Ukuziphatha Okucindezelayo Okushisayo Kwe-Die-Cast AZ91D Magnesium Alloy

Ngenxa yezakhiwo zayo ezihlukile, ukuqashelwa kwama-magnesium alloys embonini kuyaqhubeka nokwanda, nobubanzi besicelo buyakhula. Njengamanje, inqubo eyinhloko yokwakha i-magnesium alloy is die-casting. Ekukhiqizweni kwangempela, ngenxa yezidingo zezimo zokusebenza noma inqubo yenqubo, imvamisa kuyadingeka ukwenza imishini engaphelele noma ephelele yeplastiki ye-magnesium alloy die castings. Ngasikhathi sinye, ukucutshungulwa kwepulasitiki kokufa kungasusa ukuncipha kanye ne-porosity ebangelwe inqubo yokufa. , Thuthukisa izakhiwo eziphelele zezinto ezibonakalayo. Kodwa-ke, ama-alloys we-magnesium ane-plastic encane futhi kunzima ukwenza imishini yeplastiki ekamelweni lokushisa; Ama-alloys e-die-cast magnesium kunzima kakhulu ukwenza imishini yepulasitiki ekamelweni lokushisa ngenxa yokuba khona kwenani elikhulu lezigaba ezincibilika kancane kunethiwekhi emingceleni yezinhlamvu, futhi ngokuvamile zidinga imishini ye-thermoplastic. Lokhu kukhawulela ukwandiswa nokusetshenziswa kwama-magnesium alloys ngezinga elithile.

Eminyakeni yamuva nje, kube nezifundo eziningi mayelana nokuziphendukela kokuziphatha kwama-alloys we-magnesium njenge-AZ31, AZ61, ne-AZ91 (state-die-cast state), kepha kunemibiko embalwa ngokuziphatha kwe-deformation kwe-die-cast AZ91D magnesium alloy, ikakhulukazi ukushisa kwe-deformation. Ukuphendula lezi zinkinga ezingenhla, leli phepha lisebenzisa i-Geeble-1500D thermal simulator ukwenza isivivinyo esishisayo se-compression deformation ku-die-cast AZ91D magnesium alloy ngaphansi kwezimo zesilinganiso sobunzima se-0.01 ~ 10s -1 kanye ne-deformation temperature of 50 ~ 450℃ ukutadisha isimilo sayo se-Thermal compression deformation; ngasikhathi sinye, kwafundwa ukwakhiwa kwe-microstructure.

Umsebenzi wokucwaninga oyinhloko kanye nemiphumela yale mqondo ngokulandelayo:

1. Hlaziya uphinde ucubungule idatha efanele etholwe ekuhlolweni kokucindezela okushisayo, bese uthola ijika le-die-cast AZ91D magnesium alloy rheological; sungula i-high-temperature plastic deformation constitutive equation echazwe imingcele ye-Zener-Hollomom njenge-έ = 1.41 × 10 12 [sinh (0.014 σ)] 5.295 exp (-159449.509 / RT), kusetshenziswa umsebenzi we-hyperbolic sine ukuthola amandla wokuvula amandla we-deformation okokusebenza Q = 159.45kJ · mol -1, uma kuqhathaniswa namandla adonsela phansi e-AZ91D magnesium alloy, ukugeleza kwawo ukucindezela nokusebenza kwe-deformation Amandla aphansi angabangelwa umehluko osobala phakathi kwesimo sokudonsa amandla adonsela phansi kanye nesimo sokuphonsa inqubo yokulingisa.
2. Ngokusho kombono wemodeli yempahla enamandla kanye nomdwebo wokumaketha, umdwebo wokuqothula amandla, umdwebo wokungazinzi kanye nomdwebo wokumaketha we-die-cast AZ91D magnesium alloy wenziwa kusetshenziswa idatha yokuhlola yesoftware yokuminyanisa okushisayo kanye nezibalo zezibalo ezinhlungwini ze-0.3, 0.5 kanye no-0.7. dweba. Ngokuhlaziywa kwe-coefficient yokuhlakazeka kwamandla (η) kanye ne-coefficient yokungazinzi (ξ (έ)) esithombeni, kunqunywa ukuthi izinga lokushisa kwe-deformation lingu-260 ~ 350℃, isilinganiso sobunzima ngu-0.01 ~ 1s -1, okuyi-machining eshisayo epulasitiki ye-die-cast AZ91D magnesium alloy. Indawo engcono kakhulu yokwenza imishini.
3. Ku-die-cast AZ91D magnesium alloy, kunezigaba zesibili eziningi ezisatshalaliswa emingceleni yezinhlamvu kunethiwekhi. Lezi zigaba zesibili zincibilika kancane ku-matrix ngokwanda kokushisa kokushiswa kokucinana okushisayo; ukubonwa kwesakhiwo esishisayo sokuminyanisa se-die-cast AZ91D magnesium alloy kukhombisa ukuthi izinga lokushisa kwe-deformation, izinga lokucindezela, kanye nobunzima kuthinta ukushisa kokuminyanisa isakhiwo Okubalulekile; umehluko wesakhiwo ezindaweni ezahlukahlukene zesampula efanayo usobala ngokwengeziwe, ukusonteka kukhulu endaweni esenkabeni eduze kwesampula, ukwakheka kwebhendi okuqondiswe kahle kuqondiswa kusiqondiso sokucindezelwa esikhiqizwa yisakhiwo kusobala kakhulu, futhi ukuphinda kusetshenziswe kabusha okunamandla kwenzeka okusanhlamvu umngcele. Kodwa-ke, inani lokuguquguquka kwezicubu lincane eduze komphetho we-deformation yesampula, futhi izicubu zikhula ngokulula.
4. Ukuqaphela i-morphology yezinto ezibonakalayo zokuphonsa ekufeni lapho kucindezelwa ukushisa okushisayo kukhombisa ukuthi ukukhubazeka okufana nembobo yikhona ukukhubazeka okuyinhloko kwama-alloys e-die-cast magnesium, futhi ukucindezelwa kwepulasitiki kuyindlela ephumelelayo yokunciphisa inani leziphambeko.

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe: Ukuziphatha Okucindezelayo Okushisayo Kwe-Die-Cast AZ91D Magnesium Alloy

UMinghe Inkampani yeDie Casting anikezelwe ekukhiqizeni nasekuhlinzekeni ikhwalithi nokusebenza okuphezulu Izingxenye Zokulingisa (izingxenye zensimbi zensimbi zokufa zisebenza ikakhulukazi zibandakanya I-Thin-Wall Die Casting,I-Hot Chamber Die Casting,Cold Chamber die Casting), Insizakalo Eyindilinga (Insiza Yokulingisa,ICnc Machining,Ukwenza Okubandayo, Surface Treatment) .Noma ikuphi ukusakazwa kwe-Aluminium die, i-magnesium noma i-Zamak / zinc die casting nezinye izidingo zokuphosa zamukelekile ukuxhumana nathi.

Ngaphansi kokulawulwa kwe-ISO9001 ne-TS 16949, Zonke izinqubo zenziwa ngamakhulu emishini esezingeni eliphakeme yokufa, imishini ye-5-axis, nezinye izikhungo, ezisukela kuma-blasters kuya kumishini yokuwasha ye-Ultra Sonic.Minghe akagcinanga ngemishini esezingeni eliphezulu kepha futhi unobuchwepheshe iqembu lonjiniyela abanolwazi, ama-opharetha nabahloli ukwenza ukwakheka kwekhasimende kugcwaliseke.

Umenzi wenkontileka yokufa kwabasikiwe. Amandla afaka izingxenye ezibandayo ze-aluminium die casting ezivela ku-0.15 lbs. kuye ku-6 lbs., Ukusetha ushintsho olusheshayo, nemishini. Izinsizakalo ezingezwe ngenani zifaka phakathi ukupholisha, ukudlidliza, ukuphazamisa, ukuqhumisa ngokudubula, ukupenda, ukuhlobisa, ukumboza, ukuhlangana nokusetshenziswa kwamathuluzi. Izinto zokusebenza ezisetshenzisiwe zifaka ama-alloys afana no-360, 380, 383, no-413.

I-Zinc die casting design usizo / izinsizakalo zobunjiniyela ezihambisanayo. Umenzi wangokwezifiso we-precision zinc die castings. Ukusakazwa okuncane, ukukhishwa kwengcindezi ephezulu, ukusikeka kwesikhunta esiningi, ukujikijelwa kwesikhunta okuvamile, ukufefa kwamayunithi kanye nokuzimela okuzimele kanye nokuvalwa okuvaliwe komgodi kungenziwa. Ama-Castings angenziwa ngobude nobubanzi obufinyelela ku-24 in. Ku +/- 0.0005 in. Ukubekezelelana.  

I-ISO 9001: Umkhiqizi oqinisekisiwe ka-2015 we-die cast magnesium, Amandla afaka i-high-pressure magnesium die casting up to 200 ton chamber hot & 3000 ton cold chamber, designing designing, polishing, molding, machining, powder & liquid paint, QA full with CMM amakhono , inhlangano, ukupakisha nokulethwa.

Kuqinisekiswe i-ITAF16949. Insiza Eyengeziwe Yokulingisa Faka ukukhipha utshalomali,ukuphonsa kwesihlabathi,Ukuphonswa kwamandla, Lost Foam Ekubunjweni,I-Centrifugal Casting,Ukuphoswa Kokuqothula,Permanent Isikhunta Ukulingisa, Amakhono afaka i-EDI, usizo lobunjiniyela, ukumodeliswa okuqinile nokucutshungulwa kwesibili.

Izimboni Zokulingisa Izingxenye Zamacala Ezifundo Zezimoto: Izimoto, Amabhayisikili, Izindiza, Izinsimbi Zomculo, I-Watercraft, Amadivayisi we-Optical, Izinzwa, Amamodeli, Amadivayisi we-elekthronikhi, Ukuvaleka, Amawashi, Imishini, Izinjini, Ifenisha, Ubucwebe, AmaJig, Telecom, Ukukhanyisa, Amadivayisi Wezokwelapha, amadivayisi wezithombe, Amarobhothi, okubaziwe, okokusebenza komsindo, okwezemidlalo, i-Tooling, Amathoyizi nokuningi. 

Yini esingakusiza ukuthi uyenze ngokulandelayo?
