Lapho onjiniyela basemkhathini bedinga ama-turbine blades, ama-nozzles kaphethiloli, noma izindlu ze-actuator ezibamba ukubekezelela okungu-±0.02 mm ngaphansi kokuhamba ngebhayisikili okushisayo okungu-800°C kanye nemithwalo engu-15,000 ye-psi hydraulic—abakufanelanga ukusakaza “okwanele”. Baya ku-an imboni yokusakaza utshalomali lwe-aerospace ngesiyalo esiqinisekisiwe se-metallurgical, hhayi nje ikhono lokwenza isikhunta.
Yingakho amaqembu abaklami eNyakatho Melika naseYurophu ehlala ethumela imidwebo ecebile ye-GD&T yezingxenye zephampu ye-cobalt-nickel ngokuqondile ku-Qingdao Qiangsenyuan Technology Co., Ltd.—hhayi ngoba iyinketho eshibhe kakhulu, kodwa ngenxa yokuthi uchungechunge lwezinqubo lwayo luqeda amaphuzu okuhluleka avame kakhulu: ukushwabana okuncane ezingxenyeni ezinezindonga ezincane, ukuhlukaniswa kwe-carbide, ukuhlukaniswa kwe-carbide cast kanye nokuhlukaniswa kokushisa kwe-carbide 53m7 diensional MS kanye nokwenza imishini yokugcina.
Abekho abalingisi ababili basemoyeni abaziphatha ngendlela efanayo—kanjalo nefekthri akufanele
Sibone amaphrojekthi amaningi abambezeleka ngenxa yokulindela okungafani: umphakeli ecaphuna "ukufakwa kwe-investimenti" ngenkathi esebenzisa i-sand-cast tooling; enye eqinisekisa "i-AMS 5387 ethobelanayo" ngaphandle kwemibiko ye-spectrographic eqondene neqoqo; owesithathu ophethe idatha ye-CMM kuphela yokuhlolwa kwesihloko sokuqala—hhayi yonke indawo. E-Qingdao Qiangsenyuan, impendulo iqala ngokulandeleka kwezinto ezibonakalayo—hhayi izimangalo zokumaketha.
Yonke ingot ye-alloy esekelwe ku-T800 ifika nemibiko yokuhlolwa komshini wokugaya, ukuhlaziywa kabusha kwamakhemikhali esizeni, kanye namalogi omlando oshisayo aboshwe ekushiseni ngakunye. Lokho kusho ukuthi lapho ikhasimende li-oda imibhobho ye-cobalt alloy engu-42 yesistimu yokulinganisa uphethiloli yomfutho ophezulu, i-Foundry ayitheli nje insimbi—ibonisa ukuma okusanhlamvu ngokumelene nesiqondiso sokugeleza ekuhlanganiseni kwephethini ye-wax, ilungisa izinga lokushisa lokushisa ngaphambi kobukhulu besigaba ngasinye, futhi ibamba isikhathi sokuqina phakathi kwamasekhondi angu-±90 wokuphuma kokulingisa.
Lokhu akulona ithiyori. Kwenye iphrojekthi yakamuva ye-OEM ye-hydraulic hydraulic actuator, sibambe ukuchezuka kokuqina kodonga okungu-0.035 mm ku-wax master *ngaphambi* kokucwiliswa kwegobolondo le-ceramic—sisebenzisa i-optical contour scanning esikhundleni sama-caliper manual. Lokho kusindisa amasonto amathathu okusebenza kabusha futhi kwasusa izinsalela ekulingiseni kokuqala okungu-17.
Ukuhlanganiswa okuqondile akuyona i-buzzword—ukuphela kwendlela yokulawula ubuqotho besakhiwo esincane
Abahlinzeki abaningi bakhipha izinsiza zokuqedela, ukwelashwa kokushisa, noma ukukhanda imishini kokugcina. Lokho kwephula ukuziphendulela-futhi kwethula okuguquguqukayo okungalawuleki. Umsebenzisi wesithando sokushisa ukushisa endaweni eyodwa angase agibele ku-5°C/min; enye ku-12°C/min. Zombili zihlangana ne-“AMS 2750E Class 2” ephepheni—kodwa eyodwa kuphela eletha ukuhlakazeka okungaguquguquki kwe-cobalt-nickel alloys.
I-Qingdao Qiangsenyuan iqhuba zonke izinyathelo ezibucayi ngaphansi kophahla olulodwa oluthobela i-ISO: ukufakwa kwe-investimenti, ukwenziwa kwemishini ye-CNC ye-axis eminingi (okuhlanganisa i-contouring ye-axis engu-5 ngesikhathi esisodwa), ukwelashwa kokushisa kwe-vacuum, kanye nokuqedwa kwendawo efana ne-electropolishing noma i-HVOF coating. Awekho ama-handoffs. Azikho izikhala zedatha. Cha "ushilo/ushilo" ngesikhathi sokuhlaziya imbangela yezimpande.
Waba yini umphumela? Izindlu zesilinda sephampu ye-Piston ezidlula ukuhlolwa kwengcindezi engu-100% ku-1.5× ingcindezi yokusebenza—ngokuvuza okunguziro kumayunithi angama-212 ekugijimeni kwevolumu emaphakathi yakamuva. Kungani? Ngoba ithimba elifanayo eliqinisekise idizayini yesango liphinde laqinisekisa ubulukhuni bokugcina bendawo ye-ID (Ra ≤ 0.4 µm) nokusabalalisa kokuqina okuqinisekisiwe (HRC 42–46) kubo bonke ubude bobhore—hhayi nje kumasampula amathathu amaphuzu.
Akukhona mayelana nokuphonsa izingxenye-kumayelana nokusebenza okufanelekile okusebenzayo
Amanye amafekthri e-aerospace casting investments aphatha i-GD&T njengomhlobiso. I-Qingdao Qiangsenyuan iyithatha njengenkontileka. Uma umdwebo udinga ukubekezelela indawo okungu-Ø0.05 mm ezimbobeni zamabhawodi ayisithupha uma kuqhathaniswa nendiza yedatha emshinini ngemva kokusakazwa, indawo yesitolo isebenzisa umshini wokulinganisa ohlanganisayo onokucaca okungu-0.001 mm—futhi irekhoda konke ukufundwa kusizindalwazi esivikelekile esixhunywe nenombolo yokushisa yengxenye.
Lelo zinga lokuqina libaluleke kakhulu lapho ijiyomethri ihlangana khona nomsebenzi: amarola e-winch center shaft ezimoto zobunjiniyela kufanele azungezise ngokweqiniso ngaphakathi kuka-0.01 mm inani eliphelele lokufunda ngenkomba (TIR) ngaphansi komthwalo oguquguqukayo. Amavalvu okucindezela adinga izindawo zokuvala ezingavuzi ezinomkhawulo ohambisana nephrofayili yesethi yokuminyanisa ye-elastomer. Lokhu akuzona "izinto ezinhle zokuthola." Ziyinqubo yokudlula/yokwehluleka eshumekwe kuyo yonke iphrothokholi yokuhlola.
Amakhasimende asitshela ukuthi lokhu kwenza ukubuyekezwa konjiniyela kusheshe—hhayi ukunensa. Umkhiqizi wephampu waseNyakatho Melika unqamule umjikelezo wokuphindaphinda komklamo wakhe usuka ezinsukwini eziyi-11 uye ezinsukwini ezi-3.5 ngemuva kokushintshela empendulweni yokuqala yokwenziwa ye-Qingdao Qiangsenyuan: ukuhunyushwa kwesikhathi sangempela kwe-GD&T, ukumodeliswa kwezitaki zokubekezelela, nezinye iziphakamiso zezinto ezisekelwe kumajika angempela okuphendula okwelapha ukushisa kwangaphakathi—hhayi amadatha edatha ajwayelekile.
Ukubheka phambili: izinqubo ezihlanganisiwe, hhayi nje ukusakaza
Umngcele olandelayo awuwona amafusi amakhulu noma ama-CMM asheshayo. Kuqina ukuhlangana phakathi kokulingisa nokwenza imishini—ikakhulukazi kumajiyomethri angaphakathi ayinkimbinkimbi okungenakwenzeka ukuba afezeke nganoma iyiphi inqubo yodwa. Manje sithuthukisa ukugeleza komsebenzi okuxubile lapho ukwakheka kwe-investimenti eseduze nenetha kwenzeka ngokunemba kokumba kwe-EDM *ngaphambi* kokugaya kwe-CNC kokugcina—okunika amandla amashaneli okupholisa ngaphakathi kwezindlu eziphehla umoya ezinobugqinsi obungu-0.3 mm nobukhulu obungu-12:1.
Lokho kudinga ukubambisana okujulile kwe-R&D—hhayi nje namakhasimende, kodwa nozakwethu besayensi yezinto ezibonakalayo. Njengamanje, umsebenzi wethu wokuthuthukisa ohlanganyelwe ugxile ekwandiseni izindlela zokuqinisa izinhlobo ze-T800 zesigaba esiphansi se-sigma-sigma, ukwehlisa isikhathi sokuvala isixazululo se-post-cast ngo-37% ngaphandle kokuphazamisa ukumelana ne-creep.
Uma ingxenye yakho elandelayo ye-aerospace idinga okungaphezu kokunemba kobukhulu—uma idinga ukuziphatha okubikezelwe kwensimbi, ukulandeleka okugcwele, kanye nokungabekezeleli lutho ekukhukhuleni kwenqubo—udinga imboni yokusakaza utshalomali lwe-aerospace yakhelwe ukwenza umsebenzi obalulekile. Hhayi ivolumu. Hhayi isivinini. Isiqiniseko.
