Nga korero: Mo te tapahi tapahi, ka taea te huri kia rite ki te 1HRC≈10HB (he awhe rerekee te pakeke o te papanga mahi)
Te pakeke o nga mea whakarewa
Ko te pakeke e tohu ana ki te kaha o tetahi mea ki te aukati i nga huringa o te rohe, ina koa ko te rerekee o te kirihou, te nuku, te rakuraku ranei.He tohu tohu hei ine i te ngawari me te pakeke o te papanga.
E ai ki nga tikanga whakamatautau rereke, ka wehewehea te pakeke ki nga momo e toru.
①Te pakeke o te karawarawa.Ka whakamahia te nuinga ki te whakataurite i te ngawari me te pakeke o nga kohuke rereke.Ko te tikanga ko te whiriwhiri i te rakau me tetahi pito ka pakeke me tetahi pito he ngohengohe, ka tukuna nga mea hei whakamatautau i te taha o te rakau, me te whakatau i te pakeke o nga mea hei whakamatautau i runga i te waahi o te pakaru.I runga i te kounga, ko nga mea pakeke ka hanga i nga rakuraku roa me nga mea ngawari ka hanga poto.
②Te pakeke nuku.Ko te nuinga o te whakamahi mo nga taonga whakarewa, ko te tikanga ko te whakamahi i tetahi kawenga ki te pehi i te indenter kua tohua ki roto i nga mea hei whakamatautau, me te whakataurite i te ngawari me te pakeke o nga mea ka whakamatauhia e te rahi o te huringa kirihou o te rohe i runga i te mata o te rauemi.Na te rereketanga o te indenter, te kawenga me te roanga o te kawenga, he maha nga momo o te pakeke nuku, te nuinga tae atu ki te Brinell pakeke, Rockwell pakeke, Vickers pakeke me te microhardness.
③Rebound pakeke.Ko te nuinga o nga mea e whakamahia ana mo nga mea whakarewa, ko te tikanga ko te hanga i tetahi hama iti motuhake kia taka noa mai i tetahi teitei ki te pa ki te tauira o nga mea hei whakamatautau, me te whakamahi i te nui o te kaha riaka kua penapena (ka tukuna) i roto i te tauira i te wa o te te awenga (ma te hokinga mai o te hama iti) ine teitei peke) hei whakatau i te pakeke o te rawa.
Ko te pakeke Brinell tino noa, Rockwell pakeke me Vickers pakeke o nga rauemi whakarewa no te pakeke indentation.Ko te uara pakeke e tohu ana i te kaha o te mata o te papanga ki te aukati i te huringa kirihou na tetahi atu mea e pehia ana ki roto;C) ki te ine i te pakeke, a ko te uara pakeke e tohu ana i te rahi o te mahi rerekee elastic o te whakarewa.
Brinell pakeke
Whakamahia he poi rino kua tineia, he poi koranu maro ranei me te diameter o D hei indent, pehia ki te mata o te waahanga whakamatautau me te kaha whakamatautau F e rite ana, a, i muri i te waa pupuri, tangohia te kaha whakamatautau kia whiwhi nuku he diameter o d.Wehea te kaha whakamatautau ki te mata o te nuku, a ko te uara ka puta ko te uara pakeke Brinell, a ko te tohu e tohuhia ana e HBS, HBW ranei.
Ko te rereketanga i waenga i te HBS me te HBW ko te rereketanga o te indenter.Ko te tikanga o te HBS ko te indentor he poi rino whakapakeke, ka whakamahia hei ine i nga rawa me te uara pakeke Brinell i raro i te 450, penei i te rino ngawari, te rino hina me nga konganuku kore-ferrous.Ko te tikanga o te HBW he carbide cimented te indenter, ka whakamahia hei ine i nga rawa me te uara pakeke Brinell kei raro i te 650.
Mo te poraka whakamatautau ano, ina he rite tonu etahi atu tikanga whakamatautau, he rereke nga hua o nga whakamatautau e rua, a ko te uara HBW he nui ake i te uara HBS, kaore he ture ine hei whai.
Whai muri i te tau 2003, kua rite i taku whenua te tango i nga paerewa o te ao, kua whakakorehia nga whakaurunga poi rino, me nga upoko poi carbide katoa.Na reira, ka mutu te HBS, ka whakamahia te HBW hei tohu i te tohu pakeke Brinell.I te nuinga o nga wa, ko te pakeke Brinell e whakaatuhia ana i roto i te HB, e tohu ana ki te HBW.Heoi, ka kitea tonutia a HBS i ia wa i ia wa i roto i nga pepa tuhinga.
Ko te tikanga ine pakeke Brinell he pai mo te rino maka, koranu kore-ferrous, he momo rino kua rerihia me te tineia, e kore e pai mo te whakamatautau tauira,nga waahanga hurihuri cnche pakeke rawa, he iti rawa, he angiangi rawa, kaore ranei e tuku i nga nuku nui ki te mata.
Rockwell Hardness
Whakamahia he koeko taimana 120°, Ø1.588mm ranei, me te Ø3.176mm nga poi tira tinei hei indenter me te uta ki te mahi tahi.Ko te kawenga tuatahi ko te 10kgf me te tapeke kawenga he 60, 100, 150kgf ranei (ara, te uta tuatahi me te uta matua).Ko te pakeke e whakaatuhia ana e te rereketanga i waenga i te hohonu o te whakauru i te wa e tangohia ai te kawenga matua me te hohonu o te whakauru i te wa e mau tonu ana te kawenga matua me te hohonu o te whakauru i raro i te kawenga tuatahi i muri i te whakamahinga o te kawenga katoa.
Ka whakamahia e te whakamatautau pakeke Rockwell e toru nga kaha whakamatautau me nga nuku e toru.E 9 nga huinga o aua mea, e rite ana ki nga unahi e 9 o te pakeke o Rockwell.Ko te tono o enei rangatira e 9 ka hipokina te nuinga o nga taonga whakarewa e whakamahia ana.E toru nga HRA e whakamahia nuitia ana, HRB me HRC, kei roto ko te HRC te nuinga o te whakamahi.
Ka whakamahia noa te ripanga tohu whakamatautau whakamaroke Rockwell:
| Te pakeke | | | Te pakeke | |
| | | | | Karaka, karaka, |
| | | | | He rino, he maitai kua whakaritea, he konumohe konumohe |
| | | | | te rino whakapakeke, te rino kua tineia me te whakamahana, te hohonu |
Ko te awhe o te whakamahi i te tauine HRC ko 20~70HRC.A, no te he iti iho i te 20HRC te uara pakeke, no te mea te koekokonumohe cnc machining wahio te indenter ka pehia rawatia, ka heke te tairongo, me te whakamahi i te tauine HRB;ka nui ake te pakeke o te tauira i te 67HRC, he nui rawa te pehanga i runga i te pito o te indenter, ka ngawari te pakaru o te taimana.Ka tino poroa te ora o te indenter, no reira me whakamahi te tauine HRA.
He ngawari, he tere, he iti te nuku o te whakamatautau pakeke o Rockwell, ka taea te whakamatautau i te mata o nga hua kua oti me nga taputapu mahi uaua me te kikokore.Na te iti o te nuku, mo nga rawa he koretake te hanganga me te pakeke, ka rere ke te uara pakeke, karekau te tika e rite ki te pakeke o Brinell.Ka whakamahia te pakeke Rockwell ki te whakatau i te pakeke o te rino, nga konganuku kore-ferrous, nga koranu maro, me era atu.
Vickers pakeke Vickers pakeke
He rite te kaupapa o te ine pakeke o Vickers ki tera o te pakeke o Brinell.Whakamahia he taimana tapawha koeko indenter me te koki whakauru o 136° ki te pēhi ki te mata o te rauemi ki te kaha whakamātautau tohua F, ka tango i te kaha whakamātautau i muri i te pupuri i te wa i tohua.Ko te pakeke e whakaatuhia ana e te pehanga toharite o te waahanga mata o te nuku tara tapawha.Uara, ko te tohu tohu ko te HV.
