Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically a cooling device for an argon arc welding machine. Background Technology

[0002] Argon arc welding machines are machines that use argon arc welding, employing a high-pressure breakdown arc initiation method. Argon arc welding, also known as tungsten inert gas welding, refers to a welding method that uses industrial tungsten or active tungsten as a non-consumable electrode and an inert gas (argon) as a protective shield. Argon arc welding uses a high current to melt the welding material into a liquid state on the substrate, forming a molten pool. This achieves a metallurgical bond between the weld metal and the welding material, preventing oxidation in the weld area. Generally, argon arc welding machines require shutdown for cooling during prolonged operation to lower the machine's main unit temperature. Natural cooling is slow, and high temperatures can easily damage the machine's parts.

[0003] Cooling devices typically have openings, allowing dust, hair, and other debris from the outside air to easily enter the argon arc welding machine and adhere to the outside of the electrical components, affecting their normal heat dissipation and potentially causing damage to internal parts.

[0004] Therefore, this utility model provides a cooling device for an argon arc welding machine to solve the above problems. Utility Model Content

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: It includes an argon arc welding machine body, a first handle fixedly installed at the upper end of the argon arc welding machine body, an electrical wire provided at the right end of the argon arc welding machine body, a side plate provided inside the argon arc welding machine body, the side plate being connected to the main unit inside the argon arc welding machine body, a condenser fixedly installed on the front side of the side plate, the condenser being in contact with the main unit, a fan fixedly installed inside the right end of the argon arc welding machine body, the fan being connected to the condenser, a protective cover fixedly installed on the right side of the argon arc welding machine body, the protective cover being connected to the fan, and a sealing component for closing the inside of the protective cover being provided inside.

[0009] As a preferred technical solution of this application, the sealing component includes a movable groove, which is opened inside the right end of the protective cover. A baffle is slidably installed inside the movable groove. A sealing gasket is glued to the right side of the baffle. The sealing gasket is tightly fitted to the right end of the protective cover. Multiple sets of connecting rods are fixedly installed on the right side of the baffle. A spring is sleeved on the right end of each set of connecting rods. A nut is threaded onto the right end of each set of connecting rods.

[0010] As a preferred technical solution of this application, the right side of the protective cover is provided with multiple sets of grooves, and the left ends of the multiple sets of springs are located in the multiple sets of grooves.

[0011] As a preferred technical solution of this application, a plug plate is movably inserted into the right end of the protective cover, a filter screen is fixedly installed in the lower end of the plug plate, multiple sets of ear plates are provided on the upper side of the protective cover, the upper end of the ear plates is located between the multiple sets of plug plates, and a second handle is fixedly installed in the upper end of the plug plate.

[0014] (III) Beneficial Effects

[0015] When the fan is activated and generates suction, the baffle slides to the right within the movable slot under the suction force of the fan, thereby drawing outside air into the condenser for cooling.

[0023] 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.

[0024] This utility model provides a cooling device for an argon arc welding machine, such as... Figure 1-5 As shown, the argon arc welding machine cooling device includes an argon arc welding machine body 1. A first handle 2 is fixedly installed at the upper end of the argon arc welding machine body 1. An electric wire 3 is provided at the right end of the argon arc welding machine body 1. A side plate 4 is provided inside the argon arc welding machine body 1. The side plate 4 is connected to the main unit inside the argon arc welding machine body 1. A condenser 5 is fixedly installed on the front side of the side plate 4. The condenser 5 is in contact with the main unit. A fan 6 is fixedly installed inside the right end of the argon arc welding machine body 1. The fan 6 is connected to the condenser 5. A protective cover 7 is fixedly installed on the right side of the argon arc welding machine body 1. The protective cover 7 is connected to the fan 6. A sealing component for closing the inside of the protective cover 7 is provided inside the protective cover 7.

[0025] When in use, fan 6 is turned on, and fan 6 generates suction. Under the suction of fan 6, the sealing component slides open inside the protective cover 7, allowing outside air to be drawn into the condenser 5 through fan 6, thereby dissipating heat and cooling the main unit inside the argon arc welding machine body 1. Conversely, the sealing component closes and seals the inside of the protective cover 7, thereby preventing outside air from being isolated from the inside of the argon arc welding machine body 1, and thus preventing dust in the outside air from entering the argon arc welding machine body 1.

[0026] The enclosure includes a movable groove 8, which is located inside the right end of the protective cover 7. A baffle 9 is slidably installed inside the movable groove 8. A sealing gasket 10 is glued to the right side of the baffle 9. The sealing gasket 10 is tightly fitted to the right end of the protective cover 7. Multiple sets of connecting rods 11 are fixedly installed on the right side of the baffle 9. A spring 13 is sleeved on the right end of each set of connecting rods 11. A nut 14 is threaded onto the right end of each set of connecting rods 11.

[0027] Under the action of multiple sets of connecting rods 11 and multiple sets of springs 13, the baffle 9 slides to the right in the movable groove 8 to close the inside of the protective cover 7, thereby sealing the protective cover 7 and effectively preventing dust, hair and other debris in the outside air from entering the interior of the argon arc welding machine body 1 through the opening. This avoids debris adhering to the main unit, which would affect the normal heat dissipation of the main unit and thus prevent damage to the main unit inside the argon arc welding machine body 1, extending the service life of the argon arc welding machine body 1.

[0028] Multiple sets of grooves 12 are provided on the right side of the protective cover 7, and the left ends of multiple sets of springs 13 are located in the multiple sets of grooves 12.

[0029] The multiple sets of grooves 12 facilitate the installation of multiple sets of springs 13, and also ensure that the left end of the multiple sets of springs 13 is within the multiple sets of grooves 12, thus preventing the multiple sets of springs 13 from shifting.

[0030] A plug plate 15 is movably inserted into the right end of the protective cover 7. A filter screen 16 is fixedly installed in the lower end of the plug plate 15. Multiple sets of ear plates 17 are provided on the upper side of the protective cover 7. The upper end of the ear plates 17 is located between the multiple sets of plug plates 15. A second handle 18 is fixedly installed in the upper end of the plug plate 15.

[0031] When in use, the operator can manually pull the second handle 18. The second handle 18 causes the insert plate 15 and the filter screen 16 to slide upward inside the right end of the protective cover 7, thereby cleaning the surface of the filter screen 16 on the insert plate 15 and making it easy to replace the new insert plate 15 and filter screen 16.

[0032] The thickness of the filter screen 16 is less than the thickness of the lower end of the insert plate 15, and the filter screen 16 is recessed at the lower end of the insert plate 15.

[0033] Based on the shape of the filter screen 16 located inside the lower end of the insert plate 15, dust adhering to the surface of the filter screen 16 is prevented from being scraped off when the insert plate 15 and the filter screen 16 are pulled out from the protective cover 7.

[0034] The inner diameter of the movable groove 8 is larger than the inner diameter of the right end of the protective cover 7, the diameter of the baffle 9 is larger than the inner diameter of the protective cover 7, and the diameter of the baffle 9 is smaller than the inner diameter of the movable groove 8.

[0035] When the baffle 9 slides to the left in the movable groove 8, the air drawn in from the right end of the protective cover 7 flows through the space between the outer wall of the baffle 9 and the movable groove 8 and enters the condenser 5, ensuring that air can circulate when the baffle 9 slides to the left end of the movable groove 8.

[0036] Working principle: When fan 6 is started, it generates suction. Because baffle 9 and sealing gasket 10 seal the right end of protective cover 7, the suction generated by fan 6 causes baffle 9 to slide to the right within the movable groove 8. After baffle 9 and sealing gasket 10 move away from the movable groove 8 and the protective cover 7, outside air is drawn into condenser 5 from the protective cover 7 under the suction of fan 6. Condenser 5 cools the drawn-in air, thereby dissipating heat and cooling the main unit inside the argon arc welding machine body 1. When fan 6 stops... At this time, under the action of multiple sets of connecting rods 11, multiple sets of springs 13 and multiple sets of nuts 14, the baffle 9 slides to the right and resets in the movable groove 8, thereby closing the inner wall of the right end of the protective cover 7 and sealing the protective cover 7. The bolts connecting the insert plate 15 and the ear plate 17 are removed, and the insert plate 15 and the filter screen 16 can be taken out from the protective cover 7 by pulling upward by holding the second handle 18. The dust adhering to the surface of the filter screen 16 can be scraped off, and the insert plate 15 and the filter screen 16 can be replaced.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
