Ubunzima beVickers ngumgangatho wokuvakalisa ubulukhuni bezinto ezicetywayo nguBritish Robert L. Smith kunye noGeorge E. Sandland ngo-1921 eVickers Ltd. Le yenye indlela yokuvavanya ubulukhuni obulandela ukuqina kwe-Rockwell kunye neendlela zokuvavanya ubulukhuni beBrinell.
1 Umgaqo weVickers umvavanyi wobulukhuni:
Umvavanyi wobulukhuni beVickers usebenzisa umthwalo we-49.03 ~ 980.7N ukucinezela i-diamond intruder ye-cone-shaped diamond ene-angle edibeneyo ye-136 ° kumphezulu wezinto eziphathekayo.Emva kokuyigcina ixesha elithile, linganisa i-indentation diagonally.Ubude bomgca, uze ubale ixabiso lobulukhuni beVickers ngokwefomula.
2.Layisha uluhlu lwesicelo:
I-01: I-Vickers tester hardness enomthwalo we-49.03 ~ 980.7N ifanelekile ukulinganisa ubulukhuni beendawo zokusebenza ezinkulu kunye neengqimba ezinzulu zomhlaba;
I-02: Ubunzima obuncinci beVickers, umthwalo wokuvavanya <1.949.03N, ulungele ukulinganisa ubulukhuni bezinto zokusebenza ezincinci, izixhobo zokusebenza okanye iingubo;
I-03: Ubulukhuni be-Micro-Vickers, umthwalo wokuvavanya <1.961N, ilungele ukulinganisa ubulukhuni beentsimbi zetsimbi kunye neengqimba zomphezulu ezinqabileyo kakhulu.
Ukongeza, ixhotyiswe nge-indenter ye-Knoop, inokulinganisa ubulukhuni be-Knoop bezinto ezinqabileyo neziqinileyo ezifana neglasi, iiseramics, i-agate, kunye namatye anqabileyo okwenziwa.
3 Izinto ezilungileyo zokuvavanya ubulukhuni beVickers:
I-1) Uluhlu lokulinganisa lubanzi, ukusuka kwiintsimbi ezithambileyo ukuya kwii-ultra-hardness testers ukuya kwiintsimbi ezinzima kakhulu, kunye noluhlu lokulinganisa lusuka kumanani ambalwa ukuya kwamawaka amathathu eVickers.
2) I-indentation incinci kwaye ayilonakalisi i-workpiece.Ingasetyenziselwa ukuvavanya ubulukhuni bezixhobo zokusebenza ezinomphezulu wazo ongenakonakala.
3) Ngenxa yovavanyo oluncinci lwamandla, amandla ovavanyo oluncinci anokufikelela kwi-10g, ngoko ke inokubona izixhobo zokusebenza ezincinci nezincinci.
I-4 Ububi bomvavanyi wobulukhuni beVickers: Xa kuthelekiswa neendlela zokuvavanya ubulukhuni be-Brinell kunye ne-Rockwell, uvavanyo lwe-Vickers lobunzima luneemfuno zokugudiswa kwendawo yokusebenza, kwaye ezinye iindawo zokusebenza kufuneka ziphuculwe, ezichitha ixesha kunye nomsebenzi onzima;ulondolozo Umvavanyi wobulukhuni uchanekile noko kwaye awufanelekanga ukusetyenziswa kwiindibano zocweyo okanye kwindawo.Isetyenziswa kakhulu kwiilabhoratri.
5 Vickers ubulukhuni tester series
1) Umhloli wobulukhuni be-Economical Vickers
2) Digital display touch screen Vickers ubulukhuni tester
3) Umvavanyi wobulukhuni beVickers ngokuzenzekelayo
