Ngā taputapuka whakawhirinaki ki ō rātou ake hanganga me te kaha o ngā rauemi hei tu atu i ngā kawenga o waho, e hiahia ana kia nui te kaha, te pakari me te ātete ki te kakahu o ngā rauemi; nā te āhua uaua o ngā taputapu, ko tengā taputapume tino tika te hanga, ā, me pai hoki te hanga o ngā rauemi. Ko ngā rauemi e whakamahia whānuitia ana ko te maitai whakarewa, te maitai whakarewa, me te rino whakarewa.
1. Rino whakarewa E ai ki te pakeke o te mata o te niho, ka wehea kia rua ngā wāhanga:
Ina HB <350, ka kiia ko te mata niho ngohengohe
Ina HB ≥350, ka kiia he mata niho mārō.
1.1. Te pakeke o te mata o ngā niho HB <350
Tukanga: hanga pātea → whakataurite - hurihanga taratara → tinei me te whakamahana, whakaotinga
Ngā rauemi e whakamahia whānuitia ana; 45#, 35SiMn, 40Cr, 40CrNi, 40MnB
Ngā Āhuatanga: He pai te mahi whānui, he kaha, he mārō hoki te mata o te niho, ā, he pakari te ngākau o te niho. I muri i te maimoatanga wera, ka tino tika teNgā taputapuKa taea e te tapahi te eke ki te 8 ngā taumata. He ngāwari te hanga, he iti te utu, ā, he nui te hua. Kāore i te tino tika.
1.2 Te pakeke o te mata o te niho HB ＞350
1.2.1 Ina whakamahia te maitai waro waenga:
Tukanga: Te hanga i te mea parakore → te whakataurite → te tapahi taratara → te tinei me te whakamahana → te tapahi pai → te tinei auau teitei me te waenga → te whakamahana pāmahana iti → te whakakoi, te oma whakakoi rānei, te oma hiko hiko.
Ngā rauemi e whakamahia whānuitia ana:45, 40Cr, 40CrNi
Ngā Āhuatanga: He teitei te pakeke o te mata o te niho, HRC=48-55, he teitei te kaha o te pa, ā, he pai te ātete ki te kakahu. Ka mau tonu te pakari o te matua o te niho i muri i te tinei me te whakamahana, he pai te ātete pānga me te kaha ki te kawe kawenga. Ka heke te tika ki te haurua, tae atu ki te taumata 7 o te tika. He pai mō te hanga papatipu, pērā i ngā taputapu tuku tere-waenga me te kawenga-waenga mō ngā motuka, ngā taputapu mīhini, me ētahi atu.
1.2.2 Ina whakamahia te maitai waro iti: Te hanga i te maitai parakore → te whakataurite → te tapahi taratara → te tinei me te whakamahana → te tapahi pai → te whakamahana me te tinei → te whakamahana pāmahana iti → te huri niho. Tae atu ki te 6 me te 7 ngā taumata.
Ngā rauemi e whakamahia whānuitia ana; 20Cr, 20CrMnTi, 20MnB, 20CrMnTo Ngā Āhuatanga: He pakari te mata o ngā niho, he kaha hoki te kawe. He pakari te uho, ā, he ātete ki te pānga. He pai mō te tuku tere-nui, taumaha-kawenga, taumaha-kaha rānei, mō ngā wā rānei e hiahiatia ana he hanganga kiato, hei taputapu tuku matua mō ngā waka tereina me ngā taputapu rererangi.
2. Rino whakarewa:
Ina tetaputapuKo te diameter d>400mm, he uaua te hanganga, ā, he uaua te hanga, ka taea te whakamahi i te rauemi maitai whakarewa ZG45.ZG55 hei whakataurite. Te whakataurite, te tinei me te whakamahana.
3. Rino maka:
He kaha te ātete ki te piri me te waikura o te rua, engari he ngoikore te ātete ki te pānga me te karawarawa. He pai mō te mahi pumau, te kaha iti, te tere iti, te rahi nui me te āhua uaua. Ka taea te mahi i raro i ngā āhuatanga kore hinu, ā, he pai mō te tuku tuwhera.
4. Rauemi whakarewa:
He papanga, he rakau, he kirihou, he nairona, e tika ana mō te tere tiketike me te kawenga māmā.
I te wā e whiriwhiri ana i ngā rauemi, me whai whakaaro ki te meka he rerekē ngā tikanga mahi o ngā taputapu, me ngā momo pakaru o ngā niho taputapu, koinei te pūtake mō te whakatau i ngā paearu tatau kaha o te taputapu me te whiriwhiri i ngā rauemi me ngā wāhi wera.
1. Ina ngāwari te whati o ngā niho taputapu i raro i te kawenga pānga, me whiriwhiri ngā rauemi he pakari ake, ā, ka taea te whiriwhiri i te maitai waro iti mō te whakakā me te tinei.
2. Mō te tuku tere-nui, he ngāwari te mata o te niho ki te pakaru, nō reira me whiriwhiri ngā rauemi he pai ake te pakeke o te mata o te niho, ā, ka taea te whakamahi i te whakapakeke mata o te maitai waro-waenga.
3. Mō te tere iti me te kawenga waenga, ina pakaru, ka pakaru, ka pakū te niho taputapu, me whiriwhiri ngā rauemi he kaha miihini pai, he pakeke te mata o te niho me ētahi atu āhuatanga miihini whānui, ā, ka taea te whiriwhiri i te maitai waro-waenga kua tineihia, kua whakamahanahia.
4. Kia iti te whānuitanga o ngā rauemi, kia ngāwari te whakahaere, ā, kia whakaarohia hoki ngā rauemi me te whakarato.
5. Mēnā he iti te rahi o te hanganga, ā, he teitei te ātete ki te kakahu, me whakamahi te maitai koranu.
6. Ngā taputapu me ngā hangarau o te wāhanga hanga.
