Description

Pipe Cutting Machine

The present invention relates to a pipe cutting device, and more particularly, to a pipe cutting device that can produce a pipe of the desired length at the same time by continuously cutting the pipe automatically supplied.

Typically, automatically supplied pipes are produced by cutting the desired length at the end of the process. However, the method of producing one pipe in one cut was not suitable for mass production and was not economical.

In order to overcome this disadvantage, conventionally, a method of producing a plurality of pipes at one time by adopting a split evenly cut at the same time supplied to a length of about 200 meters. That is, when the length of the pipe to be supplied is 200 meters and finally produces a pipe of 50 meters in length, three pipes are operated simultaneously to cut the pipe.

However, this conventional method could not adjust the width of the cutter, so that pipes of various lengths could not be produced, and due to the slight difference of each cutter, cutting could not be made at the same time. Therefore, in many cases, defects occur due to the movement of the pipe during cutting.

Therefore, the present invention is devised to solve the above problems, the first object of the present invention is to provide a pipe cutter that can cut the automatically supplied pipe to a desired length.

A second object of the present invention is to provide a pipe cutter which prevents the pipe from moving during cutting by fixing the position of the supplied pipe.

The object of the present invention as described above, at least one piston (69) capable of reciprocating toward the pipe (1) from one end of the fixed cylinder (52);

At least two cutters (58) installed on the elevator beams (64) at predetermined intervals for cutting the pipe (1);

At least two holders 54 installed on the lifting beams 64 at predetermined intervals, one end of which is in close contact with the pipe 1;

A pair of lower rollers 62 installed at the lower side of the cutter 58 and having both ends supported by the holder 54 in close contact with each other in the longitudinal direction, and rotatably supported at both ends thereof; And

It is achieved by a pipe cutting device, characterized in that it comprises a motor device 66 is installed at one end of the lower roller 62 to rotate the lower roller 62.

In addition, a stopper 60 or a limit switch for determining the position of one end of the pipe 1 conveyed in the longitudinal direction is further provided in the region near one end of the lower roller 62.

Moreover, it is more preferable that 2-5 pieces of said cutters 58 are provided, and the said holder 54 is provided between every said cutters 58.

Hereinafter, with reference to the accompanying drawings to describe the embodiment of the present invention in detail.

1 is a schematic overall process diagram installed with a pipe cutting device according to the present invention. The process includes a pipe stacker 10 for loading and supplying pipes, a conveying device 30 for conveying pipes, a guide device 40 for positioning a conveyed pipe, and a cutting device 50 for cutting the conveyed pipes. Consists of Although not shown in FIG. 1, the cutting device 50 is provided with a separate discharge device for discharging the cut pipe.

FIG. 2 is a block diagram of a pipe loader 10 for loading and supplying pipes shown in FIG. 1. As shown in Fig. 2, the loaded pipe 12 is immersed in wire mesh, leather, vinyl, or the like, and is supplied in line along the conveyance belt 16 as it is pulled by the motor. The pipe 14 being transported is prepared to be transported by being positioned by the lower jig 18 and the rotating jig 19 out of the transport belt 16.

3 is a block diagram of the pipe feeder 30 shown in FIG. As shown in FIG. 3, the pipe 14 supplied by the pipe loader 10 is horizontally transferred by the plurality of guide rollers 32. The guide roller 32 is driven by a separate motor device (not shown), some of which are idle rollers. The downstream end of the transfer device 30 is provided with a guide device 40 in which a pair of rollers are arranged up and down. This guide device 40 serves to hold the correct position of the pipe just before entering the cutting device.

4 is a configuration diagram of the pipe cutting device 50 shown in FIG. 1 according to the present invention, FIG. 5 is a side configuration view of the pipe cutting device 50 shown in FIG. 4, and FIG. 6 is a cutter in FIG. 4. (58) An enlarged view of the part.

As shown in Figs. 4, 5, and 6, a pair of hydraulic cylinders 52 are provided at the top and fixed to the housing. The piston 69 of the cylinder 52 can be reciprocated up and down, and a lifting beam 64 is provided at the free end of the piston 69 to move up and down.

The elevator beams 64 are provided with cutters 58 (three in Fig. 4) at positions of required cutting lengths, and holders 54 are provided between the cutters 58, respectively. Although the cutter 58 and the holder 54 are firmly fixed to the elevator beam 64, the cutter 58 and the holder 54 may be horizontally moved to a required position when disassembling a coupling means such as a bolt.

At the lower end of the elevator beams 64, a pair of lower rollers 62 are provided to contact each other. One end of the lower roller 62 is rotatably supported by the bearing 70, and the other end is connected to a motor device 66 in which a speed reducer (not shown) is built.

A stopper 60 is provided on the upper portion of the motor device 66 to stop the supplied pipe 1 at the correct position. This stopper 60 can also be used in place of a limit switch (limit switch).

As shown in FIG. 5, the lifting beam 64 is fixed to one end of the piston 69 reciprocating from the cylinder 52, and the holder 54 is fixed to the lifting beam. The lower end of the holder 54 is provided with a roller 57 that can rotate in close contact with the pipe 1. The roller 57 serves to allow the pipe 1 to rotate while keeping the pipe 1 in close contact with the lower roller 62. The roller 57 may be made of a soft metal such as urethane, aluminum, steel, or the like.

As shown in FIG. 6, a rotatable core 74 is provided at the lower end of the cutter 58, and a cutter blade 72 is formed around the circumference of the core 74 to actually cut the pipe 1. have. The cutter blade 72 can adjust its shape and type according to the diameter, material, cutting speed, etc. of the pipe 1.

In the above, the operation of the pipe cutting device 50 having the above configuration will be described.

A steel (or stainless) pipe 1 of about 200 meters in length and about 1 to 8 centimeters in diameter enters between the pair of lower rollers 62. When the entry is completed and stopped by the stopper 60, the hydraulic pressure is supplied to the cylinder 52 so that the pair of pistons 69 descend simultaneously. Therefore, as the lifting beam 64 descends, the holder 54 makes the outer diameter of the pipe 1 adhere to the lower roller 62. At the same time, the motor device 66 rotates to supply rotational force to either or both of the pair of lower rollers 62.

The lower roller 62 rotates together with the roller 57 of the pipe 1 and the holder 54. At the same time, the cutter blade 72 of the cutter 58 enters the pipe 1 to cut the pipe 1.

When the cutting is completed, the motor device 66 stops and the lifting beam 64 rises. The cut pipe is then discharged to a length of about 60 or 70 meters through a separate discharge device. When the discharge is completed, a new pipe 1 is supplied again for repetitive work, and this process is repeated.

In the present invention, the holder 54 and the cutter 58 to the elevator 64 can be fixed by a bolt or the like. Accordingly, the position of the holder 54 and the cutter 58 can be changed or the number thereof can be changed by using bolts and nuts. However, the present invention is not limited thereto, and any coupling means may be used as long as it can exhibit similar coupling force.

The cylinder of the present invention used a hydraulic cylinder, but can be replaced with a pneumatic cylinder if necessary.

According to the pipe cutting device of the present invention as described above, there is an advantage that can be cut to the desired length of the pipe automatically supplied to mass production. In addition, it is possible to mass-produce a pipe having an accurate length by fixing the position of the supplied pipe to prevent the pipe from moving during cutting.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Therefore, the scope of the utility model registration claims attached will include such modifications or variations that fall within the spirit of the present invention.
