Ukubunjwa kwesihlabathi kuyinqubo evamile yokulingisa

Ukukhishwa kwesihlabathi kuyinqubo evamile yokuphonsa, eyaziwa nangokuthi ukuphonsa kwesihlabathi.Kuyindlela yokwenza ama-castings ngokusebenzisa isihlabathi ekubunjweni kokubunjwa.

Inqubo yokukhipha isihlabathi ihlanganisa lezi zinyathelo ezilandelayo:

1. Ukulungiselela isikhunta: Yenza isikhunta ezimbili ezinama-concavities amahle kanye ne-negative ngokusho komumo nosayizi wengxenye.Isikhunta esiyiphozithivu sibizwa ngokuthi umgogodla, kanti isikhunta esinegethivu sibizwa ngebhokisi lesihlabathi.Lezi zibunjwa ngokuvamile zenziwe ngezinto eziphikisayo.

2. Ukulungiselela isikhunta sesihlabathi: Faka umongo ebhokisini lesihlabathi bese uligcwalisa ngesihlabathi sesisekelo esizungeze umgogodla.Isihlabathi se-Foundry ngokuvamile siyinhlanganisela ekhethekile yesihlabathi esihle, ubumba namanzi.Ngemuva kokugcwaliswa kuqediwe, isikhunta sesihlabathi sihlanganiswe ngokusebenzisa ukucindezela noma ukudlidliza.

3. Insimbi encibilikayo: Ukuncibilikisa insimbi oyifunayo ibe uketshezi, ngokuvamile kusetshenziswa isithando somlilo ukushisa insimbi.Uma insimbi isifinyelele endaweni efanele yokuncibilika, isinyathelo esilandelayo singaqala.

4. Ukuthulula: Insimbi ewuketshezi ithululelwa kancane kancane esikhunjeni sesihlabathi, igcwalise sonke isimo.Inqubo yokuthela idinga izinga lokushisa elilawulwayo nesivinini ukuze kugwenywe amabhamuza, ukushwabana kwemigodi noma okunye ukukhubazeka.

5. Ukuqiniswa Nokupholisa: Uma insimbi ewuketshezi ekubunjweni isipholile futhi yaqina, isikhunta singavulwa futhi ukubunjwa okuqinile kukhishwe esikhunjeni sesihlabathi.

6. Ukuhlanza kanye nokucutshungulwa kwangemuva: Ama-castings akhishiwe angase abe nesihlabathi noma i-grit enamathiselwe phezulu futhi adinga ukuhlanzwa nokusikwa.Izindlela zemishini noma zamakhemikhali zingasetshenziswa ukususa inhlanzi kanye nokwenza ukunquma nokwelashwa okudingekayo.

Ukubunjwa kwesihlabathi kuyindlela yokulingisa eguquguqukayo neyongayo efanele ukukhiqiza izingxenye zensimbi ezinosayizi nobujamo obuhlukahlukene.Isetshenziswa kakhulu ezimbonini ezifana nezezimoto, imishini, i-aerospace kanye namandla.

Inqubo yokukhipha isihlabathi ingafinyezwa kalula njengezinyathelo ezilandelayo: ukulungiswa kwesikhunta, ukulungiswa kwesihlabathi, insimbi encibilikayo, ukuthululwa, ukuqiniswa nokupholisa, ukuhlanza kanye nokucubungula emva kokucubungula.

Ukubunjwa kwesihlabathi kungahlukaniswa ngezinhlobo ezilandelayo ngokuya ngezibunjwa zesihlabathi ezihlukene:

1. I-Mixed Sand Casting: Lolu uhlobo oluvame kakhulu lokuphonsa isihlabathi.Ekubunjweni kwesihlabathi esixubile, kusetshenziswa isihlabathi esiyinhlanganisela esinesihlabathi, isibopho namanzi.Lesi sikhunta sesihlabathi sinamandla aphezulu kanye nokuqina futhi silungele ukukhiqiza ama-castings amancane, aphakathi nendawo kanye namakhulu.

2. I-binder sand casting: Lolu hlobo lokubunjwa kwesihlabathi lisebenzisa isikhunta sesihlabathi esinesibophezelo esikhethekile.Izibophezelo zithuthukisa amandla nokuqina kwesikhunta sesihlabathi kuyilapho zithuthukisa ikhwalithi yangaphezulu nokunemba kokubunjwa.

3. Ukubunjwa kwesihlabathi esiqinile: Ukubunjwa kwesihlabathi esiqinile kusebenzisa isikhunta sesihlabathi esiqinile esimelana nomlilo ophezulu kanye nokuqina.Lesi sikhunta sesihlabathi silungele ukukhiqiza ukulingwa okukhulu nokunomthwalo omkhulu, njengamabhulokhi enjini nezisekelo.

4. Ukubunjwa kwesihlabathi ngendlela yokudiliza: Kulolu hlobo lokubunjwa kwesihlabathi, izindlela ezihlukene zokudiliza zisetshenziswa ukwenza ukulungisa nokuthatha isikhunta sesikhunta sesihlabathi kube lula.Izindlela zokukhishwa ezijwayelekile zifaka ukukhishwa kwesihlabathi esiluhlaza, ukukhishwa kwesihlabathi esomile kanye nokukhipha isihlabathi somenzeli.

5. Ukubunjwa kwesihlabathi okuyimodeli ehambayo: Ukubunjwa kwesihlabathi okuyimodeli enyakazayo kuyindlela yokuphonsa isihlabathi esebenzisa isikhunta esinyakazayo.Le ndlela ilungele ukukhiqiza ama-castings anezimo eziyinkimbinkimbi kanye nezakhiwo zangaphakathi zomgodi, njengamagiya nama-turbines.

Okungenhla kuyinqubo evamile kanye nokuhlukaniswa okuvamile kokusakazwa kwesihlabathi.Inqubo ethile kanye nezigaba zingashintsha ngokuya ngezidingo ezihlukene zokulingisa nezinto zokwakha.
