【摘要】：在國(guó)民經(jīng)濟(jì)快速發(fā)展的今天,鎳這種多功能型的金屬材料被越來(lái)越多的行業(yè)所應(yīng)用。目前世界上生產(chǎn)鎳以電解精煉方法為主,電流經(jīng)電解槽流向?qū)щ姲?經(jīng)吊耳流向種板。但是導(dǎo)電棒在使用過(guò)程中常因?yàn)槭茌d、敲打等原因發(fā)生彎曲變形。使用彎曲變形的導(dǎo)電棒會(huì)影響電鎳的電解效率和制作始極片的自動(dòng)化程度,嚴(yán)重的會(huì)發(fā)生安全事故,所以導(dǎo)電棒再次使用前必須進(jìn)行矯直。國(guó)內(nèi)現(xiàn)在存在管棒材專用的矯直機(jī),但是因?yàn)槌C直精度低、矯直質(zhì)量不穩(wěn)定、存在矯直盲區(qū)等原因沒(méi)被大部分企業(yè)認(rèn)可接受。轉(zhuǎn)轂式斜輥矯直機(jī)是一種新型的矯直裝置,可以用于矯直導(dǎo)電棒,但是因?yàn)榻Y(jié)構(gòu)參數(shù)設(shè)置、工藝參數(shù)調(diào)節(jié)等原因使轉(zhuǎn)轂式斜輥矯直機(jī)不能很好滿足生產(chǎn)實(shí)際需要。本課題以轉(zhuǎn)轂式斜輥矯直機(jī)為研究對(duì)象,利用單旋轉(zhuǎn)轂式矯直機(jī)隨機(jī)對(duì)50根電鎳導(dǎo)電棒進(jìn)行實(shí)驗(yàn)并測(cè)量其矯直前后的平直度,從而發(fā)現(xiàn)該種矯直機(jī)的弊端并在此基礎(chǔ)上進(jìn)行設(shè)計(jì)和改進(jìn)。根據(jù)金屬?gòu)椝苄詮澢碚?分析了強(qiáng)化金屬材料管材在彎曲時(shí)的塑性區(qū)變形分布規(guī)律,并建立了管材彎曲時(shí)的曲率比方程和彎矩比大小;推導(dǎo)出管材彎曲時(shí)的能量比和精度范圍。在單旋轉(zhuǎn)轂式矯直機(jī)的工作原理基礎(chǔ)上,得到雙旋轉(zhuǎn)轂矯直機(jī)的簡(jiǎn)化力學(xué)模型和壓彎撓度,分析了其矯直優(yōu)點(diǎn),設(shè)計(jì)了輥?zhàn)优挪挤绞?計(jì)算了輥距、輥形等機(jī)構(gòu)參數(shù)和矯直速度、輥?zhàn)有苯堑裙に噮?shù)。應(yīng)用有限元分析軟件Deform 3D進(jìn)行模擬仿真,對(duì)導(dǎo)電棒從咬入到穩(wěn)定矯直再到順利拋出的矯直過(guò)程進(jìn)行動(dòng)態(tài)觀察,對(duì)矯直過(guò)程中導(dǎo)電棒的等效應(yīng)力分布和矯后導(dǎo)電棒平直度進(jìn)行了著重分析研究。采用單一變量法分別研究了轉(zhuǎn)轂的旋向、拉料速度差以及螺旋導(dǎo)程對(duì)矯直效果的影響。本文將實(shí)驗(yàn)分析和有限元模擬結(jié)合起來(lái)對(duì)導(dǎo)電棒的矯直過(guò)程進(jìn)行研究,結(jié)合單旋轉(zhuǎn)轂式矯直機(jī)的不足,設(shè)計(jì)出雙旋轉(zhuǎn)轂式矯直機(jī),并研究特定的矯直參數(shù)對(duì)矯直效果的影響,為雙旋轉(zhuǎn)轂式矯直機(jī)的設(shè)計(jì)和實(shí)際矯直提供了理論依據(jù),具有一定的實(shí)用價(jià)值和指導(dǎo)意義。
[Abstract]:With the rapid development of the national economy, nickel, a multifunctional metal material, has been used in more and more industries. At present, nickel is produced mainly by electrolytic refining, and the current flows to the conducting rod through the electrolytic cell. However, during the use of conductive rods, bending deformation often occurs due to load, beating and other reasons. The use of bending deformed conductive rods will affect the electrolysis efficiency of nickel electrolysis and the automation degree of the initial electrode. Serious safety accidents will occur, so the conductive rod must be straightened before re-use. There is a special straightener for tube bar in China now, but because of the low straightening accuracy, the straightening quality is unstable. The reason of straightening blind area is not accepted by most enterprises. The hub inclined roll straightener is a new type of straightening device, which can be used to straighten the conductive rod, but because of the structure parameter setting. The adjustment of process parameters makes the hub tilting roller straightening machine can not meet the actual production needs well. This topic takes the hub type inclined roll straightening machine as the research object. A single rotating hub straightener was used to test 50 electric nickel conducting rods at random and the straightness before and after straightening was measured. Based on the theory of metal elastic-plastic bending, the deformation distribution law of plastic zone of reinforced metal pipe in bending is analyzed. The curvature ratio equation and bending moment ratio are established. Based on the working principle of single rotating hub straightener, the simplified mechanical model and bending deflection of double rotating hub straightener are obtained, and the advantages of straightening are analyzed. The arrangement of roller is designed, and the parameters of roller spacing, roll shape, straightening speed and roll angle are calculated. The finite element analysis software Deform 3D is used to simulate and simulate. The dynamic observation was carried out on the straightening process of conducting rod from biting in to stabilizing straightening and then to throwing out smoothly. The equivalent stress distribution of conducting rod and the straightness of conducting rod after straightening are studied emphatically. The rotation direction of the hub is studied by single variable method. In this paper, the experimental analysis and finite element simulation are combined to study the straightening process of the conductive rod, combined with the shortcomings of the single rotating hub straightener. The double rotating hub straightener is designed, and the influence of certain straightening parameters on the straightening effect is studied, which provides a theoretical basis for the design and practice of the double rotating hub straightener. It has certain practical value and guiding significance.
