Cov txheej txheem molding yog ib qho nyiaj ntawm prepreg rau hauv cov pwm hlau qhov ntawm cov pwm, siv cov xovxwm nrog lub cua sov los tsim ib qho kub thiab siab kom cov prepreg hauv cov pwm qhov yog softened los ntawm cua sov, siab ntws, puv ntawm ntws, puv nrog cov pwm qhov molding thiab kho cov khoom ntawm ib txoj kev txheej txheem.
Cov txheej txheem molding yog tus cwj pwm los ntawm qhov xav tau cua sov hauv cov txheej txheem molding, lub hom phiaj ntawm cua sov yog ua kom cov prepreg hauv qhov softening ntawm cov dej ntws ntawmcov roj hmab, sau cov pwm qhov thiab ua kom cov tshuaj kho sai dua. Thaum lub sijhawm sau cov pwm qhov nrog prepreg, tsis yog cov resin matrix ntws xwb, tab sis kuj tseem muaj cov khoom siv txhawb nqa, thiab cov resin matrix thiab cov fibers txhawb nqa puv txhua qhov ntawm cov pwm qhov tib lub sijhawm.
Tsuas yog qhovcov roj hmabQhov viscosity ntawm cov matrix yog loj heev, qhov sib txuas yog muaj zog heev, txhawm rau kom ntws nrog cov fibers reinforcing, yog li cov txheej txheem molding xav tau lub siab molding ntau dua, uas xav tau cov pwm hlau nrog lub zog siab, qhov tseeb siab thiab kev tiv thaiv corrosion, thiab xav tau kev siv cov xovxwm kub tshwj xeeb los tswj qhov kub ntawm cov pwm kho, siab, tuav lub sijhawm thiab lwm yam txheej txheem.
Txoj kev molding muaj kev ua haujlwm siab, qhov loj ntawm cov khoom raug, qhov chaw tiav, tshwj xeeb tshaj yog rau cov qauv nyuaj ntawm cov khoom sib xyaw feem ntau tuaj yeem pwm ib zaug, yuav tsis ua puas rau kev ua haujlwm ntawm cov khoom sib xyaw. Nws qhov tsis zoo tseem ceeb yog tias kev tsim pwm thiab kev tsim khoom nyuaj dua, kev nqis peev thawj zaug loj dua. Txawm hais tias cov txheej txheem molding muaj cov qhov tsis zoo saum toj no, cov txheej txheem molding pwm tseem nyob hauv txoj haujlwm tseem ceeb hauv cov txheej txheem molding khoom sib xyaw.
1、Kev Npaj
Ua ib txoj haujlwm zoonpaj ua ntej, molding tooling pwm, nrog rau lub cub tawg sim daim ntawm kev txhawb nqa ua haujlwm, thiab ntxuav cov pwm hauv qhov kawg siv cov residual residual residue, cov khib nyiab, kom cov pwm huv thiab du.
2, Txiav thiab tso cov prepregs
Yuav ua rau cov khoom siv carbon fiber raw khoom npaj txhij, prepreg tom qab dhau qhov kev tshuaj xyuas, xam thaj tsam ntawm cov khoom siv raw, cov ntaub ntawv, tus lej ntawm cov ntawv, cov khoom siv raw txheej los ntawm txheej ntawm cov tshuaj tsw qab ntxiv, tib lub sijhawm ntawm qhov sib tshooj ntawm cov khoom siv rau qhov ua ntej-siab, nias rau hauv cov duab ntawm ib txwm muaj, qhov zoo ntawm qee qhov lej ntawm cov chaw ntom ntom.
3 、 Kev txhaj tshuaj thiab kev kho
Muab cov khoom siv raw uas tau muab sib dhos ua ke rau hauv pwm, thiab tib lub sijhawm, kaw lub pwm rau hauv lub hnab yas sab hauv, thiab muab tag nrho rau hauv lub tshuab molding, lub hnab yas sab hauv ntxiv rau qee qhov siab tas li, qhov kub tas li, teem sijhawm tas li, kom nws kho tau.
4, Txias thiab rhuav tshem
Tom qab ib lub sijhawm ntawm lub sijhawm ntawm kev siab sab nraum lub pwm thawj zaug txias paub rau ib lub sijhawm, thiab tom qab ntawd qhib lub pwm, demolding sab nraum lub qhov muag los ntxuav cov pwm tooling.
5, Kev ua molding
Tom qab demolding cov khoom yuav tsum tau ntxuav, nrog txhuam hlau lossis txhuam tooj liab kom khawb cov yas seem, thiab tshuab nrog cua compressed, cov khoom molded yog polished, kom qhov chaw du thiab huv.
6, Kev sim tsis puas tsuaj thiab kev tshuaj xyuas zaum kawg
Kev sim tsis ua puas tsuaj thiab kev tshuaj xyuas zaum kawg ntawm cov khoom raug ua raws li qhov yuav tsum tau ua ntawm cov ntaub ntawv tsim.
Kev tshuaj xyuas cov ntsiab lus ntawm kev ua prepreg molding txheej txheem
Txij li thaum yug los ntawm cov khoom siv carbon fiber, nws yeej ib txwm raug txwv los ntawm tus nqi tsim khoom thiab qhov cuam tshuam ntawm cov khoom tsim tawm, thiab tsis tau siv rau hauv ntau ntau. Txiav txim siab tus nqi ntawm cov khoom siv carbon fiber ntau thiab cov khoom siv yog cov txheej txheem molding,cov khoom siv carbon fiber sib xyawMuaj ntau yam txheej txheem molding, xws li RTM, VARI, cov thoob dej kub, qhov cub kho prepreg (OOA), thiab lwm yam, tab sis muaj ob qhov teeb meem: 1, lub sijhawm molding ntev; 2, tus nqi kim (piv rau cov hlau thiab yas). Prepreg CompressionMolding, ua ib hom txheej txheem molding, tuaj yeem ua tiav ntau lawm thiab txo cov nqi tsim khoom, uas siv ntau dua thiab dav dua.
Cov txheej txheem prepreg molding yog hais txog qhov kub thiab txias, siab, thiab thaum lub sijhawm twg los tau, prepreg yuav kis mus rau hauv lub cev ua ntej pwm. Qhov ceev molding ntawm cov txheej txheem no yog ceev, cov khoom siv xav tau yooj yim, yooj yim rau kev khiav lag luam, piv rau lub tank kub nias, VARI thiab OOA, cov khoom zoo heev hauv ob qho tib si qhov zoo ntawm qhov chaw, qhov ruaj khov zoo, thiab cov txheej txheem yooj yim los tswj.
▲ Daim ntawv qhia txog cov txheej txheem ua ntej-preg molding
Plaub yam ntawm cov txheej txheem molding
1. Kub thiab sib xws: qhia txog qib kev ua haujlwm ntawmcov roj hmabthiabtus neeg sawv cev khothiab qhov sib xws ntawm qhov chaw ua haujlwm, feem ntau tswj qhov zoo ntawm qhov molding nto thiab qib kho;
2. Kev siab thiab kev sib xws: cuam tshuam cov cua tawm thiab cov nyhuv ntws hauv cov resin, tswj qhov zoo ntawm qhov chaw molding thiab cov khoom siv kho tshuab;

4. Qhov tuab ntawm cov pwm: qhia txog qhov tuab ntawm cov khoom, raws li cov yam ntxwv tshwj xeeb ntawm cov khoom siv carbon fiber nws tus kheej, tsim kom muaj qhov tuab ntawm cov pwm.
Kev siv tau ntawm cov txheej txheem
PrepregCov txheej txheem molding tuaj yeem ua tau txhua yam qauv ntawm cov khoom, yog tias cov qauv khoom nyuaj dhau, xws li lub buckle tig rov qab, thaj tsam flange ntau dhau, ua rau tus nqi pwm nce ntxiv thiab muaj teeb meem ntau lawm, yog li rau cov qauv ntawm cov khoom nyuaj tshwj xeeb, kev siv tsis muaj zog, tab sis peb tuaj yeem ua kom zoo dua lossis tsim cov khoom sib txuas + kev daws teeb meem los tsim cov khoom nyuaj.
Kev Siv Tshuab Sib Xws
1. Kev Siv Tshuab Txiav Ntau Txheej: Cov prepregs ntau txheej raug txiav ib zaug; cov prepregs nrog cov ces kaum sib txawv raug txiav ib zaug kom txhim kho kev txiav zoo.
2. Kev siv tshuab kub-hauv/kub-tawm: lub pwm raug cua sov ncaj qha mus rau qhov kub kho, thiab lub preform raug muab tso rau hauv lub pwm thiab nias rau hauv cov duab, uas ua rau lub sijhawm molding luv dua thiab txo kev siv hluav taws xob.
3. Kev siv tshuab molding loj: lub preform raug punched kom loj ua ntej, thiab tom qab ntawd muab tso rau hauv lub pwm loj rau kev kho, txo cov txheej txheem txiav.
Cov Teeb Meem ntawm Cov Txheej Txheem
Qhov nyuaj hauv kev tsim cov pwm rau cov khoom lag luam uas muaj cov qauv nyuaj: Yog tias muaj ntau lub buckles thiab cov ces kaum tsis zoo hauv cov khoom, nws yuav ua rau cov pwm nyuaj rau tsim, thiab tib lub sijhawm, tom qab cov pwm siv ntev, nws yuav ua rau qhov kev ua haujlwm ntawm qhov chaw ntawm cov ntxig txo qis. Yog li ntawd, thaum tsim cov khoom, sim zam lub buckle tig rov qab lossis lub kaum sab xis tsis zoo.
Lus Cim: qhov yuav tsum tau ua kom zoo ntawm cov khoom siv carbon fiber ntau heev, cov teeb meem feem ntau yog: cov khoom siv dew texture feem ntau muaj cov pob dawb; cov teeb meem ntawm cov khoom siv tsis zoo; qhov chaw pinholes, tsis muaj kua nplaum, thiab lwm yam. Yog xav paub ntxiv, cov tshuaj kho hauv prepreg tsis sib xyaw lossis cov tshuaj tiv thaiv tsis tiav; qhov kub ntawm pwm tsis sib xws; qhov kub thiab siab tsis nyob hauv; kev tsim pwm thiab kev ua pwm tsis nyob hauv; cov txheej txheem molding tsis raug tswj; pwmtus neeg sawv cev tso tawmreacts, thiab lwm yam.
