Me pēhea te whiriwhiri i tētahi taputapu whakamātautau pakeke mō te whakamātautau i ngā tauira ngongo?

1) Ka taea te whakamahi i te taputapu whakamātautau pakeke Rockwell hei whakamātautau i te pakeke o te pakitara paipa maitai?

Ko te rauemi whakamātautau he paipa maitai SA-213M T22, he 16mm te whānui o waho, ā, he 1.65mm te matotoru o te pakitara. Ko ngā hua whakamātautau o te whakamātautau pakeke Rockwell penei: Whai muri i te tango i te tauine waikura me te paparanga tango waro i runga i te mata o te tauira me te huri, ka whakatakotoria te tauira ki runga i te papa mahi āhua-V, ā, ka whakamahia te whakamātautau pakeke mamati Rockwell HRS-150S hei whakamātautau tika i te pakeke Rockwell i runga i tōna mata o waho me te kawenga 980.7N. Whai muri i te whakamātautau, ka kitea he iti te rerekētanga o te pakitara paipa maitai, ā, ko te mutunga iho he iti rawa te uara pakeke Rockwell i inehia, ka hua ake te whakamātautau kore mana.

E ai ki a GB/T 230.1-2018 «Whakamātautau Pakari o ngā Rauemi Whakarewa Rockwell Wāhanga 1: Tikanga Whakamātautau», ko te pakeke o Rockwell he 80HRBW, ā, ko te matotoru iti rawa o te tauira he 1.5mm. Ko te matotoru o te tauira Nama 1 he 1.65mm, ko te matotoru o te paparanga kua tangohia te waro he 0.15~0.20mm, ā, ko te matotoru o te tauira i muri i te tango i te paparanga kua tangohia te waro he 1.4~1.45mm, e tata ana ki te matotoru iti rawa o te tauira kua tohua i roto i te GB/T 230.1-2018. I te wā o te whakamātautau, nā te mea kāore he tautoko i waenganui o te tauira, ka puta he āhua rerekē iti (kāore pea e kitea e te kanohi tahanga), nō reira he iti te uara pakeke tuturu o Rockwell.

2) Me pēhea te whiriwhiri i te taputapu whakamātautau pakeke o te mata mō ngā paipa maitai:

I muri i ngā whakamātautau maha mō te pakeke o te mata o ngā paipa maitai, kua tae mai tā mātou kamupene ki ngā whakatau e whai ake nei:

1. Ina whakahaerehia te whakamātautau pakeke o te mata o Rockwell, te whakamātautau pakeke rānei o Rockwell i runga i te mata o ngā paipa maitai angiangi, ki te kore e ranea te tautoko o te pakitara o te paipa ka rerekē te āhua o te tauira, ā, ka iti ake ngā hua o te whakamātautau;

2. Ki te tāpirihia he tautoko porotaka ki waenganui o tētahi paipa maitai angiangi, ka iti ngā hua o te whakamātautau nā te mea kāore e taea te whakarite kia poutū te tuaka o te pane pēhanga me te ahunga o te kawenga kawenga ki te mata o te paipa maitai, ā, he āputa kei waenganui i te mata o waho o te paipa maitai me te tautoko porotaka kua whakauruhia.

3. He tino tika te tikanga mō te huri i te pakeke Vickers i inehia ki te pakeke Rockwell i muri i te whakairo me te whakakanapa i te tauira paipa maitai.

4. Whai muri i te tango i te unahi waikura me te paparanga tango waro i runga i te mata o te paipa maitai, me te miihini i te papa whakamātautau ki te mata o waho me te whakauru atu, ka hurihia te pakeke o te mata o Rockwell ki te pakeke o Rockwell, he mea tino tika.
