When the CR tube of the sample is cut as described above, the CR tube is clamped from both sides with a vise and fixed. The cut end faces of the cut portions receive a force in a direction in which the cut end faces approach each other due to a vice gripping force. For this reason, the saw blade of the hand saw may be stuck between the cutting end faces and may not move or bend, thereby causing a problem that the cutting operation cannot be performed smoothly. In addition, since the worker performs cutting while holding the pipe or a hand saw that is not supported by a vise in his hand, the workability is poor, such as having to operate the hand saw in a very unstable posture. was there.

An operation process for cutting the pipe P by using the pipe half-severing cutting device configured as described above will be described with reference to FIG. First, as shown in FIG. 2A, the cored bar 5 is moved to the side to make the cored bar 10 swingable.
After the core 2 is inclined obliquely downward, the pipe P is attached to the core 10 in such a manner that the other end 12 of the core 10 is inserted into the pipe P to be cut. Thereafter, when the other end 12 is lifted and the core 10 is positioned horizontally, the pair of abutting portions 21 and 22 abut on the outer surface on one side of the tube P facing upward, and the tube P is moved inward by the core 10. From a pair of contact portions 2
Since it is clamped and fixed from the outside by 1, 22,
In order to maintain this state, the cored bar 5 is returned to the original position, and the cored bar 10 is held in a horizontal state as shown in FIG. When the cutting machine 30 is moved along the rails 6 and 7 while operating the cutting machine 30 and rotating the saw blade 31, the saw blade 31 moves the pair of abutting portions 21 and 22 between the core metal 10 and the core metal 10.
In the length direction, and the mandrel 10 and the pair of contact portions 21 and 2
One side of the tube P supported between the two is cut off. After cutting one side surface, the metal core supporting rod 5 is moved to the side to remove the metal core 1.
0 is set in a swingable state, and the tube P, which still retains a tubular shape, is rotated by 180 ° around the cored bar 10, and the tube P is again sandwiched from the inside and the outside with one side surface having been cut facing downward. It is fixed and the cored bar 10 is kept horizontal. Then, when the side surface of the pipe P is cut in the same manner as above, the pipe P is cut into a half-split state.
