高周波加熱管曲げ装置。 In a high-frequency heating tube bending device equipped with an annular water-cooled tube dual-purpose coil having a water outlet, the water-cooled tube dual-purpose coil is coaxially spaced from each other with a plane of symmetry substantially perpendicular to the axis of the tube to be processed. An annular nozzle having an inner surface with the same diameter as the inner surface of the water-cooled pipe-combined coil is installed in close contact between the water-cooled pipe-combined coil. A high frequency heating tube bending device characterized in that a predetermined pattern of air grooves facing outward in a radial direction at a predetermined angle are provided symmetrically to the symmetry plane.
