Baza, ngezibumbi esantini-udongwe: eziluncedo

Iinkqubo yemveliso Foundry ze okusilelayo metal zicwangciswe ngeendlela ezahlukeneyo. Njengoko imveliso leyo ixhomekeke kakhulu ngokwesiseko iimpawu ngokusekelwe into eyenziwe, oko kukuthi, imilo, umkhosi lizele ikamva izinto workpiece. Enye iiteknoloji kakhulu ethandwayo ukulahlwa ngezibumbi esantini-udongwe, enika ezininzi iingenelo. Indlela kakhulu ubudala, kodwa ngenkuthalo ezisetyenziswayo xa kwenziwa imveliso ngamanqanaba ahlukeneyo - ukusuka zocweyo amancinci kumashishini amakhulu.

ulwazi ngokubanzi malunga nobuchwepheshe

inqubo yokubumba yinkqubo yobugcisa, nto leyo ikhokelele ukusuka etyhidiweyo billet esele eyakhiwe okanye imveliso ogqityiweyo kunye zejometri iparameters eziyimfuneko. Ukuze kuphunyezwe imilo olufunayo ehambelana neemfuno modeli esetyenzisiweyo. Yenethiwekhi isiseko ukulahlwa kule meko jeli intlabathi-udongwe. Kuye kwasekwa ngamaqela amabini amacandelo. Kwinxalenye yokuqala zirconia nesanti dust, kwaye eyesibini - kaolin nodongwe bentonite. Ngaloo ndlela bakha yindibanisela umboniso omnye, nto leyo ngexesha umsebenzi ufumana elizayo izinto workpiece. Kodwa oku zonke iinxalenye ngokusekelwe leyo waqaphela ephosa ifomu entlabathini. Ithekhnoloji ayikho ngaphandle ikhithi imodeli, nto leyo uhlobo imodeli ukuvunwa elizayo. Ngokuba lo Ukulinganisa kusetyenziswa izilwanyana okanye ukululekwa kwi machining zemathiriyeli - ezifana ngomthi okanye metal ukukhanya. Noko ke, isiseko spineless kusebenza kuphela kwiimeko apho kuyimfuneko ukwenza into ekujoliswe kulo. Kodwa kwenzeka ukuba inkosi deal with iimveliso esele zenziwe, ezo parameters kufuneka uphindaphindwe ngokwenza. Ngoku kuyimfuneko ukuya ngqo iinzuzo obu bugcisa.

A iintlobo

Ukuntsonkotha ngokusebenzisa iintlobo ezininzi kunye neemodeli ekubunjweni kukuba ubuchwepheshe ayiboneleli ukuba intshabalalo yesakhiwo. Oku kakhulu amagunya ubuchule ngokusebenza, umsebenzi kunye nabasebenzi nzima. Kwimeko iifom kwesanti-udongwe azikho kwempembelelo, kuba ekuqaleni indlela ithatha ukusetyenziswa ngumngundo elinye. Noko ke, oku akuthethi ukuba izixhobo ngebhegi ukho umgaqo ngaphandle. Ngenxa yezizathu kwifomu koqoqosho inokusetyenziswa urhwebo, ukuba oko akuhambi neemfuno eziphumo zokuphela konyaka le nkqubo. eziluncedo zobungcali lombutho sokufaka ngezibumbi esantini-udongwe zibethwa emiselwe Indlela ngakwicala lokwenziwa komsebenzi. Kwimeko omnye-sifuba snap-in enokulindelwa ekususeni ukungunda ngaphandle kokonakalisa ngayo, siphoswe kunye parameters ezifunekayo. Olu khetho isoloko isetyenziswa castings ezilula. Kodwa xa kufikwa kuyilo workpieces ezimbaxa, sebenzisa uhlulo eziwayo ifomu, apho nje akukho sithintelo ngokwemigaqo parameters imveliso efunekayo.

ukufumaneka kwezobugcisa inkqubo umbutho

Umzekelo iimowuldi isanti ekubunjweni ubonisa indlela kusilungele, ukuba ubuchule yemveli imveliso phezu ngoku. Kule meko kubangelwa ekubunjweni elula lombutho. Olu tyando kufuneka kuphela isethi izinto-ikhankanywe ngasentla ukuze kususwe tooling kunye ngumzekelo, nto leyo nayo akafuni ukuba iinkqubo ezintsonkothileyo. indlela esezantsi for yokubumba ukuze zenziwe ngomthi njengesixhobo i womchweli ngogesi yakhe. Ngaphandle kokuba elijongene kumashishini ekuvelisweni castings ngokwemilo entsonkothileyo isetyenziswa kwaye processing ezongezelelweyo kunye ukumithisa le nto. Kwakhona, ukuntsonkotha nesanti ngodongwe ezahlukeneyo kunye nefomu wenza udaka ngentsimbi kunye zeplastiki. Kodwa ke, kwakhona, kufikwa imveliso ezikhethekileyo. Practice ubonisa ukuba malunga 80-90% yazo zonke castings yenziwe ehlabathini esebenzisa izakhiwo ezilula ngokohlobo lwezixhobo ezindala kunye namagumbi omisa eqhelekileyo.

kwezoqoqosho

Ngokuqhelekileyo, ukusetyenziswa kuquka umboniso abangatshatanga kunye nenkqubo eninzi. Ngoko ke, ukuba ukujongana izigqibo ezinjalo kuphela kwiimeko ezigabadeleyo, ukuba ufuna ukuvelisa iinxalenye okanye iifom design isiko. Kodwa lo mkhuba umva libonisa Foundry. Ulingano esantini-udongwe ngumngundo kufanelekile imali, nakumatyala ezisetyenziswa siyitshabalalise iziseko. Oku kunganxulunyaniswa malini-ngempumelelo kwaye kwifom ngokwayo, kwaye kubume umzekelo.

Ngazibini ubuchwepheshe

Kukho iinkalo ezimbalwa zemveliso, nenokuthi umda imihlaba isicelo obu bugcisa. Oku esetyenziswa kwishishini, ulwakhiwo, ukwakheka amancinci-inyanda kwaye isiqwenga iindawo efanelekileyo, kwiindibano ezithile, njalo-njalo. D. Ngaphandle kokuba imigca engemveliso ekumgangatho ophakamileyo-ngqo ekhethekileyo musa ukuvumela le nkqubo kuba awukwazi ukunika inqanaba elifanelekileyo okuchaneka lweempawu workpiece. Kodwa kwakhona ukusuka kwindawo imbono malunga nendlela olusebenza ngayo ebuntsimbi linyibilike nsimbi esidumileyo ime kwezinye ubugcisa ephosa ifomu entlabathini. Ngokufutshane abonisa engafanelekanga ukusebenzisa iqela zesinyithi eliyinjubaqa kunokuba iintlobo exutyiweyo. metal Traditional exonxiweyo efanelekileyo ngokugqibeleleyo ukuze zisetyenziswe umsebenzi yokubumba le.

ukukhubazeka ukulahlwa kunokwenzeka

Ingongoma ezibuthathaka obu bugcisa, njengoko kuchaziwe apha ngasentla, na ukuchaneka eliphantsi yoMgaqo-workpiece. Products afunyenwe rough, akusoloko macala, kwaye ubukho iziphene ezithile. Le ifuthe le, kwelinye icala elingemva uburhabaxa kunye lula tooling kwimveliso. Ngaphandle, bephosa ekwimo intlabathi ivumela imingcipheko abangena ekubunjweni ukwakhiwa inclusions nonmetallic. Kuxhomekeka intsimbi ngokwayo unokuthabatha indawo kunye porosity negesi. Kodwa ke oku akuthethi ukuba iziphene zibe eziyimiqobo emibi ukusetyenziswa kwezi zobugcisa nesanti sukube. Ukuze ukuvala esi sithintelo kuba ukuthotyelwa kwemithetho ekubunjweni esemgangathweni.

Izindululo for quality preform

Technology Amacebiso follow ezimbini ezisisiseko nemithetho eza kufutshane kokuhlela elindelweyo japan. Okokuqala, kufuneka ukunqanda ukusetyenziswa indlela kwindawo fluidity sezantsi kwesikhundla sentsimbi. Into yokuba izinga okupholisa eliphezulu uyakwazi ukukhuthaza Ukupholisa olunzulu baphele, ebangela ukuyilwa ezidibanayo kunye underfilling. Le ezincinane yesibini, ngaphandle apho ayenzi ulahle yobungcali uman ngezibumbi kwesanti-udongwe iinkxalabo kwizicatshulwa ukungazinyamezeli encinane ngokwemiqathango workpiece. Ukwanda Izicwangciso ekuqaleni ukuvumela zoomatshini ukulungisa imveliso ngaphandle umngcipheko ngesiphelo.

isiphelo

Ithekhnoloji ilula nefikelelekayo, kodwa oku akuthethi ukuba akukho nto ebandakanya uphuhliso. Kwezinye iindawo ezikhupha ngezibumbi esantini-zodongwe ngcono, yokwandisa inkqubo kunye nokuphelisa ezinye amaphutha ayo. Isebe kakhulu ababekekileyo nathembisayo indlela kucingwa ukuba bakhutshwe fomu. Imithetho-siseko usebenzisa intlabathi kuhlala injalo, Noko ke, njengoko Umatshini ngodongwe isiseko component qela kule meko ngaphandle.
