Abstract
A mobile device for simultaneously cutting and chamfering a pipe is provided having a frame, at least one pipe collet-clamp attached to the frame and defining a principal axis, a split carriage rotatably mounted with respect to the frame about the axis and adjacent to the clamp(s), a router affixed to the split carriage and having a cutting-chambering bit, and a drive motor for rotating the carriage. The router orbits around the pipe and simultaneously cuts it into two chamfered pipes. A method is also provided for cutting through a pipe and chambering the cut ends thereof.
Claims10
A mobile device for simultaneously cutting and chamfering a pipe, the improvement comprising:
- a mobile frame;
- a pair of pipe collet-clamps attached to the frame and defining a principal axis;
- a split carriage rotatably mounted with respect to the frame about the axis and between the clamps;
- a router affixed to the split carriage and having a cutting-chamfering bit;
- and
- a drive motor for rotating the carriage;
- whereby the router orbits around the pipe simultaneously cutting it into two chamfered pipes.
A device for simultaneously cutting and chamfering a pipe, the improvement comprising:
- a mobile frame;
- a pair of pipe supports attached to the frame and defining with the pipe a principal axis;
- a split carriage mounted with respect to the frame relatively rotatable with respect to the supported pipe about the axis and, in the axial direction, between the pipe supports;
- a router affixed to the split carriage and having a cutting-chamfering bit;
- and
- a drive motor for motivating relative orbital rotation of the carriage around the pipe;
- whereby the pipe is simultaneously cut into two chamfered pipes.
