    摘要： An apparatus and method for forming a power transmission member from a thin-walled blank, the apparatus including a pair of dies (84) having opposed work surfaces, and a mandrel (50) positioned between the work surfaces of the dies (84) for receiving a blank (52) to be formed and rotated upon movement of the work surfaces of the dies in opposite directions during a forming operation. The mandrel (50) includes a work surface for cooperating with the work surface of the dies (84). Notch forming projections (70) on the work surfaces of the dies (84) cooperate with the work surfaces of the mandrel (50) for roll punching notches (72) through the blank (52) as the blank (52) is rotated between the moving dies (84).

    摘要： Apparatus is provided for piercing and flanging a metal workpiece. The apparatus includes a punch and a back-up die with the punch driven by a hydraulic ram. The punch, die, and ram are mounted on a frame which is movably carried by a main support. A workpiece support is affixed to the main support and positions the workpiece between the punch and the die. The ram moves the punch toward and away from the workpiece relative to the frame and also causes the frame to move relative to the workpiece. This arrangement enables the punch and die to seek operative positions relative to the workpiece without the necessity of the workpiece being precisely positioned. The punch and die are also designed to be reversed to provide the opposite operation on the workpiece, if desired.

    摘要翻译： 提供用于刺穿和翻边金属工件的装置。 该装置包括冲头和备用模具，其中冲头由液压压头驱动。 冲头，冲头和冲头安装在由主支撑件可移动地承载的框架上。 工件支撑固定在主支架上，并将工件定位在冲头和模具之间。 柱塞相对于框架将冲头移动和离开工件，并且还使框架相对于工件移动。 这种布置使得冲头和模具能够相对于工件寻找操作位置，而不需要精确地定位工件。 如果需要，冲头和模具也被设计成反向以在工件上提供相反的操作。

    摘要： An elongated continuous steel round bar is cut to a specified length, and the cut piece is pressed by forging machine to form a workpiece including an annular portion and a smaller annular portion concentrically integrally projecting therefrom. An outer ring and an inner ring are simultaneously produced from the workpiece by an apparatus comprising an inner ring die and an outer ring die mounted on a stationary base, and an inner ring punch and outer ring punch opposing the dies and mounted on a movable ram. The inner and outer ring punches simultaneously punch out the inner and outer rings from the workpiece fitted to the inner and outer dies. In relation to this operation, a cam operates to depress a rolling member disposed in the rear of hollow portion of the inner ring die, whereby the foremost of like finished inner rings each pushed into the hollow portion of the inner ring die at every stroke of the ram is allowed to drop through the die assembly and is thereby automatically withdrawn.

    摘要： A flexure hinge assembly wherein a pair of fixed telescoped tubular members are provided, each having one or more pairs of axially spaced slots extending through their walls, the ends of one slot of each pair terminating a predetermined circumferential distance from the corresponding ends of the other slot of the same pair to form at least two flexure portions between the ends. The flexure portions of one of the tubular members extend parallel to the axes of the members, and the flexure portions of the other tubular member extend perpendicular to the axes of the members. A method of manufacturing a flexure hinge assembly.
