Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal processing technology, specifically to a high-efficiency brush roller adjustment device in aluminum ingot rolling production. Background Technology

[0002] In aluminum ingot rolling production, a cleaning roller is needed to clean aluminum powder from the surface of the work rolls in real time to prevent excessive accumulation of aluminum powder from affecting the rolling process. Each time the work rolls are changed, the cleaning roller needs to be disassembled, reassembled, and readjusted to achieve the appropriate roller pressure to meet production requirements.

[0003] However, during the disassembly of the work roll, radial clearance will exist in the work roll bearing (the maximum single-sided clearance can reach 0.6mm). This causes the work roll in the newly assembled work roll assembly to be in a free state within the bearing housing. In this state, the bearing clearance will cause uneven brush roll pressing (a 0.6mm radial clearance will result in a 9mm reduction in the brush roll pressing area). Adjusting the brush roll pressing under these conditions often results in a discrepancy with the actual production state, leading to inconsistent pressing on the operating side and the transmission side (i.e., the brush roll is not parallel to the work roll in operation).

[0004] Typically, online brush roll adjustment is not possible within the equipment. Existing brush roll adjustment involves pre-adjusting the work roll before feeding it into the mill. A pressure cylinder then presses the work roll against the mill to eliminate all gaps (zeroing operation). During this zeroing process, the work roll is pressed tightly against the bearing to eliminate gaps. The work roll is then pulled out, and the pressure is adjusted a second time. Only then is the pressure between the brush roll and the work roll uniform, achieving a clean, light brushing effect. This process is cumbersome, time-consuming, requires secondary adjustments, is labor-intensive, and inefficient. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a high-efficiency brush roller adjustment device in aluminum ingot rolling production. It eliminates the need for online brush roller adjustment, simplifies operation, shortens adjustment time, improves work efficiency, eliminates the need for secondary adjustment, and greatly reduces the workload of workers. It can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency brush roller adjustment device in aluminum ingot rolling production, comprising a fixed frame, one end of which is hinged to a tilting frame body via a rotary pin, the upper side of which is provided with an L-shaped placement groove for placing a work roller assembly, the end of which is away from the rotary pin and is hinged to a drive device, the drive device comprising a cylinder seat mounted on the fixed frame, a tilting cylinder mounted on the cylinder seat, a pusher fixedly mounted on the top of the movable end of the tilting cylinder, the pusher being hinged to the end of the tilting frame body.

[0007] As a preferred embodiment of this utility model, a steel lining plate is fixedly provided on the surface of the placement groove.

[0008] As a preferred technical solution of this utility model, a positioning pin is provided on the inner surface of the placement slot of the flipping frame.

[0009] As a preferred technical solution of this utility model, the side surface of the fixing frame is provided with a pressing cylinder bracket, and the upper surface of the pressing cylinder bracket is equipped with a brush roller bearing seat pressing cylinder.

[0010] As a preferred technical solution of this utility model, the fixing frame is fixedly connected to the ground foundation by anchor bolts.

[0011] As a preferred embodiment of this utility model, a leveling pad is provided between the fixing frame and the ground foundation.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By placing the upper and lower working roller assemblies in the placement slot of the flipping frame, and then driving the flipping frame and working roller assemblies to rotate and adjust the angle through the drive device, the working roller is pressed against the working roller bearing seat near the brush roller under the action of gravity. Then, the brush roller is driven by the hydraulic motor of the brush roller to eliminate the gap. After the measurement is correct, the limit nut is locked and the flipping frame and upper and lower working roller assemblies are rotated in the opposite direction by the drive device to lift it up. The brush roller adjustment can be completed off-line, without the need for brush roller adjustment on-line. The operation is simple, the adjustment time is shortened, the work efficiency is improved, and the need for secondary adjustment is eliminated, which greatly reduces the workload of the staff.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency brush roller adjustment device in aluminum ingot rolling production, including a fixed frame 1. One end of the fixed frame 1 is hinged to a flipping frame 2 via a rotary pin 4. The upper side of the flipping frame 2 is provided with an L-shaped placement groove for placing work roller assemblies. The end of the flipping frame 2 away from the rotary pin 4 is hinged to a driving device, which can drive the flipping frame 2 to rotate around the rotary pin 4. By placing upper and lower work roller assemblies in the placement groove of the flipping frame 2, and then driving the flipping frame 2 and the work roller assemblies to rotate via the driving device, the angle can be adjusted.

[0017] The driving device includes a cylinder seat 5 mounted on a fixed frame 1, a tilting cylinder 3 mounted on the cylinder seat 5, and a pusher 7 fixedly mounted on the top of the movable end of the tilting cylinder 3. The pusher 7 is hinged to the end of the tilting frame 2. The tilting cylinder 3 can push the tilting frame 2 up and down by 20° through the pusher 7, rotating the placement trough and the upper and lower working roller assemblies to a horizontal hoisting position and an inclined adjustment position.

[0018] The working roller assembly includes a working roller bearing housing 8 and a brush roller bearing housing 10 mounted on the side surface of the working roller bearing housing 8. A working roller 9 is mounted on the working roller bearing housing 8, and a brush roller 11 is mounted on the brush roller bearing housing 10. A fixing frame is also provided on the side surface of the working roller bearing housing 8. A clamping cylinder 12 and a limit nut 13 are respectively provided on the fixing frame for pressing the brush roller 11 against the working roller 9.

[0019] When the tilting cylinder 3 pushes the tilting frame 2 to rotate to a horizontal position and the placement trough is tilted, the working roller 9 presses against the working roller bearing seat 8 near the brush roller 11 under the action of gravity. Then, the brush roller 11 is driven by the hydraulic motor of the brush roller 11 to eliminate the gap. After the measurement is correct, the limit nut 13 is locked and the tilting frame 2 and the upper and lower working roller assemblies are lifted by the reverse rotation of the drive device. The brush roller adjustment can be completed off-line. There is no need to adjust the brush roller on-line. The operation is simple, the adjustment time is shortened, the work efficiency is improved, and the secondary adjustment is not required, which greatly reduces the labor burden of the staff.

[0020] In a preferred embodiment, a steel liner 6 is fixedly provided on the surface of the placement groove to protect the surface of the placement groove and extend the service life of the device.

[0021] In a preferred embodiment, a leveling shim is provided between the fixing frame 1 and the ground foundation, and the fixing frame 1 is fixedly connected to the ground foundation by anchor bolts to prevent the equipment from shifting during use.

[0022] In the preferred embodiment, the tilting frame 2 is a welded structure with sufficient rigidity.

[0023] For adjustments to the upper work roll assembly, please refer to [link / reference]. Figure 3 : (1) Drive the tilting cylinder 3 to extend. After it extends, adjust the tilting frame 2 to be tilted and the placement slot to be horizontal. Hoist the work roll of the roughing mill into the placement slot of the tilting frame 2. Then operate the button to retract the tilting cylinder 3 to the position shown in the figure. The tilting frame 2 is horizontal and the placement slot and work roll assembly are tilted. At this time, the upper liner of the upper work roll bearing seat is tightly attached to the steel liner 6.

[0024] (2) After the upper working roller bearing seat is close to the entire tilting frame 2, the working roller 9 presses against the lower left of the working roller bearing seat 8 under the action of gravity. At this time, connect the external quick-connect oil pipe (operating side and transmission side clamping cylinder, traverse cylinder, hydraulic motor, etc.), put a piece of white paper between the brush roller 11 and the working roller 9, so that the clamping cylinder 12 is clamped. Observe and adjust the limit nut 13 so that the width overlap of the white paper indentation is 25~30mm. Drive the hydraulic motor of the brush roller to eliminate the gap, and then measure the overlap again to be 25~30mm. After the measurement is correct, lock the limit nut 13 and lift the clamping cylinder 12. At this time, the brush roller adjustment is completed. (3) Operate the corresponding control button to extend the tilting cylinder 3 and lift the tilting frame 2 so that the working roll assembly reaches the horizontal (hoisting) position; after the upper working roll device and the lower working roll device are adjusted, they are assembled and put into the rolling mill for production, and the cleaning effect is observed.

[0025] For adjustments to the lower work roll assembly, please refer to [link / reference]. Figure 4 : (1) Extend the tilting cylinder, and after extending it, adjust the tilting frame 2 to be tilted and the placement slot to be horizontal. Place the roughing mill positioning pad (5mm thick) on the steel liner 6 on the operating side of the tilting frame 2, and then hoist the roughing mill lower working roll device onto the placement slot. Then operate the corresponding button to retract the tilting cylinder 3 to reach the position shown in the figure. The tilting frame 2 is horizontal, and the placement slot and working roll assembly are tilted. At this time, the lower working roll bearing seat and the positioning pin are pressed together without gap.

[0026] (2) After the lower working roller bearing seat is close to the tilting frame 2, the working roller 9 presses against the lower left of the working roller bearing seat 8 under the action of gravity. At this time, connect the quick-connect oil pipe (operating side and transmission side clamping cylinder, traverse cylinder, hydraulic motor), put a piece of white paper between the brush roller 11 and the working roller 9, so that the clamping cylinder 12 is clamped. Observe and adjust the limit nut 13 so that the width overlap of the white paper indentation is 25~30mm. Drive the hydraulic motor of the brush roller 13 to eliminate the gap, and then measure the overlap again to be 25~30mm. After the measurement is correct, lock the limit nut 13 and lift the clamping cylinder 12. At this time, the adjustment of the brush roller 11 is completed.

[0027] (3) The operation button extends the tilting cylinder 3 and lifts the tilting frame 2, so that the working roll device reaches the horizontal (hoisting) position; after the upper working roll device and the lower working roll device are adjusted, they are assembled and put into the rolling mill for production, and the cleaning effect is observed.

[0028] The following is an example of finish rolling. The finish rolling process is largely the same as the rough rolling process, with the following differences: The inner surface of the placement slot of the flipping frame 2 is provided with a positioning pin 16 to avoid the wheels of the lower work roll of the finishing mill.

[0029] In a preferred embodiment, a pressing cylinder bracket 14 is provided on the side surface of the fixing frame 1, and a brush roller bearing seat pressing cylinder 15 is installed on the upper surface of the pressing cylinder bracket 14. In the finishing mill, the brush roller pressing device (such as the pressing cylinder 12) is not directly installed on the work roll assembly, and external force is required to press the brush roller bearing seat. Therefore, an external brush roller bearing seat pressing cylinder 15 is provided to apply pressure to the brush roller so that it can press the work roll.

[0030] The clamping cylinder 12, brush roller bearing seat pressing cylinder 15, tilting cylinder 3, operating side and transmission side clamping cylinder, pulsating cylinder, hydraulic motor and other components used in this application are all commonly used electronic components in the prior art. Their specific structure, working principle, control method and circuit connection are all known technologies and will not be described in detail here.

[0031] This invention simulates the actual working state of the working roller brush roller online. When the tilting cylinder extends, the tilting frame is horizontal, allowing the working roller assembly to be hoisted. After hoisting, the tilting cylinder retracts, and the working roller assembly tilts 20° on the tilting frame. Under the action of gravity, the working roller is completely pressed against the bearing seat, eliminating bearing clearance and simulating real working conditions.

[0032] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
