河南机电高等专科学校毕业设计设计题目：轴承座铸造工艺设计系部材料工程系专业材料成型与控制技术班级材料111学生姓名刘欢学号111308103指导教师邓想xxxx年月日轴承座铸造工艺设计摘要：本轴承座为一小型铸件，铸件材质为ZG230-450，结构简单，无复杂的型腔和阻碍起模的凸起。铸件的外形尺寸为350mm×350mm×175mm，主要壁厚为30mm，壁厚基本均匀。轴承座采用ZG230-450是一种铸造碳钢，是新牌号表示方法(GB11352-89)，原牌号叫ZG25。从轴承座的整体结构特点出发，进行铸造工艺设计分析，确定铸造方案，并进行铸造工艺参数和砂芯的设计，在此基础上再根据铸件的材质重量和浇注系统性能设计补缩系统。采用水玻璃砂手工造型、制芯、木摸样和开放式浇注系统，设计时应综合考虑各方面因素，浇注系统不是简单地金属液流动通道，用solidworks三维造型后，采用华铸CAE软件对设计方案进行浇注、凝固模拟计算。结果显示，浇注系统设计合理，缩松缩孔缺陷留在了冒口区。关键词：轴承座，工艺设计，华铸CAEBEARINGCASTINGPROCESSDESIGNABSTRACT:Thebearingasasmall-sizedcastings,castingmaterialofZG230-450,simplestructure,nocomplexcavityandobstaclestodraw.Theappearanceofthecastingsizeis350mm×350mm×350mm,themainwallthicknessof30mm,basicuniformwallthickness.BearingtheZG230-450isakindofcastingsteel,isanewbrandrepresentation(GB11352-89),theoriginalbrandnameisZG25.Fromtheoverallstructureofthebearingcharacteristics,analysisofcastingprocessdesign,determinethecastingsolution,andcastingprocessparametersandthedesignofsandcore,onthisbasis,accordingtothematerialweightofthecastingandpouringsystemperformancedesignofthefeedingsystem.Usedsodiumsilicatesandhandmademoldingandcoremaking,woodtouchkindandopengatingsystem,thedesignshouldbeconsideredwhenthefactors,thegatingsystemisnotsimplythemetalliquidflowchannel,withsolidworks3dmodelling,theChinafoundryCAEsoftwareisadoptedtodesignplansforpouringandsolidificationsimulation.Resultsshowthatthepouringsystemdesignisreasonable,theshrinkageporositydefectontheKouOu.KEYWORDS:Bearingseat，Processdesign，ChinaCastingCAE目录1绪论........................................................................11.1国外铸造技术发展状况..................................................11.2我国铸造技术的现状....................................................21.3铸造工艺设计的基本知识................................................21.4铸造工艺设计的重要性..................................................22铸造方案的确定..............................................................32.1零件的材质分析........................................................32.2轴承座工艺设计的内容和要求............................................32.3轴承座结构的铸造工艺性分析............................................52.4造型造芯方法的选择....................................................52.5浇注位置的选择........................................................62.6轴承座分型面的选择....................................................72.7砂箱中铸件数目的确定..................................................83铸造工艺参数的确定.........................................................93.1铸件最小铸出壁厚......................................................93.2最小铸出的孔和槽......................................................93.3铸件的尺寸公差........................................................93.4机械加工余量.........................................................103.5铸造收缩率...........................................................103.6起模斜度.....................
