Iyo abajenjeri bagaragaje ibice bya pompe hydraulic, indangagaciro zo hanze, cyangwa sisitemu ya winch iremereye, ntibakenera gusa "ibyuma byakozwe." Bakeneye gutuza kurwego munsi ya 300 bar igitutu. Bakeneye cobalt alloy nozzles irwanya guhuha kuri 650 ° C. Bakeneye amazu yubatswe aho uburinganire bwa microstructure buhuye na GD&T guhamagarwa - kugeza kuri ± 0.01 mm. Niyo mpamvu abatanga OEM kwisi yose hamwe nabatanga Tier-1 bahora bagaruka kuri a uruganda rutunganya neza yashinze imizi ntabwo isaba ibicuruzwa - ahubwo ni uburyo bwo gusubiramo inzira, kugenzura ibyuma, no kugenzura zeru.
Kwihanganirana kwisi bisaba gutwara amahitamo nyayo yo gukora
Twabonye imishinga myinshi ihagaze kuri prototype-ntabwo bivuye mubishushanyo mbonera, ahubwo bivuye mubushobozi budahuye. Umukiriya yigeze kutwoherereza AMS 5387 ya piston pompe yo gushushanya amazu afite kwihanganira imyanya nyayo ya Ø0.015 mm kuri bore umunani zikomeye. Ababitanze mbere bavuze ko ari "CNC-imashini," hanyuma itanga ubufindo butatu bukurikiranye hamwe na 0,032 mm gutandukana kuruhande rwa kashe yinyuma. Kubera iki? Kuberako bari CNC'd batera umucanga ubusa nta kugabanya ububabare bwa mbere-kandi ntibapimye gutwarwa nubushyuhe mugihe cyamasaha menshi yo kurangiza. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata buri micron nkibisabwa bikora, ntabwo ari ibisobanuro byerekana ibisobanuro. Ikigo cyacu cyujuje ISO muri Qingdao gihuza casting, kuvura ubushyuhe, hamwe na 5-axis ikora munsi yinzu imwe - ntabwo byoroha, ahubwo gufunga mububiko bwibipimo byambukiranya imipaka. Iyo ukoresheje imashini ya T800 cobalt alloy plug nyuma yo gushora imari, guhangayika gusigaye ntabwo ari theoretical. Nicyo gihindura umurongo wawe wanyuma kuri 0.008 mm. Turabishushanya. Turaruhutse. Turabigenzura - mbere yo gukata bwa mbere.
Ntabwo amaduka yose "avanze cyane" akora superalloys kimwe
Bamwe mubakora urutonde "cobalt-nikel alloys" murutonde rwabo hanyuma bahagarare aho. Ariko uburambe buratubwira: AMS 5387 ntacyo yitwara nka Inconel 718 mugihe cyo gusya uruzitiro ruto. Igipimo cyacyo cyo gukomera cyiyongera nyuma ya 0,15 mm z'uburebure bwo gukata. Ubushyuhe bwumuriro ni kimwe cya kabiri cyibyuma bitagira umwanda - bityo ibikoresho byubuzima bigabanuka niba imvura ikonje igabanutse munsi ya 45 L / min saa 12,000 rpm. Dukoresha igenzura rya spindle yihariye kumashini yacu ya Mazak INTEGREX i-200S - ntabwo dukurikirana ibipimo byigihe, ahubwo tumenye uburyo bwo kuganira mikoro ibanziriza kwangirika kwubutaka. Nuburyo dufata Ra ≤ 0.4 µm kumurambararo wimbere wintebe ya cobalt alloy valve, ndetse no kuri mm 120 z'uburebure-kuri diameter. Kandi yego - twemeza buri kintu cyose kurwanya ingano ya ASTM E112, kubisabwa nabakiriya. Nta bitekerezo. Nta bigufi.
Kwishyira hamwe bihagaritse bisobanura amaboko make - kandi amanota make yo gutsindwa
Tekereza ku mubiri w'umuvuduko ukabije: ushyizwe mu cyuma cyangiza (ASTM A), gishyuha ubushyuhe bugera kuri 28-32 HRC, hanyuma ugakorerwa hamwe na sisitemu esheshatu zifunze, ibyambu bine bifatanye, hamwe na bore ebyiri zifata imashini - byose biri muri ± 0.012 mm byuzuye. Niba gutara, gutunganya ubushyuhe, no gutunganya bibaye kubacuruzi batandukanye, ninde ufite ikosa rya stack-up mugihe inteko ya nyuma yamenetse kuri 250 bar? Kuri QINGDAO QIANGSENYUAN, itsinda rimwe ryubwubatsi rigenzura uko byakurikiranye. Uruganda rwacu rukoresha verisiyo yo kugenzura mbere yo gusuka. Amashyiga yacu yubushyuhe bwo gutondekanya igihe-ubushyuhe bwa profili kuri buri mutwaro-ntabwo kuri buri mwanya. Laboratwari yacu ya CMM ikoresha ASME B89.1.10M ikurikiza kalibrasi ya buri munsi, kandi buri gice kibona igenzura ryuzuye rya geometrike - ntabwo ari ugusuzuma gusa. Gukurikirana ntabwo ari raporo; ni QR code yashyizwe muri buri kintu gihuza gusubira muri chimie yashonze, indangamuntu yikizamini, hamwe nuwabisinyiye yasuzumye ubugenzuzi bwa nyuma.
Nuburyo ibice byingenzi byubutumwa byizerana-ntabwo ari ugutanga gusa
Abakiriya bacu ntabwo baduhitamo kubiciro byo hasi. Baraduhitamo kuko mugihe pompe yu Burayi OEM yari ikeneye amazu 47 adasanzwe ya silinderi kugirango ikoreshwe mu kizamini cyo mu nyanja - kandi isaba ibyemezo byuzuye, raporo za NDT, hamwe namakuru yo gupima imikorere mugihe cyiminsi 18 - bari bazi gusiba "igishushanyo mbonera cyo gukora" bizatwara amafaranga arenze ayo yatanzwe. Twakoresheje rero GD&T kwemeza mbere yo gusubiramo. Amabendera abiri yihanganira kutabangikanya nibikoresho bisanzwe. Yasabye gahunda ya datum ivuguruye ifite imikorere mugihe igabanya igihe cyikigereranyo cya 22%. Yatanzwe kuri gahunda-hamwe na buri gipimo cyemejwe, buri buso burangije kugenzurwa, hamwe nubushyuhe bwo kuvura umurongo wabitswe. Ngiyo injyana ikora yukuri uruganda rutunganya neza: inama tekinike yubatswe mubikorwa, ntabwo yongeweho nkibitekerezo.
Urebye imbere, icyifuzo ntabwo ari "gutunganya byinshi" - ni kubikorwa byubwenge buke. Gushora imari hiyongereyeho gucukumbura neza EDM kumiyoboro ikonjesha mumashanyarazi yumuvuduko mwinshi. Gutera umucanga hamwe na thermocouples yashizwemo ikarita ikomera mugihe nyacyo. R&D ntabwo ikururwa hano-yapimwe mubipimo byagabanutse, indangagaciro za Cpk zikomeye kubiranga ibintu bikomeye, hamwe nubushobozi bwihuse bwihuse kubintu bishya byo mu kirere. Niba umushinga wawe utaha ushingiye kubisubiramo - ntabwo ari imvugo - tangirana no gukorera mu mucyo, ntabwo ari amasezerano yagatabo. Ibice ntibizabeshya. Natwe ntitubikora.
