The screw rod 224 will drive the transmission frame 225 to move the transmission frame 225 up and down. The up and down movement of the transmission frame 225 drives the connecting block 226 to move up and down to press down the steel structure. At the same time, the screw rod 224 and the transmission frame 225 are upper and lower transmission components, which can be replaced with other hydraulic transmissions. The screw rod 224 drives its distance for easy control.

[0030] Working principle: The steel structure to be bent is placed on the placement plate 115, and the steel structure is in contact with the anti-skid transmission roller 214. At this time, the first motor 211 cooperates with the transmission wheel 212 to drive the two sets of anti-skid transmission rollers 214 to rotate, and the anti-skid transmission rollers 214 drive the steel structure to be transported. If a part of the steel structure needs to be bent, the second motor 223 is controlled, and the second motor 223 drives the screw rods 224 on both sides to rotate. At this time, the two sets of screw rods 224 drive the transmission frame 225 to drive the connecting block 22 6 performs synchronous up and down displacement. At this time, the lower pressure roller 228 moves downward to squeeze the steel structure. The downward pressure distance of the lower pressure roller 228 is adjusted as needed. (At this time, the positioning plate 221 can bend back and forth alternately to make the bending angle more gentle. At the same time, the positioning plate 221 can stop rotating, so that the lower pressure roller 228 directly presses down to bend the steel structure.) After bending, the second motor 223 drives the lower pressure roller 228 to move upward, and the positioning plate 221 continues to drive the steel structure to move, and bends again at the appropriate position.
