ʻO Aluminium extrusion shell, China bar extrusion mea hana, ʻo kā mākou ʻoihana kahi noiʻi maikaʻi loa a me ka hiki ke hoʻomohala a me ka hiki i ka hana, hoʻokipa iā ʻoe e hoʻopilikino i nā kikoʻī o ka pahu pahu aluminium, extrusion alumini extrusion ~
Ma ke ʻano he huahana uila kiʻekiʻe o ke kamepiula papa, he mea hoʻonaninani ikaika ka leho, ʻaʻole maikaʻi wale ka hana mechanical, a nani hoʻi nā hiʻohiʻona. No laila, ma hope o ka hana ʻana i ka mīkini a me ka mālama ʻana i ka iwi alumini, ʻaʻole i ʻae ʻia e loaʻa nā ʻeleʻele. , nā haumia, nā kiko, nā ʻalā a me nā hemahema ʻē aʻe i hiki i ka maka maka ʻole ke ʻike ʻia.
Ma muli o ka mīkini ʻana o ka mīkini CNC, ʻo ka nui o ka pono o ka pā alumini ma mua o ke kiʻekiʻe loa (ʻaʻole hiki ke hala i ka 250mm ākea ma mua o 0.05mm), no laila lawe mai nā pilikia nui i ka hana.
ʻO ka extrusion alumini o ka hihia papa
1) i mea e hana like ai ka huahana i ka hanana a me ka hana, e homogenized ka ingot. Hiki ke hoʻokō ʻia ke kaʻina hana homogenization e like me ke kinikini 6063 maʻamau.
2) ʻoiai ka huahana i ke ʻano o nā ʻano like ʻole a me ka nui, makemake ʻia e koho i ka umu hoʻowela wikiwiki, a ʻoi aku ka maikaʻi o ka gradient o ka mahana ingot.
Penei nā kumu:
ʻO ka mea mua, nui ka deformation o ke awa ingot i ʻoki ʻia e ka mīkini hoʻopaʻa wela lōʻihi i kēia manawa, kahi mea e hoʻopili ai i ka hopena peeling aʻe a maʻalahi e kahe i ka ʻili ingot i ka huahana extrusion.
ʻO ka lua, nui nā māwae i ka hoʻopaʻa, paʻakikī e hoʻopau pono i ka wā extrusion, e hoʻoulu i ka huewai huahana extrusion;
ʻO ke kolu, hoʻomehana wikiwiki ʻia ka ingot, kahi mea pono e mālama i ka mokuʻāina ma hope o ka homogenized ʻana o ka ingot; ʻEhā, hoʻomehana gradient o ka ingot (ʻo ka mahana ma ka mua o ka ingot ma kahi o 500 ℃, a ʻo ka mahana ma ka hopena ma kahi o 460 ℃), kahi mea e hōʻemi ai i ka hoʻoliʻiliʻi o ka huelo huʻihuʻi o ka huahana extrusion a me ke kūlike o nā meahana mechanical o ka huahana.
Mai ka noʻonoʻo ākea o ke kumukūʻai a me ke kaohi wela o ka ingot, manaʻo wau ʻoi aku ka maikaʻi o ka wela me ke kinoea kūlohelohe ma mua, a laila me ka umu hoʻokomo.
3) ʻili wela o ka ingot
I mea e pale aku ai i ka ʻili o ka ingot oxide ʻili a me nā sundries ʻē aʻe i loko o ka huahana extrusion, pono e hoʻomehana ʻia ka ingot i loko o ka paipu ingot i ka lāʻau "peeling", e like me ka hoʻolei ʻia ʻana o ka ʻili hoʻoheheʻe ʻia. kaukaʻi ʻia i ke anawaena a me ka nui o ka ingot, maʻamau 3 - 5mm.
4) lapaʻau kinai ʻana
ʻOiai ʻo ka huahana ma ka mokuʻāina o 6063T6, mānoanoa ka pā o ka paia a kiʻekiʻe nā koi ʻae mokulele. Inā hōʻoluʻolu ka lewa, haʻahaʻa loa ka wikiwiki anuanu, ʻaʻole maikaʻi ka hopena kinai, nui loa ka hua huapalaoa, ka haahaa nā waiwai mīkini. Inā pahu ka wai a ʻūpī paha ka huʻihuʻi, wikiwiki ka wikiwiki anuanu, a ʻaʻohe like ke anuanu, e hopena ana i ka hoʻololi ʻana o ka huahana koʻikoʻi, ka hoʻomaʻemaʻe mokulele ma waho o ka hoʻomanawanui. E hoʻonā i kēia pilikia, kahi hui o nā pono e hoʻohana ʻia nā anuanu.
Ma hope o ka hoʻāʻo, ʻo ka hoʻolālā ʻoi loa ka 4-5 mau mika me ka huʻihuʻi o ka noe e huʻihuʻi ana, ka mahana o ka huahana a hiki i nā kekelē 250, a laila 1-2 mika kahe. o kēlā me kēia kiko hoʻoluʻolu. Ma hope o ke kinai ʻana, hāʻule ka mahana o ka huahana ma kahi o 100 ℃. Inā hoʻohui i kahi ʻāpana o ke anuanu o ka lewa (ʻoi aku ka maikaʻi o 4 mika), ʻoi aku ka maikaʻi o ka hopena.
ʻAʻole hiki i kēia lapaʻau ke hoʻokō i nā koi o ka hōʻoluʻolu ikaika, hāʻawi i ka pāʻani piha i nā pono mechanical o ke kinikini, akā hoʻoliʻiliʻi hoʻi i ka hoʻololi o ka huahana, hōʻoia i nā koi o ka ʻae mokulele, a pale i ke ʻano o nā kaha wai, nā kiko ʻeleʻele a nā kīnā ʻē aʻe. He mea nui kēia akā nānā pinepine ʻole ʻia o ka hana.
ʻO ka extrusion alumini kahi ʻenehana ʻōnaehana, e loaʻa ka hopena o kēlā me kēia loulou i ka maikaʻi o ka huahana, pono kēlā me kēia loulou i ka lawa o ka nānā.
