Lub hom phiaj tseem ceeb ntawm qhov ntws channel hauv pwm yog dab tsi?

1, Cov ntsiab lus tseem ceeb thiab kev faib tawm ntawm cov dej ntws
Raws li lub npe qhia, tus khiav yog ib txoj hauv kev los ntawm cov hlau molten ntws los ntawm cov sprue mus rau hauv pwm kab noj hniav thaum lub sij hawm casting txheej txheem. Raws li kev sib txawv casting, cov neeg khiav dej num tuaj yeem muab faib ua ntau hom, xws li sprues, runners, thiab runners hauv gravity casting, thiab gating systems hauv siab casting. Tus tsim ntawm cov channel no yuav tsum tau muab xam thiab layout raws li tej yam xws li casting puab, loj, khoom, thiab casting txheej txheem yuav tsum tau.
2, Lub hom phiaj tseem ceeb ntawm cov dej ntws channel
Kev taw qhia cov dej ntws ntawm cov hlau molten: Cov haujlwm tseem ceeb tshaj plaws ntawm tus neeg khiav dej num yog coj cov kub kub molten hlau kom ntws zoo thiab ua kom zoo los ntawm cov sprue mus rau hauv pwm kab noj hniav. Qhov tsim nyog txaus channel tsim tuaj yeem ua kom ntseeg tau tias cov kua hlau ua kom tsis txhob muaj kev kub ntxhov, eddies, thiab lwm yam tshwm sim thaum lub sij hawm sau cov txheej txheem, yog li txo cov roj entrainment thiab tiam ntawm inclusions, thiab txhim kho qhov zoo ntawm castings.
Tswj lub filling ceev thiab lub sij hawm: Los ntawm kev kho qhov loj, zoo, thiab kom muaj nuj nqis ntawm cov ndlwg channel, lub filling ceev thiab lub sij hawm ntawm cov hlau molten yuav precisely tswj. Ib txoj kab dav dav tuaj yeem ua kom nrawm nrawm thiab tsim nyog rau qhov loj lossis nyias-walled castings; Cov kav dej me me los yog tortuous ntws tuaj yeem ua rau qeeb qeeb, uas yog qhov muaj txiaj ntsig zoo rau kev tso pa tawm thiab qhov ntsuas kub tsis sib xws.
Ntsuas qhov ua kom siab: Hauv kev tsim cov txheej txheem castings, kev tsim cov dej ntws kuj yuav tsum tau xav txog yuav ua li cas sib npaug ntawm qhov ntim ntawm txhua qhov kab noj hniav. Los ntawm kev npaj cov dej ntws channel kom zoo, nws muaj peev xwm los xyuas kom meej tias txhua qhov kab noj hniav tau sau ib txhij los yog hauv qhov kev txiav txim ua ntej, zam qhov tshwm sim ntawm qhov tsis xws luag xws li hauv zos overheating, txias rwb thaiv tsev, los yog shrinkage.
Kho qhov kub thiab txias: Lub ntws channel kuj ua lub luag haujlwm hauv kev tswj qhov kub thiab txias thaum lub sij hawm ntws ntawm cov hlau molten. Cov dej ntws ntawm cov hlau molten hauv cov channel yuav tshem tawm qee qhov cua sov, ua rau cov cua txias ntawm cov castings ze ntawm cov channel yuav qeeb qeeb. Los ntawm kev kho qhov ntev, ntu ntu ntu, thiab cov cua txias ntawm cov dej ntws, qhov ntsuas kub ntawm qhov casting tuaj yeem tswj tau, txo qhov tshwm sim ntawm thermal stress thiab tawg.
Optimizing casting qauv: Qee zaum, kev tsim cov dej ntws kuj tuaj yeem siv los ua kom zoo dua cov qauv ntawm cov castings. Piv txwv li, thaum tsim castings nrog complex sab hauv kab noj hniav los yog reinforcing ribs, lub ndlwg xeev ntawm cov hlau molten tuaj yeem txhim kho los ntawm kev teeb tsa cov neeg khiav dej num sab hauv los yog cov chaw pabcuam kom ntseeg tau tias muaj kev ncaj ncees thiab zoo ntawm kev txhaws ntawm cov kab noj hniav thiab txhawb cov tav.
Txhim kho kev tsim khoom thiab kev siv cov khoom siv: Tsim nyog channel tsim tuaj yeem ua rau luv luv lub voj voog casting thiab txhim kho kev tsim khoom. Lub caij no, los ntawm kev ua kom zoo ntawm cov dej ntws channel, cov khib nyiab ntawm cov hlau molten thiab qhov hnyav ntawm cov sprue tuaj yeem raug txo, thiab kev siv tus nqi ntawm cov khoom siv thiab cov nqi ntawm cov castings tuaj yeem txhim kho.
3, Kev txiav txim siab rau Channel Tsim
Thaum tsim cov channel ntws, nws yuav tsum tau xav txog cov hauv qab no kom ua tiav:
Casting puab thiab loj: Txiav txim siab qhov layout thiab qhov loj ntawm cov ntws channel raws li qhov nyuaj thiab qhov loj ntawm cov casting.
Kev ua haujlwm ntawm cov kua hlau: Lub flowability, solidification yam ntxwv, thiab cov khoom thermophysical ntawm cov kua hlau sib txawv muaj feem cuam tshuam rau kev tsim channel.
Casting txheej txheem yuav tsum: nrog rau cov kev txwv ntawm casting txoj kev, pouring kub, pouring ceev thiab lwm yam txheej txheem tsis nyob rau hauv tsim ntawm ntws raws.
Economy thiab feasibility: Txo qhov nyuaj thiab raug nqi ntawm cov dej ntws channel thaum ua kom zoo ntawm cov castings.
4, Cov ntaub ntawv siv tau
Noj cov casting ntawm lub tsheb cav lub tog raj kheej blocks ua piv txwv, qhov kev tsim channel ntws yog qhov nyuaj heev thiab tseem ceeb heev. Txhawm rau kom ntseeg tau tias cov hlau molten tuaj yeem sib npaug thiab ua kom nrawm nrawm rau pwm kab noj hniav thiab tso pa tawm thiab cov khoom siv, cov neeg tsim qauv feem ntau teeb tsa ntau lub rooj vag thiab cov neeg khiav dej num rau saum lub tog raj kheej lub cev, ntsuas qhov ntsuas qhov siab thiab qhov kub thiab txias ntawm txhua lub tog raj kheej lub cev kom raug. xam thiab tswj qhov loj thiab cov duab ntawm cov neeg khiav dej num. Nyob rau tib lub sijhawm, cov kev pabcuam ntws yuav raug muab tso rau hauv lub tog raj kheej lub cev txhawm rau txhim kho qhov ua kom zoo ntawm cov kab noj hniav sab hauv. Qhov kev tsim no tsis tsuas yog txhim kho qhov zoo ntawm lub tog raj kheej lub tog raj kheej xwb tab sis kuj tseem txhim kho kev tsim khoom.
