1 Ukulungiselela ngaphambi kokuhlolwa
1) Umhloli wokuqina kanye ne-indenter esetshenziselwa ukuhlola ubulukhuni be-Vickers kufanele ihambisane nezinhlinzeko ze-GB/T4340.2;
2) Izinga lokushisa lekamelo kufanele lilawuleke phakathi kwebanga lika-10 ~ 35℃. Ezivivinyweni ezinezidingo ezinembayo eziphezulu, kufanele zilawulwe kokuthi (23±5)℃.
2 amasampula
1) Indawo yesampula kufanele ibe isicaba futhi ibushelelezi. Kutuswa ukuthi isampula lendawo elukhuni kufanele ihlangabezane nezidingo: Inani eliphakeme kakhulu lepharamitha yobulukhuni bendawo: Isampula yobulukhuni be-Vickers 0.4 (Ra)/μm; umthwalo omncane wesampula yobulukhuni be-Vickers 0.2 (Ra)/μm; isampula yobulukhuni be-Vickers engu-0.1 (Ra)/μm
2) Ngomthwalo omncane we-Vickers kanye namasampula e-Vickers amancane, kunconywa ukuthi ukhethe ukupholisha okufanelekile nokupholishwa nge-electrolytic ukuze kuphathwe indawo engaphezulu ngokuya ngohlobo lwezinto ezibonakalayo.
3) Ugqinsi lwesampula noma isendlalelo sokuhlola kufanele okungenani sibe izikhathi ezingu-1.5 ubude be-diagonal bokuhlehlisa
I-4) Uma usebenzisa umthwalo omncane kanye nama-Vickers amancane ukuhlola, uma isampula lincane kakhulu noma lingajwayelekile, isampula kufanele ifakwe noma iboshwe ngento ekhethekile ngaphambi kokuhlolwa.
3Indlela yokuhlola
1) Ukukhethwa kwamandla okuhlola: Ngokusho kokuqina, ukujiya, usayizi, njll. wesampula, amandla okuhlola aboniswe kuThebula 4-10 kufanele akhethelwe ukuhlolwa. .
2) Isikhathi sokufaka isicelo se-test force: Isikhathi kusukela ekuqaleni kokufakwa kwamandla kuze kube sekuqedweni kokuhlolwa okuphelele kwesicelo kufanele sibe phakathi kwemizuzwana emi-2 ~ 10. Ngomthwalo omncane we-Vickers nokuhlolwa kokuqina kokuqina kwe-Vickers, isivinini sokwehla se-indenter akufanele sidlule u-0.2 mm/s. Isikhathi sokubamba amandla okuhlola yi-10~15 s. Okwezinto ezithambile ikakhulukazi, isikhathi sokubamba singanwetshwa, kodwa iphutha kufanele libe phakathi kuka-2.
3) Ibanga ukusuka enkabeni ye-indent kuya onqenqemeni lwesampula: Insimbi, ithusi ne-alloys yethusi kufanele ibe okungenani izikhathi ezingu-2.5 ubude be-diagonal be-indent; izinsimbi ezikhanyayo, umthofu, ithini kanye nama-alloys azo kufanele okungenani kube izikhathi ezi-3 ubude be-diagonal of the indentation. Ibanga phakathi kwezikhungo ze-indentations ezimbili eziseduze: ngensimbi, ithusi ne-alloys yethusi, kufanele kube okungenani izikhathi ezingu-3 ubude bomugqa we-diagonal we-stop mark; ngezinsimbi ezilula, umthofu, ithini nama-alloys azo, kufanele okungenani kube izikhathi eziyisi-6 ubude bomugqa we-diagonal we-indent.
4) Linganisa incazelo ye-arithmetic yobude bama-diagonal amabili e-indent, futhi uthole inani lokuqina kwe-Vickers ngokwethebula, noma ubale inani lokuqina ngokwefomula.
Umehluko kubude be-diagonal emibili ye-indent endizeni akufanele idlule i-5% yenani elijwayelekile lama-diagonals. Uma idlula, kufanele ibhalwe embikweni wokuhlola.
I-5) Uma uhlola isampula yendawo egobile, imiphumela kufanele ilungiswe ngokusho kwetafula.
6) Ngokuvamile, kunconywa ukubika amanani wokuhlola ubulukhuni amaphuzu amathathu kusampula ngayinye.
4 Ukuhlelwa komhloli wokuqina kwe-Vickers
Kunezinhlobo ezi-2 zokuhlola ubulukhuni be-Vickers ezivame ukusetshenziswa. Okulandelayo yisingeniso ekusetshenzisweni komhloli wokuqina wokuqina kwe-Vickers:
1. Uhlobo lwesilinganiso samehlo;
2. Uhlobo lokulinganisa lwesofthiwe
Isigaba 1: Uhlobo lwesilinganiso se-eyepiece Izici: Sebenzisa i-eyepiece ukuze ulinganise. Ukusetshenziswa: Umshini wenza (idayimane ◆) ukuhlehlisa, futhi ubude bedayimane bedayimane bulinganiswa nge-eyepiece ukuze kutholwe inani lokuqina.
Isigaba 2: Uhlobo lokulinganisa isofthiwe:Izici: Sebenzisa isofthiwe yokuqina ukuze ulinganise; elula futhi kulula emehlweni; ingakala ubulukhuni, ubude, igcine izithombe zokuhlehla, imibiko yokukhishwa, njll. Ukusetshenziswa: Umshini wenza (idayimane ◆) indentation, bese ikhamera yedijithali iqoqa ukuhlehlisa kukhompyutha, futhi inani lokuqina likalwa kukhompyutha.
5Ukuhlukaniswa kwesoftware: 4 izinguqulo eziyisisekelo, inguqulo yokulawula i-turret ezenzakalelayo, inguqulo ye-semi-automatic, nenguqulo ezenzakalelayo ngokugcwele.
1. Inguqulo eyisisekelo
Ingakwazi ukukala ubulukhuni, ubude, igcine izithombe zokuhlehlisa, imibiko yokukhipha, njll.;
2.Lawula isofthiwe yenguqulo ye-turret ezenzakalelayo ingalawula i-turret tester hardness, njenge-lens yenhloso, i-indenter, ukulayisha, njll.;
I-3.Inguqulo ye-Semi-automatic enetafula lokuhlola le-XY kagesi, ibhokisi lokulawula yesikhulumi se-2D; Ngokungeziwe kumsebenzi wenguqulo ye-turret ezenzakalelayo, isofthiwe ingasetha futhi izikhala namaphoyinti, amachashazi azenzakalelayo, ukulinganisa okuzenzakalelayo, njll.;
I-4.Inguqulo ezenzakalelayo egcwele enetafula lokuhlola le-XY kagesi, ibhokisi lokulawula yesikhulumi se-3D, ukugxila kwe-Z-axis; Ngokungeziwe kumsebenzi wenguqulo ye-semi-automatic, isofthiwe futhi inomsebenzi wokugxila we-Z-axis;
6Ungayikhetha kanjani i-Vickers hardness tester efanelekile
Intengo ye-Vickers tester hardness izohluka kuye ngokucushwa kanye nomsebenzi.
1. Uma ufuna ukukhetha eshibhe kakhulu, ungakhetha:
Imishini enesikrini esincane se-LCD kanye nokufaka kwe-diagonal manual ngokusebenzisa i-eyepiece;
2. Uma ufuna ukukhetha idivayisi engabizi, ungakhetha:
Izisetshenziswa ezinesikrini esikhulu se-LCD, i-eyepiece ene-encoder yedijithali, nephrinta eyakhelwe ngaphakathi;
3. Uma ufuna idivayisi esezingeni eliphezulu, ungakhetha:
Izisetshenziswa ezinesikrini sokuthinta, inzwa evaliwe, i-eyepiece enephrinta (noma i-USB flash drive), isikulufu sokuphakamisa igiya lezikelemu, kanye nesishumeki sedijithali;
4. Uma ucabanga ukuthi kuyakhathaza ukulinganisa ngeso, ungakhetha:
Ifakwe isistimu yokucubungula isithombe sokuqina kwe-CCD, ikala kukhompuyutha ngaphandle kokubheka i-eyepiece, elula, enembile, futhi esheshayo. Ungakwazi futhi ukukhiqiza imibiko futhi ugcine izithombe zokuhlehlisa, njll.
5. Uma ufuna ukusebenza okulula kanye ne-automation ephezulu, ungakhetha:
Isihloli sokuqina sokuqina kwe-Vickers esizenzakalelayo nesihloli sokuqina sokuqina kwe-Vickers esizenzakalelayo
Izici: setha isikhala nenani lamaphoyinti, ichashazi ngokuzenzakalelayo nangokuqhubekayo, futhi ulinganise ngokuzenzakalelayo.
