[0025] The bending mechanism 5 includes a bending surface 51, two bending tracks 52, a pressure rod 53, and two rotating plates 54. The bending surface 51 is U-shaped and is arranged at the discharge end of the base 1. The two bending tracks 52 are arranged on both sides of the bending surface 51. Specifically, the bending track 52 is a fixed plate, which is arranged on the side of the discharge end of the base 1. The fixed plate is provided with a through groove, which corresponds to the bending surface 51. The pressure rod 53 is arranged across the bending surface 51, and both ends of the pressure rod 53 extend out of the through groove of the fixed plate.

After being conveyed to the specified position, the part of the bending plate that needs to be bent leaves the upper conveying roller 21 and the lower conveying roller 22 and is located above the bending surface 51 and below the pressure rod 53. After the upper conveying roller 21 and the lower conveying roller 22 stop conveying, the upper conveying roller 21, the lower conveying roller 22, the first column 31 and the second column 32 limit the part of the bending plate that does not need to be bent, that is, fix the bending plate.

After the bending plate is bent to the bottom, the bending is completed. The upper conveying roller 21 and the lower conveying roller 22 continue to rotate to convey the bending plate. Here, the bending plate is simultaneously translated horizontally from the device to be removed with the robot.
