Definitions

  • the present invention relates to a tool for swaging a fitting onto a tube.
  • the present invention relates to an interchangeable and secure swaging tool, as exemplified by US-A-3726122, for compressing a swage fitting onto an end of a tube.
  • Swage fittings are commonly used in aircraft, marine, petroleum and chemical industries for connecting ends of tubes together in fluid tight relationship. These swage fittings typically utilize a cylindrical shaped sleeve having an opening at opposite ends for receiving the two tube ends. Typically, a swaging tool is used to radially compress and deform the sleeve around each tube to create a fluid-tight connection between the sleeve and each tube.
  • the first type utilizes the swaging tool to deform and directly compress the sleeve against the tube
  • the second type utilizes a cylindrical collar, axially moved over the sleeve by the swaging tool to compress the sleeve to the tube.
  • the first type of swage fitting shall be referred to as a radially swaged fitting
  • the second type of swage fitting shall be referred to as an axially swaged fitting.
  • existing swaging tools utilize (i) a piston moveable in a housing from a retracted position to an extended position, (ii) a first swaging adapter affixed to the housing for holding the sleeve and (iii) a second swaging adapter affixed to the piston for inducing the radial compressive force on the sleeve when the piston is moved towards the extended position.
  • the second swaging adapter is sized and shaped to either (i) directly compress the sleeve around the tube during movement of the piston towards the extended position, or (ii) retain the collar so that the collar moves axially over the sleeve when the piston moves towards the extended position.
  • existing swaging adapters are designed to grip only a portion of the swage fitting. Since a significant amount of force may be required to axially move the collar over the sleeve to axially swage the fitting, one or both of the swaging adapters may deflect and deform, causing a swaging tool to disengage from the swage fitting and potentially cause injury to the user.
  • a swaging tool which is adaptable to a number of the different types, styles and/or sizes of swage fittings. Further, there is a need to be able to replace worn and/or damaged swaging adapters. Additionally, there is a need for a secure swaging tool that does not disengage from the swage fitting during swaging.
  • a swaging tool according to the present invention may include at least one removable swaging adapter which allows the same swaging tool to be used for different types, styles and/or sizes of swage fittings or at least one locking swaging adapter. Further, the removable swaging adapter can be replaced when worn and/or damaged.
  • a tool for swaging a fitting onto a tube the fitting having a sleeve for receiving the tube and a collar, the axial movement of the collar over the sleeve causing the collar to apply a radial force to the sleeve and swage the sleeve to the tube, the sleeve and collar each having a contact surface, the tool comprising:

  • the swage fitting 12 shown in the figures is an axially swaged fitting and the tubular sleeve 28 has opposed sleeve ends 34a, 34b which each receive an end of the tube 14 .
  • one of the opposed sleeve ends 34a, 34b can include an externally threaded or an internally threaded surface (not shown) and/or the swage fitting 12 could be a tee, an elbow or some other shaped fitting.
  • the length and shape of the swage fitting 12 varies according to the specific application, the size of the tubes 14 being connected, the required pressure rating of connection, and the preferences of the manufacturer.
  • the manufacturer determines the size and shape of the (i) sleeve 28 , (ii) the collar 32 , (iii) a contact surface 36 of the sleeve 28 , and (iv) a contact surface 38 of the collar 32 .
  • the contact surface 36 of the sleeve 28 is an annular groove in the sleeve 28 and the contact surface 38 of the collar 32 is an end of the tubular collar 32 which is annular ring shaped.

  • the forward portion 106a includes two annular grooves 112 , each annular groove 112 for receiving an O-ring 114 or other type of seal for slidingly sealing the forward portion 106a of the piston to the front cavity 46 .
