The present invention relates to a burr removing device of the tube, more specifically to cut the pipe to a certain length during the continuous production of the pipe, this time the burr of the tube to remove the chips and burrs generated from the cutting surface of the pipe Relates to a device.

Generally, pipes are mainly used for transporting fluids (gas, liquid) or powder, and their types and uses vary.

Among the pipes, there is a metal pipe manufactured by forming and welding a metal plate with a pipe tube. Looking at the manufacturing method thereof, iron strips (STRIP) wound in a coil shape are sequentially released and formed into a circle in the pipe tube, and both ends are formed. After welding, the bead surface produced by welding is polished and the roundness is corrected. After the roundness is corrected, the rounded metal is cut to a certain length, and the cut metal pipe is straightened.

The metal pipes (hereinafter referred to as "pipes") whose straightness is corrected may be deformed into a square or a specific shape, and the outer surface is polished and cut to the size of the final product, and then checked for abnormality of the product. Will be shipped.

However, in the related art, since the worker manually removes the burrs generated on the cut surface generated when the pipe is cut to a certain length, the workability is remarkably deteriorated.

The present invention has been made to solve such a conventional problem, the purpose is to suck the chips generated during the cutting process of the pipe to automatically remove the burrs generated on the cutting surface of the pipe from the work line, formed at the end of the pipe The burr is to provide a burr removing device of the tube machine to be processed.

The present invention for achieving this purpose is to supply a steel strip strip in sequence to form a circular tube in the tube, weld the formed both ends, polish the welded both ends and cut to a certain length to produce a pipe And a suction means installed to suck chips generated from the cut pipe, and a burr removing means installed at a rear end of the suction means and removing burrs formed at an end when the pipe is cut.

In addition, the suction means is a suction nozzle for generating a suction force by the compressed air supplied from the air compressor is located at the pipe end when the pipe cut to a predetermined length on the transfer line, and one end is fixed to the suction nozzle The other end is one side of the support frame fixed on the frame of the transfer line, and the suction nozzle circular arc movement at a predetermined angle so that the suction nozzle fixed to the support frame can be positioned at the end of the pipe when the pipe passes through It consists of a front and a back cylinder installed in the.

In addition, the burr removing means is formed with a through hole through which the pipe passes in the center, the brush member consisting of a plurality of brushes which are installed toward the through hole in contact with the burr at the end of the pipe, and the brush member to rotate It consists of a drive motor.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 is a view showing the burr removing device of the tube according to the present invention.

As shown, the burr removing device of the pipe-making machine of the present invention receives iron plate strips sequentially and forms them in a circle in the pipe-making machine, welds the molded ends, and polishes the welded ends to cut the pipe to a certain length. ) Is installed in the process line for producing, suction means 10 installed to suck the chip (C) generated from the cut pipe (P), and installed at the rear end of the suction means 10, pipe (P ) Is composed of a burr removing means 20 for removing the burr (B) formed at the end during cutting.

In addition, the suction means 10 is located at the end of the pipe (P) when the pipe (P) cut to a predetermined length on the transfer line, and generates a suction force by the compressed air supplied from the air compressor (14) Suction nozzle 11, one end is fixed to the suction nozzle 11, the other end is a support frame 12 is fixed on the frame of the transfer line, and the suction nozzle (fixed to the support frame 12) 11) consists of the front and rear cylinders 13 installed on one side of the suction nozzle 11 to arc at a predetermined angle so that the pipe (P) can be located at the end of the pipe (P) at the time of passage.

That is, the suction nozzle 11 is positioned at the end of the pipe (P) every time the pipe (P) passes while arcing at an angle while being supported by the support frame (12) by the front, reverse cylinder (13). The chip C generated in the process of cutting to a predetermined length is discharged to the outside through the suction nozzle 11.

In addition, the burr removing means 20 has a through hole 21a through which the pipe P passes in the center, and is installed toward the through hole 21a to the burr B at the end of the pipe P. It consists of a brush member 21 made up of a plurality of brushes (21b) in contact with, and a drive motor (22) for rotating the brush member (21).

In addition, even if the brush 21b is formed on only one side, the brush member 21 is rotated by the driving motor 22 to remove the burr B formed on the outer circumferential surface of the pipe P.

In addition, the brush 21b is preferably made of a material such as a brush, not using an iron brush.

In addition, the drive motor 22 and the brush member 21 is connected to the belt is capable of power transmission, and any type of power transmission, such as a sprocket, gear, etc. will be possible.

In addition, the pipe P passing through the through hole 21a of the brush member 21 removes the burrs B formed at both ends in the process of passing from one end to the other end.

In addition, reference numeral 30 denotes a cutter for cutting a pipe.

Referring to the operation according to the present invention in detail as follows.

Continuously supplied iron sheet strip to form a circular pipe (P) in the tube, weld the both ends of the formed steel sheet strip, remove the beads, cut to a certain length.

When cutting the pipe (P) to a predetermined length as described above, the burr (B) and the chip (C) is generated in the cut surface, it is automatically removed on the transfer line of the pipe (P).

When the first cut pipe (P) is transferred along the transfer line, the suction nozzle (11) is positioned at the end of the pipe (P) while the front and rear cylinders (13) are retracted, and at this time, the air compressor (14) Compressed air is discharged to the discharge port of the suction nozzle 11 to discharge the chip (C) accumulated in the inside of the pipe (P) to the discharge port by the strong suction force generated in the suction nozzle (11).

The suction nozzle 11 from which the chip C is discharged is spaced apart from the end of the pipe P while arcing by the support frame 12 when the forward and backward cylinders 13 move forward.

In the state in which the suction nozzle 11 is spaced apart from the end of the pipe P, the pipe P is transported in the transfer line and positioned in the through hole 21a of the brush member 21, and at the same time, the driving motor 22 rotates. When the brush member 21 is rotated, the burr B generated in the cutting process at one end of the pipe P is removed by the brush 21b formed at one side.

In addition, the pipe P from which the burr B at one end is removed passes through the passage hole 21a of the brush member 21, and the burr B at the other end is also removed by the brush 21.

Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, it will be understood that various modifications and other embodiments are possible to those skilled in the art.

In the burr suction device of the pipe according to the present invention as described in detail above, the chip generated in the cutting process of the pipe is sucked in the suction nozzle, the burr formed at the end of the pipe to be processed in the brush member burr generated on the cutting surface of the pipe Will be automatically removed from the workline.
