Xa iinjineli zichaza a Umzi-mveliso wokugalela imali ngokwesiko, abagcini nje uku-odola iinxalenye-bazinikela ekuzinzeni kwe-dimensional, ingqibelelo ye-microstructural, kunye nokuthembeka kokusebenza phantsi kweemeko ezinzima. Siye sabona iiprojekthi ezininzi kakhulu zilibazisekile ngenxa yokungahambelani kobuchule besiseko: ipompo yendlu ephoswe nge-porosity kufutshane nomphezulu wokutywina; i-cobalt alloy nozzle eyenziwe nge-subsurface microcracks emva kokunyanga ubushushu; i-winch centre shaft roller ephumelele ukuhlolwa kweCMM kodwa yasilela uvavanyo lokudinwa kwi-42% yobomi bokuyila. Ezi ayizizo iimeko-ziimpawu zokuqhekeka kwamatyathanga kunye nabathengisi begeneric abasweleyo inkqubo ye-alloy-specific.
Kutheni i-Material-Specific Casting Yazi-iNjani iBetha “Ubungakanani obunye-Ilingana-Konke” Abaseki
Utyalo-mali alukho malunga nokugalela isinyithi esinyibilikisiweyo kumaqokobhe eceramic. Kumalunga nokulawula i-gradients zokuqinisa kwi-AMS 5387 cobalt alloy-apho i-0.3 ° C / min izinga lokupholisa izinga lokuphambuka liguqula isithuba se-dendrite yengalo kunye nokunciphisa ukuxhathisa ukhukuliseko kwiindlela ze-high-speed fluid. Kumalunga nokulawula ukungahambelani kokwandiswa kwe-thermal phakathi kwee-cores ezisekelwe kwi-T800 kunye namaqokobhe ensimbi engenasici ngexesha lokuthotywa, ukuthintela i-microfissures engabonakaliyo kwi-X-ray kodwa yintlekele phantsi koxinzelelo lwe-cyclic. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke i-cobalt-nickel egalelwe iqala ngokubumba kwangaphambili okufudunyezwe kwi-1,120 ° C ± 5 ° C-kungekhona uluhlu, kodwa kujoliswe kuyo kuqinisekiswe ngeepyrometers ze-infrared ze-infrared phambi kwebhetshi nganye. Asiyiphathi i-AMS 5387 “njengenye nje enye i-superlloy.” Siyiphatha njengezinto ezifuna ii-crucibles ezizinikeleyo, ukuhlanjululwa kwe-argon ye-oksijini, kunye nesisombululo se-post-cast annealing kwiziko le-vacuum kunye ne-± 2 ° C efanayo. Yingakho i-cobalt alloy nozzles yethu ihlala ifezekisa i-Ra ≤ 0.8 µm njenge-cast kwiindawo ezihamba phambili ezihamba phambili-iphelisa i-60% yexesha lesibini lomatshini ngelixa ligcina isakhiwo sengqolowa.
Ukudityaniswa okuthe nkqo ayisiyonto iBuzzword-Yi-inshurensi yakho yoMda
Abanye abathengisi bakhupha oomatshini kwiivenkile ze-CNC zomntu wesithathu. Abanye unyango lwe-subcontract yobushushu. Oko kudala iindawo ezintathu zokungaphumeleli: ukugqwetheka kobushushu obuvela kumazinga okucima okungalawulekiyo, ukulungelelanisa inkqubo engalunganga phakathi kwedatum yokuphosa kunye nokulungiswa komatshini, kunye nokungcoliseka komphezulu ngexesha lothutho. Indawo yeQINGDAO QIANGSENYUAN ye-ISO-ethobelana ne-ISO iphatha ukuphosa, i-multi-axis machining, kunye nokugqiba phantsi kophahla olunye-kunye nogcino-lwazi olwabelwanayo lwe-GD&T, iishedyuli ezilungelelanisiweyo zokulinganisa i-metrology, kunye nezigodo ezidityanisiweyo zokulandela umkhondo. Xa umthengi esithumelele umzobo wezindlu wempompo yepiston one-±0.015 mm yokunyamezelana kwindawo kumazibuko asibhozo evalvu, siye sabonisa umngcipheko: iipateni zokuphosa isanti azikwazanga ukubamba loo nkcazo ngaphaya kwe-300 mm ubude. Impendulo yethu ibingeyonto "asinako ukuyenza loo nto" -yayiyi "masitshintshele kutyalo-mali nge-ceramic core assembly, emva koko sigqibezele onke amazibuko ngokucinezela enye sisebenzisa i-5-axis DMG Mori kunye neRenishaw PH10M probe." Isiphumo: Inqaku lokuqala ligqithise kuyo yonke imilinganiselo eyi-12 ebalulekileyo. Akukho kuphinda kusebenze. Akukho siliphu seshedyuli.
Ulawulo Lokwenene Lomgangatho Wehlabathi—Hayi Ukuthotyelwa Kwephepha Kuphela
"Isiqinisekiso se-ISO" sithetha kancinci ukuba abahloli bajonga kuphela imilinganiselo yokugqibela kwaye batsibe ukuqinisekiswa kwe-microstructure. Siqinisekisa iibhilithi ze-cobalt-nickel ezingenayo kunye ne-OES spectroscopy kunye novavanyo lwe-ultrasonic lwe-discontinuities yangaphakathi-ngaphambi kokunyibilika. Ngexesha lokuphosa, ii-thermocouples ezifakwe kwiindonga zeqokobhe zingena kwiiprofayili zexesha lokwenyani lobushushu, hayi nje iiseti zesithando somlilo. I-Post-machining, yonke ivalve yoxinzelelo ifumana uvavanyo lokuvuza kwe-helium kwi-1.5 × uxinzelelo lokusebenza, hayi nje ukudaya ukungena. Kwaye ewe-sigcina ukulandelwa kwezinto ezigcweleyo: inombolo eninzi, ingxelo yokuhlalutya kwenyibilika, i-curve yonyango lobushushu, ingxelo yokuhlola i-CMM, kunye nemephu yoburhabaxa bendawo idityaniswe kwinkqubo yethu ye-ERP kwaye ihanjiswa ngokuthunyelwa ngakunye. Enye i-OEM yaseMntla Melika yokwenziwa kolwelo-manzi yasixelela: “Ipakethi yakho yokulandela umkhondo inqumle uphononongo lwethu lwangaphakathi lwe-QA ukusuka kwiintsuku ezili-14 ukuya kwiiyure ezingama-36.” Ayisiyonto isebenzayo-leyo yintembeko eyinjineli.
Ukukhetha i-Custom Investment Casting Factory yakho-Yeyona nto ihambisa inaliti
- Cela iirekhodi zenkqubo ethile yealloyi: Hayi nje "siphosa ialloys ye-cobalt," kodwa "sibonise i-AMS 5387 yakho yokugqibela yokugalela-kubandakanya izigodo zokutshisa i-mold preheat, ubushushu obuthululwayo, kunye neemephu ze-post-cast microhardness."
- Ifuna ubungqina bemetroloji kwinkqubo: Funa iifoto ze-CMM ezisetyenzisiweyo kwicala lakho lejometri-hayi imifanekiso yesikrini eqhelekileyo evela kwincwadana yoqeqesho.
- Vavanya ukuzibandakanya kwabo kwezobunjineli: Ngenisa umzobo we-GD&T-onzima onedatha entsonkothileyo. Iqabane lokwenyani liya kuphendula kwiiyure ezingama-48 ngemibuzo ethile-hayi itemplate "siya kubuyela kuwe."
- Qinisekisa umda othe nkqo: Ukuba babanga "i-turnkey epheleleyo," qinisekisa ukuba unyango lobushushu, uvavanyo olungonakalisi, kunye nokugqitywa komphezulu kwenzeka kwi-site-okanye kufuna ukuthunyelwa kwiikontraka ezingaqinisekanga.
A Umzi-mveliso wokugalela imali ngokwesiko Izuza isihloko sayo hayi ngomthamo, kodwa ngendlela enzulu ngayo ibethelela uqeqesho lwesinyithi kuwo wonke umsebenzi-ukusuka kwirisithi yemathiriyeli ekrwada ukuya kwipakethe yokugqibela. I-QINGDAO QIANGSENYUAN TECHNOLOGY ayileqi umthamo. Isombulula iingxaki apho iziseko ezisemgangathweni ziyeka: iiplagi ze-cobalt alloy kwiivalvu zokulawula i-subsea, iziseko zempompo ezingekho-standard ezichasayo i-22,000 psi pulsation, i-winch center shaft rollers isinda kwi-10⁷ imijikelezo kwiindawo ezinqabileyo zentlango. Ngexesha elizayo uyilo lwakho lutyhala izinto okanye imida yokunyamezela, ungabuzi ukuba "ngubani onokuphosa oku?" kodwa "ngubani osele ephose into enzima ngakumbi-kwaye wangqina ukuba iyasebenza?"
