ʻO nā pono a me nā pōʻino o ka pauka metala a me nā forgings Ⅰ

No ka manawa lōʻihi, ua hoʻohālikelike nā ʻenekinia a me nā mea kūʻai aku i ka pauka metallurgy me nā kaʻina hoʻokūkū.ʻO nā ʻāpana metala pauka a me nā ʻāpana i hoʻopaʻa ʻia, e like me nā hoʻohālikelike ʻē aʻe o nā ʻano hana hana, kōkua ia e hoʻomaopopo i nā pono a me nā hemahema o kēlā me kēia kaʻina.Hāʻawi ka Powder Metallurgy (PM) i nā pono he nui āu e noʻonoʻo ai - maopopo kekahi, ʻaʻole nui kekahi.ʻOiaʻiʻo, i kekahi mau hihia, he koho maikaʻi paha ka forging.E nānā i nā hoʻohana kūpono a me nā hoʻohana ʻana i ka pauka metala a me nā ʻāpana forged:

1. Pauda metala a me ka forgings

Mai ka lilo ʻana i kumu nui, ua lilo ka pauka metallurgy i mea hoʻonā no ka hana ʻana i nā ʻāpana liʻiliʻi i nā kūlana he nui.I kēia manawa, hiki paha iā ʻoe ke hoʻopaʻapaʻa ua hoʻololi ʻia ka nui o nā castings i hiki ke hoʻololi ʻia e PM.No laila, he aha ka palena aʻe no ka hoʻohana piha ʻana i nā metala pauka?Pehea e pili ana i nā ʻāpana hoʻopunipuni?He kiko'ī loa ka pane i kāu noi.ʻO nā waiwai pili o nā mea forging like ʻole (ʻo ka forgings kekahi ʻāpana o lākou), a laila hōʻike i ke kūlana o ka metala pauka kūpono no ka wehewehe.Ua hoʻokumu kēia i ke kumu no ka PM o kēia manawa, a ʻoi aku ka mea nui, ka PM hiki.E nānā i kahi e hilinaʻi ai ka 80% o ka ʻoihana metala pauda i ka hao hao, keleawe phosphor, a pēlā aku.I ka pōkole, inā ʻoe e hoʻolālā e hoʻohana maʻamau iron-copper-carbon e hoʻolālā i nā ʻāpana, a laila ʻaʻole pono ʻoe i ka metallurgy pauka.Eia nō naʻe, inā ʻoe e noiʻi i nā mea ʻoi aku ka holomua a me nā kaʻina hana, hiki i ka PM ke hāʻawi i ka hana āu e pono ai ma ke kumukūʻai haʻahaʻa loa ma mua o ka forgings.

2. E nana pono kakou i kekahi o na pono a me na hemahema o ka metala pauda a me na apana kalaiia.

A. ʻāpana metala pauda metallurgy

1. Pono o ka pauda metallurgy:

Hiki ke hanaʻia nā'āpana me nā mea hiki ke hāʻawi i ka lawelawe wela kiʻekiʻe a me ka lōʻihi kiʻekiʻe, a ua ho'ēmiʻia ke kumukūʻai.E noʻonoʻo e pili ana i ke kila kila, e pili ana i nā wela kiʻekiʻe i nā ʻōnaehana exhaust, etc.

Hiki ke mālama i ka huahana kiʻekiʻe o nā ʻāpana, ʻo nā ʻāpana paʻakikī.

Ma muli o ka ʻupena shapeability o ka pauka metallurgy, ʻaʻole pono ka hapa nui o lākou i ka machining.ʻO ka liʻiliʻi o ka hana lua, ʻo ia ka emi ʻana o nā koina hana.

Hiki i ka hoʻohana ʻana i ka pauka metala a me ka sintering ke hoʻokō i kahi kiʻekiʻe o ka mana.ʻAe kēia i ka hoʻoponopono maikaʻi ʻana i nā waiwai electromagnetic, density, damping, paʻakikī a paʻakikī.

Hoʻomaikaʻi nui ka sintering wela kiʻekiʻe i ka ikaika tensile, kulou i ka ikaika luhi a me ka ikehu hopena.

2. Nā hemahema o ka pauda metallurgy:

Loaʻa nā ʻāpana PM i nā palena nui, hiki ke hana i kekahi mau hoʻolālā hiki ʻole ke hana.ʻO ka paʻi nui loa ma kēia ʻoihana ma kahi o 1,500 tons.Hoʻopili kēia i ka nui ʻāpana maoli i kahi pālahalaha ma kahi o 40-50 square inches.ʻOi aku ka ʻoiaʻiʻo, ʻo ka awelika nui o ka paʻi i loko o 500 tons, no laila e ʻoluʻolu e hana i kahi hoʻolālā no kāu hoʻomohala ʻana.

Paʻakikī paha ka hana ʻana i nā ʻāpana me nā ʻano paʻakikī.Eia naʻe, hiki i nā mea hana metala akamai loa ke lanakila i kēia pilikia a kōkua pū iā ʻoe e hoʻolālā.

ʻAʻole ikaika nā ʻāpana e like me ka hao i hoʻolei ʻia a i ʻole nā ​​ʻāpana paʻa.
