The hydraulic system is connected with the main oil cavity 12 through a high-pressure oil way, and is connected with the auxiliary oil cavity 11 through a low-pressure oil way; the pressure of the main oil chamber 12 is greater than that of the auxiliary oil chamber 11; the pressure of the main oil chamber 12 provides the rolling force.
The upper end of the pull rod 16 is provided with a pull rod driving mechanism 18.
The bearing assembly 20 may be formed by a combination of needle bearings and thrust bearings.
The working process is as follows: 1. the pull rod 16 is controlled to rotate by a pull rod driving mechanism 18, and the pull rod 16 is axially fixed and only can rotate under the limitation of a bearing assembly 20 and an axial fixing platform 19.
2.

3. When the device works, the preset roll gap is A. Firstly, the roll gap is adjusted to be A + (1-50 mm) by a mechanical adjustment mode (the pull rod 16 rotates), and the pull rod 16 keeps axially static. The main oil cavity 12 is filled with oil, so that the upper roller box 9 and the lower roller box 21 move oppositely, and after the preset roller gap distance A is reached through the position information transmitted by the upper displacement sensor 7 and the lower displacement sensor 5, the upper roller box 9 and the lower roller box 21 are kept static. Then the oil is fed into the auxiliary oil chamber 11, the upper roller box 9 and the lower roller box 21 move backwards, after the auxiliary oil chamber 11 reaches the preset pressure, the pull rod 16 reaches the specified prestress state, and simultaneously, the upper main nut 13, the lower main nut 1 and the pull rod 16 are in a locking state due to the fact that the pressure acting on the upper main nut 13 and the lower main nut 1 is large. During rolling, the pressure of the auxiliary oil chamber 11 is kept constant all the time, and the upper main nut 13 and the lower main nut 21 are kept in a locked state with the pull rod 16. If the roll gap distance is increased, the high-pressure oil cavity is fed with oil again, and the required roll gap value is finally achieved through the action of the automatic central processing unit. And finishing the roll gap adjustment before the rolling mill works.
When the rolling mill works, if a roll gap (or the size of rolled steel) changes, the upper displacement sensor 7 and the lower displacement sensor 5 convert the sensed position change situation into an electric signal and transmit the electric signal to the central processing unit, the central processing unit compares the electric signal with a preset value and sends an instruction to the hydraulic system to command the main oil cavity 12 and the auxiliary oil cavity 11 to respectively feed oil or drain oil, so that the distance A of the roll gap is kept unchanged from the preset value, and the automatic control of the roll gap is realized.
