Niaj hnub no, ntau cov khoom siv roj hmab cov khoom lag luam ua rau nws tsis yooj yim rau rhuav tshem thaum lawv tsim cov khoom lag luam pwm. Li ntawd, vim li cas nws nyuaj tawm? Yuav ua li cas tiv thaiv cov teeb meem nyuaj?
Ua ntej, cia peb nkag siab txog cov laj thawj uas txwv tsis pub tso cov khoom roj hmab:
Roj hmab tuaj pwm
(1) Cov khoom siv roj hmab pwm yuav tsum yooj yim raug rhuav tshem thaum tsim qauv, 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 txuj ci kev xav tau;
(2) Cov pwm yuav tsum tswj hwm tsis tu ncua, thiab saib xyuas nws txoj kev nyiam huv, kev deformation, chaw khov kho thiab thaj chaw du.
2. Cov qauv tsis zoo ntawm cov khoom siv roj hmab. Thaum tsim cov khoom siv roj hmab, them sai sai rau lawv cov duab, cov tuab, thiab cov nyom nqes hav, uas yog lub hauv paus tseem ceeb. Thaum cov khoom lag luam raug tshem tawm ntawm qhov cub, nws yuav poob siab vim qhov txias ntawm qhov khoom, uas yuav tsim ib qho kev tuav loj ntawm cov tub ntxhais lossis tus pin, uas cuam tshuam rau demolding. Yog tias qhov tso tawm ntawm txoj kab nqes nce ntxiv, qhov kev cuam tshuam no tuaj yeem txo qis, thiab qhov tsis xws li khoom tsim kua muag vim tsis yog-qhov nqes yuav zam tau. Feem ntau, cov khoom nqes hav yog 1 ° rau 3 °.
3. Cov khoom xyaw tsis ua haujlwm, tsis muaj peev xwm ua tus neeg sawv cev thiab lub nrawm hauv cov qauv, los yog lub ntsuas kub tsis tsim nyog thiab lub sijhawm tsim qauv, ua rau lub cev tsis txaus siab; lossis cov ntsiab lus roj hmab ntau dhau hauv cov khoom siv roj hmab, cov khoom siv nrawm ntau dhau los yuav ua rau muaj kev cuam tshuam tsis yooj yim.
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 pwm qhov thiab ua rau lub zog nias. Yog tias qhov kev tuav lub siab tsis dhau thiab lub sijhawm ntev dhau, nws tseem yuav ua rau muaj qhov nce siab hauv cov kab noj hniav, uas yuav ua rau muaj kev ntxhov siab loj, uas yuav ua rau deformation ntawm qhov pwm los yog nyem ntawm cov mating qhov chaw, uas yuav ua rau demoulding ntau nyuaj.
Qhov thib ob yog cov txheej txheem demolding. Los ntawm kev txheeb xyuas cov txheej txheem demolding, cov hauv qab no txoj kev tuaj yeem siv kom tsis txhob demolding nyuaj lossis daws teeb meem demolding
1. Cov qauv pwm tsim nyog, qhov kev nruj ntawm cov pwm yuav tsum tau nce ntau li ntau tau; kev saib xyuas ntawm cov pwm yuav tsum tau nqa tawm hauv lub sijhawm, xws li kev tu (plating, Teflon txau, sandblasting), thiab lwm yam.
2. Cov txheej txheem kev tsim qauv ntawm cov khoom siv roj hmab yuav tsum yooj yim demold 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 carbon dub txhawm rau txhim kho lossis kho cov mis qub.
4. Yog tias koj tsis paub txog kev ua neeg vulcanization, koj tuaj yeem daws nws los ntawm kev nce lub sijhawm thiab kev ntsuas kub thiab txias. Rau cov khoom lag luam nrog cov txheej txheem nruj dua, yuav tsum tau them nyiaj tshwj xeeb rau cov txheej txheem demolding los txhim kho qib kev ua haujlwm ntawm cov neeg ua haujlwm demolding.
5. Tus nqi tso cai rau koj ntxiv qhov tsim nyog ntawm sab hauv tso tus neeg sawv cev rau cov khoom siv roj hmab, txo cov zaus thiab tus nqi txau tawm tus neeg sawv cev, uas tuaj yeem tiv thaiv tus neeg saib xyuas kev tso tawm kom tsis txhob tuaj yeem ua paug ntawm cov kab noj hniav, kom nws nyuaj kom pwm.
6. Siv tus nqi ntawm tus neeg sawv cev tso tawm.
