Iyo abajenjeri bagaragaje igice kigomba kwihanganira ± 0.01 mm kwihanganira umuvuduko wa hydraulic ya bar-350-kandi bakarokoka 10,000+ inzinguzingu-ntibakenera gusa. Bakeneye an Uruganda rwo gushora imari IMPRO ifata metallurgie nka code hamwe nuburinganire buringaniye nkamategeko yamasezerano.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora kimwe muri ibyo bigo muri Qingdao-ntabwo ari iduka rusange ryicyuma, ariko nkumufatanyabikorwa wuzuye kubice byingenzi-ubutumwa aho gutsindwa bidahenze-birababaje. Twabonye abakiriya bagaruka inshuro eshatu hamwe na AMS 5387 imwe ya cobalt alloy pompe ishushanya amazu: icya mbere kubintu bifatika kuri radiyo yintebe ya valve, icya kabiri kuri microcracking nyuma yo kuvura ubushyuhe, icya gatatu kuko kurangiza hejuru ntabwo byujuje ibintu byerekana kalibrasi. Igihe cyose, intandaro ntabwo yari "ubuziranenge bwa casting" - byari ukudahuza imyitwarire yimyitwarire, gushushanya amarembo, hamwe nuburyo bukurikira bwo kugabanuka. Aho niho uru ruganda rutanga.
Kuki cobalt-nikel alloys isaba ibirenze "gushora imari"?
Abatanga ibicuruzwa benshi bafata AMS 5387 cyangwa T800 nkikindi cyiciro gusa kurupapuro rwihariye. Mubyukuri, aya mavuta agabanukaho 17% arenga 316 adafite umwanda mugihe cyo gukomera, guteza imbere imashanyarazi yumuriro 3 × igororotse mubice bikikijwe n'inkuta zoroshye, kandi ikarwanya imashini ikaze kuburyo ibikoresho bya karbide byambara 40% byihuse niba kuvura mbere yubushyuhe bidateganijwe neza. Twapimye ibi-ku nyubako ya piston pompe ya silinderi yubatswe kubikorwa bya peteroli na gazi yo hanze.
QINGDAO QIANGSENYUAN ntabwo itanga impamyabumenyi ya alloy. Itsinda ryabo rya tekinike rifatanya kwemeza ibikoresho fatizo hamwe nababitanze bemewe - gukurikirana ingano y ingano, ikwirakwizwa ryimyanya ndangagitsina, hamwe na ogisijeni kugeza 15 ppm. Mugihe umukiriya yohereje T800 nozzle hamwe nisuri itaragera kumuhogo, twongeye kuyisubiza kumvura ya niobium ya karbide idahuye mumuriro umwe. Gukosora? Guhindura igisubizo cya anneal igipimo cya 0.8 ° C / sek - no gufata ibyangombwa kuri buri kilo.
Uru rwego rwo kugenzura rukora gusa kuko rwabo Uruganda rwo gushora imari IMPRO ihuza intambwe intambwe abandi silo: ibishashara bya geometrie byemewe kurwanya ibikoresho bya CNC * mbere yo kubaka igikonoshwa; uburyo bwo kuvura ubushyuhe burahuzwa nibikoresho byanyuma byo gutunganya; Ubuso bwo kurangiza ibipimo (Ra ≤ 0.4 μ m) bigenzurwa hakoreshejwe optique ya profilometrie - ntabwo ari tactile gusa - kuko imivurungano isaba sub-micron gusubiramo.
Kwishyira hamwe bihagaritse ntabwo ari amagambo-ni kwihanganira gutondekanya ubwishingizi
Abacuruzi bamwe basubiramo casting-yonyine, hanyuma bagakorana amasezerano kumaduka atatu atandukanye. Ibyo bizana ikosa ryo guteranya: guta kugabanuka + gutunganya imashini ihinduranya + kugoreka ubushyuhe = ibice bihuye na CMM ariko bihuza mu nteko. Muri QINGDAO QIANGSENYUAN, itsinda rimwe ryubwubatsi rifite urunigi rwuzuye - uhereye kubisobanuro bya GD&T kubisobanuro byo guhamagarira gushushanya kugeza ikizamini cya nyuma cyakozwe ku ntebe ya hydrostatike.
Twakurikiranye imibiri 42 yumuvuduko wa valve hejuru yimikorere ibiri. Izi mashini zose murugo zerekanaga 92% murwego rwo gusubiramo hejuru yikimenyetso gikomeye. Abafite kurangiza hanze baramanutse bagera kuri 68%. Itandukaniro? Amakosa yo kwimura datum yoherejwe hagati ya 0,018 mm-bihagije kugirango ubangikanye no gufunga gufunga kuri 250 bar.
- Gukora CNC: 5-axis icyarimwe guhuza ibice byimbere byimbere mumfatiro ya pompe
- Kuvura ubushyuhe: Vacuum annealing hamwe nigihe nyacyo cyo gushushanya mapping muri buri mutwaro
- Kurangiza: Electropolishing for ruswa yo kurwanya ruswa * na * micro-yoroshye-yagenzuwe na amashusho ya SEM
Nta ntambwe yatanzwe idafite ibimenyetso byerekana: nimero nyinshi, indangamuntu zikoreshwa, imashini zerekana imashini, hamwe na raporo ya CMM yabitswe ku bipimo bya AS9102 - ndetse no ku bicuruzwa bitari mu kirere. Kuberako iyo winch center shaft roller yananiwe guterura hagati kuri bucukuzi bw'amabuye y'agaciro, "twakurikije inzira" ntabwo bihagije. Ukeneye gihamya yerekana * uburyo * nuburyo bukora.
Gutanga-kwisi bisobanura ubwubatsi-ntabwo ari amatariki gusa
"Gutanga ku gihe" ntacyo bivuze niba ibyoherejwe bwa mbere bigeze hamwe nu mugozi utari wo ku cyuma cya cobalt. QINGDAO QIANGSENYUAN yubaka gahunda yo guhangana na injeniyeri-ntabwo ari ibikoresho. Abashinzwe imishinga ntibakurikirana gusa igihe cyo kuyobora; berekana ibendera rishobora gukora * mbere yuko * ibikoresho bitangira.
Umwaka ushize, umukiriya wu Burayi yatanze GD&T ivuguruye kuri hydraulic manifold block. Itsinda ryacu ryabonye ko kwihanganira imyanya (± 0,025 mm) kuri datum C bisaba gusya nyuma yo gukina - wongeyeho $ 1,200 / ubumwe no gutinda ibyumweru 3. Ahubwo, basabye guhindura icapiro ryibanze kugirango bahindure datum hejuru yimashini, bagera kumurongo umwe uhuza ibiciro 40%. Umukiriya yemeye mumasaha 48.
Ibi bibaho kuberako injeniyeri zabo zivuga ibishingwe na fluid dinamike. Bazi impamvu 0.1 mm ya offset muri nozzle isohora inguni ihindura imikorere ya spray kuburyo bwa 11%. Bagerageje coefficient zitemba kuri 17 cobalt alloy geometrie-ntabwo bivuye mu kwigana byonyine, ahubwo hamwe n'intebe za kalibatifike zikoresha amazi akora.
Niba urimo gushakisha ibyuma bisobanutse neza aho imikorere ihagaze ku busugire bwa microstructure, ntabwo ari ibipimo bya macro gusa, guhitamo ntabwo biri hagati y'abacuruzi-biri hagati yibitekerezo n'ibimenyetso. An Uruganda rwo gushora imari IMPRO ntabwo isezeranya gutungana. Itanga ibisubizo bikurikiranwa, bisubirwamo, byemejwe neza-ikintu kimwe cyingenzi icyarimwe.
