Abstract
A device and associated system for threading, cutting, and reaming pipe ends are described. The device and system utilizes a brushless DC electric motor. The devices also include on-board electronics and operator interface(s) to provide sophisticated control and information as to the various operations. Also described are methods of operating the devices and several different modes for performing various operations.
Claims12
A powered threader device comprising:
- a frame assembly;
- a selectively releasable chuck assembly adapted for retaining and rotating a workpiece about a workpiece central axis;
- a brushless DC electric motor supported by the frame assembly, the motor providing a powered rotary output in selectable engagement with the chuck assembly to thereby selectively rotate the workpiece;
- a selectively positionable die assembly for forming threads in the workpiece, the die assembly including a receding die head.
