A bolt is installed on one side of the rotating cylinder 3. A welding head 13 is slidably installed on one side of one side of the fixed bracket 6, and an air gun 15 is slidably installed on one side of the other side of the fixed bracket 6. The second support frame 17 is symmetrically arranged on the outside of the fixed top frame 2 and is fixedly connected to the support base plate 1. The second cylinder 18 is installed on the top of the second support frame 17. The third cylinder 20 is installed inside the second support frame 17. The output ends of the second cylinder 18 and the third cylinder 20 are both fixedly connected to the adjustment frame 21. The conveying roller 22 is rotatably arranged inside the adjustment frame 21.

[0029] It should be noted that in this embodiment, the pipe is roll-formed by the upper and lower forming rollers 25 inside each of the third support frames 24, and the pipe is guided and limited by the first forming roller 16 rotating inside the first support frame 14. The output end of the second cylinder 18 drives the adjusting frame 21 and the inner conveying roller 22 to move up and down. The output end of the third cylinder 20 drives the adjusting frame 21 and the conveying roller 22 at the output end to adjust their positions up and down, thereby adjusting the distance between the upper and lower conveying rollers 22. The output end of the second motor 23 drives the conveying roller 22 to rotate, and the upper and lower sets of conveying rollers 22 rotate in opposite directions to weld and convey the pipe. The output end of the first motor 9 drives the gear 8 to rotate. 8. When rotating, the meshing teeth 5 and inner limit ring 4 are driven to rotate. The inner limit ring 4 drives the rotating cylinder 3 on one side to rotate. The rotating cylinder 3 drives the side fixing bracket 6, welding head 13 and air gun 15 on one side to rotate. The position of the welding head 13 for welding pipe is adjusted. Gas and oxygen are supplied through the air gun 15. The output end of the first cylinder 12 drives the inner sliding block 10 to slide on the outside of the limit rod 11. The inner sliding block 10 slides on the inside of the side fixing bracket 6 to adjust the extension position of the welding head 13 and the extension position of the air gun 15 to adapt to different pipe welding scenarios. The side fixing bracket 6 is installed on one side of the rotating cylinder 3 by bolts. The installation angle of the side fixing bracket 6 can be changed according to the opening of different threaded holes.

A second limiting rod 26 is symmetrically slidably arranged inside the second support frame 17, and another adjusting frame 21 is fixedly connected to the second limiting rod 26.

[0035] It should be noted that, in this embodiment, the output end of the second cylinder 18 drives one of the adjusting frames 21 and the conveying roller 22 to move. One of the adjusting frames 21 drives the first limiting rod 19 to move synchronously. The first limiting rod 19 slides in a limited position with the second support frame 17. The output end of the third cylinder 20 drives the other adjusting frame 21 and the conveying roller 22 to move. The other adjusting frame 21 drives the second limiting rod 26 at the bottom to move synchronously.
