Description

Technical Field

[0001] This utility model relates to the field of rolling mill processing technology, specifically a mill guide groove device that facilitates the conveying of rolling mill parts. Background Technology

[0002] Rolling is the core process in metal rolling production. Essentially, it involves applying pressure to metal billets using rotating rolls in a rolling mill, causing plastic deformation to obtain finished or semi-finished products with specific dimensions, shapes, and properties. This process spans multiple stages, including hot rolling, cold rolling, and finish rolling. It is a crucial step in transforming raw billets into industrial materials and a significant factor in determining the final properties of the metal. The conveying of rolled parts is extremely critical in rolling production. This includes guide troughs, which act as guides, ensuring the rolled parts accurately enter the next rolling stage. In hot rolling, for small-sized products, to meet requirements for dimensional accuracy, surface quality, and mechanical properties, the "spinning mill" operation is often used. A spinning mill refers to temporarily discontinuing some intermediate mills when rolling small-sized products, retaining only the key stands to complete the rolling task, thereby reducing deformation resistance and controlling product dimensions.

[0003] However, the existing guide chute devices between rolling mills still have certain shortcomings. While the scrambling mill can solve the process problems of small-specification rolling, it easily leads to a significant increase in the span between rolling mills. The existing guide chute devices only have a single guiding function. Because the scrambling mill causes the span between rolling mills to be too large, small-specification products are difficult to convey and bite into during normal rolling, resulting in a "slippage" phenomenon. This leads to insufficient friction between the rolled piece and the rolls, causing relative sliding between the rolled piece surface and the rolls. This not only aggravates roll wear but may also cause local overheating of the rolled piece due to the high temperature generated by the slippage, resulting in scrap. If the slippage lasts for too long, the rolled piece will accumulate at the rolling mill inlet, which may also cause equipment collision accidents and threaten the safety of operators.

[0004] To address this issue, this invention provides a mill guide chute device that facilitates the transport of rolled parts, thus solving the problem of poor feeding of hot steel to the next mill due to the large span when producing small-scale rolling mills. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mill guide chute device that facilitates the transport of rolled products, thus solving the aforementioned problems.

[0007] Preferably, a fixing frame is fixedly connected to the top of the base, and a motor is fixedly installed on the top of the fixing frame. The motor is located on the side of the guide groove body.

[0008] Preferably, the motor's power shaft is fixedly connected to a coupling via a bearing, and the side of the coupling extends into the drive cavity and is fixedly connected to a first conveying roller.

[0011] Preferably, the interior of both the first and second conveying rollers is hollow, and the exterior of both the first and second conveying rollers is covered with a wear-resistant ceramic layer, the thickness of which is set to 3-5 mm.

[0012] Beneficial effects This invention provides a mill guide chute device that facilitates the transport of rolled products. Compared with the prior art, it has the following advantages: (1) A mill guide trough device that facilitates the conveying of rolled parts, by adding a first conveying roller, a second conveying roller, a sprocket, a coupling and a motor in the middle position of the guide trough body, an automatic conveying structure is formed in the guide trough. During production, the roller table can be started to rotate to convey the rolled parts, reducing the resistance during conveying, effectively reducing the occurrence of accidents caused by the large span between mills, and the chain drive has high transmission accuracy, which can save time and improve work efficiency.

[0013] (2) A mill guide chute device that facilitates the conveying of rolled parts. By improving the structure of the first conveying roller and the second conveying roller, friction loss can be reduced.

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 protection scope of the present utility model.

[0017] Example 1: Please see Figure 1-4 A mill guide chute device for facilitating the transport of rolled products includes a base 1. A support seat 8 is fixedly connected to the top of the base 1 by fixing bolts. A guide chute body 9 is fixedly connected to the top of the support seat 8. Two drive cavities 10 are symmetrically arranged on the inner wall of the guide chute body 9. The sides of the two drive cavities 10 are fixedly connected to the inner wall of the guide chute body 9. Several sets of second conveying rollers 6 are arranged between the two drive cavities 10. Both sides of the several sets of second conveying rollers 6 extend into the drive cavities 10. A fixing frame 2 is fixedly connected to the top of the base 1, and a motor 3 is fixedly installed on the top of the fixing frame 2. The motor 3 is located on the side of the guide groove body 9. The power shaft of motor 3 is fixedly connected to coupling 4 via bearings. The side of coupling 4 extends into drive cavity 10 and is fixedly connected to first conveying roller 5. The first conveying roller 5 extends into the drive cavities 10 on both sides, and the first conveying roller 5 and the second conveying roller 6 are driven by a sprocket 7. The support base 8 and the guide groove body 9 are fixed by welding. The side of the guide groove body 9 is provided with a guide part with an inclination angle of 30 degrees.

[0018] In this embodiment, during the conveying process, the motor 3 drives the coupling 4 to rotate, which in turn drives the first conveying roller 5 to rotate. The first conveying roller 5 and the second conveying roller 6 are driven by a sprocket 7, forming a conveying roller track within the guide trough body 9. This allows the roller track to be activated during production to convey the rolled workpiece, reducing resistance during conveying and effectively reducing accidents caused by excessive span between rolling mills. Furthermore, the transmission between the first conveying roller 5 and the second conveying roller 6 via the sprocket 7 provides high transmission accuracy, saves time, and improves work efficiency. The main body of 9 is made of high-strength wear-resistant steel, and its inner wall is coated with tungsten carbide. The thickness of the tungsten carbide coating ensures that the guide groove body 9 has both high strength and wear resistance. The motor 3 is a Siemens / ABB variable frequency speed control motor. The power range and speed range of the motor 3 are 0-150rpm and 5-15kW, respectively, which can realize stepless speed regulation and meet the adjustment needs under different conditions. The motor 3 is controlled by PLC. The coupling 4 is a flexible gear coupling, which can compensate for installation errors. The maximum torque of the coupling 4 is ≥5000N·m, which can enhance transmission stability.

[0019] Example 2: Please see Figure 2-5 This embodiment provides a technical solution based on embodiment one: the interior of the first conveying roller 5 and the second conveying roller 6 are both hollow, and the exterior of the first conveying roller 5 and the second conveying roller 6 are both covered with a wear-resistant ceramic layer, the thickness of which is set to 3-5mm.

[0020] In this embodiment, by improving the structure of the first conveying roller 5 and the second conveying roller 6, friction loss can be reduced. The hollow design inside the roller body of the first conveying roller 5 and the second conveying roller 6 can reduce the weight and reduce the load on the motor 3. The weight reduction of the roller body can make the contact pressure distribution of the roller gap more uniform, effectively avoiding adhesive wear caused by local overload. In addition, the wear-resistant ceramic layer covering the outside of the roller body can also reduce friction loss.
