Ukulingisa ukufaisetshenziswa kaningiinqubo yokubumba umjovo wensimbilokho kuhilela ukuthululela izinto ezigaywayo esibunjeni, ukusebenzisa ingcindezi yokubangela ukuba impahla ikhubazeke ngesikhathi sokucubungula okubandayo nokushisayo, bese kususwa okuphonswayo esibunjeni ukuze kwakheke umumo oyifunayo.
Ukuze kufezeke izimfuno zokukhiqiza ngobuningi, indlela yokufaka ukufa iwusizo ekwehliseni ukusetshenziswa kwezinto ezibonakalayo, ingase yehlise umjikelezo wokubumba, futhi umphumela wokubumba nokusebenza kuzinze kakhudlwana.
Ukukhiqizwa kwe-die casting kuncike ekwakhiweni kwesikhunta se-die casting, esinomthelela oqondile enqubweni yokuphonsa ukufa kanye nomphumela wokubumba. Idizayini efanele yesikhunta se-die casting inganikeza umkhiqizo ngokusebenza kahle, kuyilapho ukuklama okungalungile kungase kubangele isiphithiphithi senqubo nokulahlwa, kukhuphule izindleko zokukhiqiza nokuklama kabusha. Ukuze kuqinisekiswe ukuthi isikhunta sokuphonsa esifa sinokumelana okwanele kokugqoka, ukumelana ne-asidi ne-alkali, ukumelana nokugqwala, kanye nokubekwa uphawu okuhle kakhulu, ukuzinza okushisayo, nokunye ukusebenza okuhle kakhulu kokukhipha ukufa, umklamo wesikhunta sokufa kufanele ucabangele izinto ezisetshenziswayo, izindlela zokwelapha ukushisa, ukwakheka kwesikhunta, usayizi wesikhunta, imingcele yesikhunta, ukuhlanzeka kwendawo, nezinye izici.
Die casting isikhunta designkufanele isebenzise ikhompyutha ukulingisa okuguquguqukayo kwemizimba eminingi kanye nobuchwepheshe bokuhlaziya izinto ezinomkhawulo ukuze kuthuthukiswe idizayini kusetshenziswa indlela entsha, kuqhamuke ukuthuthukiswa komkhiqizo okusheshayo, kufinyeze umjikelezo wokuthuthukiswa, futhi kuthuthukise ikhwalithi yomkhiqizo.
Nakuba ukuklama okunembile kunikeza isisekelo esiqinile sokuphonswa kwezingxenye eziyinkimbinkimbi, kunezingozi ezihilelekile futhi, ngakho-ke ukuqaliswa kwesikhunta se-die casting kufanele kulungiswe ngokuqhubekayo ngokuhambisana nendawo yokusebenza yangempela.
Izici nobubanzi bezinhlelo zokusebenza zobuchwepheshe be-die casting
1.die casting izici zobuchwepheshe
Izici ezimbili eziyinhloko zenqubo yokubumba yokugcwalisa uketshezi noma i-semi-liquid yensimbi esetshenziswa ekubumbeni i-die cast, kanye nomehluko obalulekile phakathi kobuchwepheshe be-die casting kanye namanye amasu okuphonsa, ukucindezela okukhulu kanye nesivinini esikhulu.
2. Ukusetshenziswa kobuchwepheshe be-die casting
Enye yezindlela ezisezingeni eliphezulu kakhulu zokwakha insimbi i-die casting, futhi isebenza kahle ukukhiqiza izingxenye ezincipha kancane.
Njengamanje, ama-alloys asetshenziswa ekubunjweni kokufa akhula kancane kancane ukuze akhiphe izinto ngaphandle nje kwe-zinc, i-aluminium, i-magnesium, ne-alloys yethusi.
Ama-Die castings enziwe ngama-alloys ensimbi njengensimbi nensimbi.
Die casting isikhunta impahla
Ngokusho kohlobo lwensimbi okufanele lucutshungulwe, ubukhulu bomthwalo, ukusetshenziswa kwezinga lokushisa kanye nesivinini sokwenza, izidingo ezihlukene zibekwe phambili ukuze zikhethe izinhlobo ezahlukene zensimbi eshisayo yokusebenza. I-ω (c) yensimbi yensimbi eshisayo ngokuvamile ingu-0.3 ~ 0.6%, lapho okuqukethwe kwekhabhoni kuphezulu kakhulu, ukuqina kanye nepulasitiki yokwehla kwensimbi, kanye ne-thermal conductivity impofu; Uma okuqukethwe kwekhabhoni kuphansi kakhulu, ubulukhuni nokumelana nokugqoka akukwazi ukuhlangabezana nezidingo.
Hot umsebenzi die steel ngokuvamile wengeze Cr, Mn, Ni, Si nezinye izakhi ukuqinisa matrix ferritic, ngcono amandla ukuqina ukuqina futhi ukuqina kwensimbi, Ningakwazi futhi ngcono ezishisayo ukumelana ukukhathala, ukuze ucwenge okusanhlamvu ukuthuthukisa amandla nobulukhuni, tempering ukuzinza, ukuvimbela tempering brittleness, kodwa futhi wengeze Ni, Mo, V kanye nezinye izakhi. Ngaphezu kwalokho, i-Ni, i-Mo, i-V kanye nezinye izakhi zenziwa ngendlela ye-carbide ngesikhathi sokushisa ukukhiqiza ukuqina kwesibili, ukuze umsebenzi oshisayo ufe insimbi usengakwazi ukugcina amandla aphezulu ekushiseni okuphezulu.
Isikhunta se-aluminium
Ngokuminyana kwayo okuphansi namandla ayo aphezulu, ingxubevange ye-aluminium iya ngokuya iduma. Ngemuva kokuthi ukwakheka kwawo kwamakhemikhali sekuthuthukisiwe,ukufakwa kwe-aluminium, i-hot extrusion, nezinqubo zokuguga zokwenziwa zasetshenziswa ukuze kuthuthukiswe ukusebenza kwayo. Imikhiqizo eyenziwe nge-aluminium alloy die-casting isetshenziswa ngokuyinhloko kuma-electronics, ezezimoto, izinto zikagesi zasendlini, zezimoto, nakwezinye izimboni zokuxhumana. Izindiza ezinkulu, imikhumbi, nezinye izimboni ezinezidingo eziphezulu zobuchwepheshe nazo zisebenzisa ezinye zekhwalithi ephezulu ze-aluminium alloy ezisebenza kahle, ukunemba okuphezulu, nokuqina okuphezulu, nakuba ukusetshenziswa kwazo okuyinhloko kusezingxenyeni ezithile zemishini.
I-aluminium alloy die casting technique iphakeme kunobuchwepheshe obujwayelekile bokwenza ingxubevange ye-aluminium ngezindlela ezilandelayo: izinhlobonhlobo ezinkulu ze-die cast; Ukuzinza okuhle kancane kancane kanye nokunemba okuphezulu kwe-dimensional; Amandla okulingisa, ubulukhuni bobuso obuphezulu, ubulukhuni obuphansi, ukukhiqiza okuphezulu, izinga eliphezulu lokusetshenziswa kwensimbi, nokunye.
Ithrendi yokuthuthuka yedizayini yethuluzi lokusakaza ngefa
Idizayini yesikhunta kufanele icabangele izimfuno ezicindezelayo zomsebenzisi zokulethwa okusheshayo, ukunemba okuphezulu, kanye nokwakhiwa kwesikhunta okuthengekayo.
Amathrendi alandelayo okukhula ayoba khona nakanjani:
1.Idizayini yesikhunta ukusuka esigabeni somqondo ukuya esiqondisweni sokuhlaziywa kwethiyori kanye nomklamo osizwa yikhompyutha.
Ibhizinisi lesikhunta lisebenzisa kakhulu ubuchwepheshe be-CAD/CAM/CAE, obuthuthukisa kakhulu umthwalo wesikhunta futhi lwenza ukwakhiwa kwesikhunta kube okunengqondo nesayensi.
2.Ukunemba, ukwakheka kwesikhunta esisheshayo kanye nenqubo yokukhiqiza, kanye nomjikelezo wokukhiqiza umkhiqizo omfushane.
3.Imboni ye-CAD/CAE/CAM iqhubekela phambili ekuhlanganiseni, ezinhlangothini ezintathu, kwezobuhlakani, nasekuxhumekeni kwenethiwekhi.
4. Isikhunta siguqukela ohlangothini lokunemba, ubunkimbinkimbi, kanye nesilinganiso esikhulu; Ubuchwepheshe obusekelwe kulwazi lobunjiniyela (KBE). 5.ukwenyusa izinga lokumiswa kwesikhunta kanye nezinga lokusetshenziswa kokulinganisa kwesikhunta.
Ningbo Jiehuang die casting isikhunta umenzi Isikhunta esiphezulu se-die-casting-mold, inkampani ye-Ningbo jiehuang die casting iyathuthuka ngendlela yobuhlakani. Ucwaningo nokuthuthukiswa kwezinto ezintsha zokulingisa ukuze kuhlangatshezwane nezidingo zenqubekelaphambili yobuchwepheshe bezimboni. Ucwaningo nokuthuthukiswa kwemishini emisha yokusakaza, ukuthuthukisa izinga lokuzenzekelayo, ukuthuthukiswa kobuchwepheshe obusha bokubona. Thuthukisa ubuchwepheshe obusha bokuphonsa, uthuthukise futhi ukhuphule izinga lenqubo yokufa, ukhuphule impilo yokufa, unciphise izindleko zokukhiqiza, ukuxazulula inkinga yokusakazwa kwensimbi emnyama.
