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.
Claims8
An apparatus for cutting pipe, the apparatus comprising:
- (a) a base comprising a pipe support having at least one set of lower rollers;
- (b) an upper frame supporting a first cutting apparatus, a second cutting apparatus, and at least one upper roller, the upper frame being moveable relative to the base between an open position in which a pipe may be inserted between the at least one set of lower rollers and the at least one upper roller, and a clamping position in which the inserted pipe is in contact with the at least one set of lower rollers and the at least one upper roller;
- (c) the first and second cutting apparatus being moveable between a first cutting position in which the first cutting apparatus is positioned to cut a pipe having a first diameter, and a second cutting position in which the second cutting apparatus is positioned to cut a pipe having a second diameter that is smaller than the first diameter;
- (d) a drive motor drivingly connected to at least one roller in the at least one set of lower rollers;
- and,
- (e) an actuator operatively connected to the drive motor
- wherein the first cutting apparatus comprises a first grooving member configured to provide an annular groove on an outer surface of a pipe having the first diameter, a first cutting member configured to cut the pipe of the first diameter into first and second sections, and a first chamfering member configured to provide a chamfer on the outer surface of the pipe of the first diameter between a location of the annular groove and a location of the cut in the pipe, and
- wherein the second cutting apparatus comprises a second grooving member configured to provide an annular groove on an outer surface of a pipe having the second diameter, a second cutting member configured to cut the pipe of the second diameter into first and second sections, and a second chamfering member configured to provide a chamfer on the outer surface of the pipe of the second diameter between a location of the annular groove and a location of the cut in the pipe.
