Lapho onjiniyela bayacacisa imboni yabakhiqizi be-wax elahlekile ezingxenyeni zensimbi ezibaluleke kakhulu kumishini, azigcini nje ngoku-oda ukulingisa-zivikela ukuqina kohlangothi ngaphansi kwengcindezi engu-300 MPa, ubuqotho be-microstructural ngemva kokuhamba ngebhayisikili elishisayo, kanye nokuqedwa okungaphezulu okusinda ukugeleza kwe-slurry. Yilokho okuyisisekelo-hhayi okuhlukile. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., silethe izingxenye ze-investment-cast ezinembayo ezingaphezu kuka-12,000 kusukela ngo-2016—iningi lazo imizimba yamavalvu e-cobalt-nickel alloy, izindlu zamaphampu, namawintshi lapho ukuchezuka kokubekezelela okungu-0.02 mm kubangela ukwehluleka ukusebenza.
Kungani Ukulahlwa Kwengcina Okulahlekile Kusawina Ezingxenyeni Zezimboni Ezisebenza Kakhulu
Ukulingwa kwesihlabathi akukwazi ukubamba ±0.05 mm kuma-hydraulic manifolds anezindonga ezincane. Ifa uphonsa imifantu ku-AMS 5387 cobalt alloy. I-Centrifugal casting ayinayo inkululeko yangaphakathi yejiyomethri edingekayo kuma-multi-port nozzle. Ukutshala imali-ukuvela kwesimanje kokuphonswa kwe-wax elahlekile-kuzixazulula zonke ezintathu. Inqubo yegobolondo layo le-ceramic ithwebula imininingwane emihle kuze kufike kuzici ezingu-0.3 mm, ifinyelela ukuqedwa okuphansi njenge-Ra 1.6 μm *as-cast*, futhi igcina ukuvumelana kwe-metallurgical kuwo wonke ukushisa ngenxa yokuthi isikhunta asethuli ukufakwa kwesihlabathi noma i-graphite carbon pickup. Sibona lokhu nsuku zonke: amakhasimende ashintsha esuka ezindlini zephampu ye-sand-cast piston aye ezinguqulweni zethu ezilahlekile ze-wax abika impilo yesevisi ende engu-40% ezicelweni zikawoyela ezinengcindezi ephezulu—hhayi ngoba impahla ishintshile, kodwa ngenxa yokuthi i-porosity yehle isuka ku-2.1% yaya ngaphansi kuka-0.3%, kuqinisekiswe ukuskena nge-ultrasonic kwe-ASTM E155.
Yini Ehlukanisa Imboni Yeqiniso Elahlekile Yabakhiqizi Abakhiqiza I-wax Kumthengisi
“Abakhiqizi” abaningi benza amagobolondo angaphandle, ukuwaxosha, noma ngisho nokwelapha ukushisa. Lokho kwephula ukulandeleka—futhi kubulala ukuphindaphinda. Esikhungweni sethu se-Qingdao, isinyathelo ngasinye sihlala endlini: idizayini yephethini ku-SolidWorks ngesinxephezelo sokushwabana esiqhutshwa yi-GD&T, ukucwiliswa kwegobolondo le-silika elisekelwe ku-silica enomswakama olawulwayo kanye nemijikelezo yokushiswa, ukuthululwa kwe-vacuum-assisted ye-cobalt alloy ye-T800 ku-1,480°C, kanye nesixazululo sokusakazwa kwe-post-50 nge-AMSE2 ngayinye. Awekho ama-handoffs. Akukho ukuhluka kwe-batch-to-batch esakhiweni sokusanhlamvu. Lapho i-European OEM idinga ukulandeleka okugcwele kokubalulekile kwepulaki ye-AMS 5387 esetshenziswa kumavalvu okulawula angaphansi kolwandle, sinikeze imibiko yokuhlolwa komshini wokugaya, izinombolo zokushisa, amalogi esithandweni somlilo, kanye nedatha yokuhlola ye-CMM yayo yonke ingxenye—kwehlele ku-ID yomsebenzisi osebenzisa umshini wokulinganisa wokuhlanganisa.
- Ukuhlanganiswa okuqondile kusho ukuthi akukho ukuyekethisa kubukhulu obubalulekile: Sisebenza ngomshini wokubhoboza kokugcina kanye nezindawo zokuvala *ngemuva* kokudambisa ingcindezi—sisusa ukuhlanekezela okubonwa uma kwenziwa izikhala ezicindezelwe ngaphambilini.
- Siqinisekisa ukwenziwa ngaphambi kokuthi kuqale ukusebenza: Onjiniyela bethu bahlaba umkhosi ama-engeli asalungiswa angaphansi kuka-0.5°, ukujiya kodonga kubukhali kuno-3:1, kanye nomgodi oyimpumputhe odlula ububanzi obungu-6×—konga amakhasimende u-$18k–$45k wokuphinda kusetshenzwe kabusha iphrojekthi ngayinye.
- Silawula lokho abanye abakukhiphayo: Isitifiketi se-Raw material, ukuhlolwa kwamandla egobolondo, imephu ye-X-ray porosity, kanye nokuhlolwa kokucindezela kokugcina kokusebenza—konke kwenzeka ngaphakathi kwezindonga zethu eziqinisekisiwe ze-ISO 9001.
Izindleko Zangempela Zokukhetha Okungalungile—Nendlela Yokukugwema
Abanye abathengi bajaha isilinganiso esiphansi kakhulu ngekhilogremu ngayinye. Bese bathola isilinganiso se-scrap esingu-17% ku-cobalt alloy nozzles ngenxa ye-microporosity engabonakali eduze kwamaphiko okupholisa. Noma ubhekane nokulibaziseka kwamaviki angu-11 ngenxa yokuthi “ifekthri” inenkontileka encane yokwenza umthengisi ngaphandle kwe-AS9100. Noma thola "insimbi engagqwali" yabo ihluleka ukuhlolwa kwesifutho sikasawoti ngemva kwamahora angu-96-hhayi ngoba ingxubevange yayingalungile, kodwa ngenxa yokuthi i-Foundry yeqe ukufakwa kwesisombululo. Sihambe amaklayenti kuzo zontathu lezi zimo. Ukulungiswa akukona nje ukucaciswa okungcono kakhulu—ukuqina kobunjiniyela okwabiwe. Isibonelo, lapho umakhi wepompo waseNyakatho Melika edonsa kanzima ngokuqhekeka ezindlini zamasilinda ensimbi engenasici angu-316L, ithimba lethu lenze imephu ama-gradients ashisayo ngesikhathi sokuqinisa, ladizayina kabusha isango ukuze linciphise izindawo ezishisayo, futhi lengeza umjikelezo opholile opholile. Isivuno seqe kusuka ku-63% kuya ku-94%. Akukho ukuklama kabusha. Akukho ukusebenzisa okusha. Ulwazi olujulile lwenqubo olusetshenziswa lapho lubalulekile.
Lapho I-Precision Lost Wax Casting iletha i-ROI Elinganisekayo
I-ROI ayiyona ithiyori lapha. Ilandelelwa ekusebenzeni kwenkambu: • Amavalvu okucindezela kwe-hydraulic afakwe ku-cobalt alloy T800 ahlala ngo-3.2× ubude kunamayunithi alinganayo e-sand-cast emijikelezweni yomsebenzi wemishini ephathwayo • Izisekelo zephampu ezenziwe ngomshini kusuka ku-investment-cast ductile iron zibonisa u-22% okudlidliza okuphansi kwe-amplitude ku-3,600 RPM—kuqinisekiswe i-laser ye-vibrstand i-laser Dopplen <0.015 mm okuphumayo *njengomshini*, ukusika isikhathi sokuhlanganisa ngamaminithi angu-37 ngeyunithi ngayinye emigqeni ye-OEM Kungakho amakhasimende omhlaba—kusuka ku-Tier 1 abahlinzeki bomgwaqo ongekho emgwaqweni onguthelawayeka ukuya kuma-OEMs wephampu akhethekile—esiphatha njengesandiso sethimba labo lonjiniyela, hhayi umthengisi. Asihlangani nje nemidwebo. Siyabaphenya.
Uma udinga a imboni yabakhiqizi be-wax elahlekile ephatha izidingo zokusebenza zengxenye yakho njengezingenakuxoxisana—hhayi njengeziphakamiso—uzothola isiyalo, ukujula kwensimbi, nokulawula okuqondile ku-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Lapho i-geometry eyinkimbinkimbi ihlangabezana nokusebenza okungaguquki, inqubo iqala isikhathi eside ngaphambi kokuba i-wax incibilike.
