Abstract
A swage mechanism operable to expand an inner diameter of tubing. The swage mechanism includes a housing defining a longitudinal axis, a plurality of jaws coupled to the housing and movable relative to the longitudinal axis for selectively gripping the tubing, and a ram including a cylindrical portion and a frusto-conical head portion. The frusto-conical head portion of the ram is insertable into the tubing to expand the inner diameter of the tubing.

A swage mechanism operable to expand an inner diameter of tubing, the swage mechanism comprising:
- a housing defining a longitudinal axis;
- a plurality of jaws coupled to the housing and movable relative to the longitudinal axis for selectively gripping the tubing, wherein the jaws each include a first cam surface;
- a ram including a cylindrical portion and a frusto-conical head portion, wherein the frusto-conical head portion of the ram is insertable into the tubing to expand the inner diameter of the tubing;
- and
- a body coupled to the housing and having a second cam surface;
- wherein the second cam surface of the body is engageable with the first cam surface of each of the jaws to move the jaws toward or away from the longitudinal axis, wherein the jaws are moved when the second cam surface is moved in a direction along the longitudinal axis and the jaws are moved when the second cam surface is rotated around the longitudinal axis.
A swage mechanism operable to expand an inner diameter of tubing, the swage mechanism comprising:
- a housing defining a longitudinal axis;
- a plurality of jaws coupled to the housing and movable inward relative to the longitudinal axis for selectively gripping an exterior of the tubing, each of the jaws having a first cam surface formed on an exterior thereof;
- a sleeve disposed within the housing and having a second cam surface in slidable contact with the first cam surfaces of the respective jaws for moving the jaws toward or away from the longitudinal axis in response to movement of the sleeve along the longitudinal axis;
- and
- a ram movable along the longitudinal axis and having a cylindrical portion and a frusto-conical head portion, wherein the frusto-conical head portion of the ram is insertable into the tubing to expand the inner diameter of the tubing,
- wherein the sleeve includes a plurality of grooves, each of which receives a corresponding radially inward-extending pin on the housing to rotatably and slidably interconnect the sleeve to the housing.
