Description

Technical Field

[0001] This invention relates to the field of flame cutting technology, specifically to a flame cutting device based on a conical nozzle. Background Technology

[0002] Oxyhydrogen flame cutting equipment utilizes the high-temperature combustion reaction of Brownian gas to cut metal materials. A mixture of hydrogen and oxygen in a specific ratio is injected through a nozzle and ignited, forming a high-temperature Brownian flame. This flame can reach temperatures exceeding 3000 degrees Celsius, possessing extremely strong thermal energy that rapidly heats and melts the metal material. The molten metal is then dispersed by an airflow, thus achieving the cutting purpose.

[0003] Hydrogen and oxygen burn rapidly and have a high calorific value, causing localized overheating. Existing flat sealing nozzles are prone to loosening due to thermal expansion and contraction, affecting the flat sealing effect. Existing flame cutting guns require preheating before use. If the nozzle is aimed at the metal sheet during preheating, the starting point and subsequent cut surfaces will not be flat. Aiming at empty areas will result in wasted heat energy. During flame cutting, the flame heats the workpiece locally, generating internal stress that causes displacement of the cut portion. Summary of the Invention

[0004] The purpose of this invention is to provide a flame cutting device based on a conical nozzle to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A flame cutting device based on a conical nozzle includes a base, a gantry, a support device, a cutting device, a transport device, a heat absorption device, and a preheating device. The gantry and the base are slidably connected, the support device and the gantry are fixedly connected, the cutting device and the support device are fixedly connected, the transport device is located on one side of the base, the heat absorption device and the gantry are fixedly connected, and the preheating device and the heat absorption device are connected.

[0007] When cutting metal sheets, the transport device moves the metal sheet to the designated position and is fixedly connected to the support device and the gantry frame. The cutting device is also fixedly connected to the support device. The support device on the gantry frame can adjust the position of the cutting device. The gantry frame slides on the base, driving the cutting device to cut the sheet. The heat absorption device absorbs the heat generated when cutting the metal sheet. The heat absorption device is connected to the preheating device, and the absorbed heat can be converted to preheat the metal sheet to be processed.

[0008] Furthermore, there are two sets of bases, and each set of bases is equipped with a slide rail, with the gantry frame and the slide rail slidably connected.

[0009] By setting slide rails on two sets of bases, the gantry frame is controlled by a dedicated gantry synchronous servo drive, which allows the gantry frame to slide stably on the base, making the cutting process smoother.

[0010] Furthermore, the support device includes support rods, support plates, sliding plates, and cylinders. There are four sets of support rods. One end of each set of support rods is fixedly connected to the gantry frame, and the other end of each set of support rods is fixedly connected to the four corners of the support plate. The support plate is provided with multiple sliding grooves, and the sliding plate is slidably connected to the sliding grooves. The cylinder body is fixedly connected to the sliding plate, and the cylinder output end is fixedly connected to the cutting device.

[0011] The four sets of support rods are fixedly connected at one end to the gantry frame and at the other end to the four corners of the support plate, ensuring that the support plate can stably follow the movement of the gantry frame. A linear motor on the gantry frame can drive the sliding plate to slide horizontally on the support plate. Multiple grooves are set on the support plate to adjust the height of the cutting device. The cutting device is connected to the sliding plate through a cylinder, so that the cutting device can slide horizontally on the support plate along with the sliding plate. The vertical position of the cutting device can be adjusted more precisely through the cylinder.

[0012] Furthermore, the cutting device includes a mounting plate, a fixing block, an oxyhydrogen flame cutting gun, an automatic igniter, and an oxyhydrogen generator. The mounting plate is fixedly connected to the cylinder output end. There are two fixing blocks, which are fixedly connected to the mounting plate. The oxyhydrogen flame cutting gun passes through the two fixing blocks. The oxyhydrogen flame cutting gun and the oxyhydrogen generator are connected by a pipeline. The automatic igniter is fixedly connected to the fixing block. The automatic igniter is equipped with an ignition tube, the ignition tube opening of which faces the nozzle of the oxyhydrogen flame cutting gun. The oxyhydrogen generator is fixedly connected to the gantry frame.

[0013] The oxyhydrogen flame cutting gun is fixedly connected to the cylinder output end via a mounting plate, and two fixing blocks are also fixedly connected to the mounting plate. The oxyhydrogen flame cutting gun passes through the two fixing blocks, allowing it to be vertically fixed and move smoothly with the cylinder and sliding plate. The oxyhydrogen generator uses the principle of water electrolysis to decompose water into hydrogen and oxygen for supply. The oxyhydrogen generator is fixedly connected to the gantry frame, and the oxyhydrogen generator and the oxyhydrogen flame cutting gun are connected by pipelines, which allows for convenient and timely fuel supply. The mixed hydrogen and oxygen, in a specific ratio, are sprayed through the nozzle and ignited by the automatic igniter to form a high-temperature Brownian flame.

[0014] Furthermore, the oxyhydrogen flame cutting gun includes a high-pressure oxygen pipeline, a fire extinguishing gas pipeline, an oxyhydrogen pipeline, and a conical seal. The fire extinguishing gas pipeline and the oxyhydrogen pipeline are arranged on both sides of the high-pressure oxygen pipeline. There are three conical seals, which are used to seal the high-pressure oxygen pipeline, the fire extinguishing gas pipeline, and the oxyhydrogen pipeline, respectively.

[0015] The fire extinguishing gas pipeline and the hydrogen-oxygen pipeline are arranged on both sides of the high-pressure oxygen pipeline to facilitate the mixing of Brown gas and to extinguish Brown flames. The three sealing cones can be used to seal the gas and can also be changed from flat sealing nozzles to cone sealing nozzles. The cone sealing nozzles are equal pressure nozzles, which provide even pressure during use and make the cutting effect more significant.

[0016] Furthermore, there are multiple sets of transport devices located between two sets of bases. Each transport device includes a first motor, a mounting base, a disc, a support base, a transport roller, and a second motor. The body of the first motor is fixedly connected to the mounting base, the output end of the first motor is drivenly connected to the disc, the support base is fixedly connected to the disc, the body of the second motor is fixedly connected to the support base, and the output end of the second motor is drivenly connected to the transport roller.

[0017] By setting up multiple sets of transport devices on the ground, with the second motor body and support base fixedly connected, and the output end of the second motor connected to the transport roller drive, the metal sheet can be moved smoothly on the transport roller, facilitating material loading. To prevent the gantry from colliding with the transport devices when it moves with other devices, the transport devices can be detected by sensors and tilted. When the gantry approaches a set of transport devices, the first motor controls the disc on the mounting base to rotate 90°, and the support base and transport roller rotate accordingly. When the gantry moves away, it resets. This not only avoids collisions with other devices but also prevents damage to the transport roller during cutting.

[0018] Furthermore, the heat absorption device includes a funnel and a connecting rod. The funnel is located directly below the oxyhydrogen flame cutting gun and has a water inlet. The funnel and one end of the connecting rod are fixedly connected, and the other end of the connecting rod is fixedly connected to the gantry frame. The funnel and the preheating device are also fixedly connected.

[0019] The funnel is located directly below the oxyhydrogen flame cutting torch. Before preheating the torch, boiling water is added to the funnel. The funnel has a temperature sensor; when the temperature reaches 90°C, the valve on the bottom pipe opens, allowing boiling water to flow into the preheating device. Simultaneously, water enters through the inlet to maintain a constant water level inside the funnel. When the temperature drops to a specified value, the valve closes, and water intake stops. During preheating, the water in the funnel absorbs heat. Because the funnel is fixedly connected to the gantry via a connecting rod, the movement of the gantry drives the hydrogen... When the oxy-hydrogen flame cutting torch is cutting, the funnel also moves along with it. The funnel is always located directly below the oxy-hydrogen flame cutting torch. During cutting, the high-pressure oxygen and metal combustion release a large amount of heat. At the same time, the high-temperature metal oxide waste residue formed is blown into the funnel by the high-pressure oxygen stream. The water in the funnel absorbs the heat energy. When the temperature reaches 90°C, the valve on the pipe at the bottom of the funnel opens, discharging the waste residue and hot water into the preheating device. At the same time, water enters through the inlet to ensure that the water level in the funnel remains constant. When the temperature drops to the specified value, the valve closes, and the water inlet also stops entering.

[0020] Furthermore, the preheating device is located below the metal plate. The preheating device includes a steam box, a sieve plate, a steam generating and heating element, and a steam pipe. The funnel and the steam box are connected by a pipe. The sieve plate and the steam box are slidably connected. The steam generating and heating element is fixedly connected to the inner wall of the steam box. The steam pipe is connected to the top pipe of the steam box. The steam pipe is arranged in a serpentine manner on the top of the steam box and has multiple steam holes.

[0021] Before the hydrogen-oxygen flame cutting torch is preheated, boiling water enters the steam chamber. The steam inside the chamber is heated to form water vapor. Since water vapor is less dense than air, it rises to the top of the steam chamber and enters the steam pipes. Because the steam pipes have multiple steam holes, the water vapor floats out from the steam holes and onto the metal sheet to preheat it. The serpentine arrangement of the steam pipes ensures more uniform preheating. During cutting, waste residue and hot water enter the steam chamber and first pass through a sieve plate. The sieve plate filters out the waste residue, and the remaining hot water undergoes the evaporation and preheating process described above to preheat the metal sheet to be cut.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0023] The funnel is fixedly connected to the gantry frame via a connecting rod. Therefore, when the gantry frame moves to drive the oxyhydrogen flame cutting torch for cutting, the funnel also moves accordingly. The funnel is always located directly below the oxyhydrogen flame cutting torch. During the preheating and cutting of the oxyhydrogen flame cutting torch, the Brown flame and the metal combustion release a large amount of heat, some of which is absorbed by the water in the funnel. At the same time, the high-temperature metal oxide waste residue formed is blown into the funnel by the high-pressure oxygen flow. The water in the funnel absorbs heat energy. There is a temperature detection inside the funnel. When the temperature reaches 90°C, the valve on the pipe at the bottom of the funnel opens, discharging the waste residue and hot water into the steam box. At the same time, water enters through the inlet to ensure that the water level inside the funnel remains constant. When the temperature drops to the specified value, the valve closes, and the water inlet also stops flowing water. The sieve plate filters the incoming waste residue, and the remaining hot water is heated to form steam by the steam generator heating element on the inner wall of the steam box. The steam enters the steam pipe. Since there are multiple steam holes on the steam pipe, the steam floats out from the steam holes and onto the metal plate, preheating the metal plate to be cut. Due to the serpentine arrangement of the steam pipe, the preheating can be more uniform. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The present invention provides the following technical solution:

[0034] like Figure 1 As shown, a flame cutting device based on a conical nozzle includes a base 1, a gantry 2, a support device 3, a cutting device 4, a transport device 5, a heat absorption device 6, and a preheating device 7. The gantry 2 and the base 1 are slidably connected, the support device 3 and the gantry 2 are fixedly connected, the cutting device 4 and the support device 3 are fixedly connected, the transport device 5 is located on one side of the base 1, the heat absorption device 6 and the gantry 2 are fixedly connected, and the preheating device 7 and the heat absorption device 6 are connected.

[0035] When cutting metal sheets, the transport device 5 moves the metal sheet to the designated position and is fixedly connected to the gantry frame 2 via the support device 3. The cutting device 4 is fixedly connected to the support device 3. The support device 3 on the gantry frame 2 can adjust the position of the cutting device 4. The gantry frame 2 slides on the base 1, driving the cutting device 4 to cut the sheet. The heat energy absorption device 6 absorbs the heat energy generated when cutting the metal sheet. The heat energy absorption device 6 is connected to the preheating device 7, which can convert the absorbed heat energy into preheating of the metal sheet to be processed.

[0036] like Figure 1 As shown, there are two sets of base 1, and slide rails 11 are provided on the two sets of base 1. The gantry frame 2 and the slide rails 11 are slidably connected.

[0037] By setting slide rails 11 on two sets of bases 1, the gantry frame 2 is controlled by a dedicated gantry synchronous servo drive, which allows the gantry frame 2 to slide stably on the base 1, making the cutting process smoother.

[0038] like Figure 3 - Figure 4 As shown, the support device 3 includes support rods 31, support plates 32, sliding plates 33, and cylinders 34. There are four sets of support rods 31. One end of each set of support rods 31 is fixedly connected to the gantry frame 2, and the other end of each set of support rods 31 is fixedly connected to the four corners of the support plate 32. The support plate 32 is provided with multiple sliding grooves 321. The sliding plate 33 is slidably connected to the sliding grooves 321. The cylinder body of the cylinder 34 is fixedly connected to the sliding plate 33, and the output end of the cylinder 34 is fixedly connected to the cutting device 4.

[0039] Four sets of support rods 31 are fixedly connected at one end to the gantry frame 2 and at the other end to the four corners of the support plate 32, ensuring that the support plate 32 can stably follow the movement of the gantry frame 2. A linear motor is provided on the gantry frame 2 to drive the sliding plate 33 to slide horizontally on the support plate 32. Multiple grooves 321 are provided on the support plate 32 to adjust the height of the cutting device 4. The cutting device 4 is connected to the sliding plate 33 through a cylinder 34, so that the cutting device 4 can slide horizontally on the support plate 32 following the sliding plate 33. The vertical position of the cutting device 4 can be adjusted more precisely through the cylinder 34.

[0040] like Figure 3 - Figure 4As shown, the cutting device 4 includes a mounting plate 41, a fixing block 42, an oxyhydrogen flame cutting gun 43, an automatic igniter 44, and an oxyhydrogen generator 45. The mounting plate 41 is fixedly connected to the output end of the cylinder 34. There are two fixing blocks 42, and the two fixing blocks 42 are fixedly connected to the mounting plate 41. The oxyhydrogen flame cutting gun 43 passes through the two fixing blocks 42. The oxyhydrogen flame cutting gun 43 and the oxyhydrogen generator 45 are connected by pipes. The automatic igniter 44 is fixedly connected to the fixing block 42. The automatic igniter 44 is provided with an ignition tube 441, and the opening of the ignition tube 441 faces the nozzle of the oxyhydrogen flame cutting gun 43. The oxyhydrogen generator 45 is fixedly connected to the gantry 2.

[0041] The oxyhydrogen flame cutting gun 43 is fixedly connected to the output end of the cylinder 34 via the mounting plate 41 and the two fixing blocks 42. The oxyhydrogen flame cutting gun 43 passes through the two fixing blocks 42, so that the oxyhydrogen flame cutting gun 43 can be fixed vertically and can move smoothly with the cylinder 34 and the sliding plate 33. The oxyhydrogen generator 45 adopts the principle of water electrolysis to decompose water into hydrogen and oxygen for supply. The oxyhydrogen generator 45 is fixedly connected to the gantry 2 and the oxyhydrogen generator 45 is connected to the oxyhydrogen flame cutting gun 43 by pipeline, which can conveniently and timely supply fuel. The mixed hydrogen and oxygen are sprayed through the nozzle and ignited by the automatic igniter 44 to form a high-temperature Brownian flame.

[0042] like Figure 3 - Figure 5 As shown, the hydrogen-oxygen flame cutting gun 43 includes a high-pressure oxygen pipeline 431, a fire extinguishing gas pipeline 432, a hydrogen-oxygen pipeline 433, and a conical seal 434. The fire extinguishing gas pipeline 432 and the hydrogen-oxygen pipeline 433 are arranged on both sides of the high-pressure oxygen pipeline 431. There are three conical seals 434, which are used to seal the high-pressure oxygen pipeline 431, the fire extinguishing gas pipeline 432, and the hydrogen-oxygen pipeline 433, respectively.

[0043] The fire extinguishing gas 432 pipeline and the hydrogen-oxygen pipeline 433 are arranged on both sides of the high-pressure oxygen pipeline 431 to facilitate the mixing and formation of Brown gas, which also facilitates the extinguishing of Brown flames. The three sealing cones can be set to achieve a sealing effect, and the flat sealing nozzle can be changed to a cone sealing nozzle 434. The cone sealing nozzle 434 is an isobaric nozzle, which provides balanced pressure during use and a more significant cutting effect.

[0044] like Figure 1 - Figure 3As shown, multiple sets of transport devices 5 are arranged on the ground, with the multiple sets of transport devices 5 located between two sets of bases 1. Each transport device 5 includes a first motor 51, a mounting base 52, a disc 53, a support base 54, a transport roller 55, and a second motor 56. The body of the first motor 51 is fixedly connected to the mounting base 52, and the output end of the first motor 51 is drivenly connected to the disc 53. The support base 54 is fixedly connected to the disc 53. The body of the second motor 56 is fixedly connected to the support base 54, and the output end of the second motor 56 is drivenly connected to the transport roller 55.

[0045] By setting up multiple sets of conveying devices 5, the metal sheet can be moved smoothly on the conveying roller 55, which is convenient for feeding. In order to prevent the gantry 2 from colliding with the conveying device 5 when it moves with other devices, the conveying device 5 can be detected by sensors and tilted. When the gantry 2 approaches a set of conveying devices 5, the first motor 51 controls the disc 53 on the mounting base 52 to rotate 90°, and the support base 54 and the conveying roller 55 follow the rotation. When the gantry 2 leaves, it resets. This not only avoids collisions with other devices, but also avoids damage to the conveying roller 55 during cutting.

[0046] like Figure 1-4 As shown, the heat absorption device 6 includes a funnel 61 and a connecting rod 62. The funnel 61 is located directly below the hydrogen-oxygen flame cutting gun 43. The funnel 61 is provided with a water inlet 611. One end of the funnel 61 and the connecting rod 62 are fixedly connected, and the other end of the connecting rod 62 is fixedly connected to the gantry frame 2. The funnel 61 and the preheating device 7 are fixedly connected.

[0047] Funnel 61 is located directly below the oxyhydrogen flame cutting torch 43. Before the oxyhydrogen flame cutting torch 43 preheats, boiling water is added to funnel 61. Funnel 61 has an internal temperature sensor. When the temperature reaches 90℃, the valve on the bottom pipe of funnel 61 opens, and boiling water flows into the preheating device 7. Simultaneously, water enters through inlet 611 to maintain a constant water level inside funnel 61. When the temperature drops to a specified value, the valve closes, and water entry through inlet 611 stops. When the oxyhydrogen flame cutting torch 43 preheats, the water in funnel 61 absorbs heat energy. Because funnel 61 is fixedly connected to gantry 2 via connecting rod 62, gantry 2 moves... When the oxyhydrogen flame cutting torch 43 is used for cutting, the funnel 61 also moves accordingly. The funnel 61 is always located directly below the oxyhydrogen flame cutting torch 43. During cutting, the high-pressure oxygen and metal combustion release a large amount of heat. At the same time, the high-temperature metal oxide waste residue formed is blown into the funnel 61 by the high-pressure oxygen flow. The water in the funnel 61 absorbs heat energy. When the temperature reaches 90°C, the valve on the bottom pipe of the funnel 61 opens, discharging the waste residue and hot water into the preheating device 7. At the same time, water enters through the inlet 611 to ensure that the water level in the funnel 61 remains constant. When the temperature drops to the specified value, the valve closes, and the water inlet 611 also stops entering water.

[0048] like Figure 3 - Figure 6 As shown, the preheating device 7 is located below the metal plate. The preheating device 7 includes a steam box 71, a sieve plate 72, a steam generating and heating element 73, and a steam pipe 74. The funnel 61 is pipe-connected to the steam box 71, the sieve plate 72 is slidably connected to the steam box 71, the steam generating and heating element 73 is fixedly connected to the inner wall of the steam box 71, and the steam pipe 74 is pipe-connected to the top of the steam box 71. The steam pipe 74 is arranged in a serpentine manner on the top of the steam box 71, and multiple steam holes 741 are provided on the steam pipe 74.

[0049] Before the hydrogen-oxygen flame cutting torch 43 preheats, boiling water enters the steam box 71. The steam inside the steam box 71 is heated to form water vapor. Since water vapor is less dense than air, it rises to the top of the steam box 71 and enters the steam pipe 74. Because the steam pipe 74 has multiple steam holes 741, the water vapor floats out from the steam holes 741 and onto the metal sheet to preheat it. Due to the serpentine arrangement of the steam pipe 74, the preheating can be more uniform. During cutting, waste residue and hot water enter the steam box 71 and first pass through the sieve plate 72. The sieve plate 72 filters out the waste residue, and the remaining hot water undergoes the above-mentioned evaporation and preheating process to preheat the metal sheet to be cut.

[0050] Working principle of the invention:

[0051] The metal sheet is transported to the designated position via conveyor roller 55. Before the oxyhydrogen flame cutting torch 43 preheats, boiling water is added to funnel 61. Funnel 61 has a temperature sensor; when the temperature reaches 90℃, the valve on the bottom pipe of funnel 61 opens, and the boiling water flows into steam box 71. Simultaneously, water enters through inlet 611 to maintain a constant water level in funnel 61. When the temperature drops to the designated value, the valve closes, and water entry through inlet 611 stops. The boiling water is then heated by the steam generator 73 on the inner wall of steam box 71 to form water. Steam, being less dense than air, rises to the top of the steam box 71 and enters the steam pipe 74. Since the steam pipe 74 has multiple steam holes 741, the steam escapes from these holes and lands on the metal sheet, preheating it before cutting. The serpentine arrangement of the steam pipe 74 ensures more even preheating. When ready to cut, the nozzle position is first adjusted using the sliding plate 33 and cylinder 34, then the hydrogen-oxygen generator 45 is activated to electrolyze water, generating hydrogen and oxygen, which are then supplied to the hydrogen-oxygen torch through pipes. The oxyhydrogen flame cutting torch 43 is preheated by the mixed Brown gas ignited by the automatic igniter 44. Simultaneously, the water in the funnel 61 absorbs heat energy. Once the desired temperature is reached, the steam preheating of the metal sheet continues. When cutting begins, the gantry 2 slides on the base 1, moving the oxyhydrogen flame cutting torch 43 to perform the cutting. High-pressure oxygen and metal combustion release a large amount of heat, and the resulting high-temperature metal oxide slag is blown into the funnel 61 by the high-pressure oxygen stream. The water in the funnel 61 absorbs heat energy, and when the temperature reaches a certain level... When the temperature reaches 90℃, the valve on the bottom pipe of the funnel 61 is opened, discharging the waste residue and hot water into the steam box 71. At the same time, water enters through the inlet 611 to ensure that the water level in the funnel 61 remains constant. When the temperature drops to the specified value, the valve is closed, and the inlet 611 also stops entering water. The sieve plate 72 filters the incoming waste residue, and the remaining hot water is heated to form steam through the steam generator 73 on the inner wall of the steam box 71. By repeating the above steam preheating operation on the metal sheet, the metal sheet can be preheated before it is cut.
