    Abstract: A three-dimensionally bending machine comprises a supporting unit to support a workpiece and a feeding unit to feed the workpiece from an upstream side of the workpiece. A heating and cooling unit, provided around the outer circumference of a portion of the workpiece downstream of said supporting unit heats the portion of workpiece in a temperature range for plastic deformation and quenches and rapidly cools the deformed workpiece. A three-dimensionally movable unit, provided downstream of said heating and cooling unit, supports the metal material and controls the supporting position and/or the moving speed of the metal material to apply the bending moment in association with a feed amount, a heating amount, and a cooling amount of the workpiece. Even when a high-strength workpiece is bent, a workpiece having excellent shape fixability and uniform hardness distribution can be made, especially for application to sophisticated automobile parts.

    Abstract: A method of manufacturing a bent metal member comprises supporting the outer surface of a tubular metal material having a Zn-Fe alloy coating layer at two locations spaced in the axial direction of the metal material. The metal material is fed in its axial direction and heated at a position between the two locations to a temperature range of at least the Ac3 point at a heating speed such that the rate of temperature increase is at least 3.0×102° C. per second, held so that the time for which the surface of the metal material is at a temperature of 8.0×102° C. or higher is at most 2 seconds, and then rapid cooled. A bending moment is imparted to the healed portion in two or three dimensions to manufacture a bent metal member having on its surface a Zn-based layer which contains an η, phase.

    Abstract: A bent member having a bent portion with an extremely small bend radius is manufactured by supporting a rectangular tube by a first support means disposed at a first position A while performing relative feeding of the rectangular tube in its lengthwise direction, locally heating the rectangular tube by a heating means disposed at a second position B, cooling the rectangular tube by a cooling means disposed at a third position C, and at the time of working, applying a shear force to the heated portion of the rectangular tube with a shear force applying means 14 disposed in a downstream region D by moving the device 14 two-dimensionally or three-dimensionally simultaneously in the feed direction of the rectangular tube and in a direction generally parallel to a transverse cross section in the lengthwise direction of the rectangular tube which was heated by the heating means.

    Abstract: A method of continuously bending elongated materials may comprise engaging one portion of the elongated material with a guiding means and clamping a second portion of the elongated material in a clamping device driven to rotate with a movable axis of rotation perpendicular to a horizontal plane. A heated zone bounded by a cooled zone moving relative to the elongated material may be established in the material by suitable heating and cooling means disposed adjacent to the material. The elongated member may be driven to pass through the guiding means. Where a hollow elongated material is to be bent, a compressing means may be placed within the elongated material to inhibit deformation of the cross-section of the material. An apparatus for continuously bending elongated members may be comprised of plural means for performing the aforestated functions.
