摘要： PROBLEM TO BE SOLVED: To easily cut a down pipe and form a beautiful cut section by connecting a right semicylinder for surrounding the right half of the down pipe to the left semicylinder for surrounding the left half of the down pipe in such a state as opening/closing freely. SOLUTION: A right semicylinder 3 and a left semicylinder 4 are opened and the left semicylinder 4 is closely applied to the external face of a down pipe 1. Secondly, an opening/closing hook 7 is rotationally moved so that its engaging ring 8 is hooked on a hook 9 and, when the opening/closing hook 7 is fastened, a cutter 11 of the right semicylinder 3 bites into the down pipe 1. Then, if the down pipe 1 is rotated in the direction shown by an arrow with it held with the both hands, the down pipe 1 is easily cut by the action of the acute cutter 11. Meanwhile, the right semicylinder 3 and the left semicylinder 4 are closely stuck to the down pipe 1 to be prevented from vertically deviated so that the cutting start and the cutting end are coincided with each other to form a beautiful cut section.

摘要： PURPOSE:To provide a cutting device for a pipe which can simply out the cutting work and is favorable in workability even if there is not so large space around the pipe or it is a large diameter pipe. CONSTITUTION:A ring frame 2 capable of being fitted outside a pipe 1 is divided into two parts in the diametral direction so as to be able to outside fit to the pipe from the diametral direction, loosely rolling rollers 4 allowing the ring frame 2 to rotate around the pipe 1 are provided, a cutter 5 rotating around the pipe 1 together with the ring frame 2 and cutting the pipe 1 along the circumferential direction is provided, the ring frame 2 is rotatably supported with a casing main body 3, and a rotational drive part for driving to rotate the ring frame 2 is provided on the casing main body 3. A feed mechanism operation part 11 operating a cutter feed mechanism 8 at every time when the cutter feed mechanism 8 reaches a prescribed position accompanying rotation of the ring frame 2 is provided on the casing main body 3 so that it interferes with the cutter feed mechanism 8 and projectingly feeds the cutter 5 toward the pipe 1.

摘要： PURPOSE:To provide a pipe cutting tool capable of sectionally cutting a pipe easily with extremely small force while being compact, portable, low-priced and easily usable in a narrow place. CONSTITUTION:A recessed part 3 allowing a pipe 2 to be inserted rotatably without looseness from an inlet-outlet 1 is formed at base material 4, and a cutting tool 5 for biting and sectionally cutting the pipe 2 inserted into the recessed part 3 is fitted to the base material 4 in such a way as to protrude into the recessed part 3. The tool tip 6 of the cutting tool 5 is gradually tapered, and the cutting tool 5 is fitted into a position out of the width direction centerline Y-Y of the recessed part 3. The cutting edge 7 of the cutting tool 5 is fitted in such a way as to face the back wall 8 of the recessed part, and the tool tip 6 of the cutting tool 5 is fitted into such a position as to collide with the pipe 2 before the pipe 2 collides with the back wall 8. The protruding length of the cutting tool 5 is set into such length as to be able to pierce only the wall of the pipe 2 inserted into the recessed part 3, and the peripheral wall surface 9 of the recessed part 3 is protrusively provided with guide rails 11 to be fitted into the hollows of the corrugated pipe.

摘要： PURPOSE:To carry out pipe cutting smoothly by arranging a push-pressing force receiving member in the tip part of a cylindrical body so that push-pressing force can be received from outside of a pipe when a cutter is cut into the pipe. CONSTITUTION:A shaft shape body 7 is inserted into a cylindrical body 6, which is provided with a cutter 5 to cut into a pipe from inside, on the tip side so as to be operated freely, and a pipe inside surface receiving member 10 situating on the opposite side of the diameter direction is also arranged in the cylindrical body 6. The clearance between the cutter 5 and the pipe inside surface receiving member 10 is constituted so as to be expanded/contracted freely according to operation of the shaft shape body 7, and a push-pressing force receiving member 11, which receives push-pressing force from inside of the pipe when the cutter 5 is cut into the pipe by expanding the clearance, is arranged in the tip part of the cylindrical body 6. Thereby, since the push-pressing force applied by the cutter 5 can be received in the cutting place of the pipe by means of the push-pressing force receiving member 11, by operation in which a cut/removed part of the pipe is moved outward to expand its diameter, the tip part of the pipe can be prevented from being bent, so that the pipe cutting can be carried out smoothly.
