Description

Pipe Purifier {APPARATUS FOR REFORMING A PIPE}

The present invention relates to a pipe tuber, and more particularly, to a pipe tuber to be cut to a certain length in a state of correcting the straightness of the pipe wound on the drum.

In general, the pipe is generally formed by one of the drawing processing method and the forming processing method, of which copper pipes used for small diameter pipes, such as refrigerant pipes or heat exchange tubes, are usually drawn out. It is being molded.

The free end of the drawn pipe passing through the die from the idler of the conventional pipe drawing device for such pipe drawing is engaged with the clamping jaw connected to the drum driven by the motor and pulled by the pulling force by the rotational force of the drum so that the pipe passes through the die. While the diameter is reduced and configured to wind the drum. The pipe is preferably formed in a straight line in a unit of a certain length, but in the case of a small and medium-sized business, which has a relatively narrow working space, the above-described drawing apparatus is usefully used.

In other words, the pipe wound on the drum as described above is transferred to the pipe drawing means and the pipe cutting means again, the cutting process to the required length.

However, when the pipe is taken out while the pipe is wound in the drum, the pipe is often bent in the winding direction, which causes many problems in the straightness of the pipe.

Accordingly, an object of the present invention for solving the above problems is to provide a pipe canister to cut to a certain length in a state of correcting the straightness of the pipe wound on the drum.

According to an aspect of the present invention, there is provided an uncoiler in which a pipe is wound, a conveying unit for drawing out the pipe, and a cutting unit for cutting a pipe drawn out through the conveying unit.

That is, when the main body 10 rotates, the supply and discharge guide pipes 14 and 16 and the vertical movable plate 18 through which the pipes P pass except for the pipes P are rotated together. In the outer diameter of the pipe (P) is to be able to correct the bending of the pipe (P) by rubbing against the inner diameter of the supply and discharge guide pipe (14, 16) and the inner diameter of the through hole 20 of the vertical movable table (18). .

5 and 6 are views illustrating the configuration of the cutting unit D in more detail.

As shown in Fig. 5 and 6, the cutting unit (D) through the above-described calibration unit (B) in the state of straightness is corrected in the operation of the transfer unit (C) withdrawing the pipe (P) being drawn out A unit for automatically cutting by the length set in the control unit (not shown), including a carriage 50, a rotating body 54, a slider 62, a split operation 66 and a cutter 68 Configure.

The carriage 50 is the power of the first cylinder 52 in the state supporting the rotating body 54, the slider 62, the splittable 66 and the cutter 68 constituting the cutting unit (D) It is a means for reciprocating before and after and moving so that the cutter 68 can be located in accordance with the cutting length of the pipe (P) set in the control unit. At this time, the first cylinder 52 is preferably configured to drive in accordance with the signal of the controller after the pipe (P) being drawn out through the cutting unit (D) is caught by the stopper (74).

The rotating body 54 is a means for rotating by the power of the motor 58 in the state supported by the carriage 50, a hole for passing the pipe (P) in the center of the rotating body (54) The guide tube 56 in which 56a) was formed is penetrated. At this time, the rotatable member 54 is rotatably configured such that the outer diameter of the pipe P is rotated such that the main body 10 of the calibration unit B is rotated. This is to correct the deflection of (P) once again.

The slider 62 is a means for reciprocating before and after riding the outer diameter of the rotating body 54 by the power of the second cylinder 60 while being fitted to the outer diameter of the rotating body 54. The rear of the slider 62 is formed with a groove 64 for assembling the split operation table 66, the inner peripheral surface of the groove 64 is tapered (64a) to gradually increase in diameter from the inner side to the outer side It is preferable to form.

The split operation table 66 is collected inward in accordance with the pressing operation of the pressing roller 72 according to the front and rear movement of the slider 62 in the assembled state in the groove 64 of the slider 62. Means to perform.

The press roller 72 is a taper 64a formed on the inner circumferential surface of the groove 64 according to the movement of the slider 62 in a state located between the groove 64 of the slider 62 and the split operation table 66. Press the by the angle of the taper (64a) in close contact with the) and presses the partition operating table 66 to raise and lower the partition operating table (66).

The cutter 68 is coupled to the shaft 70 to the split operation 66, cutting the pipe (P) passing through the guide tube 56 in accordance with the operation that the split operation 66 is gathered inward. Will be processed.

Hereinafter, the operation of the pipe canister according to the present invention will be described with reference to FIGS.

First, the pipe (P) wound on the uncoiler (A) is drawn out to the cutting unit (D) in accordance with the operation of the transfer unit (C), and then cut by a predetermined length by the operation of the cutting unit (D). In this case, the pipe (P) is to be transferred to the cutting unit (D) in the straight state of the pipe (P) from the calibration unit (B) in the drawing process.

Specifically, the pipe (P) passing through the supply guide pipe 14 of the main body 10 to the transfer unit (C) through the discharge guide pipe 16 through the through hole 20 of the vertical movable table 18. In this case, the main body 10 rotates by receiving the power of the motor 30 and rotates the supply and discharge guide pipes 14 and 16 and the vertical movable plate 18 together. The outer diameter of (P) is to rub the inner diameter of the supply and discharge guide pipes (14, 16) and the inner diameter of the through hole 20 of the vertical movable table 18 to correct the bending of the pipe (P).

In addition, since the pipe P is bent in the winding direction of the uncoiler A, even if the through hole 20 is positioned at the center of the feed guide pipe 14, the pipe P is moved vertically. ) Can be attached to the periphery of the through hole 20, in this case, using the upper and lower bolts 26 and 28 to press the vertical movable table 18 upward and downward, and the position of the through hole 20 By adjusting according to the bending angle of the pipe (P) it is possible to pass the pipe (P) without interference even if the pipe (P) is bent.

Subsequently, the pipe P passing through the calibration unit B passes through the guide tube 56 installed through the cutting unit D, preferably the rotating body of the cutting unit D, thereby cutting the cutting unit D. When the first cylinder 52 is driven by a signal from the controller and the carriage 50 is moved forward by the signal of the controller, the cutter 68 is moved to the cutting length of the pipe P set in the controller. Will be positioned to fit. At this time, the rotating body 54 is rotated by the power of the motor 58, the outer diameter of the pipe (P) to the inner diameter of the guide tube 56 to correct the straightness once again.

Subsequently, after the cutter 68 is in the correct position, the second cylinder 60 is operated to move the slider 62 forward, and thus, between the groove 64 of the slider 62 and the splittable 66. The pressure roller 72 located is pressed by the angle of the taper 64a formed on the inner circumferential surface of the groove 64 and presses the dividing operating table 66 to raise and lower the dividing operating table 66. Accordingly, the cutter 68, which is coupled to the shaft 70 on the split operation table 66, cuts the pipe P.
