Carbon fiber molding txheej txheem

Views:61 Author: Tshaj Tawm Sijhawm: 2023-06-07 keeb kwm:

Muab cov pa roj carbon fiber ntau prepreg nruab nrab ntawm cov pwm sab saud thiab qis, kaw cov pwm thiab muab cov pwm tso rau ntawm lub rooj hydroforming. Tom qab ib lub sij hawm ntawm qhov kub thiab txias siab los kho cov resin, tshem tawm cov khoom carbon fiber. Lub tshuab moulding no muaj qhov zoo ntawm kev ua haujlwm siab, zoo ntawm qhov chaw, qhov tseeb qhov tseeb, thiab tsis tshua muaj kev cuam tshuam rau ib puag ncig. Nws yog tsim rau molding ntawm composite qhov chaw uas muaj zog thiab batch ntau lawm. Txawm li cas los xij, kev tsim pwm nyob rau theem pib yog qhov nyuaj thiab kev nqis peev yog siab, thiab qhov loj ntawm lub workpiece raug txwv los ntawm qhov loj ntawm cov xovxwm.

Cov txheej txheem compression molding muaj 7 cov kauj ruam hauv qab no:

1. Ntxig qhov chaw

Lub insert feem ntau yog ua los ntawm cov hlau, uas tuaj yeem ntxiv dag zog rau cov khoom, thiab cov khoom siv kho tshuab ntawm cov khoom siv cov ntxig ntxig tau zoo heev. Kuj tseem muaj cov inlays ntxiv txhawm rau muab hluav taws xob thiab thermal conductivity lossis lwm yam khoom siv rau cov khoom. Ua ntej muab qhov ntxig, nws yog qhov zoo dua rau preheat nws.

Inserts feem ntau yog muab tso rau ntawm tes, thiab qhov kev tso kawm yuav tsum yog thiab ruaj khov. Rau cov ntxig me me, pliers lossis tweezers tuaj yeem siv los nruab rau lawv. Ib qho ntxig tuaj yeem siv rau ib yam khoom, lossis ntau qhov sib txawv tuaj yeem muab tso rau. Txoj hauj lwm yuav tsum tsis txhob yuam kev lossis skewed. Lub ntxig yuav tsum ruaj khov thiab ruaj khov yog tias tsim nyog los tiv thaiv kev txav los yog tshem tawm, txwv tsis pub nws yuav tsis ua tiav. Yog tias lub hom phiaj ntawm kev siv cov ntxig tsis ua tiav, nws yuav ua rau cov khoom seem thiab txawm tias pwm puas lawm.

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, nws yuav tsum nruj me ntsis kom muaj nuj nqis, thiab cov khoom yuav tsum tau muab sib npaug rau cov pwm zawj.

3. Pwm kaw

Clamping yog muab faib ua ob kauj ruam. Ua ntej lub punch kov cov khoom, nws yuav tsum tau ceev ceev ntawm qhov siab siab (1.5-3.0MPa). Nyob rau hauv txoj kev no, lub voj voog yuav luv luv thiab cov yas hloov pauv tuaj yeem zam tau. Tom qab lub punch kov cov khoom, nws yuav tsum pib kaw maj mam. Pwm ceev, hloov mus rau kev kub siab (15-30MPa) thiab qeeb ceev, thiaj li tsis ua kom puas lub 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 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 yog hu ua tso pa tawm.

5. Khoov

Cov txheej txheem ntawm kev hloov cov khoom siv los ntawm cov kua dej mus rau ib qho nyuaj, infusible thiab insoluble lub xeev hu ua curing ntawm ib tug thermosetting resin. 6. Lub sijhawm tuav

Cov txheej txheem ntawm resin curing hauv pwm yog ib txwm nyob rau hauv qhov kub thiab txias. Lub sij hawm yuav tsum tau los ntawm qhov pib ntawm qhov kub thiab txias, pressurization, curing kom txias thiab siab txo yog hu ua lub sij hawm tuav.

6. Demolding

Cov khoom tiav yuav tsum xub siv cov cuab yeej tshwj xeeb rau unscrew txoj kev pas nrig, thiab lwm yam, thiab tom qab ntawd demould.

7. Ntxuav cov pwm
