Iyo sisitemu ya hydraulic yananiwe munsi yumuvuduko wa bar-350, mugihe amazu ya pompe yamenetse nyuma yamasaha 12,000 yo gukora, cyangwa mugihe cobalt-nikel nozzles yangirika vuba kurenza uko byari byitezwe-abajenjeri ntibashinja igishushanyo. Babikurikirana ku cyemezo kimwe: ubunyangamugayo bwibintu bufatanije nubudahemuka buringaniye muri nikel-ishingiye kuri alloy mashini yinganda.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yamaze imyaka irenga icumi akemura icyo kibazo - ntabwo ari mubitekerezo, ahubwo hasi yububiko. Twabonye AMS 5387 casting warp mugihe cyo kuvura ubushyuhe kubera imiterere yingano idahuye. Twongeye gukora T800 alloy center shaft izunguruka inshuro eshatu kubera micro-crack zihishe munsi yubuso. Ibi ntabwo ari hypothettike. Namasomo yo murwego yashizeho uburyo dukora imashini, gutera, no kwemeza buri gice.
Kuki nikel ishingiye kuri nikel isaba ibirenze ubushobozi bwa CNC gusa
Amavuta ashingiye kuri Nickel nka Inconel 718, Hastelloy C-276, na AMS 5387 arwanya ruswa kandi agumana imbaraga ziri hejuru ya 650 ° C - ariko kandi zirakora cyane, zikora ubushyuhe nabi, kandi zikambara ibikoresho byo gutema bikabije. Amaduka asanzwe ya CNC ntashobora kwihanganira ± 0.01 mm kwihanganira amazu ya 420-mm ya diametre ya piston pompe ya silinderi yakozwe muri T800 alloy idafite ingamba zabigenewe, uburyo bwo guhagarika amashyuza, hamwe na metero.
Niyo mpamvu guhuza vertical bifite akamaro. Ku kigo cyacu cya Qingdao, gukina ntabwo biva hanze. Gutera umucanga no gushora imari bibera munsi yinzu - kuruhande rwibigo byinshi bitunganya imashini zihinduka buri munsi. Tugenzura ubushyuhe bwubushyuhe, igipimo cyo gukomera, hamwe no kugabanuka nyuma yo kugabanuka mbere yo gukata bwa mbere. Nta ntoki. Nta cyiciro-cy-itandukaniro muburyo bwa dendritic. Gusa microstructure isubirwamo-kandi niho hatangirira umutekano.
Turagerageza buri munsi: umukiriya yasabye ibyuma 18 bisa na cobalt alloy yamashanyarazi ya peteroli nyinshi. Igice cya 1 cyatsinze igenzura rya CMM ariko cyananiwe guturika kuri 412 bar. Micro-CT yerekanye ububobere buke hafi yigitugu cya kashe - bitamenyekana ukoresheje gage. Twahinduye igishushanyo mbonera, twagabanije ubushyuhe bwa 23 ° C, hanyuma twongeramo vibrasi ya ultrasonic mugihe cyo gukomera. Icyiciro cya 2 gifite 487 bar. Urwo rwego rwo kugenzura rubaho gusa iyo gutora no gutunganya imashini bicaye hamwe mugihe cyo gusuzuma DFMA.
Icyo "precision" isobanura mubyukuri kubice byingenzi
Icyitonderwa ntabwo ari kwihanganira gusa. Ni uguhuza imikorere hagati ya geometrie, metallurgie, nibidukikije bya serivisi. Umubiri wumuvuduko wumuvuduko ugomba gufunga - ariko ugomba no kurokoka kumagare yubushyuhe utarinze kumeneka. Uruziga rwagati rwa shitingi rugomba kuzunguruka neza - ariko ubukana bwarwo bugomba kurenga HRC 52 * kandi * bugakomeza gukomera munsi yubutaka kugirango birinde kwangirika.
Niyo mpamvu protocole yacu nziza ikubiyemo verisiyo ku ngingo enye zitaganirwaho:
- Kwemeza ibikoresho: Igiceri cyose cyangwa ingot itwara MTR yuzuye, harimo isesengura rya ecran na raporo yubunini bwimbuto - ntabwo ari impamyabumenyi gusa.
- Muri gahunda yo kugenzura CMM: Nyuma yo gukomeretsa, kurangiza-kurangiza, no kurangiza-kuri mashini imwe ya Calibrated, ukoresheje gahunda imwe ya datum
- Ikizamini cyimikorere: Umuvuduko wumuvuduko wageragejwe kuri 1.5 × umuvuduko wagenwe; inzu ya pompe izunguruka iringaniza kandi igenzurwa na helium mass spectrometry
- Gukurikirana byuzuye: Buri gice gihuza numero yacyo yubushyuhe, verisiyo ya progaramu ya progaramu, indangamuntu ikora, hamwe nigihe cyo kugenzura
Ibi ntabwo birenze ubuhanga. Irinda igiciro cyamadorari 280.000 yo kumanura mugihe inzu imwe ya silinderi yamenetse ihagarika pompe yicyondo ya peteroli kumasaha 72.
Aho kwihagarika kureka kuba ibyago-bigatangira gutanga ROI
Abatanga ibicuruzwa bamwe bafata ibice bitari bisanzwe nkibidasanzwe. Turabafata nkamahirwe yo gukuraho uburyo bwo gutsindwa. Umwaka ushize, OEM yu Burayi yatuzaniye igishushanyo cyihariye cya AMS 5387 nozzle ifite imiyoboro ikonje idasanzwe. Abacuruzi babo babanje kuvuga ibyumweru 14 banga uburyozwe bwo gutandukana kurenga ± 8%. Twakoresheje amashusho yubushyuhe, twongeye gushushanya imbere kugirango tunonosore umuvuduko, kandi twatanze mu byumweru 9 - hamwe no gutandukana gutemba byapimwe kuri ± 2.3% kubice 12 byose.
Nigute? Mugufata GD&T ntabwo ari impapuro, ahubwo ni ururimi rukora. Iyo igishushanyo cyerekana kwihanganira imyanya Ø0.05 mm ugereranije na datum axis, turagenzura iyo axe * mbere * gutunganya - ntabwo nyuma. Iyo kurangiza kurangiza bisaba Ra 0.4 µm mumaso yikidodo, dukoresha guhinduranya diyama-ntidusya - kuko gusya bitera kwangirika kwubutaka butangiza umunaniro munsi yikizunguruka.
Iyo minzani. Waba ukeneye umuvuduko wa prototype eshanu cyangwa 300 pompe ya pompe buri gihembwe, ibikorwa byacu bidafite aho bihuriye nigihe cyizuba, umusaruro wibintu, hamwe numusaruro wambere-utiriwe utanga kugenzura ibyuma.
Guhitamo umufasha-ntabwo ari ugutanga gusa-kubice bya nikel bishingiye kumashanyarazi
Uburenganzira nikel-ishingiye kuri alloy mashini yinganda ntabwo ihuye gusa na spes. Irateganya aho ibisobanuro bigufi. Irabizi ko imbaraga za AMS 5387 zigabanuka 12% mugihe igisubizo cyo gukemura kirenze 1180 ° C-nubwo MTR ivuga "murwego." Byunvikana ko umusenyi-T800 usaba ibipimo bitandukanye byo kurasa kuruta gushora imari-kuberako igabanywa ryimyitozo itandukanye.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikorera kuri iryo sangano ryibikoresho siyanse nubukorikori bwuzuye. Ntabwo tubitse ibintu rusange. Twebwe injeniyeri itunganya urutonde rwibikorwa byawe-ntabwo ubushobozi bwimashini yacu. Ikigo cyacu cyujuje ISO muri Qingdao gitanga cobalt-nikel yemewe muri Amerika ya Ruguru, Uburayi, no mu majyepfo y’amajyepfo ya Aziya - ntabwo ari ibintu byemewe, ahubwo ni ibisubizo byemewe.
Niba umushinga wawe utaha urimo umuvuduko mwinshi, ubushyuhe bwinshi, cyangwa kwambara cyane-kandi ukeneye ibice bikora nkuko byateguwe, guhinduranya nyuma yo kwimuka, umwaka ku wundi - tangira ukoresheje ibintu bifatika, ibipimo bifatika, hamwe no kwemeza-isi. Ntabwo ari udutabo. Ntabwo ari amasezerano. Icyemezo cyagaragaye.
