He mea tino nui ki te whakamatautau i te pakeke o te topenga mahi punga. Me tino pakeke te topenga i te wa e whakamahia ana hei whakarite i te pono me te mauroa o tana mahi. Ka taea e te Kamupene Laihua te whakarite i nga momo rawhi motuhake kia rite ki nga hiahia, ka taea hoki te whakamahi i te whakamatautau pakeke a Laihua mo te whakamatautau pakeke.
Ko te paerewa whakamatautau pakeke o te topenga punga e pa ana ki:
1. Rockwell pakeke GB/T 230.1-2018
Ka whakamahia e tenei paerewa te tikanga whakamatautau pakeke a Rockwell me te tauine pakeke HRC Rockwell mo te whakamatautau, Ko tenei tikanga whakamatautau he ngawari ki te whakahaere me te mea tino pai mo nga kaihoko.
2. Brinell pakeke GB / T231.1-2018.
Ka whakamahia e tenei paerewa te tauine HB pakeke Brinell mo te whakamatautau.
Ko te paerewa aro mātai e pā ana ki:
GB / T 14370-2015 ranei JT / T 329-2010.
Na te mea motuhake o te ahua o te topenga punga, kia rite ki te rahi o te topenga a te kaihoko me te rahi o te rahi o roto, i te wa e hoko ana i te whakamaarama pakeke, he mea tika ki te whakarite i nga taputapu ngaio e hiahiatia ana hei whakarite i te tika o te uara ine me te whakawhānui. te oranga o te mahi whakamatautau pakeke. Mena e tika ana, tena koa tukuna mai nga tauira mo te whakamatautau.
Tikanga mo te whakamatautau i te pakari whati o nga taputapu carbide cimented na te pakeke o Vickers (whakamahia Vickers pakeke tester):
Ko te pakeke o te carbide cimented me whakamatau ma te whakamahi i te Rockwell hardness A scale. Mena he iti iho te matotoru o te taputapu mahi, tauira ranei i te 1.6 mm, ka taea te whakamahi i te tikanga pakeke Vickers mo te whakamatautau. Na he aha te tikanga mo te whakamatautau i te pakari pakaru o nga taputapu carbide cimented?
Ko te paerewa whakamatautau mo te kaha o te pakaru me te tikanga mo te whakatinana i te tikanga whakamatautau mo nga taputapu turanga taputapu carbide cimented: JB/T 12616—2016;
Ko te tikanga whakamatautau e whai ake nei:
Tuatahi, mahia te mea mahi kia whakamatauria hei tauira, katahi ka whakakorikoria te mata o te tauira ki te mata whakaata, ka waiho ki raro i te microhardness tester hei whakaputa i te nuku ki runga i te mata kua orohia me te nuku taimana koeko o te whakamatautau pakeke, na. ko nga kapiti kua oti te hanga i nga pito e wha o te nuku.
Ko te uara pakari whati (KIC) ka tatauhia i runga i te kawenga nuku P me te roa toronga kapiti C.
Kei te waatea tonu a Laizhou Laihua Testing Instrument Factory ki te whakautu i nga patai kei a koe.
