2600中板矫正机压下系统毕业设计说明书()

辽宁科技大学本科生毕业设计第I页2600中板矫正机压下系统设计摘要轧钢生产已经成为冶金生产行业中把钢坯轧制成钢材的重要生产环节，具有产量大、品种齐全，生产过程机械化自动化程度高等许多优点，是满足国民生产需要的重要技术。并且随着科学的发展，轧钢生产行业与传统机械业进一步紧密地结合在一起。利用轧钢生产技术，提高轧制产品的质量，减少轧制生产时间，提高成材率，降低生产成本和材料的利用率已经成为轧钢机械设计的主要目标。而矫正技术是提高板带钢产品表面质量和平坦度的重要环节。本文介绍了中厚板产生不平直度的原因及中厚板矫正机的类型。从2600中板矫直机的总体方案评述开始，先确定2600中厚板矫正机基本参数、力能参数，进一步依据板带矫正机的生产过程和工作原理，依次进行了压下电机的选择计算,压下螺丝、压下螺母、蜗轮蜗杆的设计及校核和轴承的设计及寿命校核。关键词：压下系统;矫正力;矫正机;辽宁科技大学本科生毕业设计第II页TheDesignOf2600TypePlateStraighteningMachinePressureSystemAbstractTheproductofsteelinghasbecomeanimportanttacheofrollingbillettobesteelsinthemetallurgyproduceindustry.Thestrongpointofthisindustryishavegreatoutputoftheproductionisthevarietyproduction.andtheproduceprocessisverymechanizationandautomatization.Thesteelingisaimportanttechnologytofulfillthecountryneed.Alsowiththedevelopmentofsteelingindustrytheindustryintegrateverywellwiththetraditionalmechanismindustry.Howtomakeuseofthesteelingmanufacturetechnology,enhancetherollingqualityoftheproduction,decreasetheproductofrollingtime,enhancetherateofproductusefulrolledsteel.Thestraightingtechnologyisaimportanttachetoenhancethesurfacequalityandflatnessoftheproduction.Thisarticledescribesthereasonsinflatednessoccurredonmediumandheavyplate．Thetypeoflevelers，thedeterminationofbasicparameters，energeticdatefor2600plateleveler,thedecisionforcompletestructureanddesign，thedevelopmentofplatelevelingtechnology.Thisarticledesignbasisontheboard-stripstraightingmachineproduceprocessandtheworkingprincipleinthesteelmetallurgy.Thisarticlefirstbeginwiththeschemereviewoftheenergeticdatefor2600.Thengoalongwithchoiceofthepressureelectromotor,thedesignandcheckingofpressingthenutandthepressurescrew,Wormandwormgearequipment.thandesignandcheckingthelifeofthebearing.Followingdesignedthelocalassessorandtheoverallstructure.Besidesresearchedthedevelopmentdirectionofthestraightingmachine.Keywords:Pressuresystem;Correctionforce;flatness辽宁科技大学本科生毕业设计第III页目录1.绪论....................................................................................................................11.1矫直机的发展状况.....................................................................................................11.2主要产品、技术性能及工艺参数.............................................................................11.2.1轧钢生产及产品种类.......................................................................................11.2.2技术性能及工艺..............................................................................................21.3矫正机的分类、用途及特点....................................................................................31.4辊式矫直机的工作原理、特点及结构组成：.........................................................32.总体方案..........................................................................................................42.1矫正方案及矫正工艺.................................................................................................42.2矫正机系统的组成及作用.........................................................................................52.2.1机座形式.........................................................................................................52.2.2主传动机构组成和作用..............................................................................52.2.3压下机构组成和作用....................................................................................72.2.4矫正辊的结构特点及轴承形式....................................................................83.矫正机结构参数和力能参数的确定................................................................93.1矫正机结构参数的确定............................................................................................103.2作用在螺丝上的最大矫正力的确定........................................................................114压下电机选择及校核...................................................................................134.1压下螺丝的设计.......................................................................................................134.2电机的选择................................................................................................................134.3电机过载校核............................................................................................................155.零件的设计及校核......................................................................................185.1压下螺母的强度设计及校核....................................................................................185.1.1螺母的高度的设计及校核............................................................................185.1.2压下螺母的外径的设计及校核.....................................................................195.2蜗轮蜗杆的设计及校核............................................................................................205.2.1蜗轮蜗杆的设计计算.....................................................................................205.2.2蜗杆的校核.....................................................................................................235.3蜗杆轴的强度校核及圆锥滚子轴承寿命计算.......................................................255.3.1蜗杆轴的强度校核........................................................................................255.3.2圆锥滚子轴承寿命计算..........................
