Hydraulic working roll bending device for cold-rolling mill

Abstract

The invention relates to strip cold-rolling equipment, in particular to a hydraulic working roll bending device for a cold-rolling mill. The device comprises a stander and is characterized by also comprising embedded blocks, roll bending cylinders, a lower working roll system and an upper working roll system, wherein the roll bending cylinders are arranged in the embedded blocks; the embedded blocks are arranged on the stander by screws; and the lower working roll system and the upper working roll system are arranged between two embedded blocks. The device has the advantages of changing the radian of a working roll through the action of the roll bending cylinders without re-polishing the working roll, along with simple, compact and reasonable structure, spare part reduction, higher automation degree, low labor intensity, little auxiliary time, high work efficiency, simple structure and convenient manufacture.

Description

technical field [0001] The invention relates to a strip cold rolling equipment, in particular to a hydraulic bending device for working rolls of a cold rolling mill. Background technique [0002] At present, in the widely used four-high cold rolling mill, the work roll hydraulic bending device is not equipped, so that in the process of rolling the strip, the strip is usually rolled by manually grinding the radian of the work roll ;Because there are many specifications of the rolled strip, the arcs of the corresponding work rolls are not the same, resulting in the variety and specifications of the work rolls, which are difficult to manage, and the arcs of the work rolls are difficult to control, which affects the cold rolling mill. The quality of the rolled strip, the product quality is difficult to control, and the quality is unstable, which reduces the benefit of the enterprise. Contents of the invention [0003] The purpose of the present invention is to overcome the ab...
