E rua ngā wāhanga o te maimoatanga wera o te mata: ko te maimoatanga wera o te tinei o te mata me te whakamahana i te whakamahana, ā, ko te maimoatanga wera matū tētahi. Ko te tikanga whakamātautau pakeke e whai ake nei:
1. te tinei me te whakamahana i te maimoatanga wera
Ko te whakamahana i te tineitanga o waho me te whakamahana i te wera ka mahia mā te whakamahana arataki, te whakamahana mura rānei. Ko ngā tawhā hangarau matua ko te pakeketanga o waho, te pakeketanga o te rohe me te hohonutanga o te paparanga whakapakeke whai hua. Ka taea te whakamahi i te whakamātautau pakeketanga Vickers, te whakamātautau pakeketanga Rockwell rānei mō te whakamātautau pakeketanga. Te kaha whakamātautau E pā ana te kōwhiringa ki te hohonutanga o te paparanga whakapakeke whai hua me te pakeketanga o waho o te mea mahi. E toru ngā mīhini pakeketanga e whai wāhi ana ki konei.
(1) He mea nui te whakamātautau pakeke Vickers hei whakamātautau i te pakeke o waho o ngā mea mahi i whakamahanatia. Ka taea e ia te whakamahi i te kaha whakamātautau o te 0.5-100KG hei whakamātautau i te paparanga whakapakeke o waho he angiangi ki te 0.05mm te matotoru. He teitei tōna tika, ā, ka taea e ia te wehewehe i ngā mea mahi i whakamahanatia. Ko te rerekētanga iti o te pakeke o waho, hei tāpiri, ko te hohonu o te paparanga whakapakeke whai hua ka kitea hoki e te whakamātautau pakeke Vickers, nō reira me whakarite he whakamātautau pakeke Vickers mō ngā waeine e whakahaere ana i te tukatuka maimoatanga wera o waho, e whakamahi ana rānei i te maha o ngā mea mahi maimoatanga wera o waho.
(2) He tino pai hoki te whakamātautau pakeke o te papa o Rockwell mō te whakamātautau i te pakeke o te mea mahi kua tineihia. E toru ngā tauine mō te whakamātautau pakeke o te papa o Rockwell hei whiriwhiri māu. Ka taea e ia te whakamātautau i ngā momo mea mahi kua whakapakeketia, he hohonu ake te paparanga whakapakeketia i te 0.1mm. Ahakoa kāore te tika o te whakamātautau pakeke o te papa o Rockwell i te teitei pērā i te whakamātautau pakeke o Vickers, ka taea e ia te whakatutuki i ngā whakaritenga hei tikanga kimi mō te whakahaere kounga me te tirotiro tohu o ngā tipu maimoatanga wera. Haunga tēnā, he ngāwari te whakahaere, he watea te whakamahi, he iti te utu, he tere te ine, me te pānui tika i ngā uara pakeke. Ka taea te whakamahi i te whakamātautau pakeke o te papa o Rockwell hei kimi tere me te kore e whakangaro i ngā puranga o ngā mea mahi kua tukatukahia kia werahia, takitahi. He mea nui ki ngā wheketere tukatuka whakarewa me te hanga mīhini. Ina matotoru te paparanga whakapakeketia, ka taea hoki te whakamahi i te whakamātautau pakeke o Rockwell. Ina 0.4-0.8mm te matotoru o te paparanga maimoatanga wera, ka taea te whakamahi i te tauine HRA. Ina nui ake te hōhonutanga o te paparanga whakapakeke i te 0.8mm, ka taea te whakamahi i te tauine HRC. Ka taea te huri ngāwari i ngā uara paerewa pakeke e toru o Vickers, Rockwell me Rockwell papatahi ki a rātou anō, ka hurihia hei paerewa, hei tuhi, hei uara pakeke rānei e hiahiatia ana e ngā kaiwhakamahi, ā, ko te ripanga tahuritanga e rite ana kei roto i te paerewa o te ao ISO. Kua hoatu te paerewa o Amerika ASTM me te paerewa Hainamana GB/T.
(3) Ina neke atu i te 0.2mm te matotoru o te paparanga whakapakeke kua whakamahanatia, ka taea te whakamahi i te taputapu whakamātautau pakeke Leeb, engari me whiriwhiri he pūoko momo-C. I te wā e ine ana, me aro ki te āhua o waho me te matotoru whānui o te mea mahi. Kāore i te tika te taputapu whakamātautau pakeke Vickers me Rockwell i tēnei tikanga ine, engari he pai mō te ine i te wāhi mahi i roto i te wheketere.
2 maimoatanga wera matū
Ko te maimoatanga wera matū he whakauru i ngā ngota o tētahi, ētahi rānei o ngā huānga matū ki roto i te mata o te mea mahi, ā, ka huri te hanganga matū, te hanganga me te mahi o te mata o te mea mahi. Whai muri i te tinei me te whakamahana i te pāmahana iti, ka pakeke te mata o te mea mahi, ā, ka ātete ki te kakahu, ka kaha te ngenge pa, ā, he kaha, he pakari hoki te uho o te mea mahi. Ko ngā tawhā hangarau matua o te mea mahi maimoatanga wera matū ko te hohonutanga o te paparanga whakapakeke me te pakeketanga o te mata. Ko te tawhiti e heke ai te pakeketanga ki te 50HRC ko te hohonutanga o te paparanga whakapakeke whai hua. He rite te whakamātautau pakeketanga o ngā mea mahi tukatuka wera matū ki te whakamātautau pakeketanga o ngā mea mahi tukatuka wera o te mata o te mea mahi. Ka taea te whakamahi i ngā whakamātautau pakeketanga Vickers, ngā whakamātautau pakeketanga Rockwell o te mata, ngā whakamātautau pakeketanga Rockwell rānei. Hei kite i te whakamātautau pakeketanga, ko te matotoru o te nitriding anake he angiangi ake, ko te tikanga kāore e neke atu i te 0.7mm, kātahi ka kore e taea te whakamahi i te whakamātautau pakeketanga Rockwell.
3. te maimoatanga wera ā-rohe
Mena he nui te pakeke o ngā wāhanga maimoatanga wera ā-rohe, ka taea te whakahaere i te maimoatanga wera tinei ā-rohe mā te whakamahana hiko, me ētahi atu. Me tohu te tūranga o te maimoatanga wera tinei ā-rohe me te uara pakeke ā-rohe o aua wāhanga ki te tuhi, ā, me whakahaere te whakamātautau pakeke o ngā wāhanga ki te wāhi kua tohua, ka taea e te taputapu whakamātautau pakeke te whakamahi i te whakamātautau pakeke Rockwell hei whakamātautau i te uara pakeke HRC. Mena he papaku te paparanga whakapakeke maimoatanga wera, ka taea te whakamahi i te whakamātautau pakeke Rockwell papatahi hei whakamātautau i te uara pakeke HRN.
