[0042] The following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are merely for explaining the present utility model and not for limiting it. Additionally, it should be noted that for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0043] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0044] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on the top" of the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under the bottom" of the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0045] In the description of this embodiment, the terms "upper", "lower", "right", and other orientation or positional relationships are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] This embodiment provides a cutting device. As Figure 1 shown, the cutting device includes a cutting machine 100, a bracket 200, and a flame adjustment device. The flame adjustment device is arranged on the bracket 200. The cutting machine 100 is communicated with the flame adjustment device, and the flame adjustment device can move in the horizontal or vertical direction. When the cutting machine 100 moves in the vertical or horizontal direction, it can cut along the cutting line of the workpiece to be cut (steel plate). In the face of steel plates with different thicknesses, it is necessary to adjust the flame temperature of the cutting machine 100 through the flame adjustment device. However, when the flame adjustment device in the prior art adjusts the flame temperature by adjusting the oxygen and gas pressures, it requires frequent manual adjustment by the operator, and the adjustment process is complicated, thus resulting in low production efficiency.

[0047] Therefore, this embodiment also provides a flame adjustment device. As Figures 1 - 6 shown, the flame adjustment device is used to adjust the flame temperature of the cutting machine 100. The flame adjustment device includes a first distribution mechanism 10, a second distribution mechanism 20, a third distribution mechanism 30, and a gas cabinet assembly 40. The first distribution mechanism 10 is used to introduce cutting oxygen into the cutting machine 100; the second distribution mechanism 20 is used to introduce preheating oxygen into the cutting machine 100; the third distribution mechanism 30 is used to introduce gas into the cutting machine 100; the gas cabinet assembly 40 includes a cabinet body 41, and a first control valve group, a second control valve group, and a third control valve group are arranged on the cabinet body 41. The first control valve group, the second control valve group, and the third control valve group are respectively connected to the first distribution mechanism 10, the second distribution mechanism 20, and the third distribution mechanism 30. The first control valve group, the second control valve group, and the third control valve group can respectively adjust the pressures of the cutting oxygen, the preheating oxygen, and the gas to adjust the flame temperature of the cutting machine 100. In the above structure, only by adjusting the first control valve group, the second control valve group, and the third control valve group, the pressures of the cutting oxygen, the preheating oxygen, and the gas can be changed. The operation is simple and convenient, without the need for frequent operations, thus improving the operation efficiency.

[0048] In this embodiment, the oxygen includes two types: cutting oxygen and preheating oxygen. When cutting thin plates with a thickness between 6 mm and 20 mm, the pressure values of the cutting oxygen, preheating oxygen, and fuel gas are 0.8 MPa, 0.6 MPa, and 0.05 MPa for the low-pressure gas path respectively; when cutting medium-thickness steel plates with a thickness between 20 mm and 40 mm, the pressure values of the cutting oxygen, preheating oxygen, and fuel gas are 1.0 MPa, 0.7 MPa, and 0.05 MPa for the medium-pressure gas path respectively; when cutting thick plates with a thickness between 40 mm and 60 mm, the pressure values of the cutting oxygen, preheating oxygen, and fuel gas are 1.2 MPa, 1.0 MPa, and 0.06 MPa for the high-pressure gas path respectively. It should be noted that the above values are reference values in this embodiment. In other embodiments, when cutting steel plates of other thicknesses, adjustments can be made according to actual requirements in accordance with the above reference values.

[0049] Here, it should be noted that in this embodiment, to further reduce the manual workload of the operator, the flame adjustment device is also provided with a computer control system 300. The first control valve group, the second control valve group, and the third control valve group are all communicatively connected to the computer control system 300. That is, through the computer control system 300, the automated control of the cutting oxygen, preheating oxygen, and fuel gas can be realized, thereby ensuring the overall working efficiency and improving the degree of automation.

[0050] As Figures 1 - 4 and Figure 6 shown, the first control valve group includes three cutting valves 42. The first distribution mechanism 10 includes a first control main pipe 11. The first control main pipe 11 is also communicated with three first control branch pipes 12. The three first control branch pipes 12 are respectively connected to the three cutting valves 42 correspondingly. When one cutting valve 42 is opened, the cutting oxygen can enter the first control main pipe 11 through the corresponding first control branch pipe 12, so that the cutting oxygen of different pressures can enter the cutting machine 100 through the first control main pipe 11. In this structure, the three cutting valves 42 respectively control the three first control branch pipes 12, and the three first control branch pipes 12 respectively correspond to the low-pressure, medium-pressure, and high-pressure cutting oxygen in the low-pressure, medium-pressure, and high-pressure gas paths. When cutting steel plates of different thicknesses, only the corresponding cutting valve 42 needs to be adjusted, and the operation is extremely simple and convenient to control. Here, it should be noted that the cutting valve 42 is a pressure reducing valve, which is used to change the pressure of the cutting oxygen in the corresponding first control branch pipe 12.

[0051] Correspondingly, as Figures 1 - 4 and Figure 6As shown, the second control valve group includes three preheating valves 43. The second distribution mechanism 20 includes a second control main pipe 21. The second control main pipe 21 is also connected to three second control branch pipes 22. The three second control branch pipes 22 are respectively connected to the three preheating valves 43 correspondingly. When one preheating valve 43 is opened, the preheated oxygen can pass through the corresponding second control branch pipe 22 to the second control main pipe 21, so that preheated oxygen with different pressures can enter the cutting machine 100 through the second control main pipe 21. In this structure, the three preheating valves 43 respectively control the three second control branch pipes 22, and the three second control branch pipes 22 respectively correspond to the low-pressure, medium-pressure and high-pressure preheated oxygen in the low-pressure, medium-pressure and high-pressure gas paths. When cutting steel plates of different thicknesses is required, only the corresponding preheating valve 43 needs to be adjusted, and the operation is extremely simple and convenient to control. It should be noted here that the preheating valve 43 is a pressure reducing valve, which is used to change the pressure of the cutting oxygen in the corresponding first control branch pipe 12.

[0052] In addition, as Figures 1 - 4 and Figure 6 shown, the third control valve group includes three gas valves 44. The third distribution mechanism 30 includes a third control main pipe 31. The third control main pipe 31 is also connected to three third control branch pipes 32. The three third control branch pipes 32 are respectively connected to the three gas valves 44 correspondingly. When one gas valve 44 is opened, the gas can enter the third control main pipe 31 through the corresponding third control branch pipe 32, so that gases with different pressures can enter the cutting machine 100 through the third control main pipe 31. In this structure, the three gas valves 44 respectively control the three third control branch pipes 32, and the three third control branch pipes 32 respectively correspond to the low-pressure, medium-pressure and high-pressure gases in the low-pressure, medium-pressure and high-pressure gas paths. When cutting steel plates of different thicknesses is required, only the corresponding gas valve 44 needs to be opened, and the operation is extremely simple and convenient to control. It should be noted here that the gas valve 44 is a pressure reducing valve, which is used to change the pressure of the cutting oxygen in the corresponding first control branch pipe 12.

[0053] It should be noted here that as Figure 4 shown, the first control main pipe 11, the second control main pipe 21 and the third control main pipe 31 are all detachably connected to the bracket 200 through a clamp 70. The structure of the clamp 70 is simple, and its shape just fits the arc-shaped outer wall of the pipeline, which is convenient for fixing; secondly, the detachable connection method can also ensure convenient subsequent maintenance and replacement, and is convenient for installation.

[0054] For the convenience of controlling the on-off of each gas flow and the use safety, as Figure 4 and Figure 6As shown in the figure, solenoid valves 50 and check valves 60 are provided on each of the three first control branch pipes 12, the three second control branch pipes 22, and the three third control branch pipes 32. The solenoid valve 50 can control the on-off of the gas in the three first control branch pipes 12, the three second control branch pipes 22, and the three third control branch pipes 32. That is, when one of the low-pressure, medium-pressure, and high-pressure gases needs to be introduced, the corresponding first control branch pipe 12, second control branch pipe 22, and third control branch pipe 32 can be opened, and the operation is simple. At the same time, the check valve 60 can ensure that each gas flow can only flow in one direction, thus ensuring the safety of use.

[0055] To facilitate real-time observation of the pressure value of each gas flow, as Figure 2 、 Figure 3 and Figure 6 shown, three cutting pressure gauges 45, three preheating pressure gauges 46, and three gas pressure gauges 47 are also correspondingly provided on the cabinet body 41. The three cutting pressure gauges 45 can respectively display the pressure of the cutting oxygen passing through the three cutting valves 42, the three preheating pressure gauges 46 can respectively display the pressure of the preheating oxygen passing through the three preheating valves 43, and the three gas pressure gauges 47 can respectively display the gas pressure passing through the three gas valves 44. By setting the cutting pressure gauges 45, the preheating pressure gauges 46, and the gas pressure gauges 47, the real-time pressure of the gas corresponding to each pipeline can be intuitively observed, so as to facilitate adjusting the pressure reducing valve according to the real-time pressure, and then controlling the gas pressure within the preset pressure to ensure the convenience of use.

[0056] To simplify the overall structure, as Figure 3 shown, the first distribution mechanism 10, the second distribution mechanism 20, and the third distribution mechanism 30 respectively include a first distribution main pipe 13, a second distribution main pipe 23, and a third distribution main pipe 33. The first distribution main pipe 13, the second distribution main pipe 23, and the third distribution main pipe 33 are respectively connected to three first distribution branch pipes 14, three second distribution branch pipes 24, and three third distribution branch pipes 34. The three first distribution branch pipes 14, the three second distribution branch pipes 24, and the three third distribution branch pipes 34 are also respectively connected to the three first control branch pipes 12, the three second control branch pipes 22, and the three third control branch pipes 32 correspondingly. The first distribution main pipe 13, the second distribution main pipe 23, and the third distribution main pipe 33 are respectively connected to the cutting gas source, the preheating gas source, and the gas source. This structure is a "four-way structure" (the main pipe intakes gas, and three branch pipes discharge gas), which can simplify the connection structure of the device, without connecting three branch pipes to the cutting gas source, the preheating gas source, and the gas source respectively, thus reducing the overall manufacturing cost.

[0057] As Figure 2As shown, the first distribution main pipe 13, the second distribution main pipe 23, and the third distribution main pipe 33 are all detachably connected to the cabinet body 41 through the clamp 70. The structure of the clamp 70 is simple, and its shape just fits the arc-shaped outer wall of the pipeline, which is convenient for fixing. Secondly, the detachable connection method can also ensure convenient subsequent maintenance and replacement, and is convenient for installation.

[0058] To further improve work efficiency, as Figure 1 , Figure 5 and Figure 6 shown, the first distribution mechanism 10, the second distribution mechanism 20, and the third distribution mechanism 30 respectively include a first distribution pipe 15, a second distribution pipe 25, and a third distribution pipe 35. The first control main pipe 11, the second control main pipe 21, and the third control main pipe 31 are respectively connected and communicated to the first distribution pipe 15, the second distribution pipe 25, and the third distribution pipe 35. A plurality of first distribution sub-pipes 16, a plurality of second distribution sub-pipes 26, and a plurality of third distribution sub-pipes 36 are respectively connected and communicated to the first distribution pipe 15, the second distribution pipe 25, and the third distribution pipe 35. The plurality of first distribution sub-pipes 16, the plurality of second distribution sub-pipes 26, and the plurality of third distribution sub-pipes 36 are correspondingly connected to a plurality of cutting machines 100.

[0059] Since one cutting machine 100 is connected with a stream of cutting oxygen, a stream of preheating oxygen, and a stream of fuel gas, and in the above setting, since the first distribution pipe 15 is connected to the first control main pipe 11, when the cutting oxygen enters the first distribution pipe 15, it will flow into the plurality of first distribution sub-pipes 16 respectively, and flow to the plurality of cutting machines 100 through the plurality of first distribution sub-pipes 16. Similarly, when the preheating oxygen enters the second distribution pipe 25, it will flow into the plurality of second distribution sub-pipes 26 respectively, and flow to the plurality of cutting machines 100 through the plurality of second distribution sub-pipes 26. Similarly, when the fuel gas enters the third distribution pipe 35, it will flow into the plurality of third distribution sub-pipes 36, and flow to the plurality of cutting machines 100 through the plurality of third distribution sub-pipes 36. This setting can supply gas to a plurality of cutting machines 100 at the same time, thereby improving work efficiency.

[0060] It should be noted here that as Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, a total of 16 first distribution sub-pipes 16, 16 second distribution sub-pipes 26, and 16 third distribution sub-pipes 36 are provided, and are correspondingly connected to 16 cutting machines 100, so as to ensure that 16 cutting machines 100 can be driven simultaneously. In other embodiments, the set number can be adjusted according to actual needs, and no specific quantity limitation is made in this example. In addition, the first distribution pipe 15, the second distribution pipe 25, and the third distribution pipe 35 are all detachably connected to the bracket 200 through clamps 70. The structure of the clamp 70 is simple, and its outer shape just fits the arc-shaped outer wall of the pipeline, which is convenient for fixing; secondly, the detachable connection method can also ensure convenient subsequent maintenance and replacement, and is convenient for installation.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
