Ukubunjwa kwe-Sand-clay: izinzuzo

Izinqubo zokwakha isisekelo sezinsimbi zensimbi zihlelwe ngezindlela ezahlukene. Njengomkhiqizo ophumela kulo, kuncike kakhulu kwizici zesisekelo, ngesisekelo salo nto ehlongozwayo, okungukuthi, kusukela ekujuleni okugcwalisa izinto ezizayo zomsebenzi wokusebenza. Enye yezobuchwepheshe ezithandwayo ziphonsa ngesimo sobumba, esinika izinzuzo eziningi. Le ndlela isendulo kakhulu, kodwa isetshenziselwa ukukhiqiza emazingeni ahlukene - kusukela kumasifundisane amancane kuya kumabhizinisi amakhulu.

Ulwazi olujwayelekile mayelana nobuchwepheshe

Inqubo yokubunjwa yinkambiso yezobuchwepheshe, ngenxa yalokho umshini wokulungiselela noma umkhiqizo osuvele usuqedile nemigomo ye-geometric edingekayo yenziwe kusukela ensimbi encibilikisiwe. Ukuze ufeze isimo esifanele, imodeli ehlangabezana nezidingo isetshenziswa. Ukufaka isisekelo esifanayo sokukhishwa kuleli cala kuyifomu le-sandy-argillaceous. Iqukethe amaqembu amabili wezingxenye. Owokuqala uhlanganisa isihlabathi se-zirconium ne-quartz, neyesibili-kaolin nobumba bentonite. Ngakho-ke, kuhlanganiswa i-tooling eyodwa, okuyinto ekusetshenzisweni komsebenzi ithatha indaba yesikhathi esizayo sokusebenza. Kodwa ngisho lezi azizona zonke izingxenye ngesisekelo lapho ukukhishwa kutholakala khona ngamafomu enhlabathi-ama-argillaceous. Ubuchwepheshe abukwenzi ngaphandle kwekhamera yezimodeli, okuyihlobo lohlobo lwempahla yokuthenga esikhathini esizayo. Ukuze kusetshenziswe imodeli enjalo, izinto ezilula noma ezinamaphutha ezifana nezinkuni noma izinsimbi ezikhanyayo zisetshenziswa. Kodwa-ke, isisekelo esithambile sisetshenziswa kuphela ezimweni uma kudingeka ukuba uphinde uphinde uphinde uhlose ingxenye. Kodwa kwenzeka ukuthi amakhosi abhekene nemikhiqizo eseyiqedile kakade, imingcele yayo okudingeka iphindwe ngokuphonswa. Manje kufanele sihambe ngokuqondile ezinzuzo zaleli buchwepheshe.

Izinhlobo ezihlukahlukene

Ukuyinkimbinkimbi kokusebenzisa isikhunta esikhulu kanye namamodeli wokukhishwa ukuthi ubuchwepheshe abuhlinzeki ngokubhujiswa kwesakhiwo sabo. Lokhu kunciphisa kakhulu inqubo yokwenza umsebenzi, kucindezela imisebenzi yabasebenzi. Uma kwenzeka izinhlobo ze-sandy-clayey, imingcele enjalo ayitholakali, ngoba indlela yokuqala iqala ukusebenzisa isikhathi esisodwa sefomu. Kodwa-ke, lokhu akusho ukuthi ukusetshenziswa okusetshenziselwayo ukukhwabanisa kubanjwe ngokuyisisekelo. Ngenxa yezizathu zomnotho, ifomu ingasetshenziswa nge-serial, uma lokhu kungaphikisani nezidingo ekugcineni komphumela wenqubo. Izinzuzo zezobuchwepheshe nezenhlangano zokufaka amafomu enhlabathi-ama-argillaceous ikakhulukazi zinqunywa indlela yokusebenza okusebenzayo. Endabeni yokungahlali okuhlala unomphela, ungathembela ekukhipheni isikhunta ngaphandle kokulimaza, futhi nokuphonswa ngemingcele edingekayo. Lolu khetho luvame ukusetshenziswa emisebenzini nge-castings elula. Kodwa uma kungumbuzo wokuyinkimbinkimbi wezokwakha zokwakha, khona-ke ifomu elingasetshenzisiwe lingasetshenziswa, okungekho imingcele ngokwemigomo yomkhiqizo odingekayo.

Ukufinyeleleka kwezobuchwepheshe kwenhlangano yenqubo

Isibonelo sokusetshenziswa kwesibhakabhaka se-sand for casting sibonisa ukuthi kunamathuba amaningi kangakanani amasu okukhiqiza yendabuko angaqhathaniswa namanje. Kulokhu, lokhu kungenxa yokulula kwenhlangano yokukhipha. Ukusebenza kudinga kuphela isethi yezinto ezibalulwe ngenhla zefomu kanye ne-modeling rig engadingi ukuqaliswa kwezinqubo eziyinkimbinkimbi. Amamodeli okuqala wokubumba angenziwa ngamapulangwe ngethuluzi elikhethiwe lokumba. Ngaphandle kwezimboni ezithintekayo ekukhiqizeni ukubunjwa kwebunjwa obuyinkimbinkimbi, izindlela ezengeziwe zokucubungula nokufaka lesi sihloko zihilelekile. Futhi kunzima ukukhipha ngesimo se-sandy-clay, esenziwe ngensimbi nangeplastiki. Kodwa, futhi, lokhu kusebenza ezimbonini ezikhethekile. Ukuzivocavoca kubonisa ukuthi emhlabeni wonke ama-80-90% azo zonke izinkampani zenziwe ngokusekelwe kwamakhono alula kakhulu ngendlela yamathuluzi afanelekile kanye namagumbi okomisa wendabuko.

Ukwenza ngcono umnotho

Ngokuvamile, ukusebenzisa ithuluzi elilodwa kuhilela izindleko zenqubo. Ngakho-ke, izixazululo ezinjalo zibhekiswe kuphela ezimweni ezimbi kakhulu, uma ufuna ukwakha izingxenye noma imiklamo yamafomu angewona ajwayelekile. Kodwa umkhuba oguqukayo ubonisa isisekelo. Ukushaywa ngamafomu ama-sandilla-ama-arillaceous kufakazela ngokwezezimali ngisho nakulezo zimo lapho kusetshenziswa isisekelo esingasetshenzisiwe. Lokhu kungachazwa ngezindleko ezincane kokubili ifomu ngokwayo kanye nomklamo wokufanisa.

I-Universality of technology

Kunezinto ezimbalwa zokukhiqiza ezingahle zinciphise ububanzi balobu buchwepheshe. Isetshenziselwa embonini, ukwakhiwa, ukukhiqizwa okuncane nokukala okuncane kokufakelwa kwezinto zokufakelwa, kumasifundisane ezimele, njll Ngaphandle kwemigqa yokukhiqiza eqondile ephezulu, awuvumeli le nqubo, ngoba ayivumeli ukuqinisekisa izinga elifanele lokunemba kwezici ze-billet. Kodwa kusukela ekubukeni kokusetshenziswa kwe-metallic melts, kuphawulwe yonke indawo, okuyinto, ngaphandle kwamanye ubuchwepheshe, idala isikhunta somhlabathi. Kancane nje kubonisa izinsimbi ezingamukeleki kungaba yiqembu lezinhlobo ezifakiwe ezifakiwe. Izitsha zendabuko yokusika zisebenza kahle kulo msebenzi wokubumba.

Ukukhubazeka okungenzeka ukuthi kukhishwe

Iphuzu elibuthakathaka lale teknoloji, njengoba kukhonjisiwe ngenhla, yiyona ukunemba okuphansi kwimingcele yomsebenzi wokusebenza. Imikhiqizo itholakale yinkimbinkimbi, hhayi njalo ehambisana nendawo kanye nobukhona beziphambeko ngabanye. Le nuance yindawo ephikisanayo yokuhlukumeza futhi kulula ukuthola i-snap. Ngaphezu kwalokho, ukufaka ifomu lomsongo kuvumela izingozi zokuwela ekufakweni kwe-inclusions engekho emthethweni. Kuye ngensimbi ngokwayo, i-gas porosity nayo ingenzeka. Kodwa lokhu akusho ukuthi ukukhubazeka kuba yisithiyo esikhulu ekusetshenzisweni okubanzi kwesayensi yehlabathi. Ukukhokhela lokhu kuntuleka kungagcinwa yimithetho yokukhishwa kwekhwalithi.

Izincomo zokuthola i-quality billet

I-Technologists iyalulekwa ukuthi ihambisane nemithetho emibili eyisisekelo eyokuvumela ukuthi usondelane nokuthola umphumela olindelekile. Okokuqala, kuyadingeka ukuba ugweme ukusebenzisa le ndlela ngaphansi kwezimo zokungcolisa okuphansi kwensimbi. Iqiniso liwukuthi izinga eliphezulu lokupholisa lingakhuthaza ukupholisa okukhulu nokuqhakazila, okubangela ukwakheka kwezingqungquthela kanye nokugcwalisa phansi. I-nuance yesibili, kungakhathaliseki ukuthi ukuqhutshwa kochwepheshe kuhlobo olulodwa lwe-sandy-argillaceous akudingi, kubhekisela ekubhekaneni nokubekezelelana okuncane emthamo we-billet. Ukwandisa imingcele yokuqala esikhathini esizayo kuzovumela ukuthi ushintshe umkhiqizo ngaphandle kokufaka umonakalo ongalindeleki.

Isiphetho

Ubuchwepheshe bulula futhi bufinyeleleka, kodwa akusho ukuthi akubandakanyi intuthuko. Ngandlela-thile, ukubunjwa kweshlabathi kusezingeni eliphezulu, okuvumela ukwandisa inqubo nokuqeda ezinye zezinkinga zayo. Igatsha elibonakalayo nelithembisayo le ndlela libhekwa njengefomu elikhishiwe. Izimiso zokusebenzisa isihlabathi zihlala zifanayo, kepha iqembu labumba lezingxenye njengesizinda esibophezelayo kuleli cala alifakiwe.
