Split-type lateral backup roll swing arm structure for eighteen-high mill

Abstract

The invention provides a split-type lateral backup roll-swing arm structure for an eighteen-high mill. The split-type lateral backup roll-swing arm structure comprises swing arm assemblies and lateral backup roll assemblies, wherein the swing arm assemblies and the lateral backup roll assemblies are fixedly connected with each other via clamping cylinders. Therefore, the assembling of lateral backup rolls is completely independent of the roll system assembling of a middle roll, that is, during replacement of the middle roll, the lateral backup rolls are not required to be replaced together, so that the roll replacing frequency is reduced; the assembling of swing arms is independent of that of the lateral backup rolls, and the swing arms and the lateral backup rolls are connected with each other via the clamping cylinders, so that during roll replacement, only a lateral backup roll assembling part is required to be replaced, that is, the efficiency and the speed for replacement of the lateral backup roll are improved; the roll system assembling of the middle roll is completely independent, so that a bearing block is not required to be designed into a floating structure, not only can the structure of the middle roll be simplified, but also the roll replacing operation can be more convenient and quicker; due to the design of C-shaped swing arm body structures, T-shaped clamping cylinder heads and positioning baffles, the lateral backup roll assemblies can be positioned precisely.

Description

technical field [0001] The invention relates to an 18-high rolling mill in the field of stainless steel cold rolling, in particular to a split-type side support roll swing arm structure of the 18-high rolling mill. Background technique [0002] Eighteen-high rolling mills are widely used in continuous cold rolling of stainless steel. Due to the small diameter of the work rolls and poor horizontal rigidity, side support rolls are required to support the work rolls in the horizontal direction. [0003] The conventional structural forms of the side support rolls and swing arms of the 18-high rolling mill in this field are: the complete set of side support rolls and the swing arm are a set of accessories, and the hinge point of the swing arm, that is, the rotation center of the swing arm, is fixed on the bearing housing of the middle roll. Side support rollers and swing arms are assembled together with the middle roller as a complete set. [0004] The main disadvantages of this...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem that the existing 18-high rolling mill's side support rolls, swing arms and middle rolls are set parts, resulting in a substantial increase in the operation and maintenance workload of the side support rolls and middle rolls, thereby affecting production efficiency and cost.
