Pneumatic- Or Fluid-actuated Tool Patents (Class 29/243.523)
  • Patent number: 6962068
    Abstract: A system is disclosed for installing an insert within an aperture in a workpiece, the workpiece having a first side and a second side. The insert is the type in which a portion of the insert plastically deforms on the second side of the workpiece upon application of a linear force provided by a tool, thereby preventing withdrawal of the insert from the aperture. The insert comprises a sleeve member and an integral flange, where the flange has a larger diameter than the aperture. The disclosed installation system performs two actions. It causes the expansion of the sleeve and it also causes the flange of the insert to be fused or welded to the first side of the workpiece. The welded connection between the insert and the workpiece prevents any rotation or spinning of the insert within the workpiece, and increases the integrity of the insert-fastener connection.

  • Patent number: 6418599
    Abstract: A setting apparatus 30 in which a mandrel of a blind rivet is inserted into a hole 47 of a nose at the front end of the setting apparatus, and wherein a rivet body of the rivet is projected from the nose into a mounting hole of a workpiece. The mandrel is pulled rearward of the nose with a force capable of breaking the mandrel and expanding a shank of the rivet body so that the rivet is set in the workpiece by the expanded shank and a flange of the rivet body, followed by discharging of the broken mandrel from the setting apparatus. The force for pulling the mandrel is obtained from hydraulic pressure of a hydraulic cylinder 34. The hydraulic pressure is produced by a piston 41 which moves in a pneumatic cylinder 39 adjacent to the hydraulic cylinder. The nose 31 is axially aligned with an apparatus body 33 including the hydraulic cylinder and the pneumatic cylinder 39 along the longitudinal direction of the setting apparatus 30 from the front end to the rear end thereof.

The upper and lower cartridge halves are stacked together, with a protuberance formed on the upper cartridge half being passed through the through-hole formed in the upper cartridge half, and are held by a holding mechanism. In this state, the distal end of the protuberance is thermally deformed by a caulking head, heated by a heater, and which is provided with a recess in its surface adapted to compress against the protuberance. Then, as the caulking head is moved away from the thermally deformed protuberance, the caulking head and the protuberance are cooled by a cooling mechanism.

  • Patent number: 6240613
    Abstract: A rivet setting tool is provided with a cycle control whereby a pressure switch or pressure transducer enables the electronic logic controller to monitor tool hydraulic pressure. When the pressure reaches a predetermined threshold and subsequently drops below a second threshold valve the controller deduces that a rivet has been set and removes pressure from the tool so that the tool can be immediately reset, thus reducing the tools cycle time. Upon determining that a rivet has been set, a mandrel collection window is set. The controller monitors whether a mandrel is returned to the mandrel collection system prior to the expiration of the timed window, and if not, the controller provides a fault signal to the operator. Multiple windows are utilized so that more than one mandrel can be in the return tube at one time without delaying operation of rivet setting system. The pressure sensors can also be utilized to confirm that a rivet has been loaded into the rivet setting tool without the use of a rivet sensor.
