Forward stroke pipe fitting swage machine systems and methods
Techniques for implementing and/or operating a system that includes a pipe fitting to be secured to a pipe segment, in which the pipe fitting includes a grab ring having a grab notch and a fitting jacket to be conformally deformed around tubing of the pipe segment to facilitate securing the pipe fitting to the pipe segment. Additionally, the system includes a swage machine, which includes a grab plate having a grab tab that matingly interlocks with the grab notch on the grab ring to facilitate securing the pipe fitting to the swage machine, a die plate in which a die is loaded, and a swaging actuator secured to the die plate. The swage machine operates the swaging actuator to push the die plate over the fitting jacket of the pipe fitting to facilitate conformally deforming the fitting jacket around the tubing of the pipe segment via a forward stroke.
1. A swage machine comprising:
a grab plate, wherein the grab plate comprises a grab tab configured to matingly interlock with a grab notch on a pipe fitting to facilitate securing the swage machine to the pipe fitting;
a support plate;
a die plate disposed between the grab plate and the support plate, wherein the die plate is configured to enable a set of die segments to be loaded in the swage machine such that the set of die segments opens toward the grab plate;
a support member secured to the grab plate and the support plate such that the support member enables the die plate to slide between the grab plate and the support plate; and
a swaging actuator secured to the support plate and the die plate to enable the swaging actuator to facilitate pushing the die plate over a fitting jacket of the pipe fitting in an axial direction toward the grab plate via one or more extending strokes to deform the fitting jacket of the pipe fitting around tubing of a pipe segment.
2. The swage machine of claim 1 , comprising a plurality of die actuators, wherein:
the die plate comprises a plate rim; and
each die actuator in the plurality of die actuators is secured between the plate rim of the die plate and a die segment in the set of die segments, wherein the plurality of die actuators is configured to:
retract the set of die segments toward the plate rim of the die plate to facilitate loading the pipe fitting into the swage machine, unloading the pipe fitting from the swage machine, or both; and
extend the set of die segments away from the plate rim of the die plate to facilitate engaging the set of die segments with the fitting jacket of the pipe fitting to enable the set of die segments to be used to deform the fitting jacket of the pipe fitting around the tubing of the pipe segment.
3. The swage machine of claim 2 , wherein the plurality of die actuators is configured to adjust an inner surface diameter of the set of die segments to enable the set of die segments to be used to deform fitting jackets with different diameters.
4. The swage machine of claim 1 , wherein the support member comprises a housing secured to the grab plate and the support plate such that the housing enables the die plate to slide between the grab plate and the support plate.
5. The swage machine of claim 4 , wherein the housing comprises:
a housing body; and
a housing lid pivotably connected to the housing body via a hinge, wherein the housing lid is configured to be:
opened from the housing body to facilitate loading the pipe fitting into the swage machine, unloading the pipe fitting from the swage machine, or both; and
closed onto the housing body to facilitate engaging the set of die segments loaded in the die plate with the fitting jacket of the pipe fitting to enable the set of die segments to be used to deform the fitting jacket of the pipe fitting around the tubing of the pipe segment.
6. The swage machine of claim 1 , wherein the swaging actuator is configured to facilitate pulling the die plate in an opposite axial direction away from the grab plate via one or more retracting strokes after the fitting jacket of the pipe fitting is deformed around the tubing of the pipe segment.
7. The swage machine of claim 1 , wherein the support member comprises a support rod secured to the grab plate and the support plate such that the support rod extends through the die plate to enable the die plate to slide between the grab plate and the support plate.
8. The swage machine of claim 1 , wherein the swaging actuator comprises:
an actuator cylinder secured to an inner surface of the support plate between the support plate and the die plate; and
an actuator piston secured to the die plate.
9. The swage machine of claim 1 , wherein the swaging actuator comprises:
an actuator cylinder secured to an outer surface of the support plate; and
an actuator piston that extends through the support plate and is secured to the die plate.
10. The swage machine of claim 1 , wherein the die plate is configured to enable four or more die segments to be concurrently loaded in the swage machine.
11. The swage machine of claim 1 , comprising:
another support plate;
another die plate disposed between the grab plate and the another support plate, wherein:
the another die plate is configured to enable another set of die segments to be loaded in the swage machine such that another set of die segments open toward the grab plate; and
the support member is secured to the grab plate and the another support plate such that the support member enables the another die plate to slide between the grab plate and the another support plate; and
another swaging actuator secured to the die plate and the another support plate to enable the another swaging actuator to facilitate pushing the another die plate over another fitting jacket of the pipe fitting in an opposite axial direction toward the grab plate via one or more extending strokes to deform the another fitting jacket of the pipe fitting around other tubing of another pipe segment.
