Kev qhia luv luv ntawm carbon fiber molding txheej txheem

Views:70 Author: Linda Tshaj Tawm Sijhawm: 2022-08-18 keeb kwm:

               Compression molding yog ib qho ntawm cov qub thiab feem ntau dynamic molding txoj hauv kev tsim cov khoom sib xyaw. Nws yog ib txoj hauv kev ntxiv ib qho nyiaj ntawm premix lossis prepreg rau hauv cov pwm hlau, thiab kho nws los ntawm cua sov thiab siab. Lub ntsiab zoo ntawm cov txheej txheem compression molding yog siab ntau lawm efficiency, yooj yim mus cuag tshwj xeeb thiab automated ntau lawm thiab siab dimensional raug ntawm cov khoom, zoo repeatability, thiab lwm yam., thiab muaj peev xwm tsim cov khoom nrog complex lug nyob rau hauv ib lub sij hawm, thiab yuav ua tau loj-tsim. .

Cov kauj ruam ntawm carbon fiber compression molding txheej txheem:

1. Ntxig qhov chaw

             Inserts feem ntau yog ua los ntawm cov hlau, uas tuaj yeem txhim kho cov khoom lag luam, thiab cov khoom siv kho tshuab ntawm cov khoom siv cov khoom ntxig tau zoo heev. Tseem muaj cov inlays ntxiv rau kev faib hluav taws xob, thermal, lossis lwm yam khoom siv rau cov khoom. Preheating yog nyiam ua ntej muab tso rau.

             Qhov ntxig feem ntau yog muab tso rau ntawm tes, thiab qhov kev tso kawm yuav tsum raug thiab ruaj khov. Yog tias qhov ntxig me me, nws tuaj yeem ntsia tau nrog cov pliers lossis tweezers. Ib qho khoom siv tuaj yeem siv ib qho ntxig, lossis ntau qhov sib txawv tuaj yeem muab tso rau, nws txoj haujlwm yuav tsum tsis txhob muab tso rau hauv qhov chaw tsis raug, tsis skewed, qhov ntxig yuav tsum ruaj khov, thiab yog tias tsim nyog, nws yuav tsum tau kho kom tsis txhob txav los yog tshem tawm, txwv tsis pub nws yuav tsis raug. ua tau. Rau lub hom phiaj ntawm kev siv cov ntxig ntxig, nws yuav ua rau cov khoom seem thiab ua rau cov pwm puas.

2. Kev Pub Noj

           Qhov tseeb ntawm tus nqi pub mis yuav cuam tshuam ncaj qha rau qhov loj thiab qhov ntom ntawm cov khoom, thiab nws yuav tsum tau nruj me ntsis kom muaj nuj nqis kom uniformly ntxiv cov khoom rau hauv pwm zawj. Kev noj zaub mov kom muaj nuj nqis yog: txoj kev gravimetric, suav txoj kev thiab txoj kev ntim ntim. Txoj kev gravimetric yog qhov tseeb tab sis cumbersome, thiab feem ntau yog siv rau cov ntaub ntawv uas xav tau qhov ntev thiab nyuaj rau pub los ntawm cov txheej txheem ntim, xws li cov ntaub ntawv crumbly thiab fibrous. Txoj kev ntim tsis yog qhov tseeb raws li txoj kev gravimetric, tab sis nws yooj yim rau kev khiav lag luam thiab feem ntau yog siv rau kev ntsuas hmoov. Txoj kev suav tsuas yog siv rau pre-nias cov khoom noj.

3. Clamping

          Cov pwm clamping yog muab faib ua ob kauj ruam. Ua ntej lub punch tsis tiv nrog cov khoom siv, nws yuav tsum tsis txhob muaj qhov siab siab (1.5-3.0MPa) sai, kom lub voj voog luv luv thiab cov yas hloov pauv tuaj yeem zam tau. Tom qab lub punch tiv tauj cov khoom, nws yuav tsum pib kaw maj mam. Cov pwm ceev yuav tsum tau hloov mus rau kev kub siab (15-30MPa) thiab qeeb qeeb, kom tsis txhob muaj kev puas tsuaj rau cov ntxig thiab tso pa tawm hauv pwm.

4. Tso pa tawm

        Yuav kom tshem tawm cov huab cua, noo noo thiab volatiles nyob rau hauv cov pwm, tom qab lub pwm raug kaw, ib co yuav tsum tau qhib lub pwm rau ib lub sij hawm ntawm lub sij hawm, cov txheej txheem no hu ua pa. Kev khiav dej num yuav tsum ceev ceev, thiab nws yuav tsum ua kom tiav ua ntej cov khoom siv plasticized. Txwv tsis pub, cov khoom hardens thiab poob nws plasticity. Nyob rau lub sijhawm no, txawm tias cov pwm qhib, huab cua tsis tuaj yeem raug tso tawm, thiab txawm tias qhov kub thiab txias tau nce siab, nws tsis tuaj yeem tau txais cov khoom zoo tagnrho. Exhaust tuaj yeem txo lub sijhawm kho, thiab tuaj yeem txhim kho cov khoom siv hluav taws xob thiab hluav taws xob ntawm cov khoom.

5. Khoov

         Cov txheej txheem uas cov khoom hloov pauv los ntawm lub xeev cov dej mus rau ib qho nyuaj infusible insoluble lub xeev hu ua kev kho ntawm thermosetting resins. Qhov ceev ntawm curing yog nyob ntawm tus nqi ntawm qhov muaj pes tsawg leeg ntawm cov txheeb ze molecular loj nyob rau hauv cov resin hloov mus rau cov khoom ntawm cov txheeb ze molecular loj, uas yog, curing ceev yog txuam nrog cov qauv molecular ntawm cov resin.

6. Lub sijhawm tuav

         Cov txheej txheem ntawm kev kho cov resin hauv pwm yog ib txwm nyob rau hauv qhov kub thiab txias, thiab lub sij hawm xav tau los ntawm kev pib cua sov, pressurizing, curing kom txias thiab depressurizing yog hu ua lub sij hawm tuav. Lub sijhawm nyob hauv qhov tseem ceeb yog lub sijhawm los tswj qhov kub thiab txias, uas yog tib yam li kev kho ceev. Yog tias lub sijhawm nyob hauv lub sijhawm luv luv, uas yog, qhov ua kom txias ntxov thiab txo qhov siab yuav ua rau kev kho tsis tiav ntawm cov resin, txo cov khoom siv hluav taws xob thiab hluav taws xob ntawm cov khoom. Thaum tshav kub kub kuj. Nyob rau tib lub sij hawm, cov khoom yuav txuas ntxiv mus rau shrink thiab warp tom qab demolding.

7. Demoulding

          Demoulding feem ntau yog ua los ntawm sab saum toj (tawm) pas nrig. Rau cov khoom uas muaj kev sib sau rods los yog ib co inserts, cov cuab yeej tshwj xeeb yuav tsum tau siv los unscrew lub forming rods, thiab lwm yam., thiab ces demolding.

8. Ntxuav cov pwm

        Txij li qee cov khoom seem yuav raug tso rau hauv pwm thiab poob rau hauv lub flash thaum molding, pwm yuav tsum tau ntxuav tom qab txhua molding. Yog tias qhov adhesion ntawm pwm yog qhov muaj zog heev, nws tuaj yeem ntxuav nrog daim ntawv tooj liab, lossis tus neeg sawv cev polishing tuaj yeem siv los so nws, thiab lwm yam, tom qab ntxuav, thov tus neeg sawv cev tso rau tom ntej molding.
