Bheka, ukulahlekelwa igwebu. Ngenye yalezo zinqubo ezidumaza kakhulu ngamandla ayo—umumo oseduze nenethi, amajiyometri ayinkimbinkimbi, ukwenziwa kwemishini encishisiwe. Kodwa hamba ungene ezisekelweni eziyishumi uthi uyakwenza, futhi ungase ubone izincazelo eziyishumi ezihlukene zempumelelo. Umbono oyiphutha omkhulu? Ukuthi kumane kuyindlela ehlanzekile yokufaka isihlabathi ngokwesiko. Akunjalo. Iwuhlelo oluphelele, futhi uma amaphethini akho egwebu, okokunamathela, ukuminyanisa kwesihlabathi, kanye nesango lokungena kungekho kumdanso ophelele, ontekenteke, ushisa i-polystyrene ebizayo ukwenza izicucu. Ngibone imizamo eminingi ehlulekile evela kubantu abaphatha iphethini yegwebu njengokuthi iyalahlwa kunokuba umnyombo wangempela wenqubo.
Iphoyinti Lokuqala Lokwenza noma-Ukuphuka: Iphethini ngokwayo
Konke kuncike kuphethini ye-foam. Akukona nje ukuma; isibambindawo esiguquguqukayo. Sakufunda kabuhlungu lokhu kusenesikhathi. Ukuthola ubuhlalu be-EPS obushibhile, obunobukhulu obuphansi kungase konge izindleko kusengaphambili, kodwa imigqa yokuhlanganisa ubuhlalu iba amaphuzu okuhluleka. Igwebu lidinga ukujiya ngokwanele ukuze likwazi ukuphatha ngaphandle kokuboleka, kodwa igremu ngalinye elingeziwe liyivolumu yegesi ngesikhathi sokuthululwa, okuthinta ukugeleza kwensimbi nobuqotho bokugcina. Ukuhlanganiswa kwephethini-ukunamathisela izingxenye eziningi zegwebu-kungomunye umbulali othule. Sebenzisa ingcina engalungile, futhi ayivali ilunga (okuholela ekungeneni kwensimbi kumthungo, iphutha elibi elibizwa ngokuthi i-veining) noma ishiya izinsalela zekhabhoni ezidala okufakiwe. Sishintshele entweni enamathelayo encibilikayo ekhethekile ukuze sithole amalunga abucayi ngemva kokuba inqwaba yamavalvu elokhu ehluleka kuma-flange. Yilawa ma minutiae ahlukanisa i-prototype kusukela kukhwalithi elungele ukukhiqiza.
Bese kuba khona ukunamathela, udaka lwe-refractory. Lokhu akuwona upende; kuyisithiyo kanye nesilawuli sokungena. Kujiye kakhulu, futhi igesi ephuma kugwebu elihwamukayo ayikwazi ukuphunyuka ngokushesha, okubangela ukuba insimbi imise noma iphinde ibuyele emuva. Izacile kakhulu, futhi isihlabathi siyabhodloka, senze indawo engaphezulu eqinile, ehlangene. I-viscosity idinga ukugadwa njalo—izinga lokushisa kanye nomswakama esitolo kuyithinta kakhulu. Sihlose ukunamathela esikhumbeni esifana ne-ceramic, esiqine ngokwanele ukugcwaliswa kwesihlabathi kodwa esintekenteke ngokwanele ukuqhekeka ngaphansi kwengaphambili lensimbi ukuze kuvunyelwe ukuphuma kwegesi. Ibhalansi oyizwayo, ngokwezwi nezwi, ngendlela econsa ngayo emunweni wakho.
Ngikhumbula iphrojekthi yendlu yephampu ehlangene, umsebenzi oyinkimbinkimbi wangaphakathi. Iklayenti beliyifuna ngensimbi eyi-ductile. Ama-run okuqala ayeyinhlekelele-ukuncipha kwe-porosity ehlangene ezingxenyeni eziwugqinsi. Igwebu, yiqiniso, liyanyamalala futhi lingashiyi isisindo esishisayo esichaziwe. Inkinga yayiwukuthi isango lethu, elikopishwe endleleni yokufaka isihlabathi, ayizange ibale ukulahlekelwa ukushisa okwengeziwe okuvela ekuboleni kwegwebu le-endothermic. Kwadingeka sihlele kabusha uhlelo lokuphakelayo ngokuphelele, sengeze izikhuphukeli ezengeziwe ezindaweni okungezona ezendabuko ukuze sinxephezele lowo mphumela wokupholisa. Yengeza amaphuzu okuthinta ama-machining kamuva, kodwa kwaba yilokho noma okulahliwe. Iphethini umkhiqizo, kuze kube ingekho.
Sand, Vibration, kanye Illusion of Simplicity
Isihlabathi esomile, esingaboshiwe. Kuzwakala kulula. Kodwa ukucinana kwayo kuzungeze iphethini entekenteke, emboziwe yilapho kuzalwa khona ukukhubazeka okuningi okubonakalayo. Ithebula lokudlidliza liyinhliziyo yalo. Udinga ukudlidliza okunezinhlangothi eziningi ukuze isihlabathi sigeleze kuyo yonke indawo ngaphandle kokukhipha noma ukuhlanekezela iphethini. Inolaka kakhulu, futhi ungakwazi ukugunda izindonga zephethini encane noma ubangele ukuqhekeka ngaphambi kwesikhathi. Ubumnene kakhulu, futhi uthola izindawo ezithambile esihlabathini, okuholela ekunyakazeni kodonga lwesikhunta kanye nokunemba kobukhulu—lokho esikubiza ngokuthi ukuqhuqha.
Sisebenzisa ingxube yesihlabathi se-silica, nakuba kwamanye amabanga ensimbi engagqwali siye sathuthela ku-zirconia ngenxa yokuqina kwayo okushisayo okuphakeme. Okubalulekile ukungaguquguquki. Noma yimuphi umswakama uyisitha; ihlangana nensimbi eshisayo kanye negwebu elibolayo ukuze kwakhe amaphakethe esitimu, kubangele izimbobo zokungena. Somisa isihlabathi endaweni yokomisa eyi-rotary uma kukhona umswakamo. Isinyathelo esengeziwe, kodwa ishibhile kunokuphatha ukushisa okugcwele kamuva ukuze uzame futhi uvale i-porosity ongakwazi nokuyibona phezulu.
Ukuthela ngokwako kuphambene nesimo sezulu kodwa kushubile. Uthela insimbi kulokho okungamafutha. Izinga libalulekile. Ihamba kancane kakhulu, futhi igwebu liwohloka ngaphambi kwengaphambili lensimbi, libangele ukuba imbobo igoqeke noma iwele isihlabathi. Ngokusheshisa kakhulu, futhi ukukhiqizwa kwegesi kungaphezu kokungena kwe-coating, okubangela isiyaluyalu nokufakwa kwe-slag. Ubheka izintuba zomusi, umbala nokugeleza kwawo kuyakutshela ukuthi ukusha kuhlanzekile yini. Intuthu emnyama, enamafutha isho ukusha okungaphelele, inkathazo. Iphuphu elizinzile, elimpunga-mhlophe yilokho okufunayo. Kuyinqubo yezinzwa kakhulu.
Lapho Ilingana Nalapho Ingangeni khona
Ukukhipha igwebu elilahlekile kukhanya emindenini ethile yezingxenye. Amabhulokhi enjini, amakhanda amasilinda, ama-manifolds—amajamo ayinkimbinkimbi anamaphaseji angaphakathi angadinga izinongo zesihlabathi eziyinkimbinkimbi nezimba eqolo. Ukuqedwa kokuhlanganiswa okuyinhloko kanye nokuphrinta okuyinhloko kuwukonga okukhulu emsebenzini futhi kuthuthukisa ukungaguquguquki kwe-dimensional. Enkampanini efana ne-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), enamashumi eminyaka egobolondweni nasekufakweni kwe-investimenti, ukwengeza igwebu elilahlekile kuphothifoliyo kwakumayelana nokunikeza inqubo efanele yejometri efanele. Kwesinye isikhathi, ingxenye esiyicaphunayo ingenziwa ngesikhunta segobolondo noma igwebu elilahlekile. I-breakpoint ngokuvamile iyinkimbinkimbi yangaphakathi kanye nevolumu. Ngokugijima kwezingcezu ezingu-500 ze-valve ye-hydraulic valve enegalari kawoyela ephambanayo, igwebu elilahlekile liyawina. Ngezingcezu ezingu-50 ze-high-temp turbine nozzle ku-cobalt alloy? Emuva ekulingiseni utshalomali.
Umkhawulo wezinto ezibonakalayo ungokoqobo. I-aluminium nensimbi empunga yizona ezithethelela kakhulu. I-Ductile iron idinga ukulawulwa okuqinile kwamazinga e-magnesium (ukubola kwegwebu kungathinta i-nodularization). Insimbi kanye ne-stainless kungenzeka, kodwa ukushaqeka okushisayo ekunambeni kuphezulu, futhi i-carbon pickup evela egwebu ukukhathazeka kwangempela. Senze imigijimo eyimpumelelo yamabakaki angenasici angu-304, kodwa idinga ubunikazi bobunikazi obunokuqina okuphezulu kanye nokuthela okunembe kakhulu, okusheshayo. Akukhona ukuhamba kwezinsimbi ze-alloy ephezulu lapha; ukutshala izimali kuseyinkosi yalokho, uma kubhekwa ubuchwepheshe be-QSY ngama-alloys asekelwe ku-nickel nama-cobalt. Udlala ngamandla enqubo.
Ngemuva Kwenqubo: Ukuhlola Kwangempela
I-Shakeout ilula—vele uphendule ibhokisi. Kodwa ukubukeka kokuqala kokulingisa isheke langempela. Indawo engaphezulu inesici, esimaholoholo kancane, ukuthungwa kwekhasi eliwolintshi kusukela kusixhumi esibonakalayo esinamathelisa. Icoke kakhulu kunokusakaza isihlabathi kodwa ayisheleli njengokutshala imali. Cishe njalo uzobona ifilimu ekhanyayo, enekhabhoni emakhaleni; ngokuvamile iqhuma egunjini lokuhlanza. Amaphutha ahlukile. Isihlabathi esigoqiwe sibonisa njengokuhlanekezela okungazelelwe, okubi. Ukungena kwensimbi kubukeka njengephiko elimaholoholo, eliyinsimbi eduze komthungo wephethini. I-gas porosity isakazeka kakhulu, ngokuvamile ingaphansi komhlaba.
Imishini yilapho ukuzinza kwe-dimensional kukhokha khona. Ngaphandle kwamashifu abalulekile, izici ze-datum zithembekile. Kodwa kufanele uqaphele indawo ye-spongy. Ngezinye izikhathi, i-millimeter nje noma amabili ngaphansi kwe-as-cast surface, kungase kube nongqimba lwe-micro-porosity kusuka kumagesi okubola kwegwebu. Akuhlale kunesici, kodwa uma unobuso obuvalekayo obubucayi, ucacisa ubuncane bokusika kwemishini okungu-2mm ukuze ungene ngaphansi kwakho. Sifunde lokhu ngemuva kokuthi inqwaba yezindlu ze-compressor iphumelele ukuhlolwa kwengcindezi ekuqaleni, kodwa yehluleka enkundleni ngemuva kokugqokwa okuncane. Umlandu kwakuwungqimba olunezimbotshana khona kanye endaweni evalekile eyayigqokwa ivulekile. Manje sekuyinothi elijwayelekile emdwebeni wezindawo ezibalulekile.
Imicabango Yokugcina: Ithuluzi, Hhayi Isimangaliso
Ngakho, kunjalo ukukhishwa kwegwebu elilahlekile ikusasa? Kwezinye izingxenye, ngokuphelele. Kuyisixazululo esihlakaniphile sezinkinga ezithile. Kodwa isiyalo esinzima, esibucayi. Ivuza ukucophelela futhi ijezisa ukuqagela. Akuyona into ovele uyengeze ku-Foundry. Idinga iseli elizinikele, ukusuka ekubumbeni iphethini ukuya ekuphatheni isihlabathi. Kumphakeli odidiyelwe ofana ne-QSY (ungabona ububanzi bekhono labo kokuthi https://www.tsingtaocnc.com), ingelinye ithuluzi lamasu. Ibavumela ukuthi baqondise iklayenti—ake sithi, othile odinga ingxenye yensimbi eqinile enamashaneli angaphakathi—endlela ephumelela kakhulu. Kwesinye isikhathi lokho kulahleka igwebu, kwesinye isikhathi kuyinqubo yabo yesikhunta esiyinhloko. Inani lisekwazini umehluko, ekuhlakanipheni kwaphansi kwesitolo kokuthi inqubo ngayinye izizwa kanjani uma isebenza kahle, futhi okubaluleke kakhulu, uma isizokonakala. Leyo yinto okungekho ncwajana engathwebula ngempela.
