ʻO nā ʻano hana hana superplastic no nā lau titanium alloy

ʻO nā ʻano hana hana superplastic no nā ʻāpana huila titanium hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻano:

(1) Hoʻomāmā;

(2) Pneumatic forming (puʻi hoʻoheheʻe);

(3) molding (coupled molding).

Hoʻohana mau ʻia nā ala mua ʻelua no ka hana ʻana i nā huahana plastic (a i ʻole aniani). Hiki ke hoʻohana ʻia ka hana hoʻoheheʻe ʻana o Titanium sheet superplastic no ka mea he deformation kahe ʻana a i ʻole semi-viscous. Hiki ke hoʻohana pū ʻia ka hana pneumatic me ka hana ʻana i ka vacuum.

1. Titanium alloy plate vacuum hana ʻano hana

Hiki ke hoʻokaʻawale ʻia ke ʻano hana ʻana i ʻelua ʻano: ke ʻano make convex a me ke ʻano make concave.

ʻO ke ʻano o ka convex die he ala hana ia e hoʻopili ʻia ai ka huluhulu wela ma ka convex die me ke ʻano o loko o ka ʻāpana, i hoʻohana ʻia e hana i nā ʻāpana me ka pololei o loko. ʻO ke ʻano concave die kahi ʻano hana e hoʻopili ʻia ai ka mea wela ma luna o kahi make concave me ke ʻano o ka ʻāpana, a hoʻohana ʻia e hana i nā ʻāpana e koi ana i ka pololei kiʻekiʻe. Ma ka ʻōlelo maʻamau, hoʻohana ʻia ka mea mua no ka hana ʻana i nā ipu hohonu, a hoʻohana ʻia ka hope no ka hana ʻana i nā ipu pāpaʻu.

ʻO ka hoʻoheheʻe ʻia ʻana he ʻano hoʻi o ke ea e hoʻokumu ʻia, akā hiki ke hoʻokumu ʻia i loko o ka lewa hoʻokahi wale nō. No laila, hiki i ka pā titanium ke hana i ka mānoanoa lahilahi, ke ʻano maʻalahi, ka curvature, a me nā ʻāpana lohi, ʻaʻole kūpono no ka hana ʻana i nā ʻano mānoanoa, ʻoi aku ka paʻakikī a me ka deformation nui o nā ʻāpana.

2. ʻO ke ʻano hana pneumatic titanium alloy sheet (ke ʻano puhi puhi)

He ʻano hana hoʻonui kūikawā kēia.

Loaʻa ke kaʻina hana hoʻonui kuʻuna e ka mechanical, hydraulic expansion, a i ʻole nā ​​​​hana hoʻonui pahū, ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ke kaomi a me ka ikehu, a ma muli o nā palena o ka plasticity material, ʻaʻole nui loa ka deformation. ʻO ka hoʻoheheʻe ʻana he ʻano hana me ka haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa hiki ke loaʻa i ka deformation nui, ʻo ia ke ʻano o ka ʻenehana hana pepa ʻokoʻa mai ka manaʻo kaʻina hana kuʻuna. No ka mea, ua noa ka metala i ke kaʻina hana deformation, aneane pau ka mana i ka hana deformation a he liʻiliʻi loa ka poho friction (no ka hoʻoheheʻe manuahi, ʻaʻohe poho friction), he ʻokoʻa loa ia mai nā stamping a me ka hana ʻana.

Hiki ke hoʻokaʻawale ʻia ka hoʻoheheʻe ʻana i ʻelua mau ʻāpana: ka hoʻoheheʻe manuahi a me ka hoʻoheheʻe ʻana. Hoʻohālikelike ʻia ka mold blow molding e ka hapalua make, e like me ka hoʻoheheʻe ʻana, a ua māhele ʻia hoʻi i ʻelua ʻano convex molding a me concave molding; ʻO ka ʻokoʻa, ʻoi aku ka nui o ke kaomi hana ma mua o hoʻokahi lewa, akā hoʻoponopono pū i ke kaomi ma o ka ʻōnaehana kumu ea, a no laila hiki ke hana ʻia i nā ʻano paʻakikī, nā loli curvature i nā ʻāpana.

(1) ʻO ke ʻano hoʻoheheʻe manuahi manuahi

ʻO kēia ke ʻano maʻalahi loa o ke ʻano wei. Hōʻike ʻia ʻo ia e ka nele o kahi mold, a ʻo nā ʻāpana maʻamau i puhi ʻia he mau ʻāpana spherical.

(2) Keʻano hana make convex

ʻO kēia ʻano hana ka hana ʻana i ka ʻaoʻao o waho o ka huluhulu titanium plate, ka hoʻokumu ʻana i kahi wahi paʻa paʻa, ka pā titanium i hoʻomehana ʻia i ka mahana superplastic, ma lalo o ka hana o ke kaomi kinoea i hoʻopaʻa ʻia, ka huluhulu superplastic deformation, kokoke kokoke i ka lepo. a hiki i ka poni me ke kūpono piha, e hana i nā ʻāpana like a me ka ʻili. ʻO ka ʻaoʻao o loko o ka ʻāpana i hana ʻia he kiʻekiʻe ka kikoʻī a me ke ʻano pololei, a ʻo ka hoʻohālikelike ʻana o ka hohonu a me ka laulā he nui, a ʻoi aku ka maʻalahi o ka hana ʻana o ka ʻōpala, akā ʻoi aku ka paʻakikī o ka hoʻokuʻu ʻana i ka mold, a ʻo ka mea maka. ʻoi aku ka pipiʻi. ʻOi aku ka mānoanoa o ka ʻāpana i hana ʻia e kēia ʻano ma mua o ka puni.

(3) Keʻano hana make concave

ʻAʻole like me ka convex die-forming method, ua hoʻokumu ʻia kahi wahi paʻa paʻa i loko o ka waihona titanium plate i ka wā o ke kaʻina hana. ʻO ka ʻaoʻao o waho o ka ʻāpana i hana ʻia he kiʻekiʻe kiʻekiʻe a me ke ʻano pololei, a ʻoi aku ka maʻalahi o ka hoʻokuʻu ʻana mai ka ʻōpala a mālama i nā mea maka, akā liʻiliʻi ka hohonu a me ka laulā, a ʻoi aku ka paʻakikī o ka hana ʻana. ʻO ka lalo o nā ʻāpana i hana ʻia e kēia ʻano ʻoi aku ka lahilahi ma mua o ka puni.

3. ʻano hana hoʻoheheʻe ʻana o ka pā hao titanium

ʻO ka hoʻohana ʻana i kahi mold hui. ʻOkoʻa mai ka paʻi paʻi maʻamau ka wela kiʻekiʻe, ʻoi aku ka lohi o ka wikiwiki kaomi ʻana.
