In addition, the distance between the front conveying roller table 5 and the rear conveying roller table 7 is less than the length of the plate to be processed 2, and the front conveying roller table 5 and the rear conveying roller table 7 can cooperate to make the plate to be processed 2 advance or retreat , to realize the adjustment of the forward or backward position of the plate 2 to be processed.

The flattening machine 6 is the main working equipment, which can carry out targeted flattening and straightening work on the parts of the steel plate with shape quality problems. The forward and backward position adjustment of the steel plate 11 is realized by the conveying roller table 5 in front of the machine and the conveying roller table 7 in the rear of the machine. The depressing hydraulic cylinder 64 installed on the frame 61 can roll laterally on the top of the frame 61 by means of the wheels 65 under the drive of the traverse hydraulic cylinder 62 to adjust the position of the pressure head 63 on the steel plate 11 laterally.

The plate to be processed 2 realizes the forward and backward movement through the conveying roller table 5 in front of the machine and the conveying roller table 7 in the rear of the machine; presses down the hydraulic cylinder 64 to realize the lateral movement action by relying on the lateral movement hydraulic cylinder 62; through the plate length measuring device 4 and the mechanical plate The shape defect position of the steel plate recorded by the type detection device 1 can realize the automatic detection of the entire steel plate surface and the position adjustment and flattening action. The flattening machine 6 also applies different pressing forces according to the quality of the plate shape detected by the photoelectric-mechanical plate shape detection device 1 . After completing the straightening work of all plate shape defects of the steel plate, the steel plate is transported to the exit through the post-machine conveying roller table 7, and the straightened steel plate is transported to the finished product warehouse through the crane.
