Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, specifically, it relates to a steel structure rolling mechanism. Background Technology

[0002] In the field of steel structure processing, hot rolling is a key forming process used to process steel into the required shapes and sizes.

[0003] Currently, existing hot rolling mills for steel structures lack effective components for removing oxide scale and other impurities from the surface of steel components during hot rolling operations. As a result, these impurities are easily pressed into the steel surface during the rolling process. Once these impurities are pressed in, defects such as pitting and dents will inevitably appear on the steel surface. This not only seriously affects the appearance quality of the steel, reducing its applicability in applications with high surface quality requirements, such as building decoration and machinery manufacturing, but may also lead to a decrease in the protective performance of the steel surface and accelerate the corrosion of the steel.

[0004] Secondly, the presence of impurities may cause uneven stress on the steel surface during rolling. Because the hardness and distribution of impurities differ from those of the steel matrix, the deformation of the impurity area under rolling force is inconsistent with that of the surrounding steel, resulting in uneven steel thickness. This affects the dimensional accuracy of the product. For some steel structural components with strict dimensional accuracy requirements, such as bridges and key components in large mechanical equipment, this uneven thickness may affect the stability and reliability of the entire structure, increase the difficulty of subsequent processing and assembly, and may even lead to product defects, resulting in resource waste and increased costs. Therefore, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a steel structure rolling mechanism that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a steel structure rolling mechanism, including a fixed frame, and further including: a first rolling roller, rotatably connected to the fixed frame; a first motor, fixedly connected to one side of the fixed frame, and its output end fixedly connected to the end of the first rolling roller; a second rolling roller used in conjunction with the first rolling roller, rotatably connected to the fixed frame and located above the first rolling roller; a heat insulation shell, with the fixed frame fixedly installed at the discharge port of the heat insulation shell; a mounting frame, disposed inside the heat insulation shell; support columns, symmetrically slidably connected to the heat insulation shell, with one end of the support column located inside the heat insulation shell fixedly connected to the mounting frame; two sets of cleaning brushes, symmetrically fixedly connected to the inner wall of the mounting frame; a drive mechanism for driving the mounting frame to reciprocate, installed on the heat insulation shell; and an annular jet pipe, fixedly connected to one side of the inner wall of the heat insulation shell, with two sets of jet heads symmetrically connected to the annular jet pipe, the jet heads located on both sides of the mounting frame;

[0007] An air pump connected to the annular jet pipe is fixedly installed on the insulation shell, with the air pump's suction end located inside the insulation shell.

[0008] Furthermore, symmetrical grooves are provided on the upper ends of both sides of the fixed frame, and sliders are slidably connected in the grooves. The second calendering roller is rotatably connected between the two sliders. A threaded rod is vertically rotatably connected in the grooves, and the slider is threadedly connected to the threaded rod. A drive box for driving the threaded rod to rotate is installed at the upper end of the fixed frame.

[0009] Furthermore, the driving mechanism includes a rotating rod, a second motor, an eccentric wheel, and a tension spring. The rotating rod is rotatably connected to the side of the insulation shell near the air pump via a support plate. The second motor is fixedly connected to one of the support plates, and its output end is fixedly connected to one end of the rotating rod. The eccentric wheel is fixedly connected to the rotating rod and slides against the adjacent support column. A fixed plate is fixedly connected to the end of the support column away from the eccentric wheel. The tension spring is sleeved on the support column away from the eccentric wheel, and its two ends are fixedly connected to the insulation shell and the fixed plate, respectively.

[0010] To facilitate smoother reciprocating movement of the mounting frame via the eccentric wheel, an arc-shaped groove is provided at the end of the support column adjacent to the eccentric wheel, and a ball bearing that abuts against the eccentric wheel is movably connected within the arc-shaped groove.

[0011] To facilitate more thorough cleaning of impurities such as oxide scale, multiple mounting frames are provided at equal intervals.

[0012] To facilitate the flow of fallen oxide scale and other impurities for easier cleaning, a flow guide plate is fixedly connected to the lower interior of the insulation shell.

[0013] To facilitate the removal of scale and other impurities from the steel structure, the fixing frame and insulation shell are further inclined downwards from one side of the annular jet pipe to the other.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention can effectively remove impurities such as oxide scale on the surface of steel structural parts through the synergistic effect of cleaning brushes and air jets, avoiding the adverse effects of impurities on the surface quality and dimensional accuracy of steel during the rolling process, and significantly improving the appearance quality and dimensional accuracy of steel.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] Example 1:

[0024] Reference Figures 1-4 A steel structure rolling mechanism includes a fixed frame 1, and further includes: a first rolling roller 101 rotatably connected to the fixed frame 1; a first motor 103 fixedly connected to one side of the fixed frame 1, with its output end fixedly connected to the end of the first rolling roller 101; a second rolling roller 102 used in conjunction with the first rolling roller 101, rotatably connected to the fixed frame 1 and located above the first rolling roller 101; an insulation shell 2, with the fixed frame 1 fixedly installed at the discharge port of the insulation shell 2; a mounting frame 202 disposed inside the insulation shell 2; and support columns 203 symmetrically and slidably connected to the insulation shell 2. One end of the support column 203 located inside the insulation shell 2 is fixedly connected to the mounting frame 202; two sets of cleaning brushes 204 are symmetrically fixedly connected to the inner wall of the mounting frame 202; a drive mechanism for driving the mounting frame 202 to reciprocate is installed on the insulation shell 2; an annular jet pipe 3 is fixedly connected to one side of the inner wall of the insulation shell 2, and two sets of jet heads 301 are symmetrically connected to the annular jet pipe 3, with the jet heads 301 located on both sides of the mounting frame 202; an air pump 302 connected to the annular jet pipe 3 is fixedly installed on the insulation shell 2, and the air pump 302's suction end is located inside the insulation shell 2.

[0025] The fixed frame 1 has symmetrical grooves 104 on both sides of its upper end. A slider 105 is slidably connected in the groove 104. The second calendering roller 102 is rotatably connected between the two sliders 105. A threaded rod 106 is vertically rotatably connected in the groove 104. The slider 105 is threadedly connected to the threaded rod 106. A drive box 107 for driving the threaded rod 106 to rotate is installed at the upper end of the fixed frame 1.

[0026] The drive mechanism includes a rotating rod 205, a second motor 206, an eccentric wheel 207, and a tension spring 209. The rotating rod 205 is rotatably connected to the side of the insulation shell 2 near the air pump 302 via a support plate. The second motor 206 is fixedly connected to one of the support plates, and its output end is fixedly connected to one end of the rotating rod 205. The eccentric wheel 207 is fixedly connected to the rotating rod 205 and slides against the adjacent support column 203. A fixed plate 208 is fixedly connected to the end of the support column 203 away from the eccentric wheel 207. The tension spring 209 is sleeved on the support column 203 away from the eccentric wheel 207, and its two ends are fixedly connected to the insulation shell 2 and the fixed plate 208, respectively.

[0027] The first motor 103 is fixedly connected to one side of the fixed frame 1. When the first motor 103 is powered on and started, the stator and rotor inside it interact to generate rotational power. This power is directly transmitted to the end of the first calendering roller 101 through the output end of the motor, causing the first calendering roller 101 to start rotating on the fixed frame 1. The second calendering roller 102 is rotatably connected to the fixed frame 1 and located above the first calendering roller 101. The steel structure to be calendered passes through the gap between the first calendering roller 101 and the second calendering roller 102. Driven by the rotation of the first calendering roller 101, the steel structure is subjected to the squeezing force of the upper and lower calendering rollers. Within the plastic deformation range of the steel, the thickness of the steel structure gradually decreases, while the length and width directions will correspondingly extend and change, thereby achieving the purpose of calendering and forming.

[0028] The second motor 206 in the drive mechanism is fixedly connected to a support plate on one side of the insulation shell 2. When the second motor 206 starts, its output end drives the rotating rod 205 to rotate around the rotating connection point on the support plate. The eccentric wheel 207, which is fixedly connected to the rotating rod 205, rotates together with the rotating rod 205. Since the geometric center of the eccentric wheel 207 does not coincide with the rotation center, during the rotation, the eccentric wheel 207 will continuously contact the adjacent support column 203 and apply a thrust, thus creating a tension spring. With the cooperation of the spring 209, the support column 203 slides back and forth on the insulation shell 2 along the set sliding direction. Because one end of the support column 203 located inside the insulation shell 2 is fixedly connected to the mounting frame 202, the mounting frame 202 will move back and forth as the support column 203 slides. The two sets of cleaning brushes 204 symmetrically fixedly connected on the inner wall of the mounting frame 202 will sweep back and forth on the surface of the steel structure under the drive of the mounting frame 202, brushing off the oxide scale and other impurities attached to the surface of the steel structure.

[0029] The air pump 302 is fixedly installed on the insulation shell 2, with its suction end located inside the insulation shell 2. When the air pump 302 is working, it draws in the air from inside the insulation shell 2 through the suction end. After being compressed and processed by the air pump 302, the air is delivered to the annular jet pipe 3 connected to the air pump 302. Two sets of jet heads 301 symmetrically connected to the annular jet pipe 3 are located on both sides of the mounting frame 202. Compressed air is ejected from the jet heads 301 at a certain pressure and angle, forming a high-speed airflow to blow away the impurities remaining on the surface of the steel structure.

[0030] The drive box 107 is installed on the upper end of the fixed frame 1. When it is necessary to adjust the distance between the first calendering roller 101 and the second calendering roller 102, the drive box 107 is started. The drive box 107 usually contains components such as a motor and transmission gears. The power generated by the motor after starting is transmitted to the threaded rod 106 through the transmission mechanism such as the transmission gears, so that the threaded rod 106 rotates vertically in the slide groove 104 of the fixed frame 1. A slider 105 is slidably connected in the slide groove 104. The slider 105 is threadedly connected to the threaded rod 106. When the threaded rod 106 rotates, due to the action of the thread, the slider 105 will move vertically in the slide groove 104 along the axial direction of the threaded rod 106. Since the second calendering roller 102 is rotatably connected between the two sliders 105, the vertical position of the second calendering roller 102 will change as the slider 105 moves, thereby realizing the adjustment of the distance between it and the first calendering roller 101 to adapt to the calendering processing requirements of steel structural parts of different thicknesses.

[0031] The insulation shell 2 fixes the fixing frame 1 at its discharge port. The insulation shell 2 is usually made of materials with good thermal insulation properties, such as thermal insulation rock wool, polyurethane foam, etc. Before the steel structure is hot rolled, the insulation shell 2 can prevent the heat exchange between the steel structure and the external environment to a certain extent, reduce the heat loss of the steel structure, and keep the steel structure at a high temperature level. This ensures that the steel structure still has good plasticity and low deformation resistance when it enters the rolling roll for rolling operation, which is conducive to the smooth progress of hot rolling operation and improves the quality and efficiency of rolling processing.

[0032] Existing rolling mills lack impurity removal components, which easily cause impurities to be pressed into the steel surface during hot rolling of steel structural parts, resulting in defects such as pitting and dents, affecting appearance quality. Furthermore, uneven stress on the steel surface leads to uneven thickness and affects dimensional accuracy. This steel structural rolling mill, through the synergistic action of components such as the cleaning brush 204 and the air jet head 301, effectively removes oxide scale and other impurities from the surface of the steel structural parts, avoiding the adverse effects of impurities on the surface quality and dimensional accuracy of the steel during the rolling process. This significantly improves the appearance quality and dimensional accuracy of the steel. Simultaneously, the insulation shell 2 helps maintain the temperature of the steel structural parts, ensuring the stability and processing quality of the hot rolling operation.

[0033] Example 2:

[0034] Reference Figures 1-4 A steel structure rolling mechanism is basically the same as that in Embodiment 1, but further: the end of the support column 203 adjacent to the eccentric wheel 207 is provided with an arc-shaped groove, and a ball bearing 2010 that abuts against the eccentric wheel 207 is movably connected in the arc-shaped groove.

[0035] By setting the ball bearing 2010, the sliding connection between the eccentric wheel 207 and the support column 203 can be converted into a rolling connection, which makes it easier to reduce the friction between the eccentric wheel 207 and the support column 203, so that the eccentric wheel 207 can drive the mounting frame 202 to reciprocate more smoothly.

[0036] Example 3:

[0037] Reference Figures 1-4 A steel structure rolling mechanism, basically the same as in Embodiment 2, but with the following further feature: multiple mounting frames 202 are equidistantly arranged, such as... Figure 3 As shown, by equidistantly setting multiple mounting frames 202 inside the insulation shell 2, the oxide scale and other impurities on the surface of the steel structure can be cleaned more thoroughly, effectively ensuring the cleaning efficiency of the surface impurities.

[0038] A guide plate 201 is fixedly connected to the lower end of the interior of the insulation shell 2. The guide plate 201 can guide the falling oxide scale and other impurities, making it easier to clean them.

[0039] The fixed frame 1 and the insulation shell 2 gradually tilt downwards from one side of the annular jet pipe 3 to the other side. By making the fixed frame 1 and the insulation shell 2 gradually tilt downwards from one side of the annular jet pipe 3 to the other side, the steel structural components moving inside the insulation shell 2 can be distributed at an angle. This allows the oxide scale and other impurities that are swept off to leave the steel structural components better when the annular jet pipe 3 sprays gas onto the surface of the steel structural components through the jet head 301, further improving the thoroughness of cleaning impurities from the steel structural components.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
