Ka hoʻomaʻemaʻe hoʻomaʻemaʻeʻo ia ke kaʻina hana o ka wehe ʻana i nā hemahema o ka ʻili o ka forgings me nā ʻano hana mechanical a kemika. I mea e hoʻomaikaʻi ai i ka maikaʻi o ka ʻili o nā forgings, hoʻomaikaʻi i nā kūlana ʻokiʻoki o nā forgings a pale i nā hemahema o ka ʻili mai ka hoʻonui ʻana, pono ia e hoʻomaʻemaʻe i ka ʻili o nā billets a me nā forgings i kēlā me kēia manawa i ka hana forging.
I mea e hoʻomaikaʻi ai i ka maikaʻi o ka ili onā kalaiwa, hoʻomaikaʻi i nā kūlana oki onā kalaiwaa pale aku i nā hemahema o ka ʻili mai ka hoʻonui ʻana, pono e hoʻomaʻemaʻe i ka ʻili o nā billet anā kalaiwai kēlā me kēia manawa i kakaʻina forging. Ka hao haohoʻomāhana maʻamau ma muake kalaiwa aname ka palaki kila a i ʻole kahi mea hana maʻalahi e wehe i ka pālākiō oxide. Hiki ke hoʻomaʻemaʻe ʻia ka blank me ka nui o ka ʻāpana e ka wai kiʻekiʻe. Hiki ke hoʻoneʻe ʻia nā unahi ma nā palaka anu ma ka pickling a i ʻole ka puhi ʻana (pellets). ʻOi aku ka liʻiliʻi o ka unahi nonferrous alloy oxide, akā ma mua a ma hope o ka hoʻomaʻemaʻe ʻana i ka hoʻomaʻemaʻe ʻana, ka ʻike kūpono a me ka wehe ʻana i nā hemahema o ka ʻili. ʻO nā hemahema o ka ʻili o ka billet a i ʻole forgings ka nui o nā māwae, nā ʻōpala, nā ʻōpala a me nā inclusions. Inā ʻaʻole i wehe ʻia kēia mau hemahema i ka manawa, e loaʻa iā lākou nā hopena maikaʻi ʻole i ke kaʻina hana forging ma hope, ʻoi aku hoʻi ma ka alumini, magnesium, titanium a me kā lākou mau ala. Hoʻomaʻemaʻe pinepine ʻia nā hemahema i ʻike ʻia ma hope o ka ʻohi ʻana i nā mea hoʻoheheʻe non-ferrous me nā faila, scrapers, grinders a me nā mea hana pneumatic. Hoʻomaʻemaʻe ʻia nā hemahema o ka hoʻoheheʻe ʻana i ke kila e ka pickling, sand blasting (pana), shot blasting, roller, vibration a me nā ʻano hana ʻē aʻe.

ʻAka hoʻomaʻemaʻe

Ka wehe ʻana i nā ʻokikene metala ma o nā hopena kemika. No ka mea liʻiliʻi a me ka liʻiliʻi-nui forgings e hoʻouka pinepine ʻia i loko o ka hīnaʻi ma nā ʻāpana, ma hope o ka wehe ʻana i ka ʻaila, pickling corrosion, holoi ʻana, hoʻomaloʻo a me nā kaʻina hana ʻē aʻe. 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. ʻO ke kaʻina hana hoʻoheheʻe kemika pickling e hoʻopuka i nā kinoea ʻino, no laila, pono e loaʻa i ka lumi pickling kahi mea hoʻopau. Pono ke koho ʻana i nā mea hoʻoheheʻe metala ʻē aʻe e like me nā waiwai metala, a e hoʻohana i ke kaʻina hana pickling (ka mahana, ka manawa a me ke ʻano hoʻomaʻemaʻe).

Hoʻomaʻemaʻe ʻana i ke one (pana) a me ka hoʻomaʻemaʻe ʻana
Me ka ea compressed e like me ka mana o ka sandblasting (pana), hana i ke one a kila paha pana i hana kiʻekiʻe-wikiwiki neʻe (sandblasting hana kaomi o 0.2 ~ 0.3Mpa, pana peening hana kaomi o 0.5 ~ 0.6Mpa), jet i ka forging ili i e hahau i ka unahi oxide. ʻO ka puhi ʻana i ka pana ma ke kiʻekiʻe kiʻekiʻe (2000 ~ 30001r/min) ka hoʻohuli ʻana i ka ikaika centrifugal o ka impeller, ke kī kila i ka ʻili forging e kīkē ai i ka unahi oxide. ʻO ka lepo Sandblasting, ka hana haʻahaʻa haʻahaʻa, ke kumukūʻai kiʻekiʻe, ʻoi aku ka hoʻohana ʻana no nā koi ʻenehana kūikawā a me nā mea hana kūikawā (e like me ke kila kila, titanium alloy), akā pono e hoʻohana i nā hana ʻenehana hoʻoneʻe lepo. He maʻemaʻe ke kiʻi kiʻi, 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 no kāna hana kiʻekiʻe a me ka hoʻohana haʻahaʻa.
Hoʻomaʻemaʻe ʻia ka pana peening a me ka pana ʻana, i ka manawa like, kikeke i ka pālākiō oxide, hana paʻakikī ka hana ʻana o ka ʻili, e hoʻomaikaʻi i ke kūpaʻa luhi o nā ʻāpana. No ka forgings ma hope o quenching a quenching a me ka hoʻomaʻamaʻa ʻana, ʻoi aku ka koʻikoʻi o ka hana paʻakikī i ka hoʻohana ʻana i ka pana kila nui, hiki ke hoʻonui ʻia ka paʻakikī e 30% ~ 40%, a hiki i ka mānoanoa o ka papa paʻakikī ke hiki i 0.3 ~ 0.5mm. I ka hana ʻana e like me nā mea a me nā koi ʻenehana o ka forgings e koho i nā mea like ʻole a me ka nui o ka nui o ka pana kila. Hiki ke uhi ʻia ka hoʻohana ʻana i ke one pahū (pana) a me ka pana ʻana e hoʻomaʻemaʻe i ka forgings, nā māwae ʻili a me nā hemahema ʻē aʻe. No laila, pono e hoʻohana i ka ʻike kīnā magnetic a i ʻole ka nānā ʻana i ka fluorescence (e ʻike i ka nānā kino a me ke kemika o nā hemahema) e nānā i nā hemahema o ka ʻili o ka forgings.

ka hāʻule ʻana
ʻO nā forgings, i loko o ka pahu kaʻawili, e kuʻi a wili kekahi i kekahi no ka wehe ʻana i ka unahi oxide a me ka burr mai ka mea hana. Hoʻohana kēia ʻano hoʻomaʻemaʻe i nā mea maʻalahi a maʻalahi, akā nui ka leo. He kūpono no ka liʻiliʻi liʻiliʻi a me ka liʻiliʻi liʻiliʻi e hiki ke hoʻokō i kekahi hopena a ʻaʻole maʻalahi ke hoʻololi. ʻAʻohe abrasive ka hoʻomaʻemaʻe pahu, hoʻohui wale i ka hao triangular a i ʻole ke anawaena pōpō kila o 10 ~ 30mm o ka hoʻomaʻemaʻe non-abrasive, ʻo ka nui o ka hui ʻana e wehe i ka unahi oxide. ʻO ka mea ʻē aʻe e hoʻohui i ke one quartz, nā ʻāpana huila wili a me nā mea abrasive ʻē aʻe, ka sodium carbonate, ka wai kopa a me nā mea hoʻohui ʻē aʻe, ma ka wili ʻana no ka hoʻomaʻemaʻe.

Hoʻomaʻemaʻe haʻalulu
I ka forgings hui me kekahi hapa o abrasives a me nā mea hoʻohui, waiho i loko o ka vibrating ipu, e ka vibration o ka ipu, no laila, i ka workpiece a me ka abrasive wili kekahi i kekahi, ka ili o ka forgings oxide a burr aku. He kūpono kēia ʻano hoʻomaʻemaʻe no ka hoʻomaʻemaʻe ʻana a me ka hoʻoliʻiliʻi ʻana i nā forging precision liʻiliʻi a me waena.
