Ukucocwa kokuphosa yinkqubo ebalulekileyo ekwenzeni izinto zentsimbi, ngakumbi kumashishini afana neemoto, i-aerospace, kunye noomatshini abanzima. Emva kokuba isinyithi siphoswe, imveliso ephumayo, eyaziwa ngokuba yi-casting, ihlala ifuna ukuqhutyelwa phambili ukususa izinto ezingaphezulu, ukungafezeki komphezulu, kunye nezinye iintsalela ezingafunekiyo. Le nkqubo iqinisekisa ukuba imveliso yokugqibela ihlangabezana neenkcukacha ezifunekayo kunye nemigangatho yomgangatho.
Iindlela zokuCasa ukuCoca
1. Ukucoca oomatshini:
Ukudutyulwa: Le yeyona ndlela ixhaphakileyo, apho amasuntswana abrasive (ukudubula) aqhutywa ngesantya esiphezulu ukususa isikali somphezulu, isanti, kunye nezinye iintsalela ekugalweni. Isebenza kakhulu ekucoceni isinyithi kunye neentsimbi ezingezizo i-ferrous. Ukudutyulwa kudla ngokusetyenziswa kwiutyalo maliukucoca iimilo eziyinkimbinkimbi zokuphosa, ngakumbi ezo zinezakhiwo zangaphakathi ezinzima ezinzima ukuzicoca ngezinye iindlela.
Ukusila: Ukusila kuquka ukusebenzisa ivili lokusila okanye ibhanti elirhabaxa ukuze kususwe izinto ezigqithisileyo, ezifana neflash okanye amaphiko, kunye nokulungisa izinto ezingahambi kakuhle. Le ndlela isetyenziswa ngokuqhelekileyo kumsebenzi wokugqiba oneenkcukacha.
UkuQeda kweVibratory: Kule nkqubo, i-castings ifakwe kwi-vibratory machine ezaliswe yi-media abrasive. I-vibration ibangela ukuba i-media ikhuhle ngokuchasene ne-castings, ipholise kwaye isuse nayiphi na i-particle okanye i-burrs. Le ndlela ifanelekile kwinxalenye encinci ukuya kwephakathi.
2. Ukucoca ngemichiza:
Ukuvunwa: Ukuchola kubandakanya ukuntywiliselwa ukugalela kwisisombululo seasidi ukususa iioksidi ezingaphezulu kunye nokungcola. Le ndlela iluncedo kakhulu kwintsimbi engenasici kunye nezinye iintsimbi ezingenayo i-ferrous. Nangona kunjalo, ifuna ukuphathwa ngononophelo ngenxa yendalo eyingozi yeekhemikhali ezibandakanyekayo.
Electropolishing: Le yinkqubo ye-electrochemical egudileyo kwaye ihlambulule umphezulu we-casting ngokususa uluhlu oluncinci lwesinyithi. Ihlala isetyenziselwa amacandelo afuna iqondo eliphezulu lokucoceka kunye nokugqiba okufana nesipili, njengazo zisetyenziselwa ukusetyenziswa kwezonyango okanye ukutya.
3. Ukucoca iThermal:
Ukutshisa: Ngale ndlela, iicastings ziboniswa kubushushu obuphezulu kwiziko ukutshisa nayiphi na intsalela yesanti, iicores, okanye izibophelelo. Oku kusebenza ngokukodwa kwiipaseji ezineepaseji ezintsonkothileyo zangaphakathi, apho ukucoca ngoomatshini kunokuba nzima.
Izicelo kunye nokufaneleka
IimotoUmzi-mveliso: Ukudubula nokusila kusetyenziswa rhoqo ukucoca iibhloko ze-injini, iintloko ze-cylinder, kunye nezinye izinto ezinkulu.
Umzi-mveliso we-aerospace: Iindlela zokucoca iikhemikhali ezinje nge-electropolishing zikhethwa kumalungu afuna iqondo eliphezulu lokuchaneka kunye nokugqiba komphezulu, okufana neeblawudi ze-iturbine kunye nezinye iindawo ezibalulekileyo.
Oomatshini abanzima: Ukugqibezela ukungcangcazela kunye nokudutyulwa kokudubula ngokuqhelekileyo kusetyenziselwa ukucoca kunye nokuchithwa kwezinto ezinkulu ezisetyenziselwa izixhobo ezinzima kunye noomatshini.
Ukuqukumbela
Ukukhetha indlela efanelekileyo yokucoca i-casting kuxhomekeke kwizinto zokuphosa, ubunzima benxalenye, kunye nokugqiba okufunwayo kwendawo. Ukucoca ngokufanelekileyo kubalulekile ekuqinisekiseni ukuba ukuphosa kuhlangabezana neemfuno zokusebenza kunye nobuhle, okwenza kube linyathelo elibalulekileyo kwinkqubo yokuvelisa ngokubanzi.
