1. Ka wehewehe ʻana o ka hana anu
ʻO Cold forging, ʻike ʻia hoʻi he cold volume forging, he hana hana a me ke ʻano hana.ʻO ke kumu like me ke kaʻina hana stamping, ʻo ke kaʻina hana hoʻoheheʻe anuanu i haku ʻia me nā mea waiwai, nā mold a me nā mea hana.Akā ʻo ka mea i ka hana stamping ka mea nui o ka pā, a ʻo ka mea i loko o ka hana hoʻoheheʻe anuanu ʻo ia ka uea disk.Ua kapa ʻia ʻo Iapana (JIS) ʻo cold forging (cold forging), Kina (GB) i kapa ʻia ke poʻo anu, ma waho o ka hale hana screw e like me ke kāhea ʻana i ke poʻo.
2. Nā manaʻo kumu o ka hana anu
ʻO ka hana anu anu e pili ana i ka metala recrystallization wela ma lalo o nā leo like ʻole.Wahi a ke kumumanaʻo o ka metalology, ʻokoʻa ka mahana recrystallization o nā mea metala like ʻole.T = (0.3 ~ 0.5) T hehee.ʻO ka wela o ka recrystallization liʻiliʻi o nā metala ferrous a me nā metala ʻole.ʻOiai i ka mahana wela a i ʻole ka mahana maʻamau, ʻaʻole i kapa ʻia ke kaʻina hana o ke kēpau a me ka tin i ke anuanu forging, akā wela forging.Akā ʻo ka hao, ke keleawe, ka alumini e hana ana i ka hana ʻana ma ka lumi wela hiki ke kapa ʻia ʻo ke anuanu.
I nā metala, ua kapa ʻia ka hana ʻana o nā mea i wela ma luna o ka mahana recrystallization (ma kahi o 700 ℃ no ke kila).
No ke kila forgings, ka recrystallization wela ma lalo a kiʻekiʻe ma mua o maʻamau ka wela forging i kapaia mahana forging.
Nā pōmaikaʻi o ke poʻo anu (extrusion)
I ka hana hoʻopaʻa ʻana, ʻo ke poʻo anu (extrusion) ʻenehana kahi ʻenehana hana nui.ʻO ke poʻomanaʻo anuanu (extrusion) no ka ʻāpana o ka hoʻoili ʻana i ke kaomi metala.I ka hana ʻana, i ka mahana maʻamau, hoʻohana ʻia ka metala i ka ikaika o waho, i mea e hoʻokumu ʻia ai ka metala i loko o ka mold i koho mua ʻia, ua kapa ʻia kēia ʻano he poʻo anu.
ʻO ka hana ʻana o kēlā me kēia mea paʻa ʻaʻole ia he ala deformation o ke poʻo anu, hiki ke ʻike ʻia i ke kaʻina o ke poʻo anu, me ka hoʻonāukiuki ʻana i ka deformation, akā hele pū ʻia me ka extrusion i mua a i hope, extrusion composite, ʻoki ʻoki, ʻōwili a me nā mea ʻē aʻe. deformation ala.No laila, ʻo ka inoa o ke poʻo anu i ka hana ʻana he inoa maʻamau wale nō, a pono e kapa ʻia ʻo ke poʻo anu (squeeze) me ka pololei.
ʻO ke poʻo anuanu (extrusion) he nui nā pono, kūpono ia no ka hana nui o nā mea hoʻopili.ʻO kāna mau mea maikaʻi nui e pili ana i kēia mau mea:
ʻO ke kiʻekiʻe o ka hoʻohana ʻana i ke kila, ke poʻo anuanu (squeeze) kahi ʻano o ka liʻiliʻi, ʻaʻohe ʻoki, e like me ke koʻokoʻo hoʻoponopono, cylinder head hex socket screws, hex head bolt machining method, the utilization rate of steel in 25% ~ 35%, a wale nō me ke poʻomanaʻo anu (squeeze), a hiki i kona helu hoʻohana ke kiʻekiʻe e like me 85% ~ 95%, he poʻo wale nō, huelo a me ke poʻo hex i ʻoki ʻia kekahi o ke kaʻina hana.
ʻO ka huahana kiʻekiʻe: ke hoʻohālikelike ʻia me ka ʻokiʻoki maʻamau, ʻoi aku ka nui o ke poʻo anu (extrusion) e hana ana i ka pono.
ʻO nā waiwai mechanical maikaʻi: ke poʻo anuanu (extrusion) ka hana ʻana i nā ʻāpana, no ka mea ʻaʻole i ʻoki ʻia ka fiber metala, no laila ʻoi aku ka maikaʻi o ka ikaika ma mua o ka ʻoki ʻana.
He kūpono no ka hana ʻakomi: ʻo nā mea hoʻopaʻa (me kekahi mau ʻāpana ʻano kūikawā) kūpono no ke poʻo anu (extrusion) hana ʻo ia nā ʻāpana symmetrical, kūpono no ka mīkini poʻomanaʻo kiʻekiʻe kiʻekiʻe, ʻo ia ke ʻano nui o ka hana nui.
Ma kahi huaʻōlelo, ʻo ke ʻano o ke poʻomanaʻo (extruding) kahi ʻano hana kaʻina me ka pōmaikaʻi hoʻokele waiwai kiʻekiʻe, i hoʻohana nui ʻia i ka ʻoihana paʻa.ʻO ia hoʻi kahi ʻano hana hana holomua i hoʻohana nui ʻia ma ka home a ma waho me ka hoʻomohala nui.
