Iyo ba injeniyeri bagaragaje cobalt-nikel ivanze na pompe hydraulic, pompe yumuvuduko mwinshi, cyangwa sisitemu ya winch ya offshore, ikibazo kimwe kigaragara inshuro nyinshi: Ni hehe ukura ibice 4 byo mu ruganda rugira kwihanganira munsi ya 0,01 mm - kandi ukabaho amasaha 20.000+ muri serivisi yangirika, yambaye cyane? Ntabwo buri mutanga isoko akora AMS 5387 cobalt alloy cyangwa T800 ishingiye kuri casting hamwe na disipuline ya metallurgji isabwa. Twabonye prototypes yananiwe kwemeza kuko ibintu byinshi byakurikiranwe byabuze. Twabonye gutanga bidindiza caskade mugihe casting shrinkage itishyuwe mugihe cya gahunda ya CNC. Niyo mpamvu abaguzi basobanutse bagenda barenga abahuza mubucuruzi hanyuma bakajya kwerekeza kubakora ibicuruzwa bigenzura gushonga byombi hamwe no gutunganya kontour ya nyuma - nka QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Co 4 ubushobozi bwuruganda butangirana na nyirubwite-ntabwo ari ugukora gusa
Abatanga ibicuruzwa benshi biyita "inzobere za cobalt" ariko bakohereza hanze kubandi bashinga. Ibyo bitera icyuho gikomeye: nta kugenzura imiterere yingano, gukwirakwiza karbide, cyangwa gutandukanya interdendritic. Kuri QINGDAO QIANGSENYUAN, uruganda rwa Co 4 rutangirana nibikorwa byemewe - AMS 5387 ingots zagenzuwe na raporo yikizamini hamwe nisesengura rya spekrometrike mbere yo gusuka. Imirongo yabo yumucanga nishoramari ikora munsi yumuriro ushushe, igahita ikurikirwa no gukemura no gukonjesha kuri ASTM A995. Kuki iki kibazo? Kuberako inzu ya pisitori ya piston idashobora kunanirwa kuva hejuru - ahubwo itangirwa na microcrack itangirira kumipaka idakomeye hagati yimiterere yashizweho mugihe gikomeye. Guhuza kwabo guhagaritse bisobanura guta ibipimo, uburyo bwo kuvura ubushyuhe, hamwe ninzira nyinshi za CNC ibikoresho byateguwe neza nka sisitemu imwe - ntabwo ari intambwe eshatu zaciwe.
Imikorere nyayo-yisi ishingiye kumurongo uhamye murwego rwibikorwa
Twigeze gusuzuma isuzuma rya GD&T ryumukiriya kubiterane bya cobalt alloy nozzle: guhamagarwa kwukuri kwa ± 0.005 mm kuri bores esheshatu za coaxial, uburibwe bwo hejuru Ra ≤ 0.4 µm kumaso yikimenyetso, no gukomera 42-46 HRC nyuma yo gusaza kwanyuma. Igice cyatsinze ubugenzuzi bwa CMM nyuma yo gutunganywa - ariko byananiranye gukora ibizamini nyuma yamasaha 72 yumunyu-spray. Impamvu? Kugabanya imihangayiko isigaye ntibyakurikiranye hagati yo gukata no kurangiza. Uruganda rwa Co 4 rwa QINGDAO QIANGSENYUAN rushyiramo imbaraga zo kugabanya imihangayiko * hagati yimikorere yimashini - ntabwo irangiye gusa. Bakoresha igenzura rya CMM kubikorwa byibyuma (ntabwo ari aluminium), bagakurikirana drift yamasaha, kandi bagakoresha algorithms yindishyi zahinduwe mumashini yihariye ya Haas na DMG MORI. Igisubizo: imibiri ya valve ihora igera kuri 0.008 mm yuzuye yuzuye ya metero 300 z'uburebure-na nyuma ya passivation ya nyuma.
Ibice byose bya cobalt ntibingana - urwego rwibintu rusobanura imipaka yo gusaba
- AMS 5387 cobalt alloy 6: Byakoreshejwe aho kurwanya isuri biruta imbaraga zingana - tekereza moteri ya moteri yindege cyangwa intebe ya valve yo munsi. Ubushyuhe ntarengwa bwa serivisi bukomeza: 815 ° C.
- T800 ya cobalt: Yatoranijwe kubice bitwara imitwaro nka winch center shaft rollers. Ibintu byinshi bya nikel bitezimbere ubuzima bwumunaniro munsi ya cyclic torsion - ariko bisaba kugaburira buhoro buhoro kugaburira no gukomera.
- Uburinganire bwa geometrike: Ba injeniyeri babo ntibigana ibishushanyo gusa. Bashyira ibendera ku bice byoroheje bikunda kugoreka mugihe cyo kuzimya, bagatanga umushinga wo gukuraho igishoro cyogushora imari, kandi bakemeza ibipimo byubugari bwurukuta kurwanya amakuru yo kwigana.
Ubu ntabwo ari ubumenyi bwubumenyi. Yubatswe kuva 127 yanditseho amazu ya pompe yubatswe kuburayi bwa OEM-na 43 kunanirwa gusesengura ibice byagaruwe na cobalt. Mugihe umukiriya yasabye icyuma gikoresha imiyoboro yo gukonjesha imbere, ntabwo bavuze muri rusange. Bakoresheje ubushyuhe bwa FEA, batanga icyerekezo cya HIP kugirango bakureho urukuta rwumuyoboro, kandi batanze ingero zingingo ya mbere muminsi 18 - atari ibyumweru umunani.
Amasoko ataziguye atanga ibiteganijwe - ntabwo ari igiciro gusa
Amatsinda yo gutanga amasoko akeka ko "uruganda rutaziguye" bisobanura igiciro gito. Ariko inyungu nyayo ni kugenzura. Hamwe na QINGDAO QIANGSENYUAN, isubiramo ryubwubatsi riba hamwe na metallurgiste umwe wasinyiye ubushyuhe bwa AMS 5387. Impamyabumenyi zirimo amateka yubushyuhe bwuzuye - ntabwo ari chimie yanyuma. Ibicuruzwa byose bitwara ibyiciro byo murwego rwo hejuru: nimero yo gushonga, itariki yo guta, ubushyuhe bwo kuvura itanura, hamwe na raporo ya CMM. Ntabwo umukara-agasanduku gashinzwe gukorana. Nta gitangaza cyo kongera gukora kuri NDT idateganijwe. Ku bakiriya bo muri Amerika ya Ruguru, bayobora igihe cyo gutumiza ibicuruzwa bito (50-500 pc) impuzandengo y'ibyumweru 6-8 - harimo ibipimo byuzuye, bikomeye, hamwe no kugenzura ultrasonic. Guhindura prototype? Byihuse nkiminsi 11 yakazi-hamwe nibyangombwa bya FAI byahujwe na AS9102.
Urebye imbere, uruganda rwa Co 4 rukomeje kuba ruto kandi rwimbitse: kumenya uburyo bwimvange aho gushora imari bihura no gusya 5-axis, kwagura EN 10204 3.2 gukwirakwiza ibyemezo, no kwemeza uburyo bushya bwa cobalt kuri serivisi ya hydrogen. Niba umushinga wawe utaha usaba ibice bidahuye gusa na-ariko bikomeza imikorere aho abandi bitesha agaciro-tangira ukoresheje ibiganiro bya tekiniki, ntabwo ari ugusubiramo amagambo. Ubusobanuro muri cobalt ntabwo bwakozwe. Byarakozwe, biragenzurwa, kandi birasubirwamo.
