Umvavanyi wobulukhuni beVickers wamkela i-diamond indenter, ecinezelwe kumphezulu wesampulu phantsi kovavanyo oluthile lwamandla. Ukukhupha amandla okuvavanya emva kokugcina ixesha elichaziweyo kunye nokulinganisa ubude be-diagonal ye-indentation, ngoko ixabiso lobunzima be-Vickers (HV) libalwa ngokwefomula.
Isiphumo sokucinezela intloko phantsi
- Ukusebenzisa amandla ovavanyo: Intloko yokucinezela inkqubo yinyathelo eliphambili lokudlulisa amandla ovavanyo olumiselweyo (njenge-1kgf, 10kgf, njl.) kumphezulu wezinto ezivavanyiweyo ngokusebenzisa i-indenter.
- Ukwenza i-indentation: Uxinzelelo lwenza ukuba i-indenter ishiye i-indenter ecacileyo yedayimani kumphezulu wezinto eziphathekayo, kwaye ubunzima bubalwa ngokulinganisa ubude be-diagonal ye-indent.
Lo msebenzi usetyenziswa ngokubanzi kuvavanyo lobulukhuni bezinto zetsimbi, amashiti amancinci, ii-coatings, njl., kuba inoluhlu olubanzi lwamandla ovavanyo kunye nokuhlenga okuncinci, okufanelekileyo ukulinganisa ngokuchanekileyo.
Njengoyilo oluqhelekileyo lwesakhiwo somvavanyi wobulukhuni beVickers (eyahlukileyo kuhlobo lokunyuka kwebhentshi), iingenelo "zokucinezela intloko phantsi" kukuqonda kokusebenza kwengqondo kunye nesakhiwo soomatshini, iinkcukacha ngolu hlobo lulandelayo,
1. Ukusebenza ngokulula ngakumbi, kuhambelana nemikhwa yoomatshini bomntu
Kwintloko ecinezela i-design down, umqhubi unokubeka ngokuthe ngqo isampuli kwi-workbench esisigxina, kwaye ugcwalise uqhagamshelwano kunye nokulayisha i-indenter ngentloko ezantsi, ngaphandle kokulungelelanisa rhoqo ukuphakama kwendawo yokusebenza. Le ngqiqo yokusebenza "phezulu-phantsi" ifaneleke ngakumbi kwimikhwa yokusebenza eqhelekileyo, ngakumbi inobubele kubaqalayo, inokunciphisa amanyathelo adinayo okubekwa kwesampulu kunye nokulungelelaniswa, ukunciphisa iimpazamo zokusebenza kwabantu.
2. Ukuzinza kokulayisha okunamandla, ukuchaneka komlinganiselo ophezulu
Intloko icinezela isakheko esisezantsi sikholisa ukusebenzisa indlela yokulayisha engqongqo (efana nezikrufu ezichanekileyo kunye neentsimbi zesikhokelo). Xa usebenzisa amandla ovavanyo, ukuqina kunye nesantya sokulayisha se-indenter kulula ukuyilawula, enokunciphisa ngokufanelekileyo ukungcangcazela koomatshini okanye i-offset. Ukufumana izinto ezichanekileyo ezifana namaphepha amancinci, iingubo, kunye namacandelo amancinci, oku kuzinza kunokuphepha ukuguqulwa kwe-indentation okubangelwa ukulayisha okungazinzanga kunye nokuphucula kakhulu ukuchaneka kokulinganisa.
3. Ukuguquguquka okubanzi kweesampuli
Iisampulu zobukhulu obukhulu, ubume obungaqhelekanga okanye ubunzima obunzima, idizayini yentloko-phantsi ayifuni ukuba i-workbench ithwale umthwalo ogqithiseleyo okanye izithintelo zokuphakama (i-workbench inokulungiswa), kwaye idinga kuphela ukuqinisekisa ukuba isampuli ingafakwa kwi-workbench, eyona nto "ukunyamezela" kwisampuli. Ukunyuka koyilo lwebhentshi yomsebenzi kunokukhawulwa ngumthwalo wokuthwala kunye nokuphakamisa i-stroke ye-workbench, ngoko ke kunzima ukuziqhelanisa neesampuli ezinkulu okanye ezinzima.
4. Ukuphindaphindwa komlinganiselo ongcono
Indlela yokulayisha ezinzileyo kunye nenkqubo yokusebenza efanelekileyo inokunciphisa impazamo ebangelwa ukungafani komsebenzi womntu (njengokuphambuka kokulungelelaniswa xa i-workbench iphakamisa). Xa ulinganisa isampuli efanayo amaxesha amaninzi, imeko yoqhagamshelwano phakathi kwe-indenter kunye neesampuli zihambelana ngakumbi, ukuphindaphinda kwedatha kungcono, kwaye ukuthembeka kwesiphumo kuphezulu.
Ukuqukumbela, umvavanyi we-Vickers we-headness-hardness tester uneenzuzo ezingaphezulu ngokulula, ukuzinza, kunye nokuguquguquka ngokulungisa ingqiqo yokusebenza kunye nesakhiwo soomatshini, kwaye ifaneleke ngokukodwa ukuvavanywa kwezinto ezichanekileyo, uvavanyo lweesampulu ezininzi okanye iimeko zokuvavanya rhoqo.
