At the same time, through the coordinated use of the driving assembly, the clamping table 17 and the auxiliary positioning mechanism, the precise bending of the metal pipe can be realized.

[0022] In this embodiment, the driving assembly includes a single-rod cylinder, which is a common product on the market and can be directly purchased. The single-rod cylinder includes a piston cylinder 8 and a piston rod 7 associated with the piston cylinder 8. One end of the piston rod 7 is connected with a serrated linkage block 6. The back surface of the serrated linkage block 6 cooperates with the clamping block 2. Through the cooperation of the piston rod 7 and the serrated linkage block 6, the control of the clamping block 2 is realized, thereby completing the bending operation of the metal pipe.

[0023] In this embodiment, a main shaft 22 is provided at the center of the clamping table 17. A first linkage table 21 is provided at the top of the main shaft 22, and a second linkage table 25 is provided at the bottom. A transmission gear 19 is provided at the top of the first linkage table 21. The transmission gear 19 is associated with the serrated linkage block 6. A bending guide wheel 18 is provided at the top of the transmission gear 19. The main shaft 22 cooperates with the first linkage table 21, the transmission gear 19, and the bending guide wheel 18 in sequence.

[0025] In this embodiment, an auxiliary bending rod 3 is movably connected to the bottom of the second linkage table 25. A transmission shaft 26 is connected to the bottom of the auxiliary bending rod 3. A servo motor 27 is connected to the bottom of the transmission shaft 26. The servo motor 27 is a common product on the market and can be directly purchased. A motor fixing plate 24 is provided at the bottom of the servo motor 27. The motor fixing plate 24 is associated with the workbench 14.

Fix the metal pipe in place by using the clamping table 17 and the clamping block 2. The clamping table 17 is located between the H-shaped fixing base and the first L-shaped fixing base 1, and the clamping block 2 is in close contact with the metal pipe to prevent it from sliding or deforming during the bending process. Start the driving component, and the single-rod cylinder starts to work. The piston rod 7 pushes the serrated linkage block 6 to move. The serrated linkage block 6 meshes with the transmission gear 19, driving the transmission gear 19 to rotate. The rotation of the transmission gear 19 further drives the main shaft 22 to rotate. While the main shaft 22 is rotating, the servo motor 27 drives the auxiliary bending rod 3 to perform the bending operation through the transmission shaft 26. The auxiliary bending rod 3 contacts the metal pipe and applies additional force to help complete the bending. When the metal pipe reaches the predetermined bending angle, the driving component stops working, and the main shaft 22 and the auxiliary bending rod 3 also stop moving accordingly. At this time, the metal pipe has successfully completed the bending operation.
