Description

Technical Field

[0001] This utility model relates to the field of arc spraying technology, and specifically to a heat dissipation structure for an arc spraying unit. Background Technology

[0002] Arc spraying utilizes two continuously fed metal wires as consumable electrodes, generating an electric arc at their ends as a heat source to melt the wires. Compressed air then atomizes the molten metal into microparticles, which are sprayed at high speed onto the workpiece surface to form a coating. Arc spraying mainly includes an arc spray gun, a power supply, a wire feeding mechanism, and a compressed air system. The power supply provides energy to the arc, the wire feeding mechanism ensures that the metal wire is fed evenly and stably, and the compressed air system is responsible for atomizing the molten metal and propelling the microparticles onto the workpiece surface.

[0003] When an arc spray gun is in operation, the electric arc generated between the electrodes releases a large amount of heat, causing the local temperature of the spray gun to rise rapidly. If the heat cannot be dissipated in time, its performance will gradually decline, the insulating material may age and become brittle, losing its insulating properties, and in severe cases, it may even damage the spray gun and prevent it from working properly.

[0004] Existing arc spraying equipment generally suffers from insufficient heat dissipation mechanisms during operation. When the spray gun temperature is too high, the melting state of the sprayed material becomes unstable, leading to uneven coating thickness, surface roughness, and other problems that severely affect coating quality and equipment lifespan. Furthermore, the heat dissipation structure design of some current arc spraying equipment is relatively simple, failing to provide timely and effective cooling based on temperature changes at different stages of the arc spray gun's operation. This limitation makes it difficult for the equipment to maintain stable performance during high-temperature operation, resulting in a significant decrease in spraying efficiency and failure to meet production schedule requirements. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation structure for an arc spraying unit to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A heat dissipation structure for an arc spraying unit includes a housing, an arc spraying gun, a water-cooling component, a socket, an air-cooling component, and a temperature sensor.

[0008] A base compartment is fixedly installed at the bottom of the enclosure. The arc spray gun is located at the top of the enclosure's internal cavity. A water-cooling assembly is located inside the base compartment. The water-cooling assembly is used to cool and dissipate heat from the arc spray gun. A socket is fixedly connected to the top of the enclosure's internal cavity. The arc spray gun is located inside the socket. An air-cooling assembly is located inside the enclosure. The air-cooling assembly includes a motor, connecting rod, fan, "U"-shaped bracket, and collar. One end of the connecting rod is fixedly connected to the motor's output end, and the other end is movably connected to the fan. The "U"-shaped bracket is movably connected to the collar. The fan is movably connected to the collar. A temperature sensor is fixedly installed on the inner wall of the enclosure.

[0009] By adopting the above technical solution, a water-cooling component is installed to dissipate heat when the arc spray gun is operating. A temperature sensor monitors the temperature of the arc spray gun in real time. When the arc spray gun generates more heat, the air-cooling component is activated to dissipate heat from all directions. This dual heat dissipation mechanism not only effectively reduces the temperature of the arc spray gun, but also has the ability to dissipate heat in a timely and effective manner according to the temperature changes of the arc spray gun at different heat stages, extending the service life of the equipment and ensuring the stable operation of arc spraying.

[0010] A further improvement of this utility model's technical solution lies in the following: the water-cooling assembly includes a pump body, a first connecting pipe, a water tank, a second connecting pipe, and a coiled pipe. One end of the pump body is fixedly connected to the first connecting pipe, and the other end is fixedly installed with a delivery pipe. The delivery pipe is connected through to one side of the water tank. The water tank is installed inside the bottom compartment. One end of the second connecting pipe is fixedly connected to the other side of the water tank. One end of the coiled pipe is fixedly connected to the second connecting pipe, and the other end is fixedly connected to the first connecting pipe. The coiled pipe is wound around the inside of the socket frame.

[0011] In this technical solution, the coiled tube is entirely coiled and wound around the inner wall of the socket, and its inner wall is tightly fitted to the outer surface of the arc spray gun. When the coolant flows inside the coiled tube, it can directly cool the arc spray gun, effectively reducing its operating temperature.

[0012] A further improvement of this utility model is that it also includes two positioning frames, which are respectively fixedly connected to both sides of the inner wall of the box. The first connecting pipe and the second connecting pipe are both fixedly installed inside the two positioning frames.

[0013] The above technical solution uses two positioning frames to support and fix the first connecting pipe and the second connecting pipe, ensuring that they are securely installed on the inner wall of the box.

[0014] A further improvement of this utility model is that a protective plate is fixedly installed inside the tank, and a through groove is formed on the surface of the protective plate to connect with the arc spray gun. An inlet pipe is fixedly installed at one end of the top of the water tank.

[0015] In the above technical solution, the protective plate is fixed inside the housing and is mainly used to protect and isolate the water-cooled components, preventing paint splashes generated during the spraying process from contaminating or damaging the water-cooled components.

[0016] A further improvement of this utility model is that it also includes a device housing, which is fixedly installed on one side surface of the box. A "U"-shaped frame is fixedly connected inside the device housing, and the motor is fixedly installed on the "U"-shaped frame.

[0017] In the above technical solution, a U-shaped frame is fixed inside the outer shell of the device, which mainly serves to provide the main support and installation foundation for the air-cooled components.

[0018] A further improvement of this utility model is that a door panel is movably connected to the surface of the box, and a handle is fixedly installed on one side of the door panel.

[0019] Using the above technical solution, operators can easily open and close the door panel by using a handle.

[0020] A further improvement of this utility model is that a top plate is installed on the top of the housing surface, and multiple through holes are opened on the surface of the top plate. A control terminal is installed on the surface of the top plate.

[0021] In the above technical solution, the through holes are used to exhaust hot air when the air-cooled components are operating, thereby improving heat dissipation efficiency. The control terminal is connected to all electrically controlled devices in the device via circuitry.

[0022] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0023] 1. This utility model provides a heat dissipation structure for an arc spraying unit. By setting a water-cooling component, water cooling can be performed when the arc spraying gun generates heat during operation. A temperature sensor monitors the temperature of the arc spraying gun in real time. When the arc spraying gun generates more heat, the air-cooling component is activated to provide all-round air cooling. This dual heat dissipation mechanism can not only effectively reduce the temperature of the arc spraying gun, but also provide timely and effective heat dissipation based on the temperature changes of the arc spraying gun at different heat stages, extending the service life of the equipment and ensuring the stable operation of arc spraying.

[0024] 2. This utility model provides a heat dissipation structure for an arc spraying unit. By setting up a wind-cooling component, the fan can achieve omnidirectional and tilting rotation operation. When the fan is started, it can achieve multi-angle and omnidirectional air blowing for heat dissipation, effectively improving the heat dissipation efficiency of the arc spraying gun. It can not only quickly reduce the temperature of the arc spraying gun, but also ensure the uniformity of heat dissipation effect and avoid the impact of local overheating on equipment performance.

[0033] The present invention will be further described in detail below with reference to embodiments:

[0034] Example 1

[0035] like Figures 1-6 As shown, this utility model provides a heat dissipation structure for an arc spraying unit, including a housing 1, an arc spraying gun 2, a water-cooling component 3, a socket 4, an air-cooling component 5, and a temperature sensor 7.

[0036] A bottom chamber 101 is fixedly installed at the bottom of the housing 1. An arc spray gun 2 is positioned at the top of the inner cavity of the housing 1. A water-cooling assembly 3 is located inside the bottom chamber 101. The water-cooling assembly 3 is used for water cooling and heat dissipation of the arc spray gun 2. A socket bracket 4 is fixedly connected to the top of the inner cavity of the housing 1. The arc spray gun 2 is located inside the socket bracket 4.

[0037] The arc spray gun 2 is used for arc spraying operations. A placement seat is provided at the bottom of the inner cavity of the housing 1, allowing the workpiece to be sprayed to be placed on the surface of the placement seat. Spraying can begin after starting the arc spray gun 2. The bottom chamber 101 provides installation space for the water-cooling assembly 3. Furthermore, a connecting frame 4 is fixedly fitted onto the outer surface of the arc spray gun 2, supporting part of the structure of the water-cooling assembly 3. Through the function of the water-cooling assembly 3, effective water cooling heat dissipation is achieved when the arc spray gun 2 is working, ensuring stable operation of the equipment in high-temperature environments, extending its service life, and improving spraying efficiency.

[0038] The air-cooled assembly 5 is housed inside the enclosure 1. The air-cooled assembly 5 includes a motor 501, a connecting rod 502, a fan 503, a U-shaped bracket 504, and a collar 505. One end of the connecting rod 502 is fixedly connected to the output end of the motor 501, and the other end is movably connected to the fan 503. The U-shaped bracket 504 is movably connected to the collar 505. The fan 503 is movably connected to the collar 505. The temperature sensor 7 is fixedly installed on the inner wall of the enclosure 1.

[0039] The air-cooling component 5 is located at the rear of the arc spray gun 2. After starting the motor 501, its operation drives the connecting rod 502 to rotate, thereby driving the fan 503 to rotate. The "U"-shaped frame 504 is movably connected to the collar 505 via two rotating rods, while the two sides of the fan 503 are movably connected to the collar 505 via two rotating shafts. This structural design allows the fan 503 to achieve omnidirectional tilting rotation, thus achieving comprehensive airflow cooling when the fan 503 is started, effectively improving the heat dissipation efficiency of the arc spray gun 2. In addition, the equipment is equipped with a temperature sensor 7 for real-time monitoring of the temperature of the arc spray gun 2. When the temperature sensor 7 detects that the temperature of the arc spray gun 2 is too high, the system automatically triggers an alarm and promptly activates the water-cooling component 3 and the air-cooling component 5 for heat dissipation.

[0040] In this embodiment, by using the water-cooling component 3, water cooling can be applied to dissipate heat when the arc spray gun 2 is operating, achieving the purpose of circulating heat dissipation. Simultaneously, the temperature sensor 7 can monitor the temperature of the arc spray gun 2 in real time. When the arc spray gun 2 generates more heat, the temperature sensor 7 automatically triggers the system to simultaneously activate the air-cooling component 5, providing all-around airflow cooling to further improve the heat dissipation effect. This dual heat dissipation mechanism not only effectively reduces the temperature of the arc spray gun 2 but also provides timely and effective heat dissipation based on temperature changes at different stages of arc spraying, extending the service life of the equipment and ensuring the stable operation of arc spraying.

[0041] like Figures 1-6As shown, in this embodiment, preferably, the water-cooling assembly 3 includes a pump body 301, a first connecting pipe 302, a water tank 303, a second connecting pipe 304, and a coiled pipe 305. One end of the pump body 301 is fixedly connected to the first connecting pipe 302, and the other end is fixedly fitted with a delivery pipe. The delivery pipe is connected through to one side of the water tank 303. The water tank 303 is installed inside the bottom compartment 101. One end of the second connecting pipe 304 is fixedly connected to the other side of the water tank 303. One end of the coiled pipe 305 is fixedly connected to the second connecting pipe 304, and the other end is fixedly connected to the first connecting pipe 302. The coiled pipe 305 is wound around the inside of the socket frame 4.

[0042] A water tank 303 is installed inside the base compartment 101 and filled with coolant. When the pump 301 is started, it draws coolant from the water tank 303 and delivers it to the coiled tube 305 via a delivery pipe and a first connecting pipe 302. The coiled tube 305 is coiled and wound around the inner wall of the socket 4, with its inner wall tightly fitted to the outer surface of the arc spray gun 2. As the coolant flows within the coiled tube 305, it directly cools the arc spray gun 2, effectively reducing its operating temperature. Subsequently, the coolant continues to be delivered through the second connecting pipe 304 and eventually flows back into the water tank 303, completing one cycle. This continuous circulating water cooling system not only provides significant heat dissipation but also ensures that the arc spray gun 2 maintains a stable operating temperature during long-term operation, thereby improving the equipment's operating efficiency and service life.

[0043] like Figures 1-6 As shown, preferably, it also includes two positioning frames 6, which are fixedly connected to both sides of the inner wall of the housing 1. The first connecting pipe 302 and the second connecting pipe 304 are both fixedly installed inside the two positioning frames 6. The two positioning frames 6 are used to support and fix the first connecting pipe 302 and the second connecting pipe 304, ensuring that they are firmly installed on the inner wall of the housing 1 and preventing them from loosening or shifting during equipment operation.

[0044] like Figures 1-6 As shown, preferably, a protective plate 102 is fixedly installed inside the housing 1, and a through groove is formed on the surface of the protective plate 102 to connect with the arc spray gun 2. A liquid inlet pipe 8 is fixedly installed at one end of the top of the water tank 303. The protective plate 102 is fixed inside the housing 1 and is mainly used to protect and isolate the water-cooled components 3, preventing paint splashes generated during the spraying process from contaminating or damaging the water-cooled components 3. A through groove is formed on the surface of the protective plate 102, and the nozzle of the arc spray gun 2 can be embedded in this through groove to ensure smooth spraying operation.

[0045] like Figures 1-6As shown, preferably, it also includes a device housing 9, which is fixedly installed on one side surface of the housing 1. A U-shaped frame 504 is fixedly connected to the inside of the device housing 9, and a motor 501 is fixedly installed on the U-shaped frame 504. The device housing 9 is fixed to the housing 1, and its interior is connected to the interior of the housing 1. The U-shaped frame 504 is fixed inside the device housing 9, and its main function is to provide the main support and mounting base for the air-cooled assembly 5. The motor 501 is installed on the U-shaped frame 504. After the motor 501 is started, it can drive the fan 503 to rotate in an inclined direction, so that the fan 503 can achieve all-round air blowing and heat dissipation at a specific angle, thereby effectively improving the heat dissipation efficiency of the arc spray gun 2.

[0046] like Figures 1-6 As shown, preferably, a door panel 10 is movably connected to the surface of the housing 1, and a handle is fixedly installed on one side of the door panel 10. By using the handle, the operator can easily open and close the door panel 10. When performing arc spraying operations, closing the door panel 10 can provide protection, preventing splashes, harmful gases, or strong light generated during the spraying process from causing injury to the operator, while also avoiding external interference and ensuring the safety of the spraying operation.

[0047] like Figures 1-6 As shown, preferably, a top plate 11 is installed on the top of the surface of the housing 1, and the surface of the top plate 11 has multiple through holes. A control terminal 12 is installed on the surface of the top plate 11. The multiple through holes on the top plate 11 are used to exhaust hot air when the air-cooling component 5 is operating, thereby improving heat dissipation efficiency. The control terminal 12 is connected to all electrically controlled devices in the device via circuitry, enabling centralized management of the device's operating status and realizing intelligent operation and monitoring.

[0048] The working principle of the heat dissipation structure of this type of arc spraying unit will be explained in detail below.

[0049] like Figures 1-6As shown, during use, the door panel 10 is opened by the handle, the workpiece to be sprayed is placed on the placement seat inside the housing 1, then the door panel 10 is closed and the arc spray gun 2 is started. The arc spray gun 2 generates heat during operation. At this time, the pump body 301 starts simultaneously, transporting the coolant in the water tank 303 to the coiled tube 305 through the first connecting pipe 302. The coiled tube 305 is tightly fitted to the arc spray gun 2. As the coolant flows inside the tube, it provides water cooling for the arc spray gun 2. The cooled coolant then flows back to the water tank 303 through the second connecting pipe 304, completing the circulating water cooling process, thus effectively meeting the heat dissipation requirements of the arc spray gun 2. If the heat generated by the arc spray gun 2 is too high, the temperature sensor 7 will detect the abnormal high temperature signal and transmit the information to the control terminal 12. The control terminal 12 will then start the motor 501. The motor 501 will drive the connecting rod 502 to rotate. With the cooperation of the collar 505 and the "U"-shaped frame 504, the fan 503 can rotate in the tilt direction, thereby providing comprehensive airflow and heat dissipation for the arc spray gun 2 and the coiled tube 305 on the socket 4. This dual heat dissipation mechanism can not only effectively reduce the temperature of the arc spray gun, but also provide timely and effective heat dissipation according to the temperature changes of the arc spray gun at different heat stages, ensuring the stable operation of the arc spraying and extending the service life of the equipment.

[0050] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
