A strip steel finishing mill inlet guide device

Abstract

The invention discloses a strip steel finishing mill entry guiding device and belongs to the technical field of cold-rolling and calendaring. The strip steel finishing mill entry guiding device disclosed by the invention comprises a front guide device, a rear guide device and a bottom plate, wherein the rear guide device and the front guide device are sequentially arranged on the bottom plate along a strip steel movement direction; the rear guide device comprises a carrier roller and a pair of rear side guide mechanisms; the carrier roller is arranged along the strip steel width direction; thetwo rear side guide mechanisms are arranged on two sides of the bottom plate opposite to each other; the front guide device comprises a top-bottom guide mechanism and a pair of front side guide mechanisms; the top-bottom guide mechanism comprises a plurality of upper pressing belt rollers and lower pressing belt rollers arranged corresponding to one another from top to bottom; the upper pressingbelt rollers and lower pressing belt rollers are arranged along the strip steel width direction; and the two front side guide mechanisms are arranged on two sides of the bottom plate opposite to eachother. The strip steel finishing mill entry guiding device disclosed by the invention has main purposes that the whole rolling process of thick and thin materials after one-time guide completion is realized, so that the strip steel finishing mill entry guiding device disclosed by the invention can be applicable to strip steel guide with a wider thickness range.

Description

technical field [0001] The invention belongs to the technical field of cold rolling and rolling, and more specifically relates to an inlet guide device of a strip finish rolling mill with a thickness of 0.7-4.5mm. Background technique [0002] With the development of the national economy, the cold rolling and rolling industry is an indispensable part of industrial development. Since the development of the domestic rolling industry, a lot of improvements have been made in equipment manufacturing precision, roll systems, and automation. At the same time, many problems have been exposed in the production process, such as In the calendering industry, the product entering the roll before rolling must adopt guide position control. The purpose is to control the normal operation of the product on the center line of the equipment. At present, the domestic guide position control is divided into hydraulic guide position and mechanical guide position. Among them, the mechanical guide pos...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem that the guide device in the prior art cannot solve the problem that thick material and thin material can be rolled at one guide position, and the strip steel of the same specification does not have the automatic adjustment function of raw material width. , provides a strip steel finish rolling mill entrance guide device, adopts the technical scheme of the present invention, can make the strip steel run straight and smoothly along the transmission track of the rolling mill, ensure the smooth progress of rolling, and also realize the Thick material and thin material can complete the whole rolling process at one guide position, so that the inlet guide device of the strip steel finishing mill can be applied to the strip steel guide position with a wide range of thickness. In addition, by setting the wire pressing spring, the The inlet guide device of the strip finishing mill has the function of automatically adjusting the width of the raw material, so as to solve the problem of positive and negative differences in the strip steel of the same specification
