Kukonzekera njira ndi mavuto a aluminiyamu thovu masangweji mapanelo

Kukonzekera kwamapanelo a masangweji a aluminiyamulagawidwa m'magulu awiri athunthu. Gulu loyamba ndi kukonzekera thovu zotayidwa poyamba, ndiyeno kulumikiza zotayidwa thovu ndi gulu zitsulo m'njira zosiyanasiyana, monga kugwirizana simenti, pamwamba matenthedwe kupopera mbewu mankhwalawa, ndi kuwotcherera kugwirizana. Mtundu wachiwiri ndi kukonzekera prefabricated thupi la zotayidwa thovu masangweji gulu, ndiyeno prefabricated thupi ndi kutenthedwa kuti pachimake wosanjikiza thovu, ndi thovu utakhazikika pambuyo akamaliza thovu kuti ndi aluminiyamu thovu masangweji gulu. Njira zokonzekera zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo kukanikiza kotentha - njira yopangira thovu ya ufa, kugudubuza - kupaka - kutulutsa thovu, ndi zina zotero.

1. Glued kugwirizana

Gluing imatanthawuza njira yopangira masangweji a masangweji pomanga chithovu cha aluminiyamu ku mapanelo azitsulo okhala ndi zomatira zoyenera. Njira yolumikizira imatengera kulumikizana kwakuthupi kuti ikonzekere sangweji, ndipo njirayo ili ndi maubwino a njira yosavuta komanso yolondola kwambiri yopanga. Komabe, chifukwa structural makhalidwe a mkulu porosity waaluminium thovu, kuchotsa zonyansa m'mabowo pamwamba pa chithovu cha aluminiyamu ndizolemera kwambiri; mu njira yolumikizira iyi, gululi ndi gawo lapakati limamangiriridwa pamabowo, ndipo malo enieni omangirira ndi ang'onoang'ono, zomwe zimabweretsa mphamvu yocheperako yolumikizira kapangidwe ka sangweji; zomatira zimalephera pa kutentha kwakukulu kapena m'malo owononga kwambiri, zomwe zimapangitsa kulekanitsidwa kwa gawo lapakati pa gululi ndi kuwonongeka kwa mapangidwewo.

2. Kuwotcherera kugwirizana

Njira zowotcherera zopangira masangweji a aluminium thovu amaphatikiza kuwotcherera kwa laser, kuwotcherera kwa ultrasonic torsion, ndi kulumikizana kwa brazing. Kuwotcherera kwa laser ndi kugwiritsa ntchito mphamvu zotentha kwambiri za laser kuzinthu zamagetsi ndi thovu aluminiyamu pamwamba wosanjikiza kusungunuka, kuziziritsa pambuyo pamagulu awiriwo palimodzi, malo owotcherera, ndi ndondomeko yowotcherera yomwe ikuwonetsedwa mu Chithunzi 1. Kuwotcherera kwa laser ndi kolondola kwambiri ndipo kumatha bwino wongolerani malo olumikizana osungunuka. Ngakhale njira iyi imatha kugwira ntchito mosalekeza, magwiridwe antchito ake ndi otsika, ndipo mphamvu yomangira yazinthu imakhala yotsika. Mfundo ya akupanga torsion kuwotcherera ndi kujowina awiri zipangizo pamodzi ndi akupanga mphamvu. Komabe, njirayi imafuna malo enaake owotcherera, ndipo sizingatheke kutsiriza kuwotcherera kwa malo onse omwe akuwongolera, zomwe zimalepheretsa kugwiritsa ntchito njirayi pakupanga kwenikweni. Kulumikizana kwa brazing kudzalepheretsedwa ndi wosanjikiza wopangidwa ndi thovu aluminiyamu, chifukwa chake ndikofunikira kuchotsa wosanjikiza wa oxidized, komanso mukamagwiritsa ntchito ukadaulo wa brazing popanda brazing flux mualuminiyumu ya thovumapanelo a masangweji, njira zina zotsutsana ndi dzimbiri ziyenera kuganiziridwa kuti ziteteze zinki ndi ma aloyi ena kuti zisaphatikizidwe ndi dzimbiri la aluminiyamu. Kuonjezera apo, zigawo zomwe zimagwirizanitsidwa ndi njirayi zimangokhala ndi mabowo, kotero mphamvu ya mgwirizano idzachepetsedwa.

3. Njira yopopera mankhwala pamwamba pa matenthedwe

Njira yokutira nthawi zambiri imafuna kukhazikika kwapamwamba pamwamba pa chigawocho, kotero njirayo si yoyenera kuzinthu zovuta kwambiri. Kupopera mbewu mankhwalawa ndi ukadaulo wapamwamba, womwe umazindikirika ndi mawaya osungunuka kapena ufa. Njirayi imagwiritsa ntchito jet ya mpweya kuti ifulumizitse zinthu zomwe zimasungunuka ndikuzitengera pamwamba pa chigawocho kuti chivekedwe, ndikupangitsa kuti zigawozo zikhale ndi mawonekedwe ovuta. Mwanjira iyi, gwero la kutentha nthawi zambiri ndi arc yamagetsi. Komabe, njirayi ndi yovuta kupanga mafakitale chifukwa cha zovuta za ndondomekoyi.

4. Kukanikiza kotentha - njira ya ufa zitsulo zopangidwa ndi thovu

Mwanjira iyi, ufa wosanjikiza womwe umagwiritsidwa ntchito popanga thovu umayikidwa koyamba pagulu, kenako umayikidwa mu nkhungu palimodzi, ndipo makina osindikizira a hydraulic amagwiritsidwa ntchito kukakamiza kuzizira kwa iwo, kenako zosowekazo zimasungidwa pa 450 ℃ pafupifupi 1 h ndiyeno otentha mbamuikha kupeza akusowekapo kale amene angathe kuchitidwa thovu. The preform ndiye kutenthedwa ndi thovu mu chotsekedwa nkhungu, ndi sangweji gulu amapezedwa pambuyo kuzirala. Kukhalapo kwa nkhungu munjira iyi kudzakhala ndi malire pa kukula kwa sangweji yomalizidwa ya aluminiyamu.

5. Njira yopukutira-yopaka-thovu

Njira imeneyi ndi choyambirira ufa thovu ntchito yoyenera anagubuduza njira kupanga pachimake zakuthupi, pambuyo gulu ndi prefabricated pachimake zakuthupi anagubuduza, ❖ kuyanika, kupeza akusowekapo chisanadze nsalu, thovu pambuyo kuzirala kupeza dongosolo labwino la sangweji. gulu. Njira iyi yopangira zinthu zokhala ndi mphamvu zomangika kwambiri zimatha kuzindikira kupanga kosalekeza koma zimayenera kuthana ndi zovuta ziwiri zaukadaulo: imodzi ndiyofunika kukulitsa ufa, yachiwiri ndi kuphatikiza kothandiza kwa zinthu zapakati ndi kugubuduza gulu.
