Kumumanaʻo Hana o ka Mīkini Hoʻopau Cryogenic

I ka hoʻomau ʻana o ka hana ʻana i ka hana pololei ma waena o nā ʻoihana kaʻa, uila, aerospace a me nā waiwai kūʻai o kēlā me kēia lā, ua lilo ka ʻenehana hana hope kiʻekiʻe a me ka ʻole o ka hōʻino no nā ʻāpana i hoʻoheheʻe ʻia i koi nui no ka hoʻonui ʻana i ka hana. ʻO ka mīkini deflashing cryogenic, ma ke ʻano he mea wehe uila pololei nui, ua pani mālie i nā ʻano hana ʻoki lima kuʻuna, ʻoki mīkini a me nā ʻano wili abrasive, mahalo i kona pololei kiʻekiʻe, ʻaʻole hōʻino a me ka pono hana batch kiʻekiʻe. Hoʻohana nui ʻia no ka deburring a me ka wehe ʻana i ka uila o nā ʻāpana elastic a me ka pololei. Hoʻokaʻawale piha kēia ʻatikala i kāna loina hana, nā ʻano lako hana nui a me nā mea hana kūpono.

Kumumanaʻo Hana o ka Mīkini Hoʻopau Cryogenic

ʻO ke kumu hana koʻikoʻi o ka mīkini hoʻopau cryogenic e pili ana i kanā ʻano hoʻololi brittle haʻahaʻa o nā mea polymer, ke hoʻohana nei i ka hui pū ʻana o ka refrigeration cryogenic a me ka mechanical shot blasting e hoʻomaopopo ai i ka wehe ʻana o ka flash kūpono a pololei me ka ʻole e hōʻino i nā substrates workpiece.

I ka wā o ka hana maʻamau, hoʻouna mua ka mīkini i ka naikokene wai i loko o ke keʻena hana i hoʻopaʻa ʻia, e hoʻemi koke ana i ka mahana o loko i ka minus 80 ℃ a i ka minus 196 ℃. Hoʻokomo ʻia nā ʻāpana hana i hoʻoheheʻe ʻia me ka flash a me nā burrs i loko o ke keʻena haʻahaʻa mau. ʻO nā ʻāpana flash lahilahi a palupalu e hiki koke i ka mahana hoʻololi aniani a lilo i mea palupalu a paʻakikī, ʻoiai ke kino nui mānoanoa o ka workpiece e mālama mau ana i ka paʻakikī maikaʻi a me ke kūpaʻa o ke kūkulu ʻana ma lalo o ke kaiapuni haʻahaʻa like, e pale ana i ka deformation a i ʻole ka hōʻino ʻia.

Ma hope o ka hoʻopau piha ʻia ʻana o ka flash, hoʻopuehu ka ʻōnaehana pana pahū wikiwiki i loko o ka mīkini i nā mea hana ikaika a pololei e hoʻopā i ka ʻili o ka workpiece. Hoʻopau koke ʻia a kuʻi ʻia ka flash brittle a me nā burrs, ʻoiai ʻaʻole i hoʻopilikia ʻia ke kino workpiece paʻakikī. ʻO ka hope loa, hoʻopau ka mīkini i ka hoʻokaʻawale ʻakomi o nā workpieces a me nā ʻōpala ʻōpala, a e hoʻihoʻi nā ʻāpana i hana ʻia i ko lākou mau waiwai kino mua ma hope o ka hoʻi ʻana i ka mahana o ka lumi, me nā lihi laumania a ʻaʻohe burrs lua a i ʻole nā ​​​​kalai.

Ke hoʻohālikelike ʻia me nā ʻano hana kuʻuna, pale aku kēia loina hoʻoheheʻe kino haʻahaʻa i ka pala kemika, ka extrusion mechanical a me nā hewa ʻoki lima, e hōʻoiaʻiʻo ana i ka pololei o ka hana ʻana no nā ʻāpana hana batch.

Nā Mea Hana Kūpono

Ua kuhikuhi nui ʻia ka ʻenehana deflashing cryogenic, pili nui i nā mea me nā ʻano hoʻololi brittle haʻahaʻa haʻahaʻa. Uhi ia i ka hapa nui o nā kino elastic, nā plastics ʻenekinia a me nā mea alloy hapa, me nā māhele kikoʻī e pili ana penei:

1. Nā Mea Hana ʻAila a me Elastomer

ʻO kēia ke kahua noi ʻoi loa, me ka laholio kūlohelohe, ka laholio silicone, EPDM, neoprene, butyl rubber, polyurethane elastomer a me nā mea ʻē aʻe. Hiki i kēia mau mea palupalu a elastic ke ʻālohilohi i ka lihi i ka wā o ka hoʻopili ʻana a me ka hoʻoheheʻe ʻana i ka injection, a maʻalahi ka ʻoki kuʻuna e hana i ka deformation o ka lihi. Hiki i ka hana embrittlement haʻahaʻa ke wehe loa i ka flash me ka mālama ʻana i ka elasticity mua a me ka paʻakikī o nā ʻāpana laholio.

2. Nā Mea Hana Palakiko ʻenekinia

Pili i nā ʻano plastik ʻenekinia paʻakikī like ʻole i paʻakikī ke ʻoki lima, e like me ABS, PP, PE, PVC, nylon, POM, TPU a me nā mea plastik i hoʻololi ʻia. Hoʻopau pono ia i nā burrs molding a me ka parting line flash ma nā ʻāpana kūkulu plastik, nā pūpū i hoʻoheheʻe ʻia a me nā kia plastik, e hōʻoiaʻiʻo ana i nā lihi huahana laumania a ʻaʻohe burr.

3. Nā Mea Hoʻoheheʻe Make Alloy Māmā

He kūpono nō hoʻi ia no ka hoʻopau ʻana i ka zinc alloy, magnesium alloy a me nā ʻāpana make-casting māmā ʻē aʻe. Hiki i ke kaʻina hana hopena haʻahaʻa ke wehe i nā burrs liʻiliʻi i hana ʻia i ka wā o ka hoʻoheheʻe ʻana i ka make-casting me ka ʻole o ka ʻōpala ʻana i ka ʻili laumania o nā ʻāpana alloy, e hoʻokō ana i nā koi hiʻohiʻona kiʻekiʻe o nā ʻāpana kikoʻī lako.

4. Nā Mea Hana Hui Pū ʻia

Me nā composites rubber-plastic a me nā ʻāpana composite i hoʻoikaika ʻia i ka fiber hapa. Hiki i ka ʻenehana ke wehe koho i ka ʻili keu me ka ʻole o ka luku ʻana i ka ʻano composite o ka workpiece, e hoʻoponopono ana i ka pilikia paʻakikī o ka deburring heterogeneous composite parts.

Ka Waiwai Noi ʻOihana

I kēia manawa, ua lilo nā mīkini hoʻoheheʻe cryogenic i mau lako kākoʻo koʻikoʻi no nā ʻoihana hana kikoʻī e like me nā ʻōnaehana sila kaʻa, nā mea uila mea kūʻai aku, nā mea lapaʻau, nā aerospace a me nā huahana rapa a me ka plastik i kēlā me kēia lā. ʻOiai e hoʻomaikaʻi ana i ka hoʻopau ʻana o ka ʻili o ka huahana a me ka pololei o ka dimensional, hoʻemi nui lākou i nā kumukūʻai hana lima a me nā helu hemahema, a hoʻokō i ka hana ʻōmaʻomaʻo a me ka pono me ka ʻole o ka haumia a me ka ʻole o ka hōʻino, he hōʻailona koʻikoʻi ia o ka hoʻonui akamai ʻana o ka ʻenehana hana post-molding.
