KEV LOM ZEM CASTING FOUNDRY

OEM Mechanical thiab Kev Lag Luam Kev Lag Luam

Dab Tsi Yav Tom Ntej Pob Zeb Nrig Ntsiav Yuav Tsum Ua

Raws li cov txheej txheem tsim khoom lag luam nrog keeb kwm ntawm 6000 xyoo, cov cuab yeej casting tsis yog tsuas yog muaj keeb kwm ntev, tab sis tib lub sij hawm nws tau nqus cov thev naus laus zis tshiab, cov ntaub ntawv tshiab thiab cov txheej txheem tshiab tsim nyob rau hauv kev kawm niaj hnub hauv lub sijhawm. Peb muaj lub luag haujlwm kom ua tiav cov txheej txheem kev tsim khoom lag luam no tom ntej. Cov ntsiab lus hauv qab no yog qee qhov peb xav rau yav tom ntej kev nthuav dav ntawm cov txheej txheem xuab zeb casting.

1 Foundry technology yog tsim rau kev txuag hluav taws xob thiab txuag khoom
Hauv cov txheej txheem tsim ntau lawm, ntau qhov kev siv lub zog siv nyob rau hauv cov txheej txheem hlau. Nyob rau tib lub sijhawm, qhov kev thov rau cov khoom siv tau nyob hauv cov xuab zeb casting txheej txheem kuj zoo kawg. Yog li no, yuav ua li cas kom zoo dua txuag hluav taws xob thiab cov ntaub ntawv yog qhov teeb meem tseem ceeb ntsib xuab zeb casting nroj. Cov kev ntsuas nquag siv nrog suav nrog:
1) Txais yuav cov xuab zeb molding, cov ua tseem ceeb-thev naus laus zis thiab khoom siv. Hauv cov xuab zeb casting tsim cov txheej txheem, kev kub siab, kev tiv thaiv kev ntsuas qis, kev txhaj tshuaj thiab cua xuas nrig ntaus yuav tsum siv kom ntau li ntau tau. Thiab kom deb ntawm kev siv tus kheej tawv xuab zeb, ploj ua npuas ncauj casting, nqus nqus thiab casting tshwj xeeb (xws li peev txheej, hlau pwm casting) thiab lwm yam thev naus laus zis.
2) Xuab zeb rov qab thiab rov siv dua. Thaum nrum cov khoom siv hlau tsis muaj hlau, cov hlau ua haujlwm thiab cov hlau castings, raws li qhov ntsuas kub ntawm cov xuab zeb, qhov rov ua haujlwm ntawm kev rov ua dua qub cav qub qub qub tuaj yeem ncav cuag 90%. Ntawm lawv, kev sib xyaw ntawm cov xuab zeb rov qab thiab cov dej ntub rov qab yog qhov zoo tshaj plaws thiab tus qauv siv tau.
3) Kev ua kom zoo ntawm cov nplaum. Piv txwv, yog tias qhov cuam yog de-cored los ntawm cov qauv qhuav thiab cov nplaum tseem nyob hauv cov xuab zeb, cov txheej txheem tsim nyog tuaj yeem ua rau cov nplaum rov qab siv dua, yog li txo cov nqi ntawm cov nplaum.
4) Kev kho dua tshiab ntawm cov pwm thiab cov khoom siv pwm.

2 Tsawg muaj kuab paug lossis txawm tsis muaj kuab paug
Cov xuab zeb casting foundry ua ntau cov dej khib nyiab, cov roj pov tseg thiab cov hmoov av thaum lub sijhawm ua haujlwm. Yog li no, lub hauv paus tsis yog tsuas yog lub zog siv hluav taws xob ntau, tab sis kuj muaj cov pa phem ntau. Tshwj xeeb tshaj yog nyob hauv Suav Teb, cov pa phem nyob hauv cov hauv paus yog qhov hnyav dua li lwm lub tebchaws. Ntawm lawv, cov hmoov av, huab cua thiab cov khib nyiab tawm ntawm cov xuab zeb casting nroj yog qhov hnyav tshaj plaws. Tshwj xeeb nyob rau xyoo tas los no, Tuam Tshoj txoj cai tiv thaiv kev tiv thaiv ib puag ncig muaj ntau dua thiab nruj dua, thiab cov neeg tsim tsa tau tau siv txoj hauv kev los tswj kev ua qias tuaj. Txhawm rau kom muaj kev ua tiav ntsuab thiab huv si ntawm kev tso cov xuab zeb, yuav tsum siv txoj hlua khi ntsuab kom ntau li ntau tau, lossis tsawg dua lossis tsis pub siv txoj hlua khi. Ntawm cov xuab zeb casting txheej txheem tam sim no koom nrog, ploj ua npuas ncauj casting, V txheej txheem casting thiab sodium silicate xuab zeb casting yog tus phooj ywg zoo ib puag ncig. Vim tias ploj ua npuas ncauj casting thiab V txheej txheem casting siv cov qauv xuab zeb qhuav uas tsis xav tau cov hlua khi, thaum sodium silicate sand casting siv cov organic khi.

3 Muaj qhov loj me thiab qhov loj thiab ntsuas qhov tseeb ntawm cov nruas
Nrog rau kev txhim kho qhov tseeb txoj kev ua cov txheej txheem ntawm kev nrum ntswj, qhov sib txawv ntawm cov qauv gemometical thiab qhov loj thiab dav ntawm kev ua ib feem yog tsim los ntawm ze qhov qauv tsim kom tau net qauv forminig, uas yog, yuav luag tsis muaj cov npoo ua. Qhov sib txawv ntawm qhov casting dawb thiab seem uas yuav tsum tau txais me dua thiab tsawg dua. Tom qab qee qhov chaw tsis muaj lub cim, lawv tau txav mus rau lossis tau mus txog qhov kawg thiab qhov loj thiab qhov me, thiab tuaj yeem sib sau ncaj qha tom qab sib tsoo.

4 Tsawg dua los sis tsis muaj qhov tsis xws luag
Lwm qhov taw qhia ntawm casting roughness thiab seem sib sau qib yog tus lej, qhov loj thiab kev puas tsuaj ntawm casting tsis xws luag. Vim tias cov txheej txheem kub ua haujlwm thiab cov hlau nrum txheej txheem yog qhov nyuaj heev thiab cuam tshuam los ntawm ntau yam, ua rau cov ntsiab lus tsis yooj yim yog kev zam. Txawm li cas los xij, qee qhov lossis tsis muaj qhov tsis xws luag yog yav tom ntej kev sib tw. Nws muaj ntau yam kev ntsuas zoo:
1) Txais cov thev naus laus zis los ua kom qhov ntom ntawm cov qauv hlau thiab nteg lub hauv paus kom tau txais cov ua suab nrov.
2) Siv casting simulation software txhawm rau sim tseeb cov txheej txheem casting nyob rau theem tsim ua ntej. Raws li kev sim ua tiav, cov txheej txheem tsim tau zoo rau kom paub qhov ua tiav ntawm kev ua ib zaug molding thiab pwm kev sim.
3) Ua kom cov txheej txheem tshuaj xyuas thiab ua haujlwm nruj me ntsis raws li cov lus qhia ua haujlwm tau txiav txim siab.
4) Ua kom muaj zog uas tsis muaj qhov kev tshuaj ntsuam nyob rau hauv cov txheej txheem ntau lawm, nrhiav cov txheej txheem ntawm cov txheej txheem nyob rau lub sijhawm thiab coj los ntsuas kev ntsuas kho kom zoo dua qub thiab txhim kho.
5) Xam pom qhov muaj nuj nqi tseem ceeb los ntawm kev tshawb fawb thiab kev soj ntsuam kev nyab xeeb thiab kev ntseeg tau ntawm cov seem.

5 Lub teeb yuag ua haujlwm ntawm kev ua kom pov.
Hauv kev tsim cov tsheb thauj neeg nrog caij, tsheb thauj khoom, thiab lwm yam khoom siv thauj mus los, yuav ua li cas thiaj li txo qhov hnyav ntawm qhov seem thaum ua kom lub zog ntawm cov seem yog qhov tseeb qhia ntxiv. Muaj ob lub ntsiab lus kom ua tiav los hnyav. Ib qho yog siv cov khoom siv lub teeb nyoos, thiab lwm qhov yog los txo qhov hnyav ntawm qhov los ntawm cov qauv kev teeb tsa ntawm qhov ntawm. Vim tias cov xuab zeb castings muaj kev yoog raws hauv cov qauv tsim, thiab tseem muaj ntau yam tsoos thiab tshiab hlau cov ntaub ntawv rau xaiv los ntawm, cov xuab zeb casting tuaj yeem ua lub luag haujlwm loj hauv cov khoom tsim hluav taws xob.

6 Kev thov ntawm cov thev naus laus zis tshiab xws li 3D luam ntawv hauv kev tsim pwm
Nrog rau kev txhim kho thiab kom loj hlob ntawm 3D luam ntawv thev naus laus zis, nws tseem yog qhov ntau thiab ntau dua dav siv hauv cov khoom siv casting. Piv nrog rau kev txhim kho pwm qub, 3D tshuab luam ntawv tuaj yeem tsim cov pwm uas xav tau ntawm tus nqi qis. Raws li lub tshuab ua qauv tiv thaiv sai, 3D luam ntawv tuaj yeem muab tag nrho cov kev ua si rau nws qhov zoo hauv cov qauv kev sim mus sib hais thiab cov theem me me ntawm kev cuam.
