Izindlela zobuchwepheshe zokucubungula izingxenye ze-aluminium alloy
1) Ukukhethwa kokucubungula idatha
Idatha yokucubungula kufanele ihambisane ngangokunokwenzeka nedatha yokuklama, i-datum yokuhlanganiswa kanye nedatha yokulinganisa, futhi ukuzinza, ukunemba kokuma nokuthembeka kwesakhiwo sezingxenye kufanele kucatshangelwe ngokugcwele kubuchwepheshe bokucubungula.
2) Ukwenza imishini enzima
Ngenxa yokuthi ukunemba kwe-dimensional kanye nobukhulu obungaphezulu kwezinye izingxenye ze-aluminium alloy akulula ukuhlangabezana nezidingo zokunemba okuphezulu, ezinye izingxenye ezinobunjwa obuyinkimbinkimbi zidinga ukuguqulwa ngaphambi kokucubungula, futhi zihlanganiswe nezici ze-aluminium alloy materials zokusika. Ukushisa okukhiqizwa ngale ndlela kuzoholela ekusikeni kokuguqulwa, amazinga ephutha ahlukahlukene ngobukhulu bezingxenye, futhi kuholele ngisho nasekuguqukeni kwe-workpiece. Ngakho-ke, ngenxa yokucubungula indiza evamile yokugaya. Ngesikhathi esifanayo, uketshezi olupholile lwengezwa ukupholisa umsebenzi wokunciphisa ithonya lokusika ukushisa ekunembeni komshini.
3) Qedela ukukhanda
Emjikelezweni wokucubungula, ukusika ngesivinini esikhulu kuzokhiqiza ukushisa okuningi kokusika, nakuba imfucumfucu ingathatha ukushisa okukhulu, kodwa noma kunjalo ingakhiqiza izinga lokushisa eliphakeme kakhulu ku-blade, ngoba i-aluminium alloy melting point iphansi, i-blade. ivamise ukuba sesimweni sokuncibilika, ukuze amandla ephoyinti lokusika athintwe izinga lokushisa eliphezulu, kulula ukukhiqiza izingxenye ze-aluminium ingxubevange ngesikhathi sokwenza ukukhubazeka kwe-concave kanye ne-convex. Ngakho-ke, ekuqedeni inqubo, ngokuvamile khetha uketshezi lokusika ngokusebenza okuhle kokupholisa, ukusebenza kahle kokugcoba kanye ne-viscosity ephansi. Lapho amathuluzi okugcoba, ukushisa okusika kuthathwa ngesikhathi ukuze kuncishiswe izinga lokushisa elingaphezulu lamathuluzi nezingxenye.
4) Ukukhetha okunengqondo kwamathuluzi okusika
Uma kuqhathaniswa nezinsimbi ezisansimbi, amandla okusika akhiqizwa i-aluminium alloy mancane uma kuqhathaniswa nenqubo yokusika, futhi isivinini sokusika singaba phezulu, kodwa kulula ukwenza ama-nodule emfucumfucu. I-thermal conductivity ye-aluminium alloy iphezulu kakhulu, ngoba ukushisa kwemfucumfucu kanye nezingxenye zenqubo yokusika kuphakeme, izinga lokushisa lendawo yokusika liphansi, ukuqina kwethuluzi kuphakeme, kodwa ukuphakama kwezinga lokushisa kwezingxenye ngokwazo. kuyashesha, kulula ukubangela ukubola. Ngakho-ke, kuphumelela kakhulu ukunciphisa amandla okusika kanye nokusika ukushisa ngokukhetha ithuluzi elifanele kanye ne-angle yamathuluzi enengqondo kanye nokuthuthukisa ubulukhuni bendawo yamathuluzi.
5) Sebenzisa ukwelashwa ukushisa kanye nokwelashwa okubandayo ukuxazulula ukuguqulwa kokucubungula
Izindlela zokwelapha ukushisa ukuze kuqedwe ukucindezeleka komshini wezinto ze-aluminium alloy zihlanganisa: isikhathi sokufakelwa, i-recrystallization annealing, njll. Umzila wenqubo wezingxenye ezinesakhiwo esilula uvame ukutholwa: umshini onzima, ukufika kwesikhathi ngesandla, ukuqeda imishini. Ngomzila wenqubo wezingxenye ezinesakhiwo esiyinkimbinkimbi, ngokuvamile isetshenziswa: umshini onzima, ukuhambisana nesikhathi okwenziwayo (ukwelashwa kokushisa), umshini wokuqeda, ukuhambisana nesikhathi okwenziwayo (ukwelashwa kokushisa), ukuqeda imishini. Ngenkathi inqubo yokwenziwa ngesikhathi (ukwelashwa kokushisa) ihlelwa ngemva komshini onzima kanye nokuqeda ingxenye, inqubo yokwelapha ukushisa okuzinzile ingahlelwa ngemva kokuqeda umshini ukuze kuvinjelwe ukuguqulwa kosayizi omncane ngesikhathi sokubekwa kwezingxenye, ukufakwa nokusetshenziswa.
Izici zenqubo yokucubungula izingxenye ze-aluminium alloy
I-1) Inganciphisa ithonya lokucindezeleka okusalayo ekuguqulweni komshini.Ngemuva komshini onzima, kuphakanyiswa ukuthi kusetshenziswe ukwelashwa kokushisa ukuze kususwe ingcindezi ekhiqizwa imishini enzima, ukuze kwehliswe umthelela wengcindezi kukhwalithi yokuqeda imishini.
2) Thuthukisa ukunemba kwemishini kanye nekhwalithi ephezulu.Ngemuva kokuhlukaniswa kwemishini enzima nokuqeda, ukuqeda imishini kunesabelo esincane sokucubungula, ukucubungula ukucindezeleka nokuguqulwa, okungathuthukisa kakhulu izinga lezingxenye.
3) Thuthukisa ukusebenza kahle kokukhiqiza.Njengoba umshini onzima ususa kuphela izinto ezithe xaxa, ushiya umkhawulo owanele wokuqeda, awucabangi usayizi nokubekezelelana, okunikeza ngempumelelo ukudlala ekusebenzeni kwezinhlobo ezahlukene zamathuluzi omshini nokuthuthukisa ukusebenza kahle kokusika.
Ngemuva kokuthi izingxenye ze-aluminium alloy zisikiwe, isakhiwo sensimbi sizoshintshwa kakhulu. Ngaphezu kwalokho, umphumela wokusika ukunyakaza kuholela ekucindezelekeni okukhulu okusalayo. Ukuze unciphise ukuguqulwa kwezingxenye, ukucindezeleka okusala kwezinto kufanele kukhululwe ngokugcwele.
