    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: Aluminium panels curved in mutually orthogonal x, y and z dimensions are made by stretch forming. A former (34) for use in this process comprises a plurality of steel bars (60) extending generally in the y direction and mutually spaced apart in the x direction. The bars (60) are held in side rails (62) and (64), which are formed with holes (66) to receive the bars (60), and flexed over an intermediate rail (68). Thus each bar (60) is curved in a yz plane. The holes (66) and the seats for the bars on the intermediate rail (68) each lie on a curve in an xz plane. So located, the bars (60) combine to define an envelope which is curved in mutually orthogonal x, y and z dimensions. When an aluminium sheet is stretched over the former (34), it takes up the shape of this envelope. The invention also relates to a method of forming from sheet material a curved panel.

    摘要: A die assembly for draw stamping sheet metal in a press has an upper die structure and a lower die structure, each constructed and arranged to be mounted on a press for reciprocal movement therebetween. The upper die structure and the lower die structure have complementary stamping surfaces for stamping sheet metal to a desired configuration. A clamping assembly and a stretching assembly grip the sheet metal along opposite sides of the complementary stamping surfaces and drivingly move apart pre-stretching the sheet metal as the upper die structure and the lower die structure are closed to stamp the sheet metal to the desired configuration.

    摘要: Beschrieben wird ein Streckbiegeverfahren zur Biegung von Hohlprofilen und die entsprechende Profildorn-Streckbiegemaschine, wobei das Verfahren vorsieht, daß das Hohlprofil symmetrisch von beiden Seiten her von den Enden ausgehend gleichzeitig in X-Y-Richtung unter Vorspannung gebogen wird, wobei das jeweilige Biegewerkzeug feststeht und das Hohlprofil in X-Y-Richtung mit einer verfahrbaren Einspannstelle um das Biegewerkzeug gebogen wird, wobei die Einspannstelle zusätzlich auch in Torsions-Richtung verschwenkbar ausgebildet ist. Das Hohlprofil kann nach einem weiteren Verfahren auch um eine Biegeschablone gebogen werden. Ein zusätzliches Verfahren sieht vor, daß das Hohlprofil von den Enden her auf Kernwerkzeuge aufgewickelt wird und zusätzlich ein Preßstempel auf die Längsrichtung des Hohlprofils wirkt.

    摘要: Contoured shapes, especially elongated saddle-section shapes such as helicopter rotor blade erosion shields, are formed from a sheet metal workpiece by providing the workpiece with lateral flange portions that are engaged with respective lateral tools movable in synchronism adjacent to the flanks of an elongate male tool so as to draw the workpiece, by its flange portions, over the male tool and into contiguity therewith. The lateral tools may cooperate with gripper means to grip the flange portions and facilitate stretch-forming. Apparatus for performing this method is also disclosed.
