Description

Technical Field

[0001] This utility model relates to the field of hot-rolled steel processing technology, and in particular to an anti-tilting device for hot-rolled low-carbon steel strip for cold forming. Background Technology

[0002] In the production process of a hot rolling production line, after the steel strip is rolled, it needs to be transferred by a conveying device. However, when the steel strip is sent out of the equipment, it often tilts upwards. If this is not controlled, it can easily damage the equipment itself. Moreover, once the tilting occurs, the steel strip itself will be squeezed and deformed, resulting in scrap steel, reducing the yield and increasing production costs.

[0003] Therefore, in view of the above situation, there is an urgent need to develop an anti-warping device for hot-rolled low-carbon steel strips used for cold forming, so as to overcome the shortcomings in current practical applications. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide an anti-warping device for hot-rolled low-carbon steel strip for cold forming, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An anti-tilting device for hot-rolled low-carbon steel strip for cold forming includes two support plates. Each support plate has an arc-shaped groove, within which a slider is slidably connected. A connecting plate is fixedly connected to the upper end of each support plate. A first hydraulic telescopic rod is rotatably mounted between the connecting plate and the slider. A first rotating rod is rotatably connected to the side of each slider that is close to it. A receiving plate is fixedly connected to the other end of each first rotating rod. Multiple evenly distributed fixing rods are fixedly connected between the two receiving plates. A roller is rotatably sleeved on the outer wall of each fixing rod. A second rotating rod is also fixedly connected to the other end of each receiving plate. A second hydraulic telescopic rod is rotatably connected to the other end of each second rotating rod, and the other end of the second hydraulic telescopic rod is rotatably connected to the support plate. Each support plate has a mating groove that engages with the corresponding second rotating rod. A positioning component is also fitted onto one of the support plates.

[0006] In a further technical solution, limit grooves are provided on both sides of the inner wall of the arc-shaped groove, and limit blocks are slidably connected to the inner walls of the limit grooves, and the limit blocks are fixedly connected to the slider.

[0007] In a further technical solution, an opening groove is also provided on the support plate.

[0008] In a further technical solution, the arc-shaped groove is arc-shaped, and its center is at the same center position as the center of the mating groove.

[0009] In a further technical solution, the positioning component includes a receiving plate, a receiving groove, and a ranging device; the receiving plate is fixedly connected to the upper end of one of the support plates, the receiving plate has multiple receiving grooves, the inner wall of each receiving groove is fixedly connected to a ranging device, and the projection of the ranging device in the vertical direction falls on the upper end surface of the receiving plate.

[0010] A further technical solution also includes a controller, which is electrically connected to the ranging device, the second hydraulic telescopic rod, and the first hydraulic telescopic rod.

[0011] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art: 1. After the steel strip is produced on the hot rolling production line, it is transported out by the conveying mechanism. Then, the first hydraulic telescopic rod is controlled to extend. The first hydraulic telescopic rod pushes the slider to slide along the inner wall of the arc groove. The slider drives the receiving plate and roller to rotate and descend along the axis of the second rotating rod through the first rotating rod until the roller at this end abuts the steel strip. Then, the second hydraulic telescopic rod is controlled to retract. The second hydraulic telescopic rod drives the second rotating rod to rotate around the axis of the first rotating rod. The second rotating rod drives the receiving plate and multiple rollers to rotate around the axis of the first rotating rod until the receiving plate is in a horizontal state. Thus, the steel strip is flattened by multiple receiving plates, thereby preventing the steel strip from curling up during passage. 2. The first hydraulic telescopic rod pushes the slider to slide along the inner wall of the arc groove. The slider drives the receiving plate and roller to rotate and descend along the axis of the second rotating rod through the first rotating rod, thereby adjusting the gap between the slider and the conveying mechanism, so as to adapt to steel strips of different thicknesses.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] like Figures 1-3 As shown in the figure, this utility model embodiment provides an anti-tilting device for hot-rolled low-carbon steel strip for cold forming, including two support plates 1, which are fixedly connected to the ground. Each support plate 1 has an arc-shaped groove 2, and a slider 4 is slidably connected within each arc-shaped groove 2. A connecting plate 12 is fixedly connected to the upper end of each support plate 1. A first hydraulic telescopic rod 15 is rotatably connected between the connecting plate 12 and the slider 4. A first rotating rod 6 is rotatably connected to the side of each slider 4 that is close to each other. The other end of each first rotating rod 6 is fixedly connected to a bearing. The receiving plate 7 has multiple evenly distributed fixed rods (not shown in the figure) fixedly connected between the two receiving plates 7. The outer wall of the fixed rod is rotatably sleeved with a roller 10. The other end of each receiving plate 7 is also fixedly connected with a second rotating rod 9. The other end of each second rotating rod 9 is rotatably connected with a second hydraulic telescopic rod 11. The other end of the second hydraulic telescopic rod 11 is rotatably connected to the support plate 1. Each support plate 1 has a mating groove 8, which is engaged with the corresponding second rotating rod 9. One of the support plates 1 is also fitted with a positioning component 13.

[0018] Furthermore, limit grooves 3 are provided on both sides of the inner wall of the arc-shaped groove 2, and limit blocks 5 are slidably connected to the inner wall of the limit grooves 3. The limit blocks 5 are fixedly connected to the slider 4. The slider 4 can only slide along the inner wall of the arc-shaped groove 2 by means of the cooperation of the limit grooves 3 and the limit blocks 5.

[0019] Furthermore, the support plate 1 is also provided with an opening groove 14, which effectively avoids collision and interference between the second rotating rod 9 and the support plate 1 during the rotation and descent process.

[0020] Furthermore, the arc-shaped groove 2 is arc-shaped, and its center is at the same center position as the center of the mating groove 8.

[0021] like Figure 1 and Figure 3As shown, the positioning assembly 13 includes a receiving plate 131, a receiving groove 132, and a ranging device 133; the upper end of one of the support plates 1 is fixedly connected to the receiving plate 131, the receiving plate 131 is provided with a plurality of receiving grooves 132, the inner wall of each receiving groove 132 is fixedly connected to a ranging device 133, and the projection of the ranging device 133 in the vertical direction falls on the upper surface of the receiving plate 7.

[0022] In practical applications, the distance between the receiving plate 131 and different positions on the receiving plate 7 is measured by multiple receiving slots 132, thereby identifying the angular position of the receiving plate 7 and the roller 10.

[0023] Furthermore, it also includes a controller, which is electrically connected to the ranging device 133, the second hydraulic telescopic rod 11, and the first hydraulic telescopic rod 15, respectively.

[0024] In this embodiment of the invention, after the steel strip is produced on the hot rolling production line, it is transported out by a conveying mechanism. Then, the first hydraulic telescopic rod 15 is controlled to extend, pushing the slider 4 to slide along the inner wall of the arc-shaped groove 2. The slider 4 drives the receiving plate 7 and the roller 10 to rotate and descend along the axis of the second rotating rod 9 via the first rotating rod 6 until the roller 10 at that end abuts the steel strip. Subsequently, the second hydraulic telescopic rod 11 is controlled to retract, driving the second rotating rod 9 to rotate around the axis of the first rotating rod 6. The second rotating rod 9 drives the receiving plate 7 and multiple rollers 10 to rotate around the axis of the first rotating rod 6 until the steel strip is fully extended. The positioning component 13 identifies that the receiving plate 7 is in a horizontal state, thereby flattening the steel strip through multiple receiving plates 7, thus preventing the steel strip from tilting upwards during passage; the first hydraulic telescopic rod 15 pushes the slider 4 to slide along the inner wall of the arc groove 2, and the slider 4 drives the receiving plate 7 and the roller 10 to rotate and descend along the axis of the second rotating rod 9 through the first rotating rod 6, thereby adjusting the gap between the roller 10 and the conveying mechanism, so as to adapt to steel strips of different thicknesses; when the roller 10 needs to be reset, the second hydraulic telescopic rod 11 is first controlled to reset, the second hydraulic telescopic rod 11 drives the second rotating rod 9 to engage in the mating groove 8, and then the first hydraulic telescopic rod 15 is controlled to reset.
