ʻO ka hana hoʻopololei ʻana he ʻano hana hoʻoheheʻe ʻia e hoʻohana ana i ka ʻōpala e hana i kahi pāhaka palahalaha i loko o kahi ʻāpana hāmama.E like me kekahi o nā kaʻina hana stamping nui, hoʻohana nui ʻia ke kau ʻana.Hiki ke hoʻohana ʻia ke kaʻina hana e hana ai i ka cylindrical, rectangular, stepped, spherical, conical, parabolic a me nā ʻāpana pā irregular.Inā hui pū ʻia me nā kaʻina hana stamping ʻē aʻe, hiki iā ia ke hana i nā ʻāpana me nā ʻano paʻakikī..

E hoʻohana i nā mea hana stamping no ka hoʻopololei ʻana i nā huahana, e like me: ka hoʻopololei ʻana, ka hana hou ʻana, ka hoʻihoʻi ʻana a me ka hana ʻana i ka lahilahi, a me nā mea ʻē aʻe. o ka mea palahalaha i loko o ka lua o ka poni concave e hana ia i ipu me ka lalo.ʻO ka hana ʻana o ka paia ʻaoʻao o ka ipu e like me ke kuhikuhi ʻana he hana hoʻopololei maʻemaʻe, aʻo ka hana ʻana o nā pahu conical (a i ʻole pyramid), nā ipu hemispherical, a me nā ipu ʻili parabolic pū kekahi me ka hoʻonui ʻana i ka hana.

Ka hana hou ʻana: ʻo ia hoʻi, no nā huahana hohonu i hiki ʻole ke hoʻopau ʻia i hoʻokahi kaʻina kikoʻī, pono ia e hoʻopololei i ka huahana i hana ʻia ma hope o ka hoʻopili ʻana e hoʻonui i ka hohonu o ka ipu i hana ʻia.

Ka hana ʻana i ka ʻōniʻoniʻo: E hoʻihoʻi hou i ka mea hana i hoʻolōʻihi ʻia i ke kaʻina hana mua, lilo ka ʻaoʻao o loko o ka mea hana i ka ʻaoʻao o waho, a ʻoi aku ka lahilahi o ka hana ʻana i ka liʻiliʻi o waho.I loko o ka lua o ka concave mold me ka liʻiliʻi liʻiliʻi o waho anawaena, ua hoʻemi ʻia ke anawaena o waho o ka ipu me ka lalo, a ua thinned ka mānoanoa o ka pā i ka manawa like, ʻaʻole ia e hoʻopau wale i ka deviation o ka mānoanoa o ka pā, akā. hoʻomāmā i ka ʻili o ka ipu.

Hōʻike ʻia kēia mau ʻano ʻelua o ka hoʻopaʻa ʻana a me ke kau ʻana i ka wā e hoʻohana ai i nā mea hana stamping:

1. Ka hana kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻiʻoniʻoni + (Round kiʻi): ka hohola ʻana o nā huahana cylindrical.ʻO ka flange a me ka lalo i ke ʻano mokulele, ʻo ka paia ʻaoʻao o ka cylinder he axisymmetric, a ua puʻunaue like ka deformation ma ka ʻāpana like, a ua pohō ka lauoho ma ka flange e kumu i ka deformation kiʻi hohonu.

2. Ellipse kiʻi hana + (Ellipse kiʻi): ʻO ka deformation o ka lauoho ma ka flange he tensile deformation, akā ʻo ka nui o ka deformation a me ka ratio deformation e hoʻololi like me ke ʻano contour.ʻO ka nui o ka curvature, ʻoi aku ka nui o ka deformation plastic o ka hulu hipa, a ʻoi aku ka liʻiliʻi o ka curvature, ʻoi aku ka liʻiliʻi o ka deformation plastic o ka hulu hipa.
