New type 20 roller mill

Abstract

A novel 20-roller rolling mill is composed of integral rectangular machine frame, a roller box unit consisting of upper and lower roller boxes with rectangular saddle and lock unit, a dual-wedge regulator for said lower roller box and comprising swinging cylinder, swinging arm, connecting rod and wedge blocks, and the convexity controller consisting of hydraulic cylinder, rack bar and sectorial gear.

Description

technical field [0001] The invention relates to the field of rolling equipment, in particular to a novel 20-roll rolling mill. Background technique [0002] The 20-high mill is used to produce thin cold-rolled strip. The difficulty in the design of the 20-roll mill lies in the structure of the roll box. The cooperation between the roll box and the archway and the structure of the archway have a great influence on the performance of the rolling mill. Conventional roll boxes are very difficult to process, and the machining accuracy cannot be guaranteed, which affects the matching accuracy between the roll box and the arch window. It is also difficult for the conventional roll box to adapt to the actual situation that the roll system has a large roll diameter difference. Therefore, there should be a More rational design of rolling mill stand and roll box. [0003] In a traditional 20-roll rolling mill, the roll necks of the outer support rolls are supported on backing bearing...

AI Technical Summary

Problems solved by technology

The basic principle is that in the saddle between the backing bearings of support rollers B and C, an outer eccentric ring is installed outside the inner eccentric ring of the pressing device, and the eccentric ring is respectively driven by an adjusting hydraulic cylinder or a hydraulic motor The rotation of the eccentric ring, the rotation of any one of the ou
