ABSTRACT:
A secure swaging tool 10 for compressing an axially swaged fitting 12 having a sleeve 28 and a collar 32 onto a tube 14 includes (i) a housing 16 defining a partially enclosed chamber 40; (ii) a movable element 18, i.e., a piston, disposed within the chamber 40 and movable between a retracted position 102 and an extended position 104; (iii) a housing jaw 20 attached to the housing 16; (iv) a movable jaw 22 affixed to the movable element 18, movement of the movable element 18 from the retracted position 102 to the extended position 104 causes the movable jaw 22 to approach the housing jaw 20 along a fixed axis; and (v) first and second swaging adapters 24, 26, one swaging adapter is disposed in each jaw. The first swaging adapter 24 retains the sleeve 28 while the second swaging adapter 26 retains the collar 32 which induces a radial swaging force to the sleeve 28 when the movable element 18 is moved from the retracted position 102 towards the extended position 104. At least one of the swaging adapters 24, 26 is a locking swaging adapter which substantially encircles a portion of the axially swaged fitting so that the swaging tool 10 does not disengage from the swage fitting 12 during swaging. Further, at least one of the swaging adapters 24, 26 can be removably attached to one of the jaws 20, 22 so that a different swaging adapter can be used for different types, styles or sizes of swage fittings. Optimumly, the housing jaw and the movable jaw 22 each alternately and removably accept and restrain both swaging adapters 24, 26 so that both swaging adapters 24, 26 can be disposed in either jaw so that the orientation of the swaging tool 10 can be rotated to be used in confined areas.
