Ka ʻikepili o nā ʻāpana mīkini kikoʻī maʻamau: ka mīkini pā

Mahele 1. Nā hiʻohiʻona o nā ʻāpana pā

ʻO nā ʻāpana pā he mau ʻāpana me ka pā pālahalaha e like me ke kino nui, ʻo ia ka mea maʻamau me nā puka wili, nā ʻaoʻao kākoʻo liʻiliʻi, nā lua hāʻawi, nā ʻauwaʻa sila, nā kī hoʻonohonoho a me nā mea ʻē aʻe.

Māhele 2. Nā koi ʻenehana no nā ʻāpana pā

(1) Hoʻokaʻawale nui ʻia nā ʻāpana pālima hoʻomanawanui i ʻelua mau ʻāpana: hoʻohana ʻia kekahi ma ke ʻano he mea nānā a ʻo ia ka maʻamau no kēlā me kēia ʻāpana ana.He kiʻekiʻe ka pololei o ka ʻili, a ʻo ka pae hoʻomanawanui ʻo IT3 ~ IT4.ʻO ke koi e ʻike i ka pae ʻokoʻa o nā ʻāpana.Ma kahi o 3 manawa;ʻO nā ʻano ʻāpana ʻē aʻe i hoʻohana ʻia me nā ʻāpana nui, a koi ʻia ko lākou ʻae ʻana i ka ʻili he IT5 ~ IT6, ʻo ia ka pae kiʻekiʻe ma mua o nā ʻāpana nui a lākou e hoʻohālikelike ai.(2) Geometric tolerances No ka palahalaha, verticality, a me ka like like o nā ʻili nui e like me ka ʻili luna a me lalo, ka ʻili o waho, a me nā ʻili luna o nā ʻāpana pā, pono e kaupalena ʻia nā hewa i ka laulā hoʻomanawanui.
(3) ʻO ka ʻili o ka ʻili ʻO ka ʻili i hana ʻia o ka pā i nā koi o ka ʻili, i hoʻoholo ʻia ma muli o ka hana a me ka hoʻokele waiwai o ka hana ʻana, a me ka pololei o ka hoʻohana ʻana o ka huahana.ʻO ka roughness ili o nā mokulele mea hoʻokele maʻamau ʻo Ra0.2 ~ 0.6μm, a ʻo ka ʻili o nā ʻāpana mokulele ʻo Ra0.6 ~ 1.0um.

Māhele 3. Hoʻoponopono ʻenehana loiloi o nā ʻāpana pā

No nā ʻāpana me nā koi kikoʻī kiʻekiʻe, pono e hoʻokaʻawale ʻia ka roughing a me ka hoʻopau ʻana e hōʻoia i ka maikaʻi o nā ʻāpana.Hiki ke hoʻokaʻawale ʻia ka hana ʻana o nā ʻāpana pā i ʻekolu mau ʻanuʻu: wili ʻili (wili ʻia o ka maka hope, ʻeha ʻeha), wili semi-finish (milling semi-finish o ka maka hope, semi-fine boring, drilling and papping of ʻO kēlā me kēia puka wili), ka wili maikaʻi a me ka ʻoluʻolu maikaʻi, i kekahi manawa no ka hoʻokō ʻana i ke ʻano kiʻekiʻe kiʻekiʻe a me nā koi palahalaha, pono ke kaʻina hana wili.

Māhele 4. Ke koho mea no nā ʻāpana pā

(1) Nā lako o nā ʻāpana pā Ua hana pinepine ʻia nā ʻāpana pā i ka hao.No nā papa e koi ana i ka pololei kiʻekiʻe a me ka rigidity maikaʻi, hiki ke hoʻohana ʻia ke kila 45, 40Cr, a i ʻole ductile hao;no ka wikiwiki nui, nā papa hana kaumaha, hiki ke hoʻohana ʻia nā kila hao haʻahaʻa e like me 20CrMnTi20Mn2B, 20Cr, a i ʻole 38CrMoAI.
(2) Nā ʻāpana o nā ʻāpana pā Ma hope o ka hoʻomehana ʻana a me ka hana ʻana i nā blanks e like me ke kila 45, hiki ke hoʻokaʻawale ʻia ke ʻano o ka fiber o loko o ka metala ma ka ʻili e loaʻa ai ka ikaika tensile kiʻekiʻe, ka ikaika kulou a me ka ikaika torsion.Hiki ke hoʻohana ʻia nā hoʻoheheʻe no nā papa nui a i ʻole nā ​​​​papa me nā hale paʻakikī.

Māhele 5. Nā koi mālama wela no nā ʻāpana pā

1) Ma mua o ka hana ʻana, pono e hoʻomaʻamaʻa ʻia a i ʻole e hoʻopili ʻia ka forging roughness e hoʻomaʻemaʻe i nā ʻano o loko o ke kila, e hoʻopau i ke koʻikoʻi forging, e hōʻemi i ka paʻakikī o nā mea, a hoʻomaikaʻi i ka hana.
2) Hoʻonohonoho maʻamau ka hoʻopau ʻana a me ka hoʻomaʻamaʻa ʻana ma hope o ka wili ʻana a ma mua o ka wili semi-finishing no ka loaʻa ʻana o nā waiwai mechanical piha.
3) Hoʻonohonoho maʻamau ka hoʻopau ʻana i ka ʻili ma mua o ka pau ʻana, i hiki ke hoʻoponopono ʻia ka deformation kūloko i hana ʻia e ka quenching.4) Pono nā papa me nā koi kikoʻī kiʻekiʻe e hoʻomaʻamaʻa haʻahaʻa haʻahaʻa ma hope o ke kinai ʻana a i ʻole ka wili ʻana.
