1. Mfundo ya aluminiyamu extrusion

Extrusion ndi extruding processing njira kuti amaika mphamvu kunja pa zitsulo billet mu chidebe (extrusion yamphamvu) ndi kupanga izo kutuluka mu dzenje enieni kufa kupeza kufunika gawo mawonekedwe ndi kukula.

2. Chigawo cha aluminiyamu extruder

The extruder wapangidwa chimango, kutsogolo ndime chimango, ndime kutambasuka, yamphamvu extrusion, dongosolo hayidiroliki pansi ulamuliro magetsi, komanso okonzeka ndi nkhungu m'munsi, thimble, mbale masikelo, slide mbale ndi zina zotero.

3. Gulu la aluminiyamu extrusion njira

Malinga ndi mtundu wa zitsulo mu yamphamvu extrusion: Direction wa nkhawa ndi kupsyinjika boma, extrusion, lubricating boma, extrusion kutentha, extrusion liwiro, kapena mitundu ya mapangidwe apamwamba, mawonekedwe ndi ayi. opanda kanthu kapena amtundu wa mankhwala, akhoza kugawidwa mu extrusion zabwino, mmbuyo extrusion, (kuphatikizapo kupsyinjika kwa ndege, axisymmetric mapindikidwe extrusion, ambiri azithunzithunzi atatu mapindikidwe extrusion) ofananira nawo, galasi lubricating extrusion, Hydrostatic extrusion, extrusion mosalekeza ndi zina zotero.

4. Patsogolo matenthedwe mapindikidwe a aluminiyamu extrusion

Mabizinesi ambiri otentha a aluminiyumu opanga ma aluminium amatengera njira yowotchera yowotcha yakutsogolo kudzera pakufa kwina (kufa kosalala, kufa kwa cone, kufa kwa shunt) kuti apeze mbiri yofananira ya aluminiyamu yokhala ndi gawo ndi mawonekedwe omwe mukufuna.

Njira yakutsogolo ya extrusion ndiyosavuta, zida zomwe zimafunikira sizokwera kwambiri, kuthekera kwachitsulo kumapindika ndikwambiri, mitundu yopangira ndi yotakata, magwiridwe antchito a aluminiyumu amatha kuwongolera, kusinthasintha kwa kupanga ndi kwakukulu, ndipo nkhungu ndiyosavuta kuyisunga ndikuwongolera.

Chilema ndi pamwamba kukangana kuchokera mkati zotayidwa extrusion chubu, mowa mphamvu ndi mkulu, mikangano yamphamvu n'zosavuta kuti kuponyera kutentha, ndi kuonjezera mbiri Kusakhazikika, kuchepetsa dzuwa la kutsirizitsa mankhwala, kuchepetsa zotayidwa ndi zotayidwa aloyi extrusion liwiro, inapita patsogolo kuvala ndi moyo utumiki wa extrusion kufa, mankhwala osagwirizana.

5. Mtundu wa otentha deformation aluminiyamu aloyi, ntchito ndi ntchito

Mitundu ya aloyi yotentha ya aluminiyamu imagawidwa m'magulu 8 malinga ndi magwiridwe antchito ndi magwiridwe antchito, magwiridwe antchito ndi ntchito zawo ndizosiyana:

1) zotayidwa koyera (L mndandanda) lolingana ndi mtundu mayiko 1000 mndandanda koyera zotayidwa.

Industrial zotayidwa koyera, machinability kwambiri, kukana dzimbiri, ndi mankhwala pamwamba ndi madutsidwe magetsi, koma mphamvu otsika, ntchito katundu wapakhomo, mankhwala magetsi, mankhwala ndi ma CD chakudya, kufala ndi kugawa zipangizo, etc.

2) Duralumin (Ly) imagwirizana ndi mtundu wa mayiko 2000 Al-Cu (Aluminium-copper) alloy.

Amagwiritsidwa ntchito pazigawo zazikulu, zothandizira, kuchuluka kwa Cu, kukana kwa dzimbiri.

3) Aluminiyamu yotsutsa dzimbiri (LF) yofanana ndi mtundu wapadziko lonse lapansi wa 3000 Al-Mn (aluminium manganese) aloyi.

Kuchiza kutentha sikulimbitsidwa, machinability, kukana dzimbiri ndi aluminiyamu yoyera, mphamvu zakhala zikuyenda bwino, ntchito yabwino yowotcherera, yomwe imagwiritsidwa ntchito kwambiri pazinthu zatsiku ndi tsiku, zomangira, zida ndi zina.

4) Aluminiyamu Wapadera (LT) yogwirizana ndi mtundu wapadziko lonse wa 4000 Al-Si alloy.

Makamaka kuwotcherera zinthu, otsika kusungunuka mfundo (575-630 madigiri), fluidity wabwino.

5) Anti-dzimbiri aluminiyamu (LF) yogwirizana ndi mtundu wapadziko lonse lapansi 5000Al-Mg (aluminium ndi magnesium) aloyi.

Chithandizo cha kutentha sichimalimbikitsidwa, kukana kwa dzimbiri, kutsekemera, kutsekemera bwino kwambiri, kupyolera mu mphamvu ya Mg, ikhoza kupeza mphamvu zosiyanasiyana za aloyi. Mlingo wotsika wa zipangizo zokongoletsera, zipangizo zamakono; Mulingo wapakatikati wa zombo, magalimoto, zida zomangira; High mlingo ntchito kuwotcherera zigawo mu mankhwala zomera zombo ndi magalimoto.

6) 6000Al-Mg-Si aloyi.

Mg2Si mpweya kuumitsa kutentha mankhwala akhoza kulimbikitsa aloyi, zabwino dzimbiri kukana, zolimbitsa mphamvu, kwambiri matenthedwe workability, choncho chimagwiritsidwa ntchito monga extrusion zakuthupi, formability wabwino, kuuma mkulu akhoza analandira ndi quenching. Amagwiritsidwa ntchito kwambiri pomanga mbiri ndipo ndiye gwero lalikulu pamakampani.

7) Superhard aluminiyamu (LC) limafanana ndi mtundu mayiko 7000Al-Zn-Mg-Cu (Al-Zn-Mg-Cu) mkulu-mphamvu zotayidwa aloyi ndi Al-Zn-Mg aloyi ntchito kuwotcherera zigawo zikuluzikulu, amene ali ndi mphamvu mkulu, kuwotcherera kwambiri ndi kuzimitsa ntchito, koma osauka nkhawa dzimbiri ndi kulimbana ndi kutentha kwa dzimbiri ndi kukana kutentha. Zoyambazo zimagwiritsidwa ntchito kwambiri pa ndege ndi katundu wamasewera, pomwe zomalizazi zimagwiritsidwa ntchito kwambiri pakuwotcherera zida zamagalimoto anjanji.

8) 8000 (Al-Li) Aluminiyamu-lithiyamu aloyi.

chachikulu khalidwe ndi kachulukidwe ndi 8% -9% m'munsi kuposa 7000-mndandanda, kuuma mkulu, mphamvu mkulu, kuwala kulemera, mndandanda ndi chitukuko (kukhoza odana ndi kuwola aloyi zitsulo zotayidwa pansi pa zinthu zovuta sanagonjetsedwe), makamaka ntchito ndege, zoponya, injini ndi ntchito zina zankhondo.
