Ib Kauj Ruam Qhia Txog Kev Xaiv Hom Zoo
Xaiv raws li tsib qhov ntev: qhov loj ntawm qhov workpiece, cov khoom siv, qhov nyuaj, qhov yuav tsum tau ua kom raug, thiab cov xwm txheej ntawm kev siv. Tsis tas yuav txhawj, tsuas yog ua raws li phau ntawv qhia thiab koj tuaj yeem txiav txim siab.
I. Ua ntej, faib ua peb hom loj ntawm cov neeg ntsuas qhov nyuaj
1. Rockwell Hardness Tester (HRC/HRB/HRA)
Haum rau: hlau quenched, hlau tuag, bearings, cov cuab yeej, cov khoom kho cua sov
Qhov zoo: kev ua haujlwm siab, siv dav hauv cov qauv hauv tebchaws, cov khoom siv txheem rau kev tshuaj xyuas zoo hauv Hoobkas
Qhov tsis zoo: yuav tsum coj cov qauv / hom desktop, cov khoom loj tsis tuaj yeem txav mus los yog sim ntawm qhov chaw
Yuav ntsuas li cas:
HRC: cov hlau uas tau quenched high-hardness (dies, cutter, gears)
HRB: tooj dag, txhuas, cov hlau uas tsis muaj carbon, cov hlau mos
2. Brinell Hardness Tester (HB)
Haum rau: hlau cam khwb cia, hlau cam khwb cia, txhuas alloy, tooj liab alloy, ntxhib forged qhov chaw
Cov Zoo: qhov loj indentation, qhov tseeb tshaj plaws rau cov ntaub ntawv ntxhib thiab tsis sib xws
Qhov tsis zoo: qhov loj me, ua puas tsuaj, ua haujlwm tsis zoo, tsim nyog rau kev kuaj xyuas qhov chaw hauv chaw kuaj mob
3. Leeb Hardness Tester (portable HL rau HRC / HB / HV) —YY251D Leeb Hardness Tester
Haum rau: cov khoom loj, kev sim ntawm qhov chaw, cov khoom uas tsis tuaj yeem rhuav tshem tau, pwm hnyav, yob, shafts
Qhov Zoo: tuav tes thiab nqa tau yooj yim, tsis ua puas tsuaj, tsis tas yuav coj cov qauv, siv tau rau hauv txoj haujlwm ntsug, kab rov tav, lossis saum taub hau
Qhov tsis zoo: qhov tseeb qis dua me ntsis dua li desktop Rockwell, qhov yuam kev loj rau cov khoom nyias nyias thiab cov khoom me me
II. Xaiv raws li cov xwm txheej ntawm kev siv (qhov ua tau zoo tshaj plaws)
Xwm txheej 1: chav kuaj ua haujlwm, kev tshuaj xyuas zoo ntawm cov khoom siv / kev kho cua sov, xav tau qhov tseeb siab Xaiv lub desktop Rockwell hardness tester
Nyiam siv rau cov khoom siv dav dav, cov chaw tsim pwm, thiab cov chaw kho cua sov.
Xwm txheej 2: hlau cam khwb cia, castings, txhuas alloy, cov khoom forged ntxhib
Xaiv lub Brinell hardness tester
Xwm txheej 3: cov khoom loj uas tsis tuaj yeem txav mus los, kev sim ntawm qhov chaw, pwm / yob / cov ncej loj Yuav tsum xaiv lub tshuab ntsuas Leeb hardness uas nqa tau
Xwm txheej 4: cov khoom me me, cov ntawv nyias nyias, qhov nyuaj ntawm cov txheej carburized thiab nitrided Xaiv lub Vickers hardness tester (HV)
Haum rau: cov ntawv nyias nyias, cov npoo cuab yeej, cov txheej txheej, cov txheej tawv.
III. Xaiv raws li qhov tuab / qhov loj ntawm workpiece
Cov khoom loj, hnyav, thiab tsis txav tau → Leeb
Cov qauv txheem, cov khoom me me, tuaj yeem muab tso rau ntawm lub desktop → Rockwell
Cov khoom nyias nyias < 3 hli, cov txheej tawv tawv saum npoo → Vickers
Kev ua cov khoom seem, cov khoom tsis sib xws → Brinell
IV. Xaiv raws li qib hardness
Cov ntaub ntawv mos: txhuas, tooj liab, hlau carbon tsawg → HRB / HB
Nruab nrab hardness: quenched thiab tempered hlau, structural steel → HRC / HB
Kev nyuaj siab: cov tuag quenched, cov cuab yeej, cov bearings → HRC / HV
Cov txheej txheej nyias heev / cov txheej carburized → HV Vickers
