Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to an argon arc welding protection device for processing stainless steel products. Background Technology

[0002] Argon arc welding occupies an important position in the stainless steel processing field due to its characteristics such as inert gas protection, arc stability, and small heat-affected zone, and is widely used, especially in food machinery and chemical equipment. However, existing argon arc welding protection devices for stainless steel product processing still have some problems in use: First, existing argon arc welding protection devices only have argon gas on / off valves and lack flow regulation structures. This can easily lead to waste due to excessive argon gas or affect the protection effect due to insufficient argon gas, thus reducing the device's adjustment flexibility. Secondly, the nozzle guards of existing devices are mostly fixed installations, and it is not possible to flexibly replace guards of different shapes according to welding requirements to optimize the argon gas gathering effect, which limits the flexibility of device use. Utility Model Content

[0014] 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.

[0015] Example: Figure 1-5 As shown, this utility model provides an argon arc welding protection device for stainless steel product processing, including an argon cylinder 1, which provides an argon gas source. A valve 4 is connected to the upper surface of the argon cylinder 1 to control the flow of argon gas. A connecting pipe 5 is connected to one side of the valve 4 to deliver argon gas. An airflow regulating component 2 is provided on both the inside and the outer surface of the connecting pipe 5. A flexible hose 6 is connected to one end of the connecting pipe 5 to facilitate the flexible movement of an argon gas nozzle gun 7. An argon gas nozzle gun 7 is connected to one end of the flexible hose 6. A gas distributor 9 is connected to the output end of the argon gas nozzle gun 7. Multiple air holes 8 are opened on one side of the gas distributor 9 to ensure that argon gas is sprayed out evenly.

[0016] The outer surface of the argon nozzle gun 7 is provided with a protective component 3. The airflow adjustment component 2 and the protective component 3 respectively enhance the flexibility of the device in adjustment and use. The overall structure realizes stable argon supply and protection.

[0017] The airflow regulating component 2 includes a housing 22, which is fixedly installed on the outer surface of the connecting pipe 5. The housing 22 provides an installation base for the airflow regulating component 2. A vertical rod 26 is rotatably connected to the inner wall of the housing 22. The bottom end of the vertical rod 26 passes through the connecting pipe 5 and is fixedly connected to a flow ball 21. The flow ball 21 has a through hole. A sealing ring 27 that works with the vertical rod 26 is fixedly connected to the outer surface of the connecting pipe 5. The vertical rod 26 is rotatably connected to the inner wall of the sealing ring 27. The sealing ring 27 ensures the sealing between the vertical rod 26 and the connecting pipe 5 to prevent argon gas leakage.

[0018] The bottom end of the flow ball 21 is rotatably connected to the inner wall of the connecting pipe 5. A gear 25 is fixedly sleeved on the outer surface of the vertical rod 26. The gears 25 are meshed and connected. The meshing of the gears 25 drives the two flow balls 21 to rotate in tandem, thereby realizing the rapid adjustment of the argon gas flow cross section and controlling the gas flow. A servo motor 24 is fixedly installed on the upper surface of the housing 22. The servo motor 24 can receive control signals through an external controller. According to the preset correspondence between the motor rotation angle and the argon gas flow, it drives the vertical rod 26 to rotate at a specific angle, thereby precisely adjusting the size of the argon gas flow cross section through the flow ball 21 and realizing the quantitative control of the argon gas flow. A cover 23 for use with the servo motor 24 is fixedly installed on the upper surface of the housing 22. The servo motor 24 is fixedly installed inside the cover 23, and the cover 23 protects the servo motor 24.

[0019] Furthermore, the output end of the servo motor 24 passes through the upper surface of the housing 22 and is fixedly connected to the top of one of the vertical rods 26. The servo motor 24 drives the vertical rod 26 to rotate, improving the stability of the component and significantly enhancing the adjustment flexibility of the device.

[0020] The protective component 3 includes a first connecting ring 34, which is fixedly sleeved on the outer surface of the argon nozzle gun 7. A magnetic rod 36 is magnetically inserted into one side of the first connecting ring 34. The magnetic attraction between the first connecting ring 34 and the magnetic rod 36 facilitates the initial positioning of the protective cover 31.

[0021] A positioning block 33 is symmetrically fixedly connected to one side of the first connecting ring 34. A bolt 35 is threadedly connected between the magnetic suction rod 36 and the positioning block 33. The positioning block 33 and the bolt 35 are further fixed to realize the quick disassembly and replacement of the protective cover 31.

[0022] Furthermore, a second connecting ring 32 is fixedly connected to one side of the magnetic suction rod 36, and a protective cover 31 is fixedly connected to one side of the second connecting ring 32. The second connecting ring 32 ensures that the protective cover 31 is installed firmly. The protective cover 31 is a high-temperature resistant cover, specifically made of high-temperature resistant polycarbonate material. The high-temperature resistant protective cover 31 can adapt to the high-temperature welding environment. Different shapes of protective covers 31 can be flexibly replaced according to welding requirements, effectively improving the flexibility of the device.

[0023] Working principle: During argon arc welding, valve 4 at the top of argon cylinder 1 is opened first. The high-pressure argon gas stored in argon cylinder 1 enters the connecting pipe 5 through valve 4. Valve 4 can realize the on-off control of argon gas supply, providing the basic gas source for subsequent gas flow regulation and protection operations.

[0024] After argon gas enters the connecting pipe 5, it flows through the airflow regulating component 2 to achieve flow regulation. The servo motor 24 inside the cover 23 above the housing 22 is started. The output end of the servo motor 24 drives the vertical rod 26 fixedly connected to it to rotate. The meshing action of the gear 25 causes the two vertical rods 26 to drive the corresponding flow balls 21 to rotate in tandem. By changing the relative angle between the flow balls 21, the size of the argon gas flow cross section is adjusted, thereby controlling the argon gas flow rate.

[0025] Meanwhile, the sealing ring 27 on the outer surface of the connecting pipe 5 is rotatably connected to the inner wall of the vertical rod 26 to ensure the sealing of the connecting pipe 5 when the vertical rod 26 rotates, and to prevent argon gas leakage from affecting the adjustment accuracy and protection effect.

[0026] Argon gas, after being regulated by the airflow regulating component 2, is delivered to the argon gas nozzle gun 7 through the hose 6 at one end of the connecting pipe 5. The hose 6 can flexibly adjust the working angle and position of the argon gas nozzle gun 7.

[0027] After argon gas enters the argon gas nozzle gun 7, it is distributed by the gas distribution cylinder 9 connected to its output end. Multiple gas holes 8 on one side of the gas distribution cylinder 9 spray out argon gas evenly, forming an argon gas layer covering the welding area, providing a uniform gas source for weld protection.

[0028] At the same time, the protective component 3 simultaneously protects the welding area: the first connecting ring 34, which is fixedly sleeved on the outer surface of the argon nozzle gun 7, is initially positioned with the magnetic rod 36 by magnetic attraction, and then the magnetic rod 36 is firmly fixed by the threaded connection between the positioning block 33 and the bolt 35.

[0029] The second connecting ring 32 on one side of the magnetic rod 36 drives the protective cover 31 to be stably installed outside the welding area. The high-temperature resistant protective cover 31 can isolate external airflow interference, gather the argon gas sprayed from the gas distribution cylinder 9, and prevent air from entering the welding area and causing the weld to oxidize.

[0030] Meanwhile, different shaped protective covers 31 can be quickly replaced by disassembling bolts 35 and separating magnetic rods 36 according to welding requirements, ensuring protective adaptability.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
