[0024] The first bevel gear 304 meshes with the second bevel gear 607 .

[0025] Working principle: First, place the steel sheet pipe to be curved on the upper end surface of the curved support block 2. At this time, starting the second drive motor 406 will drive the first threaded rod 405 to rotate, thereby driving the second rotating belt 407 to rotate, and then driving the first threaded rod 405 connected at both ends of the second rotating belt 407 to rotate. As the first threaded rod 405 rotates, it will drive the rectangular lifting block 403 to move downward, thereby driving the U-shaped support block 401, the guide block 402 and the pushing assembly 404 to move downward until the lower end surface of the curved pushing block 413 contacts the upper end surface of the curved support block 2, and the curved pushing block 413 contacts the curved steel sheet pipe; When the lower end surface of the arc-shaped pushing block 413 contacts the upper end surface of the arc-shaped supporting block 2, the third driving motor 408 is started, and the third rotating belt 409 is driven to rotate, thereby driving the bidirectional threaded rod 410 to rotate, and then driving the T-shaped connecting block 414 to move along the T-shaped slide toward the direction of the circular supporting block 312, and driving the arc-shaped pushing block 413 to move toward the direction of the circular supporting block 312, and then driving the arc-shaped steel sheet tube to move along the arc-shaped supporting block 2 toward the arc-shaped groove 313, until the T-shaped connecting block 414 moves to the other end of the T-shaped slide; When the T-shaped connecting block 414 moves to the other end of the T-shaped slide groove, the two arc-shaped steel sheet tubes will contact each other, so that the junction of the two arc-shaped steel sheet tubes and the horizontal center line of the groove 314 are in the same plane, and the trigger block 415 coincides with the trigger groove provided on the surface of the first controller 5. At this time, the first drive motor 301 is started to rotate forward, and the inner gear ring 302 is driven to rotate, thereby driving the first gear 303 to rotate, and then driving the first bevel gear 304 to rotate. As the first bevel gear 304 rotates, the second bevel gear 607 is driven to rotate, thereby driving the second bevel gear 607 to rotate. The threaded rod 602 rotates, thereby driving the welder 606 and the electromagnetic slide rail 603 to move downward. When the inner gear ring 302 rotates one circle, the welding point of the welder 606 contacts the junction of the two arc-shaped steel sheet tubes. At this time, the welder 606 performs a welding operation on the junction, and then the electromagnetic slider 604 moves left and right along the electromagnetic slide rail 603. During the movement of the electromagnetic slider 604, the electric telescopic rod 605 automatically retracts and retracts, so that the welding point of the welder 606 always contacts the junction of the two arc-shaped steel sheet tubes until the welding operation is completed; After welding is completed, the first driving motor 301 rotates in reverse for one circle, so that the welder 606 gradually returns to its original position, and drives the ratchet wheel 306 to rotate in reverse, thereby driving the ratchet 307 to rotate in reverse for one circle, and then drives the second gear 308 to rotate for one circle. As the second gear 308 rotates, the third gear 309 is driven to rotate 180 degrees, thereby driving the first circular rotating rod 310 to rotate, and then driving the first rotating belt 311 to rotate. The rotation of the first rotating belt 311 drives the circular supporting block 312 to rotate 180 degrees, thereby driving the two arc-shaped steel sheet tubes to perform reverse operation, so that the back of the arc-shaped steel sheet tube is located directly below the welder 606; When the back side of the arc-shaped steel sheet pipe is directly below the welder 606, the welder 606 is restored to its original position, and then the first drive motor 301 is started to rotate forward, thereby driving the welder 606 to perform welding operation on the back side junction of the two arc-shaped steel sheet pipes until the welding operation is completed, thus ending all operations.
