He aha ka wehe ʻana?

Open forging e pili ana i ke kaʻina hana o ka forging e hoʻohana ana i nā mea hana maʻalahi maʻalahi a i ʻole e hoʻopili pololei i nā mana waho ma waena o nā anvils luna a me lalo o nā mea hana forging e hoʻololi i ka billet a loaʻa ke ʻano geometric pono a me ka maikaʻi o loko. Ua kapa ʻia nā forgings me ka hoʻohana ʻana i ke ʻano forging open.

ʻO ka wehe ʻana o ka forging ka mea nui e hana i nā ʻāpana liʻiliʻi o ka forgings, a hoʻohana i nā mea hana forging e like me nā hamare a me nā kaomi hydraulic e hana a hoʻoponopono i nā blanks, e loaʻa ai nā forgings kūpono. ʻO nā kaʻina hana maʻamau o ka hoʻoheheʻe ʻia ʻana e like me ka huhū, ka lōʻihi, ke kuʻi, ka ʻoki ʻana, ke kuʻi ʻana, ka wili ʻana, ka hoʻoneʻe ʻana, a me ka hana ʻana. Hoʻohana ʻo Open forging i ke ʻano hana forging wela.

ʻO ke kaʻina hana forging hāmama nā kaʻina hana kumu, kaʻina kōkua, a me ke kaʻina hoʻopau.

ʻO nā kaʻina hana maʻamau o ka wehe ʻana e pili ana i ka huhū, elongation, kuʻi, kulou, ʻoki, wili, hoʻoneʻe, a me ka forging. I ka hana maoli, ʻo nā kaʻina hana maʻamau i hoʻohana ʻia ʻo ka huhū, elongation, a me ke kuʻi.

Nā kaʻina hana kōkua: nā kaʻina hana pre deformation, e like me ke kaomi ʻana i nā iwi āpau, kaomi ʻana i nā ʻaoʻao ingot kila, ʻoki ʻana i nā poʻohiwi, etc.

Ke kaʻina hana hoʻopau: ʻO ke kaʻina hana e hōʻemi ai i nā hemahema o ka ʻili o ka forgings, e like me ka wehe ʻana i ka like ʻole a me ka hana ʻana i ka ʻili o nā forgings.

Pono:

(1) He maʻalahi loa ka Forging, hiki ke hana i nā ʻāpana liʻiliʻi ma lalo o 100kg a me nā ʻāpana kaumaha a hiki i 300t;

(2) ʻO nā mea hana i hoʻohana ʻia he mau mea hana maʻamau maʻalahi;

(3) ʻO ka hoʻoulu ʻana ʻo ia ka deformation lohi o ka billet ma nā ʻāpana like ʻole, no laila, ʻoi aku ka liʻiliʻi o ka tonnage o nā mea hana forging e pono ai no ka hana ʻana i ka forging like ma mua o ka forging model;

(4) Nā koi haʻahaʻa haʻahaʻa no nā mea hana;

(5) Pōkole hana hana.

Nā hemahema a me nā palena:

(1) ʻOi aku ka haʻahaʻa o ka hana ʻana ma mua o ke kumu hoʻohālike;

(2) He ʻano maʻalahi ko ka Forgings, haʻahaʻa haʻahaʻa ka pololei, a me nā ʻili ʻākala; He kiʻekiʻe ka ikaika o ka poʻe hana a koi i kahi kiʻekiʻe kiʻekiʻe o ka ʻenehana loea;

(3) ʻAʻole maʻalahi ka hoʻokō mechanization a me ka automation.

Hoʻokumu pinepine ʻia nā hemahema ma muli o ke kaʻina hana hana hewa ʻole

ʻO nā hemahema i hoʻokumu ʻia e ke kaʻina hana hana hewa ʻole e loaʻa i kēia mau mea:

ʻO nā kīʻaha nui: ʻO nā kīʻaha nui ke kumu ma muli o ke kiʻekiʻe o ka wela forging mua a me ka lawa ʻole o ka deformation deformation, kiʻekiʻe ka wela forging hope, a i ʻole ka deformation deformation e hāʻule ana i loko o ka ʻāpana deformation koʻikoʻi. ʻO ka hoʻololi nui ʻana o ka alumini alumini, ka hopena i ke ʻano o ke ʻano; Ke haʻahaʻa loa ka mahana deformation o nā ʻāpana wela kiʻekiʻe, hiki i ke kūkulu ʻia ʻana o nā hale deformation hui ʻia ke kumu i nā kīʻaha coarse. ʻO ka nui o ka palaoa e hōʻemi i ka plasticity a me ka paʻakikī o ka forgings, a hoʻemi nui i kā lākou hana luhi.

ʻO ka nui o ka palaoa like ʻole: ʻO ka nui ʻole o ka palaoa e pili ana i ka ʻoiaʻiʻo ʻo kekahi mau ʻāpana o ka forging he mau kīʻaha koʻikoʻi, a ʻo nā mea ʻē aʻe he liʻiliʻi liʻiliʻi. ʻO ke kumu nui o ka nui ʻole o ka palaoa, ʻo ia ka deformation ʻole o ka billet, e hopena i nā pae like ʻole o ka ʻāpana palaoa, a i ʻole ka deformation deformation o nā wahi kūloko e hāʻule ana i loko o ka ʻāpana deformation koʻikoʻi, a i ʻole ka paʻakikī o ka hana kūloko o nā mea wela wela, a i ʻole. ʻo ka hoʻopaʻa ʻana o ka palaoa i ka wā e kinai ai a me ka wela. ʻO ke kila pale wela a me nā mea wela wela ke maʻalahi i ka nui o ka palaoa. ʻO ka nui ʻole o ka palaoa e hoʻemi nui i ka hana paʻa a me ka luhi o nā forgings.

ʻO ke ʻano paʻakikī anu: I ka wā o ka hoʻopaʻa ʻana i ka deformation, ma muli o ka haʻahaʻa haʻahaʻa a i ʻole ka wikiwiki o ka hoʻololi ʻana, a me ka hoʻomaloʻo wikiwiki ʻana ma hope o ka hoʻopaʻa ʻana, ʻaʻole hiki ke hoʻomau ʻia ka palupalu i hana ʻia e ka recrystallization i ka hoʻoikaika ʻana (paʻakikī) i hoʻokumu ʻia e ka deformation, e hopena i ka paʻa ʻana o ka ʻāpana. ʻano hoʻololi anuanu i loko o ka forging ma hope o ka forging wela. ʻO ka hele ʻana o kēia hui e hoʻomaikaʻi i ka ikaika a me ka paʻakikī o nā forgings, akā e hōʻemi i ka plasticity a me ka paʻakikī. ʻO ka paʻakikī paʻakikī paʻakikī hiki ke hana i nā māwae.

Nā māwae: ʻO ka hana ʻana i nā māwae ke kumu ma muli o ke koʻikoʻi tensile koʻikoʻi, ke koʻikoʻi shear, a i ʻole ke koʻikoʻi tensile ʻē aʻe i ka wā o ka hana ʻana. Loaʻa ka māwae ma kahi me ke koʻikoʻi kiʻekiʻe a me ka mānoanoa lahilahi o ka billet. Inā loaʻa nā microcracks ma ka ʻili a me loko o ka billet, a i ʻole he mau hemahema o ka hoʻonohonoho ʻana i loko o ka billet, a inā ʻaʻole kūpono ka mahana o ka hoʻomaʻamaʻa ʻana, e hopena i ka emi ʻana o ka plasticity material, a inā ʻoi aku ka wikiwiki o ka deformation a i ʻole ka ʻOi aku ka nui o ka deformation deformation, ʻoi aku ma mua o ka ʻae ʻia ʻana o ka mea i ʻae ʻia, hiki mai nā māwae i nā kaʻina hana e like me ka coarsening, elongation, punching, hoʻonui, kūlou, a extrusion.
