Abstract
A swage tool for swaging axially swaged fittings includes a housing having an inner surface and a first yoke. A ram includes a recessed portion having a threaded inner surface portion. A piston includes a second yoke. A piston rod includes a spring holder and a threaded portion screwed into the threaded inner surface portion of the ram. A spring is connected to the spring holder. Carbon fiber bearings are provided on the ram and on an outer surface portion of the piston rod in axial slidable engagement with the inner surface of the housing.
Claims21
A swage tool for swaging axially swaged fittings comprising:
- a housing having an inner surface and a first yoke;
- a ram having a recessed portion with a threaded inner surface portion;
- a piston having a second yoke;
- a piston rod having a spring holder and a threaded portion screwed into the threaded inner surface portion of the ram;
- a spring connected to the spring holder;
- and
- carbon fiber bearings provided on the ram and on an outermost surface portion of the piston rod at a widest diameter in axial slidable engagement with the inner surface of the housing such that the ram and the outermost surface portion of the piston rod do not directly slidably engage with the inner surface of the housing.
A swaging system for joining a first member to a second member comprising:
- a fitting including a sleeve inserted over the first and second members;
- a first ring provided over the sleeve to axially swage the sleeve to the first member;
- a second ring provided over the sleeve to axially swage the sleeve to the second member;
- a swage tool comprising:
- a housing having an inner surface and a first yoke;
- a ram having a recessed portion with a threaded inner surface portion;
- a piston having a second yoke;
- a piston rod having a spring holder and a threaded portion screwed into the threaded inner surface portion of the ram;
- a spring connected to the spring holder;
- and
- carbon fiber bearings provided on the ram and on an outermost surface portion of the piston rod at a widest diameter in axial slidable engagement with the inner surface of the housing such that the ram and the outermost surface portion of the piston rod do not directly slidably engage with the inner surface of the housing,
- wherein the first and second yokes engage the sleeve and either the first or second ring.
A method of assembling a swage tool comprising:
- a) attaching a carbon fiber bearing over a ram and an outermost surface of a piston rod at a widest diameter;
- b) inserting the ram within a housing;
- c) inserting a piston adjacent to the ram within the housing;
- d) inserting the piston rod through the piston;
- and
- e) screwing a threaded portion of the piston rod into a threaded inner surface portion of the ram, wherein the ram and the outermost surface portion of the piston rod do not directly slidably engage with an inner surface of the housing.
