Mekameka Roera 12A
Ngā Āhuatanga me ngā Painga o te Hua
1. Hanganga tino tika me te rauemi kaha-teitei
He mea hanga te mekameka roera 12A ki te maitai koranu kounga teitei, ki te maitai waro rānei, ā, ka pāngia e te tukanga whakamahana tino pakari hei whakarite i te kaha me te ātete ki te kakahu o te mekameka. He pai te urutau o te pereti mekameka o roto me te ringaringa, te pereti mekameka o waho me te pine, ā, he pai te urutau o te roera me te ringaringa, me te ringaringa me te pine. Mā tēnei hoahoa ka taea e te mekameka te huri ngāwari i te wā e whakamahia ana, me te whakaiti i te kakahu.
2. Te mahi tuku pai
Ko te teitei o te mekameka roera 12A he 19.05mm, ko te whānui o te roera he 11.91mm, ko te whānui o roto o te hononga o roto he 12.57mm, ā, ko te whānui o te pine he 5.94mm. Mā ēnei hoahoa āhua tika ka tino pai te hononga i waenga i te mekameka me te porotiti, ā, ka tutuki te tuku hiko whai hua. Ka taea e tōna kawenga kume toharite te eke ki te 41.5kN, ā, ko te kawenga kume mutunga he 31.8kN, ka taea te tu atu i tētahi kawenga mahi nui.
3. Te pakari me te iti o te utu tiaki
Kua whakapakeketia te mata o ngā pine me ngā ringaringa o te mekameka roera 12A kia mau tonu ai te mahi pumau i raro i te pēhanga teitei, kia tū atu ai hoki i te pēhanga e puta mai ana i te kawenga. Hei tāpiri, he mea hanga ngā roera ki te maitai titanium waro-teitei me ngā ringaringa kore hononga, ka tineia hei whakapai ake i te ātete ki te kakahu me te ātete ki te kume. Ehara i te mea ka roa ake te ora o te mekameka i tēnei hoahoa, engari ka whakaitihia hoki ngā utu tiaki.
4. Whānui te whakamahinga
He pai te mekameka roera 12A mō ngā momo āhuatanga ahumahi, tae atu ki te hanga mīhini, te tukatuka kai, ngā taputapu tākai, ngā mīhini ahuwhenua me te hanga motuka. Ahakoa he hoahoa rarangi kotahi, rarangi rua, rarangi maha rānei, ka taea e ia te whakatutuki i ngā hiahia tuku o ngā taputapu rerekē.
5. Te maimoatanga mata kanorau
He maha ngā momo maimoatanga mata e tukuna ana e te mekameka roera 12A, pērā i te pupuhi pupuhi, te whakapūmau, te whakakikorua nikara, me ētahi atu, hei urutau ki ngā taiao mahi rerekē me ngā whakaritenga ārai-waikura. Ehara i te mea ka whakarei ake ēnei maimoatanga i te ātete waikura o te mekameka, engari ka whakapai ake hoki i tōna āhua.
6. Tiwhikete Paerewa o te Ao
E tutuki ana te mekameka roera 12A i ngā paerewa o te ao pēnei i te ISO, ASME/ANSI, me te JIS, kia taea ai te whakamahi whānui me te whakawhiti puta noa i te ao. Mā tēnei hoahoa paerewa ka taea e te mekameka te mahi pai i waenga i ngā taputapu me ngā porotiti rerekē.
