Metal pipes mainly consist of various types of steel pipes, including seamless steel pipes, welded steel pipes, alloy steel pipes, cast iron pipes, and non-ferrous metal pipes.

[0003] According to CN216227653U, a metal pipe welding device is disclosed. This technology discloses a "metal pipe welding device, including a sealing cylinder, with circular holes at the middle of both sides of the sealing cylinder, and storage cylinders welded to the inner walls of the circular holes. An observation port is opened on one side of the sealing cylinder, and a transparent cover is hinged to the top of the observation port. Gears that are evenly spaced and distributed in a ring are connected to the inner wall of one side of the sealing cylinder through bearings, and the gears mesh with the same gear ring. The welding equipment body is fixedly connected to the inner circumference of the gear ring. A forward and reverse motor is fixedly connected to the outer wall of one side of the sealing cylinder, and the output shaft of the forward and reverse motor is fixedly connected to one end of one of the gears." This technology has the following technical effects: "It allows one end of two metal pipes to contact each other in the sealing cylinder, which is good preparation for welding and maintains the stability of the metal pipes. It facilitates the ring welding operation of the metal pipes and effectively prevents the sparks generated during the welding process from splashing and preventing the sparks from affecting normal operation."

[0004] In actual use, the welding head of the above-mentioned welding device is located on the toothed ring in the sealed cylinder, which restricts the loading path of the welding wire and affects the flexibility and convenience of use. Utility Model Content

[0027] The main component 11 includes a cylindrical seat 112 fixed to the upper end of the base 111, a bevel gear ring 113 fixed to the outer wall of the cylindrical seat 112, and a guide ring seat 114 fixed to the outer edges of both the front and rear ends of the cylindrical seat 112.

[0030] The execution component 14 is mounted on the feeding component 13 and is used to perform welding work.

[0031] In this embodiment, the welding wire is loaded into the feed tube 133, and then the output end of the second servo motor 1310 drives the drive gear 139 to drive the positioning pressure roller 135 on the positioning gear 134 to rotate. At the same time, the positioning gear 134 drives the limiting pressure roller 138 to rotate through the limiting gear 137, so that the positioning pressure roller 135 and the limiting pressure roller 138 can continuously feed the welding wire into the hose 144 to feed the welding head 143.

[0032] Specifically, the feeding assembly 13 also includes a ball joint 1311 installed inside the upper part of the shaft seat 132, and a threaded knob 1312 rotatably installed inside the shaft bracket 136, with the lower end of the threaded knob 1312 threadedly installed with the ball joint 1311.

[0033] In this embodiment, by rotating the threaded knob 1312 and cooperating with the ball joint 1311, the shaft bracket 136 can be rotated slightly, so that the position of the limiting pressure roller 138 on the limiting gear 137 can be finely adjusted.

[0034] Specifically, the moving component 12 includes a sliding seat 121 disposed on the outside of the cylinder seat 112, and guide wheels 122 rotatably mounted on both ends of the inner wall of the sliding seat 121 and cooperating with the guide ring seat 114.

[0035] In this embodiment, when the sliding seat 121 moves along the circumference of the cylindrical seat 112, it rolls along the guide ring seat 114 via the guide wheel 122, thereby improving the smoothness and stability of the movement process and avoiding shaking of the welding head 143, which would affect the welding.

[0036] Specifically, the moving component 12 also includes an active bevel gear 123 rotatably mounted in the middle of the inner wall of the sliding seat 121 and meshing with the bevel gear ring 113 for transmission, and a first servo motor 124 mounted on the outer wall of the sliding seat 121 for driving the active bevel gear 123.

[0037] In this embodiment, the output end of the first servo motor 124 drives the active bevel gear 123 to rotate, and with the cooperation of the bevel gear ring 113, the moving component 12 moves along the circumference of the cylinder seat 112, and then the two pipes can be welded 360° together by the execution component 14.

[0040] Specifically, rubber sleeves are fixed to the outer walls of the positioning pressure roller 135 and the limiting pressure roller 138, and the surface of the rubber sleeves has a frosted structure.

[0041] In this embodiment, the deformation of the welding wire is avoided by squeezing, and the friction of the welding wire is increased.

[0042] The working principle and usage process of this utility model are as follows: First, pass the ends of the two pipes through the cylinder seat 112, then align the ends of the two pipes and fix them with a clamp.

[0043] Then, the welding wire is loaded into the feed tube 133. By rotating the threaded knob 1312 and cooperating with the ball joint 1311, the shaft bracket 136 can be rotated slightly, so that the position of the limiting pressure roller 138 on the limiting gear 137 is finely adjusted, so that the positioning pressure roller 135 cooperates with the limiting pressure roller 138 to press the welding wire between them.

[0044] Then, the output of the second servo motor 1310 drives the active gear 139 to rotate the positioning pressure roller 135 on the positioning gear 134. At the same time, the positioning gear 134 drives the limiting pressure roller 138 to rotate through the limiting gear 137, so that the positioning pressure roller 135 and the limiting pressure roller 138 can continuously feed the welding wire between them into the hose 144 to feed the welding head 143.

[0045] Finally, the output of the first servo motor 124 drives the active bevel gear 123 to rotate, and with the cooperation of the bevel gear ring 113, the moving component 12 moves along the circumference of the cylinder base 112, so that the two pipes can be welded 360° together by the execution component 14.
