Abstract

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. The system includes a swage machine, which includes a grab plate having a grab tab that matingly interlocks with the grab notch to facilitate securing the pipe fitting to the swage machine, a die plate including a die that opens away from the grab plate, and a swaging actuator secured to the die plate. The swage machine operates the swaging actuator to move the die plate over the fitting jacket in an outwardly axial direction away from the grab plate to facilitate conformally deforming the fitting jacket around the tubing of the pipe segment.

First claim

What is claimed is:

1. A swage machine comprising:
a grab plate configured to interlock with a 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;
a support rod secured to the grab plate and the support plate such that the support rod extends through the die plate; and
a swaging actuator, wherein the swaging actuator comprises:
an actuator cylinder secured to the support plate; and
an actuator piston secured to the die plate.

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 corresponding die segment in the set of die segments.

3. The swage machine of claim 2 , wherein each die actuator in the plurality of die actuators comprises:
another actuator cylinder secured to the plate rim of the die plate; and
another actuator piston secured to the corresponding die segment in the set of die segments.

4. The swage machine of claim 1 , comprising another swaging actuator, wherein the another swaging actuator comprises:
another actuator cylinder secured to the support plate; and
another actuator piston secured to the die plate.

5. The swage machine of claim 1 , wherein the actuator cylinder of the swaging actuator is secured to an inner surface of the support plate between the support plate and the die plate.

6. The swage machine of claim 1 , wherein:
the actuator cylinder of the swaging actuator is secured to an outer surface of the support plate; and
the actuator piston of the swaging actuator extends through the support plate.

7. The swage machine of claim 1 , wherein the die plate is configured to enable the set of die segments to be loaded in the swage machine such that the set of die segments opens toward the grab plate.

8. The swage machine of claim 1 , wherein the die plate is configured to enable the set of die segments to be loaded in the swage machine such that the set of die segments opens away from the grab plate.

9. A method of implementing a swage machine, comprising:
implementing a grab plate to enable the grab plate to interlock with a pipe fitting;
implementing a support plate;
implementing a die plate to enable a set of die segments to be loaded in the swage machine;
disposing the die plate between the grab plate and the support plate;
securing a support rod to the grab plate and the support plate such that the support rod extends through the die plate; and
securing a swaging actuator to the grab plate and the die plate.

10. The method of claim 9 , wherein securing the swaging actuator to the grab plate and the die plate comprises:
securing an actuator cylinder of the swaging actuator to the support plate; and
securing an actuator piston of the swaging actuator to the die plate.

11. The method of claim 10 , wherein securing the actuator cylinder of the swaging actuator to the support plate comprises securing the actuator cylinder to an inner surface of the support plate between the support plate and the die plate.

12. The method of claim 10 , wherein:
securing the actuator cylinder of the swaging actuator to the support plate comprises securing the actuator cylinder to an outer surface of the support plate; and
securing the actuator piston of the swaging actuator to the die plate comprises securing the actuator piston to the die plate such that the actuator piston extends through the grab plate.

13. The method of claim 9 , wherein disposing the die plate between the grab plate and the support plate comprises disposing the die plate between the grab plate and the support plate such that the die plate enables the set of die segments to be loaded in the swage machine such that the set of die segments opens toward the grab plate.

14. The method of claim 9 , wherein disposing the die plate between the grab plate and the support plate comprises disposing the die plate between the grab plate and the support plate such that the die plate enables the set of die segments to be loaded in the swage machine such that the set of die segments opens away from the grab plate.

15. The method of claim 9 , wherein implementing the die plate comprises:
forming a plate rim; and
securing each of a plurality of die actuators between the plate rim and a corresponding die segment in the set of die segments.

16. A swage machine comprising:
a grab plate configured to interlock with a pipe fitting;
a die plate configured to enable a set of die segments to be loaded in the swage machine, wherein the die plate comprises:
a plate rim; and
a plurality of die actuators, wherein each die actuator in the plurality of die actuators is secured between the plate rim and a corresponding die segment in the set of die segments; and

a plurality of swaging actuators secured to the die plate.

17. The swage machine of claim 16 , comprising a support plate, wherein:
the die plate is disposed between the grab plate and the support plate; and
the plurality of swaging actuators is secured to the support plate.

18. The swage machine of claim 17 , wherein each of the plurality of swaging actuators 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.

19. The swage machine of claim 17 , wherein each of the plurality of swaging actuators comprises:
an actuator cylinder secured to an outer surface of the support plate; and
an actuator piston secured to the die plate such that the actuator piston extends through the support plate.

20. The swage machine of claim 16 , wherein each of the plurality of die actuators comprises:
an actuator cylinder secured to the plate rim of the die plate; and
an actuator piston secured to the corresponding die segment in the set of die segments.
