[0021] When bending metal profiles of different specifications, templates with corresponding arc shapes and sizes need to be used, and to ensure the installation stability of the templates, the templates need to be fixed at multiple points.

Under the cooperation of the fixed threaded rod 25 and the fixed slide rod 26, the fixed push plate 27 is driven to move, and the fixed push plate 27 drives the fixed pin 3 to move out of the fixing hole 7 of the fixing column 6 of the original template 4. At this time, the template 4 lacks a fixing mechanism, and the template 4 can be directly removed from the operating table 1; Then, the fixing column 6 of the template 4 to be used corresponds to the mounting hole 2, the template 4 is mounted on the operating table 1, and the fixing motor 28 is started to rotate in the opposite direction. The fixing motor 28 drives the fixing threaded rod 25 to rotate, and the fixing push plate 27 is driven to move under the cooperation of the fixing threaded rod 25 and the fixing slide bar 26.

After the installation of the clamp 8 is completed, the metal profile to be bent is manually placed between the clamp plate 15 of the clamp 8 and the bottom wall of the clamp 8; The driving motor 20 is started, and the driving motor 20 drives the driving threaded rod 19 to rotate. Under the driving of the driving threaded rod 19 and the guiding cooperation of the guide slide rod 21, the driving block 22 drives the rack 11 to move. When the rack 11 moves, it drives the driving gear 13 to rotate by meshing with the driving gear 13. The driving gear 13 drives the nut tube 12 to rotate. Under the cooperation of the guide slide groove 16, the clamping threaded rod 14 drives the clamping plate 15 to move. The clamping plate 15 cooperates with the bottom wall of the clamp 8 to clamp and fix the metal profile. (3) The metal profile with the clamp 8 installed is manually removed from the support frame 17, and the distance between the two sets of clamping frames 34 is controlled by the telescopic cylinder 37 to adapt to the length of the metal profile. The two ends of the metal profile are respectively placed in the two sets of clamping frames 34, and the clamping cylinder 35 is started. The clamping cylinder 35 drives the clamping plate 36 to move, and the clamping plate 36 cooperates with the clamping frame 34 to clamp and fix the metal profile; (4) Start the push cylinder 38, which pushes the operating platform 1 close to the metal profile and makes the metal profile contact with the surface of the template 4. Start the bending cylinder 33, and under the action of the bending cylinder 33, the template 4 is bent by two sets of clamping frames 34.
