Nigute ushobora kugenzura niba testers ikomeye ikora bisanzwe?
1.Gusuzugurwa gukomeye bigomba kugenzurwa byuzuye rimwe mukwezi.
2. Ikibanza cyo Kwishyiriraho Ikizamini gikomeye kigomba kubikwa ahantu hahana, kunyeganyega kandi kitari ruswa, kugirango tumenye neza ko igikoresho cyo gupima no gushikama no kwizerwa by'agaciro mugihe cyubushakashatsi.
3. Iyo ikizamini gikomeye gikora, nticyemewe gukora ku buso bw'icyuma kugirango gipimirwe kugirango wirinde neza ibipimo bidahwitse cyangwa byangiza diyama
4. Mugihe cyo gukoresha diyama, birakenewe kugenzura ubuso burangiye mubyumba rimwe mumwaka. Nyuma ya buri gipimo, isonter igomba gusubizwa mumasanduku idasanzwe yo kubika.
Gukomera Tester ingamba:
Usibye ingamba zidasanzwe iyo ukoresheje ibikorwa bitandukanye bikomeye, hari ibibazo bimwe bigomba kwishyurwa, biri hano hepfo:
1. Ikizamini cyo gukomera ubwacyo kizatanga ubwoko bubiri bw'amakosa: imwe ni ikosa ryatewe no kuroba no kugenda kw'ibice byayo; Irindi ni ikosa ryatewe na parameter ikomeye irenga ibipimo byagenwe. Ku ikosa rya kabiri, tessest yo gukomera igomba guhinduka hamwe na stricle isanzwe mbere yo gupima. Kuberako kalibrasi ibisubizo bya rockwell gukomera, itandukaniro ryujuje ibisabwa muri ± 1. Agaciro gukosorwa karashobora gutangwa ku gaciro gahamye hamwe nitandukaniro muri ± 2. Iyo itandukaniro riri hanze yurwego rwa ± 2, ni ngombwa guhindura no gusana ikizamini cyo gukomera cyangwa guhinduka mubundi buryo bwo gupima.
Buri gipimo cya rockwell gifite urugero rwa porogaramu ya de face, igomba gutoranywa neza ukurikije amabwiriza. Kurugero, mugihe ubutoni burenze HRB100, igipimo cya HRC kigomba gukoreshwa mugupima; Iyo gukomera biri munsi ya HRC20, igipimo cya HRB kigomba gukoreshwa mugupima. Kuberako ubwishingizi bwubwenge bukomeye ari bubi mugihe intera ndende irenze, kandi agaciro katoroshye ni udakwiye, ntabwo bikwiriye gukoreshwa. Ubundi buryo bwo gupima no gupima nabwo bufite amahame yo muri kalibration. Ikibanza gisanzwe cyakoreshwaga kugirango gihagarike testers ikomeye ntigishobora gukoreshwa kumpande zombi, kuko ubunini bwimpande zisanzwe nuruhande rwinyuma ntabwo byanze bikunze ari kimwe. Mubisanzwe biteganijwe ko guhagarika bisanzwe bifite ishingiro mugihe cyumwaka umwe uhereye kuri kalibrasi itariki.
2. Iyo usimbuze indente cyangwa anvil, witondere gusukura ibice. Nyuma yo kuyihindura, gerageza inshuro nyinshi hamwe nigiti cyimbaraga runaka kugeza agaciro gakomeye wabonetse kabiri kumurongo ni kimwe. Intego ni ugukora indente cyangwa anvil hamwe nigice cya contact cyimashini yipimisha gukanda neza kandi muburyo bwiza, kugirango utagirire ingaruka zukuri kubisubizo byikizamini.
3. Nyuma yo gupima gukomera, mugihe utangiye gupima ubukana, ingingo yambere yikizamini ntabwo ikoreshwa. Kubera gutinya umubano mubi hagati yicyitegererezo nubumoya, agaciro kapimwe ntikubaho. Nyuma yingingo ya mbere irageragezwa kandi testers ikomeye iri mubikorwa bisanzwe imikorere, icyitegererezo cyageragejwe kumugaragaro kandi agaciro gakomeye karanditswe.
4. Niba igice cyibizamini cyemerera, muri rusange hitamo ibice bitandukanye kugirango ugerageze byibuze indangagaciro eshatu zikomeye, fata agaciro kagereranijwe, hanyuma ufate agaciro kagereranijwe nkigiciro gikomeye cyibizamini.
5. Kubice bigerageza hamwe nuburyo bugoye, amakaranga yimiterere ijyanye igomba gukoreshwa, kandi irashobora kugeragezwa nyuma yo gukosorwa. Ikizamini cyikizamini gishyirwa mubukonje bwa V kugirango ugerageze.
6. Mbere yo gupakira, reba niba ikiganza cyo gupakira gishyizwe mumwanya upakurura. Iyo gupakira, igikorwa kigomba kuba umucyo kandi gihamye, kandi ntukoreshe imbaraga nyinshi. Nyuma yo gupakira, ikiganza cyo gupakira kigomba gushyirwa mumwanya wo gupakurura, kugirango wirinde igikoresho cyo kuba munsi yigihe kirekire, bigatera imico miremire kandi bigira ingaruka ku gipimo.
Vickers, Rockwell
Gukomera: Nubushobozi bwibikoresho byo kurwanya imiterere ya plastike yaho, kandi birashoboka cyane kopisha uburyo bwo kwerekana indentation.
Icyitonderwa: Indangagaciro zirakomeye ntizishobora kugereranwa nundi, kandi zirashobora guhinduka gusa kubi meza yo kugereranya.
Muri 2019, Shandong Shancai Ikizamini Con, yinjiye muri komite ishinzwe ibizamini by'igihugu ishinzwe ibipimo ngenderwaho kandi yitabira gushyiraho ibipimo bibiri by'igihugu
1. GB / T 230.2-2022: "Ibikoresho by'icyuma bya Rockwell Hardness Ikizamini Igice cya 2: Kugenzura no Guhuza no Gukingura Abafatanyabikorwa Gukomera no kugenerwa"
2. GB / T 231.2-2022: "Ibikoresho bya Britallic Brinell Hardness Ikizamini Igice cya 2: Kugenzura no Guhuza hamwe na Testers Hardst"
Muri 2021, Shandong Shancai yagize uruhare mu iyubakwa ry'umushinga upima umurongo wikora wo kwipimisha kuri Aerosepace imiyoboro ya moteri ya moteri, agira uruhare mu nganda za Aerospace mu kibaya.
