Title: Pipe cutter for propulsion
Inventor: KIMURA KOICHI
IPC: B23D21/08
Filed: 1993-01-29
Abstract: PURPOSE:To cut and machine a buried pipe for propulsion accurately in a short time by arranging machining edges having a diameter smaller than a discoid cutting edge on both sides of the cutting edge disposed at a center. CONSTITUTION:A discoid cutting edge 2 arranged at the center of a cutter 1 and machining edges 3, 3 disposed on both sides of the cutting edge 2 are rotated by operating a driver 8. The size of the machining edge 3 is formed in size smaller than the outside diameter of the cutting edge 2 so that the thickness section of the interior shell of a buried pipe is left. Consequently, the cutting edge 2 having a large diameter at the center is brought into contact with the exterior shell of the buried pipe first and starts the cutting of a wall surface, and the machining edges 3 on both sides begin to machine the wall surface of the buried pipe as cutting progresses. When the cutting and machining of the buried pipe are completed, guide rings 4 on both sides of the machining edges 3 are abutted against the exterior shell of the buried pipe, thus preventing the machining of the interior shell by the machining edges 3.
