Xa iinjineli zicacisa iinxalenye zeenkqubo ze-hydraulic, iimpompo ze-oilfield, okanye ii-winch-duty-winch assemblies, "i-precision metal casting factory" ayikho nje igama lokukhangela-yinto engenakuxoxisana. Uzinzo lwe-Dimensional phantsi kwe-500-bar yoxinzelelo. Ukunyaniseka kweMicrostructure emva kokuhamba ngebhayisikile yobushushu. Isiphelo somphezulu esixhathisa ukhukuliseko oluludaka oluludaka. Ezi ayizonyamezelo-ziimeko zokuphila. Kwaye bafuna ngaphezu kwezixhobo zokujula; zifuna uqeqesho metallurgical, ukuqhubeka inkqubo, kunye nobunjineli ukuphendula inyathelo ngalinye.
Kutheni le nto iCobalt Alloys ifuna ngaphezulu kuneendlela zokuCasa eziMgangatho
Siye sabona iiprojekthi ezininzi kakhulu xa umthengisi ephatha i-AMS 5387 cobalt alloy njengentsimbi esemgangathweni engama-316. Isiphumo? Iintanda kwizindlu zempompo emva kweeyure ezingama-400 zokusebenza. Iirola zeshaft eziseziko elijijekileyo kwiiwintshi zemoto yobunjineli. Amaxabiso obunzima obungenakuphinda buveliswe kuzo zonke iibhetshi-nangona kuseto lweziko ezifanayo. Ngoba? Ngenxa yokuba i-cobalt-nickel superalloys ayixhathisi nje ukunxiba-iyaxhathisa ukuqikelelwa. I-conductivity yabo ye-thermal isiqingatha sentsimbi. Ukuncipha kokuqina kwabo kuyaguquguquka. Ubuchwephesha babo behla nge-70% emva kokufakwa kwesisombululo.
Kungenxa yoko le nto iifektri ezichanekileyo zokuphosa isinyithi zityala imali ekulandeleleni izinto ezivaliweyo-hayi nje amanani ebhetshi, kodwa iilogi zembali yobushushu ezigcweleyo zibotshelelwe kwisakhelo ngasinye. Zifaneleka kwangaphambili izibophelelo zesanti ze-T800-grade alloys, hayi isilica yegeneric. Baqinisekisa imijikelo yokutshiswa kweqokobhe lotyalo-mali ngemephu ye-thermocouple-hayi ingqikelelo esekwe kwixesha. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke i-cobalt nozzle okanye iplagi iqala ngemathiriyeli ekrwada eqinisekisiweyo evela kubaxhasi be-Tier-1-kwaye iphetha ngengxelo ye-CMM ebonisa ukutenxa kwe-± 0.015 mm kwiindawo ezibaluleke kakhulu zokutywinwa, kuqinisekiswe ngaphambi kokuba kuqale ukusebenza.
Ukudityaniswa okuthe nkqo akusiyo i-Buzzword-Yiyo kuphela indlela yokubamba i-GD&T
Abanye abathengisi bakhuphela ngaphandle, emva koko bathenge umthamo we-CNC kwiimarike zendawo. Oko kudala iindawo ezintathu zokungaphumeleli: ukukhukuliseka okuphakathi phakathi kwelizwe kunye noomatshini, iifestile zonyango lobushushu ezingahambelaniyo, kunye nolawulo lweqanda phezu kwemfezeko yomphezulu ngaphambi kokugqiba. Sijonge amakhulukhulu eendawo ezikhatywayo apho ukuphosa kwadibana khona-kodwa umphezulu we-as-cast une-micro-porosity eye yavela kuphela emva kokusila kokugqibela.
Ukudityaniswa kokwenyani kuthetha ukulawula lonke ikhonkco: utyalo-mali → ukuthomalalisa uxinzelelo → umatshini we-multi-axis → unyango lobushushu lwasemva komatshini → ukugqitywa komphezulu ochanekileyo. Kwizindlu zepiston pump cylinder, oko kuthetha ukubamba ubungqukuva ngaphakathi kwe-0.008 mm ngaphaya kwe-300 mm ubude—nasemva kwe-nitriding. Kwiivalvu zoxinzelelo, kuthetha ukugcina ubunzulu phakathi kwesihlalo kunye neflange enyukayo yangaphandle ngaphakathi kwe-0.02 mm-kuzo zombini imizimba yentsimbi ephoswe esantini kunye nezixhobo zomatshini ze-cobalt trim. Oku akunakwenzeka ngaphandle kwedatha yezixhobo ekwabelwana ngazo, ukucwangciswa okudityanisiweyo, kunye neqela elinye elisemgangathweni elisayinayo kwindawo nganye yotshintsho.
Kuthetha ukuthini “Ukuchaneka” ngokwenyani kwi-Industrial Casting (Ngaphaya kweMicrons)
Buza iinjineli ezilishumi ukuba kuthetha ukuthini "ukunyamezela okuphezulu", kwaye uya kufumana iimpendulo ezilishumi elinanye. Kodwa kwizicelo zehlabathi zokwenyani, izitaki zonyamezelo azihlali zodwa. Izindlu ezimalunga ne-±0.02 mm zibalulekile kuphela ukuba uburhabaxa bomphezulu beshafti yokukhwela buhlala ngaphantsi kwe-Ra 0.4 µm—kwaye ukuba i-coefficient yokwandiswa kwe-thermal yazo zombini imathiriyeli ilungelelaniswa ngaphakathi kwe-10% ukunqumla -20°C ukuya +120°C.
Kungenxa yoko le nto iifektri ezichanekileyo zokuphosa isinyithi kufuneka zibethelele ukuqinisekiswa okusebenzayo-kungekhona nje ukujonga umyinge. Yonke ivalve yoxinzelelo ifumana uvavanyo lwe-hydrostatic kwi-1.5 × uxinzelelo lokusebenza. Yonke i-winch center shaft roller iqhuba ukuqinisekiswa kwebhalansi eguqukayo kwi-3,500 RPM. Yonke i-cobalt alloy nozzle idlula uhlolo lwedayi *kunye* ne-ultrasonic scanning ye-subsurface dendritic segregation. Ezi ayizongezo. Zakhelwe kwimiyalelo yomsebenzi-kunye nemilinganiselo yokupasa / yokungaphumeleli ebhaliweyo, enokuphicothwa, kwaye igcinwe iminyaka eyi-10.

Ukukhetha Iqabane—kungekhona Umthengisi Kuphela
Isiliphu semihla yokuhanjiswa. Imizobo iyaguquguquka. Izixhobo ziyatshintshwa. Into eyahlula umzi-mveliso wesinyithi othembekileyo ochanekileyo yindlela ezisingathwa ngayo ezo ziganeko—kungekhona nokuba ziyenzeka. Sijonge abathengi bephulukana neenyanga xa umthengisi esala ukutolikwa kwe-GD&T ngexesha lokuphononongwa koyilo, enyanzelisa ukuba "thumela nje umzobo." Abanye balibazise iiprototypes kwiiveki ezintandathu ngenxa yokuba i-Foundry ayinakho ukukwazi ukuqinisekisa ubukhulu bodonga kwipatheni yotyalo-mali eprintiweyo ye-3D.
Iqabane elifanelekileyo liqala ngempendulo yokwenziwa-kungekhona emva kokucaphula, kodwa ngexesha lophononongo lobunjineli. Benza iflegi yee-engile zokuyila ezibangela ukuqhekeka kweqokobhe kwi-cobalt alloys. Bacebisa iindlela ezizezinye zokugawula ukunciphisa i-porosity kwiziseko zempompo ezinodonga olucekethekileyo. Baqinisekisa izatifikethi zezinto ezihambelana nendawo yakho yokuphela kokusetyenziswa-nokuba yinkonzo yerhasi emuncu (NACE MR0175) okanye ukumelana nokugqwala kolwandle (ISO 12944 C5-M).
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngale ndlela-kungekhona njengomgaqo-nkqubo, kodwa njengesiqhelo semihla ngemihla. Indawo yayo ehambelana ne-ISO iphatha yonke into ukusuka kwiprototypes enye ukuya kwimveliso yevolumu ephakathi, kunye nesicwangciso esicwangcisiweyo esilandelela izixhobo zebhotile ngexesha langempela. Akukho "intlawulo ezikhawulezayo." Ayimangalisi intlawulo ye-NRE. Iinkqubo ezibhalwe nje, iziphumo ezinokulandeleka, kunye nencoko yobunjineli eqala ngokuthi "Iza kusilela njani le nxalenye?" - hayi "Lithini ixabiso?"
Ukuba umsebenzi wakho olandelayo ubandakanya iivalvu ezinoxinzelelo oluphezulu, izindlu zempompo, okanye iishafti ezigugayo, qalisa ngombuzo othi: Ngaba umzi-mveliso wakho owenziwe ngesinyithi ochanekileyo ulinganisa impumelelo kwiimicrons—okanye phakathi kwexesha elithile phakathi kokusilela? Impendulo imisela ukuba icandelo lakho lihlala iiyure ezingama-500-okanye ama-5,000.
