Iyo ba injeniyeri bagaragaje 17-4 gushora imari kumashanyarazi ya hydraulic yumuvuduko mwinshi cyangwa amazu ya pompe ya turbine, ntabwo bahitamo gusa ibikoresho-bahitamo gushikama kurwego, kurwanya ruswa, hamwe na microstructural idahwitse mugihe cyamagare yubushyuhe. Niyo mpamvu guhitamo iburyo 17 4 uruganda rukora ishoramari ibintu birenze kuvuga ibiciro byonyine. Muri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twashyize ibice birenga 2,300 bidasanzwe 17-4 PH kuva muri 2019 - buri kimwe gisaba kugenzura GD&T, kugenzura ubushyuhe bwuzuye, no kumvikana na zeru kuri AMS 5643.
Impamvu 17-4 PH isaba ibirenze gushora imari isanzwe
17-4 PH ibyuma bitagira umwanda ntabwo "ari ikindi kintu kitagira umwanda." Imyitwarire ikaze yimvura isobanura intambwe zose - uhereye kumashara ya geometrie kugeza kumyaka yanyuma yubusaza - bigira ingaruka zitaziguye imbaraga zumusaruro, ubuzima bwumunaniro, hamwe na mashini. Twabonye abakiriya bananiwe gukora prototype kuberako uwabitanze yakoresheje ibishishwa rusange byashushanyije kuri 316, ntabwo kwaguka kwinshi kwumuriro no kugabanuka gahoro gahoro ya 17-4 PH. Igisubizo? Micro-shrinkage mumibiri ya valve yoroheje, hanze ya HRC 38-42 nyuma yo gusaza H900, cyangwa guturika hejuru mugihe cyo kugabanuka nyuma yo guta umutwe.
Ishami ryacu ryemewe na ISO 9001 rikemura ibi hamwe nuburyo butatu bwubatswe: Icya mbere, ibicuruzwa byabugenewe byabugenewe byahujwe nubushyuhe bwa 17-4 ° 1450 ° C. Icya kabiri, gukonjesha gukonjesha imbere mu ziko zifashwa na vacuum-nta kuzimya ikirere. Icya gatatu, itegeko nyuma yubushyuhe-buvura CMM kwemeza kuri datum zikomeye mbere yo gutunganya. Nuburyo dufata ± 0,05 mm kuri diametero 300 mm tutabanje gusya kabiri.
Kwishyira hamwe guhagaritse gukemura ibibazo byububabare nyabwo
Abaguzi benshi bafata casting na CNC nkabacuruzi batandukanye. Ibyo bitera icyuho cya handoff: gahunda ya datum idahwitse, amafaranga yimigabane idahwitse, cyangwa gutinda kubitekerezo kubyerekeranye nurukuta. Ku kigo cyacu cya Qingdao, itsinda rimwe ryubwubatsi rifite urunigi rwuzuye - uhereye ku gishushanyo mbonera cy’ishoramari binyuze muri passivation ya nyuma.
- Dukora imashini 17-4 zose zashizwe munzu dukoresheje 5-axis DMG MORI NTX 1000s, dukuraho sisitemu yo guhuza ibikorwa hagati yabacuruzi.
- Abacuruzi bacu ba metallurgiste bafatanya gusinyisha imbonerahamwe yubushyuhe hamwe nibikoresho fatizo - buri cyiciro gikurikirana kuri SAE AMS 5604 yemewe.
- Kurangiza ubuso ntabwo byigeze bitekerezwa: Ra 0.8 µm nibisanzwe kumaso; Ra 0.4 µm iboneka hamwe na electropolish-yagenzuwe hakoreshejwe profilometero, ntabwo igereranya
Uku kwishyira hamwe kugabanya igihe cyo kuyobora 37% kubicuruzwa bito bito (50-500 pcs) kandi bikuraho ibikorwa bivuye mubitekerezo bidahuye. Pompe imwe yo muri Amerika ya ruguru OEM yagabanije kunanirwa kwumurima ku kigero cya 92% nyuma yo kuva mubyiciro bibiri bitanga isoko kubisubizo byacu 17-4 PH igisubizo.
Ibyo abakiriya babaza mubyukuri mbere yo gushyira urutonde rwabo rwa mbere
“Urashobora gutera imiyoboro ikonjesha imbere ya mm 2,5 mm?” Yego-twabyaye mm 1.8 zihumye mumazu ya 17-4 ya silinderi dukoresheje tekinoroji yatakaye yagenzuwe na CT scan yinganda.
"Ushyigikiye H1150M + gusaza kabiri kubera gukomera cyane?" Nibyo - itanura ryacu ryandika igipimo cyikigereranyo, igihe cyo gushiramo, hamwe no gukonjesha imyirondoro kuri buri gice, hamwe nimikono ya digitale kuva QA na metallurgie iyobora.
“Ni ubuhe butumwa bwawe ntarengwa kuri geometrie idasanzwe?” Nta MOQ ihamye. Dukoresha prototypes kubiti bisangiwe mugihe bishoboka - kandi tugabana ibiciro byigikoresho. Ariko ntituzavuga niba uburebure bwurukuta buguye munsi ya mm 4.2 cyangwa inguni zagabanutse munsi ya 1.5 °. Izi mipaka ntabwo zishakiye; bashingiye kuri 127 bananiwe kugenzura ingingo yambere yinjiye mububiko bwacu bwa NCMR.
Turasubiza ibi bibazo imbere - ntabwo ari guhamagarwa kugurisha, ahubwo muri raporo yacu yo gusuzuma ibyubuhanga, byatanzwe mugihe cyamasaha 72 yoherejwe.
Kureba Imbere: Aho Gukora Precision Bikurikira
Imipaka ikurikira ntabwo ibice binini-ni intera nziza. Ubu turimo gushira mikoro-mikorobe mu buryo butaziguye 17-4 ishoramari: nimero yuruhererekane ya laser yasomwe nyuma yo kurasa, guhuza coolant-path verisiyo yo kugenzura, hamwe na datum igaragara mbere yakozwe kuri ± 0.015 mm mbere ya CNC yanyuma. Ibi bikuraho intambwe yerekana ibimenyetso kandi bigabanya aho bigenzurwa 60%.
Intego yacu ya R&D ikomeza kuba ndende kandi yimbitse: gutezimbere uburyo bwimvange aho gushora imari bitanga hafi-net, kandi gutunganya neza byongera ubuso bukora gusa aho bikenewe. Nta "ubunini-bumwe-bwuzuye". Nta kuvura ubushyuhe butari bwiza. Gusa bisubirwamo, byanditse, bigenzurwa 17-4 imikorere ya PH-yatanzwe kuva murimwe 17 4 uruganda rukora ishoramari muri Qingdao ifata urupapuro rwawe rwihariye nkamasezerano, ntabwo ari igitekerezo.
