Intangiriro ku byuma bifunga-2

4. Ishusho y'ibice bya Bolt

5. Kumenya Umupira w'Amapine

6. Amanota, Amanota y'Imikorere, n'ibindi.

1. Ibimenyetso: Ku mabati n'amasurufu bifite umurambararo wa hexagonal (umurambararo w'umugozi >5mm), ibimenyetso bigomba gukorwa hejuru y'umutwe hakoreshejwe inyuguti zizamuwe cyangwa zifunze, cyangwa ku ruhande rw'umutwe hakoreshejwe inyuguti zifunze. Ibi birimo amanota y'imikorere n'ibimenyetso by'uwabikoze. Ku byuma bya karuboni: Kode y'ibimenyetso by'imbaraga igizwe n'imibare ibiri itandukanyijwe na "·". Igisobanuro cy'igice cy'umubare kiri imbere ya "·" muri kode y'ibimenyetso kigaragaza imbaraga zo gukurura. Urugero, "4" mu cyiciro cya 4.8 igaragaza imbaraga zo gukurura za 400N/mm2, cyangwa 1/100 by'ibyo. Igisobanuro cy'igice cy'umubare nyuma ya "·" muri kode yo kumenyekanisha kigaragaza igipimo cy'ingufu zo gukurura, ari cyo gipimo cy'ingingo y'ingufu cyangwa imbaraga zo gukurura za nomine ku mbaraga zo gukurura za nomine. Urugero, ingingo y'ingufu z'ibicuruzwa bya 4.8 ni 320N/mm2. Ibimenyetso by'imbaraga z'ibicuruzwa bya icyuma kitagira umugese bigizwe n'ibice bibiri bitandukanyijwe na "-". Ikimenyetso kiri imbere ya "-" muri kode yo kumenyekanisha kigaragaza ibikoresho, nka A2, A4, nibindi. Ikimenyetso kiri inyuma ya "-" kigaragaza imbaraga, nka A2-70.

2). Ingano: Ku byuma bya karuboni, amanota y'imikorere ya mekanike ya metric bolt ashobora kugabanywamo amanota 10 y'imikorere: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, na 12.9. Inkingi itagira umwanda igabanyijwemo ibyiciro bitatu: 60, 70, 80 (austenitic); 50, 70, 80, 110 (martensitic); 45, 60 (ferritic).

7. Gutunganya ubuso

Gutunganya ubuso ahanini bigamije kongera ubushobozi bwo kurwanya ingese, kandi bamwe banatekereza ku ibara, bityo ahanini ni ibintu bikoreshwa mu byuma bya karuboni, muri rusange bisaba gutunganya ubuso. Uburyo busanzwe bwo gutunganya ubuso burimo kwirabura, gushushanya ibyuma, gushushanya umuringa, gushushanya nikeli, gushushanya chrome, gushushanya ifeza, gushushanya zahabu, gushushanya dacromet, gushushanya ibyuma bishyushye, nibindi; hari ubwoko bwinshi bwo gushushanya ibyuma, nka zinki y'ubururu n'umweru, zinki y'ubururu, zinki y'umweru, zinki y'umuhondo, zinki y'umukara, zinki y'icyatsi, nibindi, kandi bishyirwa mu byiciro bitandukanye bitagira ingaruka ku bidukikije n'ibidafitanye isano n'ibidukikije. Buri cyiciro gifite ubunini bwinshi bwo gutwikira kugira ngo gihuze n'ibisabwa bitandukanye byo gupima umunyu.

Incamake y'ibicuruzwa by'ibice bisanzwe by'imodoka

1). Incamake y'ibice bisanzwe by'imodoka

Ibice bisanzwe by'imodoka bifite ubwoko butandukanye kandi bikoreshwa mu gukora ibice bitandukanye n'ibice by'imodoka, ndetse no guhuza no guteranya ibice bitandukanye kugira ngo bikore imodoka yose. Ubwiza bw'ibice bisanzwe bigira ingaruka zikomeye ku bwiza rusange n'imikorere y'ibikoresho bya mekanike, kandi abakora imodoka akenshi bagira uburyo buhamye bwo gusuzuma no kwemeza ibipimo ngenderwaho by'uburyo bwo gutanga ibikoresho. Isoko rinini ry'inganda z'imodoka ritanga umwanya munini wo guteza imbere ibikoresho bisanzwe by'imodoka. Dukurikije imibare, imodoka yoroheje cyangwa itwara abagenzi ikenera ibiro bigera kuri 50 (ibice bigera kuri 5.000) by'ibice bisanzwe, mu gihe imodoka iciriritse cyangwa iremereye ikenera ibiro bigera kuri 90 (ibice bigera kuri 5.710).

2). Imibare y'ibice by'imodoka bisanzwe

Buri ruganda rukora moteri nini mu nganda z’imodoka rukoresha "Amategeko Asanzwe agenga Imibare y’Ibice by’Imodoka" (QC/T 326-2013) kugira ngo rushyireho amabwiriza agenga imibare y’ibice by’ikigo, kandi ibikubiye muri ayo makuru biguma ari bimwe nubwo hari impinduka.

Imibare y'ibice bisanzwe by'imodoka muri rusange igizwe n'ibice 7, bikurikirana:

- Igice cya 1: Kode y'ibice bisanzwe by'imodoka;
- Igice cya 2: Kode y'ubwoko butandukanye;
- Igice cya 3: Guhindura kode (ni ngombwa);
- Igice cya 4: Kode y'ibipimo by'ingano;
- Igice cya 5: Imikorere ya mekanike cyangwa kode y'ibikoresho;
- Igice cya 6: Kode yo gutunganya ubuso;
- Igice cya 7: Kode yo gushyira mu byiciro (ni ngombwa).

Urugero: Q150B1250TF61 yerekana umutwe w'umugozi ufite uburebure bwa M12, uburebure bwa 50mm, urwego rw'imikorere rwa 10.9, n'igitambaro cya zinc kidakoresha amashanyarazi (ifeza-imvi). Uburyo bwo kwerekana ni ubu bukurikira:
