Ibyuma bitagira umuyonga: Hex Bolts hamwe n amanota yibikoresho
2026-08-05
1. Intangiriro
Ibyuma bitagira umwanda bihuza kurwanya ruswa hamwe nimbaraga za mashini, bigatuma biba ngombwa mubwubatsi, inyanja, gutunganya ibiryo, ninganda zubuvuzi. Bitandukanye nicyuma cya karubone gisaba gutwikirwa, ibyuma bidafite ingese biva mukurwanya kwangirika kwa chromium oxyde. Aka gatabo karimo ibintu bibiri byingenzi: igishushanyo cya hex bolt hamwe nicyiciro cyo gutoranya ibyuma.
2. Hex Bolts
Hex bolts iranga umutwe wimpande esheshatu zituma ihererekanyabubasha ryimikorere ikoresheje imirongo isanzwe cyangwa socket. Igishushanyo kigizwe n'umutwe wa mpande esheshatu, shanki idasomwe, igice cyometseho, hamwe n'inama. Ibyiza byingenzi birimo ubushobozi bwumuriro mwinshi, kugerwaho kwisi yose, gukora neza, kongera gukoresha, no kubahiriza amahame mpuzamahanga (ISO 4014, DIN 933, ASTM A325).
Imbonerahamwe 1. Ingano ya Hex Bolt Ingano (Icyuma kitagira umuyonga)
| Ingano y'izina | Ikibanza cy'insanganyamatsiko (TPI) | Ubugari bw'umutwe (mm) | Imbaraga za Tensile (MPa) |
| 1/4 - 20 | 20 | 11.1 | 520 |
| 3/8 - 16 | 16 | 14.3 | 520 |
| 1/2 - 13 | 13 | 19.1 | 520 |
| 3/4 - 10 | 10 | 28.6 | 520 |
3. Ibyiciro byicyuma
Ibyuma bidafite ibyuma byashyizwe mumiryango ine: austenitis (304, 316 - itari magnetique, irwanya ruswa), ferritic (430 - magnetique, ubukungu), martensitike (410 - gukomera, kwangirika kugereranije), no gukomera kw'imvura (17-4PH - imbaraga nyinshi). Munsi ya ISO 3506, amanota akoresha inyuguti-nimero kode aho A = austenitike, C = martensitike, kandi umubare ugaragaza imbaraga zingirakamaro (50/70/80).
Imbonerahamwe 2. Ibyiciro Byuma Byuma Byuma bya Bolts
| Icyiciro | Icyiciro cya ISO | Tensile (MPa) | Kurwanya ruswa. | Ibyingenzi | Porogaramu isanzwe |
| 304 | A2-70 | 700 | Nibyiza | 18% Cr, 8% Ni | Intego rusange, ibiryo |
| 316 | A4-70 | 700 | Cyiza | 16% Cr, 10% Ni, 2% Mo. | Inyanja, imiti, ubuvuzi |
| 410 | C3-80 | 550 | Guciriritse | 12% | Ibikoresho, indangagaciro |
| 17-4PH | A4-80 | 800 | Nibyiza | 16% Cr, 4% Ni, 4% Cu | Ikirere, imbaraga-nyinshi |
3.1 Guhitamo amanota kubidukikije
Imbonerahamwe 3. Ibyiciro byasabwe nibidukikije bya serivisi
| Ibidukikije | Icyiciro Cyifuzo | Impamvu |
| Mu nzu / Kuma | 304 (A2) | Birahagije ku giciro gito |
| Hanze / Inkombe | 316 (A4) | Mo irwanya igitero cya chloride |
| Uruganda rukora imiti | 316L / 904L | Kurwanya aside iruta iyindi |
| Imbaraga Zikenewe | 17-4PH (A4-80) | Imvura irakomera |
4. Ibitekerezo by'ingenzi
Galling: Ibyiciro bya Austenitike (304, 316) bikunda gufata urudodo mugihe cyo gukomera. Koresha anti-seize ibice cyangwa ibisa nudusanduku (A2 bolt hamwe na A4 nut) kugirango ugabanye.
Passivation: Kuvura aside (ASTM A967) ikuraho icyuma cyubusa kandi ikongera urwego rwa oxyde, igatera imbaraga zo kurwanya ruswa nyuma yo gukora.
Magnetism: Indangamanota ya Austenitike ntabwo ari magnetique iyo ihujwe ariko irashobora guhinduka igice cya magnetiki nyuma yo gukora ubukonje. Ibyiciro bya Ferritic na martensitike ni magnetique.
5. Umwanzuro
Ibyuma bitagira umuyonga bihuza igishushanyo mbonera cya geometrike hamwe na metallurgical vertabilite. Kuva mubyiciro byubukungu Icyiciro cya 304 kugirango ukoreshwe muri rusange kugeza imbaraga-17-4PH zisaba ibisabwa, guhuza amanota meza na serivisi ya serivisi bitanga imikorere myiza no kuramba.
