Abstract
PURPOSE: To cut a spiral groove with a simple operation on the inner surface of pipe by means of a ring-type groove cutting device with spiral groove cutters provided on its outer circumference, and rotatably slipped around a shaft.
CONSTITUTION: A groove machining device 1 applicable to the inner surface of pipe is installed around shaft 2a of a rod 2. A groove cutting device 5 is rotatably slipped in, the smaller diameter portion 2a at the top portion of the rod 2, the outer diameter of which is somewhat larger, and is largest at the center, than the inner diameter of the pipe P being internally grooved. A number of spiral groove cutting tools 8 are provided around the outer circumference of the cutting device 5. A screw 9 is threaded from the front end portion of the smaller diameter 2a, further ahead of the bearing metal 3, on which a nut 10 is screwed on. By inserting the rod 2 into the pipe P, and driving it ahead, the device 5 is forced to rotate generating a number of spiral grooves by means of groove cutting tools 8.
