Lapho onjiniyela becacisa izingxenye zensimbi ezibekezelela kakhulu amaphampu asebenza ngogesi, amavalvu asendaweni kawoyela, noma amasistimu ewintshi ezimoto zobunjiniyela, abadingi nje “ukuphonsa.” Badinga ukuzinza kwe-dimensional ngaphansi kwengcindezi engu-200 MPa. Ubuqotho be-Microstructure ngemva kokwelashwa kokushisa. Isiphetho esingaphezulu esimelana nokugqokwa kwe-slurry. Futhi ukulandeleka okugcwele - kuze kufike eqoqweni elincibilikayo kanye nombiko wokuhlolwa okuqinile. Yingakho amaqembu okuklama eNyakatho Melika naseJalimane ebuyela njalo ku- imboni yomkhiqizi wokunemba ayigxilile ngevolumu, kodwa isiyalo se-metallurgical: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Kungani I-Cobalt Alloys Idinga Okungaphezu Kwe-Foundry Nje
Izisekelo eziningi zenza insimbi noma i-carbon steel. Bambalwa abaphatha ingxubevange ye-cobalt ye-AMS 5387 — ingasaphathwa eyokubamba ama-oda okuphinda amabhomu asekelwe ku-T800 asebenza ku-650°C ezindaweni ezinegesi emuncu. Sibone amakhasimende eshintsha abahlinzeki ngemva kwamaqoqo amathathu ahlulekile ezindlu zephampu ye-cobalt-nickel: ukulwa ngesikhathi sokunciphisa ingcindezi, ukuqina eduze noguquko odongeni oluncane, ama-callout e-GD&T aphuthelwe ngu-±0.03 mm ezindaweni ezibucayi zokuvala. Imbangela? Igebe phakathi kwamandla okusakaza nokulawula imishini yangemva kokusakazwa. I-QINGDAO QIANGSENYUAN ivala lelo gebe. Indawo yakhona ihlanganisa ukutshala imali, ukuphonsa isihlabathi, ukwenziwa kwemishini ye-CNC ye-multi-axis, nokwelashwa kokushisa kwe-vacuum - konke ngaphansi kophahla olulodwa oluqinisekiswe i-ISO. Awekho ama-handoffs. Akukho ukuhlonza kabusha okubalulekile. Akukho ukukhukhuleka okulinganayo phakathi kwejometri ekhonjiwe kanye nedatha yokugcina yomshini.
Ukuhlanganiswa Okuqondile Okumisa Ukubekezelelana - Hhayi Imigqa Yesikhathi Nje
Cabanga ngendlu yesilinda sephampu ye-piston. Iqala njengensimbi engagqwali esakhiwe ngesihlabathi engenalutho enemvume yomshini engu-1.5 mm. Bese ithola ukukhululeka ekucindezelekeni, ukugaywa okunamandla, ukwelashwa kokushisa (isixazululo se-anneal + ukuguga), ukunemba kokubhora kwama-coaxial bores, kanye nokugaywa kwendawo yokugcina ku-Ra 0.4 µm. Isinyathelo ngasinye sishintsha ingcindezi eyinsalela kanye ne-microstructure. Uma ukusakaza nokwenza imishini kumasayithi ahlukene, umlando wokushisa uyalahleka. Kwa-QINGDAO QIANGSENYUAN, ithimba elifanayo liphethe lonke uchungechunge - kusukela ekutholeni isitifiketi sempahla eluhlaza (konke ukushisa okulandelekayo kuya emibikweni yokuhlolwa komshini) kuya ekuhlolweni kwe-CMM kusetshenziswa izinhlelo ze-Zeiss CONTURA G2 ezilinganiswa nsuku zonke. Silinganise ukubekezelelana okuphindaphindekayo okungu-0.012 mm kuwo wonke u-120 mm wobude be-bore — ezingxenyeni lapho izinga lemboni livumela ±0.05 mm. Lokho kuvumelana kuvela ekulawuleni okuguquguqukayo abanye abakuphatha njengokumisiwe: izinga lokupholisa isikhunta, ukucisha izinga lokushisa eliphakathi nendawo, ukuchezuka kwesakhiwo phakathi ne-contouring ye-axis engu-5.
Lapho "Ukubekezelelana Okuphezulu" Kuhlangana Nomsebenzi Womhlaba Wangempela
Ukubekezelela okuphezulu akukhona nje ngama-microns emdwebeni. Imayelana nokuthembeka kokusebenza. Ipulaki ye-cobalt alloy kufanele ivalwe ngokumelene nokucindezela kokuhluka kwamabha angu-350 kuyilapho imelana nokukhala ngesikhathi sokusebenza okuphindaphindiwe. I-winch center shaft roller kufanele igcine ukujikeleza phakathi kuka-0.008 mm ngaphezu kwemijikelezo engu-10,000 yokulayisha ukushaqeka. Lezi akuzona izicaciso zelebhu - izindlela zokwehluleka esizibhale ekubuyiselweni kwenkambu. Amandla e-QINGDAO QIANGSENYUAN asekuxhumaniseni i-metrology nokusebenza: i-optical profilometry iqinisekisa ubuqotho bobuso ngaphambi kokumbozwa; ukuhlolwa kwe-ultrasonic kuqinisekisa ukuzwakala kwe-subsurface ekubunjweni kwesigaba esiwugqinsi; kanye nokuhlola okusebenzayo - njengezindlu zokushibilika kwengcindezi ukuya ku-1.5× ingcindezi yokusebenza - kwenzeka ngaphambi kokuthunyelwa. Izivumelwano zabo zokuhlola ezibhalwe phansi zifaka ukuqinisekiswa kwe-GD&T kuzo zonke izigaba, hhayi ukuhlola kokugcina. Kungaleyo ndlela abaletha ngayo izingxenye ezingajwayelekile lapho izindawo “ezisebenza ngomshini” zihlangana ne-ASME B46.1 Ra 0.2 µm — ngaphandle kokupholisha kwesibili.
Ukubambisana Ngale Kwe-oda Lokuthenga
Abaklami bavame ukubuza: “Ungayenza le geometry nge-T800?” Umbuzo wangempela uthi: “Kwenzekani esakhiweni sokusanhlamvu uma sinciphisa ukujiya kodonga ngo-1.2 mm lapha?” I-QINGDAO QIANGSENYUAN iphendula yomibili — phakathi nokubuyekezwa kobunjiniyela, hhayi ngemva kokusetshenziswa kwamathuluzi. Abaphathi bamaphrojekthi abo bahlola ukujiya kodonga ngokumelene nedatha yokufanisa yokuqinisa. Bamaka ama-engeli asalungiswa angahambisani nokususwa kwegobolondo le-ceramic. Baphakamisa izinguquko ezincane ze-radii ezinciphisa isikhathi somshini ngo-22% ngaphandle kokufaka engozini impilo yokukhathala. Lena akuyona isevisi yokweluleka - iwubunjiniyela obambisene obusekelwe eminyakeni engu-17 yokukhiqizwa kwephampu, i-valve, kanye nezinto ezisindayo. Ngokugijima kwesibonelo, isikhathi sokuhola sithatha izinsuku ezingama-28 kusukela ekuvunyweni komdwebo. Kuma-oda evolumu ephakathi (ama-50–500 ama-pcs/ngonyaka), ukuzinza kokulethwa kufinyelela ku-98.4% - kulandelelwa ngokuhlelwa okuhlanganisiwe kwe-ERP nezilawuli zokugeleza komsebenzi ezinciphile.
Uma ubheka phambili, isidingo sokukhiqiza okuxubile - lapho ukusakaza kuchaza i-geometry yobuningi futhi i-CNC ichaza izindawo ezisebenzayo - sizokhula kuphela. Izinto ezifana ne-cobalt-nickel superalloys ngeke zibe lula ukuzisebenzisa. Kodwa ikhono lokuzilawula, kusukela kumakhemikhali ancibilikayo kuya ku-contour eqediwe, lihlala liwujuqu. Uma ingxenye yakho elandelayo yensimbi ebekezelela kakhulu kufanele isebenze - ingagcini nje ngokulingana - qala ngo- imboni yomkhiqizi wokunemba ephatha i-metallurgy njengobunjiniyela, hhayi ubuciko.
