Txheej txheem cej luam: Dab tsi yogaluminium tuag casting?
Lub hauv paus ntawm aluminium tuag casting
Aluminium tuag casting yog txheej txheem tsim los ua kom raug dimensioned, sharply txhais, smooth los yog textured-nto txhuas qhov chaw los ntawm kev siv cov reusable pwm, hu ua tuag.Cov txheej txheem txhuas tuag casting yog siv rau hauv qhov cub, aluminium alloy, tuag casting tshuab, thiab tuag.Tuag uas feem ntau tsim nrog ntev-ntev, zoo steel muaj tsawg kawg yog ob ntu kom tso cai tshem tawm cov castings.
Aluminium tuag casting ua haujlwm li cas?
Aluminium casting tuag uas tsim los siv cov cuab yeej hardened steel yuav tsum tau ua nyob rau hauv tsawg kawg yog ob seem kom castings yuav raug tshem tawm.Cov txheej txheem txhuas tuag casting muaj peev xwm ua tau ntau txhiab tus txhuas castings hauv kev ua tiav sai.Cov tuag yog ruaj khov rau hauv lub tshuab tuag casting.Lub ib nrab tuag yog nyob ruaj ruaj.Ib qho ntxiv, qhov txhaj tshuaj tuag ib nrab, yog txav tau.Aluminium casting tuag tuaj yeem ua tau yooj yim lossis nyuaj, nrog rau cov swb, cores lossis lwm qhov chaw, nyob ntawm qhov nyuaj ntawm qhov casting.Txhawm rau pib txheej txheem tuag casting, ob qhov tuag halves yog clamped ua ke los ntawm lub tshuab casting.Kub kub ua kua aluminium alloy yog txhaj rau hauv cov kab noj hniav tuag thiab sai sai solidified.Tom qab ntawd lub movable tuag ib nrab yog qhib thiab aluminium casting yog ejected.
Kev lag luam

Kev lag luam uas siv aluminium tuag casting
Aluminium tuag casting qhov chaw yog dav siv hauv tsheb, tsev neeg, hluav taws xob, hluav taws xob, kev tsim kho thiab kev lag luam.
Pwm los yog cuab yeej

Ob tug tuag yog siv nyob rau hauv tuag casting;ib qho yog hu ua "cover die half" thiab lwm qhov "ejector tuag ib nrab".Qhov twg lawv ntsib yog hu ua txoj kab sib faib.Lub hau npog tuag muaj cov sprue (rau cov tshuab kub chamber) los yog lub qhov (rau cov tshuab txias chamber), uas tso cai rau cov hlau molten ntws mus rau hauv cov tuag;qhov no feature sib xws nrog lub injector nozzle ntawm lub tshuab kub chamber los yog tua chamber nyob rau hauv txias-chamber tshuab.Lub ejector tuag muaj cov ejector pins thiab feem ntau yog tus khiav, uas yog txoj hauv kev los ntawm sprue los yog qhov txhaj tshuaj mus rau lub pwm kab noj hniav.Lub npog tuag yog ruaj khov rau qhov chaw ruaj khov, lossis pem hauv ntej, platen ntawm lub tshuab casting, thaum lub ejector tuag yog txuas rau lub movable platen.Cov kab noj hniav pwm yog txiav rau hauv ob kab noj hniav, uas yog cov khoom sib cais uas tuaj yeem hloov tau yooj yim thiab ntsia liaj qhov rooj rau hauv qhov tuag halves.
Cov tuag yog tsim los kom cov tiav casting yuav swb tawm ntawm lub hau ib nrab ntawm cov tuag thiab nyob rau hauv lub ejector ib nrab raws li cov tuag yog qhib.Qhov no paub tseeb tias qhov casting yuav raug tshem tawm txhua lub voj voog vim tias lub ejector ib nrab muaj cov ejector pins los thawb lub casting tawm ntawm qhov tuag ib nrab.Lub ejector pins yog tsav los ntawm lub ejector tus pin phaj, uas yog tsav tag nrho cov pins nyob rau tib lub sij hawm thiab nrog tib lub zog, thiaj li hais tias lub casting tsis puas.Lub ejector tus pin phaj tseem retracts tus pins tom qab ejecting lub casting los npaj rau kev txhaj tshuaj tom ntej.Yuav tsum muaj cov pins ejector txaus kom lub zog tag nrho ntawm txhua tus pin qis, vim tias qhov casting tseem kub thiab tuaj yeem raug puas los ntawm kev quab yuam ntau dhau.Cov pins tseem tshuav ib qho cim, yog li lawv yuav tsum nyob rau hauv qhov chaw uas cov cim no yuav tsis cuam tshuam rau lub hom phiaj casting.
Lwm cov khoom siv tuag muaj xws li cores thiab slides.Cores yog cov khoom uas feem ntau tsim qhov los yog qhib, tab sis lawv tuaj yeem siv los tsim lwm cov ntsiab lus thiab.Muaj peb hom cores: tsau, txav tau, thiab xoob.Cov cores ruaj khov yog cov uas tau taw qhia thaum uas tig mus rau qhov kev taw qhia rub ntawm cov tuag (xws li cov kev taw qhia qhov tuag qhib), yog li lawv tau tsau, lossis txuas mus tas li rau qhov tuag.Movable cores yog cov uas tau taw qhia rau lwm txoj hauv kev tshaj li qhov sib npaug mus rau kev coj mus rub.Cov cores no yuav tsum tau muab tshem tawm ntawm qhov tuag kab noj hniav tom qab txhaj tshuaj solidifies, tab sis ua ntej qhov tuag qhib, siv ib qho kev sib cais.Slides zoo ib yam li cov cores txav tau, tshwj tsis yog lawv tau siv los ua qhov chaw undercut.Kev siv cov cores txav tau thiab swb tau zoo heev ua rau tus nqi tuag.Loose cores, tseem hu ua pick-outs, yog siv los nrum intricate nta, xws li threaded qhov.Cov cores xoob no tau muab tso rau hauv qhov tuag ntawm tes ua ntej txhua lub voj voog thiab tom qab ntawd ejected nrog rau qhov kawg ntawm lub voj voog.Lub hauv paus ces yuav tsum tau muab tshem tawm ntawm tes.Cov cores xoob yog hom kim tshaj plaws ntawm cov tub ntxhais, vim tias muaj kev ua haujlwm ntxiv thiab lub sijhawm ua haujlwm ntau ntxiv.Lwm qhov tshwj xeeb hauv cov tuag muaj xws li cov dej txias thiab cov vents raws cov kab sib faib.Cov vents no feem ntau yog dav thiab nyias (kwv yees li 0.13 hli lossis 0.005 hauv) yog li ntawd thaum cov hlau molten pib sau lawv cov hlau sai sai thiab txo cov khoom seem.Tsis siv cov risers vim tias qhov kub siab ua kom muaj kev noj cov hlau tsis tu ncua ntawm lub rooj vag.
Cov khoom tseem ceeb tshaj plaws rau cov tuag yog thermal shock tsis kam thiab softening ntawm qhov kub thiab txias;Lwm yam khoom tseem ceeb muaj xws li hardenability, machinability, kub checking kuj, weldability, muaj (tshwj xeeb tshaj yog rau loj tuag), thiab nqi.Lub neej ntev ntawm kev tuag yog ncaj qha nyob ntawm qhov kub thiab txias ntawm cov hlau molten thiab lub sij hawm voj voog.[16]Cov tuag uas siv hauv kev tuag casting feem ntau yog ua los ntawm cov cuab yeej hardened, vim cam khwb cia hlau tsis tuaj yeem tiv taus cov kev kub ntxhov siab, yog li cov tuag yog kim heev, ua rau cov nqi pib siab.Cov hlau uas raug pov rau ntawm qhov kub siab dua yuav tsum tau tuag ua los ntawm cov hlau alloy siab dua.
Lub ntsiab tsis ua hauj lwm hom rau tuag casting tuag yog hnav los yog yaig.Lwm hom kev ua tsis tiav yog kev kuaj xyuas cua sov thiab thermal qaug zog.Kev kuaj xyuas cua sov yog thaum cov kab nrib pleb tshwm sim ntawm qhov tuag vim qhov hloov pauv loj ntawm txhua lub voj voog.Thermal qaug zog yog thaum cov kab nrib pleb tshwm sim ntawm qhov tuag vim muaj ntau lub voj voog.
