Description

Tube

The present invention relates to a piping device, and more particularly, a pipe formed by a pipe tube undergoes a calibration process through a primary straightener, followed by a secondary pipe straightener so that the pipe has a precise dimension and shape. It is about.

In general, the pipe making device is a pipe pipe for forming a metal plate wound on the core and welded in the form of a pipe, a pair of opposite rollers are rotated to correct the pipe conveyed from the pipe pipe, and the corrected pipe It consists of a cutter for cutting to length, a conveyor for transporting semi-finished products formed between the respective processes, and a polishing machine for processing the surface of the pipe on which the cutting work is completed.

1 is a structural diagram of a pipe straightener according to the prior art, and FIG. 2 is a pipe manufacturing process drawing according to the prior art. As shown in FIG. 1, a conventional pipe straightener is connected to a pair of rollers 10 facing up and down inside. It is connected between the rotating frame 20 and the vertical column 31 while being formed in a set, but at least two or more rectangular rotation frame 20 installed in the horizontal direction, the center is penetrated to pass the pipe between the center It consists of a rotating shaft tube 21 rotatably installed in the vertical column 31 and separate driving means (not shown) connected to the rotating shaft tube 21. Therefore, when the drive means is operated, the rotating shaft tube 21 and the rotating frame 20 is rotated, and the roller 10 installed inside the rotating frame 20 also rotates together, and the rotating shaft tube 21 Passing the pipe into the inner surface of the pipe while being passed through the roller 10 is rotated to be corrected while hitting the surface of the roller (10).

Looking at the operation of the conventional pipe straightener having the above configuration in detail as follows.

The saddle-shaped roller 10 having a concave center portion has a height adjustment by a screw rod 15 attached to the rotating frame 20 and a rotating manipulator 11a formed outside the screw rod 15. do. That is, when the screw rod 15 is rotated, the shaft tube 12 screwed to the outer circumferential surface is moved up and down in the rotating frame 20 to adjust the height of the roller 10.

At this time, the gear 13a fixed to the outer circumferential surface of the shaft tube 12 is also moved up and down together with the roller 10 in a state of being engaged with the angle adjusting gear 13b.

Thus, even after the height adjustment is completed according to the diameter of the pipe to be calibrated, there is also a time to adjust the horizontal angle separately according to the pipe to be calibrated, in this case, the rotary shaft 14 and the rotary shaft 14 installed on one side of the screw rod (15) It is possible to use the rotary operation portion (11b) formed at the top of. That is, when the rotary operation unit 11b is rotated, the lower angle adjustment gear 13b connected to the rotary operation unit 11 also rotates, and the gear 13a meshed with the angle control gear 13b is rotated. The horizontal angle of the roller 10 is adjusted.

After adjusting the height and the horizontal angle of the roller 10 according to the diameter of the pipe supplied in this way, by operating the drive means connected to the pulley 21 of the rotating shaft tube 25, the rotating frame 20 is rotated, The roller is calibrated by rotating the outer circumferential surface of the pipe passed between the rollers 10 while the roller 10 installed inside the rotary frame 20 rotates simultaneously with the rotary frame 20.

At this time, the roller 10 rotates together with the rotating frame 20 to provide a heat treatment to the pipe surface by the frictional action to remove stress from the welded portion and to increase the strength of the pipe surface.

As shown in FIG. 2, this conventional pipe manufacturing process is a metal plate wound on the core 101 is formed and welded in the form of a pipe while passing through the pipe tube 102, the rotating frame 20 in the straightener 103 The pipe is calibrated while removing the stress of the welded portion by the rotation of each pair of rollers 10 installed in the inner side of the roller. It is composed of a series of processes to complete the piping process by processing the surface of the pipe sent to 107 and the calibration work is completed to be released by the conveyor 108.

However, in the conventional pipe manifold as described above, a pair of rollers facing each other at a predetermined angle rotates the outer periphery of the pipe and applies pressure to transfer it forward, so that the linear straightness and dimensions of the pipe can be corrected. As the pipes passed between are minutely flowed from side to side between the rollers, there is a problem that the pipes to be corrected are not corrected to the correct dimension and shape of the circle.

The present invention is conceived to solve such a conventional problem, the tubing device according to the present invention is installed so as to be revolved by the tube is formed and welded in the form of a pipe while the metal plate is passed, and the drive motor connected to one end to the upper side of the base The outer circumferential surface of the pipe passing through the center of the pair of rollers while being rotated simultaneously with the rotating frame while a plurality of rollers installed up and down facing the inner side of the rotating frame are firstly corrected by friction of the rollers to some extent. The primary straightener and the linear straightener and the linear straightener and the linear corrector to be installed in series with the primary straightener and a pair of feed rollers are installed in the front and rear to rotate in conjunction with the drive motor and the pair of feed rollers From the first calibrator inwardly into a circular through passage formed by engaging and rotating Secondary calibrator which presses the conveyed pipe and passes through the through-holes of a plurality of dies installed between the conveying rollers and straightens the diameter so as to recalibrate to a more precise dimension and shape, and the first and second calibrators It consists of a cutter for cutting the finished pipe to a proper length, a conveyor for transporting the semi-finished products formed between each process, and a grinding machine for processing the surface of the pipe which has been cut by the conveyor. The technical task is to provide a piping system for calibrating pipes.
