Camera isihlabathi igobolondo ekubunjweni e China inkampani ekubunjweni.
Ngesikhathi segobolondo isikhunta ekubunjweni, okokuqala kudingeka senze amaphethini ngokuya ngezidingo zamakhasimende nemidwebo, kanye nokucabangela isabelo sokulingisa. Ngaphambi kokwenza isikhunta sokuphonsa nomgogodla, isihlabathi esiboshwe simbozwe ngefilimu eqinile ye-resin ebusweni bezinhlayiya zesihlabathi. Isihlabathi esigcwele saziwa nangokuthi isihlabathi segobolondo (umgogodla). Inqubo yezobuchwepheshe ukuxuba ngomshini isihlahla se-phenolic se-powder esine-sand eluhlaza futhi uqinise lapho ushisa. Sekwenziwe waba yisihlabathi esigcotshisiwe ngokusebenzisa i-thermoplastic phenolic resin kanye ne-ejenti yokuphulukisa efihlekile (njenge-urotropine) ne-lubricant (efana ne-calcium stearate) ngenqubo ethile yokumboza. Lapho isihlabathi esinamakhaza sifudunyezwa, i-resin ifakwe ebusweni bezinhlayiya zesihlabathi ziyancibilika. Ngaphansi kwesenzo seqembu le-methylene elibolile yi-Maltropine, i-resin encibilikisiwe iguquka ngokushesha isuke esakhiweni esihambisanayo iye esakhiweni somzimba esingangeneki ukuze isihlabathi esiboshwe siqiniswe futhi sakheke. Ngaphezu kohlobo olujwayelekile oluyimbudumbudu olomile lwesihlabathi esigcwele, kukhona nesihlabathi esimanzi futhi esinombala obushelelezi.
Uma kuqhathaniswa nezinye isihlabathi resin, isihlabathi camera thusi has izici ezilandelayo
1) Inokusebenza kwamandla okufanelekile. Ingakwazi ukuhlangabezana nezidingo zensimbi eyigobolondo enamandla amakhulu, isihlabathi sebhokisi lamandla ashisayo, namandla aphansi non-ferrous alloy sand.
2) Uketshezi oluhle kakhulu, ukubumbana okuhle komgogodla wesihlabathi kanye nohlaka olucacile, olungakhiqiza izinhlamvu eziyisihlabathi eziyinkimbinkimbi kakhulu, ezinjengezinhlamvu zebhantshi lamanzi ezinjengezilinda zamasilinda nemizimba yomshini.
3) Izinga lobuso bengqamuzana lesihlabathi lihle, lihlangene futhi alikhululekanga. Noma kusetshenziswe ukumbozwa okuncane noma cha, ikhwalithi engaphezulu yokuphonsa ingatholakala. Ukunemba kobukhulu be-castings kungafinyelela ku-CT7-CT8, futhi ubukhulu be-Ra bungafinyelela ku-6.3-12.5μm.
I-4) Ukuhlangana okuhle, okulungele ukusakaza ukuhlanza nokwenza ngcono ukusebenza komkhiqizo
I-5) Umgogodla wesihlabathi akulula ukumunca umswakama, futhi namandla esitoreji sesikhathi eside akulula ukwehla, okulungele ukugcinwa, ukuthuthwa nokusetshenziswa
Izinqubo zokukhiqiza zesikhunta se-coated sand (umongo) wokwenza igobolondo ekubunjweni:
1. Inqubo eyisisekelo yokukhiqiza isikhunta sesihlabathi esigcotshisiwe (umongo) yile: flip noma igalelo lesihlabathi → uqweqwe → ukukhishwa kwesihlabathi → ukuqina → umongo (isikhunta) njalonjalo.
1) Phenduka noma ushaye isihlabathi. Okusho ukuthi, isihlabathi esigcotshisiwe sithelwa kusikhunta segobolondo noma sishaywe ebhokisini lomgogodla wokwenza igobolondo noma umongo wegobolondo.
2) Ukubethelwa. Ubukhulu besendlalelo segobolondo bulawulwa ngokulungisa ukushisa kokushisa nesikhathi sokubamba.
3) Ukukhishwa kwesihlabathi. Tshekisa isikhunta nebhokisi eliwumgogodla ukwenza isihlabathi esigaxekile esingasetshenziswanga siwe ebusweni begobolondo elifudumele, bese usiqoqa ukuze usisebenzise futhi. Ukuze kwenziwe kube lula ukususa isihlabathi esigcotshisiwe esingenakuncibilikiswa, uma kunesidingo, kungenziwa indlela yokunyakazisa emuva naphambili.
4) Ukuqina. Esimweni sokushisa, ukuze wenze ukushuba kwegobolondo kufane ngokwengeziwe, yenze ukuthi ixhumane nobuso begobolondo elifudumele esikhathini esithile ukuze kuqhubeke ukuqina.
5) Thatha umnyombo. Thatha ukwakheka kwegobolondo eliqinile nesisekelo segobolondo ngaphandle kwebhokisi lesikhunta kanye nomgogodla.
