Xuab zeb casting, ua cov txheej txheem hlau tso cai, yog siv dav hauv kev tsim khoom machinery, automotive, entospace, thiab lwm yam kev siv tau dav, cov nqi qis, thiab cov txheej txheem yooj yim. Tus txheej txheem no cuam tshuam nrog cov hlau pov tseg rau hauv cov xuab zeb pwm, txias thiab ua rau pom kev ua duab uas xav tau. Cov hauv qab no piav qhia cov txheej txheem ntau lawm thiab cov ntsiab lus tseem ceeb ntawm cov xuab zeb casting.
1. Txheej Txheem Npaj Ua Haujlwm
Thawj kauj ruam hauv xuab zeb casting yog txheej txheem tsim thiab kev npaj khoom ua raw. Ua ntej, phiaj xwm parting yuav tsum raug txiav txim siab raws li qhov chaw kos duab, kom pom tseeb xws li qhov kev sib tw thiab risE, Wrinkage Allowance, thiab khoom siv. Tom ntej, tsim nyog cov ntaub ntawv molding yog xaiv, suav nrog cov xuab zeb (xws li Silica Xuab Zeb), xws li cov hmoov av sillica (xws li cov hmoov av (xws li anti- sticking txheej). Lub particle loj thiab purity ntawm cov ntaub ntawv nyoos ncaj qha cuam tshuam rau saum npoo ntsug ntawm lub cam khwb cia, thaum hom kev txiav txim siab lub zog thiab kev sib txuas ntawm cov xuab zeb pwm.
Ii. Pwm Cov Txheej Txheem
1. Qauv thiab tub ntxhais xa khoom
Tus qauv yog qhov zoo tsis zoo ntawm lub camting, feem ntau ua los ntawm ntoo, hlau, lossis yas, thiab yuav tsum muaj tseeb txog qhov cam khwb cia geometric nta. Rau cov txheej txheem nyuaj, ntxiv cov xo tsuab ntxiv yog yuav tsum tau tsim cov kab noj hniav sab hauv, uas yog tom qab ntawd ces nias rau hauv cov duab los ntawm lub thawv tseem ceeb. Hauv cov txheej txheem niaj hnub, 3D luam ntawv tshuab tau nce siv rau cov qauv sai ntau lawm, ua kom luv heev cycles.
2. Moulding xuab zeb npaj thiab cov kab ke
Moulding xuab zeb yog sib xyaw ntawm cov xuab zeb nyoos, binder, thiab dej nyob rau hauv ib qho kev sib sau ua feem. Lub xuab zeb surmin sib tov sib xyaw kom txog thaum nws mus txog qhov xav tau cov yees duab. Thaum lub sij hawm moulding txheej txheem, cov xuab zeb tau cog rau hauv qhov muag ntawm tus kheej lossis mechanically (xws li cov khoom siv vibectly los yog tseem ceeb shooter los tiv thaiv qhov cuam tshuam ntawm cov hlau molten. Parting cov kev npaj saum npoo av kom cov pob zeb ua kom haum pwm thiab zam kev ua tsis yog neeg misalignment.
III. Melting thiab hliv cov txheej txheem
1. Cov hlau melting
Ua raws li cov khoom siv casting yuav tsum tau, cov hlau nrum hlau, lossis tsis yog {{0} {} cov roj txhuas) tau raug xaiv los ua cov khoom siv raw. Cov cuab yeej melting suav nrog Cupolas, hluav taws xob arc rauv, lossis induction rauv. Qhov ntsuas kub (piv txwv li, kwv yees li cas, kwv yees li ntawm 1350-1450℃yuav tsum tau tswj cov kab mob grey Kev ua kom ua haujlwm xws li deoxidation thiab kev tshem tawm slag yog qhov tseem ceeb rau kev txhim kho cov khoom zoo.
2. Kev siv ntawm lub pouring system
Ua ntej pouring, lub khob ncuav, spru, khiav, thiab ingree yuav tsum tau sib sau ua ke los ua cov channel rau kev qhia cov hlau molten hlau. Lub ncuav txias thiab nrawm yuav tsum tau hloov kho raws li lub phab ntsa tuab ntawm lub ntsej muag tuab thiab}}}}} kub yuav tsum muaj kev tswj kom txias kom tsis txhob shrinkage kab noj hniav. Caw kaw lus pouring khoom siv (xws li Tilting Ladles) tuaj yeem txhim kho cov txheej txheem kev ruaj khov.
IV. Cua txias thiab tu theem
1. Cib ua ke thiab tsis tuajpacking
Lub molten hlau txias thiab solidifies hauv cov xuab zeb pwm. Lub sijhawm xav tau nyob ntawm qhov loj me ntawm cov casting (feem ntau ob peb feeb txog ob peb teev). Unpack cov pwm me me thaum ntxov yuav ua rau muaj kev tawg lossis kub tawg. Qhov zoo tshaj sijhawm rau kev tsis tuaj yeem txiav txim siab yuav tsum txiav txim siab raws kev paub lossis simulation software.
2. Post {{{{}} ua thiab tshuaj xyuas
Tom qab kev ua kom pom tseeb, qhov kev ua kom dim yuav tsum raug tso tawm los ntawm Sprue, Flash, thiab cov xuab zeb tseem ceeb. Cov hau kev sib tsoo muaj cov roj txiav, sib tsoo, lossis kev ntsug sand tshem tawm. Kev tawm sab hauv yog tom qab tau soj ntsuam los ntawm x- kev soj ntsuam hluav taws xob, kev kuaj hluav taws xob, lossis cov teeb meem saum npoo av tau raug kho los ntawm sandblasting lossis polishing. Lub Casting kawg yuav tsum tau ua tiav qhov ntev thiab cov khoom ua neeg kho kom zoo nkauj.

Tus qauv yog qhov zoo tsis zoo ntawm lub camting, feem ntau ua los ntawm ntoo, hlau, lossis yas, thiab yuav tsum muaj tseeb txog qhov ua kom pom lub ntsej muag. Rau cov txheej txheem nyuaj, cov xuab zeb tseem ceeb yog tsim cov khoom tsim los ua cov kab noj hniav hauv. Cov tub ntxhais xuab zeb yog tom qab ntawd nias rau hauv cov duab uas siv lub thawv tseem ceeb. Hauv cov txheej txheem niaj hnub, 3D luam ntawv tshuab tau nce siv rau cov qauv sai ntau lawm, ua kom luv heev cycles.
2. Moulding xuab zeb npaj thiab cov kab ke
Moulding xuab zeb yog sib xyaw ntawm cov xuab zeb nyoos, phau ntawv, thiab cov dej nyob hauv cov proportions tsim nyog. Nws yog tus tseem mob siab nyob rau hauv lub xuab zeb tov khoom kom ua tiav qhov xav tau cov yees duab. Thaum lub sij hawm moulding txheej txheem, cov xuab zeb tau cog rau hauv cov cua ntawm manually lossis mechanically (xws li cov khoom siv vibe los yog ua kom muaj kev cuam tshuam txaus los tiv thaiv kev cuam tshuam ntawm cov hlau molten. Parting nto kev kho kom ntseeg tau cov pwm raug thiab zam kev tsis zoo.
III. Melting thiab hliv cov txheej txheem
1. Cov hlau melting
Ua raws li cov khoom siv casting yuav tsum tau, cov hlau nrum hlau, lossis tsis yog {{0} {} aluminium alloys) tau raug xaiv los ua cov ntaub ntawv raw. Cov cuab yeej melting suav nrog Cupolas, hluav taws xob arc rauv, lossis induction rauv. Qhov ntsuas kub (piv txwv li, kwv yees li 1350-1450℃rau cov xim grey cam khwb cia hlau) thiab cov khoom siv tshuaj uas yuav tsum tau tswj hwm thaum lub sijhawm. Lub tshuab hluav taws xob yog siv los saib xyuas cov lej alloy hauv lub sijhawm tiag tiag. Kev ua kom ua haujlwm xws li deoxidation thiab kev tshem tawm slag yog qhov tseem ceeb rau kev txhim kho cov khoom zoo.
2. Kev siv ntawm cov kev sib txuas lus
Ua ntej pouring, lub khob ncuav, spru, khiav, thiab ingree yuav tsum tau sib sau ua ke los ua cov channel rau kev qhia cov hlau molten hlau. Lub ncuav twj ywm kub thiab nrawm yuav tsum tau hloov kho raws li lub phab ntsa tuab ntawm lub cuab yeej siv hluav taws xob yuav tsum muaj kev mob khaub thuas kom tiv thaiv kom tsis txhob muaj shrinkage. Caw kaw lus pouring khoom siv (xws li tilting pw) tuaj yeem txhim kho cov txheej txheem kev ruaj khov.
IV. Cua txias thiab tu theem
1. Cib ua ke thiab tsis tuajpacking
Lub molten hlau txias thiab solidifies hauv cov xuab zeb pwm. Lub sijhawm xav tau nyob ntawm qhov loj me ntawm cov casting (feem ntau ob peb feeb txog ob peb teev). Unpack cov pwm me me thaum ntxov yuav ua rau muaj kev tawg lossis thermal tawg. Cov sijhawm zoo tshaj plaws rau cov pwm pwm yuav tsum txiav txim siab raws kev paub lossis simulation software.
2. Post {{{{}} ua thiab tshuaj xyuas
Tom qab kev rhuav tshem, tus kab yees duab yuav tsum tau muab tshem tawm ntawm cov pwm los ntawm kev tshem cov sprue, Flash, thiab cov xuab zeb tseem ceeb. Cov hau kev sib tsoo muaj cov roj txiav, sib tsoo, lossis kev ntsug sand tshem tawm.
