He mea tino nui te whakamātautau i te pakeke o te topenga mahi punga. Me tino pakari te topenga i te wā e whakamahia ana kia pono ai, kia roa ai hoki tana mahi. Ka taea e te Kamupene Laihua te whakarite i ngā momo rawhi motuhake kia rite ki ngā hiahia, ā, ka taea hoki te whakamahi i te taputapu whakamātautau pakeke a Laihua hei whakamātautau i te pakeke.
Ko te paerewa whakamātautau pakeke o te topenga punga e pā ana ki:
1. Te pakeke o Rockwell GB/T 230.1-2018
E whakamahia ana e tēnei paerewa te tikanga whakamātautau pakeke o Rockwell me te tauine pakeke HRC Rockwell mō te whakamātautau. He māmā noa te whakahaere i tēnei tikanga whakamātautau, ā, koinei te whiringa pai rawa atu mō ngā kiritaki.
2. Te pakeketanga o Brinell GB/T231.1-2018.
Ka whakamahia e tēnei paerewa te tauine pakeke Brinell HB mō te whakamātautau.
Ko te paerewa aromatawai e pā ana ki:
GB/T 14370-2015, JT/T 329-2010 rānei.
Nā te āhua motuhake o te topenga punga, kia rite ki te rahi o te topenga me te rahi o te diameter o roto o te topenga a te kiritaki, i te hoko i tētahi taputapu whakamātautau pakeke, me whakarite kia rite ki te hiahia o ngā taputapu ngaio kia tika ai te ine me te roa ake o te ora o te taputapu whakamātautau pakeke. Mēnā e tika ana, tēnā koa tukuna mai he tauira mā te mēra hei whakamātautau.
Tikanga mō te whakamātautau i te pakari o te pakaru o ngā taputapu karāhe sima mā te pakeke o Vickers (whakamahia te whakamātautau pakeke o Vickers):
Ko te tikanga, me whakamātautau te pakeke o te kāpira sima mā te whakamahi i te tauine pakeke A a Rockwell. Mēnā he iti iho i te 1.6 mm te matotoru o te mea mahi, o te tauira rānei, ka taea te whakamahi i te tikanga pakeke a Vickers hei whakamātautau. Nā, he aha te tikanga hei whakamātautau i te pakari o te pakaru o ngā taputapu kāpira sima?
Paerewa whakamātautau pakari whati me te paerewa whakatinanatanga tikanga whakamātautau pakari whati mō ngā rauemi turanga taputapu karāhe sima: JB/T 12616—2016;
Ko te tikanga whakamātautau e whai ake nei:
Tuatahi, hangaia te mea mahi hei whakamātautau hei tauira, kātahi ka whakakanapahia te mata o te tauira hei mata whakaata, ka whakanoho ki raro i te taputapu whakamātautau pakeke moroiti hei whakaputa i te kōhao ki runga i te mata kua whakakanapahia me te kōhao taimana kōniko o te taputapu whakamātautau pakeke, kia puta ai ngā kapiti kua oti te hanga i ngā pito e whā o te kōhao.
Ka tatauhia te uara pakari whati (KIC) i runga i te kawenga kōpiko P me te roa toronga o te pakaru kōpiko C.
Kei te wātea tonu te wheketere taputapu whakamātautau o Laizhou Laihua ki te whakautu i ō pātai katoa.
