Mafakitole amakono opangira zitsulo za ufa samangopanikizira ufa wachitsulo—amapanga ma microstructures. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Tawona momwe kupita patsogolo kwa ntchito za fakitale ya ufa zitsulo zimasinthira mwachindunji magwiridwe antchito pamapampu a hayidiroliki, mavavu apamwamba kwambiri, ndi ma nozzles aloyi a cobalt. Kutumiza kwapadziko lonse lapansi - osati chiphunzitso cha labu - kumayendetsa kukweza kwathu. Pamene kasitomala AMS 5387 cobalt aloyi mpope nyumba analephera kukhazikika dimensional pambuyo mankhwala kutentha, sitinawalondole ku kusagwirizana kwa zinthu, koma kulamulira kwachikale sintering atmosphere. Chochitika chimenecho chinayambitsa kuunikanso kwathunthu kwa makina athu opangira matenthedwe. Masiku ano, "kupita patsogolo kwa fakitale ya zitsulo zopangira zitsulo" kumatanthauza kulolerana kolimba, kachulukidwe kachulukidwe kachulukidwe kambiri, ndi kucheperako kwa makina a post-sinter-osati nthawi zozungulira mwachangu.
Kulondola Kumayamba Kusanakhazikike
Mainjiniya ambiri amaganiza kuti kulondola kwazitsulo za ufa kumatengera kapangidwe ka kufa kapena kusindikiza matani. M'malo mwake, zimayamba ndi kukonza zinthu zakuthupi. Tsopano timayang'anitsitsa ufa wonse wa T800 ndi cobalt-nickel pogwiritsa ntchito laser diffraction ndi SEM morphology mapu-osati kusanthula kwa sieve. Chifukwa chiyani? Chifukwa kusiyanasiyana kwa 5% mu particle sphericity kumasintha kachulukidwe wobiriwira mpaka 0.12 g/cm³ kudutsa ma geometri ovuta ngati ma silinda a pampu ya piston. Dongosolo lathu lazakudya lomwe lasinthidwa limagwiritsa ntchito metering yogwedezeka ndi mayankho a nthawi yeniyeni, kudula kachulukidwe wa batch-to-batch kuchoka pa ±0.08 g/cm³ mpaka ±0.03 g/cm³. Kusintha kwakung'ono kumeneko kumachotsa 70% ya gawo loyamba la CMM rework pa matupi olimba a valve. Tidasinthanso kuchokera ku nayitrogeni-okha kupita ku gasi wapawiri (N₂ + H₂) woyimitsa mpweya wa cobalt alloys-kuchepetsa zotsalira za okusayidi ndi 92% ndikupangitsa kuti Ra 0.8 µm ikhale yomaliza popanda kugaya kachiwiri.
Kupanga Zophatikiza Kumatseka Kusiyana Pakati pa Kuponya ndi Machining
Ena anganene kuti zitsulo za ufa sizingafanane ndi kuponyedwa kwa ndalama kwa ndime zamkati. Koma izo ndi zakale. Kutsogola kwathu kwaposachedwa kumaphatikiza kuphatikizika kwa PM kofanana ndi net-net ndi zoyika zida zopangidwa ndi makina a CNC-kutilola kuti tiyike mayendedwe ozizirira, matumba amipando ya ma valve, ndi ma grooves othandizira ulusi * mu compact yobiriwira* tisanayime. Kwa ma roller a winch center shaft omwe amagwiritsidwa ntchito m'magalimoto a engineering, izi zidachepetsa nthawi yotsogolera ndi 40% ndikudula zinyalala zakuthupi ndi 65%. Chofunikira kwambiri, njirayi imateteza kulumikizika kwambewu m'madera ovuta kwambiri: mphamvu zolimba pazitsulo zonyamula katundu zimakhala mkati mwa ± 2% ya ndondomeko, ngakhale 120 mm m'mimba mwake ndi 2.8 kg kulemera. Timatsimikizira gawo lililonse la haibridi ndi mapu akupanga makulidwe a pre- ndi post-sinter-palibe zongoganiza, zoyezera deta yokha.
Kutsatiridwa Sikutsatiridwa—Ndiko Kulamulira Molosera
ISO 9001 imafuna kufufuza. Zomwe sizimalamula - komanso zomwe makasitomala athu amafunikira - ndikulosera zam'tsogolo. Gulu lililonse la ufa wa AMS 5387 limanyamula pasipoti yachitsulo yolumikizidwa ndi QR: ma curve a kukula kwa tinthu, zipika za okosijeni, ndi ma signature a sintering thermograph. Makasitomala akamanena kuti zavala zocheperako pa pulagi ya cobalt alloy, timakoka pasipotiyo ndikuyilozera patali ndi zipika zowongolera ng'anjo kuyambira sabata lomwelo. Kota yatha, izi zidawonetsa kugwedezeka kosawoneka bwino kwa masensa a mame - zomwe zidapangitsa kuti ma carbide am'deralo akuwuke mu 3.2% ya magawo. Tinaigwira isanatumizidwe. Kufufuza kwathunthu sikukhudza zolemba; ndi za kudzipatula chifukwa chake mkati mwa mphindi 90. Kutha kumeneku kumafunika kwambiri pazinthu zomwe sizili wamba pomwe geometry ndi ntchito sizingasiyanitsidwe.
Chotsatira ndi Chiyani? Osati Ufa Wabwinoko—Kuphatikizana Mwanzeru
Kupita patsogolo kwamafakitale opangira zitsulo zamafuta sikuchokera ku makina osindikizira akuluakulu kapena ma conveyors othamanga. Adzabwera kuchokera kuphatikiziro lolimba pakati pa sayansi yazinthu, mafanizidwe amafuta, ndi kuyesa kogwira ntchito. Pakalipano, tikulowetsa ma geji amagetsi muzitsulo za sintering kuti tigwirizane ndi kuchuluka kwa kutentha ndi kusokoneza komaliza pa maziko a pampu. Tikutsimikiziranso mitundu yamapasa ya digito motsutsana ndi ma scans enieni a CMM a 120+ sintered iron castings — ma algorithms ophunzitsira kuneneratu za warpage asanayambe kugunda koyamba. Izi si zoyeserera za R&D. Ndi zida zopangira zomwe zatulutsidwa kudera lathu lonse la Qingdao chaka chino. Kwa makasitomala omwe amapeza zida zachitsulo zolondola, izi zikutanthauza kuti zosintha zauinjiniya zocheperako, zokolola zambiri, komanso kutsimikizika kotsimikizika—osati kusindikiza kokha, komanso moyo wautumiki. Tsogolo la metallurgy ufa sizinthu zowuma. Ndi magawo omwe amadziwa malire awo asanachoke kufakitale.
