Xa usiva 'umxhuzulane ufe umenzi wokuphosa', abantu abaninzi bafanekisela inkqubo elula: tyekisa ileli, vumela umxhuzulane wenze into yawo, kwaye kuphume inxenye. Leyo yimbono yokuqala ephosakeleyo. Umxhuzulane ngamandla, ngokuqinisekileyo, kodwa ubugcisa bokwenyani kukuyilo lokufa, ulawulo lwe-thermal, kunye nokwazi ialloys zakho ngaphakathi ngaphandle. Yinkqubo yokubumba esisigxina, eyahlukileyo kuxinzelelo oluphezulu lokuphosa ukufa okanye ukuphosa isanti, kwaye ixabiso layo likuphindaphinda kunye nomgangatho ophezulu wesinyithi kwizicelo ezithile. Ndikhe ndabona iivenkile ziqhwaba kunye ukungunda kwentsimbi ukuze kuqhutywe izibiyeli ze-aluminiyam kwaye ziyibiza ngokuba yi-gravity die casting. Ngokobuchwephesha, ewe, kodwa iziphumo ngokwemigaqo ye-porosity, ukugqitywa komphezulu, kunye nokungaguquguquki? Kulapho abavelisi bokwenene bazahlula khona.
Undoqo weNkqubo: ngumdlalo wobushushu
Nabani na unokufumana isinyithi kumngxuma. Ubugcisa bulawula indlela obuqina ngayo. Ngokuphosa umxhuzulane, awunalo uxinzelelo oluqatha, olunesiphithiphithi lwe-HPDC lokunyanzela-ukutya ukungunda. Uxhomekeke ekungeneni ngendlela eyiyo kunye noyilo lwesinyusi ukuze uqinisekise ukuqina, ukondla ukushwabana ukusuka kwezona ndawo zinzima ukubuyisela izinyusi. Ukuba ibhalansi yakho ye-thermal kwi-die ivaliwe-yithi, isiqingatha esinye sipholile ngokukhawuleza-ufumana i-shrinkage yangaphakathi okanye ukuvalwa okubandayo. Oku sikufunde kabuhlungu kwiprojekthi yokuqala yempompo yezindlu kwiA356 aluminiyam. Ijometri yayinobuqili, kunye neflange eshinyeneyo edityaniswe nomzimba omncinci. Uyilo lwethu lokuqala lokufa lwaluneendlela zokupholisa ezifanayo. Amalungu aphume ejongeka elungile, kodwa ukucwangciswa kwaveza i-porosity kubuso obutywiniweyo beflange. Ixabiso le-scrap lalingamkelekanga.
Oko kusilela kunyanzelise ukuntywila nzulu. Kuye kwafuneka sahlule i-die cooling, sifaka i-chilling enobundlobongela kwicandelo elishinyeneyo ukuze liqiniswe kuqala, livumela icandelo elincinci kunye nezinyusi ukuba zilondle. Kwathetha ulwakhiwo oluntsonkothileyo lwefa, oluneendlela ezahlukeneyo zombhobho wamanzi. Iindleko zinyukile, kodwa isivuno saphuma kwi-65% saya ngaphezulu kwe-95%. Leyo yinyani engathandekiyo: ukuba nobuchule Umxhuzulane kufa umenzi ukuphosa ayithethi ngokugalelwa; imalunga nokuqikelela nokulawula ukuhamba kobushushu ngokulinganisa isoftwe kuqala, emva koko ngobunjineli bokufa obucokisekileyo.
Oku kudibanisa ngokuthe ngqo kukhetho lwezinto eziphathekayo. Ngelixa ii-alloys ze-aluminiyam ezifana ne-A356 okanye i-A380 zixhaphakile, sisebenzise inkqubo kubhedu kunye neengxube ezithile ze-magnesium. Ngamnye uziphatha ngokwahlukileyo. I-alloys esekwe kwiCopper inoluhlu oluqinisiweyo oluncinci kakhulu, olunokuba yintsikelelo kunye nesiqalekiso-imfuneko encinci yokondla kodwa ithanda ukukrazuka okushushu ukuba umqobo wokungunda awulunganga. Awunakuthatha nje uyilo lokufa kwe-aluminiyam kwaye ugalele ubhedu kuyo. I-conductivity ye-thermal, i-shrinkage rate, yonke into iyatshintsha. Apha kulapho ubuchwephesha be-metallurgical Foundry, njengomsebenzi okudala umi kwifemu efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), iba ngogxekayo. Imvelaphi yabo kwiqokobhe kunye nokuphosa utyalo-mali ngeengxubevange ezahlukeneyo kuthetha isiseko senzululwazi esinzulu esazisa ngokuthe ngqo indlela yabo yokuphosa ukufa.
Apho Ingena khona (kwaye apho ingangeni khona)
Ukuphosa ukufa komxhuzulane akuyompendulo yayo yonke into. Umthamo sisihluzo esingundoqo. Kwimitsi emandla kumakhulu amawaka, isantya soxinzelelo oluphezulu siyaphumelela. Kwi-off-off okanye iibhetshi ezincinci, ukuphosa isanti kunexabiso eliphantsi kwisixhobo. Indawo eswiti yomxhuzulane idla ngokuba yimithamo ephakathi-amawaka ukuya kumashumi amawaka eenxalenye-apho ufuna iipropathi zoomatshini ezingcono kunye nokugqiba komphezulu kunokunikezelwa kwesanti, kodwa inxalenye yejometri okanye ialloy ayifanelanga i-HPDC. Cinga ngamacandelo okunqunyanyiswa kweemoto, izibiyeli ze-aerospace, okanye imizimba yevalvu ye-hydraulic.
Ndikhumbula iprojekthi yokufaka ubhedu kwizinga lolwandle. Inxalenye yayineepaseji zangaphakathi ezaziza kuba yinto ebuhlungu kwi-core kunye nesanti, kwaye iimfuno zokuxhathisa ukubola zikhupha ii-alloys ze-HPDC eziqhelekileyo. I-Gravity die casting yayiyeyona bhulorho ifanelekileyo. Singasebenzisa i-core complex, i-core yensimbi enokubuyiswa ukwenza iipaseji, kwaye ukuqina okulawulwayo kwasinika ubuninzi obufunekayo kumlinganiselo woxinzelelo. Umphezulu ogqityiweyo wawukufutshane-omatshini ngaphandle kokungunda, ukunciphisa ukusetyenzwa kwasemva. Nantso isiphakamiso sexabiso: ibhalansi yemfezeko, ukuntsonkotha, kunye neendleko.
Yingakho abaninzi abavelisi abadibeneyo, njenge-QSY, badibanisa iinkqubo. Indawo yabo (https://www.tsingtaocnc.com) ibonisa ukuba bayabamba iqokobhe ngundo ukuphosa kwaye utyalo mali ecaleni komatshini weCNC. Oku kuyaxela. Inxalenye inokuqala njengokuphosa umxhuzulane wokufa kumzimba ophambili, ibe notyalo-mali oluntsonkothileyo imilomo edityanisiweyo, emva koko uye kwi-CNC ukuze ukruquke kwaye uqhutyelwe. Umvelisi owenza inkqubo enye kuphela kufuneka abeke esichengeni uyilo. Umntu odityanisiweyo unokucebisa eyona ndlela ingumxube. Kumxhasi, oko kubaluleke kakhulu-iguqula umthengisi abe liqabane lezisombululo kunokuba nje ivenkile yemisebenzi.
I-Tooling Trap: Iindleko vs. Lifespan
Iindleko zezixhobo zezona zithintelo ezinkulu ekungeneni kwabathengi. I-gravity die yi-mold yentsimbi eyenziwe ngoomatshini, ehlala i-H13 okanye intsimbi efanayo eshushu, ephathwa ngobushushu. Ayitshiphu. Ndiye ndabanabathengi balk kwisicatshulwa sokuqala, bekhetha izixhobo zokugalela isanti ezinexabiso eliphantsi. Kodwa kufuneka uqhube amanani okuqhuba kwemveliso yonke. Ukufa komxhuzulane ogcinwe kakuhle kunokuhlala kuma-50,000, kunye ne-100,000 yokudutyulwa. Iindleko ngenxalenye nganye yezixhobo ziyancipha ngokukhawuleza. Ukugalelwa kwesanti kufuna ukungunda okutsha ngalo lonke ixesha-ipateni ihlala, kodwa umsebenzi kunye nemathiriyeli yesikhunta ngasinye ziyadibanisa.
Isondlo sesinye isiqingatha. Ukufa ayisosixhobo somlilo kunye nokulibala. Kufuneka ulawule ukudinwa kwe-thermal. Phakathi kwee-run, ngakumbi kwimveliso ephezulu, ifa kufuneka ihlolwe ukujonga ubushushu-ezo zintanda zincinci ziqala phezulu. Ukuba zifunyenwe kuselithuba, zinokucocwa. Ukuba akunjalo, baya ku-telegraph kwindawo yokuphosa kwaye ekugqibeleni bakhokelele ekungaphumeleli kwentlekele. Ulungile Umxhuzulane kufa umenzi ukuphosa iya kuba nerejimeni engqongqo kufa pre-ukufudumeza, isicelo ukutyabeka (ezo izitshizi ceramic akukhona nje ukukhululwa, bagqume umphezulu die), kunye nokupholisa post-run. Utyeshele oku, kwaye isixhobo sakho sexabiso eliphezulu siba sisisindi sephepha kwimijikelo engamawaka ambalwa.
Sakhe sathatha iprojekthi kumniki-nkonzo ongaphumelelanga. Iintsini zaziyingxubakaxaka, zigqunywe bubushushu obunzulu kunye nemigca egogekileyo yokwahlukana. Umxhasi ucinge ukuba banokusithumela izixhobo kwaye siqale. Kwafuneka sibe ngabathwali beendaba ezimbi: abaswelekileyo bafuna ukuvuselelwa okubalulekileyo, ngokusisiseko ukwakhiwa kwakhona kokufakwa kwecango. Yayisisifundo kwiindleko ezifihlakeleyo zokukhetha umenzi osekelwe kwixabiso leqhekeza yedwa, ngaphandle kokuhlolisisa inkcubeko yabo yokugcina izixhobo.
Ukudityaniswa noMatshini: Ikhonkco elingaxoxiswanga
Zimbalwa kakhulu iindawo eziphoswe ngomxhuzulane ezinokwakheka komnatha. Phantse zonke zifuna umatshini othile: ukujongana nemiphezulu yokutywina, ukugrumba kunye nemingxuma yokucofa, iibheringi ezikruqulayo. Kulapho inkqubo yokuphosa kunye nomatshini kufuneka kuyilwe ngokudibeneyo. Kulilize ukuvelisa ukuphosa okuhle ukuba iimpawu ze-datum zoomatshini azihambelani okanye ukuba inxalenye inoxinzelelo olushiyekileyo olukhutshwayo ngexesha lokusikwa, lubangele ukuba lujike.
Umsebenzi obalulekileyo kukumisela isibonelelo somatshini kumzobo. Le yimathiriyeli eyongezelelweyo eshiywe ebusweni obubalulekileyo kwi-CNC yokucoca. Isibonelelo esincinci kakhulu, kwaye usengozini yokuphuma kwindawo ephosiweyo ukuba kukho umahluko omncinci. Kakhulu, kwaye uchitha ixesha lomatshini kunye nobomi besixhobo. Ukufumana oku kuchanekileyo kufuna idatha yembali evela kwiindawo ezifanayo. Yinkqubo yokufunda ephindaphindwayo ngaphakathi kumzi-mveliso. Inkampani eneminyaka engama-30 ekusaseni nasematshinini, efana ne-QSY, ingadayilelwa oku. Isebe labo le-CNC ayiloqumrhu elahlukileyo; ikwingxelo eqhubekayo kunye ne-Foundry. Bayazi ukuba umgangatho wabo we-A356-T6, isibonelelo se-1.5mm ebusweni be-flange sikhuselekile kwaye sisebenza kakuhle.
Ukulungiswa komatshini yenye into eqwalaselwayo. Olona qheliselo lungcono kukuyila ukuphosa kucingelwa ngoomatshini. Ngaba sinokuphosa iilugi ezintathu ezincinci kubuso obungabalulekanga obunokusetyenziswa ukufumana kunye nokucinezela indawo kwi-CNC vise? Ezo lugs zicinywa kumatshini wokugqibela. Olu hlobo loyilo-lokwenza-ukwenziwa kokucinga yinto eyahlula umvelisi wamalungu kwiqabane lobunjineli. Xa ujonga amandla okusebenza okudibeneyo, ubukho bendlu CNC Machining ayisiyonkonzo yokongeza ixabiso; yimfuneko ebalulekileyo ekunikezelweni kwecandelo elisebenzayo, elichanekileyo.
Ukujonga kwiMetal: ii-alloys kunye neMfezeko
I-Gravity die casting ithanda iialloyi ezithile. Kwi-aluminium, i-silicon-modified alloys (efana ne-A356, i-A360) ilungile-i-fluidity enhle, amandla ahloniphekileyo, kunye nokuphendula kunyango lokushisa. Kodwa le nkqubo ikwavula iingcango zezixhobo ezikhethekileyo. Apha kulapho amava abanzi e-Foundry ahlawula izabelo. Qingdao Qiangsenyuan Technology Co., Ltd. izintlu zisebenza nge intsimbi engenasici kwaye ialloys ezikhethekileyo njenge-nickel-based kunye ne-cobalt-based. Ngelixa ezi ziqhele ukunxulunyaniswa neqokobhe labo okanye iinkqubo zokuphosa utyalo-mali, olo lwazi lwe-metallurgical ludlulisa.
Umzekelo, cinga ngesicelo sobushushu obuphezulu. Unokwenza iprototype kwi-aluminiyam eqhelekileyo yokuphosa umxhuzulane. Kodwa kwimveliso, unokufuna ukuvavanya i-alloy-based alloy ye-nickel ukumelana nokunyuka. Amaqondo obushushu okugalela aphezulu kakhulu, kwaye izinto zokufa kunye nokwaleka kufuneka zimelane naloo nto. Ukuziphatha kokuqina kwahlukile. Umenzi ongenalo la mava e-alloy uya kuqala ukusuka ku-zero. Omnye onembali kwii-alloys ezikhethekileyo, nangezinye iinkqubo, unolwazi olusisiseko malunga nendlela ezi ntsimbi ziziphatha ngayo-izinto zazo zokucutheka, ukuchaphazeleka kwazo kwi-oxidation, ubuchule bazo bokugalela obufanelekileyo. Oku kunciphisa umngcipheko wokuvavanywa kunye nempazamo kwiprojekthi entsha.
Ekugqibeleni, ukukhetha a Umxhuzulane kufa umenzi ukuphosa ayikokufumana nje umntu ophethe oomatshini. Imalunga nokuvavanya ubunzulu bazo kwiindawo ezintathu ezinxibeleleneyo: ubunjineli bokufa kunye nolawulo lwe-thermal, isayensi yezinto eziphathekayo, kunye nenkqubo ehlanganisiweyo yokuphosa. Inkqubo ihleli kumdibaniso onomdla wobugcisa kunye nefiziksi elawulwayo. Xa yenziwe ngokufanelekileyo, ivelisa iinxalenye ezinokuthembeka okuthe cwaka—ezixineneyo, ezivakalayo, nezisoloko zisenziwa. Xa kusondela njengokugalela nje isinyithi, yindlela ekhawulezayo yokulahla iimfumba kunye neenjineli ezidanileyo. Umahluko kwiinkcukacha, amashumi eminyaka e-nuance eqokelelweyo, kunye nengqondo ejonga isikhunta kunye nesinyithi njengenkqubo enye, eguquguqukayo ekufuneka iphathwe.
