Xa abantu abaninzi besiva 'utyalo-mali olungenaziphene', baba nomfanekiso wecandelo elingenasiphako, elibengezelayo eliphuma ngqo kwincwadana. Inyani, ukugaya imihla ngemihla ukwenza ukuba kusebenze, kuninzi kwaye kunomdla ngakumbi. Ayikokunyibilikisa isinyithi kuphela kwaye uyigalele kwisingundo esihle; luthethathethwano oluthe gqolo phakathi kokuziphatha kwezinto, ijometri, kunye neendleko, apho isigqibo sobukhulu bodonga lwe-0.5mm sinokwenza okanye siphule iprojekthi. Ndibone uyilo oluninzi lungena olulungele ukwenziwa ngoomatshini kodwa iphupha elibi lokuphosa, kwaye kulapho incoko yokwenyani iqala khona.
Umdlalo weShell: Konke KukuMngundo
Iqokobhe liyinto yonke. Nantso into yokuqala oyifundayo. Sithetha malunga nokungunda kweqokobhe leceramic eyakhelwe malunga nepateni yewax. Inani leengubo, i-viscosity ye-slurry, i-stucco sand grit-isinyathelo ngasinye siguquguqukayo. Yenza impazamo, kwaye uya kubona iziphene ezifana nokungena kwentsimbi, apho intsimbi ingena ngokoqobo kwiqokobhe, ishiya indawo erhabaxa, edityanisiweyo eyiphupha elibi lokucoca. Ndikhumbula ibhetshi ye-316L yemizimba yevalvu esasiyibaleka; amanqaku okuqala aphuma kunye ne-gritty texture kwiindinyana zangaphakathi. Umoni? Uluhlu oluphambili lwe-slurry lwaluncinci kakhulu, kwaye isanti ecocekileyo ye-stucco ayizange idale ngokwaneleyo umqobo. Sihlengahlengise ixesha lokuntywila kwaye satshintshela kwisanti ye-zircon erhabaxa kwidyasi yokuqala yokugcina. Ingxaki yasonjululwa, kodwa yasixabisa iveki.
Kulapho amava e-Foundry ebonisa khona. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), kunye namashumi eminyaka kumdlalo, le nkqubo ifakiwe. Ayingomlingo; nguvimba weenkcukacha wokusilela kunye nolungiso olwakhiwe kwiminyaka engama-30. Awukwazi ukukhawuleza ixesha lokumisa phakathi kweengubo, kungakhathaliseki ukuba ishedyuli yokuvelisa ithini. Ukufuma kuba lutshaba lwakho okanye umhlobo wakho.
Kwaye umthwebeba asiyo-wax nje. Iiparamitha ze-injection zepatheni yokuqala-uxinzelelo, ukushisa-kuchaphazela ukuzinza kwayo kwe-dimensional. Ipateni yewax ejike kancinane iguqulela ngokuthe ngqo kwiqokobhe leceramic elijijekileyo, kwaye emva koko libe yinxalenye yentsimbi engaphandle kwe-Special. Sichitha ixesha elininzi lokufaneleka inkqubo ye-wax njengoko senza ukugalela isinyithi. Sisiseko esingenabubele, esibalulekileyo.
Isixhobo asiloPhepha nje eliKhethekileyo
Ukuchaza i-CF8M okanye i-17-4 PH sisiqalo nje sompu. Inkqubo yokunyibilika kulapho kwenzeka khona isinyithi. Ukuphosa utyalo-mali, ujongene nobushushu obuncinci, ngoko ke ulawulo lubalulekile. Ukuziqhelanisa ne-aluminiyam okanye isilicon? Itshintsha i-fluidity kunye nomxholo wokugqibela wokubandakanywa. Kwiindawo ezinoxinzelelo, obu bubomi okanye ukufa.
Thatha i-17-4 PH insimbi engenasici. Ibakala elidumileyo lemvula-ukuqina. I-advanteji yokuphosa utyalo-mali kukuba ungafezekisa ukugqiba okumangalisayo komgangatho wokuphosa kunye neemilo ezinzima. Kodwa unyango lobushushu imeko H900? Ukuba isisombululo se-annealing asenziwanga ngokugqibeleleyo ngokufanayo, uya kufumana iimpawu zomatshini ezingahambelaniyo. Ndibone amakhuphoni ovavanyo oluqinileyo ukusuka kwibhetshi yokuphosa efanayo ebonisa i-50 ksi esasazwa ngamandla esivuno ngenxa yokuba umthwalo weziko wawungacwangciswanga kakuhle. Inxalenye yayibonakala igqibelele, kodwa yayiza kusilela enkonzweni.
Le yenye indawo apho ukusebenzisana neengcali kuhlawula. I-Foundry eyenza ngaphakathi endlwini CNC Machining, njenge-QSY, inenzuzo enkulu. Bayaqonda ukuba i-microstructure ye-casting kunye ne-micro-porosity enokubakho iya kusebenzisana nesixhobo sokusika. Banokuluhlengahlengisa unyango lobushushu ukuze baphucule ubuchule ngaphandle kokuncama iipropathi zokugqibela, into enokuthi ingaqwalaselwa yindlu ezimeleyo yokuphosa. Yimbono epheleleyo yomjikelo wobomi wecandelo.
Ijometri: Inkululeko kunye nomgibe
Ewe, ukuphoswa kotyalo-mali kukunika inkululeko engakholelekiyo yejometri. Iindinyana zangaphakathi, i-undercuts, i-curves eyinkimbinkimbi-konke kunokwenzeka. Kodwa 'inokwenzeka' ayithethi 'kulula' okanye 'indleko eyongayo'. Umgaqo wobhontsi bubunzima obufanayo bodonga. Kodwa kwihlabathi lokwenyani, iinxalenye zifuna iimbambo, abaphathi, kunye neepads zokukhwela. Umceli mngeni kukulawula umahluko we-thermal mass.
Ukusilela okuqhelekileyo kukucutheka kwe-porosity kwindawo eshushu. Yiba nomfanekiso wendlu yevalve eneflange eshinyeneyo itshintshela kumzimba obhityileyo. Icandelo elibhityileyo liyaqina kuqala, lihlukanise i-flange eshinyeneyo, ethi emva koko icuthe njengoko iphola kungekho mthombo wentsimbi engamanzi ukuyondla. Isiphumo? Indawo ethambileyo, ebuthathaka kanye apho ufuna khona amandla. Ulungiso? Ukusetyenziswa okuchuliweyo kwengqele (ukufakwa kwesinyithi kwiqokobhe ukukhupha ubushushu) okanye i-wax padding ukudala ubunzima obongezelelweyo obuthi bucinywe kamva. Yiphazili.
Ndasebenza kwi-impeller yepompo kanye, zonke ezicekethekileyo, iincakuba ezimile okwe-aerofoil. Ingxaki yayingezizo iincakuba; ibiyindawo esembindini. Yayinkulu kakhulu xa ithelekiswa neencakuba. Siye sagqiba ukongeza isiseko se-ceramic kwi-hub ukuze siyenze ibe holo, sinciphisa ubunzima be-thermal kunye nokudala imeko yokupholisa efanayo. Utshintsho loyilo lwaluqhutywa yinkqubo yokuphosa, kungekhona enye indlela. Iphumelele loo nto utyalo mali.
Umgca wokugqibezela awusoze waba linyathelo nje elinye
I-Knock-off, i-cut-off, i-grilling, i-shot blasting, unyango lobushushu, i-pickling ... amanyathelo emva kokuphosa apho iindleko kunye nomgangatho unokwahluka kakhulu. Wonke umntu ufuna indawo ekulungeleyo ukuyifaka, kodwa loo nto ilungile ineeleya.
Ukusikwa bubugcisa. Ukususa inkqubo yokukhangela (iitshaneli ezondla isinyithi kwindawo) ngaphandle kokonakalisa icandelo. Ukusebenzisa amavili abrasive kudala ubushushu, obunokuchaphazela i-metallurgy kwindawo echaphazelekayo kubushushu, ngakumbi kumabakala anzima. Iindawo eziphucukileyo ngakumbi zisebenzisa iisarha zebhendi okanye nokuba CNC Machining ukususa amasango ngokuchanekileyo. Intsalela yesango ke kufuneka igungxulwe phantsi. Lo ngumsebenzi wezandla, onezakhono. Umgangatho wolu kugqiba uchaphazela ngokuthe ngqo ubomi bokudinwa ukuba isango likwindawo yoxinzelelo oluphezulu.
Pickling, iasidi bath ukususa isikali kunye nokubuyisela i-chromium oxide layer kwi intsimbi engenasici umphezulu, lelinye inyathelo elibalulekileyo. Ixesha, ubushushu, i-acid concentration-konke kufuneka kulawulwe. I-pickle engaphezulu, kwaye ufumana indawo edibeneyo, enemingxuma. Ngaphantsi kwepickle, kwaye ushiya isikali esizinzisiweyo esinokuqalisa ukubola. Sisenzo sokulinganisa imichiza esingafumani ngqalelo yaneleyo de kuphume into ejiyileyo okanye inomhlwa ejonge ngqo ebhafini.
Kutheni iqabane eliLungileyo lingengoMboneleli nje
Eli ayiloshishini lorhwebo. Awuthengi izinto zokuqhobosha ngaphandle kweshelufu. Uthenga isakhono senkqubo kunye nobunzulu bokusombulula ingxaki. Xa ujonga imvelaphi yenkampani, njengokubona oko QSY ibisebenza ngaphezulu kweminyaka engama-30 kulo lonke uphononongo kunye noomatshini, ikuxelela ukuba bakhe bajongana nolu rhwebo kwizizukulwana zeenjineli. Mhlawumbi baye bagcina iiprojekthi ngokucebisa i-engile eyidrafti encinci yokutshintsha okanye ibakala elahlukileyo lealloyi elidlala ngcono ngeepropati ezifanayo.
Elona xabiso likhulu i-Foundry elungileyo ibonelela kungenelelo loyilo lwangethuba. Ngaphambi kokuba imodeli yeCAD igqitywe, ngaphambi kokuba isixhobo sinqunywe. Kulapho banokuthi, Singayiphosa loo nto, kodwa ukuba uyasivumela ukuba sijikeleze esi sidibaniso kancinci, siqinisekisa ukuba akukho kuncipha, okanye Qwalasela ingxubevange esekwe nickel apha endaweni yoko; iyakuxhathisa loo meko-bume ebolileyo ngcono kwaye sineresiphi eqinisekisiweyo yeqokobhe layo. Le ntsebenziswano ijika umzobo ube yinto enokwenziwa, ethembekileyo.
Ekugqibeleni, uphumelele steel stainless utyalo lokugalela imalunga nokwamkela imiqobo yenkqubo yokuvula isakhono sayo. Yincoko phakathi kwenjongo yoyilo kunye nenyani ebonakalayo. Inxalenye emenyezelayo, nentsonkothileyo ekwidesika yenjineli ibangelwe yikhulu lezigqibo ezincinane nezichanekileyo—kunye neempazamo ezimbalwa ezilungisiweyo—ezenziwe kwisiseko, kwakudala ngaphambi kokuba intsimbi igalelwe. Yiloo nto utyala kuyo ngokwenene.
