Ke kaʻina hana extrusion alumini:
Hoʻomaka ka extrusion maoli me ka hoʻolei extrusion i ke koʻokoʻo aluminika, pono e hoʻomehana ʻia ke koʻokoʻo hoʻolei alumini ma mua o ka hoʻoneʻe ʻia ʻana, hoʻokomo ʻia ka hoʻomehana alumini maikaʻi sheng ingot i loko o ka pahu extruder i loko, a laila hoʻokele ʻia e ka koʻokoʻo extrusion hydraulic kiʻekiʻe, ka ʻO ka hopena mua o ka koʻokoʻo extrusion he pad pressure, kahi ʻāpana alumini palupalu i hoʻomehana ʻia ma ka palaka ma lalo o ke kaomi ikaika mai ka punahelu miomio mōlina extrusion, e kiʻi i ka huahana hope loa.
ʻO ka pā alumini ka hakahaka o ke kaʻina extrusion. ʻO ka pā alumini no ka extrusion he paʻa a hollow paha ia, maʻa mau ka paukūʻolokaʻa, a hoʻoholo ʻia kona lōʻihi e nā mea kāwili extrusion. Hoʻolei pinepine ʻia nā kīʻaha ʻaumomona, hana ʻia a pehi ʻia kekahi. Hana ʻia ia e ke kani ʻana i nā kaola oka a me nā mea hoʻohui pono.Hoʻonā maʻamau nā koʻokoʻo i nā kekelē 450 ma kahi umu hoʻomehana ma mua o ka hoʻouna ʻia ʻana e hana, me kahi o 10% i koe i nā ingot.
Hoʻokaʻina o nā hana extrusion:
1. Wahi a ke kuhikuhi extrusion: extrusion mua, extrusion hope, extrusion lateral
2. E like me ka deformation ano: mokulele deformation extrusion axial symmetry deformation extrusion laulaha ʻekolu-dimensional deformation extrusion
3. Wahi a ke kūlana lubrication: ʻaʻohe lubrication extrusion lubrication extrusion ideal lubrication extrusion
Nā maikaʻi o ka hana extrusion:
1. Hoʻonui i ka hiki deformation o ka hao
Hiki i ka lakio extrusion o ke alumini maʻemaʻe ke hiki i 500, hiki i ka lakio extrusion o ke keleawe keleawe 400, a me ka lakio extrusion o ke kila hiki i 40-50.
2. Loaʻa i nā huahana Extrusion nā kūlana kiʻekiʻe kiʻekiʻe
Hiki i ka deformation extrusion ke hoʻomaikaʻi i ka microstructure a me nā pono mechanical o nā mea metala, ʻoi aku no kekahi mau mea alumini me ka hopena extrusion, ke ʻano longitudinal (extrusion direction) o nā huahana mīkini extruded ma hope o ke kinai ʻana a me ka ʻelemakule iʻoi aku ke kiʻekiʻe ma mua o nā huahana like i hana ʻia e nā ʻano hana ʻē aʻe. .
3. Loaʻa ka laulā i nā huahana Extrusion
ʻAʻole hiki i ka hana Extrusion ke hana i ka paipu, koʻokoʻo a me ka uea me ke ʻano paukū maʻalahi, akā hiki ke hana i nā ʻāpana paʻa a hakahā me ke ʻano o ka ʻāpana paʻakikī, a me nā ʻāpana ʻāpana hoʻololi me ka loli mālie a me ka loli mālie ma ke ʻaoʻao lōʻihi o ka ʻāpana huahana.
He ākea hoʻi ka laulā o nā ana, mai nā paipu nui a me nā ʻikepili me nā ʻāpana me ke anawaena o waho o 500-1000mm a i ka liʻiliʻi loa. extrusions kikoʻī me nā ʻāpana ka nui o nā matchsticks.
