Problems solved by technology

[0002] In the prior art, for the inner bearing of an intermediate roll chock of a cold-rolled single stand, when the maintenance cycle is reached (generally 150 hours online), it needs to be manually removed and then manually cleaned and maintained, otherwise it will continue to be used on the machine, and the It will have a great impact on the stable production of the rolling mill, and if it is not handled properly, it will cause bearing jamming and other conditions, which will further cause downtime accidents
[0003] Moreover, although the manual cleaning process has been relatively mature, there are still some shortcomings on the whole: 1. The bearing seat disassembly takes a long time; 2. The cleaning efficiency of the bearing seat is low; 3. The qualified rate after cleaning is not high; 4. The cleaning materials (Chemical cleaning agent) consumes a lot and pollutes
[0004] On the other hand, the conventional bearing seat cleaning device also has some disadvantages: 1. The bearing seat parts must be completely disassembled for each cleaning; 2. Each cleaning is mainly based on heating, soaking and shaking, which takes too long; 3. Cleaning materials ( Chemical cleaning agent) consumes a lot and pollutes
[0005] Because the cold-rolled intermediate roll bearing housing is mainly used in a 20-roll reversible single stand, it has been on the machine for a long time and is always in a state of high-speed rotation. In addition, the emulsion provided by the unit for lubrication is poor in cleanliness, so it leads to an intermediate roll bearing. The monthly consumption has remained high, which has brought great pressure on production costs and spare parts turnover
Moreover, an intermediate bearing sometimes causes the unit to stop due to failure, which directly affects the production of the unit.

Embodiment

[0081] Cold rolling 20-high single-stand reversible rolling mill, there are 4 middle rolls in the whole roll system. During the whole process of rolling plate shape control, through the movement of a middle roll, the 1 / 4 of the curling part of the plate will be waved. to the flattening effect. Each intermediate roller is equipped with a bearing seat on one side, and the internal structure of the bearing seat mainly includes thrust bearings, radial bearings, gap rings and other components.

[0082] The current cleaning and maintenance content of an intermediate roller bearing housing is as follows:

[0083] 1. When the maintenance cycle of the bearing in the bearing seat is up (150 hours online), it needs to be manually disassembled, disassembled, cleaned and maintained;

[0084] 2. For an intermediate bearing seat that got off the machine in an accident (such as stacked steel, broken strips and sticky steel, etc.), it needs to be manually disassembled, disassembled, cleaned a...

Abstract

The invention provides a cold rolling unit bearing pedestal disassembly-free cleaning device and cleaning method and application. The device comprises an ultrasonic generator and a closed flushing tank matched with the ultrasonic generator, a high-frequency pulse oscillation generator is arranged in the closed flushing tank, a bearing pedestal to be cleaned is placed in the closed flushing tank, an ultrasonic cleaning container is formed in an inner cavity of the bearing pedestal to be cleaned, a lubricating liquid inlet channel and a lubricating liquid outlet channel of a lubricating system of the bearing pedestal to be cleaned form a cleaning liquid inlet and a cleaning liquid outlet of the ultrasonic cleaning container correspondingly, the cleaning liquid inlet is connected with a cleaning liquid storage container through a multi-stage centrifugal pump, the cleaning liquid outlet is connected with the cleaning liquid storage container through a cleaning liquid return pipeline, and ashaft body of the bearing pedestal to be cleaned is connected with a centrifugal driving rotating shaft.

Description

technical field [0001] The invention relates to the technical field of equipment maintenance for cold rolling production, in particular to a no-cleaning device, cleaning method and application of a bearing seat of a cold rolling unit. Background technique [0002] In the prior art, for the inner bearing of an intermediate roll chock of a cold-rolled single stand, when the maintenance cycle is reached (generally 150 hours online), it needs to be manually removed and then manually cleaned and maintained, otherwise it will continue to be used on the machine, and the It will have a great impact on the stable production of the rolling mill, and if it is not handled properly, it will also cause bearing jams and other conditions, which will further cause downtime accidents. [0003] Moreover, although the manual cleaning process has been relatively mature, there are still some shortcomings on the whole: 1. The bearing seat disassembly takes a long time; 2. The cleaning efficiency o...
