Xa usiva 'inxalenye ye-nickel-based alloy mechanical,' ingcamango engoko nangoko idla ngokusebenza ngokugqithiseleyo—iinjini zejethi, iiinjini zomoya, ukusetyenziswa kakuhle kokugqibela. Ayonto iphosakeleyo, kodwa kukuqonda okungaphezulu okunokuthi kukhokhelele kwiindleko ezigwenxa kwiinkcukacha kunye nokuthengwa kwempahla. Ibali lokwenyani lisekusila, ukuxoxa ngomatshini, ukulwa ngexesha lonyango lobushushu, kunye nempumelelo ezolileyo yenxalenye engasileliyo phantsi koxinzelelo. Emva kokuba ndifumene kwaye ndibeke iliso kwimveliso yamacandelo kumacandelo afunayo, ndiwubonile umsantsa phakathi kwezithembiso zedatha yedatha kunye nenyani yomgangatho wevenkile. Akunjalo nje ngokukhetha i-Inconel 718 okanye i-Hastelloy C-276 kwikhathalogu; malunga nokuqonda ukuba loo nto iya kuziphatha njani ukusuka kwintsimbi etyhidiweyo ukuya ekugqibeleni, icandelo elisebenzayo.
I-alloy ayiyondawo yokuQala; Indlela Yokusilela Yiyo
Iiprojekthi ezininzi kakhulu ziqala nge-nickel alloy part. Oko kusemva. Incoko kufuneka iqale ngoxinzelelo oluthile: ngaba kukudinwa kwe-cyclic thermal, ukubonakaliswa kwe-chloride rhoqo, okanye indibaniselwano yokhukuliseko kunye nobushushu obuphakathi? Umzekelo, ukucacisa i-Inconel 625 ngokuxhathisa kwayo kokutya xa isoyikiso esiphambili sisisulufu kuluhlu oluthile lobushushu yinkcitho eyinkunzi. Ndikhumbula icandelo levalvu yokusetyenzwa kweekhemikhali apho i-spec yokuqala yayiyeye-generic high-nickel alloy. Emva kokuhlalutya umsinga wenkqubo, siye satshintshela kwichromium ephezulu, ukwahluka kwentsimbi esezantsi, enika ukuxhathisa okungcono kwindawo ethile eneasidi ngaphandle kweprimiyamu yeendleko ezingeyomfuneko zebakala elingaqhelekanga. I-alloy sisixhobo, kungekhona indebe.
Kulapho ukusebenzisana ne-Foundry kunye nevenkile yomatshini efumana lo mahluko kubaluleke kakhulu. Ufuna umthengisi obuza ukuba kutheni phambi kokuba bangaphi. Ivenkile efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye namashumi amathathu eminyaka abo ekujuleni nasekusebenzeni, ngokwesiqhelo banaloo ngcinga yendeleyo. Bayibonile imiphumo yokusetyenziswa kakubi kwenzululwazi yezinto. Amava abo ngaphaya iqokobhe ngundo ukuphosa, utyalo mali, kunye nokugqiba nge CNC Machining kuthetha ukuba bajonga inxalenye ngokupheleleyo, hayi njengamanyathelo okusebenza awodwa. Unokufumana indlela yabo eneenkcukacha kwiqonga labo https://www.tsingtaocnc.com. Ngulo mbono odibeneyo othintela iintlekele.
I-nuance ikwiinkcukacha abanokuthi baphawule. Kwi-impeller yempompo, banokubuza uyilo oluqinileyo, becebisa umngxuma ongenanto, utyalo-mali-isakhiwo sokunciphisa ubunzima be-centrifugal kunye noxinzelelo, nokuba lunzima ukwenza iipateni zabo. Okanye banokucebisa ngokuchasene nesixhobo sokusika esinobunkunkqele esinenqaku elinye kwi-alloy eqinisiweyo yobudala, becebisa ulandelelwano olwahlukileyo lokulawula ukuqina komsebenzi kunye noxinzelelo olushiyekileyo. Le asiyonkonzo nje; yintsebenziswano yobunjineli.
Ukuphosa: Apho i-Microstructure Destiny itywinwe kakhulu
Awungekhe umatshini kwiipropathi ezilungileyo ukuba ukuphosa kunesiphene. Kuba ialloys esekwe nickel, ukuziphatha kokuqinisa yinto yonke. Bathanda ulwahlulo, ukukrazuka okushushu, kunye ne-porosity ukuba i-gating kunye nenkqubo yokunyuka ayilwanga ngobunono. Ndikhe ndabona utyalo-mali oluhle, olugqibeleleyo oluye lwasilela kuhlolo lweX-reyi ngenxa yokuba i-thermal gradients ibingalawulwa. I-alloy imile ngokungalunganga, idala i-micro-channels yobuthathaka.
Ukwenziwa kobunjwa beqokobhe kwivenkile efana ne-QSY ibonelela ngozinzo olufanelekileyo lwe-dimensional yeejiyometri ezilula, kodwa kwiipaseji ezintsonkothileyo zangaphakathi zeblade ye-injini okanye umzimba wesitofu se-fuel, utyalo mali ayixoxisi. Iqokobhe leceramic livumela olo bunzima. Kodwa nanku umgibe: ukucinga ukuba umphezulu wokugqiba kutyalo-mali ulungele inkonzo yokudinwa komjikelo ophezulu. Ngokuqhelekileyo akunjalo. Umphezulu we-as-cast unokugcina iinotshi ezibonakala zincinci zibe ziindawo zokuqalisa ii-crack. Ukukhanya, ukuqhuma kwegrit elawulwayo okanye inyathelo le-electropolish-ebonakala ngathi incinci-inokuba ngumahluko phakathi komjikelo we-10,000 kunye nobomi bomjikelezo we-100,000. Olu luhlobo lwenkqubo ye-nuance umqhubi wexesha elide ayakha kwindlela yokusebenza esemgangathweni.
Ukungaguquguquki kwezinto lelinye ibala lokulwa. I-alloy esekwe kwi-nickel lusapho. Ngaba ufumana ukunyibilika okucocekileyo, okunyulu kunye nolawulo oluluqilima lokulandelela umkhondo, okanye ngaba kukho ipesenti yokubuyisela imathiriyeli edityanisiweyo? Kuninzi lwezicelo ezingezizo ezomoya, ukubuyisela okunye kunoqoqosho kwaye kwamkelekile, kodwa ipesenti ibalulekile. Ulawulo lwe-Foundry phezu kwekhemistri yayo yokunyibilika kunye nomkhondo wayo wamaxwebhu yeyona nto ibalulekileyo. Ngumbuzo omawubuze.
I-Machining Gauntlet: Ukuhlonipha intando yeMathiriyeli yokulwa
Apha kulapho ithiyori idibana khona ngokubambekayo. Iialloys ze-nickel zidumileyo kwaye zisebenza nzima ngokukhawuleza. Ukusikwa okuthandabuzayo okanye isixhobo esibuthuntu kancinane asivelisi nje ukuphela okubi; idala ulusu oluqinileyo olwenza ukudlula okulandelayo kube nzima ngakumbi, okunokonakalisa inxalenye kunye nesixhobo. Isipholisi asenzelwa ukupholisa nje; yeyokuthambisa kwincam yokusika ukuthintela ukuncamathela kwezinto. Sifunde oku kabuhlungu kwangethuba ngebhetshi ye-Inconel 718 izibiyeli. Umchwephesha, owayesebenzisa i-stainless, wasebenzisa ukutya okufanayo kunye nezantya. Umphumo waba zizixhobo ezitshisiweyo, iindawo ezigqwethekileyo ngenxa yobushushu, kunye nebhetshi echithiweyo. Isifundo esixabisa kakhulu.
Iphumelele CNC Machining Ezi ndawo zifuna izixhobo zoomatshini eziqinileyo, izixhobo ezikhethekileyo zejiyometri (iharika entle, imiphetho ebukhali), kwaye rhoqo, ukupholisa koxinzelelo oluphezulu oluqondiswe ngokuchanekileyo. Yinkqubo ecothayo, eyenziwe ngabom. Ivenkile efana ne-QSY, ephethe i-machining endlini emva kokuphosa, inenzuzo. Bayayazi i-microstructure ethile kunye nemeko yoxinzelelo olushiyekileyo lwezabo zokuphonswa, ukuze bakwazi ukwenza ulandelelwano lomatshini ngokufanelekileyo. Abalwi into engaziwayo ukusuka kumntu wesithathu ongenanto.
Ukukhululeka koxinzelelo lwasemva komatshini lelinye inyathelo elibalulekileyo, elihlala lingahoywa. Inkqubo yomatshini inika uxinzelelo. Kwinxalenye ejongene nebhayisekile eshushu, lityala. Umjikelo wokunciphisa uxinzelelo lobushushu obuphantsi, ngelixa ukongeza ixesha kunye neendleko, uzinzisa inxalenye. Ngomnye waloo manyathelo angabonakaliyo ahlula inxalenye esebenzayo ukusuka ethembekileyo.
Imeko kwindawo: I-Bracket ephantse yayingekho
Umzekelo wekhonkrithi: isibiyeli esixhomayo senzwa yobushushu obuphezulu kwi-oven yoshishino. I-specke ibize ukuxhathisa kwe-oxidation ukuya kuma-980 ° C kunye namandla alungileyo okurhubuluza. Uyilo lokuqala yayiyimveliso edityanisiweyo evela kwisitokhwe sebha eqengqelekayo. Iprototype ayiphumelelanga kwi-welds ngexesha lokuhamba ngebhayisikile ye-thermal-indawo echaphazelekayo yokushisa yaba yikhonkco ebuthathaka.
Uhlengahlengiso lutshintshelwe kwi-monolithic, i-investment-cast part kusetyenziswa i-nickel-chromium alloy elungiselelwe ukumelana ne-oxidation. Ubunzima babuphantsi, ngoko ke ukubunjwa kweqokobhe kwakuqwalaselwa. Nangona kunjalo, ukufezekisa iimbambo zokuqinisa zangaphakathi eziyimfuneko kunye nokuphepha ukugxininiswa koxinzelelo olusuka kwiikona ezibukhali, uyilo lufuna iifayili ezigudileyo kuphela ezinokufezekiswa ngokutyalo-mali. Sasebenza neqela lobunjineli e QSY kuyilo lwepateni ukuqinisekisa ukuba ubukhulu bodonga kunye nokungena okufanelekileyo. Inxalenye yaphoswa, emva koko ichaneka-omatshini kuphela kwindawo yokunyuka.
Undoqo yayiyindlela edibeneyo. Ngenxa yokuba iqela elifanayo lijongene nokuphosa kunye nomatshini, banokuyila ukuphosa ngesitokhwe esongezelelweyo (isibonelelo) kwiindawo ezifanelekileyo zokusebenza kwe-CNC yokugqibela, ukunciphisa ixesha lomatshini kunye nokugcina imfezeko yezinto eziphathekayo. Inxalenye yaya enkonzweni kwaye yenza ngaphandle kwengxaki. Impumelelo yayingekho kukhetho lwealloyi kuphela; yayikwisandla esingenamthungo ukusuka kukungunda ukuya kumatshini.
Ukujonga Ngaphaya kwePhepha leDatha: IFactor yoLuntu
Okokugqibela, eyona nxalenye ibalulekileyo kwitsheyini ayiyontsimbi; bubuchule. Unokuba nazo zonke iziqinisekiso ze-ASTM emhlabeni, kodwa ukuba iqela lomgangatho wevenkile alinayo i-intestined, phantse i-intuitive ivakalelwa ngendlela i-nickel alloy eziphatha ngayo xa inqunyulwa okanye iqokobhe le-ceramic kufuneka likhutshwe, ukuhambelana kukungcakaza. Eli lixabiso elingaphathekiyo lomboneleli onembali yokusebenza kwexesha elide. Benze iimpazamo, basombulula iipuzzle, kwaye baphuhlisa iindlela zobunini ezingazange zifikelele kwincwadana yokuthengisa.
Xa uvavanya umthombo, buza malunga neeprojekthi zabo zembali. Buza malunga nexesha iprojekthi engaphumelelanga kunye nendlela abayifumanisa ngayo. Impendulo yabo iya kukuxelela ngaphezu kwalo naliphi na iphepha lesakhono esimenyezelayo. Iwebhusayithi ye Qingdao Qiangsenyuan Technology Co., Ltd. ikhankanya iminyaka engama-30 yokuba sesikhundleni kunye nokusebenza nayo ialloys ezikhethekileyo. Elo xesha lithetha ubunzulu bolwazi lweziko lokusonjululwa kwengxaki olungenakuphinda luthathelwe indawo ukuze kujongwe ubunzima iindawo ze-nickel-based alloy mechanical.
Ekugqibeleni, ukufumana la malungu ngumsebenzi kumngcipheko olawulwayo. Ulinganisa ukusebenza, iindleko, kunye nexesha lokukhokela. I-alloy ikunika amandla, kodwa bubuchule bokwenza kunye nokwenza-uhlobo olwakhiwe kumashumi eminyaka-oluvula loo mandla ngokuthembekileyo. Musa ukuthenga nje into ethile; thenga inkqubo, kwaye uthenge amava emva kwayo.
