Ke hoʻokumu ʻia i kahi make holomua, pili ka paʻa paʻa paʻa, nā kūlana paʻi, a me nā mea maka i ka hiki ke loaʻa nā hopena kikoʻī me ka ʻole o ka wrinkling.
Nīnau: Ke kiʻi nei mākou i nā kīʻaha mai ka papa 304 stainless steel. Ma ka hoʻomaka mua o kā mākou holomua holomua, huki mākou ma kahi o 0.75 iniha ka hohonu. Ke nānā au i ka mānoanoa o ka flange perimeter o ka blank, hiki ke kiʻekiʻe ka ʻokoʻa mai ka ʻaoʻao a hiki i ka ʻaoʻao e like me 0.003 iniha. He ʻokoʻa kēlā me kēia pā a ʻaʻole ʻike ʻia ma ka wahi nui o ka hana. Pehea e hiki ai iā mākou ke loaʻa i ke kīʻaha ʻano like ʻole me ka wīwī ʻole?
A: ʻIke wau i kāu nīnau e hāpai nei i ʻelua mau nīnau: ʻo ka mea mua, nā hoʻololi āu e loaʻa ai i ke kaʻina hana loteri, a ʻo ka lua, nā mea maka a me kā lākou mau kikoʻī.
ʻO ka nīnau mua e pili ana i nā hemahema o ka hoʻolālā ʻana, no laila, e nānā kākou i nā kumu.
Ma ke kaha ki'i hohonu, ho'okomo 'ia ka blank ma waena o ka make ki'i a me ka mea pa'a hakahaka, a'o ka pahu kaha ki'i e huki i ka mea i loko o ke kaha ki'i, e kaha ana a puni ka radius huki e hana ai i ka pūpū. ma lalo o ka huki ʻana o ke kuʻi kiko.
Aia ka palena ma waena o ke anawaena o ka pūpū a me ke anawaena blank ʻaʻole hiki ke hoʻokiʻekiʻe ʻia no ka hana kiʻi kūleʻa. Hoʻololi ʻia kēia palena e ka pākēneka elongation o ka mea. ʻO ka lula maʻamau ʻo 55% a 60% no ka huki mua ʻana a me 20% no kēlā me kēia kaha kaha kiʻi. pau ka hoʻolālā).
ʻO ke kaomi paʻa paʻa ʻole p he 2.5 N/mm2 no ke kila, 2.0 a 2.4 N/mm2 no nā ʻāpana keleawe a me 1.2 a 1.5 N/mm2 no nā alumini alumini.
ʻO nā ʻano like ʻole o ka mānoanoa flange e hōʻike pū ana ʻaʻole lawa ka ikaika o kāu hoʻolālā hāmeʻa. Pono e mānoanoa kou mau kāmaʻa mold e pale aku i ka huki ʻana me ka ʻole o ka hoʻopaʻa ʻana. ʻO nā kākoʻo ma lalo o ke kumu make he kila paʻa a ʻo nā pine alakaʻi mea hana pono e nui ka nui e pale ai i ka neʻe ʻana o nā ʻaoʻao ʻaoʻao o nā mea hana ma luna a me lalo i ka wā e hohola ai.
E nānā pū i kāu nūhou. Inā ʻeleʻele a paheʻe nā alakaʻi paʻi, ʻaʻole ia he mea nui inā ikaika kāu mea hana - ʻaʻole ʻoe e kūleʻa. ;ʻO kā lākou geometry a me ka hoʻopau ʻana i ka ʻili ke kūpono.
Eia kekahi, ʻoiai ke nānā aku nei nā mea kūʻai aku i ka 304L a me ka 304 maʻamau e like me ka hoʻololi ʻana, ʻo ka 304L ka koho ʻoi aku ka maikaʻi no ke kiʻi. ke ʻano i hana ʻia. He maʻalahi wale ka hoʻohana.
