Claims

[Scope of Claim for Utility Model Registration] An inner cutter having a plurality of convex cutting edges protruding from the outer periphery of a disc-shaped body at intervals, and an inner cutter rotatably held within a pipe to be processed; a support loft that holds the axis of the inner cutter so that it intersects with the diameter direction of the pipe to be processed; a reaction force receiver that supports the inner cutter so that the convex cutting edge of the inner cutter contacts the inner surface of the pipe to be processed; a drive device that moves the processing tube relative to the inner cutter in the axial direction; When the shaped cutting blade protrudes outward from the pipe to be processed, a receiving blade that pinches both sides of the convex cutting blade in the circumferential direction of the pipe to be processed, and a receiving blade that is disposed outside the pipe to be processed and that holds the pipe to be processed by its diameter. The convex cutting edge and the receiving blade work together to form a line of shearing action on both sides of the convex cutting blade in the circumferential direction of the workpiece pipe, and Both sides of the pipe are characterized in that the portion of the pipe sandwiched by the line of shear action is raised outward. Side hole band-shaped protrusion processing device.
