Ngā Taputapu Mīhini Ahuwhenua – He Ārai-Kakahu Kaha-Teitei Whakaahua Matua

Ngā Taputapu Mīhini Ahuwhenua – Te Upoko Parai Ātete-Kakahu Kaha-Teitei

Whakaahuatanga Poto:

Ngā Rauemi Kua Tīpakohia: Te whakamahi i te maitai hanganga waro-teitei, iti-koranu rānei, te maitai konupora 65Mn kounga teitei kei roto ko te boron, te konupora, me ētahi atu huānga koranu. Mā te tāpiri i ngā huānga koranu iti nei ka tino whakarei ake i te pakari me te pakari o te rauemi.

Maimoatanga Wera Matatau: Mā te whakamahana whānui, te tinei hinu, me te whakamahana pāmahana-waenga, ka puta he hanganga martensitic kua whakamahanahia kia ōrite, kia pai hoki. Ka whakarei ake i te mata tapahi mā te tinei auau-teitei ā-rohe, ka hangaia he pikinga mahi "mārō ki waho, mārō ki roto": ka eke te mārō o te mata ki te HRC 48-55, ko te matua ia e mau tonu ana te pakari o te pānga.

Tukanga Whakapakari: Ko ētahi tauira papai e whakamahi ana i ngā tokotoko whakarewa ātete-kakahu, i te rehu plasma rānei hei whakatakoto i tētahi paparanga koranu mārō tungsten carbide ki runga i te mata pa, ka hanga he mata ātete-kakahu matotoru, ka roa ake te ora ratonga mā te 2-3 ngā wā ki te whakataurite ki ngā pito o te hea parau noa.

Koki Tomokanga Whakangawari: Mā te koki tomo 25°-30° i arotauhia mō ngā nekehanga oneone ka whakarite kia whakakoi-ā-ia anō te mahi, ka whakaiti i te ātete ki te kume mā te 15%-20% me te whakaiti i te whakapaunga wahie.

Ngā Ripe Whakakaha me te Hanganga Tūnga: Mā ngā ripe whakakaha trapezoidal i te tuara ka ārai i te piko me te rerekētanga i raro i ngā kawenga nui; he mea mira tika ngā mata whakairi pūtu mō te tūnga tika me te whakamau pono, ka ārai i te wetewete me te whati.

Atanga Paerewa: E rite ana ki te ISO me ngā rahinga tāutanga tinana parau ā-whare matua, e āhei ai te whakakapinga tere kore-taputapu.

He mea hanga motuhake tēnei hua mō te mahi ahuwhenua o ēnei rā. Hei wāhanga matua, he wāhanga ngāwari te pakaru, e pā tika ana ki te oneone, ā, e tu atu ana i te waku me te pānga nui rawa atu, he mea hanga te pito parau mai i te maitai koranu kounga teitei. He pai mō te whakamahi me ngā taputapu mahi whenua maha pērā i ngā parau papa pokepoke, ngā parau hurihuri, me ngā parau waikeri, ā, he wāhanga matua āwhina mō te whakapai ake i te pai o te mahi a te mīhini, te whakaiti i te whakapaunga pūngao, me te whakarite i te kounga o te mahi whenua.

He rerekē ki ngā whakarewa noa, ka whakamahia e mātou te hanga tika hei whakakore i te porowhita o roto me ngā kōhao onepu, ka whakapai ake i te mātotoru me te pakari o te pānga. He mea hanga pūtaiao te maitai me ngā huānga chromium (Cr) me te boron (B), ā, ka tukuna he maimoatanga wera tuarua ki ngā mata mahi matua. Mā tēnei ka whakarite kia 48-52 HRC te pakeke o te mata, me te pupuri tonu i te ngāwari o te matua, ka ārai i te pakaru o te tūtaki ki ngā toka, ki ngā pakiaka rākau rānei i te wā e whakamahia ana.

Tino ātete ki te kakahu: Mā te paninga tungsten carbide matotoru, mā te hangarau koranu mārō kua whakakikoruatia rānei, ka roa ake te ora o te mahi i roto i ngā oneone uaua pēnei i te onepu me te kirikiri. E whakaatu ana ngā inenga tuturu i te roanga o te ora e 3-5 ngā wā i te roanga o ngā hea parau rino noa.

Te werohanga koi o te oneone: Mā te whakamahi i tētahi hoahoa mata piko kua whakaritea, kua whakaitihia te piri o te oneone me te ātete haere, ka heke te whakapaunga wahie o te tarakihana tata ki te 8%-12%.

Te whakakoi haumaru i a ia anō: Mā te hoahoa hanganga motuhake ka taea e te pito parau te pupuri i te mata koi i te wā e pakaru ana, ka karohia ngā raruraru pēnei i te parautanga kāore i oti me te hipoki kāore i te tika nā te pirau.
