[0062] Working principle:
[0063] When in use, when the pipe is a round pipe, the telescopic rod of the hydraulic rod 23 is stretched, the connecting frame 22 moves upward, the second support plate 21 rotates, the second guide assembly moves downward, the electric roller 12 is started, and the round pipe is transmitted to the direction of the three-axis welding machine 4. When the round pipe moves to the top of the first electric roller 242, the first pressure sensor sends a signal. At this time, the telescopic end of the first electric cylinder 251 is stretched, and the two first arc blocks 26 rotate toward the center of the round pipe. When the second pressure sensor sends a signal, the two first arc blocks 26 clamp the round pipe, and the first auxiliary wheel 263 can guide the round pipe. The first arc block 26 can adapt to round pipes of different sizes;
[0064] In the initial state, the two sets of movable second clamping assemblies are close to the first clamping assemblies. When the round tube is transmitted to the top of the rotating plate 51 and the three first pressure sensors all send signals, the symmetrically distributed first arc blocks 26 clamp the round tube, start the second motor 515, and the second motor 515 rotates to drive the threaded rod 514 to rotate, and the third slider 516 drives the two sets of movable second clamping assemblies to move away from the feeding port.
[0065] When the third slider 516 drives the round tube to move to the bending position, the telescopic end of the first electric cylinder 251 is stretched again, and the first auxiliary wheel 263 is squeezed into the arc groove 262. Then, the fourth motor can be started according to the size of the round tube. The rotation of the fourth motor drives the disc 63 to rotate. When the third auxiliary wheel 632 rolls to the raised part of the cam 64, the telescopic spring 634 is stretched, and the corresponding first bending wheel 641 or the second bending wheel 642 is pushed out from the disc 63.
[0066] The second electric cylinder 61 is started, the telescopic rod of the second electric cylinder 61 is stretched, and the first bending wheel 641 or the second bending wheel 642 bends the round tube. After the round tube is bent, the fourth motor on the other side is started, and the fourth motor rotates to drive the disc 63 to rotate, and the corresponding first arc clamping block 65 and second arc clamping block 651 are pushed out from the disc 63. The second electric cylinder 61 on the other side is started, and the telescopic rod of the second electric cylinder 61 is stretched. The first arc clamping block 65 and the second arc clamping block 651 clamp the bent pipe to prevent deformation during welding. Then the three-axis welding machine 4 performs welding. When the bending corner is not easy to weld, the second electric roller 54 rotates to drive the round tube to rotate;
[0067] When the pipe is a square pipe, the telescopic rod of the hydraulic rod 23 is compressed, the connecting frame 22 moves downward, the second support plate 21 rotates, the first guide assembly moves downward, the electric roller 12 is started, and the square pipe is transmitted to the direction of the three-axis welding machine 4. The second auxiliary wheel 273 can guide the square pipe, and the first support seat 27 can adapt to square pipes of different sizes, and the switching for pipes of different shapes is more flexible;
[0068] The first motor 33 is started, and the rotation of the first motor 33 drives the rotating plate 51 to rotate, and the second clamping module rotates to the upper side. In the initial state, the two groups of movable fourth clamping components are close to the third clamping component. When the square tube is transferred to the upper side of the rotating plate 51, the contact sensor at the bottom of the second auxiliary wheel 273 sends a signal, and the second motor 515 is started. The third slider 516 drives the two groups of movable fourth clamping components to move away from the feeding port, and the fourth motor is started. The corresponding second bending block 644, the first bending block 643, the first clamping block 652 and the second clamping block 653 are pushed out from the disc 63;
[0069] The second bending block 644 and the first bending block 643 bend the square tube, the first clamping block 652 and the second clamping block 653 clamp the bent tube, and then the three-axis welding machine 4 welds it. When the bending corner is not easy to weld, the third motor 552 rotates to drive the gear 551 to rotate, and the circular plate 271 also rotates, driving the clamped square tube to rotate.
