Yuav ua li cas txhawm rau ntsuas qhov tseeb ntawm Portable Hardness Tester

Kev ntsuas tsis tu ncua, ib puag ncig kev ua haujlwm zoo ib puag ncig, kev npaj tsim nyog, thiab rov ntsuas dua ntawm ntau qhov chaw nyob rau hauv qhov chaw ruaj khov yog cov txheej txheem tseem ceeb rau kev lees paub qhov ntsuas qhov tseeb ntawm lub zog hardness tester. Kev ntsuam xyuas ntawm kev kho cua sov zoo ntawm cov khoom siv H13 tuaj yeem cuam tshuam los ntawm kev nyeem ntawv hloov pauv los ntawm kev saib xyuas hauv txhua theem.

 

1. Calibration thiab tu cov cuab yeej

Ua ntej-siv Calibration: Ua ntej txhua qhov kev sim, paub meej tias qhov ntsuas qhov yuam kev tsawg dua lossis sib npaug rau ± 1 HRC ntawm tus qauv hardness thaiv;

Kev soj ntsuam tsis tu ncua: Txhawm rau lav kom ntev - lub sijhawm ruaj khov, xa cov cuab yeej mus rau lwm qhov chaw ua haujlwm - tog rau kev ntsuas txhua peb lub hlis.

Kev Tshawb Fawb Kev Tshawb Fawb: Txhawm rau tiv thaiv cov ntaub ntawv drift los ntawm kev ua haujlwm tsis ua haujlwm, xyuas kom tus neeg raug cuam tshuam tsis muaj kev hnav lossis jamming.

Tswv yim tswv yim: Txhawm rau kom muaj kev vam meej, xaiv Leeb hardness tester (xws li HLN-200) nrog rau qhov kev ceeb toom tsis siv neeg calibration.

 

2. Tswj kev ntsuas ib puag ncig

Appropriate Temperature: To avoid material softening or equipment failure, avoid taking measurements in high-temperature (>50 degree) lossis qis-kub (<5°C) conditions.

Tiv thaiv kev co thiab cuam tshuam los ntawm kev zam qhov chaw ntawm kev co xws li stamping thiab forging. Cov khoom siv yuav tsum tau tiv thaiv los yog muab tua nyob rau hauv cov chaw uas muaj hluav taws xob siab.

Workpiece Stability: Txhawm rau kom tsis txhob txav mus los ntawm qhov cuam tshuam, uas tuaj yeem hloov pauv tus nqi rov qab, me me lossis nyias -cov khoom ua haujlwm phab ntsa yuav tsum tau ceev thiab kho.

Piv txwv li, Wuhan- raws li kev lag luam tau ntsib qhov xwm txheej uas H13 nozzle hardness qhov tseem ceeb feem ntau yog 2-3 HRC qis dua li qhov xav tau vim qhov ntsuas ncaj qha hauv thaj chaw kub kub ze rau lub qhov cub tawg. Kev ntsuam xyuas rov pib dua li qub tom qab txias.

 

3. Txoj kev ua haujlwm tsim nyog

Cov txheej txheem

Cov kauj ruam tseem ceeb

Lub hom phiaj

Nto Kho

Tshem tawm cov roj stains thiab oxide nplai los ntawm xuab zeb nrog cov ntawv xuab zeb kom txog thaum nws muaj lub ci ci.

Ua kom pom tseeb ntawm cov xwm txheej saum npoo uas cuam tshuam kev sib cuam tshuam.

Kev faib cov ntsiab lus ntsuas

Rau txhua daim, xaiv peb mus rau tsib tus qauv ua haujlwm (piv txwv li, nruab nrab, ntug, thickness ciam teb).

Boost tus sawv cev ntawm cov ntaub ntawv.

Txoj kev ntsuas

Xam qhov nruab nrab tom qab noj peb qhov ntsuas ib qho taw tes.

Cov ntaub ntawv uas nyob ib sab yuav tsum sib nrug tsawg kawg 3 mm sib nrug. Txiav ntawm qhov yuam kev random.

Kev ntes cov ntaub ntawv

Hauv lub sijhawm tiag tiag, nco ntsoov thiab suav cov qauv sib txawv thiab ntau yam.

Paub txog qhov hloov pauv tsis zoo sai sai.

Kev lees txais Standard: Batch nruab nrab ntawm 48 thiab 52 HRC, ib yam khoom hardness tsawg dua los yog sib npaug rau 2 HRC.

 

4. Kev txheeb xyuas thiab txheeb xyuas cov ntaub ntawv

Rov ntsuas cov ntaub ntawv cov ntsiab lus nrog qhov sib txawv tseem ceeb tam sim ntawd kom pom seb lawv puas yog qhov tshwm sim ntawm kev ua haujlwm tsis raug yog hu ua qhov txawv txav rov ua dua.

Hla- pov thawj: Siv lub ntsiav tshuaj Rockwell hardness tester, ua piv txwv cov haujlwm tseem ceeb thiab xa mus rau qhov chaw kuaj xyuas kom pom tseeb.

Cov ntaub ntawv khaws cia: Txhawm rau kom muaj txiaj ntsig zoo, khaws lub sijhawm sim, tus neeg, tus lej ntsuas, thiab cov ntaub ntawv qub. "Kev ntsuas kom raug, tswj ib puag ncig, kev ua haujlwm tau zoo, thiab khaws cov ntaub ntawv" yog tag nrho cov kev cai tseem ceeb ntawm kev nyab xeeb.
