    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: 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.

    摘要: In a step of forming a roller bearing cage (13) including a first roller stopper part (16a) provided on the radial inner side to prevent a roller from escaping to the radial inner side, and a second roller stopper part (17a) provided on the radial outer side to prevent the roller from escaping to the radial outer side, on wall surfaces (16b) and (17b) opposed to a pocket (20), respectively, each of the first and second roller stopper parts (16a) and (17a) is formed by a process only from the one radial side with a jig (60).
