Abstract
A tool for removing material or machining the end of a pipe. The tool having at least one and preferably two blade plates. Each blade plate includes a first cutter for machining an end surface of the pipe, a second cutter adjacent the first cutter for producing an internal chamfer in the pipe end and a third cutter adjacent the first cutter positioned for producing an external chamfer adjoining the end surface of the pipe end. Devices guide and permit movement of the cutters either radially or axially. The shaping of the cutter is disclosed.
Claims10
A tool for machining a pipe end by relative rotation of the tool and the pipe end, the tool, comprising:
- two blade plates fixed on the tool;
- a first cutter on each of the blade plates and shaped and positioned for producing or machining a flat end surface of the pipe end;
- a second cutter on each of the blade plates and shaped and positioned for producing or machining an internal chamfer in the pipe end adjoining the end surface;
- a third cutter on each of the blade plates for producing or machining an external chamfer on the pipe end adjoining the end surface, the tool having a rotation axis;
- a radial setting device for setting the radial position of the blade plates;
- and
- an axial setting device for setting the axial position of the blade plates with respect to the pipe end, first and second blade plates being arranged on the tool so as to not lie diametrically opposite one another around the tool axis wherein the radial setting device is adjusted separately from the axial setting device.
