  • Patent number: 5722138
    Abstract: A disc-shaped material is prepared by punching a high carbon steel plate or soft steel plate, and the disc-shaped material is fixed in position. An outer peripheral portion of the disc-shaped material is heated to a temperature of 400.degree.-500.degree. C. by means of a high frequency heater. The outer peripheral portion of the disc-shaped material is swaged to form a thickened portion by a swaging die and the thickened portion is then spun to plastically form a toothed gear to the outer peripheral portion of the disc-shaped material in two steps of coarse working and finish working by spinning dies. The thus formed toothed gear is further heated as occasion demands to a temperature of about 900.degree. C. for quenching.

  • Patent number: 5682657
    Abstract: A pneumatic marking tool (35,123) is attached to one of the punch mounting holes (9) of the upper turret disk (3) of a punch press. When the punching striker (13) is moved down to its lower dead point, compressed air is supplied from a compressed air supply unit (103) to the marking tool to move the marking stylus (49, 129) up and down repeatedly at a high speed. At the same time, the work (W) is moved in a two-dimensional way by the Y- and X-axis work driving mechanisms (27, 29) of the punch press, in synchronism with the repetitive marking stylus motion, to engrave characters and/or symbols as a form of gathered dots all under control of the numerical control unit (33). Therefore, it is possible to mark or engrave any required characters and/or symbols without occupying a number of punch mounting stations of the upper turret disk and without the use of any punch press of high punching frequency, thus eliminating the laborious setting work required whenever the plate thickness of the work changes.

  • Patent number: 4357742
    Abstract: An apparatus for forming brush contacts from spools of wire and holders for angular ended wire segments cut from said wires, has a wire feeding means for feeding spools thereof independently of each other, a cutting device for cutting segments from the wires and feeding the segments to a common collection point where the segments are loaded into the holders provided, and a crimping device for crimping the holder to retain the wires therein without causing flaring of the exposed ends. A checking station is provided to determine whether each brush contact contains the requisite number of wire segments and ejection means to eject defective contacts. The completed contacts are collected in such a manner as to prevent damage thereto.

  • Patent number: 4197155
    Abstract: Tire building apparatus for building complete uncured tires includes a triad of orthogonally oriented tire building drums mounted on a turret rotatable about an axis inclined at an angle of between 35 and 36 degrees with respect to a horizontal plane. Each of the drums occupies successively two tire fabricating stations wherein the respective drums are oriented horizontally and a third station wherein the building drums successively occupying such third station are oriented vertically and from which completed tires fabricated in the apparatus can be removed vertically and at an elevation above the two fabricating stations so as to eliminate completely interference between the movements of tire building material coming to the machine and of the completed tires removed from the machine.

  • Patent number: RE35027
    Abstract: A turret assembly is movable in X and Y and a turret of the assembly is rotatable to position a selected one of a plurality of spindles at a transfer station of the turret. The selected spindle is telescopic to pick a component from a supply point and to place the component at a placement point on a circuit board or the like. An assembly for squaring, centering, orienting, and/or testing a component being held by another spindle of the turret is actuated generally concurrently with extending of the selected spindle. Alternatively, the spindle at the transfer station may be retained in the retracted position during actuation of the squaring assembly. Much time is saved by loading components on the plurality of the spindles of the turret at one or more supply stations and then placing all of these components without the need for transferring back and forth between the supply and P.C. board.
