Hanyar gwajin taurin Rockwell 40Cr, 40 chromium

Bayan an kashe shi da kuma an rage zafi, chromium yana da kyawawan halaye na injiniya da kuma kyakkyawan taurarewa, wanda hakan ke sa a yi amfani da shi sau da yawa wajen ƙera maƙallan ƙarfi, bearings, gears, da camshafts. Halayen injiniya da gwajin tauri suna da matuƙar muhimmanci ga 40Cr da aka kashe da aka rage zafi.

Gwajin taurin 40Cr yawanci yana amfani da hanyar gwajin taurin Rockwell da hanyar gwajin taurin Brinell don gwaji. Saboda na'urar gwajin taurin Rockwell tana da sauri kuma mai sauƙin amfani, yawanci abokan ciniki ne suka fi son ta. Ga ƙananan sassa ko sassan da ke buƙatar daidaito mafi girma, ana iya amfani da na'urar gwajin taurin Vickers.

Yawanci, taurin Rockwell na 40Cr bayan an kashe shi da kuma an rage shi yawanci ana buƙatar ya kasance tsakanin HRC32-36, don haka yana da ƙarfi da juriya ga gajiya.

Ga wasu daga cikin na'urorin gwajin taurin Rockwell da ake amfani da su a yanzu:

1. Allon dijital na lantarki mai ƙara nauyi, na'urar gwajin taurin Rockwell: daidai, abin dogaro, mai ɗorewa, kuma ingantaccen gwaji; allon dijital zai iya karanta ƙimar taurin Rockwell kai tsaye, an inganta tsarin injin, kuma ana iya daidaita sauran ma'aunin Rockwell ta hanyar zaɓi. Yana amfani da fasahar ɗorawa da sauke kaya ta atomatik ta lantarki don kawar da kurakuran ɗan adam. Tsarin spindle yana amfani da tsarin spindle mara gogayya don inganta daidaiton ƙarfin gwajin farko.

2. Allon taɓawa na dijital na gwajin taurin Rockwell: Aikin allon taɓawa mai inci takwas, mai sauƙi kuma mai sauƙin aiki; ƙarfin gwajin lodin lantarki, ƙarancin gazawar, gwaji mafi daidaito, zai iya adana saitin bayanai 500 da kansa, kashe wuta ba tare da asarar bayanai ba, daidai da ISO, ASTM E18 da sauran ƙa'idodi.

3. Gwajin taurin Rockwell mai cikakken atomatik: Ana amfani da ƙarfin gwajin lodin lantarki don inganta daidaiton ƙimar ƙarfi, dannawa ɗaya don kammala dukkan tsarin gwajin taurin, mai sauƙi da inganci; babban dandamalin gwaji, mafi dacewa don gano taurin aiki na manyan ayyuka; sanye take da joystick don tuƙi motar servo cikin sauri don daidaita sararin gwajin; ana iya aika bayanai zuwa kwamfuta ta hanyar RS232, Bluetooth ko USB.
