Inqubo yokubumba iyinani elithile le-prepreg ku-metal mold cavity yesikhunta, ukusetshenziswa komshini wokunyathelisa ngomthombo wokushisa ukukhiqiza izinga lokushisa elithile nokucindezela ukuze i-prepreg emgodini wesikhunta ithambe ngokushisa, ukugeleza kwengcindezi, okugcwele ukugeleza, okugcwele ukubunjwa kwe-mold cavity kanye nemikhiqizo yokwelapha yendlela yenqubo.
Iinqubo yokubumbaibonakala ngesidingo sokushisisa enqubweni yokubumba, inhloso yokushisisa ukwenza ukuthambisa kwe-resin prepreg kugeleze, kugcwele isikhunta, futhi kusheshise ukusabela okuphulukisayo kwento ye-resin matrix. Ngesikhathi senqubo yokugcwalisa isikhunta nge-prepreg, hhayi kuphela i-resin matrix egelezayo, kodwa futhi nezinto eziqinisayo, kanyeinhlakai-matrix kanye nemicu eqinisayo igcwalisa zonke izingxenye zesikhunta kanyekanye.
I-resin matrix viscosity kuphela inkulu kakhulu, futhi isibopho sinamandla ngokwanele ukugeleza nemicu yokuqinisa, ngakho-ke inqubo yokubumba idinga ingcindezi enkulu yokubumba. Lokhu kudinga isikhunta sensimbi esinamandla amakhulu, ukunemba okuphezulu, nokumelana nokugqwala, futhi kudinga ukusetshenziswa komshini wokunyathelisa okhethekile oshisayo ukulawula izinga lokushisa lokubumba ukuphulukisa, ukucindezela, isikhathi sokubamba, kanye neminye imingcele yenqubo.
Indlela yokubumba yokusebenza kahle kokukhiqiza okuphezulu, ukunemba kosayizi womkhiqizo, kanye nokuqedwa kwendawo, ikakhulukazi yesakhiwo esiyinkimbinkimbi semikhiqizo eyinhlanganisela yezinto ngokuvamile ingabunjwa kanye, futhi ngeke ilimaze ukusebenza kwemikhiqizo yempahla eyinhlanganisela. Ukushiyeka kwayo okuyinhloko ukuthi ukuklama kwesikhunta nokukhiqiza kuyinkimbinkimbi, futhi ukutshalwa kwezimali kokuqala kukhulu. Nakuba inqubo yokubumba inamaphutha angenhla, isikhuntainqubo yokubumbausabambe isikhundla esibalulekile enqubweni yokubumba impahla eyinhlanganisela.
1. Ukulungiselela
Yenza umsebenzi omuhle we-prepreg, ukubumba isikhunta samathuluzi, ngesiqephu sokuhlola isithando somlilo esisekelayo, futhi uhlanze isikhunta ekusetshenzisweni kokugcina kwe-resin eyinsalela, kanye nemfucumfucu, ukugcina isikhunta sihlanzekile futhi sibushelelezi.
2. Ukusika nokubeka ama-prepregs
Izokwenziwa umkhiqizo we-carbon fiber izinto zokusetshenziswa zokusetshenziswa ezilungile, prepreg ngemuva kokudlulisa isibuyekezo, ubale indawo yezinto ezingavuthiwe, izinto zokwakha, inani lamashidi, ungqimba lwempahla eluhlaza ngongqimba lwempepho engezwe, ngasikhathi sinye ekuphakameni kwento ye-pre-pressure, icindezelwe esimweni sokujwayelekile, ikhwalithi yenombolo ethile yezinhlangano eziminyene.
3. Ukubumba nokwelapha
Faka izinto zokusetshenziswa ezinqwabelene esikhunjeni, futhi ngesikhathi esifanayo kuma-airbag epulasitiki angaphakathi, vala isikhunta, yonke into emshinini wokubumba, ama-airbag epulasitiki angaphakathi kanye nokucindezela okuthile okungaguquki, izinga lokushisa elingaguquki, setha isikhathi esingaguquki ukuze selaphe.
4. Ukupholisa nokudiliza
Ngemva kwenkathi yesikhathi ingcindezi ngaphandle isikhunta kuqala amakhaza ukwazi isikhathi esithile, bese uvula isikhunta, demolding ngaphandle kweso ukuhlanza isikhunta tooling.
5. Ukucubungula ukubumba
Ngemva kokudiliza umkhiqizo udinga ukuhlanzwa, ngebhulashi lensimbi noma ibhulashi lethusi ukuze kukhuhlwe ipulasitiki esele, futhi kuphephethwa ngomoya ocindezelweyo, umkhiqizo obunjiwe uyapholishwa, ukuze ubuso bushelelezi futhi buhlanzeke.
6. Ukuhlolwa okungonakali kanye nokuhlolwa kokugcina
Ukuhlolwa okungabhubhisi kanye nokuhlolwa kokugcina kwemikhiqizo kwenziwa ngokuvumelana nezidingo zemibhalo yokuklama.
Selokhu kwazalwaizinhlanganisela ze-carbon fibre, ehlala inqunyelwe izindleko zokukhiqiza kanye nebhithi yokukhiqiza, ayizange isetshenziswe ngobuningi. Isinqumo sezindleko zokukhiqiza i-carbon fiber kanye nokushaywa yinqubo yokubumba, inqubo yokubumba i-carbon fibre composite impahla kukhona okuningi, njenge-RTM, i-VARI, ithangi lokucindezela elishisayo, i-oven curing prepreg (OOA), njll., kodwa kunezingqinamba ezimbili: i-1, isikhathi somjikelezo wokubumba side; 2, intengo iyabiza (uma iqhathaniswa nensimbi nepulasitiki). Inqubo yokubumba ye-Prepreg, njengohlobo lwenqubo yokubumba, ingakwazi ukubona ukukhiqizwa kwe-batch futhi inciphise izindleko zokukhiqiza, ezisetshenziswa kakhulu futhi kabanzi.
