PIPE END BEVELING MACHINE AND PIPE END BEVELING METHOD

PROBLEM TO BE SOLVED: To provide a pipe end beveling machine light-weighted and capable of performing beveling work for a pipe end simply, easily and with good accuracy. SOLUTION: This invention provides the pipe end beveling machine 1. A suitable number of paired clamp members 2 are arranged at equal spaces on the same circumference. The paired clamp members 2 are inserted in a pipe P end to be subjected to beveling work, and radially bulged outward by a bulging mechanism 3. A cutting mechanism 5 is disposed at a designated space in the direction of shaft center from the clamp members 2. In the cutting mechanism 5, one or more rotary blades 4 are disposed in superposition on the same shaft to freely revolve around the same shaft center as the center of the paired clamp members 2. The machine is provided with a slitting mechanism 6 for moving the rotary blades 4 of the cutting mechanism 5 to be close to and away from the center of revolution. The cutting mechanism 5 is pivoted to adjust an angle to the pipe end P of the rotary blades 4. Thus, beveling machining can be performed for the pipe end easily and in a short time as much as possible even in a narrow place.
