Nyob rau hauv kev tsim cov khoom siv kho vajtse, Hardness yog qhov taw qhia tseem ceeb. Ua qhov uas qhia hauv daim duab ua piv txwv. Peb tuaj yeem siv lub pob zeb ua pob zeb nyuaj rau kev ua haujlwm nyuaj.
Peb lub zog hluav taws xob-ua tiav cov zaub cov zaub rockwell hardness tester yog cov cuab yeej siv tau zoo rau lub hom phiaj no. Cov txheej txheem ntsuas ntawm lub testness no yog qhov yooj yim heev thiab intuitive.
Nws siv lub zog ntawm 150kgf thiab siv ib lub pob zeb diamond indenter rau kev sim. Tom qab qhov kev sim ua tiav, ntsuas tus nqi tawv tau raws li HRC rockead hardness nplai. Hom no ntawm kev siv Rockwell Hardness Tester tau pom dav thiab thov hauv kev lag luam rau nws qhov raug thiab yooj yim. Nws ua rau cov tuam ntxhab kom raug ntsuas qhov nyuaj ntawm cov khoom kho vajtse, kom cov khoom uas cov khoom lag luam uas yuav tsum tau ua. Txawm hais tias nws yog nyob rau hauv kev tsim kho tshuab cov tshuab, siv cov khoom siv cuam tshuam, lossis nrhiav tau tseeb yog qhov ua tau zoo thiab kev pabcuam lub neej ntawm cov khoom lag luam.
Peb cov tub ntaus ntawv tawv tsis tsuas muab cov txheej txheem ntsuas kev ua haujlwm tab sis tseem ua kom yooj yim txhim kho kev tswj hwm ua haujlwm hauv cov khoom siv ntau lawm.
Ntawm no yog cov ncauj lus ntsuas cov ncauj lus rau kev siv hluav taws xob-ua tiav cov khoom siv hluav taws xob ntawm cov qauv siv hluav taws xob raws li cov khoom siv Rockwell lub hardness
- Npaj cov tester thiab hnoos qeev:
1.1Xyuas kom meej tias lub zog hluav taws xob-thov cov zaub cov zaub pob zeb hluav taws xob lub zog ua haujlwm tau ntsuas kom zoo thiab ua haujlwm zoo. Txheeb xyuas txhua qhov sib txuas thiab cov haujlwm, xws li lub zog hluav taws xob, Digital zaub, thiab yuam kev thov cov txheej txheem.
1.2Xaiv cov qauv kho vajtse hom kev ua rau cov qauv coj los kuaj. Nco ntsoov tias cov hnoos qeev saum npoo av yog huv, dawb ntawm tej av, roj, lossis cov roj oxide. Yog tias tsim nyog, txhuam lub saum npoo kom tau txais qhov chaw du thiab tiaj tus.
2. Nruab ib qho indenter: Xaiv lub pob zeb diamond tsim nyog raws li kev xeem. Rau kev ntsuas lub hardness ntawm HRC Rockwell Hardness Nplai, Nruab Pob Zeb Diamond indenter rau hauv tester tus neeg ua haujlwm Indenter. Xyuas kom meej tias tus indenter yog ruaj khov thiab ua raws cai.
3. Teem lub zog xeem: Kho tus tester los teeb yuam kev rau 150kgf. Nov yog tus qauv ntsuas kev quab yuam rau HRC nplai. Paub meej tias lub zog quab yuam yog muaj tseeb los ntawm tester tus tswj vaj huam sib luag lossis kev hloov kho tshuab.
4. Txoj Haujlwm Ib Zauv: Muab cov zis rau ntawm tester's Thenvil. Siv cov khoom siv tsim nyog los yog muab cov khoom siv ua kom ntseeg tau tias qhov quav yog khov kho thiab ruaj khov, thiab cov npoo ntsuas yog qhov sib dhos rau cov neeg sab nrauv.
5.Huardness tester cia li thauj khoom, nyob, thauj khoom
6.Nyeem cov nqi hardness: Thaum tus neeg sab nrauv tau tshem tawm tag nrho, tus tester's Digital Display yuav qhia qhov kev ntsuas ntsuas ntawm HRC Rockwell Hardness Nplai. Sau cov nqi no kom raug.
7. Rov ua qhov kev xeem (yog tias tsim nyog): Rau cov txiaj ntsig tau ntau dua, nws raug nquahu kom rov ua cov theem saum toj no ntawm cov hnoos qeev saum toj no thiab xam cov nqi nruab nrab ntawm ntau qhov ntsuas. Qhov no pab kom txo qhov ua yuam kev los ntawm kev tsis xwm yeem cov khoom ntawm cov quav me.
Los ntawm kev ua raws li cov qib no ua tib zoo ntsuas, koj tuaj yeem ntsuas qhov nyuaj ntawm cov pob zeb ua haujlwm siv cov khoom siv hluav taws xob ua haujlwm nrog cov khoom siv hluav taws xob-ua haujlwm rockwell hardness tester.
