pipe bending process comprises: a clamp fixing a pipe and in which an axis of rotation is bent to the center; and a bending region supporting member(100) inserted into the bending region of the pipe bent by the clamp. If tensile force is provided to the longitudinal direction, a bending region supporting part(110) of the bending region supporting member is extended toward the external diameter corresponding to the inside diameter of the pipe. If the tensile force is canceled, the bending region supporting part is elastically restored.
