Ukuqina kwe-Vickers kuyindinganiso yokuveza ubulukhuni bezinto ezihlongozwe u-British Robert L. Smith kanye no-George E. Sandland ngo-1921 e-Vickers Ltd. Lena enye indlela yokuhlola ubulukhuni elandela ukuqina kwe-Rockwell kanye nezindlela zokuhlola ubulukhuni be-Brinell.
1 Isimiso se-Vickers tester hardness:
Umhloli wokuqina we-Vickers sisebenzisa umthwalo ongu-49.03~980.7N ukuze ucindezele isingenisi sedayimane esiyisikwele esine-engeli efakiwe engu-136° endaweni ebonakalayo.Ngemva kokuyigcina isikhathi esithile, kala ukuhlehlisa ngokudayagonali.Ubude bomugqa, bese ubala inani lobulukhuni be-Vickers ngokuya ngefomula.
2.Layisha ibanga lesicelo:
01: I-Vickers tester hardness enomthwalo ongu-49.03~980.7N ifaneleka ukulinganisa ubulukhuni bezinto zokusebenza ezinkulu nezendlalelo ezijulile zomhlaba;
I-02: Ubulukhuni be-Vickers bomthwalo omncane, umthwalo wokuhlola <1.949.03N, ofanele ukukalwa kobulukhuni bezinto zokusebenza ezincane, izindawo zamathuluzi noma okokunamathela;
03: Ubulukhuni be-Micro-Vickers, umthwalo wokuhlola u-<1.961N, ofanele ukukalwa kobulukhuni bamatshe ensimbi nezingqimba ezingaphezulu ezincanyana kakhulu.
Ngaphezu kwalokho, ifakwe i-indenter ye-Knoop, ingakala ubulukhuni be-Knoop bezinto eziphukayo neziqinile njengengilazi, izitsha zobumba, i-agate, namatshe ayigugu okwenziwa.
3 Izinzuzo ze-Vickers tester hardness:
1) Ibanga lokulinganisa libanzi, kusukela kuzinsimbi ezithambile kuya kubahloli bokuqina kokuqina kuya kwezinsimbi eziqine kakhulu, futhi ububanzi bokulinganisa busukela kumanani ambalwa wokuqina we-Vickers ayizinkulungwane ezintathu.
I-2) I-indentation incane futhi ayilimazi i-workpiece.Ingasetshenziselwa ukuhlola ubulukhuni bezingxenye zokusebenza obuso bazo obungenakonakala.
3) Ngenxa yamandla ayo amancane okuhlola, amandla amancane okuhlola angafinyelela ku-10g, ngakho angakwazi ukubona izingcezu zokusebenza ezincane nezincane.
4 Ububi bomhloli wokuqina we-Vickers: Uma kuqhathaniswa nezindlela zokuhlola ukuqina kwe-Brinell kanye ne-Rockwell, ukuhlolwa kokuqina kwe-Vickers kunezidingo zokushelela kwendawo yokusebenza, futhi ezinye izinto zokusebenza zidinga ukupholishwa, okudla isikhathi futhi okukhandlayo;ukunakekelwa Isihloli sokuqina sinembile futhi asifanele ukusetshenziswa kuma-workshops noma endaweni.Isetshenziswa kakhulu kuma-laboratories.
5 Uchungechunge lokuhlola ubulukhuni be-Vickers
1) Umhloli wobulukhuni be-Economical Vickers
2) Digital display screen touch screen Vickers ubulukhuni umhloli
3) Umhloli wobulukhuni be-Vickers ozenzakalelayo ngokugcwele
Isikhathi sokuthumela: Dec-15-2023
