Iyo ba injeniyeri bagaragaje a uruganda rukora imashini, ntabwo batumiza ibice gusa-barinda umutekano muke munsi yumuvuduko wa hydraulic 350, barwanya gutombora muri cobalt-alloy nozzles kuri 650 ° C, cyangwa bakemeza ko microstructure ikomeza hejuru yinzu ya pompe yumucanga izakora amasaha 20.000 nta gutsindwa. Nibyo byukuri bikora-ntabwo isezerano ryamakuru.
Twabonye abakiriya bohereza ibishushanyo bya AMS 5387 cobalt alloy pump ibice gusa kugirango bakire ibice bifite ububobere buke munsi yo kuvura ubushyuhe. Abandi bakeka ko "CNC yakozwe" bisobanura "kwitegura gushiraho" - kugeza igihe T800 alloy center ya shaft roller yananiwe kwipimisha kunyeganyega kubera guhangayikishwa no gusigara bitagenzuwe biturutse ku gusya kwa asimmetric. Izi ntabwo ari imanza. Nibisubizo bitaziguye byubushobozi bwacitsemo ibice: gutara bikozwe niduka rimwe, gutunganya bikabije kurindi, kurangiza gusya na kimwe cya gatatu - buri kimwe gifite ingamba zitandukanye zinzira, imicungire yumuriro, hamwe nubugenzuzi.
Kuki guhuza verticale bidahitamo kubikorwa-byuzuye-byuzuye akazi
Igenzura ryukuri ritangira mbere yuko chip ya mbere iguruka. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Icyemezo cyibikoresho fatizo ntabwo ari intambwe yimpapuro-ni umusingi. Igiceri cyose cya T800 cobalt gishingiye ku mavuta kigera hamwe na raporo yipimisha ryerekana umubare wubushyuhe, ibigize imiti byagenzuwe na ASTM E1086, nubunini bwimbuto byemejwe binyuze kuri ASTM E112. Ntabwo twemera chimie "isanzwe". Dukeneye ibyemezo byemewe bya AMS 5387-cyane cyane kubice byingenzi bya pompe aho itandukaniro rya chromium iri hejuru ya ± 0.3% itera kwangirika kwigihe kitaragera mubidukikije bya gaze.
Iyi disipuline irakomeza binyuze mubikorwa. Gutera umucanga no gushora imari bibera kurubuga-ntabwo biva hanze - bityo tugenzura igipimo cyibishushanyo mbonera, ibyuma bikomera, hamwe nigihe cyo guhungabana. Gutandukana kwa 2 ° C mubushyuhe bwububiko bihindura intera ya dendrite ku kigero cya 12%, bigira ingaruka kumashanyarazi nubuzima bwumunaniro mumazu ya pompe ya pompe. Ingirabuzimafatizo zacu za CNC noneho zikoresha igenzura rya CMM nyuma yo gutombora, kurangiza, no kurangiza - ntabwo ari ubugenzuzi bwa nyuma. Dupima ubushyuhe bwumuriro kuri mashini-axis buri minota 90 kuko kwaguka kwa mm 0.008 mumiturire ya spindle byahinduye kwibanda kurenza aho kwihanganira GD&T.
Aho gutunganya imashini isanzwe ikora-kandi ikora mubyukuri
Bamwe bashobora kuvuga ko iduka ryemewe na ISO 9001 rishobora gukoresha amavuta ya cobalt-nikel iyo ihabwa ibikoresho byiza. Ariko uburambe-bwisi buravuga inkuru itandukanye. Carbide isanzwe yinjiza kuvunika ako kanya kuri AMS 5387 ku gipimo cyo kugaburira hejuru ya 0,05 mm / rev. Dukoresha ibikoresho bya PCD hamwe na geometrike itari nziza, coolant yatanzwe kuri bar 120 binyuze mumiyoboro yimbere, hamwe nuburyo bwo guhuza n'imikorere igumaho imitwaro ya chip ihoraho - ndetse no hafi ya 3D imiterere nkimibiri ya valve ifite umuvuduko wa mm 4.2 hamwe nuburinganire bwa 0.025 mm.
Ubusugire bwubuso bufite akamaro nka geometrie. Indorerwamo-kurangiza Ra 0.2 µm ntizarinda guhangayikishwa no kwangirika kwangirika niba microcracks zo munsi y'ubutaka zibaho kuva guhitamo gusya nabi. Kubyuma bidafite ingese bikoreshwa mumfatiro za pompe zo hanze, dukoresha amashanyarazi * nyuma yo * kurasa - atari mbere - kugirango tubungabunge imihangayiko isigaye mugihe tugera kuri ASTM A967. Uru ruhererekane ntabwo ari theoretical. Byemejwe kumasoko nyirizina, hamwe na SEM isesengura ryemeza ko hatabayeho gushingwa kwera.
Icyo "gakondo" bivuze mubyukuri mubikorwa byingenzi
Custom ntabwo yerekeye ibipimo bitari bisanzwe byonyine. Byerekeranye no guhuza imikorere. Mugihe OEM yu Burayi yari ikeneye imashini ya shitingi ya shitingi yimodoka ya arctique yo mu rwego rwa arctique, bagaragaje ubukana-ariko ntibabaze ubukana bwubushyuhe buke. Twakoresheje ibizamini bya Charpy V-notch kuri -40 ° C kubintu bitatu bivura ubushyuhe, dusaba ko hahindurwa ubushyuhe, kandi tugatanga imizingo ifite ingufu za 42 J (ntabwo ari 27 J isabwa gusa). Icyo cyemezo cyarinze kuvunika gucika mugihe gitunguranye umutwaro uhindutse kubutaka bwuzuyemo urubura.
Uru rwego rwubufatanye rugera ku gishushanyo-cyo-gukora. Dushyize ahagaragara GD&T guhamagarwa bivuguruzanya no gutoranya inguni. Twigana kugoreka ubushyuhe mumashanyarazi ya cobalt alloy nozzles mugihe cyo gukemura. Dutanga ibitekerezo byubaka mugihe cyamasaha 48 - ntabwo ari ibyumweru - kuko prototype itinda caskade mugihe cyo kwemeza umurima. Abashinzwe imishinga bavuga neza ASME Y14.5, ntabwo bavuga icyongereza gusa.
Niba ukeneye a uruganda rukora imashini ifata metallurgie nkubuhanga-ntabwo itanga amasoko-urashaka guhuza gukomeye hagati yubumenyi bwibintu, gutunganya amashyuza, no kugenzura neza neza. Ukeneye inyandiko zerekana kuva kuri numero yubushyuhe kugeza raporo yanyuma yo kugenzura. Ukeneye abafatanyabikorwa bakemuye T800 alloy plug wicaye kumurongo wa torque hejuru ya 17 hydraulic sisitemu. Ukeneye irangizwa ryagaragaye - ntabwo ari amagambo yubushobozi gusa. Ngiyo imbago aho ibisobanuro birangirira kandi imikorere itangirira.
