Intambwe imwe y'ubuyobozi bwo guhitamo ubwoko bukwiye
Hitamo ukurikije ingano eshanu: ingano y'ibikoresho, ibikoresho, ingano y'ubukana, ibisabwa mu buryo bunonosoye, n'imiterere y'ikoreshwa. Nta mpamvu yo guhangayika, kurikiza gusa ubuyobozi hanyuma ufate icyemezo.
I. Ubwa mbere, shyira mu byiciro bitatu by'ingenzi by'ibikoresho bipima ubukana
1. Ikizamini cya Rockwell Ikizamini (HRC / HRB / HRA)
Bikwiriye: icyuma cyazimye, icyuma gishyushye, ibyuma bitwara imizigo, ibikoresho, ibice bishyushye
Ibyiza: gukoresha neza cyane, bikoreshwa cyane mu bipimo ngenderwaho by'igihugu, ibikoresho bisanzwe byo kugenzura ubuziranenge bw'uruganda
Ibibi: ugomba gufata ingero / ubwoko bwa mudasobwa, ibice binini ntibishobora kwimurwa cyangwa gupimwa aho bikorerwa
Icyo gupima:
HRC: icyuma gikomeye cyane cyazimye (ibyuma, ibikoresho, ibikoresho)
HRB: umuringa, aluminiyumu, icyuma gikoresha karubone nkeya, icyuma cyoroshye
2. Igipimo cy'ubukomere bwa Brinell (HB)
Bikwiriye: icyuma gishongeshejwe, icyuma gishongeshejwe, aluminiyumu, umuringa, ibice bicuzwe
Ibyiza: gupfundikanya igice kinini, ni byiza cyane ku bikoresho bifite ubugari buto n'ibidahuye
Ingaruka mbi: gupfundikanya cyane, kwangiza, ubushobozi buke, bikwiye gupimwa ahantu hakorerwa ubushakashatsi muri laboratwari
3. Igipimo cy'ubukomere bwa Leeb (ishobora kwimurwa HL kuri HRC/HB/HV)—Igipimo cy'ubukomere bwa Leeb cya YY251D
Bikwiriye: ibice binini, igeragezwa ry’aho hantu, ibice bidashobora gusenywa, ibumba riremereye, imizingo, imigozi
Ibyiza: ikoreshwa mu ntoki kandi igendanwa, ntiyangiza, nta mpamvu yo gufata ingero, ishobora gukoreshwa mu myanya ihagaze, itambitse, cyangwa hejuru
Ibibi: ubuziranenge buri hasi gato ugereranyije na desktop Rockwell, amakosa akomeye ku bice bito n'ibinini bito
II. Hitamo ukurikije ikoreshwa ry'ibikenewe (bikunze gukoreshwa cyane)
Urugero rwa 1: Laboratwari yo mu kigo, igenzura ry'ubuziranenge bw'ibikoresho byinjira / ubushyuhe, hakenewe ubushishozi bwinshi Hitamo icyuma gipima ubukana bwa Rockwell cyo kuri mudasobwa
Ikoreshwa cyane mu nganda zikora ibikoresho rusange, zikora ibikoresho byo mu bwoko bwa "die-fie", n'izitunganya ubushyuhe.
Icyitegererezo cya 2: icyuma gikozwe mu cyuma, gucukura, aluminium alloy, ibice by'icyuma bicuzwe mu cyuma
Hitamo icyuma gipima ubukana bwa Brinell
Urugero rwa 3: ibice binini bidashobora kwimurwa, igeragezwa ry’aho hantu, ibumba / imizingo / imigozi minini Ugomba guhitamo ikizamini cyo gupima ubukana bwa Leeb gitwarwa
Icyitegererezo cya 4: ibice bito, impapuro nto, ubukana bw'ubuso bw'ibice bya kaburimbo n'ibice bya nitride Hitamo igikoresho gipima ubukana bwa Vickers (HV)
Bikwiriye: impapuro zoroshye, impande z'ibikoresho, irangi, ibice bikomeye.
III. Hitamo ukurikije ubunini/ingano y'ibikoresho
Ibice binini, biremereye kandi bitimukanwa → Leeb
Ingero zisanzwe, ibice bito, zishobora gushyirwa kuri desktop → Rockwell
Ibice bito cyane < 3mm, ubuso bukomereye → Vickers
Ibikoresho byo gucukura, ibikoresho bidahuye → Brinell
IV. Hitamo ukurikije urwego rw'ubukomere
Ibikoresho byoroshye: aluminiyumu, umuringa, icyuma gikoresha karuboni nkeya → HRB / HB
Ubukomere buringaniye: icyuma cyazimye kandi gishyushye, icyuma cyubatswe → HRC / HB
Ubukomere bwinshi: ibikoresho byazimye, ibikoresho, imiringoti → HRC / HV
Uduce tw'ubuso duto cyane / utw'ibice bya kaburimbo → HV Vickers
