Description

Technical Field

[0001] The present invention relates to the technical field of metal material processing, and particularly to a flame spraying device for the surface of metal materials. Background Art

[0002] Flame spraying on the surface of metal materials is a highly valuable process technology. It uses specific equipment to heat the spraying material to a molten or semi-molten state with a flame and spray it onto the surface of the metal material at high speed. During this process, operators need to precisely control parameters such as the flame temperature, spraying speed, and material supply to ensure the quality and uniformity of the coating. Flame spraying can form a strong and specific-performance coating on the metal surface, such as improving wear resistance, corrosion resistance, etc. This not only extends the service life of the metal material but also endows it with new functions and characteristics;

[0003] When processing metals, sometimes it is necessary to perform flame spraying work on the surface of metal materials; while the existing flame spraying equipment on the market sometimes leaks fuel after work, which has a certain degree of danger. Summary of the Invention

[0004] To achieve the above object, the present invention is realized by the following technical solutions: A flame spraying device for the surface of a metal material, including a housing, the outer side surface of the housing is fixedly connected with a first support rod, and the end of the first support rod is fixedly connected with a gas tank. By setting the gas tank, the gas required for the combustion flame can be stored, so that there is always fuel when flame spraying the surface of the metal material. The outer side surface of the gas tank is penetrated by an intake pipe, and the outer side surface of the gas tank is penetrated by an atomizer. The air outlet end of the atomizer is fixedly connected with a connecting pipe. The atomizer is a prior art. After being connected to the power supply, the gas or liquid fuel in the inner cavity of the gas tank will be transmitted to the inner cavity of the sealing mechanism through the connecting pipe. The outer side surface of the housing is penetrated by a fixing block, and the inner side surface of the fixing block is fixedly connected with a sealing mechanism. By setting the sealing mechanism, the gas or liquid in the inner cavity of the gas tank can be sealed, so that the fuel required for combustion will only be ejected when spraying is needed, and after the device finishes working, the device is in a sealed state to prevent fuel leakage and pollution. The sealing mechanism includes a limit box, the limit box is fixedly connected to the inner side surface of the fixing block, the inner wall of the limit box is fixedly connected with a sealing pipe, and the end of the connecting pipe away from the atomizer penetrates the sealing pipe. The sealing pipe is provided to be connected to the end of the connecting pipe away from the atomizer, so that the fuel in the inner cavity of the gas tank can enter the inner cavity of the sealing pipe. A barrier ring is fixedly connected to the inner wall of the sealing pipe, and a breathable plate is fixedly connected to the inner wall of the barrier ring. By setting the breathable plate, the fuel in the inner cavity of the gas tank can pass through the breathable plate and enter the inner cavity of the limit box. A flame spraying mechanism is rotatably connected to the inner cavity of the limit box. By setting the flame spraying mechanism, the fuel discharged from the inner cavity of the sealing mechanism can be ignited, and the flame can be made to rotate and spray, so that the flame contacts different surfaces of the metal material, achieving the effect of fully flame spraying the surface of the metal material.

[0005] Preferably, a sealing ring is fixedly connected to the side of the inner wall of the sealing pipe away from the barrier ring, and a sliding column is slidably connected to the inner cavity of the sealing ring. By setting the sealing ring, the friction force with the outer surface of the sliding column can be increased, so that when the sliding column is completely in the inner cavity of the sealing pipe, the opening of the sealing pipe is blocked. The diameter of the middle part of the sliding column is smaller than that of the end part. Therefore, when the middle part of the sliding column is in the inner ring of the sealing ring, the fuel in the inner cavity of the sealing pipe can be discharged.

[0006] Preferably, a sealing plate is fixedly connected to the end of the sliding column close to the breathable plate, and a soft pad is fixedly connected to the outer side surface of the sealing plate. The soft pad is press-fitted with the outer surface of the barrier ring. By setting the soft pad, damage can be prevented when the sealing plate is pressed against the side of the barrier ring. The sealing plate is provided to block the breathable plate.

[0007] Preferably, a spring is sleeved on the outer surface of the sliding column. The end of the spring is fixedly connected to the outer side of the sealing plate. A blocking strip is fixedly connected to the side of the sealing plate close to the air-permeable plate. The blocking strip is frictionally adapted to the inner wall of the air-permeable plate. By providing the spring, elastic potential energy can be generated, so that the sealing plate at the end of the sliding column is always subjected to a squeezing force towards the air-permeable plate.

[0008] Preferably, the number of the blocking strips is several, and several of the blocking strips are evenly distributed, and several of the blocking strips are all frictionally adapted to the inner wall of the air-permeable plate. By providing several blocking strips, when the sealing plate moves towards the air-permeable plate, several blocking strips can block the holes formed on the outer surface of the air-permeable plate, thereby preventing fuel from entering the inner cavity of the sealing pipe.

[0009] Preferably, the flame spraying mechanism includes a rotating plate which is rotatably connected to the inner cavity of the limiting box. A second support rod is fixedly connected to the outer side of the rotating plate. A gear ring is fixedly connected to the end of the second support rod. By providing the rotating plate, when the gear ring rotates, a stable rotation can be generated in the inner cavity of the limiting box.

[0010] Preferably, the flame spraying mechanism further includes a servo motor which penetrates through the outer side of the housing. The output end of the servo motor is fixedly connected to a rotating rod through a coupling. A gear disc is fixedly connected to the end of the rotating rod. The gear disc is meshed with the gear ring. By providing the servo motor, the rotating rod can rotate after being powered on, and then the gear disc can rotate. By providing the gear disc, the gear ring can be driven to rotate together during the rotation process, and then the rotating plate can rotate.

[0011] Preferably, an oil spraying pipe penetrates through the side of the outer surface of the rotating plate. A connecting block is fixedly connected to the outer side of the end of the oil spraying pipe. A spark plug is fixedly connected to the side of the connecting block away from the oil spraying pipe. The oil spraying pipe can rotate during the rotation of the rotating plate and can spray fuel onto the outer surface of the metal material. By providing the spark plug, an electric spark can be generated, so that the fuel sprayed from the oil spraying pipe can be ignited.

[0012] The present invention provides a flame spraying device for the surface of a metal material. It has the following beneficial effects:

[0013] First, for the flame spraying device for the surface of the metal material, by providing the sealing mechanism, the gas or liquid in the inner cavity of the air tank can be sealed, so that the fuel required for combustion will only be ejected when spraying is needed, and after the device finishes working, the device is in a sealed state to prevent fuel leakage and pollution.

[0014] II. The flame spraying device for the surface of the metal material can ignite the fuel discharged from the inner cavity of the sealing mechanism through the setting of the flame spraying mechanism, and make the flame produce a rotating spraying effect, so that the flame contacts different surfaces of the metal material, achieving the effect of full flame spraying on the surface of the metal material.

[0015] III. The flame spraying device for the surface of the metal material can increase the friction force with the outer surface of the sliding column by setting the sealing ring, so that when the sliding column is completely inside the inner cavity of the sealing tube, the opening of the sealing tube is blocked. The diameter of the middle part of the sliding column is smaller than that of the end part. Therefore, when the middle part of the sliding column is inside the inner ring of the sealing ring, the fuel in the inner cavity of the sealing tube can be discharged.

[0016] IV. The flame spraying device for the surface of the metal material can block the holes opened on the outer surface of the air-permeable plate by several blocking strips when the sealing plate moves towards the air-permeable plate, thus preventing the fuel from entering the inner cavity of the sealing tube.

The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0026] The first embodiment is as Figures 1-6As shown in the figure, the present invention provides a technical solution: a flame spraying device for the surface of a metal material, including a housing 1.

By providing the air tank 3, the gas required for the combustion flame can be stored, so that there is always fuel when flame spraying the surface of the metal material. An air inlet pipe 4 penetrates through the outer side surface of the air tank 3, and an atomizer 5 penetrates through the outer side surface of the air tank 3. The air outlet end of the atomizer 5 is fixedly connected to a connecting pipe 6. The atomizer 5 is a prior art. After being connected to the power supply, it will cause the gas or liquid fuel in the inner cavity of the air tank 3 to be transmitted to the inner cavity of the sealing mechanism 8 through the connecting pipe 6. A fixing block 7 penetrates through the outer side surface of the housing 1, and a sealing mechanism 8 is fixedly connected to the inner side surface of the fixing block 7. By providing the sealing mechanism 8, the gas or liquid in the inner cavity of the air tank 3 can be sealed, so that the fuel required for combustion will only be ejected when spraying is needed. After the device finishes working, the device is in a sealed state to prevent fuel leakage and pollution. The sealing mechanism 8 includes a limit box 81, the limit box 81 is fixedly connected to the inner side surface of the fixing block 7, a sealing pipe 82 is fixedly connected to the inner wall of the limit box 81, and the end of the connecting pipe 6 away from the atomizer 5 penetrates through the sealing pipe 82. The sealing pipe 82 can be connected to the end of the connecting pipe 6 away from the atomizer 5, so that the fuel in the inner cavity of the air tank 3 can enter the inner cavity of the sealing pipe 82. A barrier ring 83 is fixedly connected to the inner wall of the sealing pipe 82, and a breathable plate 84 is fixedly connected to the inner wall of the barrier ring 83. By providing the breathable plate 84, the fuel in the inner cavity of the air tank 3 can pass through the breathable plate 84 and enter the inner cavity of the limit box 81. A flame spraying mechanism 9 is rotatably connected to the inner cavity of the limit box 81. By providing the flame spraying mechanism 9, the fuel discharged from the inner cavity of the sealing mechanism 8 can be ignited, and the flame can be made to rotate and spray, so that the flame contacts different surfaces of the metal material, achieving the effect of full flame spraying on the surface of the metal material.

[0027] On the side of the inner wall of the sealing tube 82 away from the barrier ring 83, a sealing ring 85 is fixedly connected. A sliding column 86 is slidably connected to the inner cavity of the sealing ring 85. By providing the sealing ring 85, the frictional force with the outer surface of the sliding column 86 can be increased, so that when the sliding column 86 is completely inside the sealing tube 82, the opening of the sealing tube 82 is blocked. The diameter of the middle part of the sliding column 86 is smaller than that of the end part. Therefore, when the middle part of the sliding column 86 is inside the inner ring of the sealing ring 85, the fuel in the inner cavity of the sealing tube 82 can be discharged. One end of the sliding column 86 close to the air-permeable plate 84 is fixedly connected with a sealing plate 88. A soft pad 89 is fixedly connected to the outer side surface of the sealing plate 88. The soft pad 89 is in extrusion fit with the outer surface of the barrier ring 83. By providing the soft pad 89, damage can be prevented when the sealing plate 88 is squeezed against the side of the barrier ring 83. The sealing plate 88 can block the air-permeable plate 84. A spring 87 is sleeved on the outer surface of the sliding column 86. The end of the spring 87 is fixedly connected to the outer side surface of the sealing plate 88. A blocking strip 810 is fixedly connected to the side of the sealing plate 88 close to the air-permeable plate 84. The blocking strip 810 is in frictional fit with the inner wall of the air-permeable plate 84. By providing the spring 87, elastic potential energy can be generated, so that the sealing plate 88 at the end of the sliding column 86 is always subjected to a squeezing force towards the air-permeable plate 84. The number of the blocking strips 810 is several, and several of the blocking strips 810 are evenly distributed, and several of the blocking strips 810 are all in frictional fit with the inner wall of the air-permeable plate 84. By providing several blocking strips 810, when the sealing plate 88 moves towards the air-permeable plate 84, several blocking strips 810 can block the holes formed on the outer surface of the air-permeable plate 84, so as to prevent fuel from entering the inner cavity of the sealing tube 82. During use, the operator pours the fuel required for combustion into the intake pipe 4 and makes the fuel located in the inner cavity of the air box 3. Then the atomizer 5 is started, so that the fuel in the inner cavity of the air box 3 enters the inner cavity of the sealing tube 82 through the connecting pipe 6. Under the action of air pressure, the sliding column 86 moves, so that the blocking strip 810 is separated from the air-permeable plate 84, and finally the fuel enters the inner cavity of the limit box 81. When the work is finished and the atomizer 5 is turned off, the sliding column 86 rebounds under the influence of the elastic potential energy of the spring 87, so that the blocking strip 810 blocks the air-permeable plate 84, achieving the effect of preventing fuel leakage after the work is finished.

By providing the rotating plate 91, when the gear ring 93 rotates, a stable rotation can be generated in the inner cavity of the limit box 81. The flame spraying mechanism 9 further includes a servo motor 97 which penetrates through the outer side surface of the housing 1. The output end of the servo motor 97 is fixedly connected to a rotating rod 98 through a coupling. A gear disk 99 is fixedly connected to the end of the rotating rod 98, and the gear disk 99 meshes with the gear ring 93. By providing the servo motor 97, the rotating rod 98 can be rotated after the power is connected, and then the gear disk 99 can be rotated. By providing the gear disk 99, the gear ring 93 can be driven to rotate together during the rotation process, and then the rotating plate 91 can be rotated. A fuel injection pipe 94 penetrates through the side of the outer surface of the rotating plate 91. A connecting block 95 is fixedly connected to the outer side surface of the end of the fuel injection pipe 94, and a spark plug 96 is fixedly connected to the side of the connecting block 95 away from the fuel injection pipe 94. The fuel injection pipe 94 can rotate during the rotation of the rotating plate 91 and can spray fuel onto the outer surface of the metal material. By providing the spark plug 96, an electric spark can be generated, so that the fuel ejected from the fuel injection pipe 94 is ignited. During use, the operator connects the servo motor 97 to the power supply and turns on the switch of the servo motor 97, so that the rotating rod 98 drives the gear disk 99 to rotate, and then the gear ring 93 drives the rotating plate 91 and the fuel injection pipe 94 to rotate. Then, the spark plug 96 is ignited, so that the fuel is ignited and flame spraying treatment is carried out on the outer surface of the metal material.

[0029] Working principle: During use, the operator pours the fuel required for combustion into the intake pipe 4 and makes the fuel located in the inner cavity of the air box 3. Then, the atomizer 5 is started, so that the fuel in the inner cavity of the air box 3 enters the inner cavity of the sealing pipe 82 through the connecting pipe 6. Under the action of air pressure, the sliding column 86 moves, so that the blocking strip 810 is separated from the air permeable plate 84, and finally the fuel enters the inner cavity of the limit box 81. When the work is finished and the atomizer 5 is turned off, the sliding column 86 rebounds under the influence of the elastic potential energy of the spring 87, and then the blocking strip 810 blocks the air permeable plate 84, achieving the effect of preventing fuel leakage after the work is finished; the operator connects the servo motor 97 to the power supply and turns on the switch of the servo motor 97, so that the rotating rod 98 drives the gear disk 99 to rotate, and then the gear ring 93 drives the rotating plate 91 and the fuel injection pipe 94 to rotate. Then, the spark plug 96 is ignited, so that the fuel is ignited and flame spraying treatment is carried out on the outer surface of the metal material.
