摘  要
薄板精制冷軋機(jī)是以四輥軋機(jī)為基礎(chǔ)，從運(yùn)動(dòng)參數(shù)、力能參數(shù)和幾何參數(shù)入手，經(jīng)改良設(shè)計(jì)的五輥軋機(jī)，兼?zhèn)渌妮伜土佨垯C(jī)的優(yōu)點(diǎn)，并具有結(jié)構(gòu)簡(jiǎn)單，安裝、調(diào)試方便，軋制精度較高的特點(diǎn)。冷軋機(jī)是冷軋生產(chǎn)的主體設(shè)備，為了滿足冷軋帶鋼生產(chǎn)的品種、規(guī)格、質(zhì)量及不同生產(chǎn)規(guī)模的要求，冷軋帶鋼生產(chǎn)工藝經(jīng)歷了從單張到成卷生產(chǎn)的變革，由可逆式連軋到全連續(xù)聯(lián)合機(jī)組的發(fā)展，形成了各種形式和不同特色的冷軋機(jī)?，F(xiàn)代冷軋機(jī)的裝備水平也有了很大提高，并趨向高效率、高質(zhì)量、連續(xù)化和自動(dòng)化。冷軋機(jī)成為現(xiàn)代鋼鐵工業(yè)中高效率生產(chǎn)設(shè)備之一，是鋼鐵工業(yè)技術(shù)發(fā)展和裝備水平提高的一個(gè)重要標(biāo)志。本文綜述了薄板冷軋的發(fā)展和冷軋機(jī)的工作特點(diǎn)，按照機(jī)械設(shè)計(jì)的要求，采用相關(guān)理論與經(jīng)驗(yàn)公式對(duì)主要零件進(jìn)行了設(shè)計(jì)計(jì)算；包括總體方案設(shè)計(jì)，主傳動(dòng)系統(tǒng)設(shè)計(jì)，壓下系統(tǒng)設(shè)計(jì)，機(jī)架設(shè)計(jì)和三維模擬裝配等內(nèi)容；對(duì)方案的可行性，可靠性進(jìn)行了討論，最后得出結(jié)論：設(shè)計(jì)的薄板精制冷軋機(jī)可以用于工業(yè)生產(chǎn)。

The design of thin refined cold rolling mill
Abstract
Plate rolling mill is made based on four rolling machine, from movement parameters, force can parameters and geometric parameters of the improved design, the five roller mill, have both four roll and six roller mill advantages, and has simple structure, convenient installation, commissioning, rolling precision of characteristic. Cold rolling mill is the main equipment of the cold rolling mill production line, in order to satisfy the varieties, cold strip mill production specifications, quality and different requirements, the production scale of cold strip mill production process has experienced from leaflet to volumes production change, by reversible type and rolling to the continuous development of joint unit, formed various forms and different characteristics of cold rolling mill. Modern cold rolling mill equipment level has greatly improved, and incline to high efficiency, high quality, continuous and automation. Cold rolling mill is one efficient production equipment of steel industries in modem iron and an important sign of the steel industry technology development and equipment level improvement. This paper reviews the development of sheet cold rolling mill and characteristics of the work, according to the mechanical design requirements, adopting relevant theoretical and empirical formula of the design and calculation of main parts; Including the content of overall scheme design, main transmission system design, pressing system design, frame design and 3d simulation assembling; The feasibility of schemes, reliability are discussed, and finally reached the design of rolling mill can invest in the conclusion of the actual.

Keywords: Thin refined, cold rolling mill, transmission system, pressing system, frame, analog assembly
