Abstract

A pipe cutting tool having: a plurality of rollers; a clamping member moveable between an open position in which a pipe is insertable between the plurality of rollers and a clamping position in which the pipe is secured between the rollers; a cutting apparatus having first, second, and third cutting members configured to optionally sequentially engage the pipe when positioned between the plurality of rollers; a drive motor drivingly connected to at least one of the rollers; and an actuator operatively connected to the drive motor.

Claims

1. A cutting tool for a pipe comprising:

(a) a plurality of rollers comprising a first set of lower rollers configured to support a pipe having a first diameter, a second set of lower rollers configured to support a pipe having a second diameter that is larger than the first diameter and at least one upper roller;

(b) a clamping member moveable between an open position in which the pipe is insertable between the plurality of rollers and a clamping position in which the pipe is secured between the rollers;

(c) a cutting apparatus comprising a plurality of cutting members configured to sequentially engage the pipe when positioned between the plurality of rollers;

(d) a drive motor drivingly connected to at least one of the rollers;

(e) an actuator operatively connected to the drive motor; and

,

(f) a support trough having the first set of lower rollers and the second set of lower rollers.

2. The cutting tool of claim 1 wherein the clamping member comprises the at least one upper roller.

3. The cutting tool of claim 1 wherein the plurality of cutting members comprises a first cutting member that is configured to cut an annular groove in the pipe, a second cutting member that is configured to chamfer at least a portion of the pipe located between the first and third cutting members, and a third cutting member that is configured to cut the pipe into two sections at a location on one side of the groove.

4. The cutting tool of claim 1 wherein the support trough is generally V-shaped with the first set of lower rollers is positioned in a lower portion of the trough and the second set of lower rollers is positioned above the first set of lower rollers.

5. The cutting tool of claim 1 wherein the drive motor is drivingly connected to the at least one set of lower rollers.

6. The cutting tool of claim 1 wherein the clamping member comprises the at least one upper roller and the cutting apparatus.

7. A cutting tool comprising

(a) a plurality of rollers;

(b) a clamping member moveable between an open position in which the pipe is insertable between the plurality of rollers and a clamping position in which the pipe is secured between the rollers;

(c) a cutting apparatus comprising a plurality of cutting members configured to sequentially engage the pipe when positioned between the plurality of rollers;

(d) a drive motor drivingly connected to at least one of the rollers; and

,

(e) an actuator operatively connected to the drive motor,

wherein the clamping member comprises at least one upper roller and the cutting apparatus, and

wherein the at least one upper roller comprises first and second spaced apart upper rollers and the cutting apparatus is positioned between the first and second spaced apart upper rollers.

8. The cutting tool of claim 7 wherein the at least one set of lower rollers comprises a first set of lower rollers configured to support a pipe having a first diameter and a second set of lower rollers configured to support a pipe having a second diameter that is larger than the first diameter.

9. The cutting tool of claim 7 wherein the cutting apparatus is non-rotationally mounted on a shaft, and the first and second spaced apart upper rollers are rotationally mounted on the shaft.

10. The cutting tool of claim 9 further comprising a cutting lever drivingly connected to the shaft, the cutting lever is moveable between a first position in which the first cutting member engages the pipe, a second position in which the second cutting member engages the pipe and a third position in which the third cutting member engages the pipe.

11. The cutting tool of claim 10 wherein the cutting lever is moveable from a neutral position in which the cutting apparatus does not engage the pipe and the first position.

12. The cutting tool of claim 7 wherein the plurality of cutting members comprises a first cutting member that is configured to cut an annular groove in the pipe, a second cutting member that is configured to chamfer at least a portion of the pipe located between the first and third cutting members, and a third cutting member that is configured to cut the pipe into two sections at a location on one side of the groove.

13. A cutting tool comprising

(a) a plurality of rollers comprising a first set of lower rollers, a second set of lower rollers and at least one upper roller;

(b) a clamping member moveable between an open position in which the pipe is insertable between the plurality of rollers and a clamping position in which the pipe is secured between the rollers;

(c) a cutting apparatus comprising a plurality of cutting members configured to sequentially engage the pipe when positioned between the plurality of rollers;

(d) a drive motor drivingly connected to at least one of the rollers;

(e) an actuator operatively connected to the drive motor, and,

(f) a support trough having the first set of lower rollers and the second set of lower rollers,

wherein the plurality of rollers, the clamping member and the cutting apparatus are provided in a main body and the support trough extends to either side of the main body.

14. The cutting tool of claim 13 wherein the support trough includes an adjustable pipe stop.

15. The cutting tool of claim 13 wherein the plurality of cutting members comprises a first cutting member that is configured to cut an annular groove in the pipe, a second cutting member that is configured to chamfer at least a portion of the pipe located between the first and third cutting members, and a third cutting member that is configured to cut the pipe into two sections at a location on one side of the groove.
