On the other hand, the calibration means 500, as shown in Figure 2, is installed between the transfer means 300 and the anti-rotation means 10 so that the tube 100 is calibrated in a straight state and transported.

The detailed configuration of the calibration means 500 is composed of a horizontal calibration roller group 510 and a vertical calibration roller group 520.

As shown in FIG. 3, the horizontal straightening roller group 510 includes two rows of left and right rows of rollers 501 formed in the outer periphery of the groove 501a rounded to insert the outer peripheral surface half of the tube 100. Arranged so as to be rotated in a horizontal state so that the left and right sides of the tube 100 is in a straight state.

In addition, the vertical calibration roller group 520, as shown in Figure 3, the roller 511 formed in the outer periphery of the groove 511a rounded so that half of the outer peripheral surface of the tube 100 is inserted into the jig zag up and down It is arranged to be two rows and installed to rotate in a vertical state so that the upper and lower sides of the tube 100 is in a straight state. In addition, the vertical calibration roller group 520 is connected to the drive motor 320 of the conveying means 300 is driven.

Here, the reason that the correction means 500 is necessary, if the metal tube 100 is wound on the tube winding machine 200, when it is unwound again, the tube 100 immediately maintains the straightness in the curved state It becomes impossible.

Therefore, when the tube is processed through the processing means 400 after passing the conveying means 300 in a state where the straightness is not maintained, the processing accuracy of the pin 110 is significantly reduced.

In addition, of course, the interval between the rollers constituting the straightening means 500 may be configured to be adjusted manually or automatically so as to be able to flexibly cope with a tube having various diameters.

The cutting means 600, as shown in Figure 15, serves to cut the tube 100, the fin 110 is processed by the processing means 400 by a predetermined length unit.

The configuration of the cutting means 600 is a plate 610 on which the accessory is mounted, the cutting means 620 for cutting the tube, and the guide means 630 for guiding the tube 100 passing through the cutting means 600. Is done.

The plate 610 has a predetermined size installed to be spaced apart from the processing means 400 by a predetermined distance.

The cutting means 620 cuts the tube 100 by the cutting signal of the adjusting means 30.

The cutting means 620, the upper and lower cutters 621 and 622 for cutting the tube 100 from the upper or lower, and the upper or lower cutters 621 and 622 for cutting, respectively, up and down The solenoid valve 625 controls the upper and lower cylinders 623 and 624 and the upper and lower cylinders 623 and 624 to move to the upper and lower cylinders.

Here, the movement of the cutter may be made at the same time up and down, but one of the upper or lower portion may be a transfer cutter and the other side may be of a fixed blade structure.

The guide means 630 may be formed on the upper surface of the plate 610 by a first tube guide pipe 631 through which both ends are installed to be in line with the tube 100 and a connecting rib 632. A gap t between the second tube guide pipe 632 and the first tube guide pipe 631 and the second tube guide pipe 632 which are installed at a predetermined distance from the end of the first tube guide pipe 631. )

Cutting means 600 is configured as described above by using a saw blade rotated by a drive motor to take some time to cut and the cutting chips scattered to enable instant cutting using a cutting mold. At this time, the cutting stops the drive motor of the transfer means 300 and is transferred again when the cutting is completed.

Accordingly, in a cutting operation using a conventional saw blade, the tube 100 is temporarily clamped without stopping the driving motor of the conveying means, and then the cutting operation is performed while the cutting means is reversed while driving the cutting means in a driving state, thereby continuously processing. Although this could be done in the present invention, such a clamping is not necessary.

In addition, the need for clamping eliminates the need for clamping / release means as well as a separate cutting plate and no forward or backward means for advancing the cutting means together with the tube.

As described above, in the present invention, the processing means also used a pneumatic chuck 410 which has a very high response rate to the signal for the hydraulic chuck.

On the other hand, the take-out means 700 serves to take out the unit tube 100 cut in a predetermined length unit by the cutting means (600).

The adjusting means 30 sends a jaw 430 opening and closing signal to the pneumatic unit 480 according to a predetermined process, and responds to a faster one of the unit feed signals transmitted from the driving motor 320 and the encoder 170. It comprises a controller (not shown) for sending a cutting operation signal to the cutting means (620).

Referring to the operation of the present invention using the configuration described so far as follows.

First, one end of the tube 100 wound around the tube winder 200 passes through the first tube guider 150, and then passes through the pull roller group 310 constituting the transfer means 300, Pass the horizontal calibration roller group 510 and the vertical calibration roller group 520 constituting the calibration means 500.

The tube of the pneumatic chuck 410 constituting the processing means 400 is the end of the tube 100 passing through the horizontal calibration roller group 510 and the vertical calibration roller group 520 constituting the calibration means 500 as described above. It is to be introduced into the through hole (410a).

Next, the jaw 430 installed on the pneumatic chuck 410 of the processing means 400 is moved to a predetermined value in the direction of the center of the pneumatic chuck 410 so that the cutter 450 contacts the outer circumferential surface of the tube 100. In addition, the support roller 470 is also in contact with the outer circumferential surface of the tube 100 so as to center the tube 100 and manually advance the jaw 430 in the center direction, while rotating the pneumatic chuck 410 by hand with a pin ( 110) Set the shape.

After the above operation is completed, the drive motor 420 constituting the motor 481 and the processing means 400 of the pneumatic unit 480 is driven to reach a predetermined speed. The traction roller group 310 is rotated by applying power to the driving motor 320 constituting the transfer means 300.

As described above, when the traction roller group 310 starts to rotate, the tube 100 starts to be transported at a constant speed by the traction force of the traction roller group 310.

As described above, when the driving motor 420 constituting the processing means 400 starts to be driven, the cutter 450 and the roller 470 rotate together along the outer circumferential surface of the tube 100 that is forward moving. 450, a fin 110 having a diameter larger than its outer circumferential surface is formed on the outer circumferential surface of the tube 100.

Here, as shown in FIG. 14, the intervals for forming the fins 110 on the outer circumferential surface of the tube 100 may be formed to be spaced apart by a predetermined length at regular intervals.

Such adjustment is made by the control of the adjusting means 30 as previously determined.

That is, the jaw 430 installed in the pneumatic chuck 410 by the pneumatic cylinder 490 constituting the processing means 400 may be controlled to move in the direction of the edge of the pneumatic chuck 410.

In other words, in the region of the tube 100 forming the fin 110, the pneumatic cylinder 490 is controlled to move the jaw 430 in the direction of the center of the pneumatic chuck 410 and the fin 110 is not formed. In the region of the tube 100, the pneumatic cylinder 490 is controlled to move in the edge direction of the pneumatic chuck 410.

Next, the tube 100 having the fin 110 is advanced by the conveying force of the conveying means 300 and passes through the region of the cutting means 600.

And, the process of passing through the cutting means 600, the tube 100, the pin 110 is formed as follows.

When the front end of the tube 100 passes through the encoder 170, the encoder 170 starts counting to measure the passage length of the tube 100, the drive motor 320 of the transfer means 300 is When it is determined that the number of rotations of the tube 100 of the predetermined length has passed, it transmits a one-unit feed signal indicating that the length of one unit for cutting has passed to the adjusting means 30.

The adjusting means 30 receives this one-unit transfer signal and sends an operation signal to the cutting means 620, and the cutting means 620 cuts one unit of the tube.
