1 Shiri kafin gwaji
1) Mai gwajin tauri da kuma indent da ake amfani da shi don gwajin tauri na Vickers ya kamata su bi tanadin GB/T4340.2;
2) Ya kamata a sarrafa zafin ɗakin a cikin kewayon 10 ~ 35℃. Ga gwaje-gwajen da ke da buƙatu mafi girma, ya kamata a sarrafa shi a (23±5)℃.
Samfura 2
1) Ya kamata saman samfurin ya kasance mai faɗi kuma santsi. Ana ba da shawarar cewa ƙaiƙayin saman samfurin ya cika buƙatun: Matsakaicin ƙimar sigar ƙaiƙayin saman: Samfurin tauri na Vickers 0.4 (Ra)/μm; ƙaramin kaya Samfurin tauri na Vickers 0.2 (Ra)/μm; samfurin tauri na Vickers 0.1 (Ra)/μm
2) Ga samfuran Vickers da micro Vickers masu ƙananan kaya, ana ba da shawarar zaɓar gogewa da gogewar electrolytic da ta dace don maganin saman ruwa bisa ga nau'in kayan.
3) Kauri na samfurin ko layin gwaji ya kamata ya zama aƙalla sau 1.5 na tsawon diagonal na indent ɗin
4) Lokacin amfani da ƙananan kaya da ƙananan Vickers don gwaji, idan samfurin ƙarami ne ko kuma ba daidai ba ne, ya kamata a saka samfurin a ciki ko a manne shi da wani kayan aiki na musamman kafin a gwada.
3Hanyar gwaji
1) Zaɓin ƙarfin gwaji: Dangane da tauri, kauri, girma, da sauransu na samfurin, ƙarfin gwajin da aka nuna a Tebur 4-10 ya kamata a zaɓa don gwajin.
2) Lokacin amfani da ƙarfin gwaji: Lokacin daga farkon amfani da ƙarfi zuwa kammala cikakken amfani da ƙarfin gwaji ya kamata ya kasance cikin daƙiƙa 2 ~ 10. Ga ƙananan gwaje-gwajen taurin Vickers da micro Vickers, saurin saukowa na indent bai kamata ya wuce 0.2 mm/s ba. Lokacin riƙe ƙarfin gwaji shine daƙiƙa 10 ~ 15. Ga kayan da suka yi laushi, ana iya tsawaita lokacin riƙewa, amma kuskuren ya kamata ya kasance cikin daƙiƙa 2.
3) Nisa daga tsakiyar maɓalli zuwa gefen samfurin: Ya kamata ƙarfe, jan ƙarfe da ƙarfe su kasance aƙalla sau 2.5 tsawon maɓalli; ƙarfe masu sauƙi, gubar, tin da ƙarfen su ya kamata su kasance aƙalla sau 3 tsawon maɓalli. Nisa tsakanin cibiyoyin maɓalli guda biyu masu maƙwabtaka: ga ƙarfe, jan ƙarfe da ƙarfen tagulla, ya kamata ya zama aƙalla sau 3 tsawon layin maɓalli na alamar tsayawa; ga ƙarfe masu sauƙi, gubar, tin da ƙarfen su, ya kamata ya zama aƙalla sau 6 tsawon layin maɓalli na maɓalli
4) A auna matsakaicin lissafi na tsawon diagonal guda biyu na indentation, sannan a nemo ƙimar taurin Vickers bisa ga tebur, ko a ƙididdige ƙimar taurin bisa ga dabarar.
Bambancin tsawon diagonal biyu na indentation a kan jirgin bai kamata ya wuce kashi 5% na matsakaicin ƙimar diagonal ba. Idan ya wuce, ya kamata a lura da shi a cikin rahoton gwaji.
5) Lokacin gwaji akan samfurin saman da aka lanƙwasa, ya kamata a gyara sakamakon bisa ga teburin.
6) Gabaɗaya, ana ba da shawarar a bayar da rahoton ƙimar gwajin tauri na maki uku ga kowane samfurin.
Rarraba masu gwajin taurin Vickers guda 4
Akwai nau'ikan gwajin taurin Vickers guda biyu da aka fi amfani da su. Ga yadda ake amfani da gwajin taurin Vickers:
1. Nau'in aunawa na ido;
2. Nau'in ma'aunin software
Rarraba 1: Nau'in aunawa na ido Siffofi: Yi amfani da na'urar ido don aunawa. Amfani: Injin yana yin lanƙwasa (lu'u-lu'u ◆), kuma ana auna tsawon diagonal na lu'u-lu'u da na'urar ido don samun ƙimar tauri.
Rarraba 2: Nau'in auna software: Siffofi: Yi amfani da software mai tauri don aunawa; mai dacewa kuma mai sauƙin gani; yana iya auna tauri, tsayi, adana hotunan shiga, rahotannin fitarwa, da sauransu. Amfani: Injin yana yin ƙoƙon (lu'u-lu'u ◆), kuma kyamarar dijital tana tattara ƙoƙon da ke kan kwamfutar, kuma ana auna ƙimar tauri akan kwamfutar.
5Rarraba Software: Sigogi 4 na asali, sigar sarrafa turret ta atomatik, sigar rabin-atomatik, da sigar cikakken atomatik.
1. Sigar asali
Zai iya auna tauri, tsayi, adana hotunan shiga, rahotannin fitarwa, da sauransu.
2. Manhajar sarrafa sigar turret ta atomatik na iya sarrafa turret ɗin gwajin tauri, kamar, ruwan tabarau na zahiri, indenter, lodawa, da sauransu.
3. Sigar Semi-atomatik tare da teburin gwaji na XY na lantarki, akwatin sarrafa dandamali na 2D; Baya ga aikin sigar turret ta atomatik, software ɗin kuma zai iya saita tazara da maki, digging ta atomatik, auna atomatik, da sauransu.
4. Sigar atomatik cikakke tare da teburin gwaji na XY na lantarki, akwatin sarrafa dandamali na 3D, mayar da hankali kan axis na Z; Baya ga aikin sigar rabin-atomatik, software ɗin yana da aikin mayar da hankali kan axis na Z;
6Yadda ake zaɓar mai gwajin taurin Vickers mai dacewa
Farashin mai gwajin taurin Vickers zai bambanta dangane da tsari da aikin.
1. Idan kana son zaɓar mafi arha, to za ka iya zaɓar:
Kayan aiki tare da ƙaramin allon LCD da shigarwar diagonal ta hannu ta cikin akwatin ido;
2. Idan kana son zaɓar na'ura mai rahusa, to za ka iya zaɓar:
Kayan aiki masu babban allon LCD, kayan gani mai lambar dijital, da firintar da aka gina a ciki;
3. Idan kana son na'ura mai inganci, to zaka iya zaɓar:
Kayan aiki masu allon taɓawa, na'urar firikwensin rufewa, na'urar ido mai firinta (ko kebul na flash drive), sukurin ɗaga kaya na tsutsa, da kuma na'urar ɓoye bayanai ta dijital;
4. Idan kana ganin yana da gajiya a auna da ido, to za ka iya zaɓar:
An sanye shi da tsarin sarrafa hotunan CCD mai tauri, ana auna su akan kwamfuta ba tare da duba abin da ke cikin ido ba, wanda yake da sauƙi, mai sauƙin fahimta, kuma mai sauri. Hakanan zaka iya samar da rahotanni da adana hotunan da aka saka a ciki, da sauransu.
5. Idan kana son aiki mai sauƙi da kuma aiki da kai mai inganci, to za ka iya zaɓar:
Mai gwajin taurin Vickers ta atomatik da mai gwajin taurin Vickers ta atomatik
Siffofi: saita tazara da adadin maki, ta atomatik da ci gaba da nuna maki, kuma auna ta atomatik.
