Abstract

A single-side tower-type roller system based asynchronous rolling mill for rolling an ultra-thin composite strip and a hydraulic system therefor are provided. The mill includes a machine frame and reel assemblies. An upper roller system assembly and a lower roller system assembly are arranged in the machine frame. A down-pressing assembly is arranged on the machine frame and used to adjust a roll gap between the upper roller system assembly and the lower roller system assembly. A support roller balance assembly is arranged on the machine frame and used to support and balance the upper roller system assembly. The lower roller system assembly includes right and left working rollers. The right working roller is a plain roller. The left working roller is a patterned roller. A left-pressing assembly is arranged on the machine frame and used to adjust a roll gap between the right and left working rollers.

First claim

What is claimed is:

1. A single-sided tower-type roller system based asynchronous rolling mill for rolling an ultra-thin composite strip, comprising a machine frame which includes:
two groups of rectangular frames symmetrically arranged with respect to each other;
reel assemblies as an upper roller system assembly and a lower roller system assembly which are arranged at two opposite sides of the machine frame;
a down-pressing assembly arranged on the machine frame and configured to adjust a roll gap between the upper roller system assembly and the lower roller system assembly;
a support roller balance assembly arranged on the machine frame and configured to support and balance the upper roller system assembly; and
wherein the lower roller system assembly comprises a right working roller and a left working roller, the right working roller is a plain roller, the left working roller is a patterned roller, a left-pressing assembly is arranged on the machine frame and configured to adjust a roll gap between the right working roller and the left working roller, and the right working roller and the left working roller are driven by a motor drive assembly.

2. The single-sided tower-type roller system based asynchronous rolling mill according to claim 1 , wherein each of the reel assemblies comprises:
a reel; and
a tandem motor, configured to drive the reel to work;
wherein a side of the reel close to the machine frame is provided with a guide roller, and the guide roller is rotatably connected to a guide roller support.

3. The single-sided tower-type roller system based asynchronous rolling mill according to claim 2 , wherein the reel assemblies comprise:
two groups of unwinding reel assemblies, arranged at one of the two opposite sides of the machine frame; and
one group of winding reel assembly, arranged at the other of the two opposite sides of the machine frame;
wherein the two groups of unwinding reel assemblies are arranged vertical with respect to one another, and the guide roller corresponding to a lower one of the two groups of unwinding reel assemblies is arranged at the roll gap between the right working roller and the left working roller.

4. The single-sided tower-type roller system based asynchronous rolling mill according to claim 1 , wherein the upper roller system assembly comprises:
a six-roller system, arranged inside the two groups of rectangular frames; and
a six-roller rack, arranged outside the six-roller system;
wherein two opposite sides of the six-roller rack are individually provided with backing plates, and each of the backing plates is fixedly connected to the two groups of rectangular frames; and
wherein the six-roller system comprises an upper working roller, two first intermediate rollers arranged above and tangent to the upper working roller, and three second intermediate rollers arranged above the two first intermediate rollers, and axis centers of the upper working roller and the right working roller are located on a same vertical line.

5. The single-sided tower-type roller system based asynchronous rolling mill according to claim 4 , wherein each of two ends of the six-roller system is provided with a support end cover matched with the six-roller system, cylindrical protrusions are fixedly arranged on the support end cover and configured to keep six rollers to be axially fixed; and two of the cylindrical protrusions corresponding to the two first intermediate rollers are two axial displacement hydraulic cylinders.

6. The single-sided tower-type roller system based asynchronous rolling mill according to claim 4 , wherein the down-pressing assembly comprises a hydraulic cylinder, the hydraulic cylinder is fixedly connected to a corresponding one group of rectangular frame of the two groups of rectangular frames, a piston rod of the hydraulic cylinder goes through the corresponding one group of rectangular frame and is fixedly connected to a pressing head, the pressing head is connected to a pressure sensor, and the pressure sensor is connected to the six-roller rack.

7. The single-sided tower-type roller system based asynchronous rolling mill according to claim 4 , wherein the support roller balance assembly comprises a first balance beam fixedly connected onto the six-roller rack, and a second balance beam is fixedly connected between the two groups of rectangular frames;
wherein the first balance beam is fixedly connected to an end of a spring guide rod, another end of the spring guide rod goes through the second balance beam and is fixedly connected to a locking member, and the spring guide rod is sleeved with a balance spring between the locking member and the second balance beam.

8. The single-sided tower-type roller system based asynchronous rolling mill according to claim 1 , wherein each of two opposite ends of the right working roller is provided with a right working roller bearing seat, each of two opposite ends of the left working roller is provided with a left working roller bearing seat;
wherein the left-pressing assembly comprises:
the right working roller bearing seat and the left working roller bearing seat, arranged between two sides of a bottom portion of the same one of the two groups of rectangular frames; and
a small wedge and a large wedge, arranged at a side of the left working roller bearing seat facing away from the right working roller bearing seat;
wherein opposing surfaces of the small wedge and the large wedge are wedge-shaped surfaces, a groove is formed on a side of the same one group of rectangular frame close to the left working roller and configured to accommodate the small wedge, and the large wedge is fixedly connected to a wedge displacement hydraulic cylinder.
