ʻO nā mea hana a me nā mea hana i hoʻohana ʻia no ka forging manuahi he maʻalahi, ākea a haʻahaʻa.Hoʻohālikelike ʻia me ka hoʻolei ʻana i ka blank,manuahi ke kalaiwa anahoʻopau i ka lua shrinkage, shrinkage porosity, porosity a me nā hemahema ʻē aʻe, i loaʻa i ka blank nā mea mechanical kiʻekiʻe.Hoʻopaʻamaʻalahi ke ʻano a maʻalahi i ka hana.No laila, he mea nui ia i ka hana ʻana i nā mīkini kaumaha a me nā ʻāpana koʻikoʻi.
Kahua noi
Kuʻu wale forgingshoʻomalu ʻia e ka hana lima o ke ʻano a me ka nui onā kalaiwa, pela kahana pololeiHe haʻahaʻa, nui ka haʻawina hana, nui ka hana, ʻaʻole kiʻekiʻe ka huahana, no laila hoʻohana nui ʻia i ka hana hoʻokahi, liʻiliʻi.
1) Pono ka nui o ka billet a me ka waena waena e like me nā wahi hana o kēlā me kēia kaʻina hana, e like me ke kiʻekiʻe-diameter ratio (H/D) o nā mea ma mua o ka huhū ʻana he 2-2.5, a me ka ʻikepili empirical o ka hoʻololi ʻana i ka pauku i ke kaha kiʻi. i waho.
2) pono e koho i ka hoʻololi o ka blank nui i loko o kanā kaʻina hana forging,no ka laʻana, hoʻemi ʻia ke kiʻekiʻe hakahaka i ka wā e kuʻi ai, ma ke ʻano he 1.1 mau manawa o ke kiʻekiʻe forging;Ke hoʻonui ʻia ke kiʻekiʻe reaming kumu kumu.
3) ka ʻāpana ʻāpana, pono e hōʻoia i kēlā me kēia ʻāpana o ka forging i lawa ka leo, e like me ka step shaft, crankshaft a i ʻole gear boss billet, e hana maikaʻi i ka hāʻawi ʻana i ka leo o kēlā me kēia ʻāpana.
4) I ka manawake kalaiwa aname nā ahi he nui, pono e nānā i ka hiki ke hoʻomehana i kēlā me kēia ahi i waenakonu.Ina kanā kalaiwahuki lōʻihi loa i ka hoʻomaka ʻana, ʻaʻole lawa ka nui o ka umu e hoʻokomo i loko o nā forging lōʻihi i ka wā hoʻomehana lua.I mea e hōʻoiaʻiʻo ai i ka nui a me ka maikaʻi o ka forgings, pono e uku nui ʻia i ka deformation o ke ahi ma hope o Z a me ka mālama ʻana i ka mahana o ka forging mua a me ka hope ma hope o Z.
5) Pono e hōʻoia i ka lawa o ka ʻoki ʻana ma hope o ka hoʻopau ʻana ma hope o Z, a pono e nānā ʻia i:
(1) No ka mea, ma ke kaʻina hana o ke kaomi ʻana i ka poʻohiwi, ka hoʻoneʻe ʻana, ka kuʻi ʻana a me nā mea ʻē aʻe, aia kahi ʻano o ke kaha kiʻi ʻana a me ka emi ʻana ma ka hakahaka, pono e waiho i kahi haʻawina ʻaʻahu ma ke kaʻina waena;
(2) Hoʻopaʻa lōʻihinā lāʻau kalai(e like me crankshafts, etc.) anā kalaiwame nā poloka concave, no ka mea ʻaʻole hiki ke hoʻonāukiuki hou ʻia ka nui o ka lōʻihi, pono e manaʻo ʻia e hoʻonui iki ʻia ka nui o ka ʻaoʻao lōʻihi i ka lole a alakaʻi i waho o ka hoʻomanawanui.

Ke kalaiwa ana.
6) Ke koho ʻana i nā mea hana, pono nā keiki e hoʻohana i nā mea hana maʻamau.Ke nui ka pūʻulu hana, hiki ke hana ʻia nā mea hana kūikawā a i ʻole nā ​​​​pili kaila e hoʻomaikaʻi i ka maikaʻi a me ka hoʻopuka ʻana o nā forgings.
7) E like me ka nui a me ka maikaʻi o ka blank, koho i nā mea hana i loaʻa i ka hale hana.
