Pamene mainjiniya amatchula a mwambo aloyi Machining fakitale, sikuti amangoyitanitsa magawo - akuteteza kukhazikika kwamphamvu pansi pa 350 bar hydraulic pressure, kukana kuphulika mu nozzles ya cobalt-alloy pa 650 ° C, kapena kutsimikizira kupitiriza kwa microstructure kudutsa mchenga woponyera mpope nyumba yomwe idzayenda maola 20,000 popanda kulephera. Ndicho chenicheni cha ntchito-osati lonjezo lachidziwitso.
Tawona makasitomala akutumiza zojambula za AMS 5387 cobalt alloy pampu zigawo kuti alandire mbali ndi subsurface porosity pambuyo kutentha kutentha. Ena amaganiza kuti "CNC machined" amatanthauza "okonzeka kuyika" - mpaka cholozera chawo cha T800 alloy center shaft chikalephera kuyesa kugwedezeka chifukwa cha kupsinjika kosalamulirika kotsalira kuchokera ku ma asymmetric mphero. Izi siziri zochitika zenizeni. Ndiwo zotsatira zachindunji za luso logawanika: kuponyedwa kochitidwa ndi sitolo imodzi, makina okhwima ndi ena, kumaliza kugaya ndi gawo limodzi lachitatu-iliyonse ili ndi njira zosiyanasiyana, kasamalidwe ka kutentha, ndi njira zoyendera.
Chifukwa chiyani kuphatikiza koyima sikuli kosankha kuti mugwire ntchito yolondola kwambiri
Kuwongolera kowona kumayamba chip choyamba chisanawuluke. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., certification yaiwisi si gawo lazolemba-ndi maziko. Koyilo iliyonse ya T800 cobalt-based alloy imafika ndi malipoti oyesa mphero omwe amatsatiridwa ndi kuchuluka kwa kutentha, kapangidwe kake kakatsimikiziridwa motsutsana ndi ASTM E1086, ndi kukula kwambewu kumatsimikiziridwa kudzera pa ASTM E112. Sitivomereza chemistry "yofanana". Timafunikira kutsata kovomerezeka kwa AMS 5387—makamaka pazigawo zofunika kwambiri za mpope pomwe kusiyana kwa chromium pamwamba pa ± 0.3% kumayambitsa dzimbiri msanga wa intergranular m'malo a mpweya wowawasa.
Chilangochi chimapitirira kupyolera mu ndondomeko. Kuponyera mchenga ndi kuponya ndalama kumachitika pamalowo - osati kunja - kotero timawongolera mitengo ya nkhungu preheat, solidification gradients, ndi nthawi ya shakeout. Kupatuka kwa 2°C mu kutentha kwa nkhungu kumasintha kutalikirana kwa mikono ya dendrite ndi 12%, zomwe zimakhudza mwachindunji kutheka komanso kutopa kwanyumba zapampu ya piston. Ma cell athu a CNC amagwiritsa ntchito kutsimikizira kwa CMM pambuyo pochita movutikira, kumaliza, ndi kumaliza - osati kungoyang'ana komaliza. Timayesa kusuntha kwamafuta pamakina amitundu yambiri pamphindi 90 zilizonse chifukwa kukulitsa kwa 0.008 mm pakusintha kwa nyumba za spindle kunapangitsa kuti pakhale kupitilira madera olekerera GD&T.
Kumene makina oyendetsera ntchito amawonongeka-ndi zomwe zimagwira ntchito
Ena anganene kuti sitolo iliyonse yovomerezeka ya ISO 9001 imatha kunyamula ma alloys a cobalt-nickel ngati atapatsidwa zida zoyenera. Koma zochitika zenizeni zimafotokoza nkhani yosiyana. Carbide yokhazikika imayika fracture nthawi yomweyo pa AMS 5387 pamitengo yazakudya yopitilira 0.05 mm/rev. Timagwiritsa ntchito zida za PCD zokhala ndi geometry yolakwika, zoziziritsa kukhosi zomwe zimaperekedwa pa bar 120 kudzera munjira zamkati za spindle, ndi njira zosinthira zomwe zimasunga kuchuluka kwa chip-ngakhale kuzungulira 3D kozungulira ngati matupi okakamiza a valve okhala ndi makulidwe a 4.2 mm ndi zofunikira za 0.025 mm.
Kukhulupirika kwapamwamba kumafunikanso ngati geometry. Kutsirizitsa kalirole Ra 0.2 µm sikungalepheretse kupsinjika kwa dzimbiri ngati ma microcracks apansi pamadzi alipo kuchokera pakusankhidwa kolakwika kwamagudumu. Popanga zitsulo zosapanga dzimbiri zomwe zimagwiritsidwa ntchito pamapampu akunyanja, timayika electropolishing *pambuyo* kuwombera poyang'ana-osati m'mbuyomu-kuteteza kupsinjika kotsalira kotsalira ndikukwaniritsa kukana kwa dzimbiri pa ASTM A967. Kutsatizanaku sikongoyerekeza. Zimatsimikiziridwa pamagawo enieni opanga, ndikuwunika kwa magawo a SEM kutsimikizira kusakhalapo kwa mapangidwe oyera.
Kodi "mwambo" amatanthauza chiyani pazantchito zofunika kwambiri
Chikhalidwe sichimakhudza miyeso yosagwirizana yokha. Zimakhudza kugwirizanitsa ntchito. Pamene European OEM imafunikira ma winch center shaft rollers pamagalimoto opangira uinjiniya wa arctic-class, adafotokoza kulimba - koma samawerengera kulimba kwa kutentha kochepa. Tidayesa mayeso a Charpy V-notch pa -40 ° C pamitundu itatu yothira kutentha, tidalimbikitsa kusintha kwa kutentha, ndikupereka ma roller okhala ndi mphamvu ya 42 J (osati 27 J yokhayo). Lingaliro limenelo linalepheretsa kusweka kwa chiwombankhanga panthawi yomwe katundu wadzidzimutsa anasintha pa malo oundana ndi ayezi.
Mgwirizanowu umafikira pakupanga-kwa-kupanga. Timayimitsa ma callout a GD&T omwe amasemphana ndi ma angles opangira. Timatsanzira kupotoza kwamafuta mumilomo yopyapyala yokhala ndi mipanda ya cobalt panthawi yolumikizira yankho. Timapereka mayankho okhudza kupanga mkati mwa maola 48—osati masabata—chifukwa chitsanzo chimachedwetsa kutsimikizira nthaŵi. Oyang'anira ntchito yathu amalankhula bwino ASME Y14.5, osati Chingerezi.
Ngati mukufuna a mwambo aloyi Machining fakitale zomwe zimagwiritsa ntchito zitsulo ngati uinjiniya-osati kugula zinthu-mukuyang'ana kulumikizana kolimba pakati pa sayansi yazinthu, kukonza kwamafuta, ndikuwongolera kusuntha kolondola. Muyenera kutsata zolembedwa kuchokera pa nambala ya kutentha mpaka lipoti lomaliza loyendera. Mufunika anzanu omwe asintha matani a T800 alloy alloy curve pamitundu 17 yama hydraulic system. Mufunika kuphedwa kotsimikiziridwa - osati mawu okhoza. Ndilo gawo lomwe tsatanetsatane umatha ndipo ntchito imayamba.
