1. Kumu o ka alumini extrusion

ʻO ka extrusion kahi ʻano hana extruding e hoʻokau i ka ikaika o waho i ka billet metala i loko o ka ipu (extrusion cylinder) a hoʻoheheʻe ʻia i waho o kahi lua make kikoʻī e loaʻa ai ke ʻano a me ka nui o ka ʻāpana i makemake ʻia.

2. ʻO ka māhele o ka alumini extruder

Hoʻokumu ʻia ka extruder me ke kiʻi, ke kolamu mua, ka kolamu hoʻonui, ka cylinder extrusion, ka ʻōnaehana hydraulic ma lalo o ka mana uila, a ua lako pū me ka mold base, thimble, scale plate, slide plate a pēlā aku.

3. ʻO ka hoʻokaʻawale ʻana o ke ala alumini extrusion

E like me ke ʻano o ka metala i loko o ka extrusion cylinder: Ke kuhikuhi o ke koʻikoʻi a me ka mokuʻāina, extrusion, lubricating state, extrusion temperature, extrusion speed, a i ʻole nā ​​ʻano o ka hale holomua, ke ʻano a me ka ʻole. o ka blank a i ole o ke ano o ka huahana, hiki ke maheleia i maikai extrusion, hope extrusion, (me ka plane strain extrusion, axisymmetric deformation extrusion, ekolu-dimensional deformation extrusion) lateral extrusion, aniani lubricating extrusion, Hydrostatic extrusion, hoomau extrusion a pela aku. ma.

4. Imua thermal deformation o alumini extrusion

ʻO ka hapa nui o nā ʻoihana hana alumini deformation wela e hoʻohana i ke ʻano extrusion deformation wela i mua ma o kahi make kūikawā (palapala make, cone die, shunt die) e kiʻi i nā profile alumini kūlike me ka ʻāpana a me ke ʻano.

He maʻalahi ke kaʻina hana extrusion mua, ʻaʻole kiʻekiʻe nā pono o nā mea hana, kiʻekiʻe ka hiki ke hoʻololi i ka metala, ākea ka laulā hana, hiki ke hoʻokele ʻia ka hana alumini, nui ka maʻalahi o ka hana, a maʻalahi ka mālama ʻana a hoʻoponopono hou.

ʻO ka hemahema me ka friction o ka ʻili mai ka pahu extrusion alumini i loko, kiʻekiʻe ka hoʻohana ʻana i ka ikehu, ʻoi aku ka maʻalahi o ka cylinder friction e hana i ka wela, a hoʻonui i ka instability profile, hoʻemi i ka pono o ka hoʻopau ʻana i ka huahana, kaupalena i ka alumini a me ka alumini alloy extrusion wikiwiki, wikiwiki. lole a me ka lawelawe ola o ka extrusion make, uneven huahana.

5. ʻO keʻano o ka hoʻoheheʻe wela alumini alumini, hana a hoʻohana

Hoʻokaʻawale ʻia nā ʻano o ka alloy alumini deformation wela i 8 mau ʻāpana e like me ka hana a me nā noi, ʻokoʻa kā lākou hana a me ka hoʻohana ʻana:

1) ʻO ka alumini maʻemaʻe (L series) e pili ana i ka pahu honua 1000 series alumini maʻemaʻe.

ʻO ka alumini maʻemaʻe ʻoihana, ka machinability maikaʻi loa, ka pale ʻana i ka corrosion, me ka mālama ʻana i ka ʻili a me ka conductivity uila, akā ikaika haʻahaʻa, hoʻohana ʻia i nā waiwai o ka hale, nā huahana uila, nā lāʻau lapaʻau a me nā meaʻai meaʻai, ka lawe ʻana a me ka hāʻawi ʻana i nā mea, etc.

2) Duralumin (Ly) pili i ka brand international 2000 Al-Cu (Aluminum-copper) alloy.

Hoʻohana ʻia i nā ʻāpana nui, kākoʻo, kiʻekiʻe Cu maʻiʻo, maikaʻi ʻole ka corrosion.

3) ʻO ka alumini paʻa-rust (LF) e pili ana i ka brand international 3000 Al-Mn (aluminum manganese) alloy.

ʻAʻole i hoʻoikaika ʻia ka mālama ʻana i ka wela, ka machinability, corrosion resistance a me ka alumini maʻemaʻe, ua hoʻomaikaʻi ʻia ka ikaika, ka hana kuʻi maikaʻi, hoʻohana nui ʻia i nā mea e pono ai i kēlā me kēia lā, nā mea kūkulu hale, nā mea hana a me nā mea ʻē aʻe.

4) Aluminum Kūikawā (LT) e pili ana i ka brand international 4000 Al-Si alloy.

ʻO ka mea nui wili, wahi hoʻoheheʻe haʻahaʻa (575-630 degere), ka wai maikaʻi.

5) Anti-rust alumini (LF) e pili ana i ka brand international 5000Al-Mg (aluminika a me ka magnesium).

ʻAʻole i hoʻoikaika ʻia ka mālama ʻana i ka wela, ka pale ʻana i ka corrosion, weldability, maikaʻi o ka ʻili o ka ʻili, ma o ka mana o ka ʻike Mg, hiki ke loaʻa i nā pae ikaika like ʻole. Haʻahaʻa haʻahaʻa no nā mea hoʻonani, nā mea hana kiʻekiʻe; ʻO ka pae waena no nā moku, nā kaʻa, nā mea kūkulu hale; Hoʻohana ʻia ka pae kiʻekiʻe no ka hoʻopili ʻana i nā ʻāpana i nā mea kanu kemika o nā moku a me nā kaʻa.

6) 6000Al-Mg-Si huila.

Hiki i ka Mg2Si ua hoʻopaʻapaʻa i ka wela ke hoʻoikaika i ka huila, ke kūpaʻa corrosion maikaʻi, ka ikaika haʻahaʻa, ka hana wela maikaʻi loa, no laila ua hoʻohana nui ʻia e like me ka extrusion material, formability maikaʻi, hiki ke loaʻa ka paʻakikī kiʻekiʻe ma ke kinai ʻana. Hoʻohana nui ʻia ia i ke kūkulu ʻana i nā profiles a ʻo ia ke kumu waiwai nui i ka ʻoihana.

7) ʻO ka alumini superhard (LC) e pili ana i ka brand international 7000Al-Zn-Mg-Cu (Al-Zn-Mg-Cu) kiʻekiʻe kiʻekiʻe alumini alumini a me Al-Zn-Mg alloy i hoʻohana ʻia no nā ʻāpana wili, nona ka ikaika kiʻekiʻe, maikaʻi loa kuʻihao a me quenching hana, akā, pōʻino koʻikoʻi corrosion & māwae kū'ē, i pono e hoʻomaikaʻi e ka wela wela kūpono. Hoʻohana nui ʻia ka mea mua no nā mokulele a me nā mea haʻuki, aʻo ka mea hope e hoʻohana nui ʻia no ka hoʻopaʻa ʻana i nā mea hana o nā kaʻa kaʻa.

8) 8000 (Al-Li) Aluminum-lithium alloy.

ʻO ka hiʻohiʻona nui loa ʻo ia ka 8% -9% haʻahaʻa ma mua o 7000-series, rigidity kiʻekiʻe, ikaika kiʻekiʻe, paona māmā, ke kūkulu ʻia nei kēia moʻo (ʻaʻole i lanakila piha ka mana anti-decay o ka metala alumini alumini ma lalo o nā kūlana paʻakikī. ), hoʻohana nui ʻia i nā mokulele, nā missiles, nā ʻenekini a me nā noi koa ʻē aʻe.
