1. Fa'avae ole alumini alumini
O le Extrusion o se auala faʻapipiʻiina e faʻapipiʻiina ai le malosi i fafo i luga o le uʻamea uʻamea i totonu o le atigipusa (extrusion cylinder) ma faʻafefe ai mai se pu faʻapitoa e maua ai le foliga ma le lapoa o le vaega.
2. Le vaega ole alumini extruder
O le extruder e aofia ai le faʻavaa, faʻavaa koluma pito i luma, koluma faʻalautele, faʻauʻu faʻapipiʻi, faʻaogaina o le eletise i lalo o le eletise, ma faʻapipiʻiina foʻi ma le faʻavae mold, thimble, scale plate, slide plate ma isi.
3. Le faʻavasegaina o auala alumini extrusion
E tusa ai ma le ituaiga uʻamea i totonu o le extrusion cylinder: Direction of stress and strain state, extrusion, lubricating state, extrusion temperature, extrusion saosaoa, poʻo le ituaiga o fausaga maualuga, foliga ma leai.o avanoa po o le ituaiga oloa, e mafai ona vaevaeina i extrusion lelei, extrusion tua, (e aofia ai le extrusion galugalu vaalele, axisymmetric deformation extrusion, lautele tolu-dimensional deformation extrusion) extrusion lateral, extrusion lubricating tioata, Extrusion Hydrostatic, extrusion faaauau pea ma faapena. luga.
4. Deformation vevela i luma o alumini extrusion
O le tele o pisinisi gaosi alumini vevela vevela e faʻaaogaina le auala e faʻafefe ai le vevela vevela e ala i se paʻu faʻapitoa (faʻapalapala, mate cone, shunt mate) e maua ai faʻamatalaga alumini tutusa ma le vaega ma foliga manaʻomia.
O le faʻagasologa o le faʻauluina i luma e faigofie, o mea e manaʻomia e le maualuga, o le faʻaogaina o le uʻamea e maualuga, o le gaosiga o le lautele e lautele, o le alumini alumini e mafai ona faʻatonutonuina, o le gaosiga o fetuutuunaiga e tele, ma e faigofie ona tausia ma toe faʻaleleia le limu.
O le faaletonu o loʻo i ai le feteʻenaʻiga mai le pito i totonu o le alumini extrusion tube, o le malosi o le faʻaaogaina e maualuga, o le paʻu faʻafefete e faigofie ona faʻafefe ai le vevela, ma faʻateleina faʻamatalaga faʻaletonu, faʻaitiitia le lelei o le faʻamaeʻaina o oloa, faʻatapulaʻa le alumini ma alumini alumini alumini saoasaoa, faʻavave. ofu ma auaunaga ola o le extrusion mate, oloa le tutusa.
5. Le ituaiga o vevela vevela alumini alumini, faʻatinoga ma faʻaoga
O ituaiga o vevela vevela alumini alumini ua vaevaeina i 8 vaega e tusa ai ma le faʻatinoga ma faʻaoga, o latou faʻatinoga ma faʻaoga e eseese:
1) Aluminium mama (L series) e fetaui ma le faʻasalalauga faʻavaomalo 1000 faʻasologa alumini mama.
Aluminum mama alamanuia, machinability sili ona lelei, corrosion teteʻe, faʻatasi ai ma togafitiga luga ma conductivity eletise, ae maualalo le malosi, faʻaaogaina i oloa fale, oloa eletise, vailaʻau ma meaʻai afifi, felauaiga ma tufatufaina mea, ma isi.
2) Duralumin (Ly) e fetaui ma le faʻailoga faavaomalo 2000 Al-Cu (Aluminium-kopa) uʻamea.
Faʻaaogaina i vaega tetele, lagolago, maualuga Cu i totonu, leaga le faʻafefe.
3) Alumini ele-fa'amaonia (LF) e fetaui ma le fa'ailoga fa'ava-o-malo 3000 Al-Mn (aluminium manganese).
O togafitiga vevela e le faʻamalosia, machinability, corrosion resistance ma alumini mama, malosi ua faʻaleleia, lelei le faʻaogaina, faʻaaogaina lautele i mea e manaʻomia i aso uma, mea faufale, masini ma isi vaega.
4) Faʻapitoa Alumini (LT) e fetaui ma le faʻailoga faavaomalo 4000 Al-Si alloy.
Fa'atosina mea uelo, maualalo mea liusuavai (575-630 tikeri), lelei fluidity.
5) Anti-rust alumini (LF) e fetaui ma le faʻailoga faavaomalo 5000Al-Mg (alumini ma le magnesium) uʻamea.
O togafitiga vevela e le faʻamalosia, teteʻe o le corrosion, weldability, sili ona lelei le susulu, e ala i le puleaina o le Mg content, e mafai ona maua ni tulaga malosi eseese o le uʻamea.Tulaga maualalo mo mea teuteu, masini faʻapitoa;Tulaga maualuga mo va'a, ta'avale, mea faufale;Tulaga maualuga o lo'o fa'aaogaina mo vaega uelo i fale kemisi o va'a ma ta'avale.
6) 6000Al-Mg-Si uamea.
Mg2Si precipitation faʻamaʻaina togafitiga vevela e mafai ona faʻamalosia ai le uʻamea, lelei le faʻafefeteina, malosi faʻalelei, sili atu le faʻaogaina o le vevela, o lea e faʻaaogaina lautele e pei o mea faʻapipiʻi, foliga lelei, maaa maualuga e mafai ona maua e ala i le tineia.E fa'aaogaina lautele i le fausiaina o tala'aga ma o le autu autu o meafaitino i alamanuia.
7) Superhard alumini (LC) e fetaui ma le faʻailoga faavaomalo 7000Al-Zn-Mg-Cu (Al-Zn-Mg-Cu) alumini alumini malosi ma Al-Zn-Mg faʻaogaina mo vaega uʻamea, lea e maualuga le malosi, fa'alelei lelei ma tineia fa'atinoga, ae le lelei le fa'alavelave fa'afefe & ta'eta'e tete'e, lea e mana'omia ona fa'aleleia e ala i togafitiga vevela talafeagai.O le mea muamua e masani ona faʻaaogaina mo vaalele ma mea tau taaloga, ae o le mea mulimuli e masani ona faʻaaogaina mo le faʻaogaina o mea faʻavae o taavale afi.
8) 8000 (Al-Li) Alumini-lithium alloy.
O le uiga sili ona tele o le mamafa o le 8% -9% maualalo ifo nai lo le 7000-series, maualuga maualuga, malosi maualuga, mamafa mama, o lenei faʻasologa o loʻo i lalo o le atinaʻeina (o le malosi e tetee atu i le pala o le uʻamea alumini alumini i lalo o tulaga faigata e leʻi faʻatoʻilaloina atoa. ), e masani ona faʻaaogaina i vaalele, missiles, afi ma isi talosaga a le militeri.
