Kuumba ndondomeko ndi kuchuluka kwa prepreg mu zitsulo nkhungu patsekeke wa nkhungu, ntchito makina osindikizira ndi kutentha gwero kutulutsa ena kutentha ndi kuthamanga kuti prepreg mu nkhungu patsekeke ndi wofewetsa ndi kutentha, kuthamanga otaya, wodzaza ndi otaya, wodzazidwa ndi nkhungu patsekeke akamaumba ndi kuchiritsa mankhwala a ndondomeko njira.
Kuumba ndondomeko yodziwika ndi kufunika Kutentha mu akamaumba ndondomeko, cholinga Kutentha ndi kupanga prepreg mu kufewetsa otaya otaya.utomoni, kudzaza nkhungu ndikufulumizitsa kuchiritsa kwa matrix a resin. Panthawi yodzaza nkhungu ndi prepreg, osati matrix a utomoni okha omwe amayenda, komanso zowonjezera zowonjezera, ndipo utomoni wa matrix ndi ulusi wolimbitsa umadzaza mbali zonse za nkhungu nthawi imodzi.
Only theutomonimasanjidwewo mamasukidwe akayendedwe ndi lalikulu kwambiri, chomangira ndi wamphamvu kwambiri, kuti aziyenda ndi kulimbikitsa ulusi, kotero akamaumba kumafuna akamaumba kuthamanga kwambiri, amene amafuna zitsulo amaumba ndi mphamvu mkulu, mwatsatanetsatane mkulu ndi kukana dzimbiri, ndipo amafuna kugwiritsa ntchito makina osindikizira apadera otentha kulamulira kutentha akamaumba machiritso, kuthamanga, kugwira nthawi ndi magawo ena ndondomeko.
Kuumba njira ya dzuwa mkulu, mankhwala kukula molondola, pamwamba mapeto, makamaka kwa dongosolo zovuta za gulu zinthu zakuthupi akhoza zambiri kuumbidwa kamodzi, sikuwononga ntchito ya gulu zinthu zakuthupi. Cholakwika chake chachikulu ndikuti mapangidwe a nkhungu ndi kupanga zimakhala zovuta kwambiri, ndalama zoyambazo ndizokulirapo. Ngakhale kuti akamaumba ali ndi zofooka pamwamba, nkhungu akamaumba akadali ndi udindo waukulu mu gulu akamaumba zinthu.
1, Kukonzekera
Chitani ntchito yabwinoprepreg, akamaumba tooling zisamere pachakudya, ndi ng'anjo mayeso chidutswa cha ntchito yothandizira, ndi kuyeretsa nkhungu mu ntchito yotsalira utomoni zotsalira, zinyalala, kusunga nkhungu woyera ndi yosalala.
2, Kudula ndi kuyika kwa prepregs
Adzapangidwa kukhala mankhwala a carbon CHIKWANGWANI zopangira zokonzeka, prepreg atatha kubwereza, kuwerengera dera la zipangizo, zipangizo, chiwerengero cha mapepala, zopangira wosanjikiza ndi wosanjikiza zofukiza anawonjezera, nthawi yomweyo pa superposition wa zinthu za pre-pressure, mbamuikha mu mawonekedwe a wokhazikika, khalidwe la chiwerengero cha wandiweyani mabungwe.
3. Kuumba ndi kuchiritsa
Ikani zopangira zopangira mu nkhungu, ndipo nthawi yomweyo mu airbags pulasitiki mkati, kutseka nkhungu, lonse mu akamaumba makina, mkati pulasitiki airbags kuphatikiza kupanikizika nthawi zonse, kutentha nthawi zonse, anapereka nthawi zonse, kuti machiritso ake.
4, Kuzizira ndi kugwetsa
Patapita nthawi ya mavuto kunja nkhungu choyamba ozizira kudziwa kwa nthawi, ndiyeno kutsegula nkhungu, demolding kunja diso kuyeretsa tooling nkhungu.
5, Kukonza akamaumba
Pambuyo pogwetsa mankhwalawo ayenera kutsukidwa, ndi burashi yachitsulo kapena burashi yamkuwa kuti achotse pulasitiki yotsalira, ndikuwomba ndi mpweya woponderezedwa, mankhwala opangidwawo amapukutidwa, kuti pamwamba pakhale bwino komanso oyera.
6, Kuyesa kosawonongeka ndikuwunika komaliza
Kuyesa kosawononga ndikuwunika komaliza kwa zinthuzo kumachitika molingana ndi zofunikira za zolemba zopanga.
Kusanthula kwa mfundo zaukadaulo za prepreg molding process
Kuyambira kubadwa kwa ma carbon fiber composites, nthawi zonse amakhala ochepa chifukwa cha mtengo wopangira komanso zotsatira za kugunda kwa kupanga, ndipo sizinagwiritsidwe ntchito mochuluka. Sankhani mtengo wopangira kaboni CHIKWANGWANI ndi kugunda ndi njira akamaumba,carbon fiber kompositi zinthuakamaumba ndondomeko pali zambiri, monga RTM, VARI, otentha atolankhani akasinja, uvuni kuchiritsa prepreg (OOA), etc., koma pali botolo awiri: 1, akamaumba mkombero nthawi yaitali; 2, mtengo wake ndi wokwera mtengo (poyerekeza ndi zitsulo ndi mapulasitiki). Prepreg CompressionMolding, ngati njira yopangira, imatha kuzindikira kupanga batch ndikuchepetsa mtengo wopanga, womwe umagwiritsidwa ntchito kwambiri.
Prepreg akamaumba ndondomeko amatanthauza kutentha, kuthamanga, mu nthawi inayake adzakhala prepreg kufalikira mu chisanadze zoboola pakati psinjika akamaumba. Liwiro lowumba la njirayi ndilofulumira, zofunikira za zipangizo ndi zosavuta, zosavuta kugwiritsa ntchito, poyerekeza ndi thanki yotentha yosindikizira, VARI ndi ndondomeko ya OOA, mankhwalawa ndi abwino kwambiri pamtundu wowoneka bwino, kukhazikika kwabwino, ndondomekoyi ndi yosavuta kulamulira.
▲ Tchati chomawumba chisanadze mwana asanabadwe
Zinthu zinayi za ndondomeko yowumba
1. Kutentha ndi kufanana: kuwonetsa momwe zimakhalira pakatiutomonindiwothandizirandi yunifolomu anachita udindo, makamaka kulamulira khalidwe akamaumba pamwamba ndi kuchiritsa digiri;
2. Kupanikizika ndi kufanana: kuwonetsa kutuluka kwa mpweya ndi kutuluka kwa mpweya mu utomoni, kulamulira mawonekedwe a pamwamba ndi makina;
3. Kutalika kwa nthawi yochiritsa: kuwonetsa kuchuluka kwa machiritso, kuonetsetsa kuti ntchito ikuyenda bwino;
4. Kukhuthala kwa nkhungu: kuwonetsa makulidwe a chinthucho, malinga ndi mawonekedwe apadera a zinthu za carbon fiber, kupanga makulidwe oyenera.
Kugwiritsa ntchito njira
Prepregakamaumba ndondomeko akhoza theoretically kupanga dongosolo lililonse la mankhwala, kapangidwe mankhwala ngati zovuta kwambiri, monga inverted zomangira, kwambiri flange m'dera, chifukwa cha kuchuluka kwa mtengo wa nkhungu ndi zovuta kupanga, kotero kuti kapangidwe ka zidutswa makamaka zovuta applicability si wamphamvu, koma tikhoza kukhala kukhathamiritsa structural kapena chipika kamangidwe + chomangira njira kupanga mbali zovuta.
Zogwirizana ndi Technology
1. Ukadaulo Wodula Mitundu Yosiyanasiyana: Ma prepregs amitundu yambiri amadulidwa nthawi imodzi; prepregs okhala ndi ngodya zosiyanasiyana amadulidwa nthawi imodzi kuti apititse patsogolo kudula.
2. Tekinoloje yotentha-mkati / yotentha: nkhungu imatenthedwa mwachindunji kutentha kwa machiritso, ndipo preform imayikidwa mu nkhungu ndikukanikizidwa mu mawonekedwe, omwe amafupikitsa nthawi yopangira ndikuchepetsa mphamvu.
3. Net-size akamaumba teknoloji: preform imakhomeredwa ku kukula kwa ukonde poyamba, ndiyeno imayikidwa mu nkhungu ya kukula kwa ukonde kuchiritsa, kuchepetsa kudula.
Zovuta za Njira
Kuvuta kupanga zisankho zazinthu zovuta zamapangidwe: Ngati pali zotchinga zambiri zopindika ndi ngodya zoyipa pazogulitsa, zipangitsa kuti nkhungu zikhale zovuta kupanga, ndipo nthawi yomweyo, zisagwiritsidwe ntchito kwa nthawi yayitali, zimabweretsa kuchepa kwa kulondola kwa kulumikizana kwa malo oyikapo. Chifukwa chake, popanga chinthucho, yesetsani kupewa kupindika kapena mbali yolakwika.
Zindikirani: mbali zophimba zakunja za zinthu zomwe zimafunikira pamtundu wapamwamba ndizokwera kwambiri, kaboni CHIKWANGWANI chakuthupi mbali za mavuto wamba ndi: mankhwala mame kapangidwe mbali mawanga oyera; zovuta kapangidwe ka mankhwala; nsonga zapamtunda, kusowa kwa mavuto a guluu, ndi zina zotero. Kufotokozera mwachidule zifukwa, mankhwala ochiritsira mu prepreg sali osakanikirana mofanana kapena momwe zimakhalira sizikwanira; kutentha kwa nkhungu sikofanana; kutentha ndi kupanikizika sikuli m'malo; kapangidwe ka nkhungu ndi kukonza sizikupezeka; kuumba ndondomeko sikuyendetsedwa; nkhunguwomasuliraamachitira, ndi zina zotero.
