Yuav ua li cas rau nruab pwm?
(1) ua ntej pwm txhim kho, kev npaj ua haujlwm yuav tsum tau nqa tawm mus xyuas thiab kuaj cov pwm ua ntej nruab ib txheej tshiab ntawm cov pwm ntawm kev txhaj tshuaj moulding tshuab template.
Tshawb xyuas seb qhov khoom ntim ntawm moulded molded khoom sib dhos ntim kabmob (ntim) ntawm txhaj tshuaj molding tshuab.
Cov qauv ntawm kev ntsuas lub suab ntim ntawm pwm tsim cov khoom yog raws li nram no.
V = nViVj
V - lub ntim ntawm cov khoom siv yaj yog yuav tsum tau rau lub molding ntawm ib yam khoom;
Vi - ntim pwm khov;
Vj - lub kaw lus casting thiab yuav tsum tau ntim ntawm cov sab ya;
N - cov kab noj hniav.
Cov kev sib raug zoo ntawm lub ntim ntawm lub ntim (ntim) thiab txhaj tshuaj molding tshuab (ntim) ntawm lub tshuab molding yog V tsawg tshaj 0.8vmax. Hauv cov mis, Vmax yog lub theoretical txhaj tshuaj ntim ntawm txhaj tshuaj molding tshuab.
Txheeb xyuas thiab xyuas tias cov txheej txheem pwm yuav tsum tau muaj kev sib raug zoo tshaj plaws ntawm cov pwm quab yuam thiab txhaj tshuaj molding machine.Note tias txheej txheem puab yuav tsum tau hais tias cov pwm quab yuam yuav tsum tsawg dua qhov siab tshaj plaws ntawm kev txhaj tshuaj molding tshuab, nam sis F1 tsawg tshaj 0.9fmax.
F1 <>
F1 nyob rau hauv cov formula - kev txhaj tshuaj yuav tsum tau muab sib xyaw nrog pwm, t;
A - kev nyab xeeb feem ntau, feem ntau yog ib qho = 1 ~ 1.2;
P - txhais tau tias qhov siab qhov siab, MPa;
A - lub cheeb tsam ntawm cov pwm ntawm qhov pwm, cm2.
Seb puas tau tag nrho cov tuab (qhov siab) ntawm cov pwm sib luag nrog qhov ntev ntev ntawm template.Txhob xyuas kom meej
L p H1H2 + H3
Hom H1 - ob zaug qhov siab ntawm qhov pwm txav;
H2 - qhov ntev yog 5 ~ hli0;
H3 - taag pwm qhov siab, hli.
Yuav ua li cas rau nruab pwm?
Tshawb xyuas thiab kos cov khoom ncoo uas tsim tawm hauv mould thiab kev txhaj molding, seb qhov luaj li cas yog sib npaug thiab tuaj yeem ua haujlwm.
Txawm hais tias qhov loj ntawm tus pas nrig ntawm qhov kev txhaj tshuaj molding yog loj dua qhov uas muaj cov pwm, qhov xov qhov ntawm lub qauv yog tsim rau lub pob zeb txhim kho ntawm cov pwm.
Tshawb xyuas seb qhov arc vojvoog ntawm lub qhov kawg ntawm lub nozzle yog sib phim nrog cov leeg ntawm cov khoom khov ntawm cov pwm.
Lub tes tsho nyob rau ntawm qhov kev ntsuas template matched nrog lub pwm muab lub cuab yeej ua ke.Tom qab kev sib dhos ntawm ob ntu, nws yog ib qho ua tau los xyuas kom meej tias qhov nozzle qhov yog coincident nrog lub kab nruab nrab ntawm qhov nkag kab hauv cov khoom melting.
(2) pwm kev lag luam
Los ntxuav lub rooj sib txoos ntawm cov qauv thiab cov pwm.
Kho cov haujlwm khawm ntawm txhaj tshuaj molding tshuab los kho txoj haujlwm.
Los txiav tawm ntawm kev txhaj tshuaj molding tshuab haujlwm fais fab mov.
Txheeb xyuas seb qhov phaj clamping yog ceev thiab ceev kom pwm kaw.
Qhov chaw nruab nrab ntawm qhov chaw pab cuam (qhov nqaim, hloov, roj pleev) ntawm kev kuaj thiab hom kev xeem tiav thiab ua haujlwm tau zoo.
Kom nruab rau cov pwm crane.Yog hais tias lub tonnage ntawm cov khoom siv hoisting tsis txaus, lub pwm tuaj yeem tau hoisted thiab ntsia.Thaum twg ob qhov chaw ntsia thiab tsau, daim ntawv qhia qhia thiab phau ntawv tsho yuav tsum tau siv los kho cov kev siv installation.
Lub plhaub ntawm qhov pwm yuav tsum txiav txim siab raws li txoj haujlwm ntawm qhov chaw ntawm lub qhov ntu thiab cov pwm, thiab lub mould fastening tuaj yeem siv nrog cov ntsia hlau, thiab phaj compression yuav siv nrog lub hau ntswj. ua qhov tsim nyog, qhov kev sib zog ntawm txhua tus ntsia hlau yuav tsum tau txawm tias yuav tsum tau ua rau.Kom lub pob zeb txuas ntawm cov qauv loj, yuav tsum tau them rau pwm, uas yuav tsum sib koom tes thiab sib koom tes nrog kev muaj peev xwm ntawm cov cuab yeej txhawb nqa.
