[0002] Nonferrous metal pipes refer to those metal pipes that do not contain iron or have very low iron content. They are a type of metal pipes, mainly copper pipes, brass pipes, lead pipes, aluminum pipes, and titanium pipes. They usually have good electrical and thermal conductivity and are widely used in various fields. When nonferrous metal pipes need to be connected, repaired, or made into specific structures, they need to be welded. When nonferrous metal pipes are welded, due to their special materials, oxidation easily occurs at the weld, affecting the welding quality. Generally, protective tooling is used to inject argon gas into the pipe body to protect the welding gap.

[0003] However, when welding nonferrous metal pipes, the whole pipe is usually filled with argon for protection, which causes a large amount of argon waste; and the existing welding protection tooling cannot support and protect the welding point, and the weld of the nonferrous metal pipe is prone to deformation, affecting the welding quality of the pipe body.

[0004] Therefore, it is necessary to invent a nonferrous metal pipeline welding protection tool to solve the above problems. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-4 A non-ferrous metal pipeline welding protection tooling shown in the figure comprises two baffles 1 arranged in parallel, and a support plate 2 is installed on the adjacent side of the two baffles 1, wherein an adjustment component 3 is arranged on the inner wall of any one of the baffles 1, and the adjustment component 3 comprises a first ring plate 31 connected to the inner wall of the baffle 1, an electric telescopic rod 32 connected to the inner wall of the baffle 1 and arranged inside the first ring plate 31, and a second ring plate 33 connected to the inner wall of the other baffle 1 and with the end inserted into the first ring plate 31, which is used to adjust the distance between the two support plates 2 to support and protect the welding part of the non-ferrous metal pipe;

[0029] It also includes a push rod 4 installed on the outer wall of any one of the baffles 1, an air inlet pipe 5 installed on the outer wall of the baffle 1 and located above the push rod 4, which is used to fill argon between the two baffles 1, and an exhaust pipe 6 installed on the outer wall of the baffle 1 and located below the push rod 4, which is used to exhaust the air between the two baffles 1 and perform welding protection on the welding points of the non-ferrous metal pipes.

[0030] In one embodiment, the support plate 2 is configured to be annular, the baffle 1 is configured to be circular, and the outer diameter of the baffle 1 is equal to the outer diameter of the support plate 2, which can provide support and protection inside the non-ferrous metal tube and ensure the welding quality of the non-ferrous metal tube. The outer rings of the two baffles 1 are both embedded with a first sealing gasket 7, which improves the sealing between the baffle 1 and the inner wall of the non-ferrous metal tube and reduces the leakage of argon gas between the baffle 1 and the inner wall of the non-ferrous metal tube.

[0031] In one embodiment, the two baffles 1 are connected by an electric telescopic rod 32, and a side wall of the first ring plate 31 is provided with a clearance groove 34 for the second ring plate 33 to be inserted. When the two support plates 2 are close to or away from each other, the second ring plate 33 is always in the clearance groove 34, that is, the second ring plate 33 always slides inside the first ring plate 31, so that the spacing adjustment between the two baffles 1 has high stability, and the two support plates 2 are also relatively stable when adjusting the spacing. The first ring plate 31 is located in the clearance groove 34. A second sealing gasket 35 is embedded in the opening to prevent excessive argon from entering the first ring plate 31 and the second ring plate 33 through the give way groove 34, thereby reducing the amount of argon charged into the outside of the first ring plate 31 and the second ring plate 33. The inner diameter of the intake pipe 5 is larger than the inner diameter of the exhaust pipe 6, so that the amount of argon entering is larger than the amount of gas discharged, and the outside of the first ring plate 31 and the second ring plate 33 can be quickly filled with argon. The baffle 1 for installing the intake pipe 5 and the exhaust pipe 6 is provided with a mounting hole for installing the intake pipe 5 and the exhaust pipe 6.

[0032] In one embodiment, the outer side wall of the baffle 1 on which the air inlet pipe 5 is installed is also connected to a push rod 4, so that the workers can use the welding protection tooling conveniently and quickly insert the welding protection tooling into the weld of the non-ferrous metal pipe.

[0033] The specific implementation method is as follows: when the utility model is in use, the exhaust port of the exhaust pipe 6 is connected to the oxygen concentration detection device for detecting the oxygen concentration at the exhaust pipe 6. Specifically, the staff inserts the welding protection tooling into the non-ferrous metal pipe, and pushes the push rod 4 to make the two baffles 1 slide to the weld between the two sections of non-ferrous metal pipes. At this time, the electric telescopic rod 32 is started, so that the output end of the electric telescopic rod 32 retracts to the left, thereby driving the baffle 1 on the right to slide to the left, so that the support plate 2 on the right gradually approaches the support plate 2 on the left to the left. At this time, the distance between the two support plates 2 is shortened and respectively located on both sides of the weld. At this time, the distance between the two support plates 2 is adapted to the weld, so as to ensure that the weld can be fully in contact with the argon gas, so that the two support plates 2 can provide support and protection for the non-ferrous metal pipe inside the non-ferrous metal pipe, so that the weld of the non-ferrous metal pipe is not easily deformed during welding, thereby ensuring the welding quality of the pipe body in the subsequent sequence;

[0034] Then, argon is filled between the two baffles 1 through the air inlet pipe 5, and there is no need to fill the entire tube with argon, thereby realizing the economical use of argon. The shortened distance between the two baffles 1 further reduces the amount of argon used. With the continuous filling of argon, the air between the two baffles 1 will be discharged through the exhaust pipe 6. At this time, the oxygen concentration detects the oxygen content in the gas discharged from the exhaust pipe 6. When the detected oxygen content is lower than the standard value and does not change much within a period of time, the filling of argon can be stopped, and then welding is performed to complete the welding process of the non-ferrous metal tube.

[0035] This implementation specifically solves the problem in the prior art that, when welding non-ferrous metal pipes, the entire pipe is usually filled with argon for protection, resulting in a large amount of argon waste; and the existing welding protection tooling is unable to support and protect the welding point, the weld of the non-ferrous metal pipe is easily deformed, affecting the welding quality of the pipe body.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
