Description

Technical Field

[0001] This application relates to the field of steel production technology, and more specifically, to an axial adjustment mechanism for the eccentric sleeve of a wire rod roller box. Background Technology

[0002] The eccentric sleeve in the wire rod roll box is a key component. By rotating or moving the eccentric sleeve axially, the gap or centering position of the rolls can be finely adjusted, thereby improving the dimensional accuracy and quality of the rolled products.

[0003] During the production of high-speed wire rod mills, the wear of the eccentric sleeve keyway and sliding key will increase the gap between them, which will not be able to guarantee the accuracy of the axial positioning of the eccentric sleeve of the roll box. The eccentric sleeve and sliding key must be replaced frequently, which will affect the production rhythm and is time-consuming and labor-intensive, and cannot meet the production needs. Utility Model Content

[0004] The purpose of this application is to provide an axial adjustment mechanism for the eccentric sleeve of a wire rod roller box, which reduces wear on the sliding key and the eccentric sleeve keyway by increasing the contact area between the sliding key and the keyway, thereby extending the service life of the component and reducing the frequency of maintenance.

[0005] This application provides an axial adjustment mechanism for the eccentric sleeve of a wire rod roller box, which adopts the following technical solution:

[0006] An axial adjustment mechanism for an eccentric sleeve of a wire rod roller box includes a support member, an adjustment assembly, and a sliding key. The support member is disposed outside the roller box. The adjustment assembly includes a connector, a rotating member, and a locking member. The connector is installed inside the roller box hole. The rotating member is installed on the support member and is fixedly connected to the connector. The locking member is used to lock the rotation of the rotating member.

[0007] The connector is provided with an eccentric groove, one end of the sliding key is rotatably installed in the eccentric groove, and the other end of the sliding key is set in the eccentric keyway. The end of the sliding key near the eccentric keyway is a rectangular structure.

[0008] Preferably, the rotating component includes an adjusting bolt and a positioning block. The adjusting bolt is mounted on the support component, and the positioning block is provided with a guide groove. The head of the adjusting bolt is located inside the guide groove. The positioning block is fixedly connected to the connecting component. One end of the positioning block abuts against the roller box, and the other end of the positioning block abuts against the support component.

[0009] Preferably, the tail of the adjusting bolt has a quadrilateral or hexagonal structure.

[0010] Preferably, the positioning block and the connecting member are fixed together by connecting bolts.

[0011] Preferably, the locking element is a nut.

[0012] Preferably, the support includes a locking plate and a plurality of locking bolts, the locking plate being mounted on the outside of the roller box by the locking bolts.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] This application increases the contact area between the sliding key and the eccentric sleeve keyway by designing the end of the sliding key near the eccentric sleeve keyway as a rectangular structure, thereby reducing the wear of the sliding key and the eccentric sleeve keyway, extending the service life of the sliding key and the eccentric sleeve, reducing the frequency of maintenance and the labor intensity of workers, and saving spare parts costs. In addition, the rectangular structure design at the end of the sliding key also increases the axial adjustment eccentricity, thereby increasing the axial adjustment range of the roller box eccentric sleeve.

[0025] Example

[0026] like Figure 1 As shown in the embodiment of this application, the axial adjustment mechanism for the eccentric sleeve of the wire rod roller box includes a support member 1, an adjustment component 2, and a sliding key 3. The support member 1 is disposed outside the roller box 4. The adjustment component 2 includes a connector 5, a rotating component 6, and a locking component 7. The connector 5 is installed inside the roller box hole 8. The rotating component 6 is installed on the support member 1 and is fixedly connected to the connector 5. The locking component 7 is used to lock the rotation of the rotating component 6.

[0027] The connector 5 is provided with an eccentric groove 9. One end of the sliding key 3 is rotatably installed in the eccentric groove 9, and the other end of the sliding key 3 is set in the eccentric sleeve keyway 11. The end of the sliding key 3 near the eccentric sleeve keyway 11 has a rectangular structure. The rectangular structure design at the end of the sliding key 3 can increase the contact area between the sliding key 3 and the eccentric sleeve keyway 11, reduce the wear between the sliding key 3 and the eccentric sleeve keyway 11, extend the service life of the sliding key 3 and the eccentric sleeve 10, reduce the frequency of maintenance and the labor intensity of workers, and save spare parts costs. In addition, the rectangular structure design at the end of the sliding key 3 also increases the axial adjustment eccentricity, increasing the axial adjustment range of the roller box eccentric sleeve.

[0028] In use, under the action of external tools such as wrenches, the rotating part 6 drives the connecting part 5 to rotate, and the connecting part 5 drives the sliding key 3 to rotate. Due to the design of the eccentric structure, the height of the sliding key 3 changes, and the sliding key 3 drives the position of the eccentric sleeve 10 to change, thereby realizing the adjustment of the axial position of the eccentric sleeve 10 of the roller box 4. After the adjustment is completed, the rotation of the rotating part 6 can be locked by using the locking part 7.

[0029] In this embodiment, the rotating component 6 includes an adjusting bolt 12 and a positioning block 13. The adjusting bolt 12 is installed on the support component 1, and the positioning block 13 is provided with a guide groove 14. The head of the adjusting bolt 12 is located inside the guide groove 14. The positioning block 13 is fixedly connected to the connecting component 5. One end of the positioning block 13 abuts against the roller box 4, and the other end of the positioning block 13 abuts against the support component 1.

[0030] In use, rotating the adjusting bolt 12 causes the relative position of the adjusting bolt 12 on the support 1 to change slowly due to the threaded connection, thereby improving the adjustment accuracy. The rotation of the adjusting bolt 12 will drive the positioning block 13 to rotate. Under the combined limiting action of the roller box 4 and the support 1, the positioning block 13 will only rotate and will not shift, ensuring the overall performance.

[0031] In this embodiment, to facilitate the turning of the adjusting bolt 12 with external tools such as wrenches, the tail of the adjusting bolt 12 is designed as a quadrilateral or hexagonal structure.

[0032] In this embodiment, the positioning block 13 and the connector 5 are fixed together by connecting bolts 15. Using connecting bolts 15 to fix them together makes it easy to disassemble and assemble the positioning block 13 and the connector 5.

[0033] In this embodiment, the locking element 7 is a nut.

[0034] In this embodiment, the support member 1 includes a locking plate 16 and a plurality of locking bolts 17. The locking plate 16 is installed on the outside of the roller box 4 by locking bolts. The locking plate 16 is used to support the rotating member 6 and ensure the performance of the rotating member 6.

[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
