Description

Technical Field

[0001] The utility model relates to the technical field of welding torches, in particular to an argon arc welding cooling loading device. Background Art

[0002] The argon arc welding technology is based on the principle of ordinary arc welding. By using the protection of argon gas on the metal welding material, a high current is used to melt the welding material into a liquid state on the base material to be welded to form a molten pool, so that the base metal and the welding material achieve metallurgical bonding. Since argon gas is continuously supplied during the high-temperature melting welding, the welding material cannot contact with oxygen in the air, thus preventing the oxidation of the welding material.

[0003] The existing welding torch parts will generate a relatively high temperature, especially the nozzle and the conductive rod of the welding torch, making it difficult to effectively cool the welding torch, resulting in affecting the quality of the later welding work. The welding torch needs to be intermittently stopped for cooling, which affects the welding processing efficiency. Otherwise, when continuously used for a long time, it will damage the service life of the welding, and the cooling temperature of the welding torch is not convenient to monitor. Often, the worker starts to continuously use it before reaching the safe temperature. Summary of the Utility Model

[0004] The utility model aims to solve the above defects and provides an argon arc welding cooling loading device.

[0005] In order to overcome the defects in the background art, the technical solution adopted by the utility model to solve its technical problems is: an argon arc welding cooling loading device, including a housing. An accommodation cavity is opened inside the housing, both ends of which are communicated with the outside. The accommodation cavity is used to load the nozzle and the conductive rod of the welding torch, and the accommodation cavity matches the shapes of the nozzle and the conductive rod. The upper port of the accommodation cavity is used to insert the welding torch, and the lower port is connected to an air extraction mechanism.

[0006] Further improvement includes that guide plates are arranged in a radial distribution in the accommodation cavity, and the center of the guide plates distributed in a radial and quasi shape is inserted into the nozzle.

[0007] Further improvement includes that the housing includes a right housing and a left housing connected to the right housing in a butt joint manner, and the right housing and the left housing are detachably connected.

[0008] Further improvement includes that a temperature sensor for detecting the temperature of the welding torch in the accommodation cavity is arranged on the housing, and the temperature sensor is electrically connected to the air extraction mechanism.

[0009] Further improvement includes that the air extraction mechanism includes a conduit and a vacuum pump, and the vacuum pump is connected to the lower port of the accommodation cavity through the conduit.

[0010] A further improvement includes providing an air inlet passage on the housing that is in communication with the accommodating chamber, wherein the air inlet passage is disposed adjacent to an upper port of the accommodating chamber.

[0011] A further improvement includes providing a fixing member for installation on the housing.

[0012] The beneficial effect of the utility model is that the utility model accelerates the flow of air in the accommodating cavity through the air extraction mechanism, thereby cooling the nozzle and the conductive rod of the welding gun, and the temperature sensor can detect the temperature.

[0017] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The embodiments in the basic utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] According to Figure 1 and Figure 2 As shown, a argon arc welding cooling loading device comprises a shell 3, wherein the shell 3 has a receiving chamber 8 with both ends connected to the outside, wherein the receiving chamber 8 is used to load the nozzle 501 of the welding gun 5 and the conductive rod 502, and the receiving chamber 8 matches the shape of the nozzle 501 and the conductive rod 502, wherein the upper port of the receiving chamber 8 is used to insert the welding gun 5, and the lower port is connected to the exhaust mechanism to accelerate the air flow in the receiving chamber 8, and the nozzle 501 and the conductive rod 502 can be cooled by this design.

[0019] A guide plate 7 is radially distributed in the accommodation cavity 8. The center of the guide plate 7 distributed in a radial and quasi shape is inserted into the nozzle 501. The guide plate 7 guides the nozzle 501 and conducts air. This design enables the nozzle 501 and the conductive rod 502 to be axially arranged in the accommodation cavity 8, and at the same time facilitates the smooth flow of air in the accommodation cavity 8.

[0020] The housing 3 includes a right housing 301 and a left housing 302 connected to the right housing 301 in a butt joint manner. The right housing 301 and the left housing 302 are detachably connected. The right housing 301 and the left housing 302 are spliced with each other to form the housing 3. By adopting this implementation manner, it is convenient to clean the inside of the accommodation cavity 8.

[0021] A temperature sensor 6 for detecting the temperature of the welding torch 5 in the accommodation cavity 8 is provided on the housing 3. The temperature sensor 6 is electrically connected to the air extraction mechanism. Through this design, when the temperature exceeds the set threshold, the air extraction mechanism will be started, so that the air flow in the accommodation cavity 8 accelerates to cool the conductive rod 502 and the nozzle 501. When the conductive rod 502 and the nozzle 501 are cooled below the threshold, the air extraction mechanism stops working, which is convenient for monitoring the temperature of the welding torch 5.

[0022] The air extraction mechanism includes a conduit 1 and a vacuum pump 2. The vacuum pump 2 is connected to the lower port of the accommodation cavity 8 through the conduit 1 for extracting air from the accommodation cavity 8, so that the air flow flowing in the accommodation cavity 8 cools the conductive rod 502 and the nozzle 501 of the welding torch 5.

[0023] An air inlet channel 4 communicating with the accommodation cavity 8 is opened on the housing 3. The air inlet channel 4 is adjacent to the upper port of the accommodation cavity 8. Through this design, the air flow in the accommodation cavity 8 can be increased. Through this design, the cooling of the conductive rod 502 and the nozzle 501 of the welding torch 5 can be accelerated. For further improvement, the air inlet channel 4 is connected to a refrigerator through a pipeline to inject cold air into the accommodation cavity 8, which can greatly improve the cooling speed.

[0024] A fixing member 9 for installation is provided on the housing 3. The housing 3 is installed on the welding machine through the fixing member 9, which is convenient to use and can also cool the welding torch 5, prolonging the service life of the welding torch 5.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
