Swaging Patents (Class 76/51)
  • Patent number: 7861617
    Abstract: A hand-operated swage device includes a first hand-operated actuator and a second hand operated actuator that, when actuated together, control the sequential operation of a clamping mechanism and a swaging mechanism of the hand-operated swage device. For example, the first actuator of the swage device is disposed on a first handle while the second actuator is disposed on a second handle of the swage device. To operate the hand-operated swage device, an operator grasps the first handle with one hand and grasps the second handle with his other hand to actuate both of the actuators in a substantially simultaneous manner. Actuation of both actuators controls sequential delivery of pressurized air to a first pneumatic device mechanically coupled to the clamping mechanism and to a second pneumatic device mechanically coupled to the swaging mechanism.

  • Patent number: 7854183
    Abstract: A swage anvil includes a coupling portion that, when mated with a corresponding die of a swaging device, allows lateral positioning of the swage anvil (i.e., substantially parallel to a long axis of the saw blade) relative to the long axis of the saw blade. The swage anvil also includes a tooth contact face that substantially mirrors an angle of the back portion of each tooth of the saw blade. As such, after a manufacturer inserts the swage anvil into the swage device and laterally translates the swage anvil, the tooth contact face abuts the back portion of the saw blade tooth to support the tooth during a swaging procedure. With the aforementioned configuration of the swage anvil, translation of the swage anvil along a single axis provides support to the back portion of the saw blade tooth along two axes. As such, use of the swage anvil decreases the set-up time required in conventional swaging devices.

  • Patent number: 5904939
    Abstract: An apparatus for manufacturing a rod of hard metal or ceramic with at least one helical inner bore. A plasticized mass of hard metal or ceramic is simultaneously forced through a die and twisted. Either the mass is twisted uniformly over the cross-section of the billet by a spinner immersed in the mass or the spinner is rotated by the mass. The mass emerges either subject to torsion or entirely or mostly without torsion from a smooth downstream channel through the die. A filament-shaped material extends or is injected into the mass to produce the inner bore or bores.

  • Patent number: 5601857
    Abstract: An extruder for extrusion manufacturing one of a hard metal and a ceramic rod with at least one helical inner bore and having a smooth outer surface substantially free of elevations and depressions includes a housing and a die connected to the housing. The mechanism for forcing a plasticized mass through the die is provided wherein the mass is shaped in the form of a billet having a cross-section. A spinner is located in the housing upstream of the die for twisting the mass uniformly over the cross-section of the billet, the spinner being surrounded by an axial flow of the mass. A smooth channel is located downstream of the spinner such that the mass emerges from the channel through the die and a mechanism is provided suspending a filament in the mass wherein the filament follows a twisting movement of the twisted mass so as to form a helical inner bore therein.

  • Patent number: 5367836
    Abstract: An automatic drill loader is used with a drill grinding machine to automatically present drills to the drill grinding machine workhead for being ground thereat and to carry ground drills to a storage receptacle. The automatic drill loader comprises a magazine, a timing station, and two sets of grippers. The magazine stores a quantity of drills, which may have stepped shanks. The magazine is adjustable to suit drills of different lengths and diameters. The magazine presents one drill at a time to a staging station. A load gripper grips the drill at the staging station and conveys it to the timing station, whereat the drill is linearly and angularly oriented. The load gripper then transports the drill to the drill grinding machine workhead. Simultaneously, an unload gripper carries a ground drill from the drill grinding machine workhead to the storage receptacle.

  • Patent number: 5263286
    Abstract: A drill having a pair of cutting edges formed at one end of a shank and arranged symmetrically with respect to a point, each cutting edge comprising a central edge portion and an outer edge portion, the central and outer edge portions each extending substantially straight and being joined to each other with an obtuse angle formed therebetween when seen from below, the central edge portion being formed with a cutting face substantially parallel to the axis of the drill, the land portion of the two edge portions having a top face joined to the cutting face of the central edge portion and curved in a direction to give a large area to the cutting face; a method of grinding the drill with the outer periphery and a side surface of a rotary grinder; and a drill grinding apparatus for practicing the method comprising a holding frame for reciprocatingly moving the drill axially thereof, means for rotating the drill, a disklike rotary grinder, and posture changing means for altering the angle between the grinding porti

  • Patent number: 5201795
    Abstract: Method and apparatus for forming a base defining a trunnion and a portion of a leg for a roller-cone-type rock bit. A workpiece is rough formed to comprise leg work, having a preliminary end surface, and trunnion work extending angularly from the leg work. An interface plate is mounted on a holder of a lathe with an indexing surface thereof facing generally radially inwardly but angled to correspond to a desired angular orientation of a trunnion in a finished bit. The workpiece is removably mounted on the interface plate, with the preliminary end surface abutting the indexing surface, by at least one pin-type connector projecting from one of the surfaces into the other. The trunnion work is then turned on the lathe. Other parts of the machining of the workpiece may be performed by removing the workpiece from the first interface plate and similarly mounting it on plates adapted for other machines, but otherwise similar to the first plate.
