Kuongororwa kweKusarudzwa kweRudzi rweMidziyo yeKuomesa Kuoma kweMabasa Makuru neAnorema

Sezvazvinozivikanwa, nzira yega yega yekuedza kuomarara—ingave ichishandisa Brinell, Rockwell, Vickers, kana vanoedza kuomarara vanotakurika veLeeb—ine zvipingamupinyi zvayo uye hapana inoshanda zvachose. Kune maworkpiece makuru, anorema ane saizi dzisina kurongeka sedzinoratidzwa mumuenzaniso uri pazasi, vanoedza kuomarara vanotakurika veLeeb parizvino vanoshandiswa zvakanyanya munzira dzakawanda dzekuedza kudzora kuomarara kwavo.

Chiyedzo cheLeeb hardness chinoshandisa nzira yekuedza ine simba, uye pane zvinhu zvakawanda zvinokanganisa kururama kwekuyedzwa kwacho kwekuoma, zvakaita se elastic modulus yezvinhu, kupera kwe indenter ball, kuomarara kwenzvimbo yebasa, radius yekukombama, uye kudzika kwe surface hardening layer. Zvichienzaniswa nenzira dzekuyedza dzakasimba dzeBrinell, Rockwell, naVickers hardness testers, kukanganisa kwacho kwekuyedza kwakakura zvikuru. Saka, kana kunyatsorurama kuchidikanwa pakuyedzwa kwekuoma, tinofanira kusarudza sei chiyedzo chekuoma?

Munguva yekuedza michina mikuru uye inorema yakadai uchishandisa michina yakajairika yekuedza kuomarara, kurodha michina yekushanda isati yaedzwa, kurodha nekuburitsa mudziyo wekuedza kuomarara panguva yekuedza, uye kuburitsa michina yekushanda mushure mekuedza zvese izvi zvichaunza basa rakakura pakushanda. Saka, tinofanira kusarudza sei mudziyo wekuedza kuomarara?

Vaviri vari pamusoro pevanoedza kuomarara vane chimiro chemusoro unosimudza vanokurudzirwa kuti vapedze maitiro ese ekuyedza, senge Rockwell hardness tester yedu yakagadzirwa padenga guru remhando yeRockwell online HRZ-150GE uye Rockwell hardness tester SCR3.0 inogadzirwa nedesktop head up&down.

Iyi mhinduro yekuyedza kuomarara inogonesa kuyedza kuomarara kweRockwell zvichienderana nemitemo yepasi rose yekuyedza kuomarara (senge ISO 6506-1:2014 uye ISO 6507-1:2018). Saizvozvowo, kune kuyedza kuomarara kweVickers naBrinell, chimiro chekusimudza otomatiki chemusoro wekuyedza chinogonawo kuitwa. Panguva iyi, inosangana nezvinodiwa zvekuyedza kwakanyatsojeka kwezvinhu zvinorema uye kugadzirwa kwakanaka.
