He aha nā huahana Metallurgy Powder?

Nā huahana metallurgy pauda ʻO nā ʻāpana sintered i hana ʻia e ka pauka metallurgy me ka pololei o ka dimensional a hiki ke kū i ka tensile, compression, distortion a me nā ukana ʻē aʻe a i ʻole hana ma lalo o ka friction a me nā kūlana ʻaʻahu, ʻike ʻia hoʻi nā ʻāpana sintered.

Nā ʻano: ʻO ka mea i hana ʻia a ma hopeʻāpana sinteredua kaomi ʻia i loko o kahi uniaxial rigid die ma ka lumi wela.

Noi: Hoʻohana nui ʻia nā ʻāpana metallurgy powder i ka ʻoihana kaʻa, a loaʻa nā noi ʻoi aku ka maikaʻi i ka wā e hiki mai ana.

ʻO nā mea maikaʻi o nā ʻāpana metallurgy pauka

• Ke ʻano like ʻole nā ​​ʻāpana, puka a lua paha, a me nā lua kūikawā like ʻole, maʻalahi ka hana ʻana i ka metallurgy pauka, a ʻaʻohe pono a i ʻole he wahi liʻiliʻi o ka ʻoki hoʻohui. Loaʻa iā ia ka hoʻokele waiwai.

• Ke hoʻohana nei i ke kaʻina hana metallurgy pauka e hana i nā ʻāpana mechanical, hiki ke piʻi ka nui o ka hoʻohana waiwai ma mua o 99.5%.

• No ka mea ua hana ʻia nā ʻāpana o ke kaʻina hana pauka me nā mold, ʻoi aku ka maikaʻi o ke ʻano o ka outline, ke ʻano a me ka nui o nā ʻāpana, a he nui nā ʻano like ʻole i nā ʻano āpau o ka hana mechanical, paʻakikī ka mālama ʻana.

• Hiki i ke kaʻina hana pauka ke hoʻohui i kekahi mau ʻāpana i ke kaʻina hana, hiki ke mālama i nā kumukūʻai hoʻoili a me ka hui.

• Hiki ke hoʻopaʻa ʻia ka nui o nā ʻāpana o ka pauka, loaʻa kahi nui o nā pores i hoʻopili ʻia, a maʻa mau ʻia me 5% -20% ʻaila lubricating e hāʻawi i kahi pae o ka lubrication ponoʻī, a laila e hoʻomaikaʻi ai i ka pale ʻana.

• I ka hana ʻana i ka pauka metallurgy, i mea e maʻalahi ai ka wehe ʻana i nā ʻāpana mai ka make ma hope o ka hoʻokumu ʻana, ʻoi aku ka kiʻekiʻe o ka ʻili hana o ka make, i loaʻa i nā ʻāpana kahi hoʻopau modulation amplitude. Eia kekahi, hiki i ka pauka metallurgy structural parts ke electroplating, coating, heat treatment and other after treatment like mechanical parts.

Nā pōʻino: Ma muli o ke ola ʻana o nā pores koena, ʻoi aku ka haʻahaʻa o kona ductility a me ka waiwai o ka hopena ma mua o ka hoʻolei ʻana me ka hoʻohui kemika hoʻokahi, no laila e kaupalena ʻia ana kāna palapala noi.

ʻāpana metallurgy pauda

Alakaʻi hoʻolālā metala pauda

ʻO ke kaʻina hana metallurgy pauda hiki ke hana i nā ʻāpana i nā ʻano nui a me nā ʻano like ʻole, a ʻo ka nui o ka nui o nā ʻāpana i hiki ke hana ʻia ma muli o ka hiki ke paʻi.

ʻO ke ʻano ʻāpana maʻalahi loa e hana ʻia ma ke kaʻina hana metallurgy pauda ʻo ia ka mea like me ka nui ma ke ala kaomi. Hoʻokumu ʻia nā ʻāpana me nā lua ma ke ala kaomi me ka mandrel. He maʻalahi ke kaomi ʻana i nā kī a me nā ala kī ma ka ʻaoʻao kaomi, a ʻo nā hiʻohiʻona e like me nā grooves, nā lua, nā cones, nā kihi concave a me nā kaula ma kahi Angle i ke kuhikuhi kaomi ʻana ʻaʻole hiki ke kaomi ʻia e nā kaʻina hana metallurgy pauda. Eia naʻe, me ka ʻoi aku ka paʻakikī o ka hoʻoheheʻe ʻana hiki ke hana ʻia nā ʻāpana ʻano paʻakikī. Ua hoʻohui i kahi kumukūʻai.

Na Gears, ratchets a me nā kāmeka

He kūpono loa nā Gears, ratchets a me nā kāmeʻa no ka hana ʻana e nā kaʻina hana metallurgy pauka.

Nā pōmaikaʻi o ka hana ʻana i ka pauka metallurgy:

① ʻO ka pololei o ka nui o nā mea hana i ka hana nui he ʻano like.

② No ka mea, loaʻa i ka hui waiwai kekahi porosity, kōkua ia i ka holo pono ʻana o ka mea hana a hiki ke hoʻomaʻamaʻa iā ia iho.

③ Hiki ke hana ʻia nā mea hao pauka me ka Angle makapō.

Hiki ke hoʻohui ʻia nā ʻāpana a me nā ʻāpana ʻē aʻe e ke kaʻina hana metallurgy pauka.

⑤ Hiki ke hana i nā ʻano mea like ʻole.

⑥ Hana maʻalahi a me ke kumu kūʻai haʻahaʻa.

ʻO ka ʻae ʻana i ka pauka metala

ʻO ka nui o ka fluctuation ma waena o nā ʻāpana metallurgy pauka ke kumu nui ʻia e ka loli o ke kaomi kaomi.

I ka nānā 'ana i ke kaomi ho'okahi, 'oi aku ka nui o ka ho'ololi elastic lō'ihi o ke ku'i make ma mua o ka ho'onui elastic o ka make 'ole, no laila, 'oi aku ka nui o ka ho'omanawanui 'ana ma ka 'ao'ao kaomi.

Nā pilina mīkini:

△ ka kuʻi / △ ka make = 3L/D

Hōʻike ʻo D i ka nui radial awelika o ka lua o ke kumu hoʻohālike ʻino.

Hōʻike ʻo L i ka lōʻihi holoʻokoʻa o ke kuʻi make.

Pehea e hōʻemi ai i ka hoʻomanawanui dimensional?

Hiki ke hoʻomaikaʻi ʻia ka hoʻomanawanui ʻana o ka ʻāpana ma ka hoʻopau ʻana, ʻo ia ka hoʻokomo ʻana i ka ʻāpana sintered i ka make maikaʻi ʻole a paʻi me ka die punching, ʻo ia hoʻi, e kaomi hou i ka pau ʻana. ʻO ke kumu nui o ka hoʻopau ʻana ʻo ia ka hoʻoponopono ʻana i ka distortion i hana ʻia e ka sintering.

Mīkinio na apana metallurgy pauda

ʻO ke kumu nui o ka hoʻohana ʻana i nā ʻāpana metallurgy pauka ʻo ka hoʻokō ʻana i ka ʻoki liʻiliʻi, ʻaʻohe hana ʻoki, mālama i ka ikehu, mālama waiwai, hoʻemi i ke kumu kūʻai o nā ʻāpana. ʻAʻole maʻalahi nā ʻāpana metallurgy pauka e ʻoki e like me nā ʻāpana metala maʻamau. Ma muli o ka hana ʻoki intermittent i hana ʻia e nā pores i ka hoʻolālā waiwai, pōkole ke ola mea hana a ʻilihune ka ʻili o ka ʻāpana.

Maʻamau no ka hoʻoholo ʻana i ka machinability o ka pauka metallurgy: e hoʻoholo i ka machinability ma ke ana ʻana i ka helu o nā lua i hiki ke wili ʻia. ʻO ka waiwai o ke kila 1045 i kuhikuhi ʻia he 100, a hiki ke hoʻoholo ʻia ka helu machinability e kēia ʻano kumu.

Machinability rating = ka helu o nā puka i wili ʻia i ka sintering/ka helu o nā puka i wili ʻia ma 1045 kila ×100

Hoʻohui ʻia ʻo Mn, P, S a me nā mea hoʻohui ʻē aʻe i ka mea e hoʻomaikaʻi ai i ka machinability o nā ʻāpana metallurgy pauka. Hiki ke hoʻomaikaʻi ʻia nā waiwai ʻokiʻoki o nā mea hao pauka ma ke koho pono ʻana i nā mea hana ʻoki carbide a me ka geometry o nā mea hana.

Ka hopena o ka nui o nā mea ma luna o nā ʻāpana metallurgy pauda

I ka hana ʻana i nā ʻāpana ʻāpana metallurgy pauka, hoʻohana pinepine ʻia ka repressing a me ka sintering kiʻekiʻe e hoʻomaikaʻi i ka nui o nā ʻāpana, a ua hana ʻia nā ʻāpana hana e like meke ala kaʻina o ke kaomi ʻana -- hoʻopaʻa mua -- hoʻopaʻa -- hoʻopaʻa lua.Hiki ke hoʻonui ʻia ka mānoanoa o nā ʻāpana a hiki i kahi95%ʻo ka hao maʻamau ma ke kaomi hou ʻana, ka paʻi lua a me ke kaomi mahana.

ʻO ka hoʻopaʻa ʻana ua like ia me ka hoʻopau ʻana, ʻo ke kaomi kiʻekiʻe i hoʻohana ʻia i ka wā o ka hoʻopaʻa ʻana ʻo ia wale nō ka hoʻonui ʻana i ka mānoanoa holoʻokoʻa o ka ʻāpana, a ʻo ka sintering kiʻekiʻe e pili ana i ka re-sintering ma hope o ka hoʻopaʻa ʻana. Hiki ke hoʻomaikaʻi ʻia ka ikaika a me ka paʻakikī o nā ʻāpana hoʻolālā ma muli o ke kiʻekiʻe o ka waiwai o nā ʻāpana hana ma hope o ke kaomi hou ʻana a me ka sintering lua.

Kaʻina Hana Metala Paʻa

Hoʻohui kemika a me nā waiwai mechanical

ʻO nā ʻāpana metallurgy pauka i hana ʻia e ke kaʻina kaomi maʻamau a me ke kaʻina sintering he porous, a ʻoi aku ka haʻahaʻa o kā lākou mau mea mīkini ma mua o nā mea metala paʻa me ka ʻano kemika like i hana ʻia e nā ʻano hana maʻamau. I mea e hoʻomaikaʻi ai i nā waiwai mechanical o ka pauka metallurgy structural parts:

I kēia manawa kamea maka paudame nā mea hoʻohuihui: ka pauka hao, ka pauka keleawe a me ka pauka graphite i hui pū ʻia, ka pauka hao, ka pauka nickel, ka pauka graphite i hui pū ʻia, ka pauka hao, ka pauka hao phosphorus i hui pū ʻia, ka pauka i hui ʻia, i ka pauka kila a me ka pauka kila kila.

ʻO nā kaʻina hana hana i hoʻohana ʻia: kaomi - hoʻopaʻa ʻana, kaomi - pre-sintering - repressing - sintering, pumehana kaomi - sintering, hot pressing, hot forging a pēlā aku.

ʻO ka ulu ʻana o nā ʻāpana metallurgy pauda

ʻO ke ʻano o ka hoʻomohala ʻana o ia mau mea, ʻo ia ka hōʻemi a hoʻopau ʻana i nā pores koena i loko o ka mea, a hoʻomohala i nā mea hao i hoʻohui ʻia me ka chromium, manganese, titanium, silicon a me nā mea ʻē aʻe e hoʻomaikaʻi ai i nā waiwai mechanical o ka mea a hoʻonui i ke kahua noi.
