Kev ntsuam xyuas qhov nyuaj ntawm cov khoom siv thauj khoom thiab qhov tawg ntawm qhov tawv nqaij Vickers kev ntsuam xyuas qhov nyuaj ntawm cov cuab yeej cemented carbide

Nws yog ib qho tseem ceeb heev uas yuav tsum kuaj qhov nyuaj ntawm lub anchor ua haujlwm clip. Lub clip yuav tsum muaj qee qhov nyuaj thaum siv kom ntseeg tau tias nws txoj haujlwm ntseeg tau thiab ruaj khov. Laihua Company tuaj yeem kho ntau yam clamps tshwj xeeb raws li qhov xav tau, thiab tuaj yeem siv Laihua lub hardness tester rau kev kuaj qhov nyuaj.
Tus qauv xeem hardness ntawm lub anchor clip feem ntau yog hais txog:
1. Rockwell hardness GB / T 230.1-2018
Tus qauv no siv txoj kev kuaj Rockwell hardness thiab HRC Rockwell hardness scale rau kev kuaj, Txoj kev kuaj no yooj yim rau kev khiav lag luam thiab yog qhov kev xaiv zoo tshaj plaws rau cov neeg siv khoom.
2. Brinell hardness GB/T231.1-2018.
Tus qauv no siv Brinell hardness HB scale rau kev sim.
Tus qauv ntsuam xyuas hais txog:
GB/T 14370-2015 los yog JT/T 329-2010.
Vim yog qhov tshwj xeeb ntawm cov duab ntawm lub anchor clip, raws li tus neeg siv khoom lub clip taper loj thiab lub clip sab hauv txoj kab uas hla, thaum yuav lub hardness tester, nws yog qhov tsim nyog los kho cov cuab yeej tshaj lij raws li qhov xav tau kom ntseeg tau qhov tseeb ntawm tus nqi ntsuas thiab txuas ntxiv lub neej ua haujlwm ntawm lub hardness tester. Yog tias tsim nyog, thov koj xa cov qauv xa tuaj rau kev sim.
Txoj kev sim rau qhov tawg ntawm cov cuab yeej cemented carbide los ntawm Vickers hardness (siv Vickers hardness tester):
Feem ntau, qhov nyuaj ntawm cemented carbide yuav tsum tau sim siv Rockwell hardness A scale. Thaum lub thickness ntawm workpiece lossis qauv tsawg dua 1.6 hli, Vickers hardness method siv tau rau kev sim. Yog li ntawd, txoj kev sim qhov tawg ntawm cov cuab yeej cemented carbide yog dab tsi?
Tus qauv ntsuas kev tawv ntawm pob txha tawg thiab tus qauv siv txoj kev ntsuas kev tawv ntawm pob txha tawg rau cov ntaub ntawv cemented carbide: JB/T 12616—2016;
Txoj kev sim yog raws li nram no:
Ua ntej, ua cov khoom ua haujlwm kom raug kuaj rau hauv cov qauv, tom qab ntawd txhuam qhov chaw ntawm cov qauv mus rau hauv qhov chaw iav, thiab muab tso rau hauv qab lub tshuab ntsuas microhardness kom tsim tau qhov indentation ntawm qhov chaw polished nrog lub pob zeb diamond conical indenter ntawm lub tshuab ntsuas qhov nyuaj, yog li cov kab nrib pleb prefabricated tau tsim ntawm plaub qhov chaw ntawm qhov indentation.
Tus nqi ntawm qhov tawg uas tawv (KIC) yog xam raws li qhov hnyav ntawm qhov indentation P thiab qhov ntev ntawm qhov tawg indentation C.
Laizhou Laihua Testing Instrument Factory yeej ib txwm muaj los teb cov lus nug uas koj muaj.
