[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Refer to Figures 1-4 , an embodiment provided by the present invention: an I-beam bending device, including a base 1, a bracket 2 fixedly connected to the top of the base 1, an installation shell 3 fixedly connected to the inner side of the bracket 2, a cavity 4 opened inside the installation shell 3, a first motor 5 fixedly connected to the inside of the cavity 4, a gear 6 fixedly connected to the output end of the first motor 5, slide grooves 7 opened on both sides of the cavity 4, a rack 9 slidably connected to the inside of the slide grooves 7, a slide block 10 fixedly connected to the top of the rack 9, a connecting plate 11 fixedly connected to the top of the slide block 10, a clamping plate 12 fixedly connected to the top of the connecting plate 11, two telescopic rods 13 fixedly connected to the outside of the connecting plate 11, a hydraulic cylinder 22 fixedly connected to the top of the base 1, a roller 8 fixedly connected to the output end of the hydraulic cylinder 22, and a positioning component installed on the top of the base 1, and the positioning component is used for positioning the I-beam.

[0026] Specifically, the base 1 serves as the foundation of the entire device, firmly supporting the entire system. The bracket 2 fixedly installs the mounting shell 3 above the base 1 through a fixed connection. The cavity 4 opened inside the mounting shell 3 provides an installation space for the first motor 5. Through the drive of the first motor 5, the linear motion of the rack 9 is realized. This meshing connection has the characteristics of high precision and high reliability, and can ensure the accuracy of the rack 9 during movement. The slider 10 slides in the chute 7 to ensure the smoothness of the rack 9 during movement. At the same time, one end of the connecting plate 11 is driven by the slider 10, so that the movement of the rack 9 can be directly transmitted to the clamping plate 12. The telescopic rod 13 provides necessary support and stability when the clamping plate 12 clamps the I-beam, preventing tilting or shaking due to uneven force. The hydraulic cylinder 22 drives the roller 8 to move, so that the I-beam can move along a predetermined trajectory during the bending process, improving the bending accuracy and efficiency.

[0027] Referring to Figures 2-5 , the positioning assembly includes a support column 14. A second motor 15 is fixedly connected to the outside of the support column 14. The output end of the second motor 15 is fixedly connected to a bidirectional lead screw 16. A threaded sleeve 17 is threadedly connected to the outside of the bidirectional lead screw 16. A rotating column 18 is rotatably connected to the inside of the threaded sleeve 17. One end of the rotating column 18 is rotatably connected to a movable block 19. A slide bar 20 is slidably connected to the inside of the movable block 19. A spring 21 is fixedly connected to the outside of the rotating column 18.

[0028] Specifically, the output end of the bidirectional lead screw 16 is fixedly connected. When the second motor 15 rotates, when the bidirectional lead screw 16 rotates, the threaded sleeve 17 will move along the axial direction of the bidirectional lead screw 16 and drive the rotating column 18 to move, so that the distance between the two rotating columns 18 can be expanded. At the same time, the slide bar 20 provides a stable sliding track for the movable block 19 to ensure the linearity and stability of the movable block 19 during movement.

[0029] Referring to Figures 3-4 , the slider 10 is slidably connected to the outside of the mounting shell 3. The top of the base 1 is fixedly connected with a movable groove 24. A slide plate 23 is slidably connected to the inside of the movable groove 24. The external corresponding positions of the gear 6 are meshed with the outside of the two racks 9. The outside of the telescopic rod 13 is installed on the outside of the mounting shell 3. The outside of the telescopic rod 13 is installed on the outside of the mounting shell 3.

[0030] Specifically, the movable groove 24 provides a sliding track for the slide plate 23, so that the roller 8 is pushed by the hydraulic cylinder 22, and the slide plate 23 slides along the movable groove 24. The telescopic rod 13 provides stability for the clamping plate 12 to prevent the clamping mechanism from tilting or shaking during movement or clamping.

[0031] Referring to Figures 1-5, a limiting groove is provided inside the support column 14, the outside of the threaded sleeve 17 is slidably connected inside the limiting groove, the top of the base 1 is fixedly connected with a frame 25, both ends of the slide bar 20 are fixedly connected inside the frame 25, one end of the hydraulic cylinder 22 is fixedly connected with a delivery pipe, the top of the base 1 is fixedly connected with an oil tank, and the other end of the delivery pipe is fixedly connected to the outside of the oil tank.

[0032] Specifically, when the threaded sleeve 17 moves driven by the bidirectional lead screw 16, it will move along the track of the limiting groove. The slide bar 20 provides a stable sliding track for the movable block 19. When the hydraulic cylinder 22 works, it will suck hydraulic oil from the oil tank through the delivery pipe and generate pressure inside to drive the roller 8 to bend the I-beam.

[0033] Working principle: First, place the I-beam on the base 1 and accurately position it through the positioning component to ensure the accuracy of the bending process. Then start the first motor 5. Through the meshing transmission of the gear 6 and the rack 9, the clamping plate 12 moves towards the I-beam, and with the support of the telescopic rod 13, the I-beam is firmly clamped between the clamping plates 12. After the clamping plate 12 clamps the I-beam, start the hydraulic cylinder 22, and its output end pushes the roller 8 to move until the roller 8 contacts the I-beam. Then, through the continuous force application of the hydraulic cylinder 22, the roller 8 rolls along the length direction of the I-beam, and at the same time, the clamping plate 12 gradually moves driven by the gear 6 and the rack 9, so as to realize the bending of the I-beam. When the I-beam is bent to the required angle or shape, stop the force application of the hydraulic cylinder 22, and control the first motor 5 to release the clamping of the I-beam by the clamping plate 12, and then take out the bent I-beam;

[0034] When positioning the I-beam is required, start the second motor 15, drive the bidirectional lead screw 16 to rotate through its output end. The rotation of the bidirectional lead screw 16 drives the threaded sleeve 17 to move along its axis direction, and then drives the movement of the rotating column 18, so that the movable block 19 moves along the slide bar 20. After the bending is completed, the second motor 15 can rotate in the reverse direction, driving the bidirectional lead screw 16 and the threaded sleeve 17 to move in the reverse direction, so that the movable block 19 returns to the initial position.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
