Txhua qhov chaw kho cua sov yuav tsum dhau qhov kev sim qhov nyuaj raws li cov lus qhia tshwj xeeb ntawm cov duab kos thiab cov kev cai ntawm cov ntaub ntawv txheej txheem. Lub tshuab ntsuas qhov nyuaj yuav tsum tau calibrated nrog cov qauv ntsuas qhov nyuaj ua ntej kuaj, thiab kev sim qhov nyuaj tsuas yog tuaj yeem ua tiav tom qab dhau qhov calibration.
Ua ntej yuav kuaj xyuas qhov nyuaj, qhov chaw sim ntawm cov khoom yuav tsum tau ntxuav kom huv si kom tshem tawm cov nplai, cov txheej decarburized, burrs thiab lwm yam kab mob. Yuav tsum tsis txhob muaj cov cim qhia meej ntawm cov cuab yeej ua haujlwm nyob rau ntawm qhov chaw sim. Cov khoom yuav tsum tau kuaj ntawm qhov kub hauv chav tsev raws li tus qauv. Yog tias qhov kub ntawm qhov workpiece siab dua qhov kub ib puag ncig me ntsis, kev kuaj yuav tsum tsis txhob ua mus txog thaum qhov workpiece tuav tau ruaj khov nrog tes.
Cov ntsiab lus sim qhov nyuaj yuav tsum tau teeb tsa raws li tau teev tseg hauv cov ntaub ntawv txheej txheem. Yog tias tsis muaj cov kev cai meej, cov ntsiab lus sim yuav tsum tau txiav txim siab ua ke los ntawm cov kws ua haujlwm txheej txheem thiab cov neeg soj ntsuam.
Yuav Ua Li Cas Xaiv Ib Lub Tester Hardness Uas Haum Rau Cov Khoom Siv Kho Kub
1. Cov cuab yeej ntsuas qhov nyuaj Brinell siv rau cov khoom siv ib txwm muaj, annealed thiab quenched & tempered. Cov khoom ua haujlwm ntawm hom no muaj qhov nyuaj tag nrho qis, ductility zoo thiab cov qauv sab hauv sib xws. Lub tshuab cemented carbide loj-txoj kab uas hla ntawm Brinell testers tsim thaj chaw dav dav uas npog ntau cov qauv metallographic. Qhov nruab nrab ntawm kev nyeem ntawv qhov nyuaj tau txais yog ruaj khov dua thiab tuaj yeem cuam tshuam tag nrho cov khoom siv kho tshuab ntawm cov khoom siv.
2. Cov cuab yeej ntsuas qhov nyuaj Brinell hom rauj siv tau rau cov khoom ua haujlwm loj uas tsis tuaj yeem ntsia tau rau ntawm cov cuab yeej ntsuas lub rooj ntev zaum, ua rau muaj kev tshuaj xyuas sai sai ntawm qhov chaw yam tsis tau txiav cov qauv.
3.Cov cuab yeej ntsuas Rockwell hardness siv rau cov khoom uas tau quenched. Cov workpieces uas tau quenched no muaj qhov nyuaj siab thiab qhov brittleness siab. Lub Rockwell diamond cone indenter tuaj yeem tiv taus lub zog xeem siab thiab yooj yim ntsuas qhov nyuaj siab. Nws qhov me me indentation yuav tsis ua rau puas tsuaj rau cov nto tiav. Nrog rau kev sim sai thiab kev nyeem ncaj qha, nws tsim nyog rau kev tshuaj xyuas ntau ntawm cov khoom tiav suav nrog cov shafts, pwm thiab iav. Nruab nrog lub rooj ua haujlwm V-hom, nws tuaj yeem clamp cov workpieces puag ncig.
4.Cov Vickers hardness testers yuav tsum tau siv rau cov khoom carburized thiab cov workpieces nrog cov txheej nyias nyias hardened. Cov workpieces carburized thiab nitrided tsuas muaj ib txheej nyias nyias hardened nrog ib lub substrate mos mos hauv qab. Vickers testers txhawb nqa cov kev sim me me thiab tsim cov indentations ntiav heev uas ua haujlwm tsuas yog rau ntawm qhov chaw hardened yam tsis tau nkag mus rau hauv lub substrate. Qhov no tso cai rau kev ntsuas qhov tseeb ntawm qhov tseeb ntawm qhov nyuaj ntawm qhov chaw.
Cov saum toj no tsuas yog cov lus qhia dav dav rau kev xaiv cov khoom siv ntsuas qhov nyuaj. Cov xwm txheej xeem tiag tiag yog qhov nyuaj, thiab kev xaiv cov khoom siv cuam tshuam los ntawm qhov loj ntawm cov khoom siv, qhov tuab ntawm cov txheej tawv, thiab qhov xwm txheej machining. Qhov kev xaiv kawg yuav tsum txiav txim siab raws li qhov xwm txheej tiag tiag ntawm cov khoom siv. Yog tias koj ntsib teeb meem hauv kev xaiv qauv, thov hu rau peb.Laizhou LaihuaPeb muab cov kev daws teeb meem kev sim khoom siv rau kev sim khoom siv ib leeg rau ib leeg.
