Mea paipu kila humuhumu ʻole: Hana ʻia ka paipu kila humuhumu ʻole me ka ingot kila a i ʻole ka billet paipu paʻa ma o ka perforation i loko o ka paipu ʻino, a laila ʻōwili wela, ʻōwili anu a huki anu paha. Hana ʻia ka mea me ke kila kalapona kiʻekiʻe e like me 10,20, 30, 35,45, kila kūkulu haʻahaʻa e like me16Mn, 5MnV a i ʻole ke kila hui e like me 40Cr, 30CrMnSi, 45Mn2, 40MnB ma ka ʻōwili wela a i ʻole ka ʻōwili anu. Hoʻohana nui ʻia nā paipu humuhumu i hana ʻia me ke kila kalapona haʻahaʻa e like me 10 a me 20 no nā paipu lawe wai.
ʻO ka maʻamau, ua māhele ʻia ke kaʻina hana o nā paipu kila humuhumu i ʻelua ʻano: ke kaʻina hana huki anu a me ke kaʻina hana ʻōwili wela. Eia kahi ʻike holoʻokoʻa o ke kaʻina hana o nā paipu kila humuhumu anu a me nā paipu kila humuhumu wela:
ʻO ke kaʻina hana paipu kila humuhumu anu (ʻōwili anu): hoʻomākaukau ʻana a me ka nānā ʻana i ka paipu billet → hoʻomehana ʻana i ka paipu billet → perforation → ʻōwili paipu → hoʻomehana hou ʻana i ka paipu kila → ana (hoʻemi) ke anawaena → mālama wela → hoʻopololei ʻana i ka paipu i hoʻopau ʻia → hoʻopau → nānā (ʻaʻole luku, kino a me ke kemika, nānā bench) → mālama
Pono e hoʻokomo mua ʻia nā paipu kila wili ʻole i ʻōwili anu ʻia i ʻekolu ʻōwili mau, a pono e hana i nā hoʻāʻo nui ma hope o ka extrusion. Inā ʻaʻohe māwae pane ma ka ʻili, pono e ʻoki ʻia ka paipu poepoe e kahi mīkini ʻoki a ʻokiʻoki i loko o nā ʻāpana me ka lōʻihi o hoʻokahi mika. A laila e komo i ke kaʻina hana annealing. Pono e hoʻopaʻa ʻia ka annealing me ka wai waikawa. I ka wā pickling, e makaʻala inā he nui nā pehu ma ka ʻili. Inā he nui nā pehu, ʻo ia hoʻi ʻaʻole i kūlike ke ʻano o ka paipu kila me nā kūlana like.
ʻO ke kaʻina hana paipu kila wili wela (extruded): billet paipu poepoe → hoʻomehana → perforation → ʻōwili oblique ʻekolu-ʻōwili, ʻōwili mau a extrusion paha → wehe ʻana i ka paipu → ana (a hōʻemi paha) ke anawaena → hoʻoluʻu → paipu billet → hoʻopololei → hoʻāʻo kaomi wai (a ʻike paha i nā hemahema) → māka → mālama
ʻO ka ʻōwili wela, e like me ka inoa e hōʻike nei, he mahana kiʻekiʻe no ka ʻāpana i ʻōwili ʻia, no laila he liʻiliʻi ke kūpaʻa deformation a hiki ke hoʻokō ʻia ka nui o ka deformation. ʻO ke kūlana hāʻawi o nā paipu kila wili ʻole i ʻōwili wela ʻia e ʻōwili wela ʻia a mālama ʻia me ka wela ma mua o ka hāʻawi ʻana. Nānā ʻia ka paipu paʻa a wehe ʻia nā hemahema o ka ʻili, ʻoki ʻia i ka lōʻihi e pono ai, kau ʻia ma ke kikowaena o ka ʻaoʻao hope o ka ʻaoʻao perforated o ka paipu, a laila hoʻouna ʻia i ka umu hoʻomehana no ka hoʻomehana ʻana a perforated ma ka perforator. ʻOiai e perforating ana, wili ia a neʻe mau i mua. Ma lalo o ka hana a nā wili a me ke poʻo, hana mālie kahi lua i loko o ka paipu, i kapa ʻia he paipu ʻino. Ma hope o ka wehe ʻana o ka paipu, hoʻouna ʻia i ka mīkini ʻōwili paipu aunoa no ka ʻōwili hou ʻana, a laila hoʻoponopono ʻia ka mānoanoa o ka paia e ka mīkini pae, a hoʻoholo ʻia ke anawaena e ka mīkini ana e hoʻokō i nā koi kikoʻī. Ma hope o ka mālama ʻana i ka ʻōwili wela, pono e hana i kahi hoʻokolohua perforation. Inā nui loa ke anawaena perforation, pono e hoʻopololei a hoʻoponopono ʻia, a laila lepili ʻia a waiho ʻia i loko o ka mālama.
Hoʻohālikelike ʻana o ke kaʻina hana kaha anu a me ke kaʻina hana ʻōwili wela: ʻOi aku ka paʻakikī o ke kaʻina hana ʻōwili anu ma mua o ke kaʻina hana ʻōwili wela, akā ʻoi aku ka maikaʻi o ka maikaʻi o ka ʻili, ke ʻano, a me ka pololei o ka dimensional o nā papa kila i ʻōwili anu ʻia ma mua o nā papa i ʻōwili wela ʻia, a ʻoi aku ka lahilahi o ka mānoanoa o ka huahana.
Nui: ʻOi aku ka nui o ke anawaena o waho o ka paipu wili wela ma mua o 32mm, a ʻo ka mānoanoa o ka paia he 2.5-200mm. Hiki i ke anawaena o waho o ka paipu kila wili anu a hiki i ka 6mm, hiki i ka mānoanoa o ka paia a hiki i ka 0.25mm, hiki i ke anawaena o waho o ka paipu paia lahilahi a hiki i ka 5mm, a ʻoi aku ka mānoanoa o ka paia ma mua o 0.25mm (ʻoi aku ka liʻiliʻi ma mua o 0.2mm), a ʻoi aku ka pololei o ke anawaena o ka wili anu ma mua o ka wili wela.
ʻAno: ʻOiai ʻoi aku ka liʻiliʻi o ka mānoanoa o ka paia o ka paipu kila wili anu ma mua o ka paipu kila wili wela, ʻoi aku ka mālamalama o ka ʻili ma mua o ka paipu kila wili wela mānoanoa, ʻaʻole ʻino loa ka ʻili, a ʻaʻole nui nā burrs o ke anawaena.
Ke kūlana hoʻouna: Hāʻawi ʻia nā paipu kila i ʻōwili wela ʻia i ke ʻano wela a i ʻole ka mālama wela ʻia, a hāʻawi ʻia nā paipu kila i ʻōwili anu ʻia i ke ʻano mālama wela.
