Uhlelo lokuhlola ubulukhuni be-Vickers

Umsuka womhloli wobulukhuni beVickers

Ubulukhuni bukaVickers buyindlela ejwayelekile yokumelela ubulukhuni bezinto eziphakanyiswe nguRobert L. Smith noGeorge E. Sandland ngo-1921 kwaVickers Ltd. Lena enye indlela yokuhlola ubulukhuni elandela izindlela zokuhlola ubulukhuni bukaRockwell noBrinell.

Isimiso somhloli wobulukhuni be-Vickers:

Isihloli sokuqina kwe-Vickers sisebenzisa umthwalo ongu-49.03 ~ 980.7N ukucindezela idayimane eliyindilinga eliyisikwele eline-engeli ehlobene engu-136 ° ebusweni bento. Ngemva kokuyibamba isikhathi esibekiwe, inani lokuqina kwe-Vickers libalwa ngokulinganisa ubude obuqondile bokugoba nokusebenzisa ifomula.

Ububanzi bokusetshenziswa komthwalo bezinhlobo ezintathu ezilandelayo ze-Vickers (ama-micro Vickers):

Isihloli sokuqina kwe-Vickers esinomthwalo ongu-49.03 ~ 980.7N sifanelekela ukulinganisa ubulukhuni bezinto zokusebenza ezinkulu kanye nezendlalelo ezijulile.

Ubulukhuni be-Vickers obuphansi, umthwalo wokuhlola<1.949.03N, obufanele ukulinganiswa kobulukhuni bezinto zokusebenza ezincane, izindawo zamathuluzi, noma izembozo;

Ubulukhuni be-Micro Vickers, umthwalo wokuhlola <1.961N, kufanelekile ekulinganisweni kobulukhuni be-foil yensimbi kanye nezendlalelo zobuso ezincane kakhulu.

Ngaphezu kwalokho, ifakwe i-Knoop indenter, ingalinganisa ubulukhuni be-Knoop bezinto ezibuthakathaka neziqinile njengengilazi, izinto zobumba, i-agate, namatshe ayigugu okwenziwa.

Izinzuzo zomhloli wokuqina we-Vickers:

1. Ububanzi bokulinganisa bubanzi, kusukela ezinsimbini zesofthiwe kuya ezinsimbini eziqinile kakhulu, futhi bungatholakala, kusukela kumanani obulukhuni be-Vickers ambalwa kuya kwayizinkulungwane ezintathu.

2. Ukugoba kuncane futhi akulimazi i-workpiece, engasetshenziswa ekuhlolweni kobulukhuni kuma-workpiece angonakaliswa ebusweni be-workpiece

3. Ngenxa yamandla ayo amancane okuhlola, amandla amancane okuhlola angafinyelela ku-10g, okungabona ezinye izinto zokusebenza ezincane nezincane

Okubi nge-Vickers hardness tester:

Uma kuqhathaniswa nezindlela zokuhlola ubulukhuni beBrinell neRockwell, ukuhlolwa kobulukhuni beVickers kunezidingo zokushelela kobuso bento yokusebenza. Ezinye izinto zokusebenza zidinga ukupholishwa, okuthatha isikhathi futhi kudinga umsebenzi omningi.

Izihloli zokuqina kwe-Vickers zinembile kakhulu futhi azifanele ukusetshenziswa ezindaweni zokusebenzela noma endaweni, futhi zisetshenziswa kakhulu emalabhorethri.

Uchungechunge lokuhlola ubulukhuni beShandong Shancai Vickers (isithombe sikaWang Songxin)

1. Isihloli sokuqina kwe-Economic Vickers

2. Isibonisi sedijithali kanye nesivivinyo sokuqina kwesikrini sokuthinta i-Vickers

3. Isihloli sokuqina kwe-Vickers esizenzakalelayo ngokuphelele
