Description

Technical Field

[0001] The utility model relates to a rolling roller, in particular to a rolling roller which is easy to disassemble and replace, belonging to the technical field of rolling rollers. Background Art

[0002] Rollers are components on a rolling mill that cause the rolled metal to undergo plastic deformation. They are installed and disassembled to correspond to the rolling mill and perform corresponding tasks. Generally, two or more rollers are arranged in parallel to meet different usage requirements. However, existing rollers are prone to surface wear during use. When worn, the rollers need to be replaced regularly. If they are replaced as a whole, the cost of use increases, and it is not convenient to quickly replace rollers of different patterns or sizes.

[0003] A replaceable roller disclosed in the Chinese patent application publication specification CN213968311U includes a roller body, a mounting shaft is provided at both left and right ends of the roller body, and a first roller sleeve is provided on the outside of the roller body, a fixing piece is provided on the outside of the first roller sleeve, a mounting bolt is connected through the inside of the limiting hole, and a second roller sleeve is also provided on the outside of the roller body, the mounting shaft and the roller body are in an integrated structure, the inner diameter of the first roller sleeve is equal to the inner diameter of the second roller sleeve, and the first roller sleeve and the second roller sleeve are both nested and connected with the roller body, and the length of the first roller sleeve and the second roller sleeve is smaller than the length of the roller body. The replaceable roller facilitates the replacement of different types of roller sleeves on the outer surface of the roller body through the first roller sleeve and the second roller sleeve, thereby realizing the replaceability of the roller, and the stability of the installation of the first roller sleeve and the second roller sleeve can be ensured through the fixing piece.

[0004] During the use of the above patent, the roller sleeve needs multiple installation bolts to be fixed. The installation and removal process of multiple installation bolts is relatively cumbersome and requires workers to perform repeated operations many times, which not only increases the complexity of the operation, but also may increase the risk of operational errors. For this reason, we provide a replaceable roller to solve the above problem. Utility Model Content

[0025] See also Figure 1 to Figure 4 The embodiment of the utility model provides a replaceable roller that is easy to disassemble, including a roller body 3 and a roller sleeve 5. The interior of the roller body 3 is provided with a mounting assembly 1 for mounting and fixing the roller sleeve 5. The interior of the roller body 3 is provided with an adjusting assembly 2 for adjusting the contraction movement of the mounting assembly 1. The mounting assembly 1 includes a plurality of mounting grooves 102 opened inside the roller body 3. A fixed plug 101 is slidably installed inside each mounting groove 102. The top end of each fixed plug 101 penetrates the roller body 3 and extends to the outside of the roller body 3. A return spring 103 is fixed to the inner wall of each mounting groove 102. The bottom end of each return spring 103 is connected to the outer surface of the fixed plug 101.

[0026] Please refer to Figure 1 and Figure 2The adjusting component 2 includes a cavity 205 opened inside the roller body 3, and a threaded rod 203 is rotatably connected inside the cavity 205. A notch 202 is opened on the outer surface of the roller body 3. The right end of the threaded rod 203 passes through the cavity 205 and extends to the inside of the notch 202. A rotating block 201 is fixed to the left end of the threaded rod 203. A moving block 204 is threadedly connected to the outer surface of the threaded rod 203. The outer surface of the moving block 204 is slidably connected to the inner wall of the cavity 205 through a supporting slider. The supporting slider can provide support for the moving block 204, making it more stable during operation. The rotation of the rotating block 201 drives the moving block 204 to move inside the cavity 205 through the threaded rod 203, thereby squeezing the fixed plug 101, causing it to telescope on the outer surface of the roller body 3, thereby realizing rapid fixing and release of the roller sleeve 5.

[0027] Please refer to Figure 1 , Figure 3 and Figure 4 A plurality of positioning sliders 4 are fixed to the outer surface of the roller body 3, a sliding groove 6 adapted to the outer surface of the roller body 3 is provided inside the roller sleeve 5, a plurality of positioning grooves 8 adapted to the positioning slider 4 are provided inside the roller sleeve 5, the outer surface of the positioning slider 4 is slidably connected to the inside of the positioning groove 8, the outer surface of the roller body 3 is slidably connected to the inner wall of the sliding groove 6, a plurality of fixing grooves 7 adapted to the fixing plug 101 are provided inside the roller sleeve 5, and the correct alignment and stable connection between the roller body 3 and the roller sleeve 5 are ensured through the coordinated use of the positioning slider 4 and the positioning groove 8, thereby enhancing the connection stability between the roller body 3 and the roller sleeve 5, reducing the possible misalignment or looseness during the rolling process, and improving the rolling accuracy and safety.

[0028] When the utility model is used, firstly, the prepared roller body 3 is installed inside the roller sleeve 5 through the cooperation of the positioning slider 4 and the positioning slide groove 8. This ensures the correct position and stability of the roller body 3. The rotating block 201 is rotated. The rotation of the rotating block 201 drives the threaded rod 203 to rotate, and then drives the moving block 204 to move left and right inside the cavity 205, so that the moving block 204 squeezes the fixed plug block 101 while moving, so that the fixed plug block 101 makes a telescopic movement on the outer surface of the roller body 3, and the fixed plug block 101 is completely inserted into the interior of the fixed groove 7, thereby achieving the fixation of the roller body 3. When disassembly is required, the moving block 204 is driven back to the original position by the rotating block 201 again, and the fixed plug block 101 is driven to reset to the interior of the roller body 3 by the reset spring 103. The contraction of the fixed plug block 101 causes it to withdraw from the fixed groove 7, thereby unlocking the roller body 3. Finally, the roller body 3 is taken out from the interior of the roller sleeve 5 to complete the disassembly process, which not only simplifies the installation and disassembly process of the roller, but also improves the convenience and safety of the operation. The installation and disassembly can be achieved through a single operation of the rotating block 201, which greatly reduces the operation steps and the required time.
