Ilahlekile i-foam ekubunjweni

 Ukubuka konke kwe-1.1

Ngo-1958, uHF Shroyer wasungula ubuchwepheshe bokwenza izinsimbi zensimbi ngamamodeli epulasitiki anwebekayo futhi wathola ilungelo lobunikazi. Imodeli esetshenziswe ekuqaleni yayenziwe ngebhodi le-polystyrene (EPS) futhi yabunjwa ngesihlabathi esine-binder. Izinkampani zaseJalimane iGrunzweig neHarrtmann bathenga leli patent balithuthukisa balisebenzisa. Ubuchwepheshe bokusebenzisa isihlabathi esomile esingahlanganisiwe ukukhiqiza ukusakazwa kamuva kwaba nelungelo lobunikazi yi-TRSmith ngo-1964. Ngaphambi kuka-1980, ukusetshenziswa kwenqubo yesihlabathi esomile engenabinder kwakufanele kuvunyelwe yi-Full Mold Process (Inc). Ngemuva kwalokho, ilungelo lobunikazi belingavumelekile.

Indlela ejwayeleke kakhulu futhi ephathekayo ukufaka imodeli efakwe izinto eziyinkimbinkimbi ebhokisini lesihlabathi, ugcwalise imodeli ngesihlabathi esomile ngokuqinile, bese uthela insimbi engamanzi ukufaka imodeli yegwebu. Le nqubo yokusakaza ibizwa ngokuthi: ukulahleka kwe-foam foam (i-EPC), i-gasification mold casting kanye nokuqina kwesikhunta, njll.Ikomiti Elilahlekile Lamagwebu le-American Foundry Association lamukela "ukulahlwa kwe-foam" njengegama lenqubo.

Ukulahleka kwe-foam elahlekile kuyinqubo yokuphonsa entsha engasetshenziswa ukukhiqiza izingxenye zesistimu yamandla wensimbi engeyona eyensimbi ne-ferrous, kufaka phakathi: amabhlogo wesilinda, amakhanda wesilinda, ama-crankshafts, amabhokisi wamagiya, amapayipi wokungenisa, amapayipi wokukhipha nezindawo zokubopha. Inqubo ukugeleza elahlekile foam asakazwe kanje:

1) Ukwenza amagwebu ngaphambi kwesikhathi
Ukukhiqizwa kweModeli yisinyathelo sokuqala senqubo yokulahla amagwebu elahlekile. Ngokuphonsa okuyinkimbinkimbi njengamakhanda wesilinda, amamodeli ama-foam amaningana adinga ukwenziwa ngokwahlukana, abese anamathiselwe kwimodeli ephelele. Imodeli ngayinye yebhlokhi idinga isethi yezikhunta zokukhiqiza. Ngaphezu kwalokho, iqoqo lesikhunta lingadingeka ekusebenzeni kokunamathisela ukugcina ukuma okunembile kwebhulokhi ngayinye. Inqubo yokubumba imodeli ihlukaniswe ngezinyathelo ezimbili. Isinyathelo sokuqala ngukuthi ubuhlalu be-polystyrene bunwetshwe ngaphambili baba yisilinganiso esifanele, esivame ukwenziwa ngokushisa okusheshayo ngomphunga. Lesi sigaba sibizwa ngokuthi ukwandiswa kwangaphambili.

2) Model ukwakha
Ubuhlalu obunwetshiwe kufanele buqiniswe kuqala, bese buthunyelwa ku-hopper yomshini wokubumba, bese bufakwa emgodini wokuphakela. Ngemuva kokuthi umgodi wesikhunta ugcwale ubuhlalu obunwetshiwe ngaphambili, kwethulwa umusi ukuze unciphise ubuhlalu. Ukunwetshwa, ukugcwalisa zonke izikhala nokuhlangana emzimbeni owodwa, ngaleyo ndlela kuqedelwe inqubo yokukhiqiza yemodeli yegwebu, lesi sigaba sibizwa ngokuthi ukubunjwa kwe-autoclave.

Ngemuva kokubumba, isikhunta selehlile ngokugeleza okukhulu kwamanzi emgodini opholile wamanzi wesikhunta, bese kuvulwa isikhunta ukukhipha isikhunta. Ngalesi sikhathi, izinga lokushisa lesikhunta landa futhi amandla aphansi. Ngakho-ke, ukunakekelwa kufanele kuthathwe ngesikhathi sokudilizwa futhi kugcinwa ukuvikela ukusonteka nokulimala.

3) Inhlanganisela yeqoqo lemodeli
Ngaphambi kokuba imodeli isetshenziswe, kufanele igcinwe isikhathi esifanele ukuyenza ivuthwe futhi izinze. Isikhathi esivamile sokugcina imodeli sifinyelela ezinsukwini ezingama-30. Kwimodeli eyakhiwe isikhunta esakhiwe ngokukhethekile, idinga ukugcinwa amahora amabili kuphela. Ngemuva kokuthi imodeli ivuthwe futhi yazinza, ingahlukaniswa kabili. Amamodeli we-block ahlanganiswe ndawonye.
I-block model gluing yenziwa emshinini wokunamathisela othomathikhi usebenzisa i-hot melt glue. Amalunga wendawo ehlanganisiwe kufanele avalwe ngci ukuze kuncishiswe amathuba okusakaza amaphutha.

4) Model cluster cwilisa enamathela
Ukuze kukhiqizwe ukusakazwa okuningi ngebhokisi ngalinye, kwesinye isikhathi amamodeli amaningi anamathelwa ezigabeni, futhi amaqoqo ezimodeli afakwa kupende wokuphikisa, abese omiswa kuhhavini lokujikeleza komoya cishe ngo-30-60C (86-140F) okwe-2 kuye ku-3 Ngemuva amahora, omile, faka iqoqo lemodeli ebhokisini lesihlabathi, uligcwalise ngesihlabathi esomile bese udlidliza uvalwe. Zonke izimbotshana zangaphakathi nesihlabathi esomile sangaphandle seqoqo lemodeli kumele zihlanganiswe futhi zisekelwe.

5) Ukuthela
Ngemuva kokuthi iqoqo lemodeli ligcwaliswe ngesihlabathi esomile ebhokisini lesihlabathi, isikhunta singathululwa. Ngemuva kokuthululwa kwensimbi encibilikisiwe kwisikhunta (izinga lokushisa lisakazwa cishe ngama-760C / 1400F we-cast aluminium, futhi cishe ngo-1425C / 2600F ngensimbi yensimbi), imodeli iba vaporized. Insimbi ithathelwa indawo yenziwa ukusakaza. Umdwebo 1 umdwebo ohleliwe webhokisi lesihlabathi nokuthululwa kwenqubo yegwebu elahlekile.

Ngo elahlekile Foam inqubo ekubunjweni, ijubane ethela kubaluleke kakhulu ukwedlula wendabuko thusi eziyize. Uma inqubo yokuthela iphazanyiswa, isikhunta sesihlabathi singawa futhi sidale udoti. Ngakho-ke, ukuze wehlise umehluko phakathi kokuthululelwa ngakunye, kungcono ukusebenzisa umshini wokuthela othomathikhi.

6) Ukuwa kwesihlabathi
Ngemuva kokuthululela, ukusakaza kuyaqina futhi kuphole ebhokisini lesihlabathi, bese kuwela esihlabathini. Ukuwa kwesihlabathi sokuphonsa kulula, futhi ukuphonsa kuwela esihlabathini esomile lapho ibhokisi le-sandbox ligingqika. Ngemuva kwalokho, ukusakazwa kwehlukaniswa ngokuzenzakalela, kuhlanzwe, kuhlolwe, futhi kuthuthwe kuhanjiswe ebhokisini lokusakaza.

Isihlabathi esomile singaphinda sisetshenziswe ngemuva kokupholisa, futhi ezinye izinqubo ezingeziwe azisetshenziswa kakhulu. Izindwangu zensimbi zingasuswa futhi zisetshenziswe ekukhiqizeni.
