Iyo abajenjeri bagaragaje ibice bya pompe hydraulic, valve yamavuta ya peteroli, cyangwa sisitemu ya winch iremereye, ntibakenera ibyuma gusa-bakeneye uburinganire buke. Gutandukana kwa mm 0,02 mu ntebe ya cobalt-alloy nozzle irashobora gutera cavitation. Mm 0,05 mm idahuye mumazu ya piston pompe irashobora kwihutisha kwambara 40%. Niyo mpamvu kuyobora OEM hamwe nabatanga Tier-1 bahora bagaruka kuri a yatakaye ibishashara byuzuye uruganda ibyo bifata kwihanganira atari intego-ahubwo ni ibyingenzi.
Impamvu Gutera Ishoramari Biracyatsinze Aho CNC Yonyine Yatsinzwe
Twabonye imishinga myinshi ihagaze kuri prototype kuberako abayishushanyijeho batekerezaga ko imashini nyinshi zishobora gukora geometrike igoye-nkibice bitemba byimbere mumazu ya pompe ya AMS 5387 cyangwa imiyoboro ikonjesha mumibiri ya T800. CNC ikora neza kumiterere yo hanze. Ariko iyo uburebure bwurukuta bugabanutse munsi ya mm 2,5, radiyo y'imbere igabanuka kugeza kuri R0.3, kandi ubunyangamugayo bwa metallurgji bugomba kubaho 350 ° C kumagare yubushyuhe? Aho niho guta ibishashara byatakaye bitanga ibyo gusya bidashobora: net-imiterere igoye itabangamiye imiterere yingano.
Ku kigo cyacu muri Qingdao, buri kintu cyose cobalt-nikel gitangirana nigishashara cyubatswe kuva mumibare ya CAD yemewe - ntabwo igereranijwe na dosiye ya STL. Dukoresha vacuum ifashwa na ceramic shell yogushiramo, kugenzura ibishashara kuri 120 ° C, hamwe nitanura ryashyuha kugeza kuri 1,050 ° C mbere yo gusuka. Ibi bivanaho micro-shrinkage icyuho gikunze kuboneka mumusenyi. Igisubizo? Kurangiza hejuru ya Ra 3.2 µm, kwihanganira umurongo wa mm 0,05 mm kugeza kuri mm 200, no kubahiriza byuzuye ISO 8062-2: 2013 kubyihanganira igice.
Kwishyira hamwe Vertical Ntabwo ari Buzzword-Nubwishingizi bwa Dimensional
Ibishingwe bimwe byohereza ibicuruzwa mu maduka y’abandi bantu kugirango babikore. Ibyo bizana impinduka eshatu zitagenzuwe: kugoreka ubushyuhe mugihe cyo gutwara, guhuza datum idahuye, no gutinda gutanga ibitekerezo mugihe guhamagarwa kwa GD&T guhura na as-geometrie. Twirinda ibyo uko ari bitatu dukoresha casting, kuvura ubushyuhe, no kurangiza munsi yinzu imwe - no muri sisitemu imwe.
Ingirabuzimafatizo zacu za CNC zikoresha icyarimwe gusya 5-axis hamwe no kugenzura CMM kuri buri mubiri wa valve. Iyo umukiriya atanze igishushanyo gifite kwihanganira imyanya nyayo Ø0.03 mm kumyobo itandatu ya bolt ugereranije na datum yashizwe kumurongo wangiritse - twe imashini, turapima, duhindura, kandi twongera gupima - byose muburyo bumwe. Nta ntoki. Nta cyiciro cyacitsemo ibice. Nta cyuho gishobora gukurikiranwa. Buri kintu cyose gitwara ibikoresho byuzuye, ibiti bivura ubushyuhe, kandi bigahuza raporo zabitswe mu myaka 10.
Uku kwishyira hamwe bifite akamaro cyane hamwe na superalloys. T800 ibikoresho bishingiye kuri cobalt birakomera bitateganijwe nyuma yo gukemura annealing. Niba gutunganya bibaye mbere yo gusaza kwa nyuma, guhangayika gusigara kugabana no kugabanya ibimenyetso bifatika. Inzira yacu ifunze muburyo bukurikiranye: guta → guhangayikisha-kugabanya → imashini → imyaka → ubugenzuzi bwa nyuma. Twagabanije nyuma yubushyuhe-bwo kuvura ibice bya AMS 5387 biva kuri 11% bikagera kuri 0.8% mumezi 24 ashize - kuko tugenzura urunigi rwose.
Imikorere nyayo-Isi Itangirana na Real-World Material Discipline
"Impamyabushobozi Yemewe" isobanura bike niba raporo yikizamini cyo gusya idahuye na tag ya ingot - cyangwa niba gutandukanya ibishishwa bitamenyekanye muri mm 50 yambere yo gusuka. Dutanga isoko ya cobalt-nikel gusa ivuye mu ruganda rwemejwe na ASTM B575 na AMS 5387 Nyiricyubahiro D. Buri bushyuhe bukorerwa ibyuka bihumanya ikirere iyo byakiriwe. Buri gice cyo gutora kibona PMI igenzura * mbere yubaka igikonoshwa-na nyuma yo gukora.
Turakomeza kandi ubufatanye bwa tekiniki nabatanga ibintu bibiri byambere bitanga cobalt - imwe i Burayi, imwe muri Amerika ya ruguru - kugirango dufatanye guteza imbere ubushyuhe bwihariye bwo gutunganya. Kurugero: mugihe utera T800 nozzles kumapompo yameneka yumuvuduko mwinshi, duhindura igipimo cyo gukomera hamwe nigihe cyo gukonjesha gishingiye kumyuka ya karubone na silikoni yuzuye yubushyuhe - ntabwo ari rusange. Nuburyo tugera kumurongo uhoraho wa 42-45 HRC hejuru ya 98% yumusaruro, ntabwo ari laboratoire gusa.
Abakiriya bakunze kubaza bati: “Urashobora gufata mm 0.025 mm kuri 120 mm ya diametre ya T800?” Yego - niba igishushanyo kirimo gahunda ya datum ikora, yerekana ubusugire bwibisabwa hejuru (ntabwo ari ubugome gusa), kandi bikadufasha kwemeza uburyo bwo kwigana uburyo bwo kugereranya amafaranga yatanzwe. Tuzakubwira imbere niba bishoboka. Cyangwa aho ugomba guhinduka.
Guhitamo Ibishashara Byatakaye Byakorewe Uruganda Bisobanura Guhitamo Umwirondoro wawe
Abacuruzi bahendutse ba casting bahatanira igiciro kubiro. Nukuri yatakaye ibishashara byuzuye uruganda irushanwa ku kunanirwa. Buri cobalt alloy plug itanga tuyikurikirana yuzuye - kuva mubushyuhe kugeza kumibare yanyuma yikizamini. Buri kinyabiziga cyubwubatsi winch shaft yoherejwe na raporo zingana zashyizweho umukono nabagenzuzi bacu bemewe na ASQ. Buri cyegeranyo gikubiyemo ibitekerezo bitanga umusaruro-ntabwo "dushobora kubikora," ariko "dore uburyo bwo kugabanya ibiciro 22% utarinze igitutu giturika."
Iyo disipuline niyo mpamvu igipimo cyacu cyo gusubiramo kirenga 76% muri Amerika y'Amajyaruguru, Uburayi, na Aziya y'Amajyepfo y'Uburasirazuba. Ntabwo ari ukubera ko duhendutse. Kuberako iyo pompe yawe ikora kuri 4000 psi mumasaha 18.000, ntakintu nka "cyiza gihagije." Hariho imikorere yagaragaye gusa-nuruganda ruhagaze inyuma.
