I mea e hoʻomaikaʻi ai i ka maikaʻi o ka ʻili o ka forgings, hoʻomaikaʻi i nā kūlana ʻoki o ka forgings a pale i nā hemahema o ka ʻili mai ka hoʻonui ʻana, pono ia e hoʻomaʻemaʻe i ka blank a me nā forgings i kēlā me kēia manawa i ka wā forging production. Hoʻomaʻemaʻe pinepine ʻia nā mea hao hao me kahi pulupulu kila a i ʻole mea hana maʻalahi ma mua o ka hana ʻana ma hope o ka hoʻomehana ʻana. Hiki ke hoʻomaʻemaʻe ʻia ʻo Billet me ka nui o ka ʻāpana e ka wai kiʻekiʻe.

ʻAka hoʻomaʻemaʻe

Hoʻohana ʻia ka hopena kemika no ka wehe ʻana i ka metala oxide. Hoʻokomo pinepine ʻia nā palaka liʻiliʻi a me ka liʻiliʻi i loko o ka hīnaʻi a hoʻopau ʻia ma o nā kaʻina hana e like me ka wehe ʻana i ka ʻaila, pickling a me ka corrosion, holoi a hoʻomaloʻo. Loaʻa i ke ʻano pickling nā hiʻohiʻona o ka hana hana kiʻekiʻe, ka hopena hoʻomaʻemaʻe maikaʻi, ʻaʻohe deformation o forgings a me ke ʻano palena ʻole. I ke kaʻina hana o ka pickling chemical reaction, he mea hiki ʻole ke hana i nā kinoea hoʻopōʻino i ke kino kanaka. No laila, pono e loaʻa kahi mea hoʻopau i loko o ka lumi pickling. Pono ke koho ʻana i nā mea metala like ʻole e like me nā waiwai metala e koho ai i ka ʻakika like ʻole a me ka ratio haku mele, pono e hoʻohana ʻia ke kaʻina hana pickling e pili ana (ka mahana, ka manawa a me ke ʻano hoʻomaʻemaʻe).

Hoʻomaʻemaʻe ʻana i ke one (pana) a me ka hoʻomaʻemaʻe ʻana

ʻO ka hoʻoneʻe ʻana o ke one (pana) i hoʻoikaika ʻia e ka ea paʻa e hoʻoneʻe i ke one a i ʻole ke kila pana e neʻe i ka wikiwiki (ʻo ke kaomi hana o ka puhi ʻana i ke one he 0.2-0.3mpa, a ʻo ke kaomi hana o ka puhi ʻana he 0.5-0.6mpa), ka mea i hoʻopuʻi ʻia ma ka ke kalai ʻana i ka ʻili e holoi i ka unahi oxide. Ke hilinaʻi nei ka puhi ʻana i ka pana i ka ikaika centrifugal o ka impeller wili i ka wikiwiki kiʻekiʻe (2000 ~ 30001r/min) e pana i ka pana kila ma kaili forginge kikeke i ka unahi oxide. ʻO ka lepo hoʻomaʻemaʻe hoʻomaʻemaʻe ʻana i ke one, haʻahaʻa haʻahaʻa hana hana, ke kumu kūʻai kiʻekiʻe, hoʻohana ʻia no nā koi ʻenehana kūikawā a me nā mea hana kūikawā forgings (e like me ke kila kila, titanium alloy), akā pono e hoʻohana i nā ʻenehana hoʻoneʻe lepo maikaʻi. He maʻemaʻe ka pana ʻana, aia kekahi mau hemahema o ka hana haʻahaʻa a me ke kumukūʻai kiʻekiʻe, akā ʻoi aku ka maikaʻi o ka hoʻomaʻemaʻe. Hoʻohana nui ʻia ʻo Shot Blasting ma muli o kāna hana kiʻekiʻe a me ka hoʻohana haʻahaʻa.

ʻAʻole hiki i ka peening pana a me ka pana pana ke wehe wale i ka ʻili oxide, akā hoʻoikaika i ka ʻili o ka forging, kahi mea e pono ai ka hoʻomaikaʻi ʻana i ka mana anti-fatigue o nā ʻāpana. No ka forgings ma hope o ka quenching a quenching a me ka hoʻomaʻamaʻa ʻana, ʻoi aku ka nui o ka hana paʻakikī i ka wā e hoʻohana ʻia ai ka pana kila nui, hiki ke hoʻonui ʻia ka paʻakikī e 30% ~ 40%, a hiki i ka 0.3 ~ 0.5 ka mānoanoa o ka papa paʻakikī. mm. I ka hana ʻana, pono e koho ʻia ke kiʻi kila me nā mea like ʻole a me ka nui o ka palaoa e like me nā mea a me nā koi ʻenehana o forgings. Inā hoʻomaʻemaʻe ʻia nā mea hoʻoheheʻe ʻia e ka puhi ʻana (pana) a me ka pana ʻana, hiki ke hūnā ʻia nā māwae o luna a me nā hemahema ʻē aʻe, a hiki ke hoʻomaka ʻole ka nānā ʻana. No laila, pono nā ʻano e like me ka nānā ʻana i ka magnetic a i ʻole ka fluorescence (e ʻike i ka nānā kino a me ke kemika o nā hemahema) pono e nānā i nā hemahema o ka ʻili o ka forging.

ka hāʻule ʻana

I loko o ka pahu kaʻawili, hoʻopaʻa ʻia nā forgings a i ʻole ka lepo e wehe i ka ʻili oxide a me nā burrs mai ka mea hana. Hoʻohana kēia ʻano hoʻomaʻemaʻe i nā mea maʻalahi a maʻalahi, akā walaʻau. He kūpono no nā mea liʻiliʻi a me ka liʻiliʻi liʻiliʻi e hiki ke hoʻopaʻa i kekahi hopena akā ʻaʻole hiki ke hoʻololi. Maʻemaʻe ka huila me ka ʻole o nā abrasives, me nā poloka hao triangular a i ʻole nā ​​pōpō kila me ke anawaena o 10 ~ 30mm me ka ʻole abrasives, ʻo ka mea nui ma ka hopena like ʻole e hoʻomaʻemaʻe i ka unahi oxide. ʻO ka mea ʻē aʻe e hoʻohui i ka abrasive e like me ke one quartz, ka huila wili ʻōpala, ka sodium carbonate, ka wai kopa a me nā mea hoʻohui ʻē aʻe, ma ka wili ʻana e hoʻomaʻemaʻe.

Hoʻomaʻemaʻe haʻalulu

Hoʻohui ʻia kekahi hapa o nā abrasives a me nā mea hoʻohui i nā forgings a waiho ʻia i loko o ka pahu vibrating. Ma ka haʻalulu ʻana o ka ipu, ʻāwili ʻia ka mea hana a me ka abrasive, a ʻo ka ʻili oxide a me nā burrs ma luna o ka ʻili o ka forgings. He kūpono kēia ʻano hoʻomaʻemaʻe no ka hoʻomaʻemaʻe ʻana a me ka hoʻoliʻiliʻi ʻana i nā forging precision liʻiliʻi a me waena.
