Abstract

PURPOSE: To eliminate the need for a clamping mechanism of a cutter, by a method wherein the revolving force of the cutter is transferred from an outside of a steel pipe, and a roller, which produces a repulsion force against a force to press a blade, and a cutter are located in a horizontal position, and are pressed by means of jack.
CONSTITUTION: With a motor driven, a hydraulic oil is fed to a cylinder oil feed hole 25, and acts on a double cylinder for pressurization. A press plate 26 is then pushed backward along a guide 27, and an arm 32 expands a roller 31 centering around a pin 27 through the working of arms 28W30. The roller 31 expands diagonally to the outside through the circular motion of the arm 32, and a repulsion force, which presses a cutter 33 along an inner circumference of a steel pipe, is generated. With the hydraulic cylinder pressurized, the roller 31 and the cutter 33 are pressed against the inner circumference of the steel pipe as they expand to said inner circumference. The cutter 3 is turned through the rotation force transmitted by means of a coupling shaft, and this permits cutting of a steel pipe.
