Hauv kev tsim cov khoom yas, phab ntsa thickness ntawm ib feem yog thawj qhov yuav tsum tau xav txog, phab ntsa thickness ntawm ib feem txiav txim siab cov khoom siv ntawm qhov, qhov zoo ntawm qhov, qhov peev xwm txhaj tshuaj ntawm qhov thiab tus nqi. ntawm qhov.Nws tuaj yeem hais tau tias kev xaiv thiab tsim ntawm phab ntsa thickness ntawm ib feem txiav txim siab qhov kev vam meej lossis tsis ua tiav ntawm qhov tsim ib feem.
Ntu phab ntsa thickness yuav tsum yog nruab nrab
Vim yog cov yam ntxwv ntawm cov khoom siv yas thiab cov txheej txheem txhaj tshuaj,cov phab ntsa thickness ntawm cov yas yuav tsum nyob rau hauv ib tug haum ntau yam, tsis dhau nyias, thiab tsis heev tuab.
Yog hais tias phab ntsa thickness yog nyias, cov khoom raug txhaj tshuaj thaum lub ndlwg ntawm tsis kam, yas yaj yog ib qho nyuaj rau sau tag nrho cov kab noj hniav, yuav tsum tau ntau dua kev txhaj tshuaj cov cuab yeej kom tau ntau dua filling ceev thiab txhaj tshuaj.
Yog cov phab ntsa tuab heev, qhov chaw txias lub sij hawm nce (raws li kev txheeb cais, cov phab ntsa thickness nce 1 zaug, lub sij hawm txias nce 4 zaug), qhov chaw molding voj voog nce, qhov ntau lawm efficiency yog tsawg;Nyob rau tib lub sijhawm, cov phab ntsa tuab tuab heev yog ib qho yooj yim ua rau qhov chaw tsim cov shrinkage, porosity, warpage thiab lwm yam teeb meem zoo.
Cov ntaub ntawv yas sib txawv muaj cov kev cai sib txawv rau cov phab ntsa uas tsim nyog ntawm cov khoom yas, thiab txawm tias cov chaw tsim khoom yas sib txawv ntawm cov khoom siv yas kuj tseem muaj qhov sib txawv ntawm cov phab ntsa tuab.Feem ntau siv cov khoom siv yas ntawm qhov tsim nyog phab ntsa tuab yog qhia hauv Table 1-1.Thaum cov phab ntsa tuab ntawm cov khoom yas ze rau sab sauv thiab sab qis ntawm cov phab ntsa thickness tsim nyog, cov khoom tsim engineer yuav tsum nrhiav tswv yim los ntawm cov chaw tsim khoom yas.
Table 1-1 Phab ntsa thickness xaiv rau cov khoom yas
(unit: hli)
Yam tseem ceeb uas txiav txim siab ntawm phab ntsa thickness ntawm cov yass:
1) Txawm hais tias lub zog ntawm cov qauv ntawm qhov txaus txaus.Feem ntau hais lus, lub thickness ntawm phab ntsa, qhov zoo dua lub zog ntawm ib feem.Tab sis cov phab ntsa thickness ntawm qhov ntau tshaj ib tug tej yam ntau yam, vim shrinkage thiab porosity thiab lwm yam teeb meem zoo, nce phab ntsa thickness ntawm qhov chaw yuav es tsis txhob txo lub zog ntawm qhov chaw.
2) Cov khoom tuaj yeem tiv taus lub zog ejection thaum molding.Yog hais tias ib feem yog nyias, nws yuav yooj yim deformed los ntawm ejection.
3) Muaj peev xwm tiv thaiv lub zog nruj thaum sib dhos.
4) Thaum muaj cov hlau ntxig, lub zog nyob ib puag ncig ntawm qhov ntxig yog txaus.General hlau ntxig thiab cov khoom siv yas nyob ib puag ncig shrinkage tsis sib xws, yooj yim los tsim kev ntxhov siab concentration, tsis muaj zog.
5) Lub peev xwm ntawm qhov chaw kom sib npaug ntawm qhov cuam tshuam rau qhov lawv raug.
6) Txawm hais tias lub zog ntawm lub qhov yog txaus, lub zog ntawm lub qhov yog yooj yim txo vim muaj kev cuam tshuam ntawm fusion cim
7) Nyob rau hauv qhov chaw ua tau raws li cov kev cai saum toj no, thiab kev txhaj tshuaj molding yuav tsis tsim cov teeb meem zoo, cov phab ntsa tuab ntawm cov khoom yas yuav tsum me me li sai tau, vim tias cov phab ntsa tuab tuab yuav tsis tsuas yog nce cov khoom siv thiab qhov hnyav. qhov, tab sis kuj txuas mus rau ib feem molding voj voog, yog li nce nqi ntau lawm.Daim duab 1-3 qhia txog kev sib raug zoo ntawm phab ntsa tuab thiab lub sijhawm txias rau ib feem ntawm ABS yas.
Txhawm rau kom ntseeg tau thiab txhim kho lub zog ib feem, cov khoom tsim qauv engineers feem ntau nyiam xaiv cov phab ntsa tuab tuab.
Qhov tseeb, nws tsis yog txoj hauv kev zoo tshaj plaws los xyuas kom meej thiab txhim kho ib feem ntawm lub zog los ntawm kev xaiv cov phab ntsa tuab tuab.Ib feem lub zog tuaj yeem txhim kho los ntawm kev ntxiv dag zog, tsim qauv nkhaus lossis wavy ib feem profiles, thiab lwm yam. Qhov no tsis tsuas yog txo cov khoom pov tseg ntawm ib feem, tab sis kuj ua rau lub sijhawm txhaj tshuaj molding lub voj voog ntawm lub sijhawm.
Uniform phab ntsa thickness ntawm qhov chaw
Qhov zoo tshaj plaws phab ntsa thickness tis ntawm qhov chaw yog nyob rau hauv ib qho kev sib tshuam ntawm cov seem ntawm uniform thickness.Qhov tsis sib xws ntawm phab ntsa tuab tuaj yeem ua rau qhov tsis sib xws ntawm qhov cua txias thiab qhov shrinkage ntawm qhov chaw, uas ua rau lub ntsej muag shrinkage, sab hauv porosity, warpage thiab deformation ntawm ib feem, qhov tseeb qhov tseeb yog qhov nyuaj los xyuas kom meej qhov tsis xws luag.
Piv txwv ntawm cov khoom yas uas muaj cov phab ntsa tuab tsim muaj nyob hauv daim duab 1-4.
Yog tias qhov tsis sib xws ntawm phab ntsa thickness tsis tuaj yeem ua tau, ces tsawg kawg yuav tsum tau ua kom ntseeg tau tias cov phab ntsa tuab thiab nyias phab ntsa ntawm kev hloov pauv, kom tsis txhob muaj kev hloov pauv ntawm cov phab ntsa thickness.Kev hloov pauv sai ntawm cov phab ntsa tuab ntawm cov khoom cuam tshuam rau qhov ntws ntawm cov yas yaj, yooj yim los tsim cov cim kev ntxhov siab nyob rau sab nraum qab ntawm cov yas, cuam tshuam rau qhov zoo ntawm cov khoom;nyob rau tib lub sij hawm yooj yim ua rau muaj kev ntxhov siab concentration, txo lub zog ntawm cov khoom yas, ua rau nws nyuaj rau cov khoom kom tiv taus cov khoom thauj lossis kev cuam tshuam sab nraud.
Plaub ntu ntawm phab ntsa tuab ntawm cov phab ntsa tsis sib luag tsim raws li pom hauv daim duab 1-5.
Qhov phem tshaj phab ntsa thickness tsim yog qhia nyob rau hauv a), qhov twg muaj ib tug ntse hloov nyob rau hauv lub phab ntsa thickness ntawm ib feem;
Zoo dua phab ntsa thickness tsim yog pom nyob rau hauv daim duab b) thiab c), phab ntsa thickness ntawm lub nyias phab ntsa hloov pauv, feem ntau, qhov ntev ntawm qhov kev hloov ntawm cheeb tsam yog peb zaug ntawm thickness;
Qhov zoo tshaj plaws phab ntsa thickness tsim yog qhia nyob rau hauv d), tsis yog tsuas yog ib feem ntawm phab ntsa thickness du kev hloov, tab sis kuj nyob rau hauv lub phab ntsa thickness siv lub hollow tsim, tsis tsuas yog los xyuas kom meej tias ib feem tsis ntsws, tab sis kuj los xyuas kom meej lub zog ntawm cov khoom.
