1 Ukusetyenziswa kwe-aluminium alloy kushishino lweemoto
Ngoku, ngaphezu kwe-12% ukuya kwi-15% yokusetyenziswa kwe-aluminiyam yehlabathi kusetyenziswa lishishini leemoto, kumazwe athile aphuhlileyo angaphezulu kwe-25%. Ngo-2002, lonke ishishini leemoto laseYurophu lasebenzisa ngaphezulu kwe-1.5 yezigidi zeetoni ze-aluminiyam yealloyi ngonyaka. Malunga nama-250,000 eetoni zeemetric ezisetyenziselwe ukwenziwa kwemizimba, iitoni ezingama-800,000 zeemetric zokwenziwa kwenkqubo yothumelo lweemoto, kunye neetoni ezingama-428,000 ezongezelelweyo zokwenziwa kwenkqubo yezithuthi kunye neenkqubo zokunqunyanyiswa. Kuyacaca ukuba ishishini lokuvelisa iimoto liye laba ngumthengi omkhulu wezinto ze-aluminium.
IiMfuno ezi-2 zobuGcisa kwiiStampu zeAluminiyam kwiSitampu
2.1 IiMfuno zokuSebenza kunye noKufa kuMashithi eAluminiyam
Inkqubo yokwenza i-aluminium alloy ifana namaphepha aqhelekileyo abandayo, kunye nokwenzeka kokunciphisa inkunkuma kunye nokuveliswa kwe-aluminium scrap ngokudibanisa iinkqubo. Nangona kunjalo, kukho umahluko kwiimfuno zokufa xa kuthelekiswa namaphepha aqengqelekayo abandayo.
2.2 UGcino Lwexesha elide lweeAluminiyam Sheets
Emva kokuqina kokuguga, amandla esivuno samaphepha e-aluminiyam ayanda, anciphisa ukwenziwa kwawo komda. Xa usenza ukufa, cinga ukusebenzisa imathiriyeli ehlangabezana neemfuno ezichaziweyo eziphezulu kwaye wenze isiqinisekiso sokwenzeka ngaphambi kokuveliswa.
I-oyile eyolulayo / i-oyile yokuthintela i-rust esetyenziselwa ukuveliswa iyakwazi ukuguquguquka. Emva kokuvula iphepha lokupakisha, kufuneka lisetyenziswe ngokukhawuleza okanye licocwe kwaye lifakwe i-oyile ngaphambi kokunyathela.
Umphezulu uthambekele kwi-oxidation kwaye akufanele igcinwe kwindawo evulekileyo. Ulawulo olukhethekileyo (ukupakishwa) luyafuneka.
IiMfuno ezi-3 zobuGcisa kwi-Aluminium Stamping Sheets kwi-Welding
Iinkqubo eziphambili ze-welding ngexesha lokuhlanganiswa kwemizimba ye-aluminium i-alloy ibandakanya ukukhuselwa kwe-welding, i-CMT yenguqu ebandayo ye-welding, i-tungsten inert gas (TIG) i-welding, i-riveting, i-punching, kunye nokugaya / ukupolisha.
3.1 I-Welding ngaphandle kwe-Riveting ye-Aluminium Sheets
Amacandelo e-aluminium ngaphandle kwe-riveting yenziwe ngokugqithiswa okubandayo kwamacandelo amabini okanye ngaphezulu kwamaphepha esinyithi usebenzisa izixhobo zoxinzelelo kunye nokubumba okukhethekileyo. Le nkqubo idala iindawo zoqhagamshelo ezizinzisiweyo kunye ne-tensile ethile kunye namandla okucheba. Ubunzima bamaphepha okudibanisa bungafana okanye bahluke, kwaye banokuba neengqimba zokubambelela okanye ezinye iileyile eziphakathi, kunye nezinto ezifanayo okanye ezahlukeneyo. Le ndlela ivelisa uxhulumaniso oluhle ngaphandle kwesidingo sokudibanisa abancedisayo.
3.2 I-Resistance Welding
Okwangoku, i-aluminiyam yokumelana ne-alloy welding ngokubanzi isebenzisa i-medium-frequency okanye i-high-frequency resistance resistance process. Le nkqubo yokuwelda inyibilikisa isiseko sesinyithi ngaphakathi kobubanzi be-electrode ye-welding ngexesha elifutshane kakhulu ukwenza i-weld pool,
iindawo zokuwelda zikhawuleza zipholile ukwenza unxibelelwano, kunye namathuba amancinci okuvelisa uthuli lwe-aluminium-magnesium. Uninzi lwemiphunga ye-welding eveliswayo iquka i-oxide particles ukusuka kwisinyithi kunye nokungcola komhlaba. I-ventilation yendawo yokukhupha umoya inikezelwa ngexesha lenkqubo ye-welding ukususa ngokukhawuleza la maqhekeza emoyeni, kwaye kukho ukuchithwa okuncinci kwe-aluminium-magnesium uthuli.
3.3 I-CMT ye-Cold Transition Welding kunye ne-TIG Welding
Ezi nkqubo zimbini ze-welding, ngenxa yokukhuselwa kwegesi ye-inert, ivelisa amancinci amancinci e-aluminium-magnesium kwiqondo lokushisa eliphezulu. Ezi ngqungquthela zinokutshiza kwindawo yokusebenza phantsi kwesenzo se-arc, zibeka umngcipheko wokuqhuma uthuli lwe-aluminium-magnesium. Ke ngoko, amanyathelo okhuseleko kunye namanyathelo okuthintela ukuqhuma kunye nonyango luyimfuneko.
IiMfuno ezi-4 zobuGcisa kwiAluminiyam yeSitampu saMashiti kwi-Edge Rolling
Umahluko phakathi kokuqengqeleka komphetho we-aluminiyam kunye nokuqengqeleka okuqhelekileyo kwephepha eliqengqelekayo elibandayo ubalulekile. I-aluminium ingaphantsi kwe-ductile kunentsimbi, ngoko ke uxinzelelo olugqithisileyo kufuneka lugwenywe ngexesha lokuqengqeleka, kwaye isantya sokuhamba kufuneka sihambe kancinci, ngokuqhelekileyo i-200-250 mm / s. I-angle nganye yokuqengqeleka ayifanele idlule i-30 °, kwaye i-V-shaped rolling kufuneka igwenywe.
Iimfuno zobushushu be-aluminium alloy rolling: Kufuneka iqhutywe kwi-20 ° C yobushushu begumbi. Amacandelo athathwe ngokuthe ngqo kwisitoreji esibandayo akufanele abekwe phantsi kwe-edge rolling ngokukhawuleza.

Ukuqengqeleka okuqhelekileyo kubandakanya amanyathelo amathathu: ukuqengqeleka kwangaphambili, ukuqengqeleka okwesibini, kunye nokuqengqeleka kokugqibela. Oku ngokuqhelekileyo kusetyenziswa xa kungekho mfuneko ezithile zamandla kwaye ii-angles ze-flange zeplate zangaphandle ziqhelekileyo.
Ukuqengqeleka kohlobo lwaseYurophu kunamanyathelo amane: ukuqengqeleka kwangaphambili, ukuqengqeleka okwesibini, ukuqengqeleka kokugqibela, kunye nokuqengqeleka kohlobo lwaseYurophu. Oku ngokuqhelekileyo kusetyenziselwa ukuqengqeleka okude, okufana namaqweqwe angaphambili nasemva. Ukuqengqeleka kohlobo lwaseYurophu kungasetyenziselwa ukunciphisa okanye ukuphelisa iziphene ezingaphezulu.
5.2 Iimpawu ze-Edge Rolling yee-Aluminium Stamping Sheets
Kwizixhobo zokuqengqeleka ze-aluminium, i-mold ephantsi kunye nebhloko yokufaka kufuneka iphuculwe kwaye igcinwe rhoqo nge-sandpaper ye-800-1200 # ukuqinisekisa ukuba akukho zilaphu ze-aluminium ezikhoyo phezu komhlaba.
6 Izizathu Ezahlukeneyo Zeziphene eziBangelwe kukuqengqeleka koMphetho weAluminiyam yeSitampu samaPhepha
Izizathu ezahlukeneyo zeziphene ezibangelwa ukuqengqeleka komphetho weengxenye ze-aluminium ziboniswe kwitheyibhile.
IiMfuno ezisi-7 zobuChwephesha zoKugquma amaPhepha eSitampu seAluminiyam
7.1 IMithetho-siseko kunye neZiphumo zoKuhlamba amanzi kwi-Aluminiyam yeSitampu saMaphepha
Ukuhlamba ukuhlamba ngamanzi kubhekiselele ekususeni ifilimu yeoksidi eyenziwe ngokwemvelo kunye namabala e-oyile kumphezulu wamalungu e-aluminiyam, kunye nokusabela kweekhemikhali phakathi kwealluminiyam kunye nesisombululo esineasidi, ukudala ifilimu eshinyeneyo ye-oxide kumphezulu womsebenzi. Ifilimu ye-oxide, amabala e-oyile, i-welding, kunye ne-adhesive bonding phezu kwendawo ye-aluminium emva kokunyathela zonke zinempembelelo. Ukuphucula ukubambelela kwi-adhesives kunye ne-welds, inkqubo yeekhemikhali isetyenziselwa ukugcina ukudibanisa okunamathelayo okuhlala ixesha elide kunye nokuzinza kokumelana phezu komhlaba, ukufezekisa i-welding engcono. Ke ngoko, iinxalenye ezifuna i-laser welding, i-cold metal transition welding (CMT), kunye nezinye iinkqubo ze-welding kufuneka zihlanjwe ngamanzi.
7.2 Inkqubo yokuHamba kwamanzi okuhlamba iPasivation yeAluminiyam yeeStampu zaMashiti
Isixhobo sokuhambisa amanzi sokuhlambela amanzi siquka indawo yokucoca, indawo yokuhlamba amanzi kwimizi-mveliso, indawo yokudlula, indawo yokuhlamba amanzi acocekileyo, indawo yokomisa, kunye nenkqubo yokukhupha. Iinxalenye ze-aluminium eziza kunyangwa zifakwe kwibhasikithi yokuhlamba, zilungiswe, kwaye zithotywe kwitanki. Kwiitanki eziqukethe i-solvents ezahlukeneyo, iinxalenye zihlanjululwa ngokuphindaphindiweyo kunye nazo zonke izisombululo zokusebenza kwi-tank. Onke amatanki axhotyiswe ngeempompo zokujikeleza kunye nemilomo yokuqinisekisa ukuhlanjululwa okufanayo kwazo zonke iindawo. Ukuhamba kwenkqubo yokuhlamba amanzi kuhamba ngolu hlobo lulandelayo: ukwehlisa igrisi 1→ukwehlisa igrisi 2→ukuhlamba amanzi 2→ukuhlamba amanzi 3→ukudlula →ukuhlamba amanzi 4→ukuhlamba amanzi 5→ukuhlamba amanzi 6→ukomisa. Iintsimbi ze-aluminiyam zinokutsiba ukuhlamba amanzi 2.
7.3 Inkqubo Yokomisa Ukuhlamba Amanzi Ukugqithiswa kweeStampu zeAluminiyam
Kuthatha malunga nemizuzu engama-7 ukuba iqondo lokushisa liphakame ukusuka kwiqondo lokushisa ukuya kwi-140 ° C, kwaye ixesha elincinci lokunyanga lokunamathiswa yimizuzu engama-20.
Amacandelo e-aluminium aphakanyisiwe ukusuka kwiqondo lokushisa ukuya kwiqondo lokushisa lokubamba malunga nemizuzu eyi-10, kwaye ixesha lokubamba i-aluminium malunga nemizuzu engama-20. Emva kokubamba, ipholile ukusuka kwiqondo lokushisa lokuzibamba ukuya kwi-100 ° C malunga nemizuzu eyi-7. Emva kokubamba, ipholiswa kwiqondo lokushisa. Ngoko ke, yonke inkqubo yokumisa kwiingxenye ze-aluminium yimizuzu engama-37.
8 Isiphelo
