Hexagon Flange Bolts hamwe na Dacromet Coating: Geometrie, Inzira, Imikorere nubuyobozi bwinteko
2026-10-26
1. Intangiriro
Ibikoresho bya flange - hexagon umutwe wumutwe hamwe na flange ihuriweho (isabune yogejwe) yubatswe mumutwe - byahindutse byihuse mugukora amamodoka, guteranya imashini, no kubaka imiyoboro. Muguhuza Bolt hamwe nogeshe mugice kimwe, flange bolt yoroshya guterana, ikwirakwiza umutwaro wo gufatira hejuru yikibanza kinini, kandi igateza imbere kurwanya kwigobotora munsi yinyeganyeza.
Mubidukikije byangiza ibidukikije, icyakora, inyungu zubushakashatsi bwa flange zishobora kugerwaho gusa mugihe igifuniko kirinda bolt kibaho igihe cyose hamwe. Ipitingi ya Dacromet (zinc-aluminium flake) yagaragaye nka sisitemu yatoranijwe yo gukingira ruswa kugirango ibe ifite imbaraga nyinshi zo mu bwoko bwa flange, itanga imbaraga zo kurwanya umunyu inshuro nyinshi kuruta amashanyarazi ya elegitoronike ku gice gito cy’ubunini bwa hot-dip galvanizing - kandi nta ngaruka mbi ya hydrogène.
Iyi ngingo isobanura geometrike nuburinganire bwa hex flange bolts, isobanura inzira yo gutwikira Dacromet nkuko ikoreshwa kuri flangine, ikagereranya imikorere nibikorwa bisanzwe, ikanatanga amahitamo meza hamwe nubuyobozi bwo guterana.
2. Hex Flange Bolt ni iki?
Hex flange bolt ni umutwe wa hexagon umutwe wumutwe we utwara uruziga ruzengurutse uruziga hejuru, kuri ISO 4162 / DIN 6921 (metric) hamwe nibipimo bigereranywa na santimetero. Imiryango ibiri yashushanyije irahari:
- Urutonde ruto- diametre yoroheje ya diameter kumwanya muto, usanzwe muri moteri yimodoka;
- Urukurikirane runini (rugari)- hafi ya 1.5 × yumurambararo wa diametre ifite ubuso, ikoreshwa aho imitwaro iremereye cyangwa ibikoresho byoroshye byo gufunga (aluminium, plastike).
Ibice byinshi bya flange byongeye biranga seriveri (amenyo ya radiyo) kuri flange munsi. Seriveri iruma hejuru yubukwe, byongera imbaraga zo kugendana na mikoro igereranije no kunoza uburyo bwa bolt bwo kwigobotora munsi yinyeganyeza ihindagurika - udakeneye gukaraba neza.
3. Kuki Dacromet Coating ya Flange Bolts?
Ipitingi ya Dacromet ni amazi ashingiye kumazi ya zinc na aluminiyumu hamwe na passivator hamwe na binders. Ibice bifatanyirijwe hamwe, bizunguruka hagati kugirango bikureho ibishishwa birenze, kandi bikize kuri 280–330 ° C muminota 20-40; inzinguzingo ebyiri zisanzwe zitanga firime ya 6-10. Ibibabi bya flange bikwiranye cyane na dip-spin:
1.Gukwirakwiza byuzuye- igipfundikizo gitemba muri flange-to-shank fillet hamwe na seriveri ya seriveri, ahantu amashanyarazi akunda gusiga ibintu byoroshye cyangwa bidasanzwe;
Ubunini bumwe- kuzunguruka hagati ya centrifugal itanga na firime hejuru yisura ya flange, ikabika ubuso buringaniye bufite akamaro kanini kuri clamp-load;
3.Nta hydrogène- nta gutoranya aside cyangwa amashanyarazi ya electrolytike arimo, bityo icyiciro cya 10.9 na 12.9 gishobora gutwikirwa neza;
4.Soma neza- firime yoroheje, ikomeye irinda urudodo rwa geometrie, bityo flange bolts iracyiruka mubwisanzure mu mwobo wafashwe kandi ugahuza nimbuto zisanzwe za flange;
5. Guhuzagurika- hamwe na kote ya lubricant topcoats, Dacromet flange bolts igera kubintu byiza bihamye (K ≈ 0.12–0.16), nibyingenzi kumurongo uteganijwe kugenzurwa na torque.
4. Imikorere ninyungu za mashini
Agace kegeranye hamwe nigitutu cyo hejuru
Igisobanuro cyiza cya flange igishushanyo ni kugabura imitwaro. Imbonerahamwe ikurikira iragereranya M10 hex isanzwe, hex bolt hamwe nogeshe itandukanye, hamwe na M10 nini-flange bolt kuri 30 kN yuzuye umutwaro.
| Ibikoresho bya Bolt | Gutwara OD (hafi.) | Agace kegeranye (mm²) | Umuvuduko wubuso kuri 30 kN (N / mm²) |
| Hex bolt DIN 933, nta washer | Mm 14,5 (wogeje) | ≈ 78 | ≈ 385 |
| Hex bolt + isabune isukuye DIN 125 | Mm 20 | 6 166 | ≈ 181 |
| Hex flange bolt DIN 6921 | 21,5 mm | ≈ 208 | ≈ 144 |
Imbonerahamwe 1. Kwerekana ahantu hamwe no kugereranya umuvuduko wo hejuru (M10 urugero, indangagaciro zisanzwe).
Igicapo ca 2. Umuvuduko wo hasi bisobanura kwinjiza bike mubice byoroshye cyangwa bisize irangi hamwe ningingo ikomeye mugihe runaka.
Umuvuduko wo hasi ugabanya gushira (brinelling) muri aluminiyumu cyangwa hejuru yisize irangi, bigatuma ingingo ifatanye ifatanye mugihe, kandi bikagabanya ibyago byo mumutwe kurohama mubikoresho byoroshye. Byongeye kandi, kwigenga kwihinduranya-kwinyeganyeza (Ikizamini cya Junker, DIN 65151) byerekana buri gihe ko flange ya seriveri ikomeza kugumana umutwaro uremereye ugereranije na hex ya bolx yo mu cyiciro kimwe, kubera ko seriveri ifunga interineti kandi flange nini ikarwanya kuzunguruka umutwe.
