Abstract

A pipe-cutting device comprising a portable support; a device for rotating said pipe relative the support; a cutter associated with said support for cutting the pipe during rotation of the pipe.

Claims (30)

1. A pipe-cutting device comprising:

(a) a portable support;

(b) means for rotating said pipe relative said support;

(c) a cutter associated with said support for cutting said pipe during rotation of said pipe;

(d) means for bevelling a cut end of said pipe;

(e) collar means for clamping said pipe, wherein said collar means comprises:

(i) first and second collars each adapted to receive said pipe;

(ii) said second collar rotatably displaceable relative said first collar so as to capture said pipe within said first and second collar.

2. A pipe-cutting device as claimed in claim 1 wherein said rotating means comprises at least one drive wheel rotatably engageable with said collar means for rotating said pipe.

3. A pipe-cutting device as claimed in claim 2 , including a frame disposed above said support.

4. A pipe-cutting device as claimed in claim 3 , wherein said frame includes displaceable pressure means for pressuring said collar means against said at least one drive wheel for rotating said pipe.

5. A pipe-cutting device as claimed in claim 4 , wherein said bevelling means includes a router selectably displaceable relative said support for bevelling the cut end of said pipe.

6. A pipe-cutting device comprising:

(a) a substantially horizontal table for supporting said pipe;

(b) a saw disposed above said table for cutting said pipe;

(c) a frame connected to and disposed above said table, said frame including pressure wheels;

(d) drive means disposed below said table;

(e) means for circumferentially clamping said pipe, said clamping means:

(i) disposed between said pressure wheels and said drive means;

(ii) adapted to be rotatably driven by said drive means so as to cut said pipe with said saw during rotation of said pipe.

7. A pipe-cutting device as claimed in claim 6 , wherein said frame includes means for moving said pressure wheels relative said circumferential clamping means so as to move said clamping means in engagement with said drive means.

8. A pipe-cutting device as claimed in claim 7 , wherein said drive means includes a knurled drive wheel.

9. A pipe-cutting device as claimed in claim 8 , wherein said clamping means includes:

(a) a first collar for receiving said pipe;

(b) a second collar for receiving said pipe, said second collar adapted for threadable engagement with said first collar, and said second collar includes tapered fingers for clamping said pipe.

10. A pipe-cutting device as claimed in claim 9 , wherein said frame includes scissor means carrying said pressure wheels.

11. A pipe-cutting device as claimed in claim 10 , wherein said drive means comprise a variable speed motor.

12. A pipe-cutting device as claimed in claim 11 , wherein said drive means includes a generator permitting movement of said device into the field.

13. A pipe-cutting device as claimed in claim 12 , including a router disposed below said table for bevelling the end of a cut end of said pipe.

14. A pipe-cutting device as claimed in claim 13 , wherein said router is moveable relative said table.
