In a bending device that has a linear outer mold that is pressed against the workpiece and moves along an outer mold support base with the workpiece, a return plate is fixed to the outer mold, and a piston rod is moved parallel to the direction of movement of the workpiece. The piston rod is made to be movable in the direction of movement of the outer mold during machining prior to machining, and in the opposite direction after machining, and in the opposite direction. A bending device characterized in that it moves together with a return plate when moving in a direction.

する曲げ加工装置。 A circular inner mold that is rotatable and rotates by clamping the workpiece with a vise around it, and a circular inner mold that is pressed against the workpiece to move the workpiece linearly in a fixed direction during machining. In a bending device that has a linear outer die that moves along an outer die support base, a return plate is fixed to the outer die, and a hydraulic cylinder having a piston rod is attached to the outer die in parallel to the direction of movement of the workpiece. It is attached to a support stand, and the piston rod is movable in the direction of movement of the outer mold during processing before processing, and in the opposite direction after processing, and also moves together with the return plate when moving in the opposite direction. A bending device that is characterized by
