ʻO nā hiʻohiʻona nui o ka alumini alumini kūikawā kūikawā (a i ʻole ultra-precision) extrusions:
(1) Nui nā ʻano like ʻole, nā pūʻulu liʻiliʻi, a ʻo ka hapa nui o lākou he mau mea extrusion kumu kūikawā, i hoʻohana ʻia ma nā wahi āpau o ke ola a me nā ʻano āpau o ke ola o nā kānaka, me nā huahana extrusion āpau, e like me nā paipu, nā kaola, nā profiles. a me nā uea, e pili ana i nā huila like ʻole a me ka mokuʻāina. Ma muli o kona ʻāpana keʻa liʻiliʻi, ka mānoanoa o ka paia lahilahi, ke kaumaha māmā, a me nā pūʻulu liʻiliʻi, ʻaʻole maʻalahi ka hoʻonohonoho ʻana i ka hana.
(2) Nā hiʻohiʻona paʻakikī a me nā hiʻohiʻona kūikawā, ka hapa nui o ke ʻano, pālahalaha, ākea, ʻēheu, niho, porous profile a paipu paha. Nui ka ʻili o kēlā me kēia ʻāpana, a paʻakikī ka ʻenehana hana.
(3) Ke noi ākea, ka hana kūikawā a me nā koi hana. No ka hoʻokō ʻana i nā koi hoʻohana o ka huahana, koho ʻia nā mokuʻāina he nui, e uhi ana i nā mea āpau āpau mai 1 × × × a hiki i ka 8 × × × moʻo a me nā hanana o ka mālama ʻana, me ka ʻike loea kiʻekiʻe.
(4) ʻO ka hiʻohiʻona nani a me ka mānoanoa o ka paia lahilahi, ʻoi aku ka liʻiliʻi ma mua o 0.5mm, hiki i kekahi ma kahi o 0.1mm, ʻo ke kaumaha o ka mika he liʻiliʻi wale nō i ka ʻumi o ka grams, akā hiki i ka lōʻihi ke hiki i kekahi mau mika, a i ʻole haneli mau mika. .
5) He koʻikoʻi loa ka pono o ka dimensional a me ka geometric tolerance koi o ka ʻāpana. ʻO ka ʻōlelo maʻamau, ʻoi aku ka paʻakikī o ka hoʻomanawanui ʻana o nā kiʻi kikoʻī alumini alumini liʻiliʻi ma mua o ʻelua ʻoi aku ka paʻakikī e like me nā ʻae kūikawā ma JIS, GB, a me nā kūlana ASTM. Pono ka mānoanoa o ka pā o nā profiles alumini alumini maʻamau ma waena o ± 0.04mm a me 0.07mm, aʻo ka nui o ka ʻae ʻana o ka ʻāpana alumini alumini alumini kiʻekiʻe e like me ± 0.01mm. No ka laʻana, ʻo ke kaumaha o ka profile alumini pololei i hoʻohana ʻia no ka potentiometer he 30g/m, a ʻo ka laulā hoʻomanawanui o ka nui o ka pauku he ± 0.07mm. ʻO ka hoʻomanawanui ʻana o ka nui o nā ʻāpana alumini pololei no nā mea looms he ± 0.04mm, ʻoi aku ka liʻiliʻi o ka ʻae ʻana ma mua o 0.5 °, a ʻo ka degere bending he 0.83 × L. ʻO kekahi laʻana, ʻo ia ka paipu pālahalaha ultra-thin kiʻekiʻe no nā kaʻa, me ka laulā o 20mm, ke kiʻekiʻe o 1.7mm, ka mānoanoa o ka pā o 0.17±0.01mm, a me 24 mau puka, ʻo ia ka mea maʻamau o nā kiʻi alumini alumini maʻamau.
(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 hoʻoheheʻe kūikawā (industrial pure aluminika) 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 lako, 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, nui nā ʻaoʻao kikoʻī i loaʻa 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 profile.
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 ka wā o 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.
