Te Pūwāhi Tiritiri Parāoa Tarakihana Ahuwhenua / Te Mata o te Parāoa – Ngā Wāhanga Whakamau Rino Pakari mō te Parāoa Kōpae
Ko tēnei pito o te parau, he wāhanga matua, he wāhanga ngāwari hoki te pakaru o ngā mīhini parau ahuwhenua, he mea hanga motuhake mō te whakamahi me ngā momo parau papa pokepoke, ngā parau hurihuri, me ngā parau waikeri. Kei te taha mua rawa o te tinana parau, koia te wāhanga tuatahi ka pā ki te oneone, ka tapahia ngā poraka, ā, ka mau i te waku me te pānga nui rawa atu. Ko tōna kounga te mea e whakatau tika ana i te pai o te parau, te whakapaunga pūngao, me te roanga o te ora o te tinana parau.
1, Ngā Rauemi Kua Tīpakohia: Ka whakamahia te maitai hanganga waro-teitei, te maitai konupora kounga teitei rānei, he boron, he konupora, me ētahi atu huānga whakakoi. Mā te tāpiri i ngā huānga whakakoi iti nei ka tino whakapai ake i te pakari me te pakari o te rauemi.
2、Maimoatanga Wera Matatau: Ka whakamahanahia te rauemi katoa, ka tineihia te hinu, ka whakamahanahia hoki i te pāmahana waenga kia whiwhi ai i te hanganga martensitic kua whakamahanahia kia ōrite, kia pai hoki. Ka whakareihia ake te mata tapahi mā te tinei auau-teitei ā-rohe, ka hanga he pikinga mahi "mārō i waho, mārō i roto": ka eke te mārō o te mata ki te HRC 48-55, ko te matua ia ka mau tonu te pakari o te pānga.
3, Tukanga whakarei ake: Ko ētahi tauira papai e whakamahi ana i ngā tokotoko whakarewa ātete-kakahu hei hanga, hei rehu rānei i te paparanga koranu mārō tungsten carbide ki runga i te mata oneone e pa ana, ka hanga he whatunga ātete-kakahu matotoru, ka whakanui ake i te roa o te mahi mā te 2-3 ngā wā ki te whakataurite ki ngā pito parau noa.
Koki whakaurunga māmā: Mā te koki whakaurunga 25°-30° i arotauhia i runga i te kaha o te oneone ka whakarite kia taea te whakakoi i a ia anō, ka whakaiti i te ātete ki te kume mā te 15%-20%, ā, ka whakaiti i te whakapaunga wahie.
Ngā rara whakapakari me te hanganga tūnga: Kua tāutahia ngā rara whakapakari trapezoidal ki te tuara hei 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, te whakamau pono, me te ārai i te wetekina me te whati.
Te ātete ki te kakahu: He pakari te mata, he pakari te papa, e mau tonu ana te koi o te mata ahakoa i roto i ngā āhuatanga kino pēnei i te oneone onepu me te oneone kirikiri, e taea ai e te waeine kotahi te kapi i te rohe 200-300 eka.
Ātete pānga nui: Ka taea te tu atu i ngā pānga kino mai i ngā mea mārō pēnei i ngā toka me ngā pakiaka rākau, me te kore e whati, e pakaru rānei.
He pai te whai huatanga o te ōhanga: He iti te utu mō ia wae, ā, mā te whakaroa i te huringa whakakapinga me te whakaiti i te wā kore mahi, ka whakaitihia ngā utu ahuwhenua whānui mā te 10%-15%.
