Document Type and Number:
Japanese Patent JP2015020236
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pipe cutting device which makes exchange of an outer blade unnecessary even when an outer diameter of a pipe to be cut is changed, and can reduce a time required for changeover.SOLUTION: A pipe cutting device includes: an outer blade 1 which is provided with an inner circumferential surface 11 assuming at least a part of a circle larger than the largest diameter of the pipe 100 to be cut and is located such that the inner circumferential surface 11 faces an outer circumferential surface of the pipe 100; and an inner blade 2 which is a rotation body having an outer diameter smaller than the minimum inner diameter of the pipe 100 and is arranged such that one side lateral surface forms a gap according to the thickness of the pipe 100 between a cutting surface 12 of the outer blade 1 and one side lateral surface. The pipe 100 is retained freely movably within a surface vertical to a shaft direction by a pipe retention member 3. The outer blade 1 is supported freely rotatably by an outer blade support member 4. The inner blade 2 is driven by an inner blade driving member so as to be moved along a radial direction and a circumferential direction of the inner circumferential surface 11 of the outer blade 1 while being rotated.
