Under the guidance and cooperation of the guide rod 20, the bidirectional screw 19 drives the two groups of clamping plates 21 to approach each other and clamp one end of the seat bracket;

[0035] 2. Driven by the first electric cylinder 7 and guided by the support slide bar 8, the feeding push plate 9 is driven to move toward the bending column 10 to feed the seat bracket, and the seat bracket being fed is engaged and slid in the bracket fitting groove 13;

[0036] During the feeding process, the guide plate 26 is driven to move by the fourth electric cylinder 25, and the seat bracket is engaged and slidably arranged in the limiting guide groove 27 of the guide plate 26 and the bracket fitting groove 13;

[0037] 3.

Under the action of the clamping mechanism 5, the two sets of clamping plates 21 cooperate to clamp and fix the other end of the seat bracket;

[0038] 4. Start the bending motor 11. The bending motor 11 drives the corresponding clamping mechanism 5 to rotate through the bending drive plate 12. The clamping mechanism 5 drives the seat bracket to bend along the bracket fitting groove 13. The rotation angle of the bending motor 11 determines the bending arc.

[0039] 5. After this part of the bending is completed, the feeding mechanism 2 is used to feed the material according to the next bending length and position, and the seat bracket can be driven to rotate to a suitable angle by rotating the motor 23, so that the corresponding bending direction can be adjusted.
