Icyiciro 10.9 Ubururu-Bwera Zinc Hex Bolt DIN 933 | ISO 4017 | Byuzuye-Umutwe Hexagon Bolt hamwe na Zinc Electroplating & Ubururu-Bwera Passivation

2026-07-10

Icyiciro cya 10.9 Ubururu-Bwera Zinc DIN 933 hex itanga imbaraga-zo gukomera (imbaraga zingana ≥ 1,040 MPa) hamwe nigiciro cyinshi, RoHS yujuje imitako-kandi ikora neza. Nibyihutirwa guhitamo guteranya moteri yimodoka, imashini ziremereye, guhuza umuyaga wa turbine, hamwe nibyuma byubatswe aho bikenewe, guhuza imbaraga-gukomera-imbaraga.

Icyiciro 10.9 DIN 933 Hex Bolt hamwe na Blue-White Zinc Electroplating Kurangiza

Igice cya 1 - Icyiciro cya 10.9: Imbaraga-zohejuru Icyiciro Cyihuta

Icyiciro cya 10.9 nicyiciro cya kabiri murwego rwo hejuru rusanzwe rwumutungo wa metero 898-1, wicaye hagati yicyiciro cya 8.8 gikoreshwa cyane na ultra-high-strength Grade 12.9. Itanga impirimbanyi zingirakamaro zingufu nyinshi, ihindagurika ryemewe, hamwe numunaniro uteganijwe gukora, bigatuma uba umwirondoro wambere kubintu bihindagurika cyane mumashanyarazi, ingufu, hamwe nimashini ziremereye.

Icyiciro cyumutungo

Umubare wambere (10): Yerekana 1/100 cyingufu zumwanya muto muri MPa → imbaraga ntoya = 1.000 MPa (isanzwe kuri 1.040 MPa).
Umubare wa kabiri (9): Yerekana igipimo cyimbaraga ntoya yumusaruro nimbaraga ntoya zingana × 10 → igipimo cyumusaruro = 0,90, bivuze imbaraga nke zumusaruro = 940 MPa.

Ibikoresho bya mashini

Icyiciro cya 10.9 gifatirwa mu byuma bivangwa - mubisanzwe 40Cr, 35CrMo, 42CrMo, cyangwa SCM435 - bivura ubushyuhe nubushyuhe (Q&T) bivura ubushyuhe. Carbone yo hejuru hamwe nibisigazwa (Cr, Mo) itanga ubukana bukenewe kugirango ugere kuri 32-39 HRC yibanze ikenewe mugice cyose, ndetse no mubipimo binini (kugeza M36).

Imfunguzo zingenzi zo gusaba

Imodoka: Moteri yo gushiraho moteri, guhuza inkoni, ibyuma bifata ibyuma, ibyuma bya pivot yo guhagarika, guhuza kuyobora.
Ingufu z'umuyaga: Igice cy'umunara flanges, nacelle yubatswe ihuza, ikibuga gifite ibyuma.
Imashini ziremereye: Gucukumbura inzira ya bolts, buldozer ikadiri ihuza, crane yishe impeta.
Kubaka ibyuma: Imbere-yuzuye-friction-grip ihuza (BS EN 14399-3 HR sisitemu), ibiraro bitwara inteko.

Igice cya 2 - DIN 933: Byuzuye-Urudodo Hexagon Bolt Igipimo

DIN 933 isobanura neza urudodo rwa hexagon-umutwe wa bolts hamwe na metric coarse pitch thread kuva M1.6 kugeza M52. Nubwo tekinike yasimbuwe na ISO 4017, DIN 933 iracyari igipimo gikunze kuvugwa cyane mu nyandiko z’amasoko y’iburayi, ibishushanyo bya tekiniki, hamwe n’ibiciro by’ibikoresho ku isi.

Ibyingenzi Ibipimo

Shank yuzuye-shank: Urudodo rugera ku burebure bwose, kugabanya uburebure bwa clamp uburebure no koroshya ibarura - igice kimwe gisimbuza gufata-uburebure-bwihariye-bwihariye igice cyiziritse.
Hexagon umutwe: Ubugari hejuru ya etage (s) kuri DIN EN ISO 272. Uburebure bwumutwe (k) butanga umwanya uhagije wo guterana gukaraba hamwe no gusezerana.
Ikibanza kiboneye: Kuri ISO 261 / ISO 724. Urudodo ruto rwihanganira kwangirika kwubutaka, ntibikunze guhitanwa, kandi byihuse guterana kuruta ubundi buryo bwiza.
Urwego rwo kwihanganira: Urwego rwibicuruzwa A kubunini ≤ M24 n'uburebure ≤ 10d cyangwa ≤ 150 mm; urwego rwibicuruzwa B kubunini bunini (ISO 4759-1).

DIN 933 Icyiciro cya 10.9

Ibisanzwe bisanzwe DIN 933 ingano yo mu cyiciro cya 10.9 (M6 - M24). Imizigo iremereye ibarwa byibuze byibuze guhangayika × 1,040 MPa.

Ingano	Ikibanza (mm)	s (mm)	k (mm)	Min. Umutwaro uremereye (kN)	Uburebure
M6	1.00	10	4.0	15.8	Mm 10-90
M8	1.25	13	5.3	29.1	Mm 16-150
M10	1.50	17	6.4	46.5	Mm 20-200
M12	1.75	19	7.5	67.3	Mm 20-300 mm
M16	2.00	24	10.0	122	25-300 mm
M20	2.50	30	12.5	191	Mm 30-400 mm

s = ubugari bwizina hejuru yamagorofa, k = uburebure bwumutwe. Umutwaro uremereye kuri ISO 898-1 ahangayitse × 1,040 MPa.

Ikimenyetso

Buri cyiciro cya 10.9 DIN 933 bolt irangwa n'umutwe hamwe na "10.9" n'ikimenyetso kiranga uwabikoze nkuko bisabwa na ISO 898-1. Ubururu-bwera zinc irangiza itanga ako kanya igaragara kandi ifasha muburyo bwo kugenzura ubuziranenge.

Igice cya 3 - Ubururu-Bwera Zinc Amashanyarazi

Zinc yubururu-bwera (Zn / An / Cn / T0 kuri ISO 2081, cyangwa Ubwoko bwa II SC 1 kuri ASTM B633) ni zinc electroplated coating yarangiye hamwe na chromium ntoya (Cr-III) ihinduka ry'ubururu-bwera. Ihuza uburyo bwo kurinda ruswa iringaniye, igaragara neza igaragara neza, hamwe nigiciro gito - bigatuma iba imwe mu miti izwi cyane kubutaka bwimbaraga zikomeye zikoreshwa mubidukikije bikingiwe.

Uburyo Ubururu-Bwera bwa Zinc Bikora

Inzira ikubiyemo intambwe eshatu zikurikiranye:

Gukora amashanyarazi no gukora: Ubuso bwa bolt bwaragabanutse kandi bukora aside kugirango habeho guhuza zinc imwe.
Zinc electrodeposition: Igice cya zinc nziza (8-12 µm) gishyirwa mumashanyarazi kuri substrate yicyuma muri acide cyangwa kwiyuhagira alkaline.
Ubururu-bwera passivation: Bolt yashizwemo vuba yinjijwe mumashanyarazi ya chromium (Cr-III) itambutse, ikora firime yoroheje yoroheje-yubururu ihindura zinc kandi itanga ibimenyetso biranga ubururu-bwera.
Hydrogen de-embrittlement guteka: Icyiciro cya 10.9 gitetse kuri 190-220 ° C mumasaha 4-8 mugihe cyamasaha 4 yo gufata (ISO 9588) kugirango wirukane hydrogène ikwirakwizwa no kwirinda kuvunika gutinda.

Ibisobanuro bya tekiniki

Parameter	Ibisobanuro	Bisanzwe	Ijambo
Ubwoko bwo gutwikira	Zinc electroplate + ubururu-bwera passivation	ISO 2081 / ASTM B633	Trivalent Cr (III)
Umubyimba	8–12 µm (Fe / Zn 8c)	ISO 2081	Kubika urudodo rukwiye
Gusiga umunyu (NSS)	≥ 96 h ingese yera, ≥ 240 h ingese zitukura	ISO 9227	Ubwoko bwa II, SC 1
Kugaragara	Ubururu bumwe-bwiza hamwe na iridescence	ISO 2081	Imitako + ikora
Hydrogen De-embrittlement	Guteka kuri 190-220 ° C kuri 4-8 h muri 4h zisahani	ISO 9588	Ibiteganijwe mu cyiciro cya 10.9
RoHS / KUGERAHO	Yujuje (Cr-VI yubusa trivalent passivation)	2011/65 / EU	Kubungabunga ibidukikije
Coefficient de frais	µ = 0.12–0.20 (nkuko byashyizweho)	ISO 16047	Igenzura ryizewe

Kurwanya umunyu kuri ISO 9227 utabogamye wumunyu (NSS). Ingese yera = ibicuruzwa byangirika; ingese itukura = ibyuma byubatswe byangirika. Hydrogen de-embrittlement ni itegeko kubifata bafite ubukana ≥ 320 HV kuri ISO 4042.

Ibyiza byo mu cyiciro cya 10.9

Ubwishingizi bugaragara: Icyerekezo cyiza, kimwe cyubururu-cyera kirangiza gukora ubuso (gushushanya, ahantu hadatewe, kwanduza) guhita bigaragara mugihe cyo kugenzura.
Guhuza ingingo: Kuri 8-12 µm, igipfundikizo ni gito cyane kugirango ubungabunge kwihanganira urudodo rusanzwe (6g / 6h) utongeye gukanda - ni ingenzi cyane ku ngingo zikomeye.
Kugenzura amakimbirane: Ubuso bushyizweho butanga coeffisiyoneri ihamye (µ ≈ 0.12–0.20), ishyigikira ibara ryizewe rishingiye kubibara mbere yo kubara.
Ikiguzi: Zinc electroplating nuburyo bukoreshwa cyane mukurinda ruswa kubifata, hamwe nigiciro cyo gutunganya cyane ugereranije na Dacromet cyangwa hot-dip galvanizing.
Kubahiriza ibidukikije: Trivalent (Cr-III) passivation yujuje RoHS nibisabwa; bitandukanye na chromium ishaje (Cr-VI), ntabwo byangiza ibidukikije cyangwa kubuzima bwakazi.

Imipaka & Imyitozo myiza

Isahani yubururu bwera-yera igenewe imbere no hanze irinzwe hanze (ibyiciro bya ruswa C1 - C2 kuri ISO 12944). Kugirango ugaragare hanze, ibidukikije byo ku nkombe (C3 +), cyangwa porogaramu zisaba ≥ 480 h kurwanya imiti yumunyu, tekereza Dacromet cyangwa hot-dip galvanizing. Buri gihe ugaragaze hydrogen de-embrittlement guteka kubitumiza byo kugura Icyiciro cya 10.9 zinc-plaque.

Ibyerekeye Ibyuma bya Fujirui - Abakora umwuga wo kwihuta no gukora ibicuruzwa

Fujirui Metal ikora kandi ikohereza ibicuruzwa bifata neza harimo Icyiciro cya 8.8 / 10.9 / 12.9 hex, DIN 933 yuzuye-imigozi yuzuye, DIN 931 igice-cy-igice-cyuma, ibyuma bya sitidiyo, hamwe na feri yihariye. Amahitamo yo kuvura hejuru arimo ubururu-bwera zinc, zinc yumuhondo, Dacromet, Ruspert, gushyushya-gushya, hamwe na plaque ya zinc. Ibicuruzwa byose bikozwe mubipimo bya ISO, DIN, na ASTM hamwe nimpamyabumenyi yuzuye y'ibizamini (MTC) irahari.
