Tam sim no, thaum cov khoom siv roj hmab ntau cov khoom lag luam tsim cov khoom lag luam pwm, nws tsis yooj yim los tso pwm. Yog li vim li cas nws thiaj li nyuaj los lawb tawm? Yuav ua li cas tiv thaiv cov teeb meem ntawm kev sib tw nyuaj?
Ua ntej, cia peb nkag siab txog cov laj thawj uas txwv tsis pub tso cov khoom roj hmab:
1. Cov khoom lag luam roj hmab pwm
(1) Cov khoom siv roj hmab pwm yuav tsum yooj yim raug rhuav tshem thaum tsim qauv, nws yuav tsum ua raws li cov contour thiab cov qauv ntawm cov khoom siv roj hmab, cov qauv yuav tsum yooj yim, tsim nyog, yooj yim rau kev khiav lag luam thiab ua tau raws li cov cuab yeej xav tau;
(2) Cov pwm yuav tsum tswj xyuas kom tsis tu ncua, thiab saib nws txoj kev huv, kev deformation, muab tso rau qhov chaw ruaj, thiab thaj chaw du.
2. Cov qauv ntawm cov khoom siv roj hmab tsis haum. Thaum tsim cov khoom siv roj hmab, them sai sai rau nws cov duab, tuab, thiab pwm tso txoj kab nqes, thiab pwm tawm ntawm txoj kab nqes yog qhov tseem ceeb tshaj. Tom qab cov khoom tawm los ntawm lub qhov cub, nws yuav thim centripetally vim yog qhov txias ntawm cov khoom, uas yuav ua rau muaj kev tuav loj ntawm cov tub ntxhais lossis tus pin, uas yuav tabkaum demolding. Yog tias qhov tso tawm txoj kab nqes nce ntxiv, qhov kev cuam tshuam no tuaj yeem txo qis, thiab qhov tsis xws li lub kua muag ntawm cov khoom vim tsis muaj qhov nqes hav yuav zam tau. Feem ntau, cov khoom nqes hav yog 1 ° rau 3 °.
3. Cov khoom lag luam uas tsis tsim nyog Kev tsis txaus siab rau tus neeg saib xyuas thiab ua kom nrawm rau hauv cov qauv, los yog cov khoom tsis muaj lub peev xwm ntsig txog vulcanization thiab lub sijhawm tsim, ua rau tsis muaj kev cuam tshuam; los yog ntau dhau ntawm cov roj hmab cov ntsiab lus ntawm cov roj hmab, cov khoom siv nrawm ntau dhau vulcanizing agent, thiab lwm yam kuj tseem yuav ua rau pwm tso tawm nyuaj.
4. Cov txheej txheem ntau lawm Hauv kev tsim cov txheej txheem ntawm cov roj hmab moulded khoom, txhaj tshuaj siab, tuav siab, ntsuas kub, vulcanization sijhawm, thiab lwm yam tseem yuav cuam tshuam qhov yooj yim ntawm demolding. Piv txwv li, yog tias txhaj tshuaj siab dhau dhau lawm, nws yuav ua rau elastic deformation ntawm cov pwm thiab ua rau cov nyem nyem. Yog tias qhov kev tuav lub siab tsis dhau thiab lub sijhawm ntev dhau, nws tseem yuav ua rau lub siab nyob rau hauv cov pwm kab noj hniav kom nce ntxiv, uas ua rau muaj kev ntxhov siab loj, uas yuav ua rau deformation ntawm qhov pwm los yog Flashing tshwm sim ntawm cov mating qhov chaw, ua rau demolding nyuaj dua.
Thib ob yog txoj kev demolding. Los ntawm kev ntsuam xyuas ntawm cov ntsiab lus demolding, peb tuaj yeem siv cov hauv kev hauv qab no kom tsis txhob muaj teeb meem demolding nyuaj lossis daws cov teeb meem demolding nyuaj.
1. Cov qauv pwm tsim nyog, thiab kev nruj ntawm cov pwm yuav tsum tau txhim kho kom ntau li ntau tau; kev saib xyuas ntawm lub pwm yuav tsum tau ua kom raws sijhawm, xws li ntxuav (plating, txau ntawm PTFE, sandblasting), thiab lwm yam.
2. Cov qauv tsim ntawm cov khoom siv roj hmab yuav tsum yooj yim rhuav thiab muaj txoj kab nqes txaus.
3. Xaiv cov qauv tsim nyog thiab tsim nyog viscosity. Tshaj tawm cov txheej txheem vulcanization, tshwj xeeb tshaj yog cov khoom siv roj hmab, nce tus nqi nrawm; ntxiv cov roj carbon dub kom ntxiv dag zog lossis kho cov mis qub.
4. Yog hais tias vulcanization tsis tau paub, nws tuaj yeem daws los ntawm kev nce lub sijhawm vulcanization thiab qhov ntsuas kub ntawm vulcanization; rau cov khoom lag luam nrog cov qauv tsim dua, tshwj xeeb yog them rau cov txheej txheem demolding los txhim kho qib kev ua haujlwm ntawm cov neeg ua haujlwm demolding.
5. Tus nqi tso cai, koj tuaj yeem ntxiv qhov tsim nyog ntawm kev tso tawm sab hauv mus rau cov khoom siv roj hmab, txo cov zaus thiab cov pwm tso tawm tus neeg muab tshuaj tsuag txau, uas tuaj yeem tiv thaiv tus neeg saib xyuas khoom kom tsis txhob tuaj yeem ua paug ntawm cov pwm kab noj hniav, uas ua rau nyuaj los lo pwm.
6. Siv tus nqi ntawm tus neeg sawv cev tso tawm.
