[0027] The following is combined with Figure 1 -Attached Figure 5 The present invention is described in further detail.

[0028] The embodiment of the present invention discloses an automatic straightening device for steel sections. Figure 1 and Figure 2 The automatic straightening equipment for steel sections includes an input device 1, an operating table 2, an output device 3, a straightening mechanism 4, an operation controller 5, an inspection platform 6 and a position adjustment mechanism 7. The steel sections to be straightened are transported to the operating table 2 through the input device 1 and are output by the output device 3 after a series of processing steps.

[0029] Reference Figure 1 and Figure 2The input device 1 and the output device 3 both adopt the structure of roller transmission, which can accurately control the spacing and angle of each roller. The operating table 2 is located between the input device 1 and the output device 3, and is used to provide a processing area for the steel section. The operating table 2 is also provided with a roller structure for conveying the steel section. The operating table 2 is equipped with a device controller 20 using a PLC control system, and the output device 3 is equipped with a first displacement sensor (not shown in the figure). The first displacement sensor is used to detect whether the steel section is conveyed in place and to provide feedback to the device controller 20. The device controller 20 controls the input device 1 and the output device 3 to work, so as to accurately control the position of the steel section, realize the gradual straightening of the steel section, and improve the straightening accuracy and efficiency.

[0030] Reference Figure 1 and Figure 3 The straightening mechanism 4 is used to apply pressure to the bending point of the steel section. The straightening mechanism 4 includes a hydraulic cylinder 40 installed on one side of the operating table 2. The extension direction of the hydraulic cylinder 40 is perpendicular to the conveying direction of the steel section. A raindrop-shaped baffle 400 is installed on the piston rod of the hydraulic cylinder 40. A second displacement sensor 21 is installed at the position corresponding to the baffle 400 on the operating table 2. The second displacement sensor 21 can detect the moving distance of the baffle 400, thereby detecting whether the extension length of the piston rod of the hydraulic cylinder 40 reaches the set value, so as to feedback to the equipment controller 20 and shut down the hydraulic cylinder 40.

[0031] Reference Figure 3 and Figure 4 Two main support plates 41 are installed on the other side of the operating table 2 for rigidly supporting the steel section when the hydraulic cylinder 40 pushes the steel section. The steel section is located between the hydraulic cylinder 40 and the two main support plates 41. The spacing between the two main support plates 41 is not less than 1m. The force application point of the hydraulic cylinder 40 on the steel section is located in the middle position of the two main support plates 41.

[0032] Reference Figure 1 and Figure 4 Two auxiliary support plates 42 are also installed on the operating table 2 for use with the hydraulic cylinder 40 when the bending length of the steel section is small. The two auxiliary support plates 42 are located between the two main support plates 41. The length of the auxiliary support plates 42 perpendicular to the direction of travel of the steel section is less than the length of the main support plates 41 perpendicular to the direction of travel of the steel section. There is a gap between the auxiliary support plates 42 and the steel section. Pads 43 are hinged on the auxiliary support plates 42. Pads 43 are located on the side of the auxiliary support plates 42 in the non-working state. When pads 43 are needed, the staff can manually rotate the pads 43 so that the pads 43 abut against the front end surface of the auxiliary support plates 42, thereby supporting the steel section through the pads 43.

[0033] Reference Figure 1 and Figure 4The inspection platform 6 is installed on the side of the operating platform 2 where the main support plate 41 is provided. The length direction of the inspection platform 6 is the same as the moving direction of the steel section. The length of the inspection platform 6 is not less than the maximum length of the steel section, so as to facilitate the inspection of steel sections of various lengths. Two operation controllers 5 are provided and installed on the side of the inspection platform 6 away from the steel section. One of the operation controllers 5 is used to manually control the input device 1 and the output device 3 to work, thereby controlling the position of the steel section, and the other operation controller 5 is used to manually control the position adjustment mechanism 7 and the hydraulic cylinder 40.

[0034] Reference Figure 4 and Figure 5 A third displacement sensor 22 is provided below the inspection platform 6, and is used for automatically straightening the steel. The moving head 220 on the third displacement sensor 22 is provided on a side close to the steel, and the third displacement sensor 22 is installed on the operating table 2. The third displacement sensor 22 uses the displacement of the moving head 220 after the steel is pushed and deformed by the hydraulic cylinder 40 to feedback to the equipment controller 20 whether the steel is straightened properly.

[0035] Reference Figure 1 and Figure 3 The position adjustment mechanism 7 is arranged on the operating platform 2, and is used to transport the steel section from the roller structure upward to the inspection platform 6, so that the staff can carry the steel section to the inspection platform 6. The position adjustment mechanism 7 includes a slide 70, a slide rail 71 and a drive assembly 72. The slide rail 71 is vertically installed on the outer side of the operating platform 2, the slide 70 is vertically slidably connected to the slide rail 71, and the drive assembly 72 includes a drive motor 720, a sprocket 721 and a chain 722.

[0036] Reference Figure 1 and Figure 3 The driving motor 720 drives the sprocket 721 to rotate through the reducer, and the chain 722 is meshed between the upper and lower sprockets 721. The slide 70 is installed on the chain 722. The slide 70 moves up and down under the drive of the chain 722, thereby achieving the purpose of lifting or lowering the steel. A row of rollers 700 are arranged on the top surface of the slide 70 along the extension direction of the hydraulic cylinder 40. Each roller 700 is independently connected to the slide 70 by rolling. The axis direction of the roller 700 is perpendicular to the extension direction of the hydraulic cylinder 40. The steel rolls in contact with the roller 700, so that the hydraulic cylinder 40 can push the steel to move closer to the inspection platform 6, thereby reducing the wear on the steel.

[0037] The implementation principle of the automatic straightening equipment for steel sections in the embodiment of the present invention is as follows: according to the bending length of the steel section, it is divided into two parts: automatic straightening and manual straightening. Automatic straightening supports processing steel sections with a length of more than 1.5m, and manual straightening supports processing steel sections with a length of more than 0.6m.

[0038] When the steel section is processed by automatic straightening, the steel section to be processed is transported to the straightening position on the operating table 2 through the input device 1. After the first displacement sensor detects that the steel section is in place, it feeds back to the equipment controller 20. The equipment controller 20 controls the input device 1 and the output device 3 to stop running, and controls the position adjustment mechanism 7 to work according to the straightening parameters and real-time data, and the slide 70 lifts the steel section a certain distance.

[0039] The equipment controller 20 controls the hydraulic cylinder 40 to extend a certain length to push the steel section to the two main support plates 41. The second displacement sensor 21 detects that the baffle 400 has moved a set distance and then feeds back to the equipment controller 20 to control the hydraulic cylinder 40 to stop extending. During this process, the moving head 220 of the third displacement sensor 22 is pushed by the steel section. If the movement amount of the moving head 220 does not reach the set amount required for the qualified straightening of the steel section, the feedback equipment controller 20 will perform the pushing work again. The second extension amount of the hydraulic cylinder 40 will be greater than the first extension amount. This process is repeated 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 steel section is output by the output device 3.

[0040] When the steel is processed by manual straightening, the staff manually controls the input device 1, the output device 3 and the position adjustment mechanism 7 by operating the controller 5 to adjust the straightening point of the steel. The pad 43 is rotated to the front end of the auxiliary support plate 42, and then the hydraulic cylinder 40 is manually controlled to extend and retract by operating the controller 5. The steel is supported on the two pads 43. After multiple adjustments and optimizations, the straightened steel that meets the requirements is obtained and output by the output device 3. When the straightening effect needs to be manually checked, the staff operates the controller 5 to control the slide 70 to rise again, and the steel is transported to the vicinity of the inspection platform 6, and then the steel is manually moved to the inspection platform 6 for inspection.

[0041] This automatic straightening equipment for steel sections achieves the goal of single-person control of multiple devices. It is simple and convenient to operate, reduces labor intensity, reduces labor costs, and thus improves the efficiency of steel section straightening; it ensures the controllability of the production process and the safety of personnel. The application of automatic control technology and precise positioning technology reduces the damage caused by the transportation and handling of steel sections, thereby improving product quality; it can switch between automatic straightening and manual straightening according to the length of the steel section, and the adaptation range of steel section straightening is wider.

[0042] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
