Xa abantu abaninzi besiva 'i-aluminiyam yokuphosa isanti', baba nomfanekiso wenkqubo elula, phantse yakudala-balahla isinyithi esityhidiweyo kwisingundo sesanti, siyipholise, kwaye ugqibile. Leyo yeyona mbono iphosakeleyo. Inyani luthethathethwano oluthe gqolo phakathi kwe-fluidity ye-aluminiyam kunye nenkani yesanti, apho impumelelo ixhomekeke kwiinkcukacha ezininzi ze-spec sheet azizange zikhankanye. Asiyondlela yokuphosa nje; luludwe lwezivumelwano ezibaliweyo.
Isanti Ayingobumdaka nje, kwaye iAluminiyam ayiyoNtsimbi nje
Makhe sithethe ngesanti kuqala. Isanti eluhlaza, i-resin-bonded, i-sodium silicate-ngamnye unobuntu bakhe. Kumsebenzi wealuminiyam jikelele, umxube wentlabathi eluhlaza kunye nodongwe olufanelekileyo kunye nolawulo lokufuma lihashe lomsebenzi. Kodwa ndibone iiprojekthi zisilela kuba umntu uphathe inkqubo yesanti njengesithako esimileyo. Yinkqubo ephilayo. Isanti iphinda isetyenziswe, kodwa ithotywa, ithatha izinto ezingcolisayo kwi-binder burnout, kunye nokungena kwayo kuyatshintsha. Ukuba awuyijongi ibhetshi yeepropathi zayo ukuba ibhetshi, uyakuqala ukufumana iziphene ezingaphezulu, njengokubhula okanye imisila yeempuku, ekhangeleka njengemiba yentsimbi kodwa iyingxaki yesanti.
Emva koko kukho i-aluminiyam. 'Ialuminiyam' ibanzi kakhulu. Ngaba sithetha nge-A356 ngokugqwesa kwayo okugqwesileyo kunye nokunyangeka kobushushu? Okanye mhlawumbi i-6061 yemfuno ethile yobuchule, nangona kunzima ukuyiphosa? Ukhetho luyalela yonke into-iqondo lobushushu lokuthulula, uyilo lwenkqubo yokungena, ukuncipha kokuqina. Ukugalela i-A380 ngexesha elifanayo ne-A356 yindlela yokupheka i-porosity. I-alloy iyalela umdaniso.
Apha kulapho amava avela kwivenkile ethengisa inkonzo epheleleyo abaluleke kakhulu. Indawo efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye namashumi eminyaka yabo ekubumbeni nasekusebenzeni, ifumana le ntsebenziswano. Abayi kujonga nje umzobo wezindlu ze-aluminiyam; baya kuqwalasela lonke uhambo ukusuka kwintsimbi etyhidiweyo ukuya ekugqibeleni, inxalenye yomatshini. Inkqubo yokuphosa isanti ibeka inqanaba kuwo wonke umsebenzi we-CNC osezantsi. Inxalenye ephoswe kakubi ngokushwabana kwangaphakathi okanye amabala aqinileyo aya kubulala izixhobo ngexesha lomatshini, ixabiso elihlala lingahoywa kwiikowuti zokuphosa ezitshiphu.
Ukugada, uKutyisa, kunye nobuGcisa bokuManyaniswa koMkhombandlela
Le yintliziyo yayo. Unokuba nesanti egqibeleleyo kunye ne-alloy egqibeleleyo, kodwa ukuba inkqubo yakho yokungena kunye nokunyuka (yokutya) yinto yokucinga emva koko, uya kuyilahla inxalenye. Injongo kukuqiniswa kwecala: ukwenza isinyithi siqine ukusuka kweyona ndawo ikude yokuphosa ngasemva ukuya kwisikhuphukeli, esiyindawo yokugcina isinyithi eshushu esondla ukushwabana. Kwi-aluminiyam, oku kubalulekile kuba izinga lokucutheka libalulekile.
Ndifunde oku ngendlela enzima kwangethuba ngesibiyeli sempompo esibiyelweyo. Ukuphosa kwakukhangeleka kuvakala, kodwa ngexesha lovavanyo loxinzelelo, kuye kwavuza. Ukwahlulahlula kuveze iziko elinesiponji le-micro-shrinkage porosity. Ingxaki? Isikhuphukeli sasincinci kakhulu kwaye sibekwe ngokungalunganga; yomelela phambi kokuba icandelo elishinyeneyo lesibiyeli lenze, ngoko kwakungekho ntsimbi engamanzi ishiyekileyo ukondla oko kushwabana. Ukulungiswa kwakungekokongeza nje isinyithi esingakumbi; yayiyila ngokutsha isango lokulawula ukuthambeka kwe-thermal. Sasebenzisa iingqele—ukufakwa kwentsimbi esantini—ukuze sikhawuleze ukupholisa kwiindawo ezithile size sinyanzelise ukuqina kwicala elifanelekileyo.
Ukulinganisa isoftware kuyanceda ngoku, kodwa ayiyovangeli. Ikunika umkhwa, uqikelelo. Usadinga ukuyitolika ngolwazi olusebenzayo. Ngamanye amaxesha, ukulinganisa kubonisa indawo eshushu, kwaye incwadi ithi yongeza i-riser apho. Kodwa ukuba loo ndawo ikwiwebhu ecekethekileyo, ukongeza isinyusi esikhulu kukugqithisela kwaye kudala umthwalo omkhulu womatshini. Mhlawumbi isisombululo esingcono kukutshintsha kancinci uyilo lwenxalenye kunye nomthengi, ukongeza ubambo oluncinci ukusabalalisa kwakhona ubunzima. Olo luhlobo lobunjineli bexabiso eliziswa liqabane elinamava.
Apho iSanti iphosa khona imida yayo (kwaye apho ikhanya khona)
I-aluminiyam yokugalela isanti ilungile kumthamo ophantsi ukuya phakathi, kumalungu amakhulu, kunye noyilo oluya kuba yindleko ephantsi ukuya kumatshini osuka kwibillet eqinileyo. Cinga iibhloko zenjini, iimeko zothumelo, izakhelo ezinkulu zesakhiwo. Isiphelo somphezulu asiyi kuba mtyibilizi njengokuphosa kotyalo-mali okanye ukuphosa ukufa, kwaye ukunyamezelwa kwe-dimensional kubanzi. Urhweba ngokuchaneka okuthile ukuze ube bhetyebhetye kunye nexabiso eliphantsi lezixhobo.
Kodwa umda abukho nje ubukhulu okanye ukunyamezela. Kubunzima bejometri. Iipokotho ezinzulu, ezimxinwa? Iindlela zangaphantsi? La ngamaphupha amabi kubumba olulula lwesanti enamacandelo amabini. Uqala ukongeza ii-cores-iimilo zesanti ezahlukileyo ezifakwe kwi-mold. Undoqo ngamnye wongeza iindleko, ukuntsonkotha, kunye nomthombo omtsha weziphene ezinokuthi zibekho (ezifana nokutshintsha okungundoqo okanye irhasi esuka kwi-core binder). Ndikhumbula iprojekthi yombutho wevalvu oxandileyo apho indibano engundoqo yayinamacandelo amathandathu awahlukeneyo. Izinga lesivuno lalibi kakhulu de satshintsha i-core binder material ukuya kwenye evelisa igesi encinci kwaye yandisa imilinganiselo yoshicilelo oluphambili (amanqaku okubhalisa) ukuzinza okungcono.
Yiyo loo nto iinkampani ezibonelela ngoluhlu lweenkqubo, njenge-QSY kunye neqokobhe labo lokungunda kunye nesakhono sokuphosa utyalo-mali, zinenzuzo. Bangajonga indawo ethile kwaye ngokunyanisekileyo bathi, Kule geometry kunye nokugqitywa komphezulu ofunekayo, ukujulwa kwesanti akulunganga. Ukwenziwa kotyalo-mali kunokongela iindleko zizonke ngokunciphisa umatshini. Olo sukelo lubalulekile.
IHandoff eBalulekileyo: As-Cast to Machined
Ukusaswa akuyonxalenye egqityiweyo. Phantse rhoqo, ifuna ukwenziwa ngoomatshini. Ubudlelwane phakathi kwe-Foundry kunye nevenkile yomatshini ayinakuba yintshatsheli. Ingcali yoomatshini kufuneka iqonde i-quirks-njenge-engile yokuyila encinci ebusweni obuthe nkqo, ukubakho kweendawo eziqinileyo kufutshane nengqele, okanye isibonelelo sesitokhwe esingafananga. I-Foundry kufuneka iqonde ukuba yintoni efunwa ngumachini: imiphezulu yedatha engaguqukiyo, isitokhwe esaneleyo sokucoca, kunye nokuthintela iziphene kwiindawo ezibalulekileyo.
Imisebenzi edibeneyo iyayicombulula le nto. Ukuba inkampani efanayo egalela ukugalela nayo iyayenza, njenge CNC Machining iinkonzo kwi QSY, iluphu yengxelo iqinile. Iqela lomatshini lixelela isiseko, Sibona ukunxitywa kwezixhobo rhoqo xa sifika kwesi sidibaniso. I-Foundry inokuphanda-mhlawumbi kukubandakanywa kwe-alumina, mhlawumbi sisiphumo sendawo ebandayo-kwaye ulungelelanise inkqubo. Le synergy yindlela ofumana ngayo ukuthembeka. Ijika icandelo elifunyenweyo libe sisisombululo esenziweyo.
Ndikhe ndakwiiprojekthi apho umboniso wafunyanwa kumthengisi omnye kunye nomatshini komnye. Ukukhombana ngomnwe xa ibhetshi ingaphumelelanga yayingenasiphelo. Ngaba yayisisiphene sokuphosa okanye impazamo yobuchwephesha? Umnikezeli odibeneyo ungumnikazi wenkqubo yonke, kwaye uxanduva luguqulela kumgangatho.
Izinto eziphathekayo ayisiyiQithi: Xa iAluminiyam ayiyonelanga
Ekugqibeleni, cinga ngezinto eziphathekayo. Ngelixa sigxile kwi-aluminiyam, isiseko esihle asicingi kwiisilos. Ngamanye amaxesha, into eqala njengokuphosa kwesanti ye-aluminiyam iyaguquka. Mhlawumbi inxalenye idinga ukumelana namaqondo obushushu aphezulu okanye umhlwa ngaphezulu. Ukuba nobuchule kwezinye izinto, njengensimbi engenasici kunye ne-alloys ekhethekileyo (i-nickel-based, i-cobalt-based) eluhlu lwe-QSY, inika imbono ebanzi. Basenokucebisa ukuba kumphezulu othile onxitywe phezulu kwindawo ethile ye-aluminiyam, i-alloy efakwe eyahlukileyo inokuphoswa okanye yenziwe ngoomatshini kamva. Imalunga nokuba ne-toolkit epheleleyo yokusombulula ingxaki yokusebenza komxhasi, hayi isicelo sabo esichaziweyo senkqubo.
Ke, i-aluminiyam yokuphosa isanti? Yintsimi enzulu ngenkohliso. Imalunga nokulawula impatho yesanti, ukwalathisa ukuqina kwesinyithi esishwabeneyo, ukuyilwa kokwenziwa kwasekuqaleni, kunye nokuqinisekisa ukuba indawo ephoswe ngesanti isandulela esigqibeleleyo sohlobo lwaso lokugqibela lomatshini. Imdaka, iyasebenza, kwaye igcwele izinto eziguquguqukayo. Kodwa xa yonke icofa, kwaye utsala isandi, ukuphosa okucocekileyo kwisanti, ukulungele ukwenziwa komatshini ochanekileyo, yintlawulo yokwenyani leyo. Asiyonto yakudala; isisiseko.
