Pūtu Hanganga Kounga-Teitei
Ngā Pūtu Upoko Hex Noa
Ko te nuinga o ēnei pūtu he pūtu taratara taumata-C, ā, he iti noa iho ko ngā pūtu tika taumata-A me te taumata-B. He iti ake te kaha, ā, he maha ngā wā ka whakamahia hei whakapiri rangitahi, hei hononga rānei ki ngā wāhi tuarua e pikau ana i te kawenga.
Ngā Tawhā Matua:
E tutuki ana ēnei i ngā paerewa pērā i te GB/T 5780-2000 (miro wāhanga) me te GB/T 5781-2000 (miro katoa). Ko ngā whakatakotoranga miro e kapi ana i te M5-M64. Ko ngā tohu mahi ko te 3.6, 4.6, me te 4.8. Hei tauira, ko te kaha kume ingoa o te pūtu momo 4.8 he 400MPa me te kaha hua ingoa o te 320MPa. Ko te nuinga o te rauemi he maitai hanganga waro Q235. Ko ngā tohu A me B he pūtu tino tika, e tuku ana i te tika o ngā āhuatanga engari he nui ake ngā utu. Ko ngā pūtu momo C he pūtu matotoru, he iti ake te tika o te miihini engari he iti ake ngā utu; koinei ngā pūtu noa e whakamahia whānuitia ana i roto i ngā hanganga maitai.
Ngā tono:
He pai mō te whakapiri rangitahi i ngā hanganga maitai, pērā i te whakanoho me te hono i ngā wāhanga hanganga maitai i te wā hanga; he pai hoki mō ngā hanganga tuarua e mau ana i te kawenga, pērā i ngā tautoko hanganga maitai iti, te honohono i ngā wāhanga kāore e mau ana i te kawenga, me ngā hononga i roto i ngā hanganga maitai ka taea te wetewete i muri mai.
Ngā pūtu pane hexagonal nui, kaha rawa
He mea nui ēnei hei whakapiripiri i roto i ngā wāhanga matua o ngā hanganga maitai, e whakamahia ana i roto i ngā takirua hononga (kei roto ko te pūtu kotahi, te nati kotahi, me ngā whakamātao e rua). He nui atu te mahi me te tika o ā rātou whakapiripiri i ērā o ngā pūtu noa.
Ngā tawhā matua:
E tutuki ana i te paerewa GB/T 1228-2006; ko ngā tohu mahi ko te nuinga o te 8.8 me te 10.9. Ko te kaha kume o ngā pūtu reanga 10.9 he 1040-1240 N/mm², ko te kaha tuku kāore i raro iho i te 940 N/mm², ā, ko te pakeke Vickers kei waenga i te 312 me te 367. Ko te kaha kume o ngā pūtu reanga 8.8 he 830-1030 N/mm² me te kaha tuku he 660 N/mm². Ko te nuinga o te wā he mea hanga ki te maitai waro reo, ki te maitai koranu rānei, ā, me whakamahana kia pai ake ai ō rātou āhuatanga. Ko ētahi pūtu kaha-teitei ka tukinotia ki te whakapūkara me ētahi atu maimoatanga ārai-waikura.
Ngā horopaki e tika ana:
He pai mō ngā wāhanga matua e mau ana i te kawenga o ngā hanganga maitai, pērā i te hononga kurupae maitai i roto i ngā piriti, ngā hononga pūnga i roto i ngā hanganga anga maitai whare teitei, te whakau hanganga matua o ngā pourewa tuku hiko, me te whakau i ngā wāhanga e mau ana i te kawenga i roto i ngā hanganga maitai wheketere nui. He tino teitei ngā whakaritenga mō te pumau me te haumaru o te hononga i roto i ēnei āhuatanga. Ka taea e ngā pūtu pane hexagonal nui te whakatutuki i te whakakī tika o te taipana, me te whakawhirinaki ki te waku hei whakawhiti i ngā kawenga me te whakarite i te kaha katoa o te hanganga ki te mau i te kawenga.
Ngā Āhuatanga Noa me ngā Whakatūpato Whakamahinga
Ngā Painga Noa:
Mā te hoahoa pane hexagonal ka māmā ake te whakamahi me te whakau i te kī, ā, he pai mō te tāutanga mīhini me te tāutanga ā-ringa. Ko te nuinga ka whakamahia me ngā nati hexagonal me ngā whāriki hei whakapai ake i te hiri me te pumau o te hononga. Ko ētahi ka tukuna ki te whakawera wera, ki ētahi atu maimoatanga ārai-waikura rānei hei whakaroa i te roa o te ātete ki te waikura mō te whakamahinga o waho.
Ngā Whakatūpato Whakamahinga:
Kaua e whakaranua ngā momo pūtu rerekē. Hei tauira, kāore e taea te whakamahi i tētahi pūtu kaha teitei 10.9 me tētahi nati noa 4.8. Me tino whakahaere te taipana o ngā pūtu kaha teitei i te wā tāutanga; me noho te hapa o te kī taipana ki roto i te ±5% kia kore ai e tino kukū, ka pakaru pea te pūtu, ka iti rānei te kukū, ka pā ki te kaha o te hononga. Me tiaki te rokiroki mai i te ua me te makuku kia kore ai e waikura, e kino rānei ngā miro. Mena kāore e hototahi te pūtu me te nati, ka tino āraia te whakamahi.
