Abstract:
The pipe rotary cutting device of this invention comprises shifter means which is operative to rotate a cylindrical body relative to a main shaft to thereby rotate an internal gear secured to the cylindrical shaft. The rotation of the internal gear rotates pinion gears secured to the main shaft to thereby rotate eccentric shafts provided coaxially with the pinion gears. Then the rotation of the eccentric shafts is converted by sliders into radial movements. A cutting tool as well as disc cutters are provided on the sliders respectively through a cutting tool holder and cutter holders. The pipe rotary cutting device of such arrangement enables the steps of chamfering and cutting to be carried out simultaneously, and accordingly the chamfering step of removing the outward burrs created in cutting a pipe is totally unnecessary.
