Title:
CUTTING DEVICE FOR THIN THICKNESS METAL PIPE
Document Type and Number:
Japanese Patent JP3404058
Kind Code:
B2
Abstract:

PURPOSE: To provide a cutting device, capable of smoothly cutting a metal pipe without producing a burr in a cut face.
CONSTITUTION: A pair of collet chucks 10a and 10b, nippedly holding a metal pipe A by diameter-reducing plural collets 12 arranged at equal intervals in a peripheral direction, is coaxially located so that the collets 12 can be faced in an axis direction. On the one hand, a cutter 43 of a cutting off bite state is fitted to a cutter holder 39, oscillatedly supported with the end surface eccentric position of a tubular rotor 31, provided coaxially with the collet chucks 10a and 10b, as a center. A cutting off blade on the tip is pierced in a metal pipe A, nippedly held by the collet chucks 10a and 10b, by oscillating the cutter 43 in the side direction at the rotation initial stage of the rotor 31. The cutter 43 is retained in a condition where the cutting off blade can be faced in the metal pipe A, the cutter 43 is made to be turned one time or more around the circumference of the metal pipe A, and the metal pipe A is cut by cutting a peripheral edge in the end surface between both side cutting blades of the face of the cutting off blade and the collet.
