On the other hand, when the refrigerant pipe proceeds, the cylinders 420 and 420a lift the upper fixtures 430 and 430a to increase the size of the circular groove formed by coupling the semi-circular grooves 431, 431a, 441 and 441a. When the refrigerant pipe is tightly held, the upper/lower fixtures (430,430a, 440,440a) are brought into close contact by lowering the upper fixtures (430,430a) so that the semicircular grooves (431,431a,441,441a) are combined and formed. The size of the circular groove is formed to match the outer diameter of the refrigerant pipe.

And a rail 411a is installed in the lower part of the fixing frame 410a of the supporting means 400a located at the rear of the respective supporting means 400 and 400a as shown in FIG. 4B so that the fixing frame 410a moves forward/backward. The rear of the fixing frame 410a is connected to the cylinder 412a so that the fixing frame 410a can move forward/backward along the rail 411a according to the operation of the cylinder 412a. By doing so, by pulling the coolant tube (T) by operating the cylinder (412a) when the cut surfaces of the coolant tube (T) are spaced apart from each other, the coolant tube (T) is completely separated from the cut surface as well as some uncut The cut part will be completely cut off.

It is designed to be cut inwardly from the side.

The reason why the circular cutting knife 520 rotates together with the rotating body 510 and cuts the refrigerant pipe as described above is to cut the refrigerant pipe beautifully without generating burns or chips in the process of cutting the refrigerant pipe.

And on one side of the rotating body 510, the cutting knife 520 and the cutting knife 520 and the cutting knife position moving piece 560 are installed, and the structure of the cutting knife position moving piece 560 is, the cutting knife 520 is When the sleeve 550 moves forward by forming an inclined surface 561 having a downward inclination as it comes from the front to the rear of the side to be installed, the moving sleeve 550 is a shear knife while pressing the positioning piece 560. By moving the 520 to the refrigerant pipe, it is cut inward from the outer peripheral surface of the refrigerant pipe while in contact with the refrigerant pipe.

However, since a long hole 562 through which the shearing knife 520 can move is formed on the front end surface of the rotating body 510, the shearing knife 520 moves within the long hole 562 width, and the A shaft 563 is installed in the center of the shear knife 520 , and the shaft 563 is connected to the cutting knife position moving piece 560 .

The rotating body driving means 600 of the present invention serves to rotate the refrigerant pipe cutting means 500, and the configuration of one embodiment is a pulley ( A motor 610 having a 620) is installed, and the pulley 620 is made by installing a power transmission member 630 that is connected to the pulley 570 installed on the rotating body 510 and installed. When is operated, the rotation body 510 is rotated by being transmitted to the pulley 570 of the rotation body 510 through the pulley 620 and the power transmission member 630 interlocked therewith.

The power transmission member 630 is possible as long as the power of the motor 610 can be transferred to both pulleys 570 and 620, and the pulley is also a chain sprocket, a time belt pulley, a V belt pulley, a flat belt pulley, etc. A variety of choices are available.

The cutting knife operating means 700 of the present invention moves the cutting knife 520 toward the coolant pipe or operates the sleeve 550 to be spaced apart from the coolant pipe, the configuration of one embodiment is shown in FIG. 4A As shown, the support 710 is fixedly installed on the movable body 200, and the support 710 is provided with an actuator 720 for pushing the sleeve 550 forward or pulling the sleeve 550 backward at the tip of the support 710, the support ( On one side of the 710, a cylinder 730 for moving the support 710 forward/backward is installed.

In the above configuration, since the sleeve 550 in which the actuating tool 720 is located has a groove 551 formed along the circumferential surface thereof, the cylinder 730 in the state where the actuating tool 720 is located in the groove 551. When is operated, the support 710 moves while moving the actuator 720 forward or backward. And the moving distance of the support 710 is up to the stopper 740, and when the support 710 is moved to the stopper 740, the sleeve 550 is in a state of completely pressing the cutting knife position moving piece 560.

An embodiment of cutting the refrigerant pipe using the refrigerant pipe cutting device of the present invention as described above will be described below.

- under -

Refrigerant pipe manufacturing equipment described in the present invention is a conventional technology that has already been used, and detailed description thereof will be omitted and only the refrigerant pipe cutting device of the present invention will be described.

First, as the refrigerant pipe manufactured in the refrigerant pipe manufacturing facility is withdrawn through the refrigerant pipe withdrawing means 900, the refrigerant pipe measuring means 910 measures the length of the refrigerant pipe, and the measured refrigerant pipe is each of the supporting means It proceeds through the semicircular grooves (431,431a, 441,441a) of (400,400a) and the refrigerant pipe progress hole 511 of the rotating body 510, and at the same time, the moving body 200 is also the moving body moving means ( 300) proceeds at a speed equivalent to the production speed of the refrigerant pipe manufactured in the refrigerant pipe manufacturing facility, and at the same time, the rotating body 510 is rotated by the rotating body driving means 600 .

As described above, when the rotating body 510 is rotated and the moving body 200 is moved while the moving body 200 is detected by the first sensor S1, the control unit 800 commands the operation of each of the supporting means 400 and 400a. When the moving object 200 is detected by the second sensor S2 in a state where the refrigerant tube is firmly held and the refrigerant tube is held, the cutting knife operating means 700 is operated to remove the cutting knife 520 from the sleeve 500. It moves toward the refrigerant pipe and cuts from the outside of the refrigerant pipe to the inside.

At this time, the plurality of support holes 540 installed at the tip of the rotating body 510 support the outer circumferential surface of the refrigerant tube, thereby preventing the refrigerant tube from being deformed and safely supporting the refrigerant tube.

And, since the cutting knife 520 rotates together with the rotating body 510, it cuts along the outer circumferential surface of the refrigerant pipe, so that no burns or chips are generated on the cutting surface during the cutting process, and the cutting blade is beautifully cut.

As described above, when the cutting of the refrigerant pipe is completed and the moving body 200 is detected by the third sensor S3, the control unit 800 commands the operation of the cylinder 412a to lock the fixing frame 410a, thereby locking the refrigerant. The cut surfaces of the tube are spaced apart from each other.

After that, when the moving body 200 is detected by the fourth sensor S4, the control unit 800 detects the completion of cutting the refrigerant pipe, and then the cut refrigerant pipe is discharged to the outside.

However, when discharging the refrigerant pipe to the outside, a separate refrigerant pipe drainage means (not shown) can be installed and used.

The refrigerant pipe cutting device of the present invention as described above, as described in the above effect, allows cutting in real time while continuing production without stopping the manufacturing equipment in cutting the refrigerant pipe, and also cutting the refrigerant pipe In the process, there is no burr or chip generated on the cut surface, and there is an advantage in that the end can be cut bluntly without changing the shape of the cross section.
