Thaum tsim lub dab dej kub rau cov neeg siv khoom txawv teb chaws, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov txog cov txheej txheem tsim khoom uas yuav siv los tsim nws. Feem ntau, cov dab dej kub yog tsim los ntawm extrusion, txhais tau hais tias tus qauv tsim yuav tsum sib haum nrog cov txheej txheem no. Yog tias tsis yog, lub dab dej kub yuav tsis tuaj yeem tsim tau txhua qhov, lossis nws yuav xav tau kev hloov pauv tseem ceeb uas tuaj yeem nce nqi thiab sijhawm ua haujlwm. Hauv tsab xov xwm no, peb yuav tham txog qee cov lus qhia rau kev tsim cov dab dej kub uas tuaj yeem extruded tau yooj yim thiab ua tau zoo.
Cov teeb meem tshwm sim uas tuaj yeem tshwm sim thaum lub sij hawm extrusion txheej txheem thiab yuav ua li cas zam lawv
Thaum lub sij hawm extrusion txheej txheem, muaj ob peb yam teeb meem uas yuav tshwm sim. Cov no suav nrog:
- Misalignment: Thaum lub dab dej kub tsis raug ua raws li cov extrusion tuag, nws tuaj yeem ua rau muaj teeb meem zoo xws li kev ua tiav tsis zoo, warping, thiab tawg. Txhawm rau zam qhov no, nco ntsoov xyuas qhov sib txawv ntawm koj lub dab dej kub tsim ua ntej xa mus rau ntau lawm.
- Tshuab: Yog tias huab cua ntau dhau mus rau lub dab dej kub, nws tuaj yeem ua rau cov khoom tawg tawm ntawm extrusion tuag. Qhov no tuaj yeem ua rau muaj teeb meem zoo thiab nce nqi tsim khoom. Txhawm rau zam qhov no, nco ntsoov kuaj koj lub dab dej kub tsim raws li qhov xav tau ntau lawm ua ntej xa mus rau ntau lawm.
1. Lub tswv yim rau optimizing koj lub dab dej kub tsim rau extrusion manufacturing
Lub dab dej kub tsuas yog cov cuab yeej hloov hluav taws xob uas tuaj yeem nqus tau cov cua sov kom txias rau lwm yam khoom siv thiab cov khoom siv. Cov kws tsim hluav taws xob tsim cov khoom siv hluav taws xob siv thermal tsom xam software, uas qhia cov cua sov ntws los ntawm lub kaw lus; tag nrho cov no tso cai rau lawv mus nrhiav qhov chaw kub ceev thiab nrhiav thaj chaw uas xav tau txias.
Muaj ob peb yam uas yuav tsum nco ntsoov thaum optimizing koj lub dab dej kub tsim rau extrusion:
- Xyuas kom tseeb tias lub dab dej kub ua kom zoo nrog cov extrusion tuag
- Cia nws yooj yim: Cov qauv tsim tsis yooj yim tuaj yeem tsim tau yooj yim thiab yuav ua rau muaj teeb meem zoo. Khaws koj lub dab dej kub tsim kom yooj yim li sai tau kom tsis txhob muaj teeb meem no.
- Siv cov qauv duab: Cov duab qauv yooj yim rau extrude dua li cov duab kev cai. Yog tias ua tau, siv cov qauv duab hauv koj lub dab dej kub tsim kom yooj yim rau kev tsim khoom.
- Zam cov kaum ntse ntse: cov kaum ntse ntse tuaj yeem ua teeb meem thaum txheej txheem extrusion, yog li zam lawv yog tias ua tau. Hloov chaw, siv cov fab sib npaug lossis cov chamfers kom yooj yim rau kev tsim khoom.
- Siv cov tuab tuab: yog tias ua tau, sim siv cov tuab tuab thoob plaws hauv koj lub dab dej kub tsim. Qhov no yuav ua rau nws yooj yim rau kev tsim khoom.
Los ntawm kev ua raws li cov lus qhia no, koj tuaj yeem tsim cov dab dej kub tsim uas yooj yim rau extrude thiab tsis tshua muaj teeb meem zoo. Qhov no yuav ua rau txo cov nqi tsim khoom thiab txhim kho lub sij hawm txhuas.
2. Cov yam ntxwv cuam tshuam rau kev ua haujlwm ntawm lub dab dej kub
Muaj ntau yam uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub dab dej kub. Cov no suav nrog hom khoom siv, qhov loj thiab cov duab ntawm lub dab dej kub, thiab cov cua ntws ncig nws. Tsis tas li ntawd, ib puag ncig uas lub dab dej kub ua haujlwm kuj tuaj yeem cuam tshuam rau nws qhov kev ua tau zoo. Piv txwv li, yog tias nws yog siv nyob rau hauv ib qho chaw kub thiab av noo, nws yuav tsis zoo dua yog tias nws yog siv nyob rau hauv ib qho chaw txias thiab qhuav. Los ntawm kev nkag siab txog cov xwm txheej no, koj tuaj yeem tsim cov dab dej kub uas ua kom zoo rau lawv daim ntawv thov.
3. Thermal kuj thiab thermal impedance
Thermal resistance yog ib qho kev ntsuas ntawm lub dab dej kub zoo li cas, thiab thermal impedance yog ib qho kev ntsuas ntawm qhov ua tau zoo ntawm cov cua sov hloov mus rau qhov chaw nyob ib puag ncig. Los ntawm kev nkag siab cov ntsiab lus no, koj tuaj yeem tsim cov dab dej kub uas ua kom zoo rau lawv daim ntawv thov.
4. Kub gradient nyob rau hauv lub dab dej kub.
Kub gradient yog qhov sib txawv ntawm qhov kub thiab txias ntawm ob lub ntsiab lus ntawm lub dab dej kub. Qhov no tuaj yeem siv los txiav txim siab qhov chaw zoo rau cov dab dej kub thiab lwm yam khoom siv cua txias.
Muaj ntau yam uas nkag mus rau hauv kev tsim lub dab dej kub, thiab ua raws li cov lus qhia no yuav pab koj tsim cov qauv uas yooj yim rau extrude thiab tsis tshua muaj kev cuam tshuam cov teeb meem zoo. Los ntawm optimizing koj lub dab dej kub tsim rau extrusion manufacturing, koj tuaj yeem txhim kho lub sij hawm txhuas thiab txo cov nqi tsim khoom. Yog xav paub ntxiv txog cov dab dej kub thiab lawv cov ntawv thov, thov mus saib peb lub vev xaib.
