摘要： Provided is a bending apparatus 1 for a plate-shaped metal workpiece 3, including a suction device (suction pad) configured to suck a surface of a plate-shaped metal workpiece 3 in a removable manner; a plurality of expansion and contraction devices 20A-20G (servo screw jacks) each including the suction device mounted on a distal end thereof and being capable of expanding and contracting a length ranging from a proximal end thereof to the suction device and an apparatus base (bed) on which the proximal end of each of the expansion and contraction devices is mounted. The bending apparatus 1 is configured to form the plate-shaped metal workpiece 3 under bending deformation by expanding and contracting the expansion and contraction devices under a state in which the suction device sucks the surface of the plate-shaped metal workpiece 3.

摘要： A stretch-forming apparatus includes a main frame which carries a die enclosure between jaw assemblies. An insulated die is mounted in the enclosure. A method of forming a component includes placing a workpiece in the enclosure, heating the workpiece to a working temperature using electrical resistance heating, and then stretching the workpiece against the die. The method is particularly useful for titanium workpieces.

摘要： Disclosed is apparatus (1) and methods for the stretch forming of an elongated hollow metal section (6), such as an aluminium extrusion. The apparatus and methods use a flexible constraining means (15) which surronds at least a portion of the outer periphery of the elongated hollow metal section (6) to constrain and support the walls of the elongated hollow metal section (6) against the forces produced within the interior of the hollow metal section (6) during the reshaping of the extrusion by the stretch forming operation. The apparatus and methods disclosed herein resist wrinkles, crimps and bulges being formed in the walls of the elongated hollow metal section (6) during the stretch forming and reshaping thereof.

摘要： Methods for making curved pieces from continuous metal elements are provided. Such methods include advancing a continuous metal element through a calendering station such that each length of the element assumes a pre-established curvature; stopping advancement of the element after a curved length thereof has passed through a wrap-bending station located downstream of the calendering station; wrap-bending the length of the element located at the station, while simultaneously conveying the curved portion to a stretch-bending station; stretch-bending the curved portion; resuming advancement of the element until the wrap-bent length is at a cutting station; and cutting the element in the wrap-bent length, thus producing the desired curved piece. Curved pieces produced by such methods are also provided.
