EkhayaI-Aluminiyam iDie-Casting
Iimveliso ze-aluminium die-cast zibhekisa kwiindawo eziveliswe ngenkqubo yokuphosa i-aluminiyam. Inkqubo ibandakanya ukufaka i-alloy aluminium etyhidiweyo kwi-mold yensimbi phantsi koxinzelelo oluphezulu. Nje ukuba isinyithi esinyibilikisiweyo siqine, ukungunda kuyavulwa kwaye indawo eqinileyo (ekwabizwa ngokuba yicasting) iyakhutshwa.
Ziyaziwa ngokuchaneka kwazo okubalaseleyo, ukugqiba umphezulu ogudileyo, kunye nokusebenza kakuhle kwemveliso. Ngenxa yeepropati zabo ezizodwa kunye neenzuzo, zisetyenziswa ngokubanzi kumashishini ahlukeneyo.
Inkqubo yokuphosa i-aluminiyam ibandakanya amanyathelo amaninzi. Okokuqala, i-alloy aluminium iyancibilika kwisithando somlilo kwaye ukungcola kuyasuswa ukuze kufezekiswe inqanaba elifunekayo lokucoceka. Isinyithi esinyibilikisiweyo sitofwa kumgodi wokungunda phantsi koxinzelelo oluphezulu kusetyenziswa umatshini wokuphosa uxinzelelo. Olu xinzelelo luphezulu lunceda ukugcwalisa imibumbo ngokukhawuleza kwaye yenze ukuba uyilo oluneenkcukacha kunye noluntsokothileyo. Emva kokuba isinyithi siqinile, ukubumba kuyapholiswa kwaye ukuphosa kuyakhutshwa. Ukufakwa kwe-castings kusenokuqhubekeka nokusetyenzwa ngakumbi njengokucheba, ukwenziwa komatshini, unyango olungaphezulu kunye nokuhlolwa komgangatho.
Iiprofayili zeAluminiyam zisetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yokuguquguquka kwazo, ukuqina, kunye neempawu ezikhaphukhaphu. Zinokufumaneka kulwakhiwo, kwezothutho, kwizinto zombane, nakwezinye izinto ezininzi. Ngelixa i-aluminiyam inokumelana nomhlwa kunye nomphezulu ogudileyo, unyango lomphezulu luhlala lusetyenziswa ukomeleza inkangeleko kunye neempawu zayo. Olunye unyango oluqhelekileyo lomphezulu lweeprofayili ze-aluminium lubandakanya:
Khaphukhaphu: I-Aluminiyam yaziwa ngeempawu zayo ezikhaphukhaphu, iyenza ilungele ukusetyenziswa apho ukunciphisa ubunzima kubaluleke kakhulu, njengemizi-mveliso yeemoto kunye ne-aerospace. Ubume obukhaphukhaphu beemveliso ze-aluminium die-cast kunceda ukuphucula ukusebenza kakuhle kwamafutha kunye nokunciphisa iindleko zizonke.
Amandla aphezulu: Ngaphandle kobunzima bazo, iimveliso ze-aluminium die-cast zinika amandla abalaseleyo kunye nentembeko yesakhiwo. Le propati ibenza bafanelekele izicelo apho amandla kunye nokuqina kubaluleke kakhulu.
Iimilo ezintsonkothileyo: Inkqubo yokuphosa i-die-casting inokuvelisa iimilo eziyinkimbinkimbi kunye nokuchaneka okuphezulu. Olu bhetyebhetye luvumela ukwenziwa kwamalungu antsonkothileyo angenakufikeleleka ngokulula ngezinye iindlela zokuvelisa.
Unyango loMphezulu oluNinzi: Iimveliso ze-Aluminiyam zokufa zingenziwa lula ukufikelela kwiintlobo ezahlukeneyo zonyango. Olu nyango lomphezulu lunokubandakanya ukupolisha, ukupeyinta, i-anodizing okanye i-powder coating ukunyusa i-aesthetics kunye nokumelana nokubola kwenxalenye. Iindleko ezisebenzayo: I-Aluminium die casting yinkqubo yokuvelisa esebenzayo kunye neendleko. Imveliso ephezulu, ukuchithwa kwezinto ezincitshisiweyo kunye neenkqubo zokuhlanganisana ezilula zifaka isandla ekusebenzeni kwayo kweendleko.
Kukho iintlobo ngeentlobo ze-alloys ze-aluminiyam ezisetyenziswa kwinkqubo yokufa, nganye ineempawu zayo ezizodwa kunye neepropati.
Ezinye ezisetyenziswa ngokuqhelekileyo i-die-cast aluminium alloys ziquka:
A380: yeyona aluminiyam isetyenziswa ngokuxhaphakileyo kwi-die casting. Ine-castability egqwesileyo, iipropati ezilungileyo zomatshini kunye ne-thermal ephezulu kunye ne-conductivity yombane. I-A380 isetyenziswa kakhulu kwimizi-mveliso yeemoto, zombane kunye nempahla yabathengi.
ADC12: Le ngxubevange ine-fluidity elungileyo kunye ne-castability kwaye ifanelekile ukuvelisa iimilo ezinzima. Inezicelo kwimizi-mveliso yeemoto kunye nombane.
A413: I-alloy ye-A413 yaziwa ngokugqwesa kwayo ukumelana nokugqwala kwaye isoloko isetyenziswa kwizicelo apho i-corrosion ixhalabile, njengamacandelo olwandle kunye nezixhobo zangaphandle.
A360: Le ngxubevange inokumelana noxinzelelo olugqwesileyo kunye nokumelana nomhlwa. Isetyenziswa kwizicelo ezifana neebhloko zenjini, uthumelo kunye namalungu oxinzelelo. Ukusetyenziswa kweemveliso ze-aluminium die-cast zibanzi kwaye ziyahluka. Zisetyenziswa ngokubanzi kwimveliso yeemoto ukuvelisa amacandelo e-injini, amacandelo othumelo kunye namacandelo esakhiwo. Kwishishini lombane, i-aluminium die castings isetyenziselwa ukuveliswa kweendawo ezivaliweyo zombane, izihlanganisi kunye nezindlu ze-radiator. Eminye imimandla yezicelo ibandakanya i-aerospace, iimveliso zabathengi, ukhuselo, uthungelwano ngocingo kunye namashishini oomatshini. Isishwankathelo, iimveliso ze-aluminium die-cast zizinto okanye iinxalenye ezenziwe ngenkqubo yokufa kusetyenziswa i-alloys ezahlukeneyo ze-aluminium. Inkqubo ibonelela ngezinto ezininzi eziluncedo, ezinje ngobunzima, amandla aphezulu, iimilo ezintsonkothileyo, ukugqiba okunokwenzeka, kunye nokusebenza kakuhle kweendleko. Kukho iintlobo ezininzi ze-aluminium alloys, kunye neemveliso ze-aluminiyam ze-die-cast zisetyenziswa kumashishini amaninzi.
