(6) Loaʻa iā ia ka ʻike loea kiʻekiʻe a paʻakikī loa ka hana ʻana, a loaʻa iā ia nā koi kūikawā no nā lako extrusion, nā mea hana, billets a me nā kaʻina hana.He laʻana ka Kiʻi 1 o ka ʻāpana o kekahi mau kikoʻī alumini alumini pololei.
2. Ka hoʻokaʻawale ʻana o nā mea hoʻoheheʻe alumini alumini kūikawā
Hoʻohana nui ʻia nā extrusions alumini alumini precision a ultra-precision i nā mea uila, nā mea kamaʻilio a me ka ʻepekema ʻokiʻoki, ka pale aupuni a me ka ʻoihana koa, nā mea hana mechanical precision, nā mea nāwaliwali o kēia manawa, aerospace, ʻoihana nuklea, ikehu a me ka mana, nā submarines a me nā moku, nā kaʻa a me nā mea halihali , nā mea lapaʻau, nā lako lako, nā kukui, nā kiʻi a me nā mea uila.Ma ka ʻōlelo maʻamau, hiki ke hoʻokaʻawale ʻia nā extrusions alumini alumini precision a i ʻole ultra-precision i ʻelua mau ʻāpana e like me ko lākou ʻano hiʻohiʻona: ʻo ka ʻāpana mua nā profiles me nā liʻiliʻi liʻiliʻi.Ua kapa ʻia kēia ʻano profile i ka ultra-small profile a i ʻole mini-shape.ʻO kona nui holoʻokoʻa maʻamau he mau millimeters wale nō, ʻo ka mānoanoa liʻiliʻi o ka pā ma lalo o 0.5mm, a ʻo ke kaumaha o ka ʻāpana he mau grams a ʻumi mau grams no ka mika.Ma muli o ko lākou liʻiliʻi liʻiliʻi, koi pinepine ʻia nā tolerances paʻa iā lākou.No ka laʻana, ʻoi aku ka liʻiliʻi o ka ʻae ʻana o nā ʻāpana cross-sectional ma mua o ± 0.05mm.Eia kekahi, koʻikoʻi loa nā koi no ka pololei a me ka torsion o nā huahana extruded.
ʻO nā ʻano ʻē aʻe, ʻaʻole liʻiliʻi loa i ka nui o ke keʻa akā koi ʻia nā ʻae ʻana o ka nui, a i ʻole nā palapala i loaʻa ke ʻano keʻa paʻakikī a me ka mānoanoa o ka paia lahilahi ʻoiai he nui ka nui o ke keʻa.Hōʻike ka Figure 2 i ka paipu ʻano kūikawā (ʻoihana alumini maʻemaʻe) i hoʻokuʻu ʻia e kahi hui Kepani ma kahi kaomi hydraulic horizontal 16.3MN me kahi make hoʻokaʻawale kūikawā no ka condenser air-condenser kaʻa.ʻAʻole i emi iki ka paʻakikī o ka extrusion o kēia ʻano ʻaoʻao ma mua o ke ʻano mua o ka ʻano ultra-liʻiliʻi.Extruded profiles me ka nui pauku nui a me ka koʻikoʻi koʻikoʻi hoʻomanawanui koi 'aʻole wale koi kiʻekiʻe kiʻekiʻe hoʻolālā hoʻolālā, akā, pono hoʻokō 'enehana hooponopono no ka holoʻokoʻa kaʻina hana mai blank a pau huahana.
Mai ka 1980s mua, ma muli o ka hoʻohana pono ʻana o ka ʻenehana conform extrusion mau a me ka hoʻomohala ʻana o ka ʻenehana ʻenehana, ua ulu wikiwiki ka extrusion o nā kiʻi liʻiliʻi a me nā ultra-liʻiliʻi.Eia nō naʻe, ma muli o nā kumu like ʻole e like me nā palena o nā mea hana, nā koi o ka huahana, a me nā holomua i ka ʻenehana extrusion, ʻo ka hana ʻana o nā kiʻi liʻiliʻi ma nā mea extrusion maʻamau e mau ana no ka hapa nui.Hōʻike ka Kiʻi 2 i nā kikoʻī kikoʻī o ka extrusion o nā make maʻamau.ʻO ke ola o ka mold (ʻoi aku ka ikaika a me ke kūpaʻa ʻana o ke alahaka shunt a me ka mold core) a me ke kahe waiwai i ka wā extrusion e lilo i kumu nui e pili ana i kāna hana.ʻO kēia no ka mea i ka wā e hoʻokuʻu ai i ka ʻaoʻao, liʻiliʻi ka nui o ka mold core a paʻakikī ke ʻano, a ʻo ka ikaika a me ke kūpaʻa ʻana he mau mea koʻikoʻi e pili ana i ke ola o ka mold, pili pono ke ola mold i ke kumukūʻai hana.Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka nui o nā ʻaoʻao kikoʻī i nā paia lahilahi a me nā ʻano paʻakikī, a ʻo ke kahe o nā mea i ka wā o ke kaʻina extrusion e pili pono i ke ʻano a me ka pololei o ka dimensional o nā profiles.
I mea e pale aku ai i ka oxide film a me ka aila ma luna o ka ili o ka billet mai ke kahe ʻana i loko o ka huahana a hōʻoia i ka ʻaʻahu a me ka hilinaʻi maikaʻi o ka huahana, hiki ke ʻili ʻia ka billet i hoʻomehana ʻia i ka mahana i hoʻonohonoho ʻia ma mua o ka extrusion (i kapa ʻia ka peeling wela), a a laila hoʻokomo koke i loko o ka pahu extrusion no ka extrusion.I ka manawa like, pono e hoʻomaʻemaʻe ʻia ka gasket extruded e pale i ka ʻaila a me ka lepo mai ka hoʻopili ʻana i ka gasket i ke kaʻina o ka wehe ʻana i ke kaomi nui ma hope o hoʻokahi extrusion a hoʻokomo i ka gasket i ka extrusion aʻe.
Wahi a ka ʻāpana kikoʻī a me ke ʻano a me ke kūpaʻa kūlana, hiki ke hoʻokaʻawale ʻia ka extrusion alumini alumini kūikawā kūikawā i nā profiles alumini alumini kūikawā kūikawā a me nā kiʻi liʻiliʻi (miniature) ultra-high precision alumini alumini.Ma keʻano laulā, ua ʻoi aku kona pololei ma mua o ke kūlana aupuni (e like me GB, JIS, ASTM, a me nā mea ʻē aʻe) ua kapa ʻia ka precision kiʻekiʻe kiʻekiʻe i nā profiles alumini alumini kūikawā, no ka laʻana, ʻoi aku ka nui o ka ʻae ʻana ma luna o ± 0.1mm, ka mānoanoa o ka pā. aia ka ʻili i haki i loko o ± 0.05mm ~ ± 0.03mm profiles a me nā paipu.
Ke ʻoi aku ka pololei o kona pololei ma mua o ka papalua o ke kūlana kiʻekiʻe kiʻekiʻe kiʻekiʻe o ka mokuʻāina, ua kapa ʻia ʻo ia he mea liʻiliʻi (miniature) ultra-high precision alumini alloy profile, e like me ke ʻano hoʻomanawanui o ± 0.09mm, ka mānoanoa o ka pā o ± 0.03mm ~ ± 0.01mm no kahi kiʻi liʻiliʻi (miniature) a i ʻole paipu.
