Uburyo bwo Kwipimisha Uburyo bwo Gukora Inkweto za feri zikoreshwa mukuzunguruka (Guhitamo inkweto za feri zo kugerageza gukomera)

Guhitamo ibikoresho byo gupima imashini zikoresha feri yicyuma bigomba kubahiriza ibipimo: ICS 45.060.20. Ibipimo ngenderwaho byerekana ko igeragezwa ryimitungo igabanijwemo ibice bibiri:

1.Ikizamini gikomeye

Bizakorwa hubahirijwe ibivugwa muri ISO 6892-1: 2019. Ibipimo no gutunganya ubuziranenge bwikigereranyo bigomba kuba byujuje ibisabwa ISO 185: 2005.

2.Uburyo bwo Kwipimisha

Bizashyirwa mu bikorwa hakurikijwe ISO 6506-1: 2014. Ingero zigomba gukatirwa kuva igice cyo hepfo yikizamini cyihariye; niba nta kabari k'ibizamini, hafatwa inkweto imwe ya feri, 6mm - 10mm igomba gutegurwa kuruhande rwayo, kandi ubukana bupimirwa ku manota 4 y'ibizamini, hamwe n'impuzandengo y'ibisubizo.

Shingiro ryuburyo bwo gupima ubukana

Ibipimo bisanzwe ISO 6506-1: 2014 “Ibikoresho Byuma - Ikizamini cya Brinell - Igice cya 1: Uburyo bwikizamini” bugaragaza ihame, ibimenyetso nibisobanuro, ibikoresho byikizamini, ingero, uburyo bwo gukora ibizamini, kutamenya neza ibisubizo na raporo yikizamini cya Brinell ikizamini cyibikoresho byuma.

2.1 Guhitamo ibikoresho byikizamini: Ikizamini cya Brinell Ikizamini (Basabwe mbere)

Ibyiza: Agace kerekana indente ni nini, gashobora kwerekana ubukana rusange bwibikoresho bikozwe mucyuma (icyuma gishobora kuba gifite imiterere itaringaniye), kandi ibisubizo birahagarariwe.

Irakwiranye nicyuma giciriritse kandi gikeya (HB 80 - 450), ikubiyemo neza uburemere bwinkweto za feri yicyuma.

Igikorwa kiroroshye cyane, kandi ibisabwa kurangiza hejuru yikigereranyo ni bike (muri rusange Ra 1.6 - 6.3μm birahagije).

2.2 Ihame ryikizamini cya Brinell

Ihame rishobora kuvunagurwa muburyo bukurikira: Umupira ukomeye (cyangwa umupira wazimye) ufite diameter ya 10mm ukanda hejuru yikigereranyo munsi yimbaraga runaka (nka 3000kgf). Nyuma yo gupima diameter ya indentation, agaciro gakomeye (HBW) karabazwe kugirango karanga ubushobozi bwibikoresho byo kurwanya ihindagurika rya plastike. Inyungu yibanze yibanze muburyo bukomeye bwo kwerekana ibisubizo, bishobora kwerekana imiterere ya macroscopique iranga ibintu. Nuburyo bwa kera bukoreshwa cyane mugupima imikorere yibikoresho byuma.

2.3 Ibimenyetso nibisobanuro bya Brinell Gukomera Agaciro

Igisobanuro cyibanze cyagaciro ka Brinell (HBW) ni: ikigereranyo cyingufu zipimisha (F) nubuso bwa indentation (A), hamwe nigice cya MPa (ariko mubisanzwe igice ntikirangwa, kandi hagakoreshwa gusa umubare wumubare). Inzira yo kubara niyi ikurikira: HBW = πD (D - D2 - d2) 2 × 0.102 × F
Aho:

F nimbaraga zo kugerageza (igice: N);

D ni diameter ya indenter (unit: mm);

d ni impuzandengo ya diameter ya indentation (unit: mm);

Coefficient “0.102 ″ ni ikintu cyo guhindura ibintu bikoreshwa muguhindura imbaraga zipimisha kuva kgf ukagera kuri N (iyo ubaze neza muri N, formula irashobora koroshya).

Birashobora kugaragara kuri formulaire ko munsi yimbaraga imwe yikigereranyo hamwe na diameter ya indenter, uko diameter ya indentation iba ntoya, nubushobozi bwibikoresho bwo kurwanya ihindagurika rya plastike, kandi n’agaciro gakomeye ka Brinell; muburyo bunyuranye, hepfo agaciro gakomeye.

Ukurikije ibintu bifatika biranga inkweto za feri zicyuma (ibara ryicyuma), ibipimo byikizamini cya Brinell mubisanzwe ni ibi bikurikira:

Imbaraga zipimisha (F): Mubisanzwe, 3000kgf (29.42kN) irakoreshwa, kandi ikimenyetso gikomereye ni "HBW 10/3000 ″.

Icyitonderwa: Niba icyitegererezo ari gito cyangwa ibikoresho byoroshye, imbaraga zipimisha zirashobora guhinduka (nka 1500kgf cyangwa 500kgf) ukurikije ISO 6506-1: 2014, ariko ibi bizerekanwa muri raporo yikizamini.
