鑄造工藝畢業(yè)設(shè)計(jì)【篇一：鑄造工藝畢業(yè)論文】畢業(yè)論文題目淺談鑄造工藝與品質(zhì)檢查姓名所在系別專業(yè)班級(jí)學(xué)號(hào)指導(dǎo)教師日期摘要：為了提高鑄件的可靠性、適用性；提高產(chǎn)品在市場(chǎng)上的競(jìng)爭(zhēng)能力，對(duì)鑄件質(zhì)量的要求不斷提高。鑄件質(zhì)量的概念也發(fā)生了相應(yīng)的變化，“質(zhì)量”的含義至少包含兩個(gè)方面的內(nèi)容：一是產(chǎn)品質(zhì)量，即鑄件滿足用戶要求的程度；或按其用途在使用中應(yīng)取得的功效，這功效是反映鑄件結(jié)構(gòu)特征、材質(zhì)的工作特性和物理力學(xué)特性的總和，是評(píng)價(jià)鑄件質(zhì)量水平和技術(shù)水平的基本指標(biāo)。二是工程質(zhì)量，指的是鑄制毛坯和鑄制零件的生產(chǎn)過(guò)程對(duì)產(chǎn)品質(zhì)量的保證程度，即鑄件在具體使用條件下的可靠性。這一指標(biāo)在相當(dāng)大的程度上決定于前述的功效指標(biāo)，還與穩(wěn)定性、耐用性和工藝性等指標(biāo)有關(guān)。標(biāo)準(zhǔn)是由國(guó)家承認(rèn)的標(biāo)準(zhǔn)制訂單位批準(zhǔn)的對(duì)各種產(chǎn)品（鑄件）規(guī)格、材料規(guī)格、試驗(yàn)方法、術(shù)語(yǔ)定義或推薦的工藝方法的規(guī)定。我國(guó)的國(guó)家標(biāo)準(zhǔn)是由國(guó)家技術(shù)監(jiān)督局批準(zhǔn)并頒行的，有關(guān)鑄件質(zhì)量的各種標(biāo)準(zhǔn)一經(jīng)接納、貫徹與實(shí)施，可取得明顯的效果和效益。國(guó)際標(biāo)準(zhǔn)是由國(guó)際標(biāo)準(zhǔn)化組織批準(zhǔn)并頒行的。我國(guó)是國(guó)際標(biāo)準(zhǔn)化組織的主要成員國(guó)之一，按國(guó)家現(xiàn)行的政策,國(guó)際標(biāo)準(zhǔn)可以等效地視為國(guó)家標(biāo)準(zhǔn)。關(guān)鍵詞：鑄件質(zhì)量；提高鑄件品質(zhì)；穩(wěn)定性；耐用性目錄引言...........................................................................3第一章鑄件質(zhì)量標(biāo)準(zhǔn).............................................................41.1鑄件精度標(biāo)準(zhǔn)............................................................4第二章鑄件缺陷分類.............................................................62.1鑄件缺陷................................................................62.2廢品與鑄件質(zhì)量.........................................................112.3修補(bǔ)與缺陷防止.........................................................11第三章鑄造過(guò)程中的質(zhì)量控制技術(shù).................................錯(cuò)誤！未定義書簽。3.1影響鑄件質(zhì)量的因素.....................................................123.2技術(shù)準(zhǔn)備過(guò)程的質(zhì)量控制.................................................133.2.1質(zhì)量標(biāo)準(zhǔn)的制定.......................................................133.2.2鑄件設(shè)計(jì).........................................................143.2.3鑄造工藝、工裝設(shè)計(jì)及驗(yàn)證.........................................153.3生產(chǎn)工藝過(guò)程的質(zhì)量控制.................................................153.3.1原材料的質(zhì)量控制.................................................153.3.2設(shè)備及工裝的質(zhì)量控制.............................................163.3.3工藝過(guò)程的質(zhì)量控制..............................................16第四章鑄件質(zhì)量檢測(cè)技術(shù)與缺陷診斷方法...........................................174.1鑄件外觀質(zhì)量檢測(cè)........................................................174.1.1鑄件形狀和尺寸檢測(cè)..............................................174.2鑄件內(nèi)在質(zhì)量檢測(cè).......................................................174.3鑄件質(zhì)量無(wú)損檢測(cè)技術(shù)...................................................18結(jié)論.........................................................................18參考文獻(xiàn)???????????????????????????????..19答謝。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。20引言鑄造產(chǎn)品品質(zhì)內(nèi)在質(zhì)量主要有：化學(xué)成分、金相組織、冶金缺陷、物理力學(xué)性能、可靠程度、晶粒度(共晶團(tuán)數(shù))、共晶飽和度、致密度、純度、連續(xù)度等。這些內(nèi)在質(zhì)量會(huì)影響使用質(zhì)量主要有：切削性能、焊接性能、運(yùn)轉(zhuǎn)性能、耐磨性能、耐蝕性能、耐溫性能、工作壽命及其它工作條件要求等，而且其指標(biāo)也在不斷提高。1、爐前鐵液成份檢測(cè)直讀光譜分析儀：分析研究有害微量元素群-特別是氣體元素n、0、h。2、鑄造原材料質(zhì)量檢測(cè)“x熒光能譜儀”就能在5分鐘之內(nèi)完成作為球化劑、孕育劑的各種鐵合金、脫硫劑、爐渣、耐火材料、礦物等原材料的全分析。便攜鑄造工藝圖、鑄件圖和模樣圖。本題目的研究方法，是運(yùn)用所學(xué)《材料成形工藝基礎(chǔ)》中的鑄造成形理論，對(duì)金屬液在充型、結(jié)晶、凝固和冷卻過(guò)程中發(fā)生的一系列物理、化學(xué)的變化及鑄件內(nèi)部的變化進(jìn)行了理論研究和分析。對(duì)如何保證鑄件的質(zhì)量，在合金液的成分上進(jìn)行了研究和探討，對(duì)工藝上采取的相應(yīng)措施進(jìn)行了可行性的研究和探討，針對(duì)本題目，如何運(yùn)用灰鑄鐵(ht250)鑄造出所要求的零件的鑄造成型工藝作了詳細(xì)闡述，對(duì)運(yùn)用砂型鑄造設(shè)計(jì)的澆注系統(tǒng)做出了詳細(xì)設(shè)計(jì)，并做出了鑄型裝配圖，鑄造工藝圖和模樣圖。關(guān)鍵詞：砂型鑄造澆注系統(tǒng)鑄造工藝圖模樣鑄型裝配圖ht250abstractthedesignprojectistocompletethetaskofformingprocessforkpartsoflathedialtheformingdesign,accordingtothenatureoftheproductionofadesign,partstructuralcharacteristicsandusestodeterminethemethodusedtomakethecastingformingprocessoftheroughparts.thespecificcontentsofthecastingprocessinthedesign,castingprocessparametersidentified,thesandcoredesign,gatingsystemdesign,riserdesign,thedesignofcoldiron,andoutofholes,sandandsandcoreofdrying,butalsoonthecastingassemblyhasbeendesigned,includingappearance,templates,coreboxesandsandboxesandotherdesigns.assemblydiagramdrawnoutprocess,castingprocessmaps,chartsandpatterncastingmap.thesubjectofresearchmethodsistousewhattheyhavelearnedmaterialformingtechnologybaseinthecastingformingthetheoryofliquidinthefillingofmetal,crystal,solidificationandcoolingprocessinaseriesofphysicalandchemicalchangesandchangesinthecastingsthetheoreticalresearchandanalysis.castingonhowtoensurethequalityoftheingredientsintheliquidalloywascarriedoutresearchandstudyontheprocesstotaketheappropriatemeasurestostudyandexplorethefeasibility.accordingtothistopic,howtoapplygrey(ht250)castingoutthepartsrequiredthecastingmoldingprocesswerediscussedindetail,tousethesandcastinggatingsystemdesign,andhasmadethedetaileddesigndrawingsmadecasting,castingprocesschar

鑄造和特種鑄造兩大類。砂型鑄造適用于金屬材料、大小、形狀和批量不同的各種鑄件，成本低廉，由砂型鑄造生產(chǎn)的鑄件占鑄件總產(chǎn)量的90%以上，特種鑄造是指砂型鑄造以外的鑄造工藝，常見的有熔模鑄造、金屬型鑄造、壓力鑄造、低壓鑄造和離心鑄造等。鑄造具有很多特點(diǎn)，與其他形成工藝相比，它不受零件毛坯的重量，尺寸和形狀的限制，重量從幾克到幾百噸，壁厚由0.3mm到1m，形狀十分復(fù)雜，用機(jī)械加工比較困難，耗費(fèi)大量機(jī)床工時(shí)，甚至難以制得得零件，都可以用鑄造方法獲得。鑄造由于可選用多種多樣成分，加之基本建設(shè)投資小，工藝靈活性大和生產(chǎn)周期短等優(yōu)點(diǎn)因而廣泛地應(yīng)用在機(jī)械制造，礦山冶金交通運(yùn)輸，石化通用設(shè)備，農(nóng)業(yè)機(jī)械，能源電力，輕工紡織，家用電器，土建工程，電力電子，航天航空，國(guó)防軍工等國(guó)民經(jīng)濟(jì)各部門，是現(xiàn)代大工業(yè)機(jī)械的基礎(chǔ)。鑄造工藝是鑄造生產(chǎn)的核心，是能否生產(chǎn)優(yōu)質(zhì)鑄件的關(guān)鍵，這也是本論文的關(guān)鍵內(nèi)容。古今中外都把提高和發(fā)展工藝水平，視為推動(dòng)行業(yè)技術(shù)進(jìn)步，滿足經(jīng)濟(jì)和社會(huì)發(fā)展需要的一個(gè)重要組成部分。【篇三：鑄造工藝畢業(yè)論文】摘要首先，分析零件的技術(shù)條件，明確零件的材料組成以及性能要求。對(duì)零件結(jié)構(gòu)的鑄造工藝性進(jìn)行分析，明確零件的結(jié)構(gòu)特點(diǎn)，找出可能存在的結(jié)構(gòu)問(wèn)題。提出改進(jìn)措施或預(yù)防缺陷的措施。其次,根據(jù)零件結(jié)構(gòu)特點(diǎn)，技術(shù)要求，生產(chǎn)要求，生產(chǎn)批量，生產(chǎn)條件選擇鑄造及造型方法。由零件的結(jié)構(gòu)特點(diǎn)，提出多種澆注和分型方案，綜合對(duì)比分析，選擇最為理想的澆注位置及分型面。制定出詳細(xì)的鑄造工藝方案。再次,根據(jù)鑄造工藝方案和零件的特點(diǎn)，選用適宜的工藝參數(shù)，設(shè)計(jì)鑄件的補(bǔ)縮系統(tǒng)，澆注系統(tǒng)。繪制出鑄造工藝圖。最后,設(shè)計(jì)鑄造工藝裝備，包括模板和芯盒,繪制模板和芯盒的裝配圖。關(guān)鍵字：鑄造工藝性；鑄造工藝方案；鑄造工藝參數(shù)；補(bǔ)縮系統(tǒng)；澆注系統(tǒng)abstractfirstofall,ianalysethetechnicalconditionsofthepartstoclearthematerialcompositionandperformancerequirementsofparts,analysethecastingprocessofthepartstructuretoclearthestructuralfeaturesofparts,identifypossiblestructuralproblemandproposemeasurestoimprovethestructureofpartsorthepreventionofdefective。secondly,accordingtostructuralcharacteristicsofparts,technicalrequirements,productionrequirements,productionvolume,productionconditionsichoosemethodsofcastingandmodeling.accordingtothestructuralcharacteristicsofcomponents,idevelopavarietyofpouringandpartingprogrammes,analysecomprehensivelyandcomparatively,choosethebestpouringpositionandpartingplananddevelopadetailedprogrammeofcastingprocess.again,accordingtotheprogrammeandstructuralcharacteristicsofparts,iselecttheappropriatetechnicalparameters,designfeedingsystemandpouringsystem.ofthecasting,mapoutthecastingprocessplans.finally,idesignthecastingprocessequipment,includingthetemplatesandcore-boxesanddrawtheassemblyplansoftemplateandcore-box.keyword:castingprocess；castingprocessprogramme；castingprocessparameters；feedingsystem；catingsystem摘要...............................................................................................................................iabstract.................................................................................................................ii緒論...............................................................................................................................11零件材料性能分析.................................................................................................22零件結(jié)構(gòu)的鑄造工藝性分析.................................................................................33鑄造工藝方案的確定.............................................................................................73.1分型的分析比較與選擇....................................................................................73.1.1方案一............................................................................................................73.1.2方案二............................................................................................................83.1.3方案三............................................................................................................93.2造型方案............................................................................................................93.3造型（芯）方法的選擇..................................................................................103.4鑄型種類的選擇..............................................................................................103.5澆注位置的確定..............................................................................................113.6砂箱中鑄件數(shù)目的確定..................................................................................113.7砂芯的設(shè)計(jì).......................................................................................................113.7.1砂芯尺寸......................................................................................................113.7.2下芯順序......................................................................................................124鑄造工藝參數(shù)的選擇...........................................................................................134.1鑄件線收縮率..................................................................................................134.2機(jī)械加工余量..................................................................................................134.3起模斜度的選取..............................................................................................145鑄件體積的計(jì)算...................................................................................................155.1實(shí)體部分體積..................................................................................................165.2去除部分體積..................
