Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0029] like Figures 1-4 As shown, a welding machine for producing non-ferrous metal pipe fittings according to one embodiment of the present invention includes a main body mechanism 1, a clamping mechanism 2, and a cooling and protection mechanism 3. The main body mechanism 1 includes an operating table 11, a welding machine 12, a welding torch head 15, and a storage assembly. The welding machine 12 is mounted on the operating table 11, and the welding machine 12 and the welding torch head 15 are electrically connected. The storage assembly is located at the bottom of the operating table 11. A pair of clamping mechanisms 2 are arranged opposite to each other. Each pair of clamping mechanisms 2 includes a mounting plate 21, a limiting cylinder 22, and an arc-shaped clamping plate 26. The mounting plate 21 is mounted on the operating table 11 in a linear motion manner, and the limiting cylinder 22 is mounted on the mounting plate 21 in a rotatable manner. The arc-shaped clamping plate 26 is installed inside the limiting cylinder 22 in a vertically movable manner. The cooling and protection mechanism 3 includes an annular gas supply pipe 31 installed around the welding torch head 15, and multiple nozzles 32 installed on the bottom side wall of the annular gas supply pipe 31.

[0030] When using this welding machine for producing non-ferrous metal pipe fittings, the linear moving mounting plate 21 drives the limiting cylinder 22 to move, thereby adjusting the distance between the pair of limiting cylinders 22. Then, the two ends of the workpiece are placed in the pair of limiting cylinders 22 respectively, and the workpiece is clamped and fixed by the arc-shaped clamping plate 26. The two ends of the workpiece are limited and fixed by the cooperation of the limiting cylinder 22 and the arc-shaped clamping plate 26. After the workpiece is fixed, the welding machine 12 can weld the workpiece through the welding gun head 15. During welding, the low-temperature inert gas delivered by the annular gas supply pipe 31 is sprayed around the weld seam through multiple nozzles 32. The inert gas forms an air curtain around the weld seam, which isolates the outside air from the weld seam, thereby preventing the weld seam from contacting oxygen during welding and preventing the weld seam from oxidizing. At the same time, the low-temperature nitrogen gas cools the area around the weld seam, preventing welding thermal deformation, thereby improving the welding quality of the workpiece. When welding, if the workpiece needs to be rotated, the limiting cylinder 22 can drive the workpiece to rotate, realizing welding at different positions in the circumference of the workpiece, which improves the welding efficiency and makes the welding of the workpiece more convenient.

[0031] like Figure 3 and Figure 6 As shown, the main body mechanism 1 also includes a mounting frame 13 and a telescopic component 14. The mounting frame 13 is mounted on the welding machine 12, and the telescopic component 14 is mounted on the end of the mounting frame 13 away from the welding machine 12. The welding torch head 15 is mounted on the lower end of the telescopic component 14. The telescopic component 14 is used to adjust the height of the welding torch head 15 so that the height of the welding torch head 15 can be adjusted according to the welding position after the workpiece is fixed. At the same time, there is an electrical connection between the welding machine 12 and the welding torch head 15 so that the welding torch head 15 can weld the workpiece under the action of the welding machine 12.

[0032] like Figures 1-4 As shown, the storage components include a storage box 16, a waste collection box 17, a tool collection box 18, and a slag discharge port 19. The slag discharge port 19 is opened on the workbench 11 in a vertical through manner, and the storage box 16 is fixedly connected to the bottom wall panel of the workbench 11.

[0033] like Figures 1-4 As shown, the waste collection box 17 and the tool collection box 18 are slidably connected to the storage box 16 in an up-down manner, with the waste collection box 17 positioned below the slag discharge port 19. The waste collection box 17 is used to collect welding slag, which enters into the waste collection box 17 through the slag discharge port 19 during welding. The tool collection box 18 is used to store welding rods and other tools.

[0034] like Figure 4 and Figure 5 As shown, the clamping mechanism 2 also includes a rotating shaft 23, a mounting cylinder 24, and a limiting screw 25. The rotating shaft 23 is rotatably connected to the mounting plate 21 in a through manner, and the mounting cylinder 24 is fixedly connected to the side wall of the limiting cylinder 22 facing the mounting plate 21.

[0035] like Figure 4 and Figure 5 As shown, one end of the rotating shaft 23 is sleeved inside the mounting cylinder 24, and the limiting screw 25 is installed through the rotating shaft 23 and the mounting cylinder 24. The limiting screw 25 fixes the rotating shaft 23 inside the mounting cylinder 24, thus securing the limiting cylinder 22 and the rotating shaft 23 together. The rotation of the rotating shaft 23 on the mounting plate 21 drives the limiting cylinder 22 to rotate, achieving rotation during workpiece welding. Simultaneously, the detachable limiting screw 25 allows the limiting cylinder 22 to be replaced according to the workpiece, improving the practicality of the equipment. To ensure that the limiting cylinder 22 remains stationary after rotating the workpiece, a limiting element can be provided between the rotating shaft 23 and the mounting plate 21 to restrict the rotation of the rotating shaft 23 on the mounting plate 21. The limiting component can be configured as a damping block that is threadedly connected to the rotating shaft 23 on the side of the mounting plate 21 away from the limiting cylinder 22. By rotating the damping block by thread, the damping block is forced to abut against the side wall of the mounting plate 21, so that the damping block restricts the relative rotation of the mounting plate 21 and the rotating shaft 23.

[0036] like Figure 4 and Figure 5 As shown, the clamping mechanism 2 also includes a threaded sleeve 27, a screw 28 and a mounting ring 29. The threaded sleeve 27 is fixedly connected to the upper outer wall of the limiting cylinder 22, and the mounting ring 29 is fixedly connected to the upper outer wall of the arc-shaped clamping plate 26.

[0037] like Figure 4 and Figure 5 As shown, the screw 28 is threadedly connected to the threaded sleeve 27 in a through-hole manner, and the lower end of the screw 28 is rotatably connected to the mounting ring 29. A flexible protective layer is provided on the inner wall of the arc-shaped clamping plate 26. Through the threaded rotation of the screw 28 on the threaded sleeve 27, the lower end of the screw 28 drives the arc-shaped clamping plate 26 to adjust its vertical position within the limiting cylinder 22, thereby clamping and fixing the workpiece within the limiting cylinder 22 via the arc-shaped clamping plate 26. The flexible protective layer provided on the inner wall of the storage box 16 improves the stability of workpiece clamping while preventing damage to the outer wall of the workpiece during clamping.

[0038] like Figures 1-4 As shown, the clamping mechanism 2 also includes a slide rail 210 formed on the operating table 11, and a pair of sliders 211 slidably connected within the slide rail 210. The lower end of the mounting plate 21 is fixedly connected to the sliders 211. By sliding the sliders 211 within the slide rail 210, the mounting plate 21 can be moved linearly on the operating table 11, thereby adjusting the distance between the pair of limiting cylinders 22. Simultaneously, to ensure that the movement of the sliders 211 within the slide rail 210 requires external force and remains stable without external force, a certain amount of resistance is provided between the sliders 211 and the slide rail 210.

[0039] like Figure 1 and Figure 6 As shown, multiple nozzles 32 are inclined toward the welding torch head 15, allowing the nozzles 32 to spray low-temperature inert gas toward the weld seam, improving air isolation and cooling effects. Furthermore, the multiple nozzles 32 are mounted on the annular gas supply pipe 31 with adjustable angles, allowing the nozzle angles to be adjusted according to the weld seam position. An inlet pipe 33 is installed on the side wall of the annular gas supply pipe 31, and a regulating valve 34 is installed on the inlet pipe 33 to regulate the pressure of the low-temperature inert gas supplied by the inlet pipe 33.

[0040] In use, the linearly moving mounting plate 21 drives the limiting cylinder 22 to move, thereby adjusting the distance between the pair of limiting cylinders 22. Then, the two ends of the workpiece are placed in the pair of limiting cylinders 22 respectively. The adjusting screw 28 drives the arc-shaped clamping plate 26 to clamp and fix the workpiece, so that the two ends of the workpiece are limited and fixed by the cooperation of the limiting cylinder 22 and the arc-shaped clamping plate 26. After the workpiece is fixed, the welding machine 12 can weld the workpiece through the welding gun head 15. During welding, the low-temperature inert gas delivered by the annular gas supply pipe 31 is sprayed to the area around the weld through multiple nozzles 32. The inert gas forms an air curtain around the weld, which isolates the outside air from the weld, thereby preventing the weld from contacting oxygen during welding and preventing the weld from oxidizing. At the same time, the low-temperature nitrogen cools the area around the weld, preventing welding thermal deformation, thereby improving the welding quality of the workpiece. When welding, if the workpiece needs to be rotated, the limiting cylinder 22 can drive the workpiece to rotate, realizing welding at different positions in the circumference of the workpiece, which improves the welding efficiency and makes the welding of the workpiece more convenient.

[0041] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
