Description

Technical Field

[0001] This utility model relates to the field of conductive nozzle technology, and in particular to a welding gun conductive nozzle with self-cleaning function. Background Technology

[0002] The contact tip is a key consumable component in welding equipment that guides the welding wire and transmits current. It is made of conductive alloy materials such as chromium zirconium copper, copper, and brass. Currently, spatter is generated during the welding process, and it inevitably splashes onto the surface of the contact tip. When the spatter covers the surface of the contact tip, it forms a high-resistivity layer between the contact tip and the welding torch body, which leads to a sharp increase in contact resistance. This affects the normal use of the contact tip. Therefore, those skilled in the art have proposed a welding torch contact tip with a self-cleaning function. Utility Model Content

[0003] Therefore, it is necessary to provide a welding torch contact tip with a self-cleaning function to address the problem of spatter covering the contact tip surface during welding and affecting its use.

[0004] A welding torch contact tip with self-cleaning function, comprising: A conductive nozzle body, wherein one end of the conductive nozzle body is provided with an integrally formed connecting section; A cleaning structure is disposed on the surface of the conductive nozzle body, and the cleaning structure is used for cleaning the surface of the conductive nozzle body; The cleaning structure includes a rotating ring rotatably connected to the surface of the conductive nozzle body. A connector is fixedly connected to one side of the rotating ring, and a connecting rod for cleaning the surface of the conductive nozzle body is fixedly connected to the other end of the connector.

[0005] In one embodiment, a mounting ring is rotatably connected to the surface of the conductive nozzle body, and an integrally formed edge is fixedly connected to the side of the mounting ring near the rotating ring. A rotating ring is fixedly connected to the surface of the rotating ring and slidably connected to the inner side of the mounting ring, and the side of the rotating ring near the rotating ring is in contact with the surface of the mounting ring.

[0006] In one embodiment, a drive cavity is formed between the outer side of the rotating ring and the inner side of the mounting ring, and drive blades arranged in a ring and located inside the drive cavity are fixedly connected to the surface of the rotating ring.

[0007] In one embodiment, the rotating ring has a flow channel inside and an air intake channel connected to the flow channel on the outside.

[0008] In one embodiment, the surface of the connector is provided with an air inlet that communicates with the flow channel, and the interior of the connecting rod is provided with a connecting channel that communicates with the air inlet.

[0009] In one embodiment, a scraper is fixedly connected to the surface of the connecting rod, and the side of the connecting rod with the scraper fixedly connected has evenly distributed exhaust holes that communicate with the connecting channel.

[0010] In one embodiment, the surface along the edge is fixedly connected to an installation tube communicating with the drive cavity, and the surface of the installation tube is connected to a conveying tube.

[0011] Beneficial effects The aforementioned self-cleaning welding torch contact tip can clean the surface of the contact tip during the welding process, reducing the coverage of spatter and preventing the formation of a high-resistance layer on the contact tip surface that would affect its normal use. During the welding process, a cleaning structure is set up, and the rotating ring drives the connector head and connecting rod to rotate, thereby achieving the effect of cleaning the surface of the contact tip body.

[0012] The cleaning operation is driven by the input of protective gas. During the cleaning process, the input protective gas can be discharged through the air inlet, flow channel, connection channel and exhaust port. The cleaning residue can be blown away from the surface of the conductive nozzle body. Since the exhaust port discharges protective gas, it will not affect the effect of the protective gas on welding during normal welding process, and avoid the influence of mixed gas on the effectiveness of the protective gas.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The following is combined with Figures 1-5 This invention describes a welding torch conductive tip with a self-cleaning function.

[0018] In one embodiment, a welding torch contact tip with a self-cleaning function includes: The conductive nozzle body 100 has an integrally formed connecting section 101 at one end. A cleaning structure 200 is disposed on the surface of the conductive nozzle body 100 and is used for cleaning the surface of the conductive nozzle body 100. The cleaning structure 200 includes a rotating ring 202 rotatably connected to the surface of the conductive nozzle body 100. A connector 207 is fixedly connected to one side of the rotating ring 202, and a connecting rod 208 for cleaning the surface of the conductive nozzle body 100 is fixedly connected to the other end of the connector 207.

[0019] The rotation of the rotating ring 202 can drive the connecting rod 208 to rotate, thereby cleaning the surface of the conductive nozzle body 100 and reducing the amount of splatter that adheres to the surface of the conductive nozzle body 100 and affects its conductivity.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, a mounting ring 201 is rotatably connected to the surface of the conductive nozzle body 100. An integrally formed edge is fixedly connected to the side of the mounting ring 201 near the rotating ring 202. A rotating ring 203 is fixedly connected to the surface of the rotating ring 202 and slidably connected to the inner side of the mounting ring 201. The side of the rotating ring 202 near the rotating ring 203 is in contact with the surface of the mounting ring 201.

[0021] A drive cavity is formed between the outer side of the rotating ring 203 and the inner side of the mounting ring 201. Drive blades 204, which are distributed in a ring and located inside the drive cavity, are fixedly connected to the surface of the rotating ring 203.

[0022] An installation tube 205, which communicates with the drive cavity, is fixedly connected to the surface along the edge, and a delivery tube 206 is connected to the surface of the installation tube 205.

[0023] Protective gas is introduced into the drive cavity through the installation pipe 205 via the delivery pipe 206. The input of protective gas drives the drive blade 204 to rotate, thereby driving the rotating ring 203 to rotate. During this process, the rotating ring 203 drives the rotating ring 202 to rotate synchronously, thereby driving the connecting rod 208 to clean the surface of the conductive nozzle body 100, reducing the impact of splashes on conductivity.

[0024] In this embodiment, the rotating ring 202 is located outside the conductive nozzle body 100, so that it will not affect the feeding of the internal welding wire during rotation.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, the inside of the rotating ring 203 is provided with a flow channel 212, and the outside of the rotating ring 203 is provided with an air intake channel 213 that communicates with the flow channel 212.

[0026] The surface of the connector 207 is provided with an air inlet that communicates with the flow channel 212, and the interior of the connecting rod 208 is provided with a connecting channel 209 that communicates with the air inlet.

[0027] A scraper 210 is fixedly connected to the surface of the connecting rod 208, and a vent hole 211 is evenly distributed and connected to the connecting channel 209 on the side of the connecting rod 208 where the scraper 210 is fixedly connected.

[0028] The protective gas that drives the drive blade 204 can be introduced into the interior of the flow channel 212 through the air intake channel 213, and then introduced into the interior of the connecting channel 209 under the action of the air intake hole. Finally, it is discharged through the exhaust hole 211. At the same time, during the rotation of the connecting rod 208, it can drive the scraper 210 to clean the surface of the conductive nozzle body 100, improving the cleaning effect on its surface. Meanwhile, the protective gas discharged from the exhaust hole 211 can blow the cleaning residue away from the surface of the conductive nozzle body 100, avoiding secondary covering. In this embodiment, since the exhaust port 211 discharges protective gas, it will not affect the role of the protective gas in welding during normal welding process, thus avoiding the influence of doped gas on the effectiveness of the protective gas.

[0029] Working principle: During use, protective gas is introduced into the drive chamber through the delivery pipe 206 and the installation pipe 205. Under the action of the drive blade 204, the rotating ring 203 and the rotating ring 202 can rotate synchronously. During this process, the surface of the conductive nozzle body 100 can be cleaned by the connector 207, the connecting rod 208 and the scraper 210. At the same time, the input protective gas is discharged in conjunction with the air inlet, the flow channel 212, the connecting channel 209 and the exhaust port 211, which can blow the cleaning residue away from the surface of the conductive nozzle body 100.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
