Hauv kev tsim cov khoom siv kho vajtse, qhov nyuaj yog qhov qhia tseem ceeb. Piv txwv li, saib qhov seem hauv daim duab. Peb tuaj yeem siv lub Rockwell hardness tester los ua qhov kev sim hardness.
Peb lub tshuab ntsuas Rockwell hardness uas siv hluav taws xob yog ib qho cuab yeej siv tau zoo heev rau lub hom phiaj no. Cov txheej txheem sim ntawm lub tshuab ntsuas hardness no yooj yim heev thiab nkag siab tau yooj yim.
Nws siv lub zog ntawm 150kgf thiab siv lub pob zeb diamond indenter rau qhov kev sim. Tom qab qhov kev sim tiav lawm, qhov ntsuas qhov nyuaj yog raws li HRC Rockwell hardness scale. Txoj kev siv Rockwell hardness tester no tau lees paub dav thiab siv hauv kev lag luam rau nws qhov tseeb thiab yooj yim. Nws ua rau cov chaw tsim khoom ntsuas qhov nyuaj ntawm cov khoom siv kho vajtse kom raug, kom ntseeg tau tias cov khoom ua tau raws li cov qauv zoo. Txawm hais tias nws yog nyob rau hauv kev tsim cov khoom siv kho tshuab, cov khoom siv kho vajtse, lossis lwm yam kev lag luam cuam tshuam, qhov kev kuaj pom qhov nyuaj yog qhov tseem ceeb rau kev ua haujlwm thiab kev pabcuam ntawm cov khoom.
Peb lub tshuab ntsuas qhov nyuaj tsis yog tsuas yog muab cov txiaj ntsig kev sim txhim khu kev qha xwb tab sis kuj ua kom yooj yim rau cov txheej txheem kev sim, uas ua rau muaj kev ua haujlwm zoo ntawm kev tswj xyuas zoo hauv cov txheej txheem tsim khoom ntawm cov khoom siv kho vajtse.
Nov yog cov kauj ruam kev xeem ntxaws ntxaws rau kev siv lub zog hluav taws xob-siv cov zaub digital Rockwell hardness tester ntawm Shandong Shancai Company los ntsuas qhov nyuaj ntawm cov khoom siv kho vajtse raws li txoj kev kuaj Rockwell hardness rau cov khoom siv hlau:
- Npaj cov tester thiab cov qauv kuaj:
1.1Xyuas kom tseeb tias lub tshuab ntsuas zog hluav taws xob Rockwell hardness tester tau raug kho kom zoo thiab ua haujlwm tau zoo. Xyuas txhua qhov kev sib txuas thiab kev ua haujlwm, xws li lub hwj chim, cov zaub digital, thiab lub kaw lus siv zog.
1.2Xaiv cov qauv khoom siv kho vajtse uas yuav raug kuaj. Xyuas kom tseeb tias qhov chaw ntawm cov qauv huv si, tsis muaj av qias neeg, roj, lossis cov txheej oxide. Yog tias tsim nyog, txhuam qhov chaw kom tau txais thaj chaw kuaj du thiab tiaj tus.
2. Nruab lub indenterXaiv lub pob zeb diamond indenter uas tsim nyog raws li qhov yuav tsum tau ua ntawm kev sim. Txhawm rau ntsuas qhov nyuaj ntawm HRC Rockwell hardness scale, ntsia lub pob zeb diamond indenter rau hauv lub tester lub indenter holder. Xyuas kom tseeb tias lub indenter tau ruaj khov thiab sib dhos kom raug.
3. Teem lub zog simKho lub tshuab kuaj kom teeb tsa lub zog kuaj rau 150kgf. Qhov no yog lub zog kuaj txheem rau HRC nplai. Paub tseeb tias qhov teeb tsa lub zog yog qhov tseeb los ntawm lub vaj huam sib luag tswj hwm ntawm lub tshuab kuaj lossis cov txheej txheem hloov kho.
4. Tso cov qauvMuab cov qauv kuaj tso rau ntawm lub qhov ntsuas ntawm lub tshuab kuaj. Siv cov khoom siv lossis cov cuab yeej tsim nyog los xyuas kom meej tias cov qauv kuaj tau muab tso rau qhov chaw ruaj khov thiab ruaj khov, thiab qhov chaw kuaj tau ntsug rau lub axis ntawm lub tshuab kuaj.
5. Lub tshuab ntsuas qhov nyuaj yuav thauj khoom, nyob, thiab tshem tawm
6.Nyeem tus nqi hardnessThaum lub indenter raug tshem tawm tag, lub vijtsam digital ntawm lub tester yuav qhia qhov ntsuas qhov nyuaj ntawm HRC Rockwell hardness scale. Sau cov nqi no kom raug.
7. Rov ua qhov kev xeem dua (yog tias tsim nyog)Yog xav tau cov txiaj ntsig tseeb dua, nws raug nquahu kom rov ua cov kauj ruam saum toj no ntawm ntau qhov chaw sib txawv ntawm qhov chaw ntawm cov qauv thiab xam tus nqi nruab nrab ntawm ntau qhov kev ntsuas. Qhov no pab txo qhov yuam kev uas tshwm sim los ntawm cov khoom siv tsis sib xws ntawm qhov chaw ntawm cov qauv.
Los ntawm kev ua raws li cov kauj ruam no kom zoo zoo, koj tuaj yeem ntsuas qhov nyuaj ntawm cov khoom siv kho vajtse siv txoj kev ntsuas Rockwell hardness nrog lub zog hluav taws xob uas siv cov duab digital Rockwell hardness tester.
