[0020] The fully automatic hydraulic adjustment structure includes: a pair of equipment mounting slots 2, two pairs of mounting rails 3, bottom pressure rollers 4, adjustable clamping mounting components, top pressure rollers 5, a pair of first hydraulic cylinders 6, two pairs of second hydraulic cylinders 7, a pair of combined brackets 8, auxiliary fixing plates 9, and a pair of fixing pins 10.
[0021] A pair of equipment mounting slots 2 are formed on the mill stand 1, providing a base position for the installation of other components. Two pairs of mounting rails 3 are installed on the inner wall of the equipment mounting slots 2, providing guidance for the installation and movement of the bottom pressure roller 4 and the top pressure roller 5. The left end of the bottom pressure roller 4 is fixedly installed on the mounting rail 3. An adjustable clamping mounting assembly is installed on the right wall of the mill stand 1. The right end of the bottom pressure roller 4 is installed on the mounting rail 3 via the adjustable clamping mounting assembly. The top pressure roller 5 is movably installed on the mounting rail 3 and can move up and down on the mounting rail 3. Both the top pressure roller 5 and the bottom pressure roller 4 are installed in the equipment slots 2 via roller shaft supports, and the top pressure roller 5 and the bottom pressure roller 4 can rotate on the roller shaft supports. A pair of first liquid The pressure cylinder 6 is embedded on both sides of the top of the mill stand 1 and connected to the top pressure roller 5 through the connecting block 12, providing the main up and down movement power for the top pressure roller 5. Two pairs of second hydraulic cylinders 7 are embedded inside the pair of first hydraulic cylinders 6 and are installed on the mill stand 1 through the fixing bracket 13 and connected to the top pressure roller 5. The output ends of the two pairs of second hydraulic cylinders 7 are connected to the top pressure roller 5, which can finely adjust the position of the top pressure roller 5 and improve the adjustment accuracy. A pair of combined brackets 8 are installed on the right side wall of the mill stand 1, and the auxiliary fixing plate 9 is installed at the right end of the top pressure roller 5. The auxiliary fixing plate 9 is installed on the pair of combined brackets 8 through a pair of fixing pins 10, which plays the role of assisting in fixing the top pressure roller 5 and enhancing its stability.
[0022] In the specific implementation process, the bottom pressure roller 4 and the left end of the top pressure roller 5 are further provided with a rotating shaft connecting frame 11 for connecting with the external drive end.
[0023] In the specific implementation process, a pair of first hydraulic cylinders 6 are further mounted on the top pressure roller 5 via connecting block 12.
[0024] In the specific implementation process, the two pairs of second hydraulic cylinders 7 are further installed on the rolling mill frame 1 by fixed brackets 13 to ensure the stable installation of the second hydraulic cylinders 7.
[0025] In the specific implementation process, the adjustable clamping installation assembly further includes: a pair of equipment brackets 14, two pairs of rotating fastener brackets 15, a pair of threaded telescopic rods 16 and a pair of clamping grooves 17;
[0026] A pair of equipment brackets 14 are installed on the lower right side wall of the rolling mill frame 1. Two pairs of rotating fasteners 15 are movably installed on the pair of equipment brackets 14. A pair of threaded telescopic rods 16 are installed in the middle of the two pairs of rotating fasteners 15. A pair of clamping grooves 17 are opened on the bottom pressure roller 4.
[0027] In the specific implementation process, a pair of threaded telescopic rods 16 are further installed on two pairs of rotating fasteners 15 through hinge seats 18.

[0028] Working process: Before the rolling mill starts working, the bottom pressure roller 4 and the top pressure roller 5 are in their initial positions. The bottom pressure roller 4 is fixed in a suitable position by the adjustable clamping mounting assembly. The top pressure roller 5 is held at its initial height by the support of the first hydraulic cylinder 6 and the second hydraulic cylinder 7. The auxiliary fixing plate 9 is fixed to the combined support 8 by the fixing pin 10. According to the specifications of the rolled product, the control system controls the movement of the first hydraulic cylinder 6 and the second hydraulic cylinder 7. The first hydraulic cylinder 6 moves first, driving the top pressure roller 5 downward to its approximate position. Then, the second hydraulic cylinder 7 cooperates to make fine adjustments, so that the gap between the top pressure roller 5 and the bottom pressure roller 4 reaches the precise rolling position. To meet the required gap, the rolling mill drive device is activated, which drives the bottom pressure roller 4 and the top pressure roller 5 to rotate via the rotating shaft connecting frame 11, feeding the material to be rolled between the two rollers for rolling. During the rolling process, if it is necessary to adjust the rolling gap, the control system can control the action of the first hydraulic cylinder 6 and the second hydraulic cylinder 7 in real time based on the information fed back by the sensor, so as to realize the automatic adjustment of the rolling gap and ensure the stable quality of the rolled product. After the rolling work is completed, the first hydraulic cylinder 6 and the second hydraulic cylinder 7 are controlled to move the top pressure roller 5 upward to the initial position, the adjustable clamping installation component is released, and the bottom pressure roller 4 is returned to the initial position to prepare for the next rolling work.
