Ukucheba yinkqubo eqhelekileyo ekuvelisweni kweemveliso zerabha. Iindlela zokucheba ziquka ukucheba ngesandla, ukugawula, ukusika, ukucheba i-cryogenic, kunye nokwenza i-mold engenakukhanya, phakathi kwezinye. Abavelisi banokukhetha indlela efanelekileyo yokucheba ngokusekelwe kwiimfuno zomgangatho weemveliso kunye neemeko zabo zemveliso.
Ukucheba ngesandla
Ukusika ngesandla yindlela yakudala yokusika, equka ukubhoboza nokusika umphetho ngerabha ngesandla usebenzisa izikrufu, izikere, kunye nezixhobo zokukrwela. Umgangatho kunye nesantya seemveliso zerabha ezisikiweyo ngesandla zinokuhluka kumntu nomntu. Kufuneka ukuba ubukhulu bejometri yeemveliso emva kokusika kufuneka buhlangabezane neemfuno zemizobo yemveliso, kwaye akufuneki kubekho imikrwelo, ukusikwa, okanye ukuguguleka. Ngaphambi kokusika, kuyimfuneko ukuqonda ngokucacileyo indawo yokusika kunye neemfuno zobugcisa, kunye nokuqonda iindlela zokusika ezichanekileyo kunye nokusetyenziswa ngokufanelekileyo kwezixhobo.
Kwimveliso yezixhobo zerabha, uninzi lwemisebenzi yokucheba yenziwa ngeendlela ezahlukeneyo zokusebenza ngezandla. Ngenxa yokusebenza okuphantsi kwemveliso yemisebenzi yokucheba ngesandla, kudla ngokuba yimfuneko ukuhlanganisa abantu abaninzi ukuze bachebe, ingakumbi xa imisebenzi yemveliso ixinene. Oku akuchaphazeli nje kuphela umyalelo womsebenzi kodwa kukwabeka emngciphekweni umgangatho weemveliso.
Ukucheba ngoomatshini
Ukusika ngoomatshini kubandakanya ukubhoboza, ukugaya ngevili lokusila, kunye nokusika i-circular blade, ezifanelekileyo kwiimveliso ezithile ezineemfuno eziphantsi zokuchaneka. Okwangoku yindlela yokusika ephucukileyo.
1) Ukucheba ngoomatshini kubandakanya ukusebenzisa umatshini wokucinezela kunye ne-punch okanye i-die ukususa umphetho werabha yemveliso. Le ndlela ifanelekile kwiimveliso kunye nemiphetho yazo yerabha enokubekwa kwipleyiti yesiseko se-punch okanye i-die, njengezithinteli zebhotile, izitya zerabha, njl. Kwiimveliso ezinomxholo werabha ophezulu kunye nobunzima obuphantsi, indlela yempembelelo idla ngokusetyenziselwa ukusika imiphetho, enokunciphisa ukungalingani kunye nokudodobala kumphezulu osecaleni okubangelwa kukuqina kwemveliso emva kokusikwa. Kwiimveliso ezinomxholo werabha ophantsi kunye nobunzima obuphezulu, indlela yokusebenzisa isikhunta somphetho wokusika inokusetyenziswa ngokuthe ngqo. Ukongeza, ukucheba kunokwahlulwa kube kukucheba okubandayo kunye nokucheba okushushu. Ukucheba okubandayo kubhekisa ekuchebeni kubushushu begumbi, okufuna uxinzelelo oluphezulu lokucheba kunye nomgangatho ongcono wokucheba. Ukucheba okushushu kubhekisa ekuchebeni kubushushu obuphezulu, kwaye kuyimfuneko ukuphepha ukunxibelelana ixesha elide nemveliso kumaqondo obushushu aphezulu, okunokuchaphazela umgangatho wemveliso.
2) Ukusika ngoomatshini kufanelekile ekuchebeni iimveliso ezinkulu kwaye kusetyenziswa izixhobo zokusika. Umatshini ngamnye wokusika ngumatshini okhethekileyo, kwaye iimveliso ezahlukeneyo zisebenzisa izixhobo zokusika ezahlukeneyo. Umzekelo, emva kokuba itayara ivulcanized, kukho imicu yerabha enobude obahlukeneyo kwiindawo zokukhupha umoya kunye nemigca yokukhupha umoya yetayara, ekufuneka isuswe kusetyenziswa isixhobo esinemiqolo ngelixa itayara ijikeleza.
3) Ukusika ngoomatshini kusetyenziswa kwiimveliso zerabha ezinemingxunya yangaphakathi nezangqa zangaphandle, kwaye ukugaya kudla ngokusetyenziswa. Isixhobo sokugaya sisivili sokusika esinobukhulu obuthile besuntswana, kwaye ukuchaneka kokusika ngoomatshini kuphantsi, nto leyo ebangela ukuba kubekho umphezulu orhabaxa kunye namasuntswana entlabathi aseleyo, nto leyo enokuchaphazela isiphumo sokusetyenziswa.
4) I-Cryogenic deflashing isetyenziselwa iimveliso ezichanekileyo ezineemfuno eziphezulu zokusika, ezifana nee-O-rings, izitya zerabha ezincinci, njl. Le ndlela ibandakanya ukupholisa imveliso ngokukhawuleza ukuya kubushushu obubuthathaka kusetyenziswa i-nitrogen engamanzi okanye umkhenkce owomileyo, uze emva koko ufake ngokukhawuleza iipellets zesinyithi okanye zeplastiki ukuze kwaphulwe kwaye kususwe i-flash, kugqitywe inkqubo yokusika.
5) Ukucheba iibhrashi ngobushushu obuphantsi: Kubandakanya ukusebenzisa iibhrashi ezimbini zenylon ezijikeleza i-axis ethe tye ukushenxisa umphetho werabha weemveliso zerabha ezikhenkcezisiweyo.
6) Ukusika idrama ngobushushu obuphantsi: Le yindlela yokuqala yokusika i-cryogenic, kusetyenziswa amandla okuchaphazela adalwa yidrama ejikelezayo kunye nokungqubana phakathi kweemveliso ukuze kuqhekeke kwaye kususwe i-flash kwiimveliso ezikhenkcezisiweyo ngaphantsi kobushushu obungaphantsi kobushushu obuqhelekileyo. Imilo yedrama idla ngokuba yi-octagonal ukwandisa amandla okuchaphazela kwiimveliso ezikwidrama. Isantya sedrama kufuneka sibe phakathi, kwaye ukongezwa kwe-abrasives kunokuphucula ukusebenza kakuhle. Umzekelo, indlela yokusika umphetho weeplagi zerabha zee-capacitors ze-electrolytic isebenzisa ukusika idrama ngobushushu obuphantsi.
7) Ukusika okuguquguqukayo okuphantsi kobushushu, okwaziwa ngokuba kukusika okujikelezayo okujikelezayo: Iimveliso ziyajikeleza kwipatheni ejikelezayo kwibhokisi yokutywina ejikelezayo, nto leyo ebangela impembelelo enamandla phakathi kweemveliso naphakathi kweemveliso kunye ne-abrasive, nto leyo ebangela ukuba i-flash eqandisiweyo iwe. Ukusika okuguquguqukayo okuphantsi kobushushu kungcono kunokusika iidrum eziphantsi kobushushu, kunye namazinga omonakalo aphantsi kwimveliso kunye nokusebenza kakuhle kwemveliso.
8) Ukucheba nokungcangcazela okuphantsi kobushushu: Ifanelekile kwiimveliso ezincinci okanye ezincinci okanye iimveliso zerabha ze-micro silicone ezityebileyo kwi-skeletons zesinyithi. Isetyenziswa kunye ne-abrasives ukususa i-flash kwimingxunya yemveliso, iikona, kunye nee-grooves.
Umatshini wokucoca ulwelo i-Cryogenic
Umatshini okhethekileyo wokucoca i-cryogenic ususa ii-burrs ngokusebenzisa i-nitrogen engamanzi ukwenza imiphetho yemveliso egqityiweyo ibe buthathaka kumaqondo obushushu aphantsi. Usebenzisa amasuntswana athile aqandisiweyo (ii-pellets) ukususa ngokukhawuleza ii-burrs. Umatshini wokusika imiphetho eqandisiweyo usebenza kakuhle kakhulu, unamandla aphantsi okusebenza, umgangatho wokusika olungileyo, kunye nenqanaba eliphezulu lokuzenzekela, okwenza ukuba ufaneleke ngakumbi kwiindawo zerabha ezicocekileyo. Usebenza kakhulu kwaye uye waba ngumgangatho wenkqubo eqhelekileyo, ufanelekile ukususa ii-burrs kwiindawo ezahlukeneyo zerabha, i-silicone, kunye ne-zinc-magnesium-aluminium alloy.
Isikhunta esingenamthungo
Ukusebenzisa ii-burrless molds kwimveliso kwenza umsebenzi wokusika ube lula kwaye ube lula (ii-burrs zingasuswa ngokulula ngokukrazula, ngoko ke olu hlobo lwe-mold lubizwa ngokuba yi-drain-off mold). Indlela yokwenza i-burrless mold iyisusa ngokupheleleyo inkqubo yokusika, iphucula umgangatho wemveliso kunye nokusebenza, inciphisa amandla abasebenzi, kunye neendleko zemveliso. Inamathuba abanzi ophuhliso kodwa ayifanelekanga kubavelisi abaneemveliso eziguquguqukayo nezihlukeneyo.
