Abstract
Description
Technical Field
[0001] This application relates to the technical field of steel structure processing, and in particular to a straightening device for steel structure processing. Background Technology
[0002] H-beams are a representative type of steel structure. They are an economical cross-sectional profile with optimized cross-sectional area distribution and a reasonable strength-to-weight ratio. They are named for their cross-sectional shape, which resembles the letter "H". Because all parts of an H-beam are arranged at right angles, it has advantages such as strong bending resistance in all directions, simple construction, cost savings, and light structural weight. It has been widely used in various civil and industrial building structures.
[0003] Regarding the aforementioned related technologies, the inventors believe that H-beams often undergo deformation during processing due to external forces, welding, and uneven heating, thus requiring correction. Existing correction devices can only compress and correct the perpendicularity and flatness of H-beams. When H-beams undergo compressive deformation perpendicular to the flange direction, existing devices are not convenient for extending the deformed parts. Therefore, to solve the above problems, this application provides a correction device for steel structure processing. Utility Model Content
[0004] In order to solve the problems mentioned in the background art, this application provides a straightening device for steel structure processing.
[0005] This application provides a straightening device for steel structure processing, including a base and a limiting assembly. The surface of the base is provided with a horizontal groove. A servo motor is fixedly connected to the inner wall of one end of the horizontal groove. The output end of the servo motor is fixedly connected to a bidirectional lead screw through a coupling. Two sliders are symmetrically threaded to the outside of the bidirectional lead screw. A U-shaped straightening plate is fixedly connected to the top of each slider. An L-shaped plate is fixedly connected to the surface of the base. A first electric telescopic rod is fixedly connected to the inner wall of the top of the L-shaped plate. A straightening horizontal plate is fixedly connected to the output end of the first electric telescopic rod.
[0006] Preferably, the limiting component includes a first fixing plate fixedly connected to the base surface and located on the rear side of the transverse groove, a second electric telescopic rod fixedly connected to the base surface and located on the front side wall of the transverse groove, and the output end of the second electric telescopic rod fixedly connected to the second fixing plate.
[0007] Preferably, a placement platform is fixedly installed inside the transverse groove, the bidirectional lead screw passes through the placement platform, and the top of the placement platform is flush with the upper surface of the base.
[0008] Preferably, an H-beam is placed on the surface of the placement platform and between the two U-shaped straightening plates.
[0009] Preferably, the end of the bidirectional lead screw away from the servo motor is rotatably connected to the inner wall of the transverse groove.
[0010] In summary, this application includes the following beneficial technical effects:
[0011] The H-beam is placed on a platform, and its position is limited by a limiting component, facilitating the straightening operation. A servo motor drives a bidirectional lead screw to rotate, which in turn moves two external sliders and two U-shaped straightening plates closer together. The U-shaped straightening plates press down on the deformed areas, restoring the verticality and flatness of the H-beam's web. Activating a first electric telescopic rod moves a straightening crossbar towards the flange of the H-beam that needs straightening, pressing down on the flange and restoring its verticality and flatness. Compared to existing technologies, this application enables comprehensive pressing and straightening of the H-beam's flange and web, improving the straightening effect. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.
[0017] Example 1:
[0018] A straightening device for steel structure fabrication, as described above. Figure 1 - Figure 4The system includes a base 1 and a limiting assembly. A horizontal groove 2 is formed on the surface of the base 1. A servo motor 3 is fixedly connected to the inner wall of one end of the groove 2. A bidirectional lead screw 4 is fixedly connected to the output end of the servo motor 3 via a coupling. Two sliders 5 are symmetrically threaded onto the outside of the bidirectional lead screw 4. U-shaped straightening plates 6 are fixedly connected to the top of each slider 5. An L-shaped plate 7 is fixedly connected to the surface of the base 1. A first electric telescopic rod 8 is fixedly connected to the inner wall of the top of the L-shaped plate 7. A straightening horizontal plate 9 is fixedly connected to the output end of the first electric telescopic rod 8. When the servo motor 3 is started, it drives the bidirectional lead screw 4 to rotate, which in turn drives the two external sliders 5. The slider 5 moves inside the transverse groove 2, and its bottom is in close contact with the bottom of the transverse groove 2. This prevents the slider 5 from rotating or shifting when it moves outside the double-acting screw 4. The movement of the slider 5 drives the two U-shaped straightening plates 6 to move closer to each other until the outer wall of the web of the U-shaped straightening plate 6 is pressed against the H-beam 14. The U-shaped straightening plate 6 is used to press the deformed part, thereby restoring the verticality and flatness of the web of the H-beam 14 and achieving the straightening effect. By activating the first electric telescopic rod 8, the first electric telescopic rod 8 drives the straightening cross plate 9 to move towards the flange of the H-beam that needs to be straightened, thereby pressing the flange of the H-beam 14 and restoring the verticality and flatness of the flange of the H-beam 14.
[0019] Reference Figure 2 and Figure 3 The limiting component includes a first fixing plate 10 fixedly connected to the surface of the base 1 and located on the rear side of the transverse groove 2, and a second electric telescopic rod 11 fixedly connected to the surface of the base 1 and located on the front side wall of the transverse groove 2. The output end of the second electric telescopic rod 11 is fixedly connected to the second fixing plate 12. The H-beam 14 is placed on the placement platform 13, and the rear side wall of the placement platform 13 is tightly fitted with the first fixing plate 10. By activating the second electric telescopic rod 11, the second electric telescopic rod 11 drives the second fixing plate 12 to move toward the H-beam 14, thereby achieving clamping and fixing of the H-beam 14 and preventing the H-beam 14 from shifting position during correction.
[0020] Reference Figure 3 and Figure 4 A placement platform 13 is fixedly installed inside the transverse groove 2. A two-way lead screw 4 passes through the placement platform 13, and the top of the placement platform 13 is flush with the upper surface of the base 1.
[0021] Reference Figure 4 An H-beam 14 is placed on the surface of the placement table 13 and between two U-shaped straightening plates 6, which facilitates the straightening operation of the H-beam 14.
[0022] Reference Figure 4 The end of the bidirectional lead screw 4 away from the servo motor 3 is rotatably connected to the inner wall of the transverse groove 2, and the bidirectional lead screw 4 can rotate inside the transverse groove 2.
[0023] The implementation principle of a straightening device for steel structure processing according to an embodiment of this application is as follows: The servo motor 3 is preferably of type HBS57, and the first electric telescopic rod 8 and the second electric telescopic rod 11 are both preferably of type LX600. The servo motor 3, the first electric telescopic rod 8, and the second electric telescopic rod 11 are all electrically connected to an external power source via a switch. The H-beam 14 is placed on the placement platform 13, ensuring that the rear side wall of the placement platform 13 is tightly fitted against the first fixing plate 10. The second electric telescopic rod 11 is activated by the switch, causing the second fixing plate 12 to move towards the H-beam 14, thereby clamping and fixing the H-beam 14, facilitating the straightening operation of the H-beam 14. The servo motor 3 is activated by the switch, causing the bidirectional lead screw 4 to rotate. The threads on both sides of the bidirectional lead screw 4 have opposite directions, equal pitch, and a thread angle of [missing information]. The angle is 20 degrees. The thread self-locking condition can be calculated by the following formula: Self-locking condition = friction coefficient × tan (helix angle) ≥ 1. The rotation of the double-acting screw 4 drives the two sliders 5 outside it to move inside the transverse groove 2. The bottom of the slider 5 is in close contact with the bottom of the transverse groove 2, so as to avoid the slider 5 from rotating and deviating when it moves outside the double-acting screw 4. The movement of the slider 5 drives the two U-shaped straightening plates 6 to move closer to each other until the outer wall of the web of the U-shaped straightening plate 6 is in close contact with the H-beam 14. The U-shaped straightening plate 6 is used to press the deformed part, so that the web of the H-beam 14 is restored to verticality and flatness, achieving the straightening effect. The first electric telescopic rod 8 is started by the switch. The first electric telescopic rod 8 drives the straightening cross plate 9 to move towards the flange of the H-beam that needs to be straightened, so as to press the flange of the H-beam 14, thereby restoring the flange of the H-beam 14 to verticality and flatness.
