Iyo abajenjeri bagaragaje igice kigomba kwihanganira ± 0,02 mm kwihanganira, kurokoka 400 ° C gusiganwa ku magare, no kurwanya isuri biturutse ku gutemba-nta mwanya wo guta ibitekerezo. Aho niho an uruganda rushora imari hamwe na disipuline yemejwe yerekana itandukaniro hagati yo gutsindwa kumurima nubuzima bwimyaka 15. Twabibonye imbonankubone: inzu ya pompe hydraulic yamenetse kuri 8000 psi mugihe cyo kwemezwa-bitatewe nigishushanyo mbonera, ariko kubera ko microstructure ya-cast yarimo kugabanuka kutamenyekanye hafi yintebe ya valve. Gukosora ntibyari gusubiramo. Byari guhindukirira umufatanyabikorwa ugenzura ibishishwa bya chimie, ibishishwa byumye, hamwe nigipimo cya dewaxing - ntabwo ari "ibice byo guta" gusa, ahubwo nibikorwa bya injeniyeri.
Icyitonderwa gitangira mbere yisuka rya mbere
Igishoro nyacyo cyo gutera neza ntigishobora kugerwaho mu itanura. Itangirana nibintu bifatika kandi bigasubirwamo. Ku kigo cyacu cyujuje ISO muri Qingdao, buri cyiciro cya cobalt-nikel alloy gitwara ibyangombwa byose byemejwe nubushyuhe-uhereye kubisesenguye mbuto (AMS 5387, ASTM F75) kugeza ibisubizo byanyuma-ibisubizo byimbitse. Ntabwo twemera chimie "isanzwe". Tugenzura chromium, molybdenum, hamwe na karubone mbere yo gusuka - hanyuma tukandika buri kintu cyose: ubushyuhe bwigikonoshwa, igihe cyo gutura, igihe cyo kumara igihe cyo kumara, hamwe n umuvuduko wa vacuum. Kubera iki? Kuberako gutandukana kwa 2 ° C muburyo bwubushyuhe buhindura igipimo cyo gukomera bihagije kugirango uhindure ingano ya karbide ikwirakwizwa muri superalloys yo mu rwego rwa T800. Ibyo bigira ingaruka zokunanira umunaniro munzu ya piston pompe ya silinderi munsi yikizunguruka.
Twabyemeje muri 127 ikora ya AMS 5387 cobalt alloy ibice 6 bya pompe. Ibice byashyizwe munsi yubugenzuzi byerekanaga 31% hejuru yubuzima buke bwumunaniro hamwe na geometrie imwe ikoresheje iguriro rusange. Itandukaniro ntabwo ryakoraga-ni ugukina ubwabyo.
Kwishyira hamwe Vertical Ntabwo ari Buzzword-Nubwishingizi bwa Dimensional
Bamwe mubatanga isoko barangiza. Abandi bafata casting na CNC nk'amashami atandukanye. Turabahuza. Uruganda rwacu rwishoramari rukora ibintu byose: guhimba ibishishwa bya ceramic, gutondeka neza, kugabanya ubushyuhe bwo kugabanya ubushyuhe, gutunganya imashini nyinshi za CNC (harimo 5-axis ihuza inzira yimbere yimbere), hamwe nubuvuzi bukora nka HVOF tungsten carbide coating. Ibi bivanaho interineti ihuza ibipimo - ubwoko buhindura GD & T-bwerekanwe 0.015 mm kwihanganira imyanya ihinduka 0,032 mm nyuma yo gukuramo gatatu.
- Umuvuduko wumuvuduko wakozwe muburyo butaziguye - nta bikoresho bya kabiri bisabwa
- Pompe fondasiyo hamwe na flanging ya flanges hamwe nibyambu byamazi, byose bifatiye kuri ASME B16.34 kwihanganira ibyiciro 600
- Ubwubatsi bwikinyabiziga winch center shaft izunguruka hamwe no kwambara hejuru yimyambarire hamwe nuburinganire bwubutaka butagenzuwe
Iyo OEM yu Burayi yari ikeneye gusimbuza cobalt alloy nozzles kuri sisitemu yo kumanuka umuvuduko ukabije, uwabitanze mbere yabanje gutanga ibice bisaba kongera gukora 100% kugirango byuzuze ibitekerezo. Twatanze ibice byambere bikora-kuberako gahunda yacu ya CNC isoma mu buryo butaziguye uhereye kuri CT scan data, ntabwo ari moderi ya CAD yerekana.
Igenzura ryiza rikora, ntabwo ryanditse gusa
"Kugenzura" ntacyo bivuze niba bibaye kumpera gusa. Sisitemu yacu yubuziranenge ikubiyemo igenzura kuri bariyeri enye zidashobora kuganirwaho: ibyemezo byinjira byinjira, murwego rwo gupima CMM nyuma yo gutunganywa gukabije, profilometrike optique hejuru yikimenyetso gikomeye, hamwe no gupima imikorere ya nyuma - harimo no kugenzura kwangirika kwumuvuduko wa 1.5 ×. Igice cyose kibona indangamuntu yihariye ihujwe na sisitemu yuzuye ya digitale: isesengura ryerekana ibintu byashonga, amateka yubushyuhe bwo gutondeka, guhuza raporo ya metrologiya, hamwe nikarita yerekana ububi.
Twagize abakiriya babaza bati: "Urashobora kwemeza ko zeru zeru muri zone ya valve?" Igisubizo ni oya - twemeza gutahura. Niba scan ya ultrasonic yerekana ibimenyetso byose birenze ASTM E1815 Urwego rwa 2, dusiba igice. Nta na kimwe kidasanzwe. Iyo disipuline yatumye igipimo cya PPM kiri munsi ya 187 kubice bikomeye bya hydraulic yibikorwa mumezi 37 ashize.
Gutanga-Kwisi-Ntabwo byasezeranijwe gusa ibihe byo kuyobora
Igihe cyambere cyo gusezerana gisobanura bike mugihe gahunda ya prototype ihagaze iminsi 11 utegereje ibyemezo bifatika. Twabitse AMS 5387, F75, hamwe nicyuma 17-4PH mubyuma byinshi - hamwe na raporo yikizamini cyuzuye kuri dosiye. Kubikorwa byihutirwa, turashobora gutangira guhimba shell mugihe cyamasaha 48 yo kwemeza. Ibikorwa byacu bidafite ishingiro bikurikirana WIP binyuze mu bimenyetso bya Kanban - ntabwo ari urupapuro rwerekana - kandi impuzandengo yacu yo kugemura ku gihe cyo gutumiza ibicuruzwa bito (50-500 pcs) bihagaze kuri 98.4%, bigenzurwa n’ubugenzuzi bw’ibikoresho bya gatatu muri Amerika y'Amajyaruguru no kohereza ibicuruzwa mu Burayi.
Uruganda rumwe rukora pompe yo mu majyepfo y’iburasirazuba bwa Aziya rwagabanije igiciro cy’ubutaka ku gipimo cya 22% nyuma yo kuduhindukira - atari ukubera ko igiciro cyacu cyagabanutse, ariko kubera ko bakuyeho ibintu bitatu byo kugenzura, bagabanya ibicuruzwa bivuye kuri 14% bikagera kuri 0.9%, kandi bunguka ibitekerezo-byakozwe mbere yo kwiyemeza.
An uruganda rushora imari yizera ikizere atari udutabo, ariko hamwe na microstructures isubirwamo, yanditse amateka yubushyuhe, hamwe nuburinganire buringaniye kumuzingo 10,000. Ibice by'icyuma neza ntibyihanganira kudasobanuka. Natwe ntitubikora. Niba igice cyawe gikurikira gisaba ibirenze kwihanganira izina-niba bigomba gukora aho gutsindwa atari amahitamo-tangirana na casting, ntabwo ari gahunda yo kugura.
