Description

Technical Field

[0001] This utility model relates to the field of auxiliary pushing in H-beam flange straightening machines, specifically an auxiliary pushing structure for H-beam flange straightening machines. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually assembled with welds, bolts or rivets. When processing steel structures, straightening machines are often used to straighten the flanges of H-beam steel structures.

[0003] In the prior art, such as in CN215391729U, an H-beam flange straightening machine for steel structure processing is disclosed. It includes a base, a transmission roller is provided at one end of the upper side of the base, and a motor for controlling the rotation of the transmission roller is provided on one side of the base. Side plates are fixedly connected to both ends of the upper side of the base. Straightening components are provided on opposite sides of the two side plates in a mirror arrangement. Connecting plates are fixedly connected to the middle of both sides of the straightening components. Support frames are fixedly connected to the ends of the two connecting plates that are far apart and to the middle of the surface of the straightening components. Auxiliary straightening rollers are rotatably connected to the middle of the support frames. A crossbeam is fixedly connected to the upper side of the two side plates, and a downward straightening roller is provided in the middle of the lower side of the crossbeam.

[0004] While the aforementioned patent achieves limiting support at both ends of the H-beam structure, preventing displacement during rotation and improving the straightening quality of the H-beam flanges, the method of adjusting the height of the limiting support inside the grooves on both sides of the H-beam through adjustment holes has certain limitations. The spacing between the adjustment holes affects the adjustment range, and when the height of the H-beam is in the middle of the adjustment holes, the adjustment holes cannot be adjusted. Therefore, to address the above problems, an auxiliary pushing structure for the H-beam flange straightening machine is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the height of the limiting support inside the grooves on both sides of the H-beam is adjusted by adjusting the holes, which has certain limitations. The spacing between the adjusting holes affects the adjustment range. When the height of the H-beam is in the middle of the adjusting holes, the adjusting holes cannot be adjusted. This utility model proposes an auxiliary pushing structure for an H-beam flange straightening machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The auxiliary pushing structure of the H-shaped steel flange straightening machine of this utility model includes a U-shaped frame; support plates are fixedly connected to the bottom of both sides of the U-shaped frame; threaded rods are threaded through the middle of both sides of the U-shaped frame; a longitudinal fixing rod is fixedly connected to one end of the threaded rod; a sliding groove is opened on the surface of the longitudinal fixing rod; positive and negative threaded rods are arranged inside the sliding groove; a slider A is arranged on one side of the surface of the positive and negative threaded rods; a slider B is arranged on the surface of slider A and slider B; a fixed shaft is arranged on the surface of the fixed shaft; a roller is movably connected to the surface of the fixed shaft; a knob is arranged at the top of the longitudinal fixing rod; the bottom of the knob passes through the top of the longitudinal fixing rod and is fixedly connected to the positive and negative threaded rods.

[0007] Preferably, a plurality of rollers are equidistantly arranged on the side of the support plate from left to right, and a transmission mechanism is provided on the other side of the support plate. The transmission mechanism is connected to the rollers via a transmission rod.

[0008] Preferably, the inner wall of the slide is provided with a wear-resistant coating, the depth of the slide is 1 / 3 of the height of the longitudinal fixing rod, and guide flanges are provided on both sides.

[0009] Preferably, the surface of the roller is covered with an elastic rubber layer, the thickness of which gradually decreases from the center of the roller to both ends, and anti-slip grooves are formed on the surface.

[0010] Preferably, the threaded sections of the positive and negative threaded rods are divided into left and right helical directions, the internal thread helical directions of slider A and slider B match the corresponding threaded sections, and ball bearings are provided on the bottom surface of the sliders.

[0012] The advantages of this utility model are:

[0013] 1. This utility model achieves the adaptive adjustment function of H-shaped steel groove height through the linkage design of positive and negative threaded rods and sliders A and B. Rotating the knob drives the positive and negative threaded rods to rotate, causing sliders A and B to move in opposite directions along the groove, driving the roller to synchronously fit the inner top and inner bottom surfaces of the H-shaped steel groove.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1-4 As shown, an auxiliary pushing structure for an H-shaped steel flange straightening machine includes a U-shaped frame 1; support plates 2 are fixedly connected to the bottom of both sides of the U-shaped frame 1; threaded rods 3 are threaded through the middle of both sides of the U-shaped frame 1; one end of the threaded rod 3 is fixedly connected to a longitudinal fixing rod 4; a groove 5 is opened on the surface of the longitudinal fixing rod 4; positive and negative threaded rods 6 are arranged inside the groove 5; an A slider 7 is arranged on one side of the surface of the positive and negative threaded rods 6; a B slider 8 is arranged on the other side; a fixed shaft 9 is arranged on the surface of the A slider 7 and the B slider 8; a roller 10 is movably connected to the surface of the fixed shaft 9; a knob 11 is arranged at the top of the longitudinal fixing rod 4; the bottom of the knob 11 passes through the top of the longitudinal fixing rod 4 and is fixedly connected to the positive and negative threaded rods 6.

[0023] During operation, when adjusting the width of the H-beam, rotating the threaded rods 3 on both sides of the U-shaped frame 1 pushes the longitudinal fixing rod 4 to move laterally to the groove position; when adjusting the height, rotating the knob 11 drives the positive and negative threaded rods 6 to rotate, and the A slider 7 and B slider 8 move in opposite directions along the slide groove 5, causing the roller 10 to synchronously fit the inner top and inner bottom surfaces of the H-beam groove, realizing adaptive adjustment of width and height. The positive and negative threaded rods 6 and the sliders work together to achieve bidirectional clamping, adapting to the height and width of different specifications of H-beams, significantly improving adjustment flexibility and stability.

[0024] Furthermore, several rollers 12 are equidistantly arranged on the side of the support plate 2 from left to right, and a transmission mechanism 13 is provided on the other side of the support plate 2. The transmission mechanism 13 is connected to the rollers 12 through a transmission rod.

[0025] During operation, the transmission mechanism 13 drives the idler roller 12 to rotate synchronously through the transmission rod. The H-beam is placed on the surface of the idler roller 12, and the V-shaped guide groove guides the H-beam to be transported smoothly along the axial direction to avoid deviation. The idler roller 12 cooperates in the transmission to improve the conveying efficiency, and the guide groove structure enhances the stability of the straight conveying of the H-beam and optimizes the correction quality.

[0026] Furthermore, the inner wall of the slide groove 5 is provided with a wear-resistant coating, the depth of the slide groove 5 is 1 / 3 of the height of the longitudinal fixing rod 4, and guide flanges are provided on both sides;

[0027] During operation, the wear-resistant coating on the inner wall of the slide groove 5 reduces the sliding friction resistance of the slider, and the guide flange restricts the lateral displacement of the slider, ensuring that the slider moves accurately along the axis of the slide groove 5. The combination of the wear-resistant coating and the guide flange extends the service life of the slide groove 5, significantly improves the smoothness of adjustment, and enhances the durability of the equipment.

[0028] Furthermore, the surface of the roller 10 is covered with an elastic rubber layer, the thickness of which gradually decreases from the center of the roller 10 to both ends, and anti-slip grooves are opened on the surface.

[0029] During operation, the elastic rubber layer on the surface of roller 10 adapts to the curvature of the H-beam groove, the anti-slip groove increases the contact friction, and the elastic deformation fits the curved surface upon contact. The elastic rubber layer buffers the impact force, the anti-slip groove prevents conveying deviation, and the H-beam surface remains undamaged, significantly improving protection.

[0030] Furthermore, the threaded sections of the positive and negative threaded rod 6 are divided into left and right helical directions, and the internal thread helical directions of slider A 7 and slider B 8 match the corresponding threaded sections, and ball bearings are provided on the bottom surface of the sliders.

[0031] During operation, the left-hand and right-hand sections of the positive and negative threaded rod 6 drive slider A 7 and slider B 8 to move in opposite directions, respectively. The ball bearing reduces the frictional resistance between the slider and the groove 5. The manual rotation of the knob 11 makes operation easier. The left and right threads enable bidirectional synchronous adjustment of the slider. The ball bearing reduces the operating torque, thus optimizing adjustment efficiency and convenience.

[0032] Furthermore, the axis of the idler roller 12 is parallel to the bottom surface of the U-shaped frame 1, and a V-shaped guide groove is provided on the surface of the idler roller 12 with wear-resistant rubber strips pasted inside the groove;

[0033] During operation, the V-shaped guide groove of the idler roller 12 guides the H-beam flange to position, the wear-resistant rubber strip inside the groove reduces surface wear and improves the durability of the idler roller 12, the V-shaped guide groove ensures accurate positioning of the H-beam, the wear-resistant rubber strip extends the service life of the idler roller 12, and the maintenance cost is significantly reduced.

[0034] Working principle: The threaded rods 3 on both sides of the rotating U-shaped frame 1 push the longitudinal fixed rod 4 to move laterally to adapt to the width of the H-beam. Rotating the knob 11 drives the positive and negative threaded rods 6 to rotate, causing slider A 7 and slider B 8 to move in opposite directions along the slide groove 5, which drives the roller 10 to clamp the inner top and inner bottom surfaces of the H-beam groove. The elastic rubber layer fits the curved surface of the anti-slip groove. The roller 12 drives the H-beam to be smoothly conveyed along the V-shaped guide groove through the transmission mechanism 13. The wear-resistant coating and guide flange ensure the smooth adjustment of the slider, realizing the adaptive clamping and stable pushing of the H-beam size.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
