I-high pressure die casting iyindlela eyenza insimbi ewuketshezi noma i-semi-liquid igcwalise imbobo yesikhunta se-die casting ngesivinini esikhulu ngokucindezela okukhulu, futhi amafomu futhi aqinise ngaphansi kwengcindezi ukuze athole ukukhishwa.
I-1.Inqubo yokukhipha ingcindezi ephezulu
1.1
Njengamanje, isiqhingi esivamile sokusakaza i-die-casting sizocabangela ukucushwa okulandelayo; Umshini wokufafaza nge-vacuum, isithando somlilo sokugcina ukushisa sifakwe uhlelo lokuphonsa oluningi, umkhiqizo onohlobo lwesistimu yokufafaza, unciphise isikhathi sokufafaza, irobhothi ukuthatha izingxenye, isikhwama se-slag, ukusika ikhodi kanye nomunye umsebenzi, ukusika kokugcina uhlelo lwesango; Isiqhingi se-die-casting singathuthukiswa ukuze sihlanzeke ngokuzenzakalelayo ngaphansi kwezimo zevolumu ephezulu.
1.2
Ukuhlaziywa kwe-CAE kusetshenziswe kabanzi embonini ye-die casting, emele i-PROCAST, MAGMA, flow-3D, njll Ngokusho kwemiphumela yokubala yokugcwalisa ukugeleza nokusabalalisa kwesivinini, ukulingisa kungabikezela ngokunembile iziphambeko ezifana nokubhalisa, ukufakwa kanye ukugcwaliswa okubi, okuthuthukisa kakhulu isivuno futhi konga izindleko ezinenjongo kakhulu. Kuyithuluzi eliwusizo kakhulu lokuklama ngokushesha nangokwesayensi lonke uhlelo lokuphonsa (isango, i-sprue kanye nethangi elichichimayo, njll.) lokuphonsa ukufa. Lungiselela amapharamitha wenqubo yokukhipha, wehlise inani lokuhlolwa kwesikhunta, wehlise izindleko zokuphonsa, uthuthukise ikhwalithi yomkhiqizo. Isoftware ye-CAE isetshenziselwe ukuhlaziywa okujwayelekile kokugcwalisa, ukuqinisa, ukusatshalaliswa kwe-porosity kanye nemibiko yokusabalalisa isivinini
1.3 Ukufakwa kwe-vacuum die casting
Ngokuhlinzekwa okuqhubekayo kwezidingo zekhwalithi yomkhiqizo, ukusetshenziswa kwe-vacuum ukuxazulula inkinga yokugcwalisa kanye nokuqina komoya kwe-castings kuye kwathuthukiswa kahle, futhi i-vacuum valve isetshenziswa ngokuvamile, i-vacuum valve esetshenziswa kakhulu inezakhiwo ezimbili ezilandelayo. Umfanekiso wesi-3 wumdwebo wohlelo lwevalvu yevacuum. Njengenqubo evamile yokukhipha ukufa, ngemva kokuba amanzi e-aluminium engena ekamelweni, ukuhlanza kuqala ukuqala. Khona-ke, lapho umshini wokujikijela ifa uqala ngesivinini esikhulu, amandla e-kinetic wamanzi e-aluminium kuthenjelwa kuwo ukuthinta ipuleti lasentwasahlobo le-vacuum valve. Uma usebenzisa i-vacuum valve engumshini, ngokuvamile ivalwa lapho kushisa isikhunta. Uma ukushisisa kuqala sekuphelile, i-vacuum valve ingasetshenziswa kuphela uma isivinini esikhulu kanye nokucindezela kuqalwa. I-vacuum valve inezinzuzo zokusebenzisa okulula, kodwa ukunemba kokucubungula kwe-vacuum valve kuphezulu, futhi izindleko ze-vacuum valve ziphakeme kakhulu. Umfanekiso wesi-4 wumdwebo wohlelo lwevalvu ye-vacuum ye-hydraulic. Umgomo we-vacuum valve wemishini uyafana. Lapho i-punch iqala, i-vacuum iqala, kodwa isimiso sokuvala i-vacuum valve sihlukile. Lapho i-valve ye-vacuum ye-hydraulic ngokuvamile iqalwa ngesivinini esikhulu, uhlobo luthunyelwa ohlelweni lwe-hydraulic ye-vacuum valve ngesikhathi esifanayo, futhi i-vacuum valve ivaliwe. Izindleko ze-vacuum valve ye-hydraulic ziphansi uma kuqhathaniswa, kodwa zidinga ukuthi imingcele yenqubo yokukhipha ukufa kanye nomklamo wesikhunta kufanele kufane, ngaphandle kwalokho amanzi e-aluminium ashona e-vacuum valve azobangela ukuvinjelwa.
2.Ukulingisa
Njengamanje, imikhiqizo ye-aluminium alloy die casting ihlukaniswe izigaba ezintathu ngokuya ngenani. Isigaba sokuqala yimoto, isithuthuthu, igobolondo lokudlulisa injini elimelwe injini yenjini, isilinda somzimba nokunye. Uhlobo lwesibili igobolondo lesiteshi sesisekelo kanye negobolondo lesihlungi elimelwe ukuxhumana kwenethiwekhi, futhi uhlobo lwesithathu ukwakheka komzimba okunezidingo eziphezulu zokusebenza kwemishini. Njengoba kuboniswe emfanekisweni, kuwumkhiqizo ojwayelekile we-aluminium alloy die casting:
3.Isiphetho
I-aluminium alloy inamandla athile aphezulu kanye nokumelana nokugqwala okuhle, ukuhanjiswa kukagesi okuhle kakhulu. Ngaphansi kwemvelo yenhlalo yokonga amandla kanye nokuncishiswa kokungcola kanye nokuvikelwa kwemvelo okuluhlaza, i-aluminium alloy die casting ithuthuke ngokushesha e-China. Ngikholelwa ukuthi esikhathini esizayo esiseduze, imikhiqizo ye-aluminium alloy izohluka kakhulu. I-deformation eyinhloko ikulezi zici ezilandelayo; I-1) Ngokuthuthukiswa kwemikhiqizo, izothuthukisa ukuthuthukiswa kwezinto ezintsha ze-aluminium alloy alloy, njenge: conductivity ephezulu ye-thermal, amandla aphezulu kanye nesiqondiso sokuqina okuphezulu; 2) izinto ezintsha zokuphonsa i-aluminium alloy nazo zizothuthukisa ukuthuthukiswa kobuchwepheshe obusha bokufa, njengenqubo yokufaka i-semi-solid die casting, i-high vacuum suction casting 3) ukuthuthukiswa kobuchwepheshe kuzonikeza imishini, izinto ezisizayo zibeka izidingo eziphezulu. , njengokuthi: umshini wokufafaza omkhulu, umshini wokushisa we-die, imishini yokufafaza, ukukhipha isikhunta umshini ofanayo, umshini we-vacuum, umshini obandayo, ukulawulwa kwezinga lokushisa kwesikhunta kanye nesistimu yokuthola, njll.
