Kaʻina Hana Hoʻomaʻamaʻa Wela ma ka Hana Aluminum

1) Hoʻopili a maʻamau

Hoʻohana ʻia ka Annealing a me ka hoʻomaʻamaʻa ʻana no ka mea wela alumini palaka. Hoʻopili pinepine ʻia ke kila kalapona a me ke kila kila me ka nui o ka carbon ma mua o 0.5% i mea e hōʻemi ai i ko lākou paʻakikī a maʻalahi hoʻi e ʻoki; hoʻohana ʻia ke kila kalapona a me ke kila kila me ka ʻiʻo kalapona ma lalo o 0.5% e pale aku i ka pili ʻana i ka pahi ke haʻahaʻa loa ka paʻakikī. A hoʻohana i ka lāʻau maʻamau. Hiki i ka Annealing a me ka normalizing ke hoʻomaʻemaʻe i ka palaoa a me ka hoʻolālā like, a hoʻomākaukau no ka mālama wela ma hope. Hoʻonohonoho pinepine ʻia ka Annealing a me ka normalizing ma hope o ka hana ʻia ʻana o ka blank a ma mua o ka hana ʻino.

2) Lapaʻau ʻelemakule

Hoʻohana nui ʻia ka mālama ʻana i ka wā kahiko e hoʻopau i ke koʻikoʻi kūloko i hana ʻia i ka hana blank a me ka mīkini.

I mea e pale aku ai i ka ukana nui o ka lawe ʻana, no nā ʻāpana me ka pololei maʻamau, ua lawa ia e hoʻonohonoho i hoʻokahi lapaʻau kahiko ma mua o ka pau ʻana. Eia nō naʻe, no nā ʻāpana me nā koi kikoʻī kiʻekiʻe, e like me ka pahu o ka mīkini boring jig, a me nā mea ʻē aʻe, pono e hoʻonohonoho ʻia ʻelua a i ʻole kekahi mau kaʻina hana lapaʻau. ʻAʻole pono nā ʻāpana maʻalahi i ka lapaʻau kahiko.

Ma waho aʻe o ka hoʻolei ʻana, no kekahi mau ʻāpana kikoʻī me ka rigidity maikaʻi ʻole, e like me ka screw precision, i mea e hoʻopau ai i ke koʻikoʻi kūloko i hana ʻia i ka wā o ka hoʻoili ʻana a hoʻopaʻa i ka pololei o ka hana ʻana o nā ʻāpana, ua hoʻonohonoho pinepine ʻia nā ʻano lapaʻau kahiko ma waena o ka mīkini paʻakikī a me ka semi-finishing. No kekahi mau ʻāpana shaft, pono e hoʻonohonoho ʻia ka lāʻau kahiko ma hope o ke kaʻina hana hoʻopololei.

3) Hoʻopiʻi a hoʻonā

ʻO ka hoʻopaʻa ʻana a me ka hoʻopaʻa ʻana e pili ana i ka wela wela ma hope o ke kinai ʻana. Hiki iā ia ke loaʻa kahi ʻano like ʻole a me ka hoʻonaninani sorbite, kahi hoʻomākaukau no ka hoʻohaʻahaʻa ʻana i ka deformation i ka wā o ka quenching surface a me ka mālama nitriding. No laila, hiki ke hoʻohana ʻia ka quenching a me ka tempering e like me ka preheat treatment.

Ma muli o ka ʻoi aku ka maikaʻi o nā ʻāpana mechanical piha o ka quenching a me ka tempering parts, hiki ke hoʻohana ʻia e like me ke kaʻina hana wela wela no kekahi mau ʻāpana ʻaʻole koi i ka paʻakikī kiʻekiʻe a me ke kūpaʻa.

ʻO ke kumu o ka hoʻomaʻamaʻa wela hope ʻo ia ka hoʻomaikaʻi ʻana i nā waiwai mechanical e like me ka paʻakikī, ke kūpaʻa a me ka ikaika. ʻO kāna kaʻina hana wela e pili ana i ka quenching, carburizing a quenching, a me ka mālama nitriding.

1) Ke kinai ana

Hoʻokaʻawale ʻia ka Quenching i ka quenching surface a me ka quenching holoʻokoʻa. I waena o lākou, ua hoʻohana nui ʻia ka hoʻopau ʻana o ka ʻili ma muli o kona liʻiliʻi liʻiliʻi, oxidation a me ka decarburization, a ʻo ka quenching ili pū kekahi i nā pono o ka ikaika o waho kiʻekiʻe a me ke kūpaʻa ʻaʻahu maikaʻi, ʻoiai e mālama ana i ka paʻakikī o loko a me ke kūpaʻa ikaika. I mea e hoʻomaikaʻi ai i nā ʻano mechanical o nā ʻāpana hoʻoheheʻe ʻana i ka ʻili, pono pinepine ka mālama ʻana i ka wela e like me ka quenching a me ka tempering a i ʻole ka normalizing e like me ka mālama ʻana i ka wela. ʻO kāna ala kaʻina maʻamau: blanking, forging, normalizing, annealing, rough machining, quenching and tempering, semi-finishing, surface quenching, hoʻopau.

2) Carburizing a kinai

Carburizing a me quenching mea e hoʻonui i ke kalapona maʻiʻo o ka ili papa o ka hapa mua, a ma hope o quenching, ka ili papa loaa kiʻekiʻe paakiki, oiai ka mea nui e malama mau i kekahi ikaika a me ka kiʻekiʻe toughness a me ka plasticity. Hoʻokaʻawale ʻia ʻo Carburizing i ka carburizing holoʻokoʻa a me ka carburizing hapa. Ke hana ʻia ka carburizing hapa, pono e lawe ʻia nā ana anti-seepage no nā ʻāpana non-carburizing. No ka mea ʻo ka carburizing a me ka hoʻopau ʻana i hana i ka deformation nui, a ʻo ka hohonu o ka carburizing ma waena o 0.5 a me 2 mm, ua hoʻonohonoho ʻia ke kaʻina hana carburizing ma waena o ka semi-finishing a me ka hoʻopau ʻana.

ʻO ke ala kaʻina maʻamau: blanking, forging, normalizing, rough machining, semi-finishing, carburizing and quenching, hoʻopau. Ke hoʻohana ka ʻāpana ʻole o ka carburizing a me ka hoʻopau ʻana i ke kaʻina hana o ka wehe ʻana i ka papa carburized keu ma hope o ka hoʻonui ʻana i ka palena, pono e hoʻonohonoho ʻia ke kaʻina hana o ka wehe ʻana i ka papa carburized ma hope o ka carburizing a me ke kinai ʻana, ma mua o ke kinai ʻana.

3) Lapaʻau nitriding

ʻO ka Nitriding ke kaʻina o ka hoʻokomo ʻana i nā ʻātoma nitrogen i loko o kahi ʻili metala e loaʻa ai kahi papa o nā pūhui me ka nitrogen. Hiki i ka papa nitriding ke hoʻomaikaʻi i ka paʻakikī, ke kūpaʻa ʻana, ka ikaika luhi a me ke kūpaʻa corrosion o ka ʻili o ka ʻāpana. Ma muli o ka haʻahaʻa o ka mahana mālama nitriding, liʻiliʻi ka deformation, a lahilahi ka papa nitriding, maʻamau ʻaʻole ʻoi aku ma mua o 0.6 ~ 0.7mm, pono e hoʻonohonoho ʻia ke kaʻina hana nitriding e like me ka hiki. I mea e hōʻemi ai i ka deformation i ka wā o ka nitriding, ʻo ia ka mea maʻamau e lawe i ka wela wela kiʻekiʻe no ka hoʻomaha ʻana i ke kaumaha.
