Indlela yokuvavanya ubulukhuni beVickers kunye nezilumkiso

1 Amalungiselelo phambi kovavanyo

I-1) I-hardness tester kunye ne-indenter esetyenziselwa uvavanyo lobunzima beVickers kufuneka ihambelane nemimiselo ye-GB/T4340.2;

2) Ubushushu begumbi kufuneka bulawuleke ngokubanzi phakathi koluhlu lwe-10 ~ 35 ℃. Kwiimvavanyo ezineemfuno ezichaneke kakhulu, kufuneka ilawulwe ku-(23±5)℃.

2 iisampulu

1) Umphezulu wesampuli kufuneka ube tyaba kwaye ugudileyo. Kucetyiswa ukuba uburhabaxa besampulu yomphezulu kufuneka buhlangabezane neemfuno: Elona xabiso liphezulu loburhabaxa bomphezulu iparamitha: Isampulu yobulukhuni beVickers 0.4 (Ra)/μm; umthwalo omncinci isampuli yobulukhuni beVickers 0.2 (Ra) / μm; micro Vickers isampulu yobulukhuni 0.1 (Ra)/μm

I-2) Umthwalo omncinci weVickers kunye neesampuli zeVickers ezincinci, kucetyiswa ukuba ukhethe ukupholisa okufanelekileyo kunye ne-electrolytic polishing kunyango lomphezulu ngokohlobo lwezinto eziphathekayo.

3) Ubukhulu besampulu okanye umaleko wovavanyo kufuneka ubuncinci amaxesha angama-1.5 ubude be-diagonal ye-indentation.

I-4) Xa usebenzisa umthwalo omncinci kunye ne-Vickers encinci yokuvavanya, ukuba isampuli incinci kakhulu okanye ingaqhelekanga, isampuli kufuneka ifakwe okanye igxininiswe ngesigxina esikhethekileyo ngaphambi kokuvavanya.

3Indlela yokuvavanya

I-1) Ukukhethwa kwamandla okuvavanya: Ngokobunzima, ubukhulu, ubukhulu, njl. .

umfanekiso 2

2) Ixesha lokuvavanya amandla ovavanyo: Ixesha ukususela ekuqaleni kokusetyenziswa kwamandla ukuya ekugqityweni kwesicelo esipheleleyo sovavanyo kufuneka sibe phakathi kwe-2 ~ 10 s. Kumthwalo omncinci weVickers kunye ne-Vickers micro test hardness, i-indenter ehla isantya akufanele idlule i-0.2 mm / s. Ixesha lovavanyo lokubamba amandla yi-10 ~ 15 s. Kwizinto ezithambileyo ngakumbi, ixesha lokubamba linokwandiswa, kodwa impazamo kufuneka ibe ngaphakathi kwe-2.

3) Umgama ukusuka kumbindi we-indent ukuya kumda wesampuli: Insimbi, ubhedu kunye ne-alloys zethusi kufuneka zibe ubuncinane amaxesha angama-2.5 ubude be-diagonal ye-indent; isinyithi esikhanyayo, i-lead, i-tin kunye ne-alloys yazo kufuneka ibe ubuncinane amaxesha ama-3 ubude be-diagonal ye-indentation. Umgama phakathi kwamaziko amabini ama-indentations akufutshane: kwintsimbi, ubhedu kunye ne-alloys zethusi, kufuneka kube ubuncinane amaxesha ama-3 ubude bomgca we-diagonal we-stop mark; kwiintsimbi ezikhanyayo, ilothe, itoti kunye neealloyi zazo, kufuneka zibe bubude obuphindwe ka-6 ubude bomgca wediagonal we-indentation.

4) Ukulinganisa i-arithmetic mean yobude be-diagonal ezimbini ze-indentation, kwaye ufumane ixabiso le-Vickers lobulukhuni ngokwetafile, okanye ubale ixabiso lobulukhuni ngokwefomula.

Umahluko kubude bee-diagonal ezimbini ze-indentation kwi-plane akufanele idlule i-5% yexabiso eliphakathi kwee-diagonals. Ukuba idlula, kufuneka ibhalwe kwingxelo yovavanyo.

I-5) Xa uvavanya kwisampulu yomhlaba ogobileyo, iziphumo kufuneka zilungiswe ngokwetafile.

6) Ngokubanzi, kucetyiswa ukuba uxele amaxabiso ovavanyo lobunzima bamanqaku amathathu kwisampula nganye.

4 Ulwahlulo lwabavavanyi bobulukhuni beVickers

Kukho iintlobo ezi-2 ezisetyenziswa ngokuqhelekileyo abavavanyi bobulukhuni beVickers. Oku kulandelayo sintshayelelo kusetyenziso oluqhelekileyo lomvavanyi wobulukhuni beVickers:

1. Uhlobo lomlinganiselo wamehlo;

2. Uhlobo lomlinganiselo wesoftware

Ulwahlulo 1: Uhlobo lomlinganiselo wamehlo Amanqaku: Sebenzisa i-eyepiece ukulinganisa. Ukusetyenziswa: Umatshini wenza (i-diamond ◆) indentation, kwaye ubude be-diagonal yedayimani bulinganiswa nge-eyepiece ukufumana ixabiso lobunzima.

UHlelo 2: Uhlobo lomlinganiselo wesoftware:Iimpawu: Sebenzisa isoftware yobulukhuni ukulinganisa; kulula kwaye kulula emehlweni; inokulinganisa ubulukhuni, ubude, gcina imifanekiso yokuhlenga, ingxelo yokukhupha, njl.

5Ukuhlelwa kweSoftware: Iinguqulelo ezi-4 ezisisiseko, inguqulelo yolawulo lwe-turret oluzenzekelayo, uguqulelo oluzenzekelayo, kunye noguqulelo oluzenzekelayo ngokupheleleyo.

1. Uguqulelo olusisiseko

Unokulinganisa ubulukhuni, ubude, ukugcina imifanekiso yokuhlenga, iingxelo zokukhupha, njl. njl.;

I-2.Lawula i-software ye-turret version ye-othomathikhi inokulawula i-turret tester turret, njenge-lens yenjongo, i-indenter, ukulayisha, njl.;
I-3.Semi-automatic version kunye netafile yokuvavanya i-XY yombane, ibhokisi yokulawula iqonga le-2D; Ukongeza kwi-automatic turret version function, isoftware inokuseta izithuba kunye namanqaku, ukuchaphaza okuzenzekelayo, ukulinganisa okuzenzekelayo, njl.;
I-4.Uguqulelo oluzenzekelayo oluzenzekelayo kunye netafile yokuvavanya i-XY yombane, ibhokisi yokulawula i-platform ye-3D, i-Z-axis focus; Ukongeza kwi-semi-automatic version function, isofthiwe nayo inomsebenzi wokugxila we-Z-axis;

6Indlela yokukhetha iVickers efanelekileyo yokuvavanya ubulukhuni

Ixabiso le-Vickers tester hardness liya kuhluka ngokuxhomekeke kuqwalaselo kunye nomsebenzi.

1. Ukuba ufuna ukukhetha elona xabiso liphantsi, ungakhetha:

Isixhobo esinesikrini esincinci se-LCD kunye negalelo le-diagonal ngesandla nge-eyepiece;

2. Ukuba ufuna ukukhetha isixhobo esingabizi kakhulu, ungakhetha:

Izixhobo ezinesikrini esikhulu se-LCD, i-eyepiece ene-encoder yedijithali, kunye nomshicileli owakhelwe ngaphakathi;

3. Ukuba ufuna isixhobo esikumgangatho ophezulu, ungakhetha:

Izixhobo kunye nesikrini sokuthinta, i-sensor evaliweyo, i-eyepiece eneprinta (okanye i-USB flash drive), i-worm gear lifting screw, kunye ne-encoder yedijithali;

4. Ukuba ucinga ukuba kuyadinisa ukulinganisa ngeso, ungakhetha:

Ixhotyiswe ngenkqubo ye-CCD yobulukhuni bokucwangcisa umfanekiso, ukulinganisa kwikhompyutheni ngaphandle kokujonga i-eyepiece, elula, enembile, kwaye ekhawulezayo. Unokwenza iingxelo kwaye ugcine imifanekiso ye-indentation, njl.

5. Ukuba ufuna ukusebenza okulula kunye ne-automation ephezulu, ungakhetha:

Umvavanyi wobulukhuni ozenzekelayo weVickers kunye nomvavanyi wobulukhuni obuzenzekelayo beVickers

Iimpawu: seta izithuba kunye nenani lamanqaku, ngokuzenzekelayo kwaye ngokuqhubekayo ichaphaza, kunye nokulinganisa ngokuzenzekelayo.
