Hauv kev tsim khoom ntawm cov khoom siv kho vajtse, hardness yog qhov taw qhia tseem ceeb. Coj ib feem qhia hauv daim duab ua piv txwv. Peb tuaj yeem siv Rockwell hardness tester los kuaj qhov tawv.
Peb cov khoom siv hluav taws xob siv hluav taws xob siv cov duab Rockwell hardness tester yog cov cuab yeej siv tau zoo rau lub hom phiaj no. Cov txheej txheem kuaj ntawm no hardness tester yog heev yooj yim thiab intuitive.
Nws siv lub zog ntawm 150kgf thiab siv lub pob zeb diamond indenter rau kev xeem. Tom qab qhov kev xeem tiav lawm, qhov ntsuas hardness tus nqi yog raws li HRC Rockwell hardness scale. Txoj kev no ntawm kev siv Rockwell hardness tester tau dav lees paub thiab siv hauv kev lag luam rau nws qhov tseeb thiab yooj yim. Nws ua rau cov tuam txhab lag luam ntsuas qhov nyuaj ntawm cov khoom siv kho vajtse kom raug, kom ntseeg tau tias cov khoom ua tau raws li cov qauv tsim nyog. Txawm hais tias nws yog nyob rau hauv kev tsim khoom ntawm cov khoom siv tshuab, kev tsim kho kho vajtse, lossis lwm yam kev lag luam, kev tshawb pom tseeb ntawm hardness yog qhov tseem ceeb rau kev ua haujlwm thiab kev pabcuam lub neej ntawm cov khoom.
Peb lub hardness tester tsis tsuas yog muab cov txiaj ntsig kev soj ntsuam txhim khu kev qha, tab sis kuj ua kom yooj yim rau cov txheej txheem kev ua haujlwm, uas ua rau muaj txiaj ntsig zoo ntawm kev tswj hwm zoo hauv cov txheej txheem ntawm cov khoom siv kho vajtse.
Ntawm no yog cov ncauj lus kom ntxaws cov kauj ruam rau kev siv cov hluav taws xob quab yuam-tsim digital zaub Rockwell hardness tester ntawm Shandong Shancai Company los ntsuas qhov hardness ntawm hardware standard seem raws li Rockwell hardness test method rau cov khoom siv hlau:
- Npaj cov tester thiab cov qauv:
1.1Xyuas kom meej tias cov khoom siv hluav taws xob siv hluav taws xob siv cov khoom siv Rockwell hardness tester raug ntsuas kom raug thiab ua haujlwm zoo. Txheeb xyuas tag nrho cov kev sib txuas thiab kev ua haujlwm, xws li cov khoom siv hluav taws xob, cov khoom siv digital, thiab cov ntawv thov siv zog.
1.2Xaiv lub hardware standard part specimen mus kuaj. Xyuas kom tseeb tias qhov saum npoo ntawm cov qauv yog huv si, tsis muaj av, roj, lossis oxide txheej. Yog tias tsim nyog, txhuam qhov saum npoo kom tau qhov chaw kuaj du thiab tiaj tus.
2. Nruab lub indenter: Xaiv lub pob zeb diamond indenter uas tsim nyog raws li qhov yuav tsum tau ua. Rau kev ntsuas qhov hardness ntawm HRC Rockwell hardness scale, nruab lub pob zeb diamond indenter rau hauv tester lub indenter tuav. Xyuas kom meej tias lub indenter yog ruaj khov thiab ua kom zoo.
3. Teeb lub zog kuaj: Kho lub tester los teeb tsa lub zog rau 150kgf. Qhov no yog tus qauv xeem quab yuam rau HRC nplai. Paub meej tias qhov kev teeb tsa quab yuam yog qhov tseeb los ntawm tus neeg soj ntsuam cov tswj vaj huam sib luag lossis cov txheej txheem hloov kho cuam tshuam.
4. Tso tus qauv: Muab cov qauv tso rau ntawm tus ntsuas lub qhov quav. Siv cov khoom siv tsim nyog lossis cov cuab yeej tso tawm kom ntseeg tau tias cov qauv yog qhov ruaj khov thiab ruaj khov, thiab qhov ntsuas qhov chaw yog perpendicular mus rau lub indenter lub axis.
5.Hardness tester txiav loading, nyob, unloading
6.Nyeem tus nqi hardness: Thaum lub indenter raug tshem tawm tag nrho, tus tester lub digital zaub yuav qhia qhov ntsuas hardness nqi ntawm HRC Rockwell hardness scale. Sau tus nqi no kom raug.
7. Rov ua qhov kev xeem (yog tias tsim nyog): Txhawm rau kom tau txais txiaj ntsig zoo dua, nws raug nquahu kom rov ua cov kauj ruam saum toj no ntawm cov haujlwm sib txawv ntawm cov qauv ntawm qhov chaw thiab suav cov nqi nruab nrab ntawm ntau qhov kev ntsuas. Qhov no yuav pab txo qis qhov yuam kev los ntawm cov khoom tsis sib xws ntawm cov qauv ntawm qhov chaw.
Los ntawm ua raws li cov kauj ruam no ua tib zoo, koj tuaj yeem ntsuas qhov hardness ntawm hardware standard seem siv Rockwell hardness test method nrog hluav taws xob siv hluav taws xob siv cov duab Rockwell hardness tester.
