Ukuphosa ukufasisetyenziswa rhoqoubuchule bokubumba inaliti yesinyithioko kubandakanya ukugalela izinto ezigalelwe kumngundo, ukufaka uxinzelelo lokubangela ukuba izinto zingasebenzi ngexesha elibandayo eliqhelekileyo kunye nokulungiswa okushushu, kwaye emva koko kususwe izinto ezilahlayo kubumba ukwenza ubume obufunwayo.
Ukuze ufezekise iimfuno zemveliso yobuninzi, ubuchule bokuphosa ukufa buluncedo ekunciphiseni ukusetyenziswa kwezinto eziphathekayo, kunokunciphisa umjikelo wokubumba, kunye nesiphumo sokubumba kunye nokusebenza kuzinzile.
Imveliso yokuphosa i-die ixhomekeke kuyilo lwe-die casting mold, enefuthe elithe ngqo kwinkqubo yokuphosa ukufa kunye nesiphumo sokubumba. Uyilo lokubumba lokubumba oluchanekileyo lunokubonelela ngemveliso yokusebenza kakuhle, ngelixa uyilo olungalunganga lunokubangela isiphithiphithi senkqubo kunye ne-scrap, ukuphakamisa iindleko zokuvelisa kunye nokuyila kwakhona. Ukuze kuqinisekiswe ukuba ukufa ukugalela umngundo uye ukuxhathisa ngokwaneleyo banxibe, ukuxhathisa iasidi kunye alkali, ukuxhathisa umhlwa, kwakunye nokutywina obalaseleyo, uzinzo thermal, kunye nezinye egqwesileyo ukusebenza ukugalela ukufa, uyilo kufa ukuphosa ngundo kufuneka kuthathelwe ingqalelo izinto ezisetyenzisiweyo, iindlela unyango ubushushu, isakhiwo ngundo, ubungakanani umngundo, parameters ngundo, ukucocwa komhlaba, kunye neminye imiba.
Uyilo lokubumba lokufaKufuneka basebenzise ukulinganisa okuguquguqukayo kwekhompyutha kunye nohlalutyo lwetekhnoloji yento ephelayo ukuze kunyuswe uyilo usebenzisa indlela entsha, ukuqonda uphuhliso olukhawulezayo lwemveliso, mfutshane umjikelo wophuhliso, kunye nokuphucula umgangatho wemveliso.
Nangona uyilo oluchanekileyo lubonelela ngesiseko esiluqilima sokuphosa iinxalenye ezintsonkothileyo, kukho iingozi ezibandakanyekayo ngokunjalo, ke ngoko ukuphunyezwa kokungunda kokuphosa kufuneka kuhlengahlengiswe ngokuqhubekayo ngokuhambelana nendawo yokwenyani yokusebenza.
Iimpawu kunye nobubanzi bezicelo zetekhnoloji yokuphosa
Iimpawu zeteknoloji ye-1.die casting
Iimpawu ezimbini eziphambili zenkqubo yokubumba i-liquid okanye i-semi-liquid yokuzalisa isinyithi esetyenziselwa ukufakela, kunye nezahlulo ezimbini eziphambili phakathi kweteknoloji yokufa kunye nezinye iindlela zokuphosa, zixinzelelo oluphezulu kunye nesantya esiphezulu.
2. Ukusetyenziswa kweteknoloji yokuphosa
Enye yezona ndlela zibalaseleyo zobuchule bokwenza isinyithi kukuphosa ukufa, kwaye kusebenza kakuhle ukuvelisa iinxalenye ezingenanto encinci.
Okwangoku, ii-alloys ezisetyenziselwa ukuphosa ngokufa ngokuthe ngcembe zanda ukuya kwizixhobo ezingaphandle kwe-zinc, i-aluminium, i-magnesium, kunye nealloys zobhedu.
Ii-Die castings zenziwe nge-iron alloys njengentsimbi kunye nentsimbi.
Die ukuphosa izinto zokubumba
Ngokohlobo lwesinyithi oluza kucutshungulwa, ubungakanani bomthwalo, ukusetyenziswa kobushushu kunye nesantya sokwenza, iimfuno ezahlukeneyo zibekwe phambili ukukhetha iintlobo ezahlukeneyo zomsebenzi oshushu wokufa. I-ω (c) ye-hot work die steel ngokuqhelekileyo i-0.3 ~ 0.6%, xa umxholo wekhabhoni uphezulu kakhulu, ukuqina kunye neplastiki yokuhla kwensimbi, kunye ne-thermal conductivity ihlwempu; Xa umxholo wekhabhoni uphantsi kakhulu, ubunzima kunye nokuxhatshazwa kokugqoka akukwazi ukuhlangabezana neemfuno.
Hot umsebenzi die intsimbi ngokubanzi ukongeza Cr, Mn, Ni, Si kunye nezinye izinto ukomeleza matrix ferritic, ukuphucula amandla ukuqina kunye nokuqina intsimbi, Ni nako ukuphucula ukumelana ukudinwa thermal, ukuze kusulungekiswe okuziinkozo ukuphucula amandla kunye nobulukhuni, ukuzinza tempering, ukuthintela ukucaphuka brittleness, kodwa kwakhona ukongeza Ni, Mo, V kunye nezinye izinto. Ukongeza, i-Ni, i-Mo, i-V kunye nezinye izinto zihlanjululwa ngendlela ye-carbide ngexesha lokufudumala ukuvelisa ukuqina kwesibini, ukuze umsebenzi oshushu ufe intsimbi unokukwazi ukugcina amandla aphezulu kwiqondo lokushisa eliphezulu.
Aluminiyam ngundo
Ngoxinano oluphantsi kunye namandla aphezulu, i-alloy ye-aluminiyam iya ithandwa ngakumbi. Emva kokuba ukwakhiwa kweekhemikhali kuphuculwe,ukuphosa i-aluminium, i-extrusion eshushu, kunye neenkqubo zokuguga ezenziweyo zisetyenziselwa ukuphucula ukusebenza kwayo. Iimveliso ezenziwe nge-aluminium alloy die-casting zisetyenziswa ikakhulu kumbane, iimoto, izixhobo zasekhaya, iimoto, kunye namashishini athile onxibelelwano. Iinqwelomoya ezinkulu, iinqanawa, kunye namanye amashishini aneemfuno zobugcisa eziphakamileyo nawo asebenzisa iimpahla ze-aluminiyam ezikumgangatho ophezulu ezinomgangatho ophezulu wokusebenza, ukuchaneka okuphezulu, kunye nokuqina okuphezulu, nangona ukusetyenziswa kwazo okuphambili kusekho kwiindawo ezithile zoomatshini.
Ubuchwephesha bokuphosa be-aluminiyam bugqwesile kubugcisa obuqhelekileyo bokwenza i-aluminiyam i-alloy ngeendlela ezilandelayo: iindidi ezinkulu zokuphosa; Ngokuthe ngcembe uzinzo olulungileyo kunye nokuchaneka komgangatho ophezulu; Amandla okuphosa, ubunzima obuphezulu bomphezulu, uburhabaxa obusezantsi, imveliso ephezulu, izinga eliphezulu lokusetyenziswa kwesinyithi, njalo njalo.
Indlela yophuhliso yoyilo lwesixhobo sokuphosa ukufa
Uyilo lokungunda kufuneka luthathele ingqalelo iimfuno ezicinezelayo zomsebenzisi zokuhanjiswa ngokukhawuleza, ukuchaneka okuphezulu, kunye nokuveliswa kokungunda okufikelelekayo.
Ezi ndlela zokukhula zilandelayo aziyi kuthinteleka:
1.Uyilo lokubumba ukusuka kwinqanaba lokucinga ukuya kwicala lohlalutyo lwethiyori kunye noyilo oluncediswa yikhompyuter.
Ishishini lokungunda lisebenzisa kakhulu itekhnoloji yeCAD/CAM/CAE, ekhulisa kakhulu umthwalo wokungunda kwaye yenza ulwakhiwo lomngundo lube nengqiqo nenzululwazi.
I-2.Precision, uyilo olukhawulezayo lokubumba kunye nenkqubo yokuvelisa, kunye nomjikelezo omfutshane wokuphuhlisa imveliso.
