On the other hand, since the cut portions 53 may have the same technical characteristics, they will not be described in detail below. The cutting part 53 is supported by the body part 52 through the moving block 52c. The cut portion 53 serves to cut the processed material using the fluids for cutting the processed material. For this purpose, the configuration of the cutting unit 53 may be various. For example, the cutout 53 may include a cutout body 53a extending in the thickness direction and a nozzle 53b mounted below the cutout body 53a. A mixing chamber and an igniter may be provided inside the cutout body 53a. The nozzle 53b may spray fluids downward and form a flame. The cut portion 53 may be a torch. The cutting part 53 may move in the width direction by the moving block 52c.

The supply unit 540 includes a plurality of valves 543, and is connected to the cut unit 53 to supply fluids for cutting the workpiece to the cut unit 53. In this case, the fluids for cutting the treatment may include an oxygen gas and a fuel gas. Here, the fuel gas may be LNG gas.

The supply unit 540 may include a plurality of hoses 541, a plurality of main pipes 542, and a plurality of valves 543. The plurality of hoses 541 are connected to the cutout portion 53, have a fluid passage, and are connected to an oxygen supply hose 541a for supplying oxygen gas to the cutout portion 53, and a cutout portion 53. It may include a passage and may include a fuel supply hose 541b for supplying fuel gas to the cutout 53.

The valves 543 may reduce the high pressure of the fluids supplied from the main pipes 542 to the inlet side of the hoses 541 to the set pressure after supplying pressure to the outlet side of the hoses 541, respectively. The valves 543 may each have a pressure adjustment shaft that can be adjusted in openings. For example, the length can be adjusted by rotating the pressure regulating shafts, and the opening of the valves 543 can be adjusted by adjusting the length of the pressure regulating shafts, and the supply pressure of the fluids is adjusted by adjusting the opening of the valves 543. Can be. For example, as the length of the pressure regulating shafts increases, the opening degree of the valves 543 decreases. In addition, as the length of the pressure regulating shafts decreases, the opening degree of the valves 543 may increase.

On the other hand, the pressure regulating shafts of each valve 543 can be adjusted in length in different ways with respect to the same rotational direction, for example, if one pressure regulating shaft is increased in length by clockwise axial rotation (forward rotation), The other pressure regulating axis can be reduced in length by the rotation of the axis in the clockwise direction. Also, if one pressure regulating axis is reduced in length with respect to the counterclockwise axis rotation (reverse rotation), the other pressure regulating axis may be increased in length with respect to the counterclockwise axis rotation. Thus, when the valves 543 are mechanically interlocked by the driving unit 550, the opening and the closing of each valve 543 may be different.

The drive unit 550 may be connected to the valves 543 so that the valves 543 operate in conjunction with each other. The driving unit 550 may mechanically interlock each valve 543 between the valves 543, and may interlock the operation of the respective valves 543 such that the openings and the openings of the valves 543 are different from each other. In this case, the driving unit 550 and the valve 543 may be gear coupled.

The driver 550 may include an input unit 551, a drive motor 552, and an output unit 553. The input unit 551 may be provided in plural and may be mounted on the pressure adjusting shafts, respectively. The input unit 551 is a gear-shaped first input member 551a mounted on the pressure regulating shaft of the oxygen supply valve 543a and a gear-shaped second mounted on the pressure regulating shaft of the fuel supply valve 543b. It may include an input member 551b. The drive motor 552 may be installed toward the input unit 551 between the valves 543. The output unit 553 is formed in a gear shape and may be mounted to the rotor of the drive motor 552. In addition, the output unit 553 may be structurally coupled to the input units 551. That is, the output unit 553 is connected between at least two of the valves 543 via the input unit 551, and the opening degree of the valves 543 connected thereto can be simultaneously adjusted by driving of the output unit 553. Can be.

For example, when the rotor of the drive motor 522 rotates clockwise, the output unit 553 rotates clockwise in conjunction with this, and at the same time, the input unit 551 rotates. That is, the first input member 551a and the second input member 551b axially rotate in the counterclockwise direction. By this rotation, the pressure regulating axes of each valve 543 are axially rotated in the counterclockwise direction, and the length is adjusted, and the opening degree of each valve 543 is adjusted by this length adjustment.

On the other hand, when the rotor of the drive motor 522 is rotated in the counterclockwise direction, at the same time, the input unit 551 is rotated in the clockwise direction while the output unit 553 is rotated in the counterclockwise direction. When the input unit 551 axially rotates clockwise, at the same time, the pressure regulating axes of each valve 543 are axially rotated clockwise to adjust the length, and the opening degree of each valve 543 is adjusted.

The sensor unit 560a may be disposed toward the cutting unit 53, and may detect a position of the cutting unit 53 and an operating state of the cutting unit 53. For example, the sensor unit 560a may detect the position of the cutting unit 53 with respect to the transport path of the processing and the state of the flame due to the fluids injected from the cutting unit 53. The sensor unit 560a may have various configurations and methods so as to perform the above-described function, and there is no need to specifically limit the same. The sensor unit 560a may be provided in plural and, for example, may be supported by the respective cutting units 53.

The controller 560b may be connected to the driving unit 550 and the sensor unit 560a and may control the driving unit 560 and the cutting unit 53 based on the detection result of the sensor unit 560a. In this case, the controller 560b may store supply pressure information of the fluids according to the progress of the process performed on the transport path of the processed material. The controller 560b may control the widthwise position of the cut portion 53 with respect to the transfer path and control the operation of the driving unit 550 according to the progress of the processing of the workpiece, and differently control the supply pressure of the fluids. . Various configurations and methods may be applied to the controller 560b.

Referring to FIGS. 5 and 6, the valves 543 may include a hollow valve body 5431, which is mounted across the fluid passage of each hose 541, and a plurality of pressure chambers 5433 inside the valve body 5431. And a partition plate 5432 divided into 5434, an opening h formed in the partition plate 5432 so as to communicate the plurality of pressure chambers 5433 and 5434, and a valve body 5431. At least a portion may include a pressure regulating shaft 5535 which is in contact with or overlaps with the opening h and is capable of stretching and length adjusting in the mounted direction.

The plurality of pressure chambers 5433 and 5434 may include an inlet pressure chamber 5342 formed at the inlet side of the valve body 5431 and an outlet pressure chamber 5433 formed at the outlet side of the valve body 5431. Can be. The pressure chambers 5433 and 5434 are divided up and down, and the opening h may be formed at the center of the divider 5432. An inlet side of each hose 541 may be connected to the inlet pressure chamber 5342, and an outlet side of each hose 541 may be connected to the outlet pressure chamber 5433.

The pressure regulating shaft 5535 includes a valve disk 5535a arranged above the opening h in the inlet pressure chamber 5342, a spring 5455b connected to an upper portion of the valve disk 5535a, and a spring 5535b. A diaphragm 5435d and a valve body which connect the bonnet 5535c connected to the upper part of the valve, the valve disc 5535a and the inner wall of the inlet pressure chamber 5342, and divide the inlet pressure chamber 5342 into a plurality of spaces. It may include a stem 5535e penetrating the top of 5431, extending into the inlet pressure chamber 5342, and screwed to the bonnet 5535c.

The bonnet 5535c has a ring shape with a center penetrated therein, and a thread is formed on the inner circumferential surface thereof, and the outer circumferential surface is supported by the cylinder structure provided on the upper portion of the valve body 5431 so as to be liftable. The stem 5535e may have a thread formed on the outer circumferential surface of the lower portion, and a groove may be formed on the outer circumferential surface of the upper portion.

The lower thread of the stem 5535e is screwed to the thread of the inner circumferential surface of the bonnet 5535c, and the lifting and lowering of the bonnet 5535c is controlled by the shaft rotation of the stem 5535e. The stem 5535e is fixed in height by the groove of the upper outer circumferential surface. Seal pads may be attached to the lower surface of the bonnet 5535c, and the bonnet 5535c and the valve disk 5535a may be connected by a spring 5535b. The upper portion of the stem 5535e is exposed to the upper side of the valve body 5431 and the input unit 551 is mounted.

When the input unit 551 axially rotates the stem 5535e at a predetermined angle, the bonnet 5535c is lifted by screwing while being supported in the cylinder structure formed on the upper portion of the valve body 5431, and the spring 5435b is lifted by the screw assembly. The valve disk 5535a connected to the bonnet 5535c is moved up and down to a predetermined height, and the distance to the opening h is adjusted to adjust the opening degree of the valve 543. This is referred to as opening control of the valve 543 by adjusting the length of the pressure regulating shaft 5435. At this time, the shaft rotation angle and the size of the opening degree correspond one to one.

As described above, when the input unit 551 of the drive unit 550 axially rotates the pressure regulating shaft 5535 to adjust its length, the valve disk 5535a is elevated to adjust the degree of overlap with the opening h, The supply pressure of the fluid can be controlled by the degree of overlap. At this time, the pressure regulating shaft 5535 of the oxygen supply valve 543a and the pressure regulating shaft 5535 of the fuel supply valve 543b are different from each other in the manner of screwing of the stem 5535e and the bonnet 5535c. If one is left screwed, the other is right screwed. Thus, when the length of one pressure regulating shaft 5535 increases, the length of the remaining pressure regulating shaft 5535 decreases, and the opening degree of each valve 543 can be controlled to be opposite to each other. That is, each valve 543 of the supply unit 540 operates differently in the same operation of the driving unit 550, and thus the opening degree may be adjusted differently.

On the other hand, the diaphragm (5435d) is raised by the high pressure of the fluid flowing into the inlet pressure chamber (5434), the bonnet (5435c) and the valve disk (5435a) can be raised and lowered the opening degree of the valve (543) can be adjusted. . This is referred to as expansion and contraction of the pressure regulating shaft 5435, and at this time, the degree of decompression of the valve 543 may be determined by the elasticity of the diaphragm 5435d and the spring 5535b.

7 to 10 is an operation of the cutting device according to an embodiment of the present invention. Here, FIG. 7 is an operation diagram of a cutting device waiting to cut a workpiece, FIG. 8 is an operation diagram of a cutting device initiating cutting of a workpiece, and FIGS. 9 and 10 are a cutting device in progress of cutting a workpiece. Is also working. Hereinafter, a cutting method according to an embodiment of the present invention will be described with reference to FIGS. 7 to 10.

The cutting method is a method of cutting a workpiece, the process of providing a treatment on the transfer path, positioning the cut portion on the upper side of the treatment, supplying fluids for cutting the treatment to the cut portion, using a cut portion And a step of adjusting the supply pressure of the fluids according to the progress of cutting the processing material and cutting the processing material.

Provide a treatment on the transfer path. That is, the processed object is provided on the table 51. For example, the cast steel S cast in the continuous casting facility is supplied to the table 51 and provided on the table 51.

The cut part 53 is positioned above the processing object. That is, the traveling body 52a travels in the longitudinal direction on the rail 51b, or the processed object travels in the longitudinal direction by the table 51 to provide the cut portion 53 above the processed object. At this time, the moving blocks 52c are spaced apart from each other in the width direction, but are wider than the width in the width direction of the workpiece, and the position of the cut portion 53 at this time is called a home position.

The fluids for cutting the workpiece are supplied to the cut portion 53. As a result, a flame f1 for cutting air may be formed below the cut part 53.

The processed object is cut using the cutting part 53. In this case, the process of cutting the processed material may be performed in the order of preheating, cutting start, and cutting progress, and in this case, the supply pressure of the fluids is adjusted according to the progress of the cutting process of the processed material. That is, the oxygen gas and the fuel gas are supplied to the cutting part 53 at a predetermined amount of supply pressure during preheating, and the supply pressure of the fuel gas is further increased until the starting point of the cutting after the end of the preheating, and the amount of heat is sufficiently supplied to the processed material. After the start of cutting, the supply pressure of the fuel gas is reduced, and the supply pressure of the oxygen gas is increased to inject a large amount of oxygen so that the cut surface is cleanly formed. This process is described below.

First, the cut portion 530 is moved in the width direction, positioned above the cut start position of the workpiece, and the oxygen gas supply pressure and the fuel gas supply pressure are adjusted to form the preheat flame f2. The cutting start position is preheated using this preheating flame f2.

Thereafter, while the cutting start position of the processed material is preheated, the preheating progress state is detected by the sensor unit 560a. At this time, if it is determined that the preheating of the processed material is sufficiently sensed by sensing the temperature at the cutting start position, the fuel gas supply pressure is increased to further increase the amount of heat of the flame and maintain it until the cutting is started. The flame at this time can be called an initial cutting flame. At this time, the flame has the largest calorific value.

Then, when it is sensed by the sensor unit 560a that the cutting of the processing is started, the supply pressure of the fuel gas is reduced, and the supply pressure of the oxygen gas is greatly increased. That is, after cutting of the processing material such as cast steel S is started, it is better for cutting surface quality control to inject a large amount of oxygen at high pressure than to apply a large amount of heat to the cutting surface. The flame at this time is called a cutting flame f3. Thereafter, the cut portion 53 is moved to the central portion side of the cast steel S to cut the cast steel S in the width direction, and the process ends.

For example, if the fuel gas pressure is low before cutting of the cast steel is started, the amount of heat decreases, making it difficult to start cutting the cast steel. In addition, if the oxygen gas pressure is high until the cutting of the cast is started, there is a difficulty in stabilizing the flame. In addition, when the cutting of the slab is initiated after the cutting of the slab is started, if the fuel gas supply pressure is high, the slab is melted instead of being oxidized and melted to cut the slab, thereby widening the cutting gap and generating burrs. The cut surface is bad. In addition, if the oxygen gas pressure is low at this time, the slab cannot be cut.

Therefore, in the exemplary embodiment, the cutting unit 53 may automatically adjust the state of the flame according to the progress of the process by the driving unit 550. At the initial stage of cutting of the cast steel, the fuel gas supply pressure is increased and the oxygen gas supply pressure is decreased. Further, from the time after the cutting of the cast steel is started, the fuel gas supply pressure is decreased and the oxygen gas supply pressure is increased. At this time, when regulating the supply pressure of the fluids, the valves 543 connected to the cutout 53 are interlocked to control the supply pressures of the fluids, and in detail, physically contact each valve between the valves 543. The driving unit 550 is operated to control the opening and closing of each valve 543 to be different from each other. In this case, the operation of the driving unit 550 may be simultaneously transmitted to the pressure regulating shaft 5535 of each valve 543 by using a gear driving method. Meanwhile, the controller 560b controls the operation of the driving body 52a, the moving block 52c, the sensor unit 560a, and the driving unit 550 during the above processes.

The above embodiment of the present invention is for the description of the present invention, not for the limitation of the present invention. It is to be noted that the configurations and manners disclosed in the above embodiments of the present invention will be modified in various forms by combining or crossing each other, and such modifications can be regarded as the scope of the present invention. That is, the present invention will be implemented in various different forms within the scope of the appended claims and equivalent technical ideas, and various embodiments of the present invention may be made by those skilled in the art to which the present invention pertains. You will understand.
