Field portable pipe-mounted pipe cutting system with integral controls
A field portable pipe-mounted pipe cutting system with integral controls. The system includes a torch carriage assembly having a torch for cutting a cylindrical pipe. A saddle and cap ring assembly is secured to the pipe. A ring gear engages the saddle and cap ring. At least one drive gear engages the ring gear. A drive gear step motor rotates the drive gear. A motion control module controls movement of the step drive motor. The lead screw assembly moves the torch carriage assembly longitudinally parallel to an axis of the pipe. A lead screw step drive motor drives the lead screw assembly and a motion control module controls movement of the lead screw step drive motor.
1. A field portable pipe-mounted pipe cutting system with integral controls, which system comprises:
a torch carriage assembly having a torch for cutting a cylindrical pipe;
a saddle and cap ring assembly secured to said pipe;
a ring gear engaging said saddle and cap ring;
at least one drive gear engaging said ring gear;
a drive gear step drive motor having a shaft rotating said drive gear;
a motion control module to control movement of said drive gear step drive motor and said at least one drive gear;
a lead screw assembly moving said torch carriage assembly longitudinally parallel to an axis of said pipe;
a lead screw step drive motor driving said lead screw assembly; and
a motion control module to control movement of said lead screw step drive motor and said lead screw assembly.
2. The pipe cutting system as set forth in claim 1 including interface software to interface with a central processing unit having software to control said motion control module.
3. The pipe cutting system as set forth in claim 1 wherein said motion control module, step drivers and a power supply are contained in a housing attached to said saddle and cap ring.
4. The pipe cutting system as set forth in claim 1 wherein said torch carriage assembly includes a torch holder retaining said torch and wherein said torch holder is adjustable for selected orientation.
5. The pipe cutting system as set forth in claim 1 including computer program software and a database to select from a plurality of cuts configuration options and to implement a selected cut by interface with said drive gear step drive motor motion control module and said lead screw step drive motion control module.
6. The pipe cutting system as set forth in claim 1 wherein said at least one drive gear includes a pair of drive gears connected by a chain.
7. A pipe cutting process for a field portable pipe-mounted pipe cutting system, which process comprises:
mounting a field portable pipe cutting system with integral controls on a cylindrical pipe;
connecting said pipe cutting system to a computer software program to select and control at least one step motion control module, which controls a drive gear step drive motor;
connecting said pipe cutting system to a computer software program to select and control at least one lead screw motion control module to control movement of a lead screw step drive motor;
selecting whether to create a new pipe cut or a previous cut;
if a new cut, selecting from a plurality of different cut configuration options; and
implementing the selected cut in accordance with a selected cut configuration option chosen from the plurality of different cut configuration options.
8. A process as set forth in claim 7 wherein the plurality of different cut configuration options includes:
a straight cut, a miter cut, a saddle hole cut, a saddle cut, a square/round cut, and a library of custom cuts configurations created individually as requested.
