1 Kugwiritsa ntchito aloyi ya aluminiyamu mumakampani amagalimoto
Pakali pano, zoposa 12% mpaka 15% ya zotayidwa padziko lonse lapansi zimagwiritsidwa ntchito ndi makampani opanga magalimoto, ndi mayiko ena otukuka oposa 25%. Mu 2002, makampani onse aku Europe amagalimoto amadya matani opitilira 1.5 miliyoni a aluminiyamu mchaka chimodzi. Pafupifupi matani 250,000 adagwiritsidwa ntchito popanga matupi, matani 800,000 pakupanga makina otumizira magalimoto, ndi matani 428,000 owonjezera popanga magalimoto oyendetsa ndi kuyimitsidwa. Zikuwonekeratu kuti makampani opanga magalimoto akhala akugwiritsa ntchito kwambiri zida za aluminiyamu.
2 Zofunikira Zaukadaulo Pa Mapepala Osindikizira a Aluminium mu Stamping
2.1 Kupanga ndi Kufa Zofunikira pa Mapepala a Aluminium
Njira yopangira ma aluminiyamu aloyi ndi yofanana ndi ya mapepala wamba ozizira, omwe amatha kuchepetsa zinyalala ndi kutulutsa zinyalala za aluminiyumu powonjezera njira. Komabe, pali kusiyana kwa zofunikira zakufa poyerekeza ndi mapepala ozizira ozizira.
2.2 Kusunga Kwanthawi Yaitali Kwa Mapepala Aaluminiyamu
Pambuyo poumitsa ukalamba, mphamvu zokolola za mapepala a aluminiyamu zimawonjezeka, zomwe zimachepetsa kupanga kwawo m'mphepete. Mukapanga kufa, ganizirani kugwiritsa ntchito zida zomwe zimakwaniritsa zofunikira zapamwamba ndikutsimikizira kuthekera musanapange.
Mafuta otambasulira / dzimbiri oteteza mafuta omwe amagwiritsidwa ntchito popanga amakhala okhazikika. Mukatsegula pepalalo, liyenera kugwiritsidwa ntchito nthawi yomweyo kapena kutsukidwa ndikupaka mafuta musanadindike.
Pamwamba pamakhala oxidation ndipo sayenera kusungidwa poyera. Kuwongolera kwapadera (kuyika) ndikofunikira.
3 Zofunikira Zaukadaulo Pa Mapepala A Aluminium Stamping mu Welding
Njira zazikulu zowotcherera pakumanga matupi a aluminiyamu amaphatikiza kuwotcherera kukana, kuwotcherera kozizira kwa CMT, kuwotcherera kwa tungsten inert gas (TIG), kukwera, kukhomerera, ndikupera / kupukuta.
3.1 Kuwotcherera popanda Riveting kwa Aluminium Mapepala
Aluminiyamu pepala zigawo popanda riveting aumbike ndi ozizira extrusion awiri kapena kuposa zigawo za zitsulo mapepala ntchito zipangizo kuthamanga ndi zisamere pachakudya chapadera. Njirayi imapanga malo olumikizirana ophatikizidwa ndi mphamvu inayake yolimba komanso yometa ubweya. Makulidwe a mapepala olumikiza akhoza kukhala ofanana kapena osiyana, ndipo akhoza kukhala ndi zigawo zomatira kapena zigawo zina zapakati, ndi zipangizo zomwe zimakhala zofanana kapena zosiyana. Njirayi imapanga maulumikizidwe abwino popanda kufunikira kwa zolumikizira zothandizira.
3.2 Resistance Welding
Pakadali pano, kuwotcherera kwa aluminium alloy resistance nthawi zambiri kumagwiritsa ntchito njira zowotcherera zapakatikati kapena zapamwamba kwambiri. Njira yowotcherera iyi imasungunula zitsulo zoyambira mkati mwa kuchuluka kwa ma elekitirodi munthawi yochepa kwambiri kuti apange dziwe la weld,
mawanga owotcherera amazizira mwachangu kuti apange maulalo, opanda mwayi wopangira fumbi la aluminiyamu-magnesium. Ambiri mwa kuwotcherera utsi opangidwa zigwirizana okusayidi particles ku zitsulo pamwamba ndi pamwamba zosafunika. Local utsi mpweya wabwino amaperekedwa pa ndondomeko kuwotcherera mwamsanga kuchotsa particles mu mlengalenga, ndipo pali mafunsidwe ochepa a aluminiyamu-magnesium fumbi.
3.3 CMT Cold Transition Welding ndi TIG Welding
Njira ziwirizi zowotcherera, chifukwa cha kutetezedwa kwa mpweya wa inert, zimatulutsa tinthu tating'onoting'ono ta aluminium-magnesium pa kutentha kwambiri. Tinthu tating'ono ting'onoting'ono timene timatulutsa timadzi tomwe timagwira ntchito mothandizidwa ndi arc, ndikuyika chiwopsezo cha kuphulika kwa fumbi la aluminium-magnesium. Chifukwa chake, kusamala ndi njira zopewera kuphulika kwa fumbi ndi chithandizo ndizofunikira.
4 Zofunikira Zaukadaulo Pa Mapepala A Aluminium Stamping mu Edge Rolling
Kusiyanitsa pakati pa aluminium alloy m'mphepete mwa kugudubuza ndi kugudubuza m'mphepete mwachitsulo kumakhala kofunikira. Aluminiyamu ndi yocheperako kuposa chitsulo, kotero kuthamanga kwambiri kuyenera kupewedwa pakugubuduza, ndipo liwiro logudubuza liyenera kukhala lodekha, nthawi zambiri 200-250 mm/s. Kugudubuza kulikonse sikuyenera kupitirira 30 °, ndipo kugudubuza kooneka ngati V kuyenera kupewedwa.
Zofunikira pa kutentha kwa aluminium alloy rolling: Iyenera kuchitika pa kutentha kwa 20 ° C. Magawo omwe amatengedwa mwachindunji kuchokera kumalo ozizira ozizira sayenera kugwedezeka m'mphepete mwamsanga.
5 Mawonekedwe ndi Makhalidwe a Edge Rolling kwa Aluminium Stamping Sheets
5.1 Mawonekedwe a M'mphepete mwa Mapepala a Aluminium Stamping
Kugudubuzika kozolowereka kumakhala ndi masitepe atatu: kugudubuza koyamba, kugudubuza kwachiwiri, ndikugudubuza komaliza. Izi nthawi zambiri zimagwiritsidwa ntchito ngati palibe zofunikira zenizeni zamphamvu ndipo ma angles akunja a flange ndi abwinobwino.
Kugudubuzika kwa kalembedwe ka ku Europe kumakhala ndi masitepe anayi: kugudubuza koyamba, kugudubuza kwachiwiri, kugudubuza komaliza, ndi kugudubuza kofanana ndi ku Europe. Izi zimagwiritsidwa ntchito pogubuduza m'mbali zazitali, monga zophimba zakutsogolo ndi zakumbuyo. Kugudubuzika kwamitundu yaku Europe kutha kugwiritsidwanso ntchito kuchepetsa kapena kuthetsa zolakwika zapamtunda.
5.2 Mawonekedwe a Edge Rolling kwa Aluminium Stamping Sheets
Pazida zogubuduza chigawo cha aluminiyamu, nkhungu yapansi ndi chipika choyikapo ziyenera kupukutidwa ndikusungidwa pafupipafupi ndi sandpaper ya 800-1200# kuti zitsimikizire kuti palibe zinyalala za aluminiyamu zomwe zilipo.
Zifukwa 6 Zosiyanasiyana Zowonongeka Zomwe Zimayambitsidwa ndi Kugudubuzika Kwa Mapepala A Aluminium Stamping
Zomwe zimayambitsa zolakwika zomwe zimayambitsidwa ndi kugudubuza m'mphepete mwa zigawo za aluminiyamu zikuwonetsedwa patebulo.
7 Zofunikira Zaukadaulo Pakuyika Mapepala Aluminium Stamping
7.1 Mfundo Zazikulu ndi Zotsatira za Madzi Osambitsa Kudutsa kwa Aluminium Stamping Sheets
Kusamba kwamadzi kumatanthawuza kuchotsa filimu ya okusayidi yopangidwa mwachilengedwe ndi madontho amafuta pamwamba pa aluminiyamu, komanso kudzera muzochita zamakina pakati pa aluminium alloy ndi yankho la acidic, ndikupanga filimu wandiweyani wa okusayidi pamtunda. Filimu ya okusayidi, madontho amafuta, kuwotcherera, ndi zomata zomata pamwamba pa zigawo za aluminiyamu pambuyo popondaponda zonse zimakhudza. Kupititsa patsogolo kumamatira kwa zomatira ndi zowotcherera, njira yamankhwala imagwiritsidwa ntchito kuti ikhale yolumikizana kwanthawi yayitali komanso kusasunthika pamwamba, kukwaniritsa kuwotcherera bwino. Chifukwa chake, magawo omwe amafunikira kuwotcherera kwa laser, kuwotcherera kwachitsulo chozizira (CMT), ndi njira zina zowotcherera ziyenera kuchitidwa ndi madzi osamba.
7.2 Njira Yakuyendetsera Kwa Madzi Osambitsa Passivation kwa Aluminium Stamping Sheets
Chida chotsuka madzi chimakhala ndi malo ochotsera mafuta, malo ochapira madzi a mafakitale, malo odutsa, malo ochapira madzi oyera, malo oyanikapo, ndi makina otulutsa mpweya. Zigawo za aluminiyamu zomwe ziyenera kukonzedwa zimayikidwa mudengu lochapira, zokhazikika, ndikuzitsitsa mu thanki. M'matangi okhala ndi zosungunulira zosiyanasiyana, zigawozo zimatsukidwa mobwerezabwereza ndi njira zonse zogwirira ntchito mu thanki. Matanki onse ali ndi mapampu ozungulira ndi ma nozzles kuti atsimikizire kuti mbali zonse zimatsuka. Njira yothira madzi osamba ili motere: kutsitsa 1→kutsitsa 2→kutsuka madzi 2→kutsuka madzi 3→kudutsa →kutsuka 4→kutsuka 5→kutsuka madzi 6→kuyanika. Zopangira aluminiyamu zimatha kulumpha kusamba kwamadzi 2.
7.3 Kuyanika Njira Yotsukira Madzi Kudutsa Mapepala A Aluminium Stamping
Zimatenga pafupifupi mphindi 7 kuti kutentha kwa gawolo kukwere kuchokera ku firiji kufika pa 140 ° C, ndipo nthawi yochepa yochiritsa zomatira ndi mphindi 20.
Zigawo za aluminiyumu zimakwezedwa kuchokera kuchipinda kutentha mpaka kutentha kwapakati pafupifupi mphindi 10, ndipo nthawi yogwira aluminiyumu ndi pafupifupi mphindi 20. Akagwira, amazizidwa kuchokera pa kutentha kodzisungira mpaka 100 ° C kwa mphindi 7. Mukagwira, umakhazikika mpaka kutentha. Chifukwa chake, kuyanika konse kwa magawo a aluminiyamu ndi mphindi 37.
8 Mapeto
Magalimoto amakono akupita patsogolo kumayendedwe opepuka, othamanga kwambiri, otetezeka, omasuka, otsika mtengo, otsika mtengo, komanso osagwiritsa ntchito mphamvu zamagetsi. Kukula kwamakampani opanga magalimoto kumagwirizana kwambiri ndi mphamvu zamagetsi, kuteteza chilengedwe, komanso chitetezo. Ndi chidziwitso chowonjezereka cha chitetezo cha chilengedwe, zida za aluminiyamu za pepala zimakhala ndi ubwino wosayerekezeka pamtengo, luso lazopangapanga, makina ogwirira ntchito, ndi chitukuko chokhazikika poyerekeza ndi zipangizo zina zopepuka. Chifukwa chake, aloyi ya aluminiyamu idzakhala chinthu chopepuka chomwe chimakondedwa pamakampani amagalimoto.
