Description

Technical Field

[0001] This utility model relates to the field of short stress line rolling mill technology, specifically a self-aligning block for a bearing seat of a short stress line finishing rolling mill. Background Technology

[0002] In modern bar and wire rod production, short-stress-line finishing mills, with their advantages of high precision and high stability, have become the core and key equipment in bar and wire rod production lines. Their performance directly affects the quality and production efficiency of bar and wire rod products. To optimize the stress state of the bearing housings of short-stress-line finishing mills and reduce equipment wear and precision degradation caused by uneven stress, self-aligning block structures are typically installed on the operating side bearing housings.

[0003] Traditional self-aligning block structures for bearing housings in short-stress-line finishing mills have several drawbacks. Firstly, the mating self-aligning blocks in the original structure are all floating blocks. This design makes it difficult to fix the position of the ball center on the concave-convex surface relative to the operating side bearing housing, resulting in a significant deviation between the actual stress state and the theoretical setting. This prevents the full utilization of the self-aligning block's performance advantages and affects the overall operating accuracy of the equipment. Secondly, the clamping screws in the original structure are specially made parts with complex shapes. Not only are their manufacturing processes cumbersome and costly, but they also lack versatility. Once damaged, replacement is difficult and time-consuming, severely impacting equipment maintenance efficiency and production continuity. Therefore, those skilled in the art have provided a self-aligning block for bearing housings in short-stress-line finishing mills to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a self-aligning block for a bearing housing of a short stress line finishing mill, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-aligning block for a bearing housing of a short-stress-line finishing mill, comprising:

[0007] An operating side bearing housing is provided with an outer concave self-aligning block and an outer convex self-aligning block that are arranged opposite to each other on the outer side of the operating side bearing housing. An inner concave self-aligning block and an inner convex self-aligning block that are arranged opposite to each other are also provided on the outer side of the operating side bearing housing. The outer concave self-aligning block and the outer convex self-aligning block are all mounted on the operating side bearing housing with self-made screws.

[0008] Both the outer convex self-aligning block and the inner concave self-aligning block are provided with spacers, and the self-made screw is provided with a washer, and the washer is in contact with the spacer.

[0009] The operating side bearing seat is mounted on the frame, and the self-made screw is connected to the frame;

[0010] The operating side bearing housing is equipped with a lubrication mechanism.

[0011] Preferably, both the outer convex self-aligning block and the inner concave self-aligning block are provided with positioning pins, and the operating side bearing seat is provided with positioning holes, and the positioning pins are engaged in the positioning holes.

[0012] Preferably, the outer concave self-aligning block, the outer convex self-aligning block, the inner concave self-aligning block, and the inner convex self-aligning block are all novel composite materials, and the outer concave self-aligning block, the outer convex self-aligning block, the inner concave self-aligning block, and the inner convex self-aligning block are all provided with reinforcing ribs.

[0013] Preferably, the refueling mechanism includes a refueling pipe, a micro pump, a flow control valve, and a fuel tank. The fuel tank is mounted on the operating side bearing seat. One end of the refueling pipe passes through the operating side bearing seat, the outer convex self-aligning block, and the inner concave self-aligning block, and the other end of the refueling pipe is connected to the fuel tank. The micro pump and the flow control valve are mounted on the refueling pipe.

[0014] Preferably, the oil tank is equipped with a liquid level sensor, the oil tank is provided with an oil inlet pipe, and a cover is installed on the oil inlet pipe.

[0016] Preferably, a PLC controller is installed on the operating side bearing housing, and the PLC controller is electrically connected to the micro pump, flow control valve, liquid level sensor, ceramic piezoresistive pressure sensor and distance sensor respectively.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model adopts a structure combining fixed blocks and floating blocks. Spacers are installed on the outer convex self-aligning block and the inner concave self-aligning block, and are fixed by washers and screws, ensuring that the center position of the spheres on the convex and concave surfaces is fixed relative to the operating side bearing seat. Compared with the traditional fully floating block structure, this design effectively avoids the problem of sphere center position offset, ensures that the actual stress state highly matches the theoretical setting, fully utilizes the performance advantages of the self-aligning blocks, significantly improves the overall operating accuracy of the short stress line finishing mill, reduces equipment wear caused by uneven stress, and extends the service life of the equipment.

[0019] 2. This utility model uses standard parts and simple components as substitutes. Standard parts are easy to procure, have stable quality, and are reasonably priced; the spacer, as a simple self-made component with a regular shape, is easy to manufacture. This improvement significantly reduces the manufacturing complexity and production cost of the self-aligning block. At the same time, the use of standard parts greatly improves the versatility of the parts, allowing for quick replacement when the self-aligning block is damaged, significantly shortening equipment maintenance time, ensuring production continuity, and reducing economic losses caused by equipment failure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1-3 This utility model provides a technical solution:

[0026] A self-aligning block for a bearing housing of a short-stress-line finishing mill, comprising:

[0027] The operating side bearing housing 6 has an outer concave self-aligning block 1 and an outer convex self-aligning block 3 installed on its outer side, and an inner concave self-aligning block 4 and an inner convex self-aligning block 5 installed on its outer side. The outer concave self-aligning block 1 and the outer convex self-aligning block 3, as well as the inner concave self-aligning block 4 and the inner convex self-aligning block 5, are all installed on the operating side bearing housing 6 by self-made screws 2.

[0028] Spacers 8 are provided on both the outer convex self-aligning block 3 and the inner concave self-aligning block 4. Washers 9 are provided on the self-made screw 2, and the washers 9 are in contact with the spacers 8.

[0029] The operating side bearing seat 6 is mounted on the frame 7, and the self-made screw 2 is connected to the frame 7;

[0030] Furthermore, both the outer convex self-aligning block 3 and the inner concave self-aligning block 4 are provided with positioning pins 10, and the operating side bearing seat 6 is provided with positioning holes 11. The positioning pins 10 are engaged in the positioning holes 11. Ceramic piezoresistive pressure sensors 20 are installed between the outer concave self-aligning block 1 and the outer convex self-aligning block 3 and between the inner concave self-aligning block 4 and the inner convex self-aligning block 5. Distance sensors 21 are installed on both the outer concave self-aligning block 1 and the inner convex self-aligning block 5.

[0031] The outer convex self-aligning block 3 and the inner concave self-aligning block 4, installed on the operating side bearing housing 6, are fixed by a spacer 8, a washer 9, and a self-made screw 2. Simultaneously, a locating pin 10 engages with a locating hole 11 on the operating side bearing housing 6. This dual fixing method ensures the precise and stable positioning of these two fixed blocks, thus determining the position of the center of the concave and convex surfaces. The outer concave self-aligning block 1 and the inner convex self-aligning block 5 are floating blocks. When the operating side bearing housing 6 is subjected to rolling force and undergoes elastic deformation, the floating self-aligning blocks slide on the concave and convex surfaces that cooperate with the fixed self-aligning blocks. Utilizing the large contact surface, the self-aligning function is achieved, ensuring that the bearing housing maintains good operating accuracy even under stress.

[0032] Ceramic piezoresistive pressure sensors 20, installed between the outer concave self-aligning block 1 and the outer convex self-aligning block 3, and between the inner concave self-aligning block 4 and the inner convex self-aligning block 5, can monitor the pressure distribution and changes on the contact surfaces of the self-aligning blocks in real time. When the self-aligning blocks experience relative sliding or uneven force under the action of rolling force, the pressure sensors convert the pressure signal into an electrical signal and transmit it to the PLC controller 22. Simultaneously, distance sensors 21 installed on the outer concave self-aligning block 1 and the inner convex self-aligning block 5 can detect the sliding displacement of the floating blocks in real time and feed the displacement data back to the PLC controller 22. Through these sensors, the system can comprehensively grasp the working status of the self-aligning blocks, providing data support for equipment operation.

[0033] Based on the above embodiments, the outer concave self-aligning block 1 and the outer convex self-aligning block 3, as well as the inner concave self-aligning block 4 and the inner convex self-aligning block 5, are all made of novel composite materials, and the outer concave self-aligning block 1 and the outer convex self-aligning block 3, as well as the inner concave self-aligning block 4 and the inner convex self-aligning block 5, are all provided with reinforcing ribs 12.

[0034] The outer concave self-aligning block 1, the outer convex self-aligning block 3, the inner concave self-aligning block 4, and the inner convex self-aligning block 5 are all made of a new type of composite material. This material has high strength, high wear resistance, and good fatigue resistance, and can effectively resist mechanical stress and frictional wear during the rolling process. The reinforcing ribs 12 set on the self-aligning blocks further enhance the structural strength, improve the load-bearing capacity of the self-aligning blocks, reduce the risk of deformation under complex stress conditions, extend the service life of the self-aligning blocks, and ensure the long-term stable operation of the equipment.

[0035] The operating side bearing housing 6 is equipped with a refueling mechanism, which includes a refueling pipe 13, a micro pump 14, a flow control valve 15, and an oil tank 16. The oil tank 16 is installed on the operating side bearing housing 6. One end of the refueling pipe 13 passes through the operating side bearing housing 6, the outer convex self-aligning block 3, and the inner concave self-aligning block 4, and the other end of the refueling pipe 13 is connected to the oil tank 16. The micro pump 14 and the flow control valve 15 are installed on the refueling pipe 13. A liquid level sensor 17 is installed on the oil tank 16. An oil inlet pipe 18 is provided on the oil tank 16, and a baffle 19 is installed on the oil inlet pipe 18.

[0036] The lubrication mechanism on the operating side bearing housing 6 achieves intelligent lubrication under the coordination of the PLC controller 22. The oil tank 16 stores lubricating oil. When the system is running, the PLC controller 22 determines the working status and lubrication requirements of the self-aligning block based on data from the pressure sensor and distance sensor 21. If increased force or frequent sliding displacement of the self-aligning block is detected, the PLC controller 22 controls the micro pump 14 to start and precisely adjusts the lubricating oil delivery rate through the flow control valve 15, ensuring the lubricating oil is delivered to the contact area of ​​the self-aligning block via the lubrication pipe 13. The level sensor 17 on the oil tank 16 monitors the oil level in real time. When the oil level is lower than the set value, it sends a signal to the PLC controller 22, reminding the operator to replenish the lubricating oil in time to ensure the continuous and stable operation of the lubrication system.

[0037] In the above embodiment, a PLC controller 22 is installed on the operating side bearing seat 6. The PLC controller 22 is electrically connected to the micro pump 14, the flow control valve 15, the liquid level sensor 17, the ceramic piezoresistive pressure sensor 20, and the distance sensor 21.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
