Nthawi zonse tikamatsegula chitseko cha ng'anjo mufakitale yopangira zitsulo za ufa, timayang'ana zinthu zitatu poyamba: milingo ya okosijeni, kuchuluka kwa fumbi, ndi kupitiliza kwa nthaka. Osati chifukwa zili pamndandanda - koma chifukwa tidawonapo fungo lokhazikika likuyaka mtambo wafumbi wa titaniyamu pakusintha kwanthawi zonse. Zomwe zidachitikazi zidasinthanso momwe QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imaphunzitsa ogwira nawo ntchito, imayang'ana makina ake a mpweya wabwino, ndikutsimikizira gulu lililonse la AMS 5387 cobalt ufa lisanakhudze atolankhani. Chitetezo pamafakitale opangira zitsulo zamafuta sichimayikidwa pamwamba pakupanga - chimapangidwa mu geometry ya kufa, nthawi ya kuyeretsa, ndi chipika chotsatira chomwe chimatsatira nyumba iliyonse ya piston pampu kuchokera ku ufa mpaka lipoti lomaliza la CMM.
Fumbi lachitsulo loyaka moto ndi limene limayang'anira mbali ya ngoziyo, osati utsi, osati kutentha, koma tinthu ting'onoting'ono tomwe timatulutsa mpweya. Aluminiyamu, titaniyamu, kasakaniza wa faifi tambala, ngakhalenso zitsulo zosapanga dzimbiri zimakhala ngati mafuta pamene tinthu tating'onoting'ono titsika pansi pa ma microns 100 ndi mpweya woposa 12%. Malo athu ku Qingdao amakhala ndi mpweya wochepera 8% mkati mwa ng'anjo za inert-gasi pogwiritsa ntchito masensa a paramagnetic anthawi yeniyeni, osati zowerengera nthawi kapena kuyerekezera. Timawawerengera sabata iliyonse. Timalemba kupatuka kulikonse. Ndipo ngati mpweya umalowa pamwamba pa 9.5% kwa masekondi opitilira 45, makinawo amazimitsa okha ndi nayitrogeni ndikutseka chitseko chotsegula mpaka atakhazikitsanso pamanja ndi woyang'anira chitetezo. Izi sizowonjezera-injiniya. Ndizomwe zimalepheretsa ma nozzles a cobalt-nickel kukhala magwero oyatsira m'malo mwa zida zowongolera.
Kuwongolera fumbi kumayamba ufa usanalowe mnyumbamo. Timakana mafuta aliwonse omwe akubwera a T800 alloy powder popanda zolemba zonse za SDS, kagawo kakang'ono kagawidwe ka tinthu (D50 ≤ 42 µm), ndi chinyezi <0.05%-yotsimikiziridwa ndi Karl Fischer titration atalandira. Pogwira ntchito amagwiritsa ntchito mizere yosindikizidwa yosindikizidwa yokhala ndi mpweya wabwino wa nayitrogeni, osati ma scoops kapena ma funnels. Ng'oma iliyonse yophatikiza imazungulira mkati mwa bokosi la glove lomwe latsekedwa <1% O2. Oyendetsa amavala nsapato zoyeserera zoyesedwa tsiku lililonse; matailosi pansi amayikidwa pa 106 ohms resistance max. Tikamaliza kupanga zitsulo kapena mapulagi a cobalt-alloy, timagwiritsa ntchito makina oziziritsa-osati madzi osefukira - kupeŵa chindapusa chotsalira chotsekeredwa mu micro-porosity. Makasitomala adafunsapo chifukwa chake magawo athu a pampu a AMS 5387 amawononga 7% kuposa njira zina zakunyanja. Tidawawonetsa zolemba zathu zoyeserera zophulika za fumbi - ndi mndandanda wa 14-point pre-shift checklist aliyense wogwiritsa ntchito asanagwire atolankhani.
Zinthu zaumunthu ndizofunikira kwambiri monga hardware. Tidapeza kuti 68% ya zomwe zidatsala pang'ono kuphonya mufakitale yathu yopangira zitsulo zamafuta zidachitika panthawi yopereka zinthu kapena pambuyo pokonzanso -nthawi yomwe kusamala kumatsika. Chifukwa chake tidakonzanso njira yathu yotsekera-tagout (LOTO): ng'anjo zonse za sintering tsopano zimafuna kutsimikizira kawiri-katswiri wina amatsimikizira kudzipatula kwa gasi, wina amatsimikizira kutulutsa mphamvu kwamagetsi - hatch isanatseguke. Tidasintha zilolezo zamapepala ndikuyika makina a digito opangidwa ndi piritsi omwe amakakamiza kujambulidwa kwazithunzi za kukhulupirika kwa fyuluta, kukangana kwa lamba, ndi kupitilira kwa waya wokhazikika tisanalole zida kuyambiranso. Palibe kuchotserapo. Palibe zowonjezera. Ndipo ganyu iliyonse yatsopano imathera maola awo 48 oyambirira osati pa siteshoni ya CNC, koma kubisa chiwongolero chathu chachitetezo chamkati mkati mwa zitsanzo za ufa, kuyeretsa sieve, ndi kubowola kwadzidzidzi kwa nayitrogeni.
Ma protocol achitetezo m'mafakitole a ufa zitsulo amagwira ntchito pokhapokha ngati sasiyanitsidwa ndiukadaulo. Simungalekanitse "chitetezo" kuchokera ku GD&T kutsimikizika, nthawi yothira kutentha, kapena kuuma kwapamwamba - chifukwa porosity imakhudza kusungidwa kwafumbi, kuuma kumakhudza kuwopsa kwa spark, ndi kugwedezeka kwamphamvu mu valavu yokakamiza kumasintha khalidwe losindikiza pansi pa njinga yamoto. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD., lipoti lililonse loyendera limakhala ndi njira zonse zogwirira ntchito/zolephera *ndi* metadata yofunika kwambiri pachitetezo: ID ya powder lot, sintering atmosphere log, nthawi yowotcha ma hydrogen, ndi makulidwe a okusayidi pamwamba poyezera kudzera pa XPS. Zomwezo sizimangokhutiritsa ISO 9001. Imatiuza ngati mphuno ya aloyi ya cobalt idzapulumuka mizunguliro 10,000 mu manifold high-pressure hydraulic-kapena kukhala pobisalira poyatsira. Tsogolo liri la opanga omwe amawona chitetezo osati ngati kutsata pamutu, koma ngati gawo loyamba la kulondola. Chifukwa mu ntchito za fakitale ya ufa, kulolerana sikungokhudza ma microns-komanso malire pakati pa kuwongolera ndi zotsatira zake.
