40Cr, Hanyar gwajin taurin chromium Rockwell 40

Bayan quenching da tempering, chromium yana da kyawawan kaddarorin inji da kuma tauri mai kyau, wanda ke sa shi sau da yawa ana amfani da shi wajen kera na'urori masu ƙarfi, bearings, gears, da camshafts. Kaddarorin injina da gwajin taurin suna da matukar mahimmanci don kashewa da zafin jiki 40Cr.

Gwajin taurin 40Cr yawanci yana amfani da hanyar gwajin taurin Rockwell da hanyar gwajin taurin Brinell don gwaji. Saboda gwajin taurin Rockwell yana da sauri da dacewa don amfani, yawanci abokan ciniki sun fi son shi. Don ƙananan sassa ko ɓangarorin da ke buƙatar daidaito mafi girma, ana iya amfani da ma'aunin taurin Vickers.

Yawancin lokaci, taurin Rockwell na 40Cr bayan quenching da tempering yawanci ana buƙata ya kasance tsakanin HRC32-36, don ya sami ƙarfin ƙarfi da juriya ga gajiya.

Wadannan sune masu gwajin taurin Rockwell da yawa da ake amfani dasu don tunani:

1. Nunin dijital na dijital mai nauyi mai nauyi na Rockwell hardness tester: daidai, abin dogaro, dorewa, da ingantaccen gwajin gwaji; nunin dijital na iya karanta ƙimar taurin Rockwell kai tsaye, an inganta tsarin injina, kuma sauran ma'aunin Rockwell ana iya daidaita su ta zaɓin zaɓi. Yana ɗaukar fasahar lodi ta atomatik da kuma sauke kayan aiki don kawar da kurakuran ɗan adam. Tsarin spindle yana ɗaukar tsarin dunƙule mara ƙarfi don inganta daidaiton ƙarfin gwajin farko

2. Nunin allo na dijital na Rockwell mai gwada taurin ƙarfi: aikin allon taɓawa na inch takwas, mai sauƙi da sauƙin aiki; Ƙarfin gwajin lodin lantarki, ƙarancin gazawa, ingantaccen gwaji, na iya adana saitin bayanai da kansa 500, kashe wuta ba tare da asarar bayanai ba, daidai da ISO, ASTM E18 da sauran ka'idoji.

3. Cikakken atomatik mai gwada ƙarfi na Rockwell: Ana amfani da ƙarfin gwajin gwaji na lantarki don inganta ƙimar ƙimar ƙarfin ƙarfi, danna sau ɗaya don kammala duk tsarin gwajin ƙarfi, mai sauƙi da inganci; babban dandali na gwaji, mafi dacewa don gano taurin babban aiki; sanye take da joystick don fitar da motar servo da sauri don daidaita wurin gwaji; Ana iya watsa bayanai zuwa kwamfuta ta hanyar RS232, Bluetooth ko USB.
