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 i kahi o 0.75 iniha 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 i ʻike ʻia ma ka wahi nui. 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 kiʻi hohonu, paʻa ka hakahaka ma waena o ka make kiʻi a me ka mea paʻa hakahaka, ʻoiai e huki ana ke kiʻi kiʻi i nā mea i loko o ke kiʻi make, e kahakaha ana a puni ka radius huki e hana ai i ka shell. 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 ikaika ka hoʻolālā ʻana o kāu mea hana. Pono ka mānoanoa o kāu mau kāmaʻa mold e kū i ka huki ʻana me ka ʻole o ka hoʻopaʻa ʻana. ʻO ke kākoʻo ma lalo o ka kāmaʻa make he kila paʻa, a ʻo nā pine alakaʻi make e nui ka nui e pale ai i ka neʻe ʻana o ka neʻe ʻana o ka ʻaoʻao o luna a me lalo e make i ka wā o ke kau ʻana.
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.
