Uma uzwa 'umkhiqizi wokusakaza ngokunemba', yini efika engqondweni? Kwabaningi, igama elihle nje le-Foundry eyenza izingxenye eziyinkimbinkimbi. Lowo umbono oyiphutha wokuqala. Akukhona nje ngobunkimbinkimbi; imayelana nayo yonke i-ecosystem yokulawula—kusuka kumswakama wegumbi lephethini ye-wax kuya ejikeni lokugcina lokwelapha ukushisa leblade ye-nickel alloy turbine blade. Ingxenye 'enembayo' ivamise ukudayiswa ngokweqile ngokumaketha, kodwa empeleni, iwukucutshungulwa kokulungiswa okukhulayo futhi ngezinye izikhathi, izifundo ezibuhlungu ze-metallurgy.
Umnyombo Wawo: Inqubo kanye Nokuxhumana Kwezinto Ezibalulekile
Ukusakaza okunembayo kweqiniso, kithi, kuncike ekusebenzisaneni phakathi kwenqubo nezinto ezibonakalayo. Awukwazi nje ukuthatha iresiphi yensimbi engagqwali engu-316 futhi ulindele ukuthi izokwenza okufanayo ekubunjweni kwegobolondo njengoba yenza ekubunjweni kokutshalwa kwezimali. Amandla we-thermal ahlukile. Ngikhumbula iphrojekthi eminyakeni edlule yengxenye yasolwandle lapho sasisebenzisa ibanga elijwayelekile. Ukumelana nokugqwala bekuvaliwe ngenxa yokuthi asizange sicabangele izinga lokupholisa elihamba kancane lenqubo yethu yokubumba igobolondo elithinta imvula ye-carbide. Lokho kube ukwehluleka okwalungisa kabusha iphrothokholi yethu yokuqinisekisa impahla.
Yilapho impilo yenkampani ikhuluma kakhulu. Thatha I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Ngaphezu kweminyaka engama-30 ekulingiseni nasekukhiqizeni imishini, leso sikhathi akuyona nje inombolo. Ihumusha kumtapo wolwazi ojulile, ocishe unembile wokuthi, ukusho, ingxubevange esekwe ku-cobalt iziphatha kanjani ngesikhathi sesigaba sokudonsa ukutshala imali umugqa uqhathanisa nezabo ukubunjwa kwegobolondo ukumisa. Ungathola indlela yabo enemininingwane endaweni yabo ku-https://www.tsingtaocnc.com. Akucwebezeli, kodwa ukugxila kuma-alloys akhethekile kukutshela ukuthi kungenzeka asebenzelana ne-aerospace noma izinhlelo zokusebenza ezishisa kakhulu lapho isayensi yezinto ezibonakalayo ingeyona into ecatshangelwayo.
Ukukhetha phakathi kwesikhunta segobolondo nokusakazwa kokutshalwa kwezimali kuwucingo lwakudala lokwahlulela. Isikhunta segobolondo, sisebenzisa isihlabathi esinamekwe nge-resin, siyathandeka enkingeni emaphakathi kanye nokusetshenziswa okukhudlwana kwezingxenye zensimbi noma zensimbi—cabanga ngezindlu zamaphampu. Iqinile. Ukutshala imali, indlela ye-wax elahlekile, eyezinto eziyinkimbinkimbi: izindonga ezincanyana, ama-face finishes amahle, lawo majometri emshinini angenakwenzeka kuma-alloys angenasici noma akhethekile. A umkhiqizi wokulingisa ngokunemba kuwufanele usawoti wawo awuphusheli omunye phezu komunye; bahlonza umsebenzi wengxenye, umthwalo, nendawo ezungezile kuqala.
I-Machining Inextricable Link
Akukho ukusakaza 'okuwumumo wenetha' wezinhlelo zokusebenza ezibalulekile. Noma ubani othi lokho weqa iqiniso lokuqeda. Yingakho ukuhlanganiswa kwe CNC imishini akuxoxiswana ngakho. Ukusakaza kunikeza ifomu eliseduze nenetha, kodwa umshini uqinisekisa ukunemba-isikhundla sangempela sezimbobo zamabholithi, indawo ye-Ra 0.8 ebusweni bokuvala. Sifunde kusenesikhathi ukuthi ukuhlukanisa abathengisi be-casting kanye nemishini yethula amaphupho amabi wokubekezelela. Umakhi usola ukuhlanekezela kuka-caster; u-caster usola ukulungiswa komshini.
Ukubona ukuthi i-QSY ibala umshini we-CNC eduze kwezinto zabo ezikhethekile zokusakaza kuyinkomba eqinile. Iphakamisa ukuthi baphathe lonke uchungechunge lwenani. Lokhu kulawula kubalulekile. Isibonelo, ukwenza umshini wokulingisa insimbi engagqwali eqinile kudinga izindlela ezithile zamathuluzi nezinto zokupholisa ukuze ugweme umsebenzi oqinisa ingaphezulu ngokuqhubekayo. Uma amathimba okulingisa nawomshini angaphansi kophahla olulodwa, angakwazi ukuqondisa umjikelezo wokulingisa wokukhulula ingcindezi nokulandelana komshini ukuze kuncishiswe ukuhlanekezela. Kungumdanso odidiyelwe.
Ikhanda elibuhlungu elisebenzayo lapha liyalungisa. Ubamba kanjani ukulingisa okuyinkimbinkimbi, okungalingani komshini ngaphandle kokunciphisa ingcindezi? Sichithe amaviki sidizayina futhi senza i-prototyping imihlathi ethambile noma ukulungiswa ngokwezifiso. Kungumsebenzi ongathandeki ongakaze uvele encwajaneni, kodwa kulapho impi yokunemba kwengxenye yokugcina inqotshwa noma ilahleka khona. Umkhiqizi ocwebezela lokhu cishe ukhiqiza imishini, engeza ingozi.
Lapho Izinto Zingahambi Kahle: Isifundo Sokugayina Nokudla
Uma bekumele ngikhombe indawo eyodwa ehlukanisa izitolo ezinekhono kwezinye, i-gating kanye nedizayini yesikhuphukeli. Iwubuciko obuningi kunesayensi, esekelwa isofthiwe yokulingisa manje, kodwa isadinga umuzwa. Ekuqaleni kwesikhathi sami, sasinenqwaba yabakaki bensimbi be-ductile ebonisa ukuncipha kwe-porosity ezingxenyeni eziwugqinsi. Ukulingisa kubukeke kuhlanzekile, kodwa siwushaye indiva umthelela wobubanzi obuqondile bokuqina bengxubevange. Isango belinomkhawulo kakhulu.
Isixazululo kwakungekhona nje ukwenza amasango abe makhudlwana. Kwakumayelana nokubeka kabusha amasango angaphakathi kanye nokushintsha idizayini yesikhuphukeli sentamo ukuze kwakhiwe indlela yokuqinisa eqondiswe kakhulu. Lolu uhlobo lolwazi oluyimfihlo a umkhiqizi wokulingisa ngokunemba buthelela emashumini eminyaka. Uyibona ezitolo eziphethe iphothifoliyo yezinto ezibanzi, njengalezo ezisebenza ngama-alloys asekelwe ku-nickel, anezidingo zokudla ezihluke kakhulu uma kuqhathaniswa nensimbi ye-carbon.
Ukuhlaziywa kokwehluleka kuyimayini yegolide. Yonke ingxenye elahliwe, ikhasimende ngalinye libuya endleleni evuzayo etholwe ngaphansi kokuhlolwa kwengcindezi, likufundisa okwengeziwe ngenqubo yakho kunokugijima okuyimpumelelo okuyikhulu. Ukhiye uwukuba nelebhu ye-metallurgical endlini ukwenza ukuhlaziya kwezigaba, i-microscopy, kanye ne-SEM ukuze ubone ukuncipha okuncane noma amaqoqo afakiwe. Ngaphandle kwalelo khono lokuxilonga, uyaqagela nje.
I-Alloy Gambit: Izinto Ezikhethekile
Ukusebenza ngama-alloys akhethekile afana ne-cobalt noma i-nickel-based iyinhlangano ehlukile. Izindleko zezinto ezingavuthiwe zizodwa zenza konke ukuthulula kube umcimbi wezinga eliphezulu. Akukhona nje ukuncibilika nokuthela; imayelana nokulawulwa komkhathi. Kwamaningi alawa ma-alloys, ubheka ukuncibilika kwe-vacuum nokuthulula ukuvimbela i-oxidation nokuthathwa kwegesi. Imajini yephutha insingo izacile.
Kulapho amakhono ashiwo womkhiqizi adinga ukucutshungulwa. Ukuthi usebenza ngama-alloys akhethekile kungasho ukuthi wenze izivivinyo ezimbalwa, noma kungase kusho ukuthi unesithando somlilo esizinikele se-VIM (Vacuum Induction Melting) kanye nomlando wokukhiqiza izingxenye ezibalulekile zendiza. Lesi sakamuva sibandakanya izindlela eziqinile zokunikeza izitifiketi. Uma ngibheka iphothifoliyo ehlanganisa lezi zinto, ngivele ngicabange ngezinqubo ezihambisanayo: ukucindezela okushisayo kwe-isostatic (HIP) ukuvala ama-voids angaphakathi, izixazululo zokushisa ukushisa kwezixazululo ezinezindawo zokushisa eziqondile.
Inkokhelo, nokho, isekusebenzeni. Ingxenye ye-nickel-based alloy esakazwe kahle futhi ecutshunguliwe ingasebenza esigabeni se-turbine lapho amazinga okushisa ancibilikisa insimbi engagqwali evamile. Leso isiphakamiso senani. Kodwa kufuna a umkhiqizi wokulingisa ngokunemba ukuba yingxenye ye-metallurgist, ingxenye kanjiniyela oshisayo, kanye nengxenye yezinga elishisekayo. Izinga le-scrap kule ngxenye liyizindleko zokwenza ibhizinisi, futhi libonakala enanini.
Ukuhlola Kwangempela Kokugcina: Ukuxhumana kuyinkosi
Wonke amandla obuchwepheshe asho okuncane uma ukuxhumana neklayenti kuphuka. Amaphrojekthi aphumelele kakhulu engibe yingxenye yawo abandakanya onjiniyela bekhasimende ekubuyekezweni kwethu kwenqubo. Sizowachaza ukuthi kungani siphakamise ukushintshwa kwe-engeli okusalungiswa noma ukulungiswa okuncane kodonga ukuze kube nokusakazwa okungcono. Kwakha ukwethembana.
Lena enye inzuzo ecashile yezindlu ezihlanganisiwe njengale eshiwo ekuqaleni. Uma ukusakaza nokwenza imishini kuhlangene, iluphu yempendulo iqinile. Umakhi wemishini angatshela unjiniyela wokulingisa, Sithola ukugqokwa kwamathuluzi okweqile kule flange; singalungisa ubulukhuni kule ndawo yasendaweni eqeqebeni elilandelayo? Leyo ngxoxo ephindaphindayo, esebenzayo ayinakwenzeka echungechungeni lokunikezela oluhlukene.
Ngakho, lapho kuhlolwa a umkhiqizi wokulingisa ngokunemba, bheka ngale kohlu lwemishini. Bheka izibazi, izifundo ezifundiwe, ukuzimisela ukuchaza ukuthi 'kungani' ngemuva kwezincomo zabo. Ukunemba kwangempela akukhona nje kuma-microns wokubekezelelana; kukunemba komcabango nolwazi olusetshenziswa kuzo zonke izigaba, kusukela esihlahleni se-wax kuya embikweni wokugcina we-CMM. Yilokho okuguqula ingxenye yensimbi ibe ingxenye ethembekile.
