The equipment controller 20 controls the operation of the input device 1 and the output device 3, so as to accurately control the position of the section steel, realize the gradual straightening of the section steel, and improve the straightening accuracy and efficiency.

[0034] With reference to Figure 1 and Figure 3 , the straightening mechanism 4 is used to apply pressure to the bending point of the section steel. The straightening mechanism 4 comprises a hydraulic cylinder 40 installed on one side of the operation table 2. The extension direction of the hydraulic cylinder 40 is perpendicular to the conveying direction of the section steel. A raindrop-shaped baffle 400 is installed on the piston rod of the hydraulic cylinder 40. A second displacement sensor 21 is installed on the operation table 2 corresponding to the position of the baffle 400. The second displacement sensor 21 can detect the moving distance of the baffle 400, so as to detect whether the extension length of the piston rod of the hydraulic cylinder 40 reaches the set value, and feed back to the equipment controller 20 and shut down the hydraulic cylinder 40.

[0035] With reference to Figure 3 and Figure 4 , the other side of the operation table 2 is also provided with two main support plates 41 for rigidly supporting the section steel when the hydraulic cylinder 40 pushes the section steel.

During the automatic straightening process of the profile steel, the moving head 220 of the third displacement sensor 22 is arranged on the side close to the profile steel. The third displacement sensor 22 is installed on the operation table 2. The third displacement sensor 22 feeds back to the equipment controller 20 whether the profile steel is straightened qualified through the displacement of the moving head 220 moved by the profile steel deformed by the hydraulic cylinder 40.

[0039] With reference to Figure 1 and Figure 3 , the position adjusting mechanism 7 is arranged on the operation table 2, which is used to transport the profile steel upward from the roller structure to the inspection platform 6, so as to facilitate the worker to carry the profile steel to the inspection platform 6.

[0041] The implementation principle of the profile steel automatic straightening equipment in the embodiment of the utility model is as follows: according to the bending length of the profile steel, the profile steel is divided into automatic straightening and manual straightening two parts, the automatic straightening supports the processing of the profile steel with a length of more than 1.5m, and the manual straightening supports the processing of the profile steel with a length of more than 0.6m.

[0042] When the profile steel is processed in the automatic straightening mode, the profile steel to be processed is conveyed to the straightening position on the operation table 2 through the input device 1, the first displacement sensor feeds back the equipment controller 20 after detecting that the profile steel is in place, the equipment controller 20 controls the input device 1 and the output device 3 to stop running, and controls the position adjusting mechanism 7 to work according to the straightening parameters and real-time data, and the sliding base 70 lifts the profile steel by a certain distance.

[0043] The equipment controller 20 controls the hydraulic cylinder 40 to extend by a certain length to push the profile steel to the two main supporting plates 41, the second displacement sensor 21 feeds back the equipment controller 20 after detecting that the baffle 400 moves by a set distance, and the equipment controller 20 controls the hydraulic cylinder 40 to stop extending, in this process, the moving head 220 of the third displacement sensor 22 is pushed by the profile steel, if the moving amount of the moving head 220 does not reach the set amount required for the profile steel to be straightened, the equipment controller 20 is fed back to push again, the extension amount of the hydraulic cylinder 40 in the second time will be greater than that in the first time, and this process is repeated for many times until the straightening is completed, finally the equipment controller 20 starts the input device 1 and the output device 3 again, and the profile steel is output by the output device 3.

[0044] When the profile steel is processed in the manual straightening mode, the staff manually controls the input device 1, the output device 3 and the position adjusting mechanism 7 through the operation controller 5, and adjusts the straightening point of the profile steel.
