Uva 'ilahleko yotyalo-mali olulahlekileyo' kwaye uninzi lwabantu, nkqu nabanye kurhwebo, bafanekisela le nkqubo ingenasiphako, phantse yomlingo apho ugalela isinyithi kwiqokobhe leceramic kwaye ufumane indawo egqibeleleyo. Leyo yinguqulelo yencwadana. Okwenyani, ukugawula kwemihla ngemihla, kukuxoxisana rhoqo kunye nezinto eziguquguqukayo-ukubunjwa kwe-wax, i-slurry viscosity, ubukhulu bengqolowa ye-stucco, iindlela zokukhupha i-dewaxing, ukushisa kwe-preheat. Kuncinci malunga nokulandela iresiphi egqibeleleyo kwaye ngaphezulu malunga nokwazi ukuba leliphi iqhosha elijikayo xa ukufuma kunyuka okanye ibhetshi entsha yesibophelelo iyasebenza. Indawo 'elahlekileyo' ayikho malunga nokunyamalala komthwebeba; imalunga neeyure ezingenakubalwa zenkqubo yokuguqula into engazange ifike kwiphepha elithile.
ISiseko: Yonke Iqala (kwaye inokuphela) ngePhatheni
Wonke umntu ucinga ngesinyithi, kodwa eyona ndawo yolawulo yipatheni ye-wax. Sasidla ngokucinga ukuba nayiphi na iwax yesitofu iya kwenza, ukuba nje izalise umngundo. Impazamo enkulu. Ipateni enoxinzelelo lwangaphakathi okanye ukuphambuka okuncinci kuya kuphinda-phinda eso siphene ngokuthembekileyo kwinyathelo ngalinye elilandelayo, iphele njengokuphosa okune-dimensional drift akukho sixa somatshini esinokulungiswa ngokupheleleyo. Ndikhumbula ibhetshi yemizimba yevalvu esasiyiqhubela umxhasi, apho iipateni zazijongeka zigqibelele emehlweni. Kodwa ngexesha lokuhlanganisana, amazibuko awayi kulungelelaniswa. Umoni? Umxube wewax wawuthambile kakhulu kwigumbi lethu elilawulwa yimozulu kuloo veki; iipateni ziye zawa ngobuncinci phantsi kobunzima bazo emthini. Ugalele yonke into yayingamabhodlo. Ngoku, sinenzondelelo yempambano malunga nokuhlolwa kwepateni, sisebenzisa umlinganiso wolungelelwaniso kwiipateni zesampulu zemisebenzi ebalulekileyo, hayi ukuphoswa kokugqibela.
Ukudityaniswa komthi we-wax bobunye ubugcisa obuzenza njengenkqubo. Ayikokuncamathelisa nje iinxalenye kwi-sprue. Uyilo lwesango-ii-angles, iindawo zokudibanisa, ii-diameters-zilawula ukuhamba kwesinyithi kunye nokuqina. Yifumane ingalunganga, kwaye ungenise isiphithiphithi okanye udale iindawo ezishushu ezikhokelela kwi-shrinkage porosity. Sifunde ukusebenzisa isoftware yokulinganisa hayi njengentonga, kodwa njengesiqalo sengxoxo. Isoftware inokucebisa uyilo, kodwa abafana bethu bomgangatho, abaneminyaka yeepatheni zokuqhekeka kwamehlo kwiigobolondo ezaphukileyo, bahlala behlengahlengisa ii-engile ngokusekelwe kwindlela i-slurry ikhupha ngayo ijometri yeqela elithile. Lolophu yempendulo yezandla ayinakubuyiselwa.
Kwaye ke kukho iwax ngokwayo. Ukubuyisela kwakhona kunye nokusetyenziswa kwakhona kwe-wax kusemgangathweni weendleko, kodwa ukuthotywa kwamakhonkco e-polymer emva kwemijikelezo emininzi itshintsha iipropati zayo. Iba brittle ngakumbi, ichaphazela ukugqitywa komphezulu. Kwindawo yethu, sibeka iliso kwisalathiso sokunyibilika kweebhetshi ezibuyiselweyo ngokwenkolo. Ukudibanisa intombi enyulu kunye newax ebuyiselweyo ukubetha ifestile yokusebenza ethile yinto yesiqhelo kodwa ngumsebenzi obalulekileyo. Yenye yezo nkcukacha zingathandekiyo ezahlula umgangatho ongaguqukiyo kwiziphumo ezigwenxa.
Isakhiwo seShell: Idabi loMaleko-ngoMaleko
Ukwakha iqokobhe leceramic kulapho inkqubo ifumana igama layo 'yotyalo-mali'. Utyala ixesha kunye nezinto eziphathekayo kwi-negative ebuthathaka ekufuneka imelane nokothuka kwe-thermal. Idyasi yokuqala yinto yonke. Lujongano olubamba iinkcukacha zomphezulu wepateni. Sisebenzisa i-slurry esekelwe kwi-zircon kwimisebenzi emininzi yentsimbi kunye ne-alloy-isakhiwo sayo esihle sengqolowa sinikeza ukugqitywa kwe-'as-cast' egudileyo. Kodwa i-viscosity kufuneka ihlolwe rhoqo, ilungiswe kwiqondo lokushisa. Ukutyeba kakhulu, kwaye ufumana ukwakheka kwengubo kwiimpawu ezintle; libhityile kakhulu, kwaye iqokobhe alinawo amandla aluhlaza.
Inkqubo ye-stuccoing ibonakala iqonde: ukudipha, ukukhupha, isanti. Kodwa ukhetho lwezinto ze-stucco kunye nobukhulu beenkozo kuluhlu ngalunye lucwangcisiweyo. Idyasi yokuqala inokufumana i-80-mesh yesanti ye-zircon ecocekileyo ukuphindaphinda iinkcukacha. Amaleko alandelayo anokusebenzisa imathiriyeli erhabaxa ye-alumina-silicate ukulungiselela ukudityaniswa komgangatho ophakathi kunye nokungeneka. Ndibone oonokrwece besilela kwi-autoclave ethotywayo ngenxa yokuba utshintsho phakathi kwamabanga e-stucco lwalukhawuleza kakhulu, ludala indawo yoxinzelelo. Yaqhekeka okweqanda. Ngoku, sineshedyuli yesituko esithweswe isidanga esibhaliweyo, kodwa igcisa elikhokelayo lisenengqiqo yokongeza idiphu ephakathi yedyasi ukuba iqokobhe elikwindawo enkulu yomthi likhangeleka likrokra.
Ukomisa phakathi kweedyasi lixesha lokwenyani-isinki. Ukuyingxamela ngowona mgibe uxhaphakileyo. Ukomisa okungonelanga kubamba ukufuma, okujika kube ngumphunga ngexesha le-dewaxing kunye nokuvuthela iqokobhe ngaphandle ngaphakathi. Siye safudukela kumagumbi okufuma alawulwayo, kodwa nalapho, umoya ojikeleza umthi oshinyeneyo awulingani. Sijikelezisa imithi phakathi kwemijikelo-isisombululo esisezantsi kwingxaki ephezulu. Akukho nto izenzekelayo ekwaziyo ukuphinda impompo eqheliweyo yeqokobhe ukumamela oko kumile okukroliweyo.
Ukukhutshwa kwewaxing kunye nokudubula: Inqaku lokungabuyi
I-Dewaxing kukuzalwa kobundlobongela kumngxuma wokungunda. Sisebenzisa i-autoclaves yomphunga woxinzelelo oluphezulu. Isitshixo sisantya-i-ramp uxinzelelo ngokukhawuleza ukunyibilikisa umphezulu we-wax ngoko nangoko kwaye wenze uxinzelelo oluqhumayo olutyhala ubuninzi be-wax ngaphandle kwe-sprue. Ukucotha kakhulu, kwaye i-wax iyanda ngokutshisa, iqhekeza igobolondo. Kodwa kukho ukulungelelana. Kwiipateni ezinkulu, eziqinileyo, ngamanye amaxesha sigrumba imingxuma yokunceda kwiindawo ezingabalulekanga ze-wax ukukhusela ukwakhiwa koxinzelelo. Luhlengahlengiso olungephi kwipatheni yewax egcina amawaka elahleko yeqokobhe.
Emva kokukhutshwa kwewax, ushiywe neqokobhe eliethe-ethe elizele luthuthu olushiyekileyo. Umjikelo wokudubula uyatshisa oku kwaye utshise i-ceramic ibe ngumbumba oqinileyo, we-monolithic. Umlinganiselo weqondo lobushushu ubalulekile. Ukukhawuleza kakhulu, kunye nokufuma okushiyekileyo okanye ukuguquguquka kunokubangela intlekele yokuqhekeka kweqokobhe. Sitshisa malunga ne-1000 ° C, kodwa ixesha lokubamba libaluleke njengobushushu obuphezulu. Imalunga nokufezekisa uguqulo olupheleleyo lwe-ceramic kunye nokulingana kwe-thermal. Iqokobhe elivulwe ngokufanelekileyo linesangqa esikhethekileyo kulo xa licofa kancinane—ukubetha okucothayo kuthetha ingxaki, ngokufuthi ukudinwa ngokwaneleyo, okuya kubangela iziphene zerhasi xa kuphosa.
Igobolondo elivuthayo lidluliselwa kwindawo yokuthulula. Ixesha eliphakathi kokutsalwa kwesithando somlilo kunye nokugalela isinyithi lugqatso. Vumela iqokobhe liphole kakhulu, kwaye usengozini yokubaleka kwenkungu okanye ukuvaleka okubandayo njengoko umphambili wentsimbi uqina ngaphambi kwexesha. Sijonge ukuthulula ngegobolondo phakathi kwe-800-1000 ° C, kuxhomekeke kwi-alloy. Oku kufuna ulungelelwaniso olukhohlakeleyo phakathi kwabasebenzi beziko lomlilo kunye neqela lotyalo-mali. Akukho ndawo yakulibazisa.
Ukugalela kunye nokuKnock-Out: Apho ithiyori idibana khona nomgangatho
Ukugalela kubonakala kuyamangalisa, kodwa ngeli nqaku, ininzi yekamva lokuphosa sele itywinwe. Injongo ephambili ngoku kukugcwalisa isikhunta ngokukhawuleza nangokucocekileyo. Sisebenzisa i-argon shielding kwi-alloys esebenzayo njenge-nickel-based ukukhusela i-oxidation. Inkqubo yokungena eyilwe kwiiveki ezidlulileyo ngexesha lokudibanisa i-wax ngoku ibonakalisa ukubaluleka kwayo. Ubukele isinyithi sinyuka kwikomityi yokugalela, ngethemba lokuba ihamba kakuhle, i-laminar ihamba ngaphandle kwe-vortexing enokuzoba kwi-slag.
Emva kokuqina kunye nokupholisa, lixesha lokunkqonkqoza. Lo ngumsebenzi we-cathartic kodwa unobungozi. Iqokobhe li-brittle kodwa linokubambelela ngokumangalisayo. Sisebenzisa oomatshini abangcangcazelayo kwaye ngamanye amaxesha iihamile ze-pneumatic kwii-castings ezinkulu. Injongo kukususa iqokobhe ngaphandle kokonakalisa ukuphosa okubuthathaka okanye ukubeka uxinzelelo olungafanelekanga kumacandelo amancinci. Kwiijometri zangaphakathi ezinzima, ukususwa kwe-ceramic core ngumngeni olandelayo. Ezinye izisombululo zothuthu lwesoda ziyasebenza, kodwa kwii-cores ezintsonkothileyo kwiindawo zentsimbi yealloyi, sihlala sibhenela kuxinzelelo oluphezulu lwejetting yamanzi okanye iindlela zomothuko ngononophelo lwe-thermal. Linqanaba elimdaka, elinomsebenzi omkhulu elikukhumbuza ukuba le asiyonkqubo yegumbi elicocekileyo.
Into osele nayo ngumthi orhabaxa, umthi, amasango, nazo zonke. Uhlolo lokuqala olubonakalayo lwenzeka apha. Iziphene ezigqwesileyo njengokushwabana okukhulu, iintanda, okanye ukuzaliswa okungaphelelanga ziyabonakala. Kodwa eyona miba ichuliweyo—imingxuma engaphezulu ephuma kwiqokobhe, ukugqwetheka okuncinci—ifuna iliso eliqeqeshiweyo. Sihlala sinqumle isampulu yokuphosa emthini ukusika-kunye-etch ngokukhawuleza ukujonga i-porosity engaphantsi komhlaba ngaphambi kokuzibophelela ekunqumleni ngokupheleleyo kunye nokugqiba.
UkuGqiba kunye neNxibelelaniso yeHlabathi yokwenyani
I-Cutoff, ngokuqhelekileyo ngamavili abrasive okanye i-saw band, sisiqalo sokugqiba. Emva koko kuza ukugaya ukususa iziqu zesango. Apha kulapho ukunyamezelana komlinganiselo ekugqibeleni kuqondwa—okanye akunjalo. Inkqubo eyilwe kakuhle ishiya isitokhwe esincinci sokucoca. Sijonge kwimilo ekufutshane ne-net-shape, kodwa umda wokhuseleko we-0.5-1mm ngumgangatho wemilinganiselo emininzi ukuze i-akhawunti yeshifti encinci yokuphosa. Kwinkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye nokuhlanganiswa kwayo CNC Machining amandla, eli likhonkco elibalulekileyo. Ukusasa kuyilwe kucingwa ngee-machining datums. Icala le-Foundry livelisa i-casting engeyiyo nje isandi sejometri, kodwa iphinde ibe nesitokhwe sodonga esingaguqukiyo ukwenzela ukuba oomatshini basebenze. Kuluhlanganiso oluthe nkqo ukusuka iqokobhe ngundo ukuphosa kwaye utyalo mali kumatshini ochanekileyo osivumela ukuba siphathe izinto ezivela kwi-ductile intsimbi ukuya kumaphupha amabi ukuya kumatshini ialloys esekwe cobalt kwaye uhambise icandelo eligqityiweyo.
Ukuhlolwa kokugqibela kulapho lonke ulawulo lwenkqubo luhlawula khona. Iitshekhi ezinobungakanani, uvavanyo lwedayi yokungena kwiziphene zomhlaba, iX-reyi yokuthembeka kwangaphakathi. Kwizinto ezicacileyo eziphezulu kwii-alloys ezikhethekileyo, siya kwenza isiqinisekiso semathiriyeli epheleleyo, silanda inani lobushushu le-ingot emva kwayo yonke inkqubo. Iphelele, kodwa kuphela kwendlela yokuqinisekisa ukusebenza kwizicelo ezibalulekileyo.
Ukujonga emva, ukulahlwa kotyalo-mali olulahlekileyo lutsheyini lweenkqubo ezincinci ezilikhulu. Amandla ekhonkco akukho nakweliphi na ikhonkco eligqibeleleyo, kodwa ekuqondeni ukuba ikhonkco ngalinye lichaphazela njani elilandelayo. Imalunga nokuqikelela ukuba utshintsho kuxinzelelo lwenaliti ye-wax inokuchaphazela ixesha lokumisa iqokobhe lecandelo elishinyeneyo, okanye indlela yokukhetha intsimbi engenasici ibakala lichaphazela iqokobhe preheat lobushushu efunekayo ukuze kugcwaliswe ecocekileyo. Lusiko olupheleleyo, ngamanye amaxesha olunengqiqo olwakhelwe kwisiseko sezinto eziguquguqukayo ezilawulwayo kunye namava aphumelele nzima. Yiloo nto iminyaka engamashumi amathathu kweli shishini, ngathi QSY, eneneni kuthetha—kungekhona nje ukwenza izinyuko, kodwa ukwazi ubunzulu, unxibelelwano oludla ngokungathethwa phakathi kwabo. Unokufumana ukujonga okunzulu kwindlela yabo yokuphosa okudibeneyo kunye nomatshini kwindawo yabo, https://www.tsingtaocnc.com, ebonisa le filosofi isebenzayo, isiphelo ukuya ekupheleni.
