哈爾濱工業(yè)大學(xué)華德應(yīng)用技術(shù)學(xué)院畢業(yè)設(shè)計（論文）-I-摘要冷沖模是廣泛運用的模具之一，但在特殊條件下也可進(jìn)行加熱，即熱沖壓模具。沖壓模具具有成本低，產(chǎn)品質(zhì)量穩(wěn)定，能加工多種性能，狀態(tài)的零件的特點。但在應(yīng)用時也受到模具壽命和生產(chǎn)安全等方面的制約。本文主要是根據(jù)零件的生產(chǎn)技術(shù)要求，設(shè)計了落料拉深的復(fù)合模具，同時設(shè)計了浮動式切邊模具。在第一套模具的設(shè)計中，主要采用的是落料和反拉深的結(jié)合，此結(jié)構(gòu)相對較為簡單。由于鎂合金的塑性成型需要在一定的溫度條件下才能實現(xiàn)，所以溫度的控制是一個關(guān)鍵點，在此采用了嵌入式電阻絲進(jìn)行電加熱，且輔以溫控系統(tǒng)的控制，成型溫度為100-350℃。第二套模具主要采用浮動式切邊，在該設(shè)計中主要是對切邊的行程進(jìn)行控制。各個導(dǎo)板計算需精確。關(guān)鍵詞冷沖壓；落料；拉深；浮動式切邊哈爾濱工業(yè)大學(xué)華德應(yīng)用技術(shù)學(xué)院畢業(yè)設(shè)計（論文）-II-AbstractDiemoldiswidelyusedasone,butunderspecialconditionscanalsobeheated,orhot-stampingdies.Stampingdiewithalowcost,productqualityandstability,toprocessavarietyofperformancecharacteristicsofthestateoftheparts.Butinactualapplicationhasalsobeendielifeandproductionofsecurityconstraints.Thisarticleisbasedontheproductionofsparepartstechnicalrequirements,designdrawingofthecompoundblankingdie,whilethedesignofthefloatingtrimmingdie.Inthefirstsetofmolddesign,themainuseofthematerialandanti-pulloffacombinationofdeep,thisstructureisrelativelysimple.Theplasticmoldingofmagnesiumalloysduetotheneedatacertaintemperatureconditionscanbeachieved,sotemperaturecontrolisakeypoint,inthisuseoftheembeddedresistorwireforelectricheating,andsupplementedwiththecontroloftemperaturecontrolsystem,moldingtemperatureof100-350℃.Thesecondsetofmoldsusedmainlyfloatingtrimming,inwhichthedesignofthetripmainlyfortrimmingcontrol.Eachguideplatebeaccuratelycalculated.KeywordsWarmstamping；falltoexpect；pulldeeply；floatingbeadcut哈爾濱工業(yè)大學(xué)華德應(yīng)用技術(shù)學(xué)院畢業(yè)設(shè)計（論文）-III-目錄摘要.................................................................................................................IAbstract..........................................................................................................II第1章緒論...................................................................................................11.1模具行業(yè)發(fā)展的現(xiàn)狀及未來發(fā)展趨勢..............................................11.1.1模具行業(yè)發(fā)展現(xiàn)狀及技術(shù)趨勢現(xiàn)狀...........................................11.1.2我國及國外模具行業(yè)的發(fā)展?fàn)顩r及發(fā)展趨勢...........................31.1.3未來沖壓模具制造技術(shù)發(fā)展趨勢...............................................41.2課題研究的目的意義及主要內(nèi)容......................................................61.2.1課題研究的目的及意義...............................................................61.2.2本課題的主要研究內(nèi)容...............................................................6第2章零件的工藝性分析...........................................................................82.1零件的工藝性分析..............................................................................82.1.1沖裁件的精度與粗糙度...............................................................82.1.2沖裁件的材料...............................................................................82.2工藝方案的確定..................................................................................82.2.1工藝方案.......................................................................................82.2.2排樣的確定...................................................................................92.2.3沖裁件的排樣...............................................................................92.2.4搭邊...............................................................................................92.2.5材料利用率.................................................................................102.2.6模具及板材的溫度.....................................................................112.3本章小結(jié)............................................................................................11第3章沖壓模具總體結(jié)構(gòu)設(shè)計.................................................................123.1模具總體結(jié)構(gòu)設(shè)計............................................................................123.1.1模具形式.....................................................................................123.1.2操作與定位方式.........................................................................123.1.3送料卸料方式.............................................................................123.1.4模架類型及精度.........................................................................133.2本章小結(jié)............................................................................................13第4章沖壓模具工藝與設(shè)計計算.............................................................14哈爾濱工業(yè)大學(xué)華德應(yīng)用技術(shù)學(xué)院畢業(yè)設(shè)計（論文）-IV-4.1計算沖壓力、壓力中心、初選壓力機............................................144.1.1計算毛坯尺寸.............................................................................144.1.2計算落料沖裁力.........................................................................144.1.3計算拉深力.................................................................................144.1.4壓力機選擇.................................................................................154.1.5確定壓力中心.............................................................................154.2凸模與凹模刃口尺寸的確定.......................
