Ngā wāhanga mīhini ahuwhenua: Ngā hea parau, ngā pereti hea parau ātete-kakahu
Ko te hea parau, hei wāhanga matua o te parau papa pokepoke, ka mahi tahi me te hea parau, ā, ka whakatau tika i te whai huatanga me te kounga o te parau. He mea hanga motuhake tēnei hua mō te parau ahuwhenua hou, ā, he pai mō ngā mahi tahi i ngā mara maroke, i ngā mara raihi, me ngā oneone uku. E whakapau kaha ana mātou ki te whakarato ki ngā kaiwhakamahi he hea parau kounga teitei e tuku ana i te ātete iti, te tango oneone tere, me te ātete roa ki te kakahu mā te tukatuka rauemi matatau me te hoahoa mata aerodynamic, e āwhina ana ki te whakatutuki i tētahi wheako parau whai hua me te penapena pūngao.
Ka whakamahia e tēnei hua te maitai boron kaha-teitei, te maitai koranu manganese-boron rānei hei rauemi turanga, ā, ka tukuna he tukanga whakamahana whānui hei whakarite i te pakeketanga me te pakari pai mai i te mata ki te pūtake. Ka whakamahia e ngā mata mahi matua te hangarau whakarewa paparanga ātete-kakahu, te hangarau whakapakari laser rānei, ka tutuki ai te pakeketanga o te mata o te HRC 50-55, neke atu rānei. Ka ātete pai tēnei ki ngā pānga kino me te kakahu whakakoi mai i ngā mea pakeke pērā i ngā kōhatu me ngā pakiaka rākau, ka roa ake te ora ratonga mā te 2-3 ngā wā ki te whakataurite ki ngā hea parau maitai noa, ā, ka whakaiti nui i te auau o te whakakapinga i te mara.
E whakamahia ana e mātou he hanganga mata piko kua āta whakaritea, e piri pono ana ki ngā mātāpono o te kinematics oneone. E toru ngā painga nui o tēnei hoahoa:
1, Te tango oneone pai rawa atu: Ka tātaihia te piko o te mata piko kia taea ai te tango wawe i ngā poraka oneone i te wā e piki ana, e huri ana hoki, kia tino pai ai mō ngā oneone uku me ngā taiao mahi makuku nui. Ka ārai i te piri me te aukati o te oneone, kia noho ma tonu ai te mata o te parau.
2, He penapena pūngao nui: Ka whakaitihia e te piko arataki kua arotauhia te ātete waku i waenga i te oneone me te hea parau, ka whakaitihia te ātete kukume tarakihana mā te 10%-15% i te hohonutanga me te tere parautanga kotahi, ā, ka whakaitihia te whakapaunga wahie.
3, He mahi whakapuru pai rawa atu: Ka taea e ia te huri tika i ngā taru mata, te kakau witi, me te tongi, ka tanumia ki raro i te paparanga oneone, ka whakatairanga i te pirau o ngā mea rauropi me te hanga i tētahi moenga purapura papatahi, ma mō te rui i muri mai.
E rua ngā kōwhiringa hanganga o tēnei raupapa parau: te whakaotinga whakaata (e tika ana mō ngā parau tere-rahi) me te whakaotinga papa (e tika ana mō ngā oneone uku taumaha), e kapi ana i ngā parau hurihuri whānui, ngā parau papa, me ngā parau whakairi kei te mākete. Ka whakamahia e ngā hua ngā kōhao tūnga pūtu paerewa mō te tāutanga ngāwari me te whakawhiti tere. Hei tāpiri, ka taea e mātou te whakarato i ngā otinga arotau piko ritenga i runga i te kaha o te tarakihana me te momo oneone e whakaratohia ana e te kiritaki.
