PROBLEM TO BE SOLVED: To provide a tube cutting device which, even if there is a collapse at a part of a tube, can draw the collapsed part of the tube from a taken-up tube without catching thereof by a device and cut the collapsed part at a specified dimension.SOLUTION: A tube cutting device 1 having a cutting mechanism part 40 including a grip drawing part 60 which grips a part of a tube C from a taken-up tube C1 and draws only a specified length from the tube, a grip fixing part 50 which grips and fixes a part of the tube C, and a cutting part 70 which cuts the tube C. The cutting device further has: a tube direction gradually changing part 10 which adjusts a clearance between the taken-up tube C1 and the cutting mechanism part 40, and guides the drawn tube C to the cutting mechanism part 40 while gradually changing a direction of said tube; and at least one tube insertion guide part 30 which is provided in a guide zone for the tube and forms a tube insertion guide hole 31 of which a dimension is so adjusted as to involve a width larger than an outer diameter width of the tube C enlarged by collapse of the tube C.SELECTED DRAWING: Figure 2 |
