Description

Technical Field

[0001] This utility model relates to the field of welding cooling devices, and in particular to a wear-resistant welding cooling device. Background Technology

[0002] In the fields of engineering machinery, mining equipment, and metallurgical equipment manufacturing, wear-resistant surfacing technology is widely used to repair worn parts or enhance the wear resistance of workpiece surfaces. In traditional surfacing processes, the high temperatures generated during welding (typically reaching 800-1200℃) can easily lead to the expansion of the heat-affected zone of the substrate, causing problems such as workpiece deformation, residual stress concentration, and cracks in the surfacing layer. Therefore, cooling devices are particularly important.

[0003] Existing cooling technologies, whether air cooling or water cooling, have some problems; air cooling efficiency is significantly affected by ambient temperature (efficiency drops by 40% when temperature difference ≤ 50℃), cannot achieve three-dimensional cooling, and has local overheating; while water cooling consumes a lot of water resources, which is wasteful. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant overlay welding cooling device to solve the problems of poor cooling effect, local overheating, and high water consumption in the prior art, which leads to resource waste.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant overlay welding cooling device, comprising a main body component, a blowing component and a suction component, wherein the main body component includes a workbench and a processing table mounted on the workbench, and a clamping block is provided on the outer side of the processing table;

[0006] The blower assembly includes a first mounting platform and a blower fan installed inside the first mounting platform. A water sprayer is provided on one side of the blower fan, and a water inlet is connected to the water sprayer.

[0007] The suction assembly includes a second mounting platform and a suction fan installed inside the second mounting platform, and a suction port is provided on one side of the suction fan.

[0008] Preferably, the blowing assembly and the suction assembly are arranged opposite each other on both sides of the processing table, and are located on the same axis.

[0009] Preferably, the water spraying component includes an annular water pipe and an atomizing nozzle connected to the annular water pipe, and an mounting ring is provided on the annular water pipe.

[0010] Preferably, the annular water pipe is fitted inside the mounting ring, and the mounting ring is fixedly connected inside the first mounting platform.

[0011] Preferably, the water inlet includes a connecting water pipe and a first connector fixedly connected to the connecting water pipe, and a filter screen is provided inside the connecting water pipe, and a second connector is connected to one end of the first connector.

[0012] Preferably, one end of the connecting water pipe is connected to the annular water pipe, and the connecting water pipe is connected to the annular water pipe and the first connector in a connected manner.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a blowing assembly and a suction assembly on both sides of the processing table, and utilizing the blowing and suction fans in the blowing and suction assemblies, an air duct is formed in the middle. The air is blown out from the blowing assembly and drawn in from the suction assembly. At the same time, by using the water inlet, the atomizing nozzle sprays water mist on one side of the blowing fan, allowing the water mist to move along the air duct and cool down the processing table in the path. The combination of air cooling and water cooling can effectively reduce the temperature and prevent overheating. At the same time, since water mist is sprayed, water waste can be effectively reduced.

[0021] The blower assembly 20 includes a first mounting platform 21 and a blower fan 22 installed inside the first mounting platform 21. A water sprayer 23 is provided on one side of the blower fan 22, and a water inlet 24 is connected to the water sprayer 23. The first mounting platform 21 is fixedly connected to the workbench 11. The blower fan 22 is installed inside the first mounting platform 21 and can be disassembled for easy maintenance. The water sprayer 23 is installed on one side of the blower fan 22, and the water inlet 24 is connected to the water sprayer 23. The other end of the water inlet 24 is connected to a water tank to provide a water source.

[0022] The suction assembly 30 includes a second mounting platform 31 and a suction fan 32 installed inside the second mounting platform 31, and a suction port 33 is provided on one side of the suction fan 32; wherein, the blowing assembly 20 and the suction assembly 30 are arranged opposite each other on both sides of the processing table 12, and are located on the same axis. When the blowing fan 22 in the blowing assembly 20 is started, it blows air, while when the suction fan 32 in the suction assembly 30 is started, it draws air, so that an air duct is formed between the blowing assembly 20 and the suction assembly 30.

[0023] The water spraying component 23 includes an annular water pipe 231 and an atomizing nozzle 232 connected to the annular water pipe 231. An installation ring 233 is provided on the annular water pipe 231. The atomizing nozzle 232 is evenly arranged at equal angles on the annular water pipe 231 to ensure that the water mist can be sprayed evenly. At the same time, the annular water pipe 231 is sleeved inside the installation ring 233. The installation ring 233 is fixedly connected inside the first mounting platform 21, and the annular water pipe 231 is installed and fixed by the installation ring 233.

[0024] The water inlet component 24 includes a connecting water pipe 241 and a first connector 242 fixedly connected to the connecting water pipe 241. A filter screen 243 is provided inside the connecting water pipe 241. One end of the first connector 242 is connected to a second connector 244.

When disassembling, the filter screen 243 can be directly removed after the second connector 244 is removed. The filter screen 243 can filter the water source to prevent large impurities from affecting the quality of the water mist.

[0025] The working principle and usage process of this utility model are as follows: During use, the workpiece to be processed is placed on the processing table 12 and clamped and fixed using the clamping block 13. Then, the welding head can be used to perform welding operations on the workpiece on the processing table 12. Simultaneously, during welding, an air duct is formed by the blowing fan 22 and the suction fan 32, which passes through the processing table 12 to cool the weld. At the same time, a water source is provided by the water inlet 24, causing the water flow to be converted into water mist and sprayed out through the annular water pipe 231 and the atomizing nozzle 232. Since the water mist is on one side of the blowing fan 22, it moves along the air duct, utilizing the combination of air cooling and water cooling for heat dissipation. A filter screen 243 is provided in the first connector 242 to filter the water flow, reducing the requirements for the water source in the water tank. Furthermore, the threaded connection between the second connector 244 and the first connector 242 facilitates the disassembly of the second connector 244, allowing for easy removal and cleaning of the filter screen 243.
