Umngundo sisixhobo esisisiseko senkqubo yoshishino lweemoto.Ngaphezulu kwe-90% yamacandelo kunye namacandelo kwimveliso yemoto kufuneka yenziwe ngumbumba.Ngokutsho kukaLuo Baihui, ingcali yokubumba, malunga ne-1,500 i-molds iyadingeka ukwenza imoto eqhelekileyo, apho i-stamping molds engaphezu kwe-1,000 isetyenziswa.Ekuphuhlisweni kweemodeli ezintsha, i-90% yomsebenzi wenziwa malunga nokutshintsha kweprofayili yomzimba.Ngokumalunga ne-60% yeendleko zophuhliso lweemodeli ezintsha zisetyenziselwa ukuphuhliswa kwemizimba kunye neenkqubo zestampu kunye nezixhobo.Malunga ne-40% yeendleko zokwenziwa kwesithuthi ziindleko zokutywinwa kwamalungu omzimba kunye nokuhlanganisa.
Kuphuhliso lweshishini lokubumba iimoto ekhaya nakwamanye amazwe, itekhnoloji yokubumba ibonise ezi ndlela zilandelayo zophuhliso.
1. Ukulinganisa inkqubo yesitampu (CAE) ivelele ngakumbi
Kwiminyaka yakutshanje, ngophuhliso olukhawulezayo lwesoftware yekhompyuter kunye nehardware, itekhnoloji yokulinganisa (CAE) yenkqubo yokwenza isitampu idlala indima ebaluleke kakhulu.Kumazwe ahambele phambili njengeUnited States, iJapan, kunye neJamani, itekhnoloji yeCAE iye yaba yinxalenye eyimfuneko yoyilo lokungunda kunye nenkqubo yokuvelisa.Isetyenziselwa ngokubanzi ukuqikelela ukwenza iziphene, ukunyusa inkqubo yesitampu kunye nesakhiwo sokubumba, ukuphucula ukuthembeka koyilo lokubumba, kunye nokunciphisa ixesha lovavanyo lokubumba.Iinkampani ezininzi zokubumba iimoto zasekhaya ziye zenza inkqubela ebonakalayo ekusetyenzisweni kwe-CAE kwaye zafumana iziphumo ezilungileyo.Ukusetyenziswa kwetheknoloji ye-CAE kunokugcina kakhulu iindleko zokubunjwa kovavanyo kunye nokunciphisa umjikelezo wophuhliso lwe-stamping molds, eye yaba yindlela ebalulekileyo yokuqinisekisa umgangatho wokubumba.Itekhnoloji ye-CAE ngokuthe ngcembe iguqula uyilo lokungunda ukusuka kuyilo olusebenzayo ukuya kuyilo lwenzululwazi.
2. Isikhundla soyilo lwe-3D lokubumba ludityanisiwe
Uyilo lwe-mold-dimensional three-dimensional yinxalenye ebalulekileyo yeteknoloji ye-digital mold kunye nesiseko sokuhlanganiswa koyilo lokubumba, ukuveliswa kunye nokuhlolwa.Iinkampani ezifana neToyota kunye neGeneral Motors yaseUnited States ziye zaqaphela uyilo olunemigangatho emithathu yokubumba kwaye zafumana iziphumo ezilungileyo zesicelo.Ezinye iindlela ezamkelwe kuyilo lokungunda lwe-3D phesheya zifanelekile ukuba sibhekise kuzo.Ukongezelela ekufezekiseni ukuveliswa kwemveliso edibeneyo, i-design-dimensional dimensional ye-mold inenye inzuzo yokuba ilungele ukuhlolwa kokuphazamiseka kwaye inokwenza uhlalutyo lokuphazamiseka kwentshukumo, eyisombulula ingxaki kwi-design-dimensional design.
Okwesithathu, itekhnoloji yokubumba idijithali iye yaba yeyona ndlela iphambili
Kwiminyaka yakutshanje, uphuhliso olukhawulezayo lwetekhnoloji yokubumba idijithali yindlela esebenzayo yokusombulula iingxaki ezininzi ezijongene nophuhliso lokubumba iimoto.I-teknoloji ebizwa ngokuba yi-digital mold technology kukusetyenziswa kweteknoloji yekhompyutheni okanye iteknoloji yokuncedisa ikhompyutha (CAX) kuyilo lokubumba kunye nenkqubo yokuvelisa.Ukushwankathela amava aphumeleleyo eenkampani zokubumba iimoto zasekhaya nezangaphandle ekusebenziseni itekhnoloji encediswa yikhompyuter, itekhnoloji yedijithali yokubumba itekhnoloji ibandakanya ikakhulu le miba ilandelayo: ① Uyilo lokwenziwa kwezinto (DFM), oko kukuthi, ukwenziwa kuqwalaselwa kwaye kuhlalutywe ngexesha loyilo ukuqinisekisa impumelelo. yenkqubo.②Itekhnoloji encedisayo yoyilo lweprofayile yokubumba, phuhlisa itekhnoloji yoyilo olukrelekrele lweprofayile.③CAE inceda kuhlahlelo kunye nenkqubo yokwenza isitampu, ukuqikelela nokusombulula iziphene ezinokwenzeka kunye nokwenza iingxaki.④ Faka enye indawo yoyilo lwemveli olumacala mabini ngoyilo lokubumba olunemilinganiselo emithathu.⑤Inkqubo yokuvelisa i-mold yamkela i-CAPP, i-CAM kunye ne-CAT iteknoloji.⑥ Phantsi kokhokelo lwetekhnoloji yedijithali, jongana kunye nokusombulula iingxaki ezivela kwinkqubo yovavanyo lokungunda kunye nokuveliswa kwesitampu.
Okwesine, uphuhliso olukhawulezayo lwe-automation processing mold
Itekhnoloji yokuqhubela phambili kunye nezixhobo zisisiseko esibalulekileyo sokuphucula imveliso kunye nokuqinisekisa umgangatho wemveliso.Kuqhelekile ukuba iinkampani zokubumba iimoto eziphambili zibe nezixhobo zoomatshini be-CNC ezineetafile ezimbini zokusebenza, iziguquli zezixhobo ezizenzekelayo (ATC), iinkqubo zolawulo lweefoto zombane zokusetyenzwa ngokuzenzekelayo, kunye neenkqubo zokulinganisa i-workpiece ye-intanethi.Ukusetyenzwa kokulawulwa kwamanani kuye kwaphuhliswa ukusuka kwiprofayili elula yokwenziwa kweprofayili ukuya kwiprofayili ebanzi kunye nemiphezulu yesakhiwo, ukusuka kwisantya esiphakathi kunye nesantya esisezantsi ukuya kwisantya esiphezulu, kwaye uphuhliso lwetekhnoloji ye-automation ikhawuleza kakhulu.
5. Itekhnoloji yentsimbi yokubethela itekhnoloji ephezulu yamandla lukhokelo lophuhliso lwexesha elizayo
Amandla aphezulu ensimbi aneempawu ezibalaseleyo ngokubhekiselele kumlinganiselo wesivuno, iimpawu zokuqina koxinzelelo, amandla okusasaza ubunzima, kunye nokufunxa amandla okungqubana, kunye nomthamo wokusetyenziswa kwiimoto uyaqhubeka nokukhula.Okwangoku, i-steel-high-high-high-steel esetyenziswa kwi-automotive stampings ibandakanya insimbi yokuqinisa ipeyinti (BH steel), intsimbi ye-double-phase (DP steel), kunye ne-phase transformation induced plasticity steel (TRIP steel).Iprojekthi ye-International Ultra Light Body Project (ULSAB) iqikelela ukuba i-97% yemoto yengqondo ehamba phambili (ULSAB-AVC) eqaliswe kwi-2010 iya kuba yintsimbi ephezulu.Ubungakanani bentsimbi ephezulu ephezulu kwisixhobo sesithuthi siya kudlula i-60%, kwaye i-double-phase I-proportion yensimbi iya kuba ne-74% yeeplate zensimbi zemoto.Uluhlu oluthambileyo lwensimbi olusetyenziswa kakhulu kwi-IF insimbi iya kuba yintsimbi yentsimbi ephezulu, kwaye i-high-high-high-alloy low-alloy steel iya kuba yintsimbi yesigaba sesibini kunye ne-ultra-high-strength steel plate.Okwangoku, ukusetyenziswa kweepleyiti zetsimbi ezikumgangatho ophezulu kwiindawo zemoto zasekhaya zilinganiselwe kwiindawo zesakhiwo kunye nemiqadi, kwaye amandla okuqina ezinto ezisetyenzisiweyo angaphantsi kwe-500MPa.Ke ngoko, ngokukhawuleza ukuqonda itekhnoloji yestampu yeepleyiti zentsimbi ezinokuqina okuphezulu yingxaki ebalulekileyo ekufuneka isonjululwe ngokungxamisekileyo kwishishini lokungunda lelizwe lam.
6. Iimveliso ezintsha zokungunda ziya kuqaliswa kungekudala
Ngophuhliso olusebenzayo oluphezulu kunye ne-automation yemveliso yesitampu semoto, ukusetyenziswa kokufa okuqhubelekayo kwimveliso yeendawo zesitampu semoto kuya kuba banzi.Amacandelo estamping emilo entsonkothileyo, ngakumbi amanye amacandelo amancinci naphakathi antsonkothileyo afuna iiseti ezininzi zokubetha ngokufa ngokwenkqubo yemveli, ziya zikhula ngokufa okuqhubekayo.I-Progressive die luhlobo lwemveliso ye-high-tech mold, enzima ngokobuchwephesha, ifuna ukuchaneka okuphezulu kwemveliso, kwaye inomjikelezo omde wemveliso.I-multi-station progressive die iya kuba yenye yezona mveliso zibalulekileyo zokungunda kwilizwe lam.
Isixhenxe, izixhobo zokubumba kunye neteknoloji yonyango lomphezulu ziya kusetyenziswa kwakhona
Umgangatho kunye nokusebenza kwezinto zokubumba zizinto ezibalulekileyo ezichaphazela umgangatho wokubumba, ubomi kunye neendleko.Kwiminyaka yakutshanje, ukongeza kwintshayelelo eqhubekayo ezahlukeneyo ukuqina eliphezulu kunye nokumelana eliphezulu banxibe ukuxhathisa abandayo umsebenzi die steels, ilangatye kwacima abandayo umsebenzi die steels, kunye metallurgy umgubo umsebenzi obandayo steels die, kuyancomeka ukusebenzisa izinto ezityhidiweyo yentsimbi enkulu. kwaye ukunyathela okuphakathi kufela ngaphandle.Ixhala malunga nendlela yophuhliso.Intsimbi ye-nodular cast inokuqina okulungileyo kunye nokumelana nokunxiba, ukusebenza kwayo kwe-welding, ukusebenza, ukusebenza kokuqina komphezulu kukwalungile, kwaye ixabiso liphantsi kune-alloy cast iron, ngoko ke isetyenziswa kakhulu kwi-automobile stamping.
8. Ulawulo lwezenzululwazi kunye nokwazisa lukhokelo lophuhliso lwamashishini okubumba
