Iyo sisitemu ya hydraulic yananiwe munsi yumuvuduko wa bar-350, cyangwa cobalt-alloy pump nozzle yamenetse nyuma yamasaha 47 yo gukomeza gukora, ikibazo gake gishingiye mubishushanyo. Ituye muri ibice bitunganijwe neza ibyo byahinduye ibyo bishushanyo mubyukuri bifatika - aho microns itandukanya imikorere no gutsindwa.
Twabibonye ubwacu: OEM yo muri Amerika y'Amajyaruguru yanze ibintu bitatu bikurikiranye amazu ya pompe ya piston ya AMS 5387 - atari ukubera ko basaga nabi, ariko kubera ko amakuru ya CMM yerekanaga 0,012 mm ya axial yiruka ku ntebe. Ibyo ntibiri munsi yubugari bwimisatsi yumuntu. Nyamara uko gutandukana kwateje kashe imburagihe no kugaruka kumurima. Igikosorwa nticyari gisubiye inyuma - cyakomezaga kugenzura uburyo buturuka ku isoko: ibintu bifatika bikurikirana, guhagarika ubushyuhe mbere yo gutunganywa bwa nyuma, hamwe nigikoresho nyacyo cyo kwambara indishyi ku ruganda 5-axis. Ibyo ntabwo ari ugukora. Iyo ni disipuline yo mu rwego.
Kuki alloy complexe isaba guhuza vertical-ntabwo ubushobozi bwa CNC gusa
Amavuta ya Cobalt-nikel nka T800 na AMS 5387 ntabwo yitwara nka aluminium 6061. Bakora-bikabije, bitwara ubushyuhe nabi, kandi bagasaba ibipimo byihariye byo kugabanya - kumanuka ugana icyerekezo no gukonjesha. Amaduka akora gusa CNC gutunganya akenshi asohora casting, hanyuma akarwana no kugoreka imihangayiko isigaye mugihe cyo kurangiza. Twapimye mm 0.08 mm y'intambara mumazu ya CoCr yatewe umucanga nyuma yo gukora imashini yonyine-bihagije kugirango dusibe igice cya $ 2,400.
Igisubizo ntabwo imashini yihuta. Igenzurwa nintera hagati yimikorere:
- Gukoresha imashini: Gushyushya gahunda yo kuvura ifunze kumibare myinshi - ntabwo amatariki ya kalendari
- Gukomeza imashini: Ubusugire bwubuso bwabitswe wirinda gukemura kabiri; nta kongera guhuza hagati yo guhinduka, gusya, no gusya
- Urunigi rwibikoresho: Buri fagitire mbisi itwara raporo yikizamini cyuzuye (ASTM E112 ingano, ingano ya ASTM E1268) ihujwe nindangamuntu yarangiye
Niyo mpamvu "ibice bitunganyirizwamo uruganda" bisobanura ikintu gitandukanye mugihe cyo gutara, gutunganya, no kwemeza ibyuma bibera munsi yinzu imwe - hamwe na sisitemu imwe.
Aho GD&T ihagaritse kuba theoretical-hanyuma igatangira gutegeka akazi
Abakiriya batwoherereza ibishushanyo hamwe no kwihanganira imyanya ± 0.005 mm kuri Ø12 mm bores, utitaye ko ibiranga bicaye muri mm 300 ya firime cyangwa 45 mm ya cobalt. Amaduka amwe afata GD&T nkurutonde. Turabifata nk'ikarita yo kubyaza umusaruro.
Kurugero: idasanzwe ya winch center shaft roller hamwe na bores eshatu coaxial, buri kimwe gisabwa icyarimwe kugenzura imyanya ugereranije nindege ya datum yakozwe 200 mm kure. Imyitozo isanzwe? Banza ukoreshe datum, hanyuma uzenguruke igice hanyuma wongere ushireho umurongo. Ariko gutwarwa nubushyuhe hagati yimikorere bizana kwibeshya. Igisubizo cyacu: gushiraho rimwe-5-gutunganya imashini ukoresheje vacuum igikoresho cyihariye gifata hejuru ya datum hamwe nibizunguruka-byagenzuwe na laser tracker mbere yuko gukata gutangira.
Ibyo ntabwo birenze urugero. Ni ugukuraho isoko nini yo gutandukana: ibisobanuro byabantu kubihanganira.
Gukurikirana ushobora kugenzura - ntabwo bisaba gusa
"Full traceability" igaragara kurubuga rwa buriwese utanga isoko. Niki gitandukanya irangizwa ryizewe na kopi yo kwamamaza?
Mubikoresho byacu byubahiriza ISO, gukurikirana bitangirana no gushonga - ntabwo byateganijwe. Buri cyiciro cya cobalt alloy batwara:
- Indangamuntu idasanzwe ifitanye isano nisesengura ryimiti (ICP-OES yagenzuwe)
- Amafoto yimiterere yintete kuva ibice birebire
- Ikarita ishushanya hejuru ya bilet yambukiranya igice (ntabwo ari ugusoma gusa)
- Isano riri hagati yamakuru yo kuvura ubushyuhe hamwe na microhardness ya nyuma kuri zone zikomeye
Mugihe uruganda rukora pompe rwiburayi rwasabye ibisekuru byuzuye kumubiri umwe wa AMS 5387, twatanze impapuro 17-zirimo ibishushanyo mbonera byamateka yubushyuhe, imirongo yikizamini cya tensile, na raporo yubugenzuzi bwa CMM yerekeranye nisaha. Nta kwiyubaka. Nta kigereranyo. Gusa ububiko bwamakuru, bwagaruwe muminota 90.
Urwo rwego rwinyandiko ntirubaho rudafite gahunda yimikorere ya digitale-kandi utiriwe ufata buri kintu nkibikorwa byingenzi, ndetse no muri prototype ikora.
Ibyukuri-byukuri ntabwo ari ugukubita zeru-ni ukugenzura itandukaniro
Ubusobanuro nyabwo ntabwo busobanurwa nigipimo kimwe. Nukwitandukanya gutandukana mubice 500, mugihe cyibyumweru bitatu byumusaruro, mubikorwa bibiri bitandukanye. Dukurikirana indangagaciro za CpK-ntabwo zitambutse / gutsindwa gusa-kuri buri kintu gikomeye kuri buri kintu cyihanganirwa cyane. Intego yacu? CpK ≥ 1.67 kubintu byose aho imikorere ikora biterwa na geometrike.
Iyo disipuline ituma dushyigikira abakiriya bakeneye ibirenze ibice - bakeneye guhanura. Yaba ifashe mm 0.008 mm ku cyicaro cyumuvuduko wa kashe ifunga akabari 420, cyangwa kugumana ubukana bwa Ra ≤ 0.4 µm ku muhogo wa cobalt nozzle igenga umuvuduko ukabije, intego ikomeza kuba imwe: gukuraho ukutamenya gushidikanya mbere yuko igera mu murima.
Niba porogaramu yawe isaba guhagarikwa kugarukira murwego rwo hejuru-kandi niba "hafi bihagije" bishobora guhura nigihe gito, impanuka z'umutekano, cyangwa garanti-noneho uburenganzira ibice bitunganijwe neza ntabwo arimwe hamwe nimashini nshya. Nicyo gipima aho kigarukira, cyandika buri gihindagurika, kandi gifata kwihanganira nkimbogamizi nzima-ntabwo ari imibare ihamye ku icapiro.
