Description

Technical Field

[0001] This utility model relates to the field of cooling bed rollers, specifically a medium-thick plate cooling bed roller. Background Technology

[0002] The cooling bed rollers are key components of the cooling bed system, used in metal sheet or bar rolling production lines to transport and cool rolled products. Taking a roller-type cooling bed as an example, it consists of multiple roller shafts, each individually controlled by a motor. A certain number of rollers are mounted on the roller shafts, and the movement of the rollers pushes the steel sheet to move, thus achieving the transport and cooling of the sheet.

[0003] During use, cooling bed rollers wear out quickly and require frequent replacement due to direct contact with the idler rollers. Existing patent application number CN202321191642.5 discloses a cooling bed roller in which the outer cylindrical component is detachably connected to the roller body. When the cooling bed roller is damaged, it can be disassembled and replaced by replacing the outer cylindrical component, greatly reducing the difficulty of replacement. However, the outer cylindrical plate requires multiple sets of fasteners to be fixed to the outer edge of the roller, making installation cumbersome. Furthermore, the outer cylindrical plate is prone to loosening during use, affecting the normal conveying of the sheet material. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a medium-thick plate cooling bed roller disc to solve the problem of wear and replacement of the cooling bed roller disc.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A medium-thick plate cooling bed roller disc includes a roller disc body, and a plurality of outer circular plates are connected to the outer edge of the roller disc body by a locking mechanism;

[0007] The locking mechanism includes a bolt rod, a connecting shell, a circular plate, a disc spring, a connecting sleeve, and a locking nut. The bolt rod is installed at the center of the bottom of the outer circular plate. The connecting shell is fitted onto the bolt rod and is a detachable mechanism. The circular plate is installed at the top inside the connecting shell. The disc spring is installed at the bottom inside the connecting shell. The connecting sleeve is movably inserted into the bottom of the connecting shell, and its upper end is connected to the disc spring. The locking nut is suspended on the bolt rod.

[0008] Furthermore, the outer edge of the roller disc body has a number of strip-shaped holes that correspond to the bolt rods.

[0009] Furthermore, the bottom of the circular plate is equipped with several positioning rods that intersect with the disc-shaped springs.

[0010] Furthermore, the center of the disc-shaped spring is convex downwards.

[0011] Furthermore, the connecting shell, the circular plate, the disc spring, and the connecting sleeve each have a circular hole at their center corresponding to the bolt rod.

[0012] Furthermore, anti-slip grooves are evenly distributed on the outer surfaces of several outer circular plates.

[0013] This utility model provides a medium-thick plate cooling bed roller, which has the following advantages: by installing several outer circular plates on the outer edge of the roller body, direct contact between the roller body and the support roller is avoided, reducing roller wear. The several outer circular plates are fixed on the outer edge of the roller body by a locking mechanism. When locking, the locking nut compresses the disc spring through the connecting sleeve, causing deformation and generating elastic force, which pushes the locking nut in the opposite direction, so as to achieve a tight fit between the locking nut and the bolt rod, achieving the purpose of preventing loosening, and facilitating the installation or replacement of the outer circular plates.

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Please see Figures 1 to 6As shown, this application embodiment provides a medium-thick plate cooling bed roller, including a roller body 1. Several outer circular plates 2 are connected to the outer edge of the roller body 1 by a locking mechanism. The locking mechanism includes a bolt rod 3, a connecting shell 4, a circular plate 5, a disc spring 6, a connecting sleeve 7, and a locking nut 8. The bolt rod 3 is installed at the bottom center of the outer circular plate 2. The connecting shell 4 is fitted on the bolt rod 3 and is a detachable mechanism. The circular plate 5 is installed at the top inside the connecting shell 4. The disc spring 6 is installed at the bottom inside the connecting shell 4. The connecting sleeve 7 is movably inserted into the bottom of the connecting shell 4 and its upper end is connected to the disc spring 6. The locking nut 8 is suspended on the bolt rod 3.

[0023] In this embodiment, by installing several outer circular plates 2 on the outer edge of the roller body 1, direct contact between the roller body 1 and the idler roller is avoided, reducing roller wear. The several outer circular plates 2 are respectively fixed on the outer edge of the roller body 1 by a locking mechanism. When locking, firstly, the connecting shell 4 is fitted onto the bolt rod 3, and then the locking nut 8 is tightened. During the tightening process, the locking nut 8 deforms by being squeezed by the connecting sleeve 7. The disc spring 6 generates elastic force, which pushes the locking nut 8 in the opposite direction, so that the locking nut 8 and the bolt rod 3 are tightly fitted, achieving the purpose of preventing loosening. When the outer circular plates 2 are replaced, the locking nut 8 and the connecting shell 4 can be removed in sequence, which is convenient for replacement.

[0024] In some embodiments, a plurality of strip-shaped holes 9 corresponding to bolt rods 3 are uniformly opened on the outer edge of the roller body 1, and a plurality of round holes are uniformly opened on the roller body 1, with the strip-shaped holes 9 communicating with the round holes, such as... Figure 1 As shown, this facilitates the insertion and tightening of bolt rod 3.

[0025] In some embodiments, the bottom of the circular plate 5 is equipped with a plurality of positioning rods 10 that intersect with the disc-shaped spring 6, such as... Figure 4 As shown, the positioning rod 10 can prevent the disc spring 6 from becoming misaligned.

[0026] In some embodiments, in conjunction with the appendix Figure 3 As shown, the center of the disc spring 6 initially bulges downwards.

[0027] In some embodiments, the connecting shell 4, the circular plate 5, the disc spring 6, and the connecting sleeve 7 are each provided with a circular hole 11 corresponding to the bolt rod 3, so that the bolt rod 3 can pass through the connecting shell 4.

[0028] In some embodiments, anti-slip grooves 12 are evenly formed on the outer surfaces of several outer circular plates 2 to increase friction and facilitate the conveying of medium-thick plates.

[0029] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
