Uma abantu abaningi bezwa 'ukusakazwa kwensimbi ngokwezifiso', bafanekisela ukuhumusha okulula ukusuka kufayela le-CAD kuya engxenyeni eqediwe. Lowo umbono wokuqala, futhi omkhulu kunayo yonke, oyiphutha. Akuyona i-photocopy. Kuyizingxoxo phakathi kwenhloso yokuklama kanye nomthetho wemvelo, lapho ukuziphatha okubonakalayo, amandla okushisa, nesisindo esiphelele sensimbi encibilikisiwe kunezwi lokugcina. Ngibone amadizayini amaningi aklanywe kahle ehlala phansi esitolo ukuze embule amaphutha abalulekile okukhiqizwa kwevolumu—ama-undercuts abamba ama-cores, ukuguquguquka kokuqina kodonga okuqinisekisa ukushwabana kwe-porosity, noma izindawo zobuhle ezicaciswe kuma-alloys okubulala ukuze kuqedwe. Ingxenye 'yangokwezifiso' ayikona nje ukwenza isimo esiyingqayizivele; kumayelana nokwenza ngokwezifiso yonke inqubo, kusukela kusistimu ye-gate kuya ekwelashweni kokushisa, ukwenza lowo mumo usebenze. Kuqala ngokuqonda ukuthi yini oyicelayo ngempela insimbi.
I-Foundry Floor Reality Check
Ake sikhulume ngenqubo yokubumba igobolondo, enye yezindlela zethu eziyinhloko ku-QSY. Imvamisa ihlanganiswa nokufaka utshalomali, kodwa iqiniso phansi libuhlungu kakhulu. Wakha igobolondo le-ceramic elizungeze iphethini yegwebu noma ye-wax, isendlalelo ngesendlalelo. Ukunemba kuhle, kodwa ubuciko bangempela buse-slurry viscosity kanye nosayizi wezinhlamvu zesihlabathi se-stucco. Kwenze kube okungalungile, futhi igobolondo lingase lintule amandla okuphatha ukuthela noma lingakwazi ukungena emanzini livale amagesi, okuholela kuma-blowholes. Ngikhumbula inqwaba yezindlu zamaphampu ensimbi engagqwali eminyakeni embalwa edlule. Umklamo wawunalezi ziteshi ezijulile, ezincane. Amagobolondo ayebukeka elungile ephuma esomisini, kodwa ngesikhathi sokuthululwa, saba nokuqhekeka kwegobolondo okuyinhlekelele. Inkinga kwakungeyona insimbi; kwakuwukuthi ukumelana nokushaqeka okushisayo kwegobolondo kwakungakwazi ukumelana nokushisa okusheshayo, okungalingani okuvela ku-geometry. Kwakudingeka sibuyele emuva, silungise ukwakheka kwe-binder, futhi sehlise izinga lokuthela lokuqala. Yengeze izindleko nesikhathi iklayenti ebelingasilindele, kodwa kwaba yileso noma yachitha konke ukusebenza.
Yilapho iqala khona ukusebenza iminyaka engu-30 yokusebenza kwe-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ekhuluma ngayo. Akuyona nje inombolo; iwumtapo wezincwadi wengqondo walokhu kwehluleka nokucishe kuphuthelwe. Uthuthukisa umuzwa. Uma umdwebo omusha ungena ukukhishwa kwensimbi ngokwezifiso, awubheki nje ubukhulu. Ulingisa ngokwengqondo ukugcwaliswa, iphethini yokuqinisa, lapho izindawo ezishisayo zizoba khona. Ubheke lelo flange elincanyana elixhunywe kumphathi omkhulu kanye nokucabanga, Lokho kuzodonsa futhi kugoqe ngaphandle kokuthi silungise ukupholisa. Lesi sahlulelo sokuqala yilokho okuhlukanisa ingxenye edlula i-QC kwenye eyenza ngokwethembeka ensimini.
Ukukhetha okubalulekile kungenye indawo yamabhomu. Amaklayenti ngokuvamile azenzakalela ku-304 angenasici ngokumelana nokugqwala. Kodwa ezingxenyeni ezidinga amandla aphezulu kanye nokumelana nokugqoka emazingeni okushisa aphakeme, njengezingxenye ezithile ze-turbine, lokho ukukhetha okubi. Kudingeka siqondise amakhasimende kuma-alloys akhethekile, njengama-alloys asekelwe ku-nickel noma e-cobalt. Lezi izilo ezahlukene ngokuphelele. Izici zabo zokuncibilika zihlukile, zivame ukudabuka kakhulu, futhi zidinga imithetho ethile yokwelashwa kokushisa. Ukuzicuculula ngokuhamba kwesikhathi, esiphinde siziphathe ngaphakathi endlini nesigaba sethu se-CNC, kudinga amathuluzi akhethekile kanye nokuphakelayo/isivinini. Iphuzu liwukuthi, ukwenza ngokwezifiso kwangempela kusho ukuqondanisa izakhiwo ezingokwemvelo zengxubevange nezidingo zokusebenza zengxenye kusukela engxoxweni yokuqala.
Ukusakaza Kwezimali: Ukunemba nokubamba
Manje, ukuze uthole inkimbinkimbi yangempela kanye nokuqedwa kwendawo, siya ekutshalweni kwezimali (i-wax elahlekile). Lapha yilapho uthola khona lezo zingxenye eziseduze-netha ezinomumo omncane. Kodwa 'okuncane' akuyena 'ziro'. Kusafanele ngikuchazele lokho kubasiki bengqephu. Iphethini ye-wax ngokwayo kufanele ikhishwe ku-metal die, ngakho-ke kuhlala kukhona ama-engeli asalungiswa, ngisho noma eyihafu yedigri. Okunye okubanjiwe yi-ceramic core. Kumaphaseji angaphakathi, udinga umongo ongakwazi ukumelana nokuthululwa kwensimbi kodwa bese ukhishwa ngamakhemikhali ngemva kwalokho. Ukudizayina ingqikithi eqine ngokwanele futhi esusekayo kuwukukhethekile okuncane ngokwakho. Sake sasebenza ngokuningi ngeziteshi zangaphakathi eziphambanayo. I-core geometry yayintekenteke kangangokuba yayilokhu iphuka ngesikhathi sokujova i-wax. Isixazululo sasihilela ukuklama kabusha okuyisisekelo ngezisekelo zangaphakathi ezazizoncibilika kamuva, kwengezwe izinyathelo nezindleko. Isilinganiso sokuqala seklayenti sasisekelwe kunqubo evamile; izindleko zokugcina zibonise ubunkimbinkimbi bangempela.
Lokhu kuhlotshaniswa nesevisi edidiyelwe ehlinzekwa yi-QSY. Ngoba siphatha sobabili ukukhishwa kwensimbi ngokwezifiso kanye ne-CNC machining eyalandela ngaphansi kophahla olulodwa, sinenzuzo ebalulekile. Singaklama inqubo yokulingisa sicabanga ngomshini. Mhlawumbe sengeza isitoko esincane esengeziwe (isibonelelo sokuqeda) ebusweni obuthile be-datum ukuze siqinisekise ukuthi umakhi wemishini unendawo ehlanzekile, efanayo azoyibamba. Noma singase siphakamise ukushintsha umugqa wokuhlukanisa ngamamilimitha ambalwa ukuze ugweme ukuthi udlule endaweni ebalulekile yokuvala edinga ukuphela okuphelele. Lokhu kusebenzisana akulona nje ithiyori; kuvimbela ubuhlungu bekhanda phansi komfula. Ingxenye edlala kahle kodwa engakwazi ukubanjwa ngokuvikelekile ku-vise ye-CNC iyingxenye ehlulekile.
Ukulawulwa kwekhwalithi kuwukulandisa, hhayi isithombe esincane. Umbiko wokuhlola oqinile ukunika inombolo, kodwa awukutsheli ukuthi kungani inqwaba yezingxenye zensimbi ekhonjiwe ibonise ukuhluka kobulukhuni. Kufanele ufunde indaba. Ingabe kube ukuguquguquka okuncane kokulingana kwekhabhoni nokuncibilika? Ingabe izinga lokupholisa endaweni ye-shakeout lihluka ngoba umthwalo ubugcwele ukuqina? Sifaka la mapharamitha ngokuzikhandla. Ngohlelo lwakamuva lwabakaki bensimbi be-ductile, silandelele izinga lokushisa lesikhunta lapho sithela, isikhathi sokupholisa sangemva kokusakazwa, kanye nomjikelezo we-ovini onembile we-austempering oven pallet ngayinye. Lapho ikhasimende licela umkhondo wokucwaninga, singanikeza uhlu lozalo oluphelele lwezingxenye zalo. Lokho ukujula kokulawula kwesimanje ukukhishwa kwensimbi ngokwezifiso izimfuno.
Lapho Izindlela Ezikhethekile Ziyinkinga
Ukusebenza ngama-alloys akhethekile, njengalawo asuselwa ku-nickel esivame ukuwacubungula, kuwumsebenzi oqhubekayo wokulawula izingqinamba. Lawa ma-alloys akhethwa ezindaweni ezimbi kakhulu-ukushisa okuphezulu, ukugqwala okuphezulu, ukucindezeleka okukhulu. Kodwa zona kanye izakhiwo zazo zenza kube nzima ukuphonswa. Anamaphuzu aphezulu okuncibilika, okusho ukuthi ukuhlasela okushisayo okunolaka ezintweni zesikhunta. Zivamise ukuba nebanga elincane lokuqanda, okusho ukuthi zisuka oketshezini ziye kokuqinile ngokushesha okukhulu, okungaholela ekuphambeni kahle uma isango lingaklanyelwe kahle ukugcwalisa isikhunta ngokushesha nangokuyaluza.
Ngikhumbula iphrojekthi ehilela isihlalo sevalvu yengxube ye-cobalt yemboni kawoyela negesi. Ingxubevange yayingagugi ngendlela emangalisayo, kodwa futhi yayithambekele ekubeni nenkinga ebizwa ngokuthi i-freckling - ukuhlukaniswa kwamakhemikhali endaweni okubonakala njengamachashaza ku-macro-etch. Imbangela? Izinga lokuqinisa kancane kakhulu. Kwakudingeka siklame kabusha isikhunta ngokugodola okwengeziwe—ithusi noma insimbi emunca ukushisa endaweni ethile—ukuze siphoqelele insimbi ukuba iqine ngokushesha nangokufana. Kuthathe abalingisi abambalwa bokuhlola, ukuhlukanisa amasampula kanye nokunamathisela isikhathi ngasinye, ukuze kulungiswe ukubekwa okubandayo nosayizi. Lokhu akukho kunoma iyiphi incwadi yokudlala ejwayelekile; kuyaphindaphinda, ukuxazulula izinkinga ngezandla.
Okuthathwayo lapha ukuthi ukucacisa okubalulekile kwe-premium akukuniki ngokuzenzakalelayo ingxenye yeprimiyamu. Kudinga i-Foundry ekwaziyo ukuhlanganisa leyo mpahla ukuze ibumbe. Kudinga izinqubo ezifana nokuncibilika kwevacuum noma ukuthululwa kwe-atmosphere evikelayo ukuze kuvinjwe i-oxidation. Idinga i-post-casting HIP (Hot Isostatic Pressing) ukuvala noma iyiphi i-micro-porosity esele. Uma ubheka amakhono asohlwini lwesayithi efana ne-https://www.tsingtaocnc.com, uhlu lwezinto ezisetshenziswayo nezinqubo akuyona nje imenyu. Kungumbhalo omfishane wesethi yamakhono aqoqiwe, azuzwe kanzima ekuphatheni leyo mindeni yezinto ezibonakalayo.
I-Machining Handoff: Lapho Inhloso Yokusakaza Ihlangana Namathuluzi Okusika
Yilapho izitolo eziningi ezididiyelwe ziwa khona. Umnyango wokulingisa uletha ingxenye ezophrintwa, kodwa umnyango wemishini uyiphatha njengocezu lwesitoko se-billet. Abakucabangi ukucindezelwa okungokwemvelo kokulingisa, amandla okuba namachashaza aqinile kusukela ekupholiseni okungalingani, noma umphumela wesikhumba (ungqimba lwangaphandle lokulingisa luvame ukuba nesakhiwo esincane esihlukile). Lokhu sikugwema ngokuba nokuhamba komsebenzi okuqhubekayo. Unjiniyela ofanayo owengamele ukulingisa kokuqinisa ukusakaza uzovame ukubonisana ngohlelo lomshini we-CNC.
Isibonelo esisebenzayo: ukulungisa ubuso obukhuphukayo ekubunjweni kwensimbi.
