Iyo Vickers kuomarara tester inotora dhaimondi indenter, iyo inotsikirirwa mukati meiyo sampuli pasi peimwe simba rekuyedza. Bvisa simba rekuyedza mushure mekuchengetedza nguva yakatarwa uye kuyera iyo diagonal kureba kweiyo indentation, ipapo Vickers kuomarara kukosha (HV) inoverengerwa zvinoenderana neformula.
Mhedzisiro yemusoro kudzvanya pasi
-Kushandisa simba rekuyedza: Musoro wekudzvanya pasi danho idanho rakakosha kuendesa seti yekuyedza simba (se1kgf, 10kgf, zvichingodaro) kusvika pamusoro pezvinhu zvakaedzwa kuburikidza neindenter.
- Kugadzira indentation: Dzvinyiriro inoita kuti indenter isiye yakajeka dhaimondi indentation pamusoro pezvinhu, uye kuomarara kunoverengerwa nekuyera kureba kwediagonal kweiyo indentation.
Kuvhiya uku kunoshandiswa zvakanyanya mukuomarara kuyedza zvinhu zvesimbi, mashizha matete, machira, nezvimwewo, nekuti ine yakakura bvunzo simba renji uye diki indentation, inokodzera kuyerwa chaiko.
Seyakajairwa dhizaini yeVickers hardness tester (yakasiyana nemhando yebhenji inosimuka), zvakanakira "kutsikirira musoro pasi" ndiko kurongeka kwemaitiro ekushanda uye mekiniki chimiro, zvinyorwa sezvinotevera,
1. Kunyanya kushanda kuri nyore, kuenderana nemaitiro emunhu-muchina
Mumusoro uchitsikirira pasi dhizaini, mushandisi anogona kuisa zvakananga sampu pane yakagadziriswa workbench, uye kupedzisa kubata uye kurodha yeindenter nemusoro zvichidzika, pasina kazhinji kugadzirisa urefu hwebhenji rebasa. Iyi "yepamusoro-pasi" maitiro ekushanda akakodzera kune akajairwa maitiro ekushanda, kunyanya hushamwari kune vatsva, inogona kuderedza nhanho dzinonetesa dzekuisa sampuli uye kurongeka, kuderedza zvikanganiso zvekushanda kwevanhu.
2. Yakasimba kurodha kugadzikana, yakakwirira kuyerwa kurongeka
Musoro wekudzvanya pasi chimiro unowanzo tora yakaomesesa yekurodha meshini (yakaita seyakanyatso screw rods uye gwara rekutungamira). Paunenge uchishandisa simba rekuyedza, iyo verticality uye kurodha kumhanya kweiyo indenter zviri nyore kudzora, izvo zvinogona kunyatso kudzikisa mechini vibration kana kumisa. Kune zvinhu chaizvo zvakaita semashiti matete, machira, uye zvikamu zvidiki, kugadzikana uku kunogona kudzivirira deformation ye indentation inokonzerwa nekusagadzikana kurodha uye zvakanyanya kunatsiridza kuyerwa kwechiyero.
3. Wider adaptability yemasampuli
Kune sampuli dzehukuru hukuru, humiro husina kukwana kana huremu hunorema, musoro-pasi dhizaini haidi kuti bhenji rebasa ritakure mutoro wakawandisa kana kureba zvirambidzo (bhenji rekushanda rinogona kugadziriswa), uye rinongoda kuve nechokwadi chekuti sampuli inogona kuiswa pane yebasa, iyo inonyanya "kushivirira" kune sampuli. Rising workbench dhizaini inogona kuganhurirwa nekutakura-kusimudza uye kusimudza sitiroko yebhenji rebasa, saka zvakaoma kuchinjika kune yakakura kana inorema samples.
4. Zvirinani kuyerwa kudzokororwa
Iyo yakagadzika yekurodha nzira uye yakanakira mashandiro ekuita inogona kuderedza kukanganisa kunokonzerwa nekusiyana kwekushanda kwevanhu (sekutsauka kwekugadzirisa kana bhenji rebasa rinosimudza). Pakuyera sampuli imwechete kakawanda, iyo yekusangana mamiriro pakati peindenter nemasamples inowirirana, iyo data kudzokorora kuri nani, uye kuvimbika kwemhedzisiro kwakakwira.
Mukupedzisa, iyo-pasi-pasi Vickers kuomarara tester ine zvimwe zvakanakira mukuita nyore, kugadzikana, uye kuchinjika nekugadzirisa maitiro ekushanda uye magadzirirwo emuchina, uye anonyanya kukodzera kuyedzwa kwezvinhu, akawanda-mhando sampuli kuyedzwa kana yakakwirira-frequency yekuyedza mamiriro.
