Lub tshuab ntsuas qhov nyuaj Universal yog qhov tseeb yog cov cuab yeej ntsuas kev ua tiav raws li ISO thiab ASTM cov qauv, tso cai rau cov neeg siv ua qhov kev ntsuas Rockwell, Vickers thiab Brinell hardness ntawm tib cov cuab yeej. Lub tshuab ntsuas qhov nyuaj universal yog kuaj raws li Rockwell, Brinell, thiab Vickers cov ntsiab cai es tsis txhob siv kev hloov pauv ntawm qhov system hardness los txiav txim siab ntau yam nqi hardness.
Peb qhov ntsuas qhov nyuaj uas tsim nyog rau kev ntsuas cov khoom ua haujlwm
Lub HB Brinell hardness scale yog tsim rau kev ntsuas qhov nyuaj ntawm cov hlau cam khwb cia, cov hlau tsis yog ferrous, thiab ntau yam hlau annealed thiab tempered. Nws tsis haum rau kev ntsuas cov qauv lossis cov khoom ua haujlwm uas nyuaj dhau, me dhau, nyias dhau, thiab tsis pub muaj qhov loj ntawm qhov chaw.
HR Rockwell hardness scale yog tsim rau: kev ntsuas qhov nyuaj ntawm kev sim pwm, quenching, quenching thiab tempering cua sov kho qhov chaw.
Lub HV Vickers hardness scale yog tsim rau kev ntsuas qhov nyuaj ntawm cov qauv thiab cov khoom nrog thaj chaw me me thiab cov nqi hardness siab, qhov nyuaj ntawm cov txheej infiltrated lossis coatings tom qab ntau yam kev kho deg, thiab qhov nyuaj ntawm cov ntaub ntawv nyias.
Cov khoom siv tshiab ntawm cov cuab yeej ntsuas qhov nyuaj thoob ntiaj teb
Txawv ntawm cov cuab yeej ntsuas qhov nyuaj thoob ntiaj teb ib txwm muaj: lub cuab yeej ntsuas qhov nyuaj thoob ntiaj teb tiam tshiab siv cov thev naus laus zis sensor thiab lub kaw lus teb rov qab los hloov cov qauv tswj hwm qhov hnyav, ua rau kev ntsuas yooj yim dua thiab tus nqi ntsuas ruaj khov dua.
Xaiv tau qib ntawm automation: tshuab taub hau tsis siv neeg nqa hom, kov npo digital zaub hom, computer ntsuas hom
Kev xaiv ntawm lub zog sim, hom zaub hardness thiab kev daws teeb meem hardness
