Description
Technical Field

Background
Oil-gas lubrication is a novel lubrication technology, has incomparable superiority compared with the traditional oil fluid lubrication technology, is particularly suitable for occasions with severe working conditions such as high temperature, heavy load, high speed, extremely low speed, cooling water and dirt invasion lubrication points, has extremely small oil consumption, has a lubricating oil utilization rate close to 100 percent, and is the main trend of the lubrication of the roller bearing of the cold rolling mill in the future. The oil-gas lubrication of the middle roller of the rolling mill is divided into a male quick joint part and a female quick joint part. Wherein the female head of the quick connector is arranged on a bearing seat of the roller shifting device, and the male head is arranged on a bearing seat of the middle roller. However, in use, the phenomenon that the bearing seats of the middle roll of the rolling mill are burnt due to the fact that the male quick connectors and the female quick connectors cannot be aligned after roll replacement and oil gas cannot be normally supplied to the bearing seats is often caused.
The following reasons for the abnormal combination of the male and female quick connectors are found through intensive research:
1. the center height of the female head in the roller bearing seat is changed due to abrasion of the copper backing plate of the sliding rail of the middle roller bearing seat, so that the male head cannot be smoothly inserted into the female head.
2. Due to frequent replacement of the middle rollers, the abrasion and processing of the roller head of each middle roller are inconsistent, and the locking position locked by the roller shifting coupling locking block at each time is deviated. The meshing amount of the oil gas to the oil gas male head and the oil gas female head is only 9 mm. Once the roller diameter of the middle roller is worn, the oil-air lubrication male and female heads cannot be communicated, so that the roller bearing seat cannot be subjected to oil-air induction to burn the roller easily.
3. Because the fit clearance between the male head and the female head is small, the fault-tolerant capability is poor, and the small position error in the horizontal direction and the vertical direction can cause the male head and the female head not to be well combined, so that the lubrication failure is caused.
In view of the above, there is a need for an improved oil-air lubrication quick coupling device of the prior roll shifting device, so as to achieve reliable oil-air lubrication of the roll shifting device.
