[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a dual-circulation water-cooled welding torch, such as Figure 1-6 As shown, it includes a welding torch body 1 and a welding torch nozzle 2 installed at the top of the welding torch body 1; The welding torch body 1 has an inlet chamber 3 and an outlet chamber 4 inside. A water tank 5 is provided at the lower end of the welding torch body 1. A water cooling circulation component is provided inside the water tank 5. The outer wall of the welding torch body 1 is wrapped with a water-cooling pipe 6. Both ends of the water-cooling pipe 6 are equipped with a second water-cooling circulation component, which is installed inside the water tank 5. By setting an inlet chamber 3 and an outlet chamber 4 inside the welding torch body 1 to form an internal water-cooling circulation, and simultaneously forming an external water-cooling circulation by wrapping the water-cooling pipe 6 around the outer wall of the welding torch body 1, dual cooling of the welding torch is achieved. This dual circulation design can significantly improve cooling efficiency, quickly remove the large amount of heat generated during the operation of the welding torch, effectively prevent the welding torch from being damaged due to high temperature, extend the service life of the welding torch, and at the same time ensure the stability of the welding process and reduce welding quality problems caused by excessive temperature.

[0019] like Figure 3 As shown, a one-way valve is installed between the water inlet chamber 3 and the water outlet chamber 4 to control the direction of water flow. The one-way valve ensures that the cooling water flows in one direction along a preset path in the internal circulation, avoiding backflow and ensuring the orderliness and stability of the internal water cooling circulation. This allows the cooling water to flow fully through the area that needs to be cooled, improving the cooling effect, while preventing the cooling efficiency from being affected by water flow turbulence, and further ensuring the normal operation of the welding torch.

[0020] like Figure 4As shown, the water-cooled circulation assembly includes an inlet pipe 7, an outlet pipe 8, a water pump 9, and a water-cooling block 10. The inlet chamber 3 is internally connected to the inlet pipe 7, and the outlet chamber 4 is internally connected to the outlet pipe 8. A water pump 9 is installed on the inner wall of the water tank 5, with its end connected to the end of the inlet pipe 7. A water-cooling block 10 is connected to the bottom of the outlet pipe 8, and the lower end of the outlet pipe 8 is inserted into the water tank 5. The inlet pipe 7 and the outlet pipe 8 provide a clear channel for the delivery of cooling water, ensuring smooth flow of cooling water in the internal circulation. The water pump 9 provides power for the internal water cooling circulation, ensuring that the cooling water can flow continuously and stably in the circulation system to meet the cooling requirements. The water-cooling block 10 can cool the cooling water that has absorbed heat and is discharged from the outlet pipe 8, so that the cooled water flows back to the water tank 5, realizing the recycling of cooling water, saving water resources, and ensuring that the cooling water entering the internal circulation always has a good cooling effect.

[0021] like Figure 5 As shown, the water-cooled circulation assembly 2 includes a water pump 2 11 and a water-cooling block 2 12; A second water pump 11 is installed on the inner wall of the water tank 5. The top of the second water pump 11 is connected to one end of the water cooling pipe 6, and the other end of the water cooling pipe 6 is installed inside the water tank 5, with a second water cooling block 12 installed at the end. The second water pump 11 provides power for the external water cooling circulation, driving the cooling water to flow in the water cooling pipe 6 to ensure the normal operation of the external circulation. The second water cooling block 12 can cool the cooling water flowing out from the water cooling pipe 6 that has absorbed the heat from the outer wall of the welding torch body 1, so that the cooling water can re-enter the water tank 5 to participate in the circulation, improving the utilization rate of the cooling water, while ensuring the cooling effect of the external water cooling circulation. In conjunction with the internal circulation, it further improves the overall cooling efficiency.

[0022] like Figure 5 As shown, the water-cooled pipe 6 includes a spiral pipe 13 and a riser pipe 14; A spiral tube 13 is connected to the end of water pump 2 11. The spiral tube 13 is wound around the outer wall of the welding torch body 1. The end of the spiral tube 13 away from water pump 2 11 is connected to a riser 14. The lower end of the riser 14 is inserted into the water tank 5 and installed on the water cooling block 2 12. The spiral tube 13 is wound around the outer wall of the welding torch body 1, which increases the contact area with the welding torch body 1 and can more fully absorb the heat on the surface of the welding torch body 1, thus improving the external cooling effect. The riser 14 provides a convenient channel for cooling water to flow back from the spiral tube 13 to the water tank 5, ensuring the smooth flow of cooling water in the external circulation. This allows the cooling water that has absorbed heat to be delivered to the water cooling block 2 12 in a timely manner for cooling, ensuring the efficient operation of the external water cooling circulation.

[0023] like Figure 6As shown, a protective cover 15 is installed on the outer wall of the welding torch body 1, and the spiral tube 13 is installed inside the protective cover 15. The protective cover 15 is made of stainless steel ventilation mesh, which not only effectively protects the spiral tube 13 from damage caused by collisions, friction or high-temperature spatter from external objects during welding, thus extending the service life of the spiral tube 13 and ensuring the normal operation of the external water cooling cycle; but also, the stainless steel material has good high temperature resistance and corrosion resistance, and can adapt to the harsh environment during welding. At the same time, the structural design of the ventilation mesh is conducive to air circulation, which can help remove the heat from the spiral tube 13 and the area around the welding torch body 1, enhance the heat dissipation effect, reduce the influence of the external environment on the spiral tube 13, and maintain the cooling performance of the spiral tube 13.

[0024] like Figure 6 As shown, a snap-fit ​​plate 16 is installed on the outer wall of the protective cover 15, and a threaded hole 17 is provided on the snap-fit ​​plate 16. The snap-fit ​​plate 16 and the threaded hole 17 provide convenient conditions for fixing the welding gun. By passing bolts or other connecting parts through the threaded hole 17, the welding gun can be firmly installed in the required position to prevent the welding gun from shaking or shifting during the welding process, ensuring the stability and accuracy of the welding operation, thereby improving the welding quality.

[0025] Working principle: In the internal water cooling cycle, the water tank 5 provides storage space for the water source. When the water pump 9 starts, the cooling water in the water tank 5 is drawn out and transported to the water inlet chamber 3 through the water inlet pipe 7. Since a one-way valve is set between the water inlet chamber 3 and the water outlet chamber 4, the cooling water can only flow in one direction, from the water inlet chamber 3 to the water outlet chamber 4. During this process, it absorbs the heat generated by the welding torch body 1 and the welding torch nozzle 2 when they are working. After absorbing the heat, the cooling water is discharged through the water outlet pipe 8 and then enters the water cooling block 10 for cooling. The cooled water flows back to the water tank 5 to complete the internal water cooling cycle. The external water cooling circulation also uses water tank 5 as the water source. After water pump 2 11 starts, it draws out the cooling water in water tank 5 and delivers it to the spiral tube 13 of water cooling pipe 6. The spiral tube 13 is wrapped around the outer wall of welding torch body 1 and is located inside the protective cover 15. It can fully contact the welding torch body 1 and absorb the heat on its surface. The cooling water after absorbing the heat is delivered to water cooling block 2 12 through riser pipe 14. After being cooled by water cooling block 2 12, it flows back to water tank 5 to complete the external water cooling circulation. In addition, the protective cover 15 protects the spiral tube 13, and the snap-fit ​​plate 16 on the outer wall of the protective cover 15 and its threaded hole 17 can be used to fix the welding torch in a suitable position to ensure stable welding work. Through the synergistic effect of internal and external dual circulation, the welding torch can dissipate the large amount of heat generated during operation in a timely and effective manner, ensuring the stability of the welding process and the service life of the welding torch.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
