Description

Technical Field

[0001] This application belongs to the field of high-speed wire rod production technology, and particularly relates to a cantilevered rolling element device. Background Technology

[0002] In the production process of high-speed wire rod, the function of the soaking section is to release the internal temperature of the rolled piece to the surface, making the internal and external temperatures of the rolled piece more uniform. The soaking section is equipped with multiple soaking guide grooves 1, and the rolled piece 2 runs within the guide groove holes 11 of the soaking guide grooves 1. If the rolled piece 2 scrapes against the bottom of the guide groove hole 11 during operation, it can easily lead to quality accidents such as scratches.

[0003] To reduce scratches and improve the quality of the rolled piece 2, built-in rolling heat conduction grooves are generally installed at intervals between the heat-conducting grooves 1, such as... Figure 1 and Figure 2 As shown, the guide groove 41 on the heat conduction groove 4 (shown in cross-section for ease of display) is opposite to the homogenizing guide groove 1, facilitating the movement of the rolled piece. The guide roller 3 is rotatably connected to the heat conduction groove 4 via a bearing. The guide roller 3, with its surface higher than the heat conduction groove 41, limits the vertical movement of the rolled piece 2 and converts the sliding friction with the bottom wall of the guide groove hole 11 into rolling friction, reducing scratches. However, because the bearing is built into the guide roller 3, a large amount of heat is transferred to the guide roller 3 and the bearing when the high-temperature rolled piece 2 passes through the guide roller 3. To ensure normal bearing rotation, oil-air lubrication and cooling water must be connected through the grease nipple 5 for cooling. The bottom wall of the guide roller is generally in contact with the cooling water. When the rolled piece passes through the guide roller, it inevitably becomes contaminated with oil and water stains, further contaminating the diameter gauge (used to measure the diameter and roundness of the rolled piece) and the heat exchanger 6 (used to intercept defects such as knots and scratches) arranged between the guide grooves, affecting the normal operation of the equipment. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this application provides a cantilevered rolling element device that can prevent contamination of the rolled workpiece by cooling water and oil vapor.

[0005] To achieve the above objectives, the technical solution provided in this application is as follows:

[0006] This application provides a cantilevered rolling element device arranged in a heat-conducting groove, including a support base. A mounting shaft is rotatably connected to the support base via a bearing. A cantilevered guide roller is provided at the end of the mounting shaft. An arc-shaped groove is formed on the cantilevered guide roller for guiding the rolled workpiece. The bearing is sealed on the side facing the cantilevered guide roller. An oil nozzle is provided on the support base for adding lubricating oil to the bearing.

[0007] Optionally, the bearing includes a single-sided sealed bearing, wherein the inner ring of the single-sided sealed bearing is connected to the mounting shaft, the outer ring is connected to the support seat, and the oil nozzle is connected to the interior of the single-sided sealed bearing.

[0008] Optionally, the arc-shaped groove is opposite to the guide hole of the heat-spreading groove; the support seat is arranged on the outside of the heat-spreading groove along the direction perpendicular to the movement of the rolled piece.

[0009] Optionally, the mounting shaft is fixedly connected to the cantilever guide roller.

[0010] Optionally, the end of the mounting shaft away from the cantilever guide roller passes through the support seat and is threadedly connected to the nut, and a washer is fitted on the mounting shaft between the nut and the support seat.

[0011] Optionally, it also includes a heat-conducting groove, on which a guide groove is provided opposite to the guide groove hole, and an installation groove is provided on the heat-conducting groove. The cantilever guide roller is arranged in the installation groove, and the upper surface of the cantilever guide roller is higher than the guide groove; the support seat is arranged on the outside of the heat-conducting groove.

[0012] Optionally, it also includes a base, on which both the support and the heat-conducting groove are arranged, and the support is detachably connected to the base by bolts.

[0013] Optionally, the nozzle is arranged on the top wall of the support.

[0014] Compared with the prior art, this application has at least the following beneficial effects:

[0015] This application reduces heat transfer from the high-temperature rolled piece to the bearing by setting up a cantilever guide roller and mounting the bearing on a support seat away from the cantilever guide roller, thereby improving the bearing's service life. The bearing is significantly less heated, eliminating the need for water cooling. The bearing is also sealed away from the cantilever guide roller and towards it, preventing lubricating oil from contacting the rolled piece and reducing contamination of the rolled piece, which in turn reduces contamination of equipment such as the hot-rolling mill. The bearing and the cantilever guide roller are essentially isolated by the sidewall of the mounting groove (except for the space required for the mounting shaft), greatly minimizing contamination of the rolled piece even if oil leakage occurs.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0025] Example 1

[0026] like Figures 3-5 As shown, a cantilever rolling element device is arranged in the heat-conducting groove 1, including a support base 7. A mounting shaft 8 is rotatably connected to the support base 7 via a bearing. The inner ring of the bearing is fixed relative to the mounting shaft 8, and the outer ring of the bearing is fixed relative to the support base 7. A cantilever guide roller 9 is provided at the end of the mounting shaft 8. An arc-shaped groove is provided on the cantilever guide roller 9 for guiding the rolled workpiece 2. The side of the bearing facing the cantilever guide roller 9 is sealed. An oil nozzle 5 is provided on the support base 7 for adding lubricating oil into the bearing.

[0027] In this application, the rolling friction between the cantilever guide roller 9 and the workpiece 2 reduces damage to the workpiece 2. Furthermore, by setting the cantilever guide roller 9, the bearing is placed on the support seat 7 away from the cantilever guide roller 9, which reduces the heat transfer from the high-temperature workpiece 2 to the bearing, improves the service life of the bearing, and greatly reduces the heat received by the bearing, eliminating the need for water cooling. In the prior art, when the bearing leaks, the high-speed rotation of the guide roller will cause lubricating oil to splash and contaminate the workpiece 2 and the guide roller. In this application, the bearing is far away from the cantilever guide roller 9 and is sealed on the side facing the cantilever guide roller 9, thus preventing lubricating oil from contacting the workpiece 2.

[0028] Example 2

[0029] The difference between this embodiment and Embodiment 1 is that the bearing includes a single-sided sealed bearing. The inner ring of the single-sided sealed bearing is connected to the mounting shaft 8, and the outer ring is connected to the support seat 7. The grease nipple 5 is connected to the inside of the single-sided sealed bearing. In this embodiment, the grease nipple 5 is arranged on the top wall of the support seat 7, and lubricating oil is added to the bearing through the grease nipple 5.

[0030] The arc-shaped groove is opposite to the guide hole 11 of the heat-spreading groove 1; along the direction perpendicular to the movement of the workpiece 2, the support seat 7 is arranged on the outside of the heat-spreading groove 1, thereby ensuring that the support seat 7 and the bearing on it are far away from the workpiece 2 and reduce the heat.

[0031] The mounting shaft 8 is fixedly connected to the cantilever guide roller 9. The mounting shaft 8 has a bearing mounting groove 42. One end of the mounting shaft 8, away from the cantilever guide roller 9, passes through the support seat 7 and is threadedly connected to a nut 81. A washer 82 is fitted onto the mounting shaft 8 between the nut 81 and the support seat 7, allowing the cantilever guide roller 9 and the mounting shaft 8 to rotate as a unit, and ensuring the mounting shaft 8 remains stable on the support seat 7.

[0032] The cantilever rolling element device in this embodiment also includes a heat-conducting groove 4, on which a guide groove 41 is formed opposite to the guide groove hole 11. An installation groove 42 is formed on the heat-conducting groove 4. The installation groove 42 is square and has an opening 43 for the installation shaft 8 to pass through. The cantilever guide roller 9 is arranged in the installation groove 42, and the upper surface of the cantilever guide roller 9 is higher than the guide groove 41. The support seat 7 is arranged outside the heat-conducting groove 4. The rolled piece 2 runs on the cantilever guide roller 9, the guide groove 41, and the guide groove hole 11. Because the upper surface of the cantilever guide roller 9 is higher than the guide groove 41, wear on the rolled piece 2 is reduced. In this embodiment, the bearing and the cantilever guide roller 9 are basically blocked by the side wall of the installation groove 42 (except for the space required for the installation of the installation shaft 8), which greatly reduces contamination of the rolled piece 2 even if the bearing leaks oil.

[0033] The cantilevered rolling element device in this embodiment also includes a base 71. The support seat 7 and the heat conduction groove 4 are both arranged on the base 71. The support seat 7 is detachably connected to the base 71 by bolts, which facilitates the maintenance and replacement of the support seat 7.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
