本科畢業(yè)設(shè)計(jì)(論文)題目：高溫合金零件電解加工工裝設(shè)計(jì)系別：機(jī)電信息系專業(yè)：機(jī)械設(shè)計(jì)制造及其自動(dòng)化班級(jí)：學(xué)生：學(xué)號(hào)：指導(dǎo)教師：2013年05月I高溫合金零件電解加工工裝設(shè)計(jì)摘要電解加工又稱電化學(xué)加工，是金屬工件在電解液中發(fā)生陽(yáng)極溶解的一種加工過(guò)程。電解加工對(duì)難加工材料可以以柔克剛，對(duì)形狀復(fù)雜的零件可以一次成型，并以表面質(zhì)量好、生產(chǎn)率高、無(wú)工具損耗、無(wú)切削應(yīng)力等優(yōu)點(diǎn)，在制造業(yè)中發(fā)揮著重要作用。論文通過(guò)對(duì)高溫合金零件進(jìn)行分析，設(shè)計(jì)出一套電解加工工裝。電解加工工裝包括陰極的設(shè)計(jì)計(jì)算、流場(chǎng)的設(shè)計(jì)計(jì)算以及零件的定位等。陰極的設(shè)計(jì)采用等間隙分布的原則，在零件原有尺寸上縮小一定的間隙，來(lái)設(shè)計(jì)陰極。根據(jù)不同的加工方式可以有不同的加工間隙，這里取加工間隙為0.5mm。對(duì)于流場(chǎng)的設(shè)計(jì)，根據(jù)零件的特點(diǎn)采用側(cè)流式加工，在流場(chǎng)設(shè)計(jì)時(shí)還要確定電解液流速和進(jìn)口壓力。另外，流場(chǎng)的設(shè)計(jì)要均勻，均勻性是指加工面上各處流量充足、均勻，不發(fā)生流線相交和其他流場(chǎng)缺陷如空穴現(xiàn)象、分離現(xiàn)象等。另外，工裝的設(shè)計(jì)要保證良好的密封性。通過(guò)設(shè)計(jì)電解加工工裝加工高溫合金零件比機(jī)械切削加工省時(shí)省力，與機(jī)械切削加工相比電解加工的表面質(zhì)量好，且加工范圍廣，沒(méi)有切削應(yīng)力。關(guān)鍵詞：電解加工；陰極設(shè)計(jì)；流場(chǎng)；工裝IIHightemperaturealloypartselectrochemicalmachiningtoolingdesignAbstractElectrochemicalmachiningisalsocalledelectrochemicalmachining,metalwor-kpieceintheelectrolyteisananodicdissolutionprocess.Electrochemicalmachiningofdifficult-to-machinematerialscan,withpartsofcomplexshapecanbeaforming,andwithgoodsurfacequality,highproductivity,toolwear,cuttingstress,playsanimportantroleinmanufacturing.Paperthroughtheanalysisofhightemperaturealloyparts,designasetofelectrochemicalmachiningtools.Electrochemicalmachiningfixturesincludingthedesignofthecathodeflowfieldcalculation,designcalculationandthepositioningparts.Cathodedesignbasedontheprincipleofdistributionofintermittent,reducedacertaingaponthepartsintheoriginalsize,todesignthecat-hode.Accordingtothedifferentprocessingmethodscanhavedifferentprocess-singclearance,heretakemachininggapis0.5mm.Tothedesignoftheflowfield,accor-dingtothecharacteristicsofthepartswithsideflowprocessing,evenwhenintheflowfielddesigntodeterminetheelectrolyteflowrateandinletpressure.Inaddition,thedesignoftheflowfieldtouniformandadequateflowthroughoutuniformityreferstoprocessingsurface,uniform,notlineintersectandotherdefects,suchascavitationflowfieldandseparationphenomenon,etc.Inaddition,thetoolingdesigntoensuregoodsealing.Throughelectrochemicalmachiningtoolingdesignthanmechanicalmachiningtime,hightemperaturealloypartscomparedwithmechanicalmachiningelectrolyticmachiningsurfacequalityisgood,andtheprocessingrangeiswide,nocuttingstress.KeyWords:Electrochemicalmachining；Thecathodedesign；Theflowfield；toolingIII目錄1緒論.11.1電解加工的原理.11.2電解加工的特點(diǎn)及分類.31.3電解加工的應(yīng)用及研究現(xiàn)狀.51.4本課題主要研究的目的、意義以及重點(diǎn)和難點(diǎn).61.5電解加工的研究方法以及電解加工新技術(shù).81.6電解加工的設(shè)備以及工藝發(fā)展.82高溫合金零件電解加工陰極的設(shè)計(jì)與計(jì)算.102.1電解加工成型規(guī)律的研究.102.2電解加工陰極設(shè)計(jì)的方法.102.3高溫合金零件陰極的設(shè)計(jì)與計(jì)算.122.4陰極設(shè)計(jì)的二維圖與三維圖.153高溫合金零件電解加工的流場(chǎng)設(shè)計(jì).173.1電解液的流動(dòng)形式.173.2電解液流速和進(jìn)口壓力的確定.183.2.1電解液流速的確定.183.2.2電解液壓力的確定.203.3流場(chǎng)均勻性的設(shè)計(jì).214高溫合金零件電解加工工裝的設(shè)計(jì)以及總體工裝夾具.234.1電解加工工裝的功能及特殊要求.234.2高溫合金零件陰極的定位與連接.244.3高溫合金零件電解加工底座的設(shè)計(jì).244.4陰極連接桿的設(shè)計(jì).254.
