1- Kuyini Ukusakazwa Kwesanti?
Ukubunjwa kwesihlabathikuyinqubo yendabuko kodwa futhi yesimanje. Isebenzisa isihlabathi esiluhlaza (isihlabathi esimanzi) noma isihlabathi esomile ukwenza izinhlelo zokubumba. Ukulingisa kwesihlabathi esiluhlaza kuyinqubo endala yokulingisa esetshenziswa emlandweni. Lapho wenza isikhunta, amaphethini enziwe ngokhuni, insimbi noma ipulasitiki kufanele akhiqizwe ukuze enze umgodi ongenalutho. Insimbi encibilikisiwe bese ithela emgodini ukuze yakheukusakazangemva kokupholisa nokuqiniswa. Ukulingisa isihlabathi kubiza kancane kuneezinye izinqubo zokulingisakokubili ukuthuthukiswa kwesikhunta kanye nengxenye yokuphonsa iyunithi.
Ukubunjwa kwesihlabathi, njalo kusho ukukhishwa kwesihlabathi esiluhlaza (uma kungekho ncazelo ekhethekile). Nokho, namuhla, ezinye izinqubo zokubunjwa nazo zisebenzisa isihlabathi ukwenza isikhunta. Banamagama abo, njengokuthiukuphonsa igobolondo, i-furan resin ehlanganiswe nesihlabathi (alukho uhlobo lokubhaka),ukukhishwa kwegwebu elilahlekilekanye ne-vacuum cast.
2 - Kwenziwe Kanjani Ukufakwa Kwesihlabathi?
Sinezinhlobo ezahlukene zokulingisa ozikhethele zona. Ingxenye yenqubo ozikhethela yona yephrojekthi yakho kuzoba ukukhethwa kwenqubo yokusakaza ezosebenzela izidingo zakho kangcono. Ifomu elidume kakhulu ukulingisa isihlabathi okubandakanya ukwenza umfanekiso wesiqeshana esiqediwe (noma iphethini) esicindezelwa ngesihlabathi kanye nezithasiselo zokuhlanganisa ukuze kulolonge ukulingwa kwensimbi kokugcina. Iphethini isusiwe ngemva kokuba isikhunta noma umbono sewenziwe, futhi insimbi yethulwa ngesistimu yomgijimi ukuze igcwalise umgodi. Isihlabathi nensimbi kuyahlukaniswa futhi ukulingwa kuyahlanzwa futhi kuqedwe ukuthunyelwa kumakhasimende.
3 - Kusetshenziselwani Ukubunjwa Kwesanti?
Ukubunjwa kwesihlabathizisetshenziswa kabanzi ku-aizimboni ezahlukenekanye nezinto ezisetshenziswayo zikagesi, ikakhulukazi zokulingisa ezinkulu kodwa ezinomthamo omncane onzima. Ngenxa yezindleko eziphansi zokuthuthukiswa kwamathuluzi nephethini, ungatshala izindleko ezifanele ekubunjeni. Ngokuvamile, ukukhishwa kwesihlabathi kuyisinqumo sokuqala semishini esindayo njengamaloli athwala kanzima, izimoto zesitimela ezithwala impahla, imishini yokwakha, ama-valve, amaphampu namaphampu.amasistimu we-hydraulic. Ikakhulukazi, ii-ductile iron sand castingszisetshenziswa kakhulu ezimbonini zanamuhla.
4 - Yiziphi Izinzuzo Zokusakaza Isihlabathi?
✔ Izindleko Eziphansi ngenxa yezinto zayo zokubumba ezishibhile nezikwazi ukugaywa kabusha kanye nemishini yokukhiqiza elula.
✔ Isilinganiso esibanzi seyunithi ukusuka ku-0.10 kg kuya ku-500 kgs noma ngaphezulu kwalokho.
✔ Isakhiwo Esihlukahlukene kusuka ohlotsheni olulula kuya ohlotsheni oluyinkimbinkimbi.
✔ Ifanele izidingo zokukhiqiza zobuningi obuhlukahlukene.
5 - Iyiphi Insimbi & Ama-alloys Esakazwa I-Sand Casting Foundry Yakho?
Ngokuvamile izinsimbi eziningi eziyinsimbi nezingenayo i-ferrous zingaphonswa ngenqubo yokuphonsa isihlabathi. Okokusebenza okuyinsimbi,insimbi empunga, i-ductile cast iron, carbon steel,insimbi ye-alloy, insimbi yensimbi kanye neama-alloys ensimbi engagqwalizithelwa kakhulu. Ngezicelo ezingenayo insimbi, iningi le-Aluminium, iMagnesium,Ama-alloys asekelwe ethusinezinye izinto ezingezona insimbi zingaphonswa, kuyilaphoI-aluminium kanye ne-alloy yayoyizona ezisakazwa kabanzi ngokusakazwa kwesihlabathi.
6 - Ikuphi Ukubekezelela Kokusakaza Okungafezwa Ukulingisa Kwakho Kwesihlabathi?
Ukubekezelela ukusakaza kuhlukaniswe i-Dimensional Casting Tolerances (DCT) kanye ne-Geometrical Casting Tolerances (GCT). Isikhungo sethu singathanda ukukhuluma nawe uma unesicelo esikhethekile mayelana nokubekezelelana okudingekayo. Lapha okulandelayo yibanga lokubekezelelana elijwayelekile esingalifinyelela ngokwethuukuphonsa isihlabathi esiluhlaza, ukubunjwa kwesikhunta segobolondo kanye nokukhishwa kwesihlabathi se-furan resin:
✔ Ibanga le-DCT nge-Green Sand Casting: CTG10 ~ CTG13
✔ Ibanga le-DCT nge-Shell Mold Casting noma i-Furan Resin Sand Casting: CTG8 ~ CTG12
✔ Ibanga le-GCT nge-Green Sand Casting: CTG6 ~ CTG8
✔ Ibanga le-GCT nge-Shell Mold Casting noma i-Furan Resin Sand Casting: CTG4 ~ CTG7
7 - Yiziphi Isikhunta Sesanti?
Isikhunta sesihlabathi sisho izinhlelo zokubumba ezenziwe ngesihlabathi esiluhlaza noma isihlabathi esomile. Izinhlelo zokubumba zesihlabathi ikakhulukazi zimboza ibhokisi lesihlabathi, ama-spures, ama-inganites, izikhuphukeli, izinongo zesihlabathi, isihlabathi sesikhunta, ama-binders (uma zikhona), izinto eziphikisayo kanye nazo zonke ezinye izingxenye zesikhunta ezingaba khona.
