Nigute ushobora guhitamo ikizamini cyo kugerageza gupima ingero?

1) Ikizamini cya Rockwell gishobora gukoreshwa mugupima ubukana bwurukuta rwicyuma?

Ibikoresho byo kwipimisha ni SA-213M T22 umuyoboro wibyuma ufite diameter yo hanze ya 16mm nubugari bwurukuta rwa 1.65mm. Ibisubizo by'ibizamini by'ikizamini cya Rockwell ni ibi bikurikira: Nyuma yo gukuraho igipimo cya oxyde na decarburisation hejuru yicyitegererezo hamwe na gride, icyitegererezo gishyirwa kumurimo wakozwe na V, kandi ikizamini cya HRS-150S cyifashishwa mu gupima ubukana bwa Rockwell hejuru yacyo gifite umutwaro wa 980.7N. Nyuma yikizamini, birashobora kugaragara ko urukuta rwumuyoboro wibyuma rufite ihinduka rito, kandi igisubizo nuko agaciro gakomeye ka Rockwell gapimwe kari hasi cyane, bikavamo ikizamini kitemewe.

Ukurikije GB / T 230.1-2018 «Ibikoresho Byuma Byibizamini bya Rockwell Igice cya 1: Uburyo bwikizamini», ubukana bwa Rockwell ni 80HRBW naho uburebure bwikitegererezo ni 1.5mm. Umubyimba wicyitegererezo No 1 ni 1.65mm, ubunini bwurwego rwa decarburize ni 0,15 ~ 0,20mm, naho ubunini bwikitegererezo nyuma yo gukuraho igipande cya decarburize ni 1.4 ~ 1.45mm, kikaba cyegereye umubyimba muto wicyitegererezo cyerekanwe muri GB / T 230.1-2018. Mugihe cyikizamini, kubera ko nta nkunga iri hagati yicyitegererezo, bizatera ihinduka rito (rishobora kutarebwa nijisho), bityo agaciro gakomeye ka Rockwell kari hasi.

2) Nigute wahitamo igeragezwa ryikigereranyo cyo gupima ibyuma:

Nyuma y ibizamini byinshi hejuru yuburemere bwimiyoboro yicyuma, isosiyete yacu yageze kumyanzuro ikurikira:

1.

2.

3. Uburyo bwo guhindura ubukana bwa Vickers bwapimwe nubukomere bwa Rockwell nyuma yo gushiramo no gusya icyitegererezo cyicyuma cyicyitegererezo kirasa neza.
