Kaʻina hana huila alumini alumini

Hoʻokaʻawale ʻia ke kaʻina hana o nā huila kaʻa alumini alumini i nā ʻāpana aʻe:

1. Kaʻina hoʻolei:

• Ka umekaumaha: E ninini i ka wai alumini alumini i loko o ka mold, e hoʻopiha i ka poʻi ma lalo o ka'umekaumaha a hoʻolili i ke ʻano. ʻO kēia kaʻina hana he haʻahaʻa haʻahaʻa haʻahaʻa a me ka hana maʻalahi, kahi kūpono no ka hana liʻiliʻi. Eia nō naʻe, haʻahaʻa ka maikaʻi o ka hoʻolei ʻana, maikaʻi ʻole ka maikaʻi o ka huahana, a ʻoi aku ka maikaʻi o ka hoʻolei ʻana e like me nā pores a me ka shrinkage.

• Ka hoolei haahaa: I loko o ka pahu i hoailonaia, ua kaomiia ka wai alumini alumini i loko o ka poni ma ke kaomi haahaa ma o ke kinoea inert e paa ai ia malalo o ke kaomi. ʻO nā hoʻoheheʻe i hana ʻia e kēia kaʻina hana he ʻano paʻa, maikaʻi i loko, maikaʻi ka hana kiʻekiʻe, a kūpono no ka hana nui, akā nui ka hoʻopukapuka lako, kiʻekiʻe nā koi mold, a kiʻekiʻe hoʻi ke kumukūʻai mold.

• Hoʻolei milo: He hana i hoʻomaikaʻi ʻia ma muli o ka hoʻolei haʻahaʻa haʻahaʻa. ʻO ka mea mua, hana ʻia ka blank o ka huila e ka hoʻolei haʻahaʻa, a laila hoʻopaʻa ʻia ka blank ma ka mīkini wili. Hoʻololi mālie ʻia ke ʻano o ka ʻāpana rim a hoʻolōʻihi ʻia e ka wili a me ke kaomi. ʻAʻole mālama wale kēia kaʻina i nā pono o ka hoʻolei haʻahaʻa haʻahaʻa, akā hoʻomaikaʻi pū i ka ikaika a me ka pololei o ka huila, ʻoiai e hoʻemi ana i ke kaumaha o ka huila.

2. Kaʻina hana forging

Ma hope o ka hoʻomehana ʻia ʻana o ka alumini alumini i kahi mahana, hana ʻia ia i loko o kahi mol e kahi paʻi forging. Hiki ke hoʻokaʻawale ʻia nā kaʻina hana forging i ʻelua mau ʻano:

• Ka hana maʻamau: Hoʻopili pololei ʻia kahi ʻāpana alumini ingot i ke ʻano o ka huila ma lalo o ke kaomi kiʻekiʻe. ʻO ka huila i hana ʻia e kēia kaʻina hana he kiʻekiʻe ka hoʻohana ʻana i ka waiwai, ka liʻiliʻi o ka ʻōpala, nā waiwai mechanical maikaʻi o ka forgings, a me ka ikaika a me ka paʻakikī. Eia nō naʻe, nui ka hoʻopukapuka lako, paʻakikī ke kaʻina hana, a pono ke kiʻekiʻe o ka ʻenehana o ka mea hana.

• Semi-solid forging: ʻO ka mea mua, ua hoʻomehanaʻia ke alumini alumini i kahi kūlana semi-solid, i ia manawa i loaʻa i ka alumini alumini kekahi fluidity a me ka forgeability, a laila hanaʻia. Hiki i kēia kaʻina hana ke hōʻemi i ka hoʻohana ʻana i ka ikehu ma ke kaʻina hana forging, hoʻomaikaʻi i ka hana hana, a hoʻomaikaʻi pū i ka maikaʻi o ka huila.

3. Kaʻina hana welding

Hoʻopili ʻia ka pepa i loko o ka cylinder a welded, a hoʻomaʻamaʻa wale ʻia a paʻi ʻia paha i loko o ka rim huila me kahi ʻōpala, a laila welded ka disc huila pre-cast e hana i kahi huila. Hiki ke hoʻohana ʻia ke ʻano o ka welding i ka welding laser, electron beam welding, a me nā mea ʻē aʻe. Pono kēia kaʻina hana i kahi laina hoʻolaʻa hoʻolaʻa me ka hana kiʻekiʻe o ka hana ʻana a kūpono no ka hana nui, akā maikaʻi ʻole ka hiʻohiʻona a hiki i nā pilikia o ka maikaʻi o ka welding ke kū ma nā wahi welding.
