Ke ka?ina hana extrusion alumini:
Ho?omaka ka extrusion maoli me ka ho?olei extrusion i ke ko?oko?o aluminika, pono e ho?omehana ?ia ke ko?oko?o ho?olei alumini ma mua o ka ho?one?e ?ia ?ana, ho?okomo ?ia ka ho?omehana alumini maika?i sheng ingot i loko o ka pahu extruder i loko, a laila ho?okele ?ia e ka ko?oko?o extrusion hydraulic ki?eki?e, ka ?O ka hopena mua o ka ko?oko?o extrusion he pad pressure, kahi ?āpana alumini palupalu i ho?omehana ?ia ma ka palaka ma lalo o ke kaomi ikaika mai ka punahelu miomio mōlina extrusion, e ki?i i ka huahana hope loa.
?O ka pā alumini ka hakahaka o ke ka?ina extrusion. ?O ka pā alumini no ka extrusion he pa?a a hollow paha ia, ma?a mau ka paukū?oloka?a, a ho?oholo ?ia kona lō?ihi e nā mea kāwili extrusion. Ho?olei pinepine ?ia nā kī?aha ?aumomona, hana ?ia a pehi ?ia kekahi. Hana ?ia ia e ke kani ?ana i nā kaola oka a me nā mea ho?ohui pono.Ho?onā ma?amau nā ko?oko?o i nā kekelē 450 ma kahi umu ho?omehana ma mua o ka ho?ouna ?ia ?ana e hana, me kahi o 10% i koe i nā ingot.
Ho?oka?ina 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 ?ekolu-dimensional deformation extrusion
3. Wahi a ke kūlana lubrication: ?a?ohe lubrication extrusion lubrication extrusion ideal lubrication extrusion
Nā maika?i o ka hana extrusion:
1. Ho?onui i ka hiki deformation o ka hao
Hiki i ka lakio extrusion o ke alumini ma?ema?e 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. Loa?a i nā huahana Extrusion nā kūlana ki?eki?e ki?eki?e
Hiki i ka deformation extrusion ke ho?omaika?i i ka microstructure a me nā pono mechanical o nā mea metala, ?oi aku no kekahi mau mea alumini me ka hopena extrusion, ke ?ano longitudinal (extrusion direction) o nā huahana mīkini extruded ma hope o ke kinai ?ana a me ka ?elemakule i?oi aku ke ki?eki?e ma mua o nā huahana like i hana ?ia e nā ?ano hana ?ē a?e. .
3. Loa?a ka laulā i nā huahana Extrusion
?A?ole hiki i ka hana Extrusion ke hana i ka paipu, ko?oko?o a me ka uea me ke ?ano paukū ma?alahi, akā hiki ke hana i nā ?āpana pa?a a hakahā me ke ?ano o ka ?āpana pa?akikī, a me nā ?āpana ?āpana ho?ololi me ka loli mālie a me ka loli mālie ma ke ?ao?ao lō?ihi o ka ?āpana huahana.
He ākea ho?i ka laulā o nā ana, mai nā paipu nui a me nā ?ikepili me nā ?āpana me ke anawaena o waho o 500-1000mm a i ka li?ili?i loa. extrusions kiko?ī me nā ?āpana ka nui o nā matchsticks.
