Referring to the method of cutting the fume pipe (1) using a fume pipe cutter configured as described above are as follows.

First, the gap between the support rollers 21 and 22 is adjusted by using the gap adjusting mechanism 80 to fit the diameter of the fume pipe 1, and the fume pipe 1 is placed on the support rollers 21 and 22. . At this time, the fume pipe (1) is formed in the coupling portion (1a) having a large diameter at one end, the coupling portion (1a) is located outside the support rollers (21, 22) while the other end is the locking step (23) ) Put the fume pipe (1) in close contact with

Then, the operator adjusts the position of the support 40 in the longitudinal direction of the support rollers 21 and 22, that is, the longitudinal direction of the fume pipe 1 so as to fit the cut portion of the fume pipe 1, thereby completing the preparation work.

The cutter blade 52 is operated by repeatedly operating the first drive motor 30 to slowly rotate the fume pipe 1 and pressing the operation switch of the control unit 70 while the cutter 50 is turned on. The cutting is started by contacting the circumferential surface of the fume pipe 1. At this time, the cutter 50 cuts the peripheral surface of the fume pipe 1 to a low depth.

Then, when the fume pipe 1 is rotated once, the operator presses the operation switch of the control unit 70 once more so that the cutter blade 52 is advanced by a predetermined interval, and this process is performed every time the fume pipe 1 is rotated once. Repeat to advance the cutter 50 until the fume pipe 1 is completely cut.

And, if this process is repeated and the fume pipe 1 is completely cut, the cutter 50 can be retracted to complete the work.

At this time, the cutter blade 52 is supplied with the coolant stored in the water tank 91 through the coolant supply pipe 92 to cool the cutter blade 52, and the used coolant is a drain duct (below the cutter blade 52). 93) and is discharged to the outside.

The fume pipe cutter configured as described above cuts the fume pipe 1 using the cutter 50 while rotating the fume pipe 1 mounted on the support rollers 21 and 22, so that the fume pipe 1 is not only very convenient. , The cut surface of the fume pipe (1) is to be made to be cut exactly with the longitudinal direction of the fume pipe (1), there is an advantage that can accurately connect the fume pipe (1).

In addition, when the operation switch provided in the control unit 70 is pressed, the driving device 60 is operated to advance the cutter 50 by a predetermined distance, thereby preventing damage to the cutter 50 while increasing work efficiency. There is an advantage. That is, when the operator manually advances the cutter 50, the cutter 50 is advanced little by little and the cutting operation speed is slowed down, or the cutter 50 is advanced too much at once, so that the cutter blade 52 is fume pipe (1). ) Or may be damaged due to excessive load on the cutter blade (52). However, the present invention solves this problem, since the operator can advance the cutter 50 by an appropriate distance when the operator presses the operation switch once using the control unit 70.

This narrowness prevents the fume pipe 1 from being properly supported, or the spacing of the support rollers 21 and 22 is wider than the diameter of the fume pipe 1 so that the fume pipe 1 is sandwiched between the support rollers 21 and 22. There is an advantage that can be prevented.

In addition, the gap adjusting mechanism 80 is the lead screw 82 is interconnected by the sprocket 83 and the chain 84, if only the lead screw 82 provided on one side to rotate the lead screw 82 on both sides Is rotated together there is an advantage that can easily adjust the spacing of the support rollers (21, 22).

In addition, the support rollers 21 and 22 are provided with a support member 23 on which the end of the fume pipe 1 is caught, so that the fume pipe 1 mounted on the support rollers 21 and 22 is supported by the support rollers 21 and 22. To prevent the slip along the, there is an advantage that the cut surface of the fume pipe (1) can be made exactly flat.

In the present exemplary embodiment, the locking jaw 23 is illustrated as being fixed to the circumferential surfaces of the support rollers 21 and 22, but if necessary, a separate tube is provided on the circumferential surfaces of the support rollers 21 and 22. It is also possible to adjust the position of the locking step 23 by adjusting the position of the fitting tube.

Figure 6 shows another embodiment according to the present invention, by detecting the rotation of the fume pipe (1) mounted on the support rollers (21, 22) when the fume pipe (1) rotates to the control unit 70 Rotation detecting means 90 for inputting a control signal is further provided.

The rotation detecting means 90 has a structure such as a vision inspection device or a laser reader for reading a bar code, and is fixed to one side of the support frame 10 to draw a straight line 91 drawn on the circumferential surface of the fume pipe 1. Is configured to read).

Therefore, after placing the fume pipe 1 on the support rollers 21 and 22, and drawing a straight line 91 in the longitudinal direction on the circumferential surface of the fume pipe 1 using a magic or oil pen, the straight line 91 Is rotated together with the fume pipe (1). Therefore, when the straight line 91 is first sensed by the rotation sensing means and then again sensed, the rotation sensing means 90 determines that the fume pipe 1 is rotated one time and transmits a control signal to the control unit 70. Input, the control unit 70 operates the drive device 60 to advance the cutter 50 by a predetermined interval. This process is repeated until the fume pipe 1 is completely cut.

The fume pipe cutter configured as described above is different from the first embodiment in which the operator has to press the operation switch every time the fume pipe 1 is rotated, so that when the fume pipe 1 is rotated once, the cutter 50 is automatically advanced. It is possible to fully automate the work, and the operator does not need to monitor the work until the cutting work of the fume pipe 1 is completed, thus improving the productivity.
