Hanyoyin gwajin taurin Rockwell Knoop da Vickers don yumbu na aluminum nitride da hanyoyin gwaji don bearings na birgima na ƙarfe

1. Hanyar gwajin taurin Rockwell Knoop Vickers don yumbu na aluminum nitride
Tunda kayan yumbu suna da tsari mai rikitarwa, suna da tauri da rauni a yanayi, kuma suna da ƙananan nakasu a cikin filastik, hanyoyin bayyana tauri da aka saba amfani da su sun haɗa da tauri na Vickers, tauri na Knoop da tauri na Rockwell. Kamfanin Shancai yana da nau'ikan na'urorin gwada tauri iri-iri, tare da gwaje-gwajen tauri daban-daban da na'urorin gwada tauri daban-daban.
Ana iya amfani da waɗannan ƙa'idodi a matsayin nuni:
Gwajin Taurin Rockwell na GB/T 230.2:
Akwai ma'aunin taurin Rockwell da yawa, kuma kayan yumbu gabaɗaya suna amfani da ma'aunin HRA ko HRC.
GB/T 4340.1-1999 Gwajin taurin ƙarfe Vickers da GB/T 18449.1-2001 Gwajin taurin ƙarfe.
Hanyoyin auna Knoop da Micro-Vickers iri ɗaya ne, bambancin shine nau'ikan indexers daban-daban da ake amfani da su.
Ya kamata a lura cewa saboda yanayin musamman na samfurin, za mu iya cire ƙofofin Vickers marasa inganci bisa ga yanayin ƙofofin yayin aunawa don samun ƙarin bayanai masu inganci.
2. Hanyoyin gwaji don bearings na birgima na ƙarfe
Dangane da hanyoyin gwajin tauri don sassan ƙarfe da ƙarfe marasa ƙarfe da aka ƙayyade a cikin JB/T7361-2007, akwai hanyoyi da yawa na gwaji bisa ga tsarin aikin, duk waɗanda za a iya gwada su da na'urar gwajin tauri ta Shancai:
1) Hanyar gwajin taurin Vickers
Gabaɗaya, ana gwada sassan bearings masu tauri a saman ta hanyar amfani da hanyar gwajin tauri ta Vickers. Ya kamata a mai da hankali kan ƙarshen saman kayan aikin da kuma zaɓin ƙarfin gwajin.
2) Hanyar gwajin taurin Rockwell
Ana gudanar da yawancin gwaje-gwajen taurin Rockwell ta amfani da ma'aunin HRC. Shancai Rockwell mai gwajin taurin kai ya tara shekaru 15 na gwaninta kuma yana iya biyan duk buƙatu.
3) Hanyar gwajin taurin Leeb
Ana iya amfani da gwajin taurin Leeb don bearings da aka sanya ko kuma waɗanda ke da wahalar wargazawa. Daidaiton ma'auninsa bai yi kyau kamar na na'urar gwajin taurin benchtop ba.
Wannan ma'auni ya fi dacewa da gwajin tauri na sassan ɗaukar ƙarfe, sassan ɗaukar ƙarfe masu annealed da tempered da sassan ɗaukar ƙarfe da aka gama da kuma sassan ɗaukar ƙarfe marasa ƙarfe.
