I-Hexagon Flange Bolts ene-Dacromet Coating: Ijometri, iNkqubo, iNtsebenzo kunye neSikhokelo seNdibano
2026-10-26
1. Intshayelelo
I-Flange bolts - i-hexagon head bolts ene-flange edibeneyo (ubuso be-washer) eyakhelwe entloko - ibe yinto ekhethiweyo yokuzikhethela kwimveliso yeemoto, ukudibanisa koomatshini, kunye nokwakhiwa kwemibhobho. Ngokudibanisa ibholiti kunye newasha ibe yindawo enye, ibholithi yeflange yenza lula ukuhlangana, isasaze umthwalo obambezelayo kwindawo enkulu yokuthwala, kwaye iphucula ukuxhathisa ukuzikhulula phantsi kokungcangcazela.
Kwiindawo zenkonzo ezinobungozi, nangona kunjalo, izibonelelo zoyilo lweflange zinokuqondwa kuphela ukuba i-coating ekhusela i-bolt ihlala ixesha elide njengoko idibeneyo ngokwayo. I-Dacromet (i-zinc-aluminiyam i-flake) i-flake ivele njengeyona ndlela ikhethiweyo yokukhusela i-corrosion-protection ye-bolts ephezulu yamandla e-flange, enikezela ukuxhathisa ityuwa yokutshiza amaxesha amaninzi ngaphezu kwe-electro-galvanizing kwiqhezu lobunzima be-hot-dip galvanizing - kwaye ngaphandle komngcipheko we-hydrogen embrittlement.
Eli nqaku lichaza ijometri kunye nemigangatho ye-hex flange bolts, ichaza inkqubo yokugqoka i-Dacromet njengoko isetyenziswe kwiibholithi ze-flange, inikezela uthelekiso lwentsebenzo kunye neenkcukacha eziqhelekileyo, kwaye inika ukhetho olusebenzayo kunye nesikhokelo sokuhlanganisa.
2. Yintoni i-Hex Flange Bolt?
I-hex flange bolt yi-hexagon head bolt entloko iphethe i-flange ejikelezayo edibeneyo kumphezulu wokuthwala, ngokwe-ISO 4162 / DIN 6921 (metric) kunye nemigangatho ethelekisekayo ye-intshi-series. Iintsapho ezimbini zoyilo zikhona:
- Uluhlu oluncinci lweflange- i-compact flange diameter yeendawo ezixineneyo, eziqhelekileyo kwiinjini zeemoto;
- Uchungechunge olukhulu (olubanzi) lweflange- malunga ne-1.5 × intambo ye-diameter ethwele umphezulu, esetyenziswa apho imithwalo ephezulu yokuthwala okanye izinto zokubethelela ezithambileyo (i-aluminiyam, iiplastiki) zibandakanyeka.
Iibholiti ezininzi zeflange nazo zibandakanya iiserations (amazinyo eradial) kwiflange ngaphantsi. I-serrations iluma kwindawo yokukhwelana, inyusa ukuxhathisa kwintshukumo encinci kunye nokuphucula ukuxhathisa kwebholiti ukuzikhulula phantsi kokungcangcazela okunqamlezayo - ngaphandle kokufuna iwasha yesitshixo esahlukileyo.
3. Kutheni i-Dacromet Coating ye-Flange Bolts?
I-Dacromet yokugqoka i-slurry esekelwe emanzini ye-zinc kunye ne-aluminium flakes ene-passivators kunye ne-inorganic binders. Amalungu afakwe kwi-dip-coated, centrifugally spun ukususa i-slurry engaphezulu, kwaye anyangelwe kwi-280-330 ° C imizuzu engama-20-40; Imijikelo emibini yediphu-spin idla ngokuvelisa ifilimu eyi-6–10 μm. Iibholiti zeflange zifaneleke ngokukodwa kwinkqubo ye-dip-spin:
1.Inkcazo epheleleyo- i-coating igeleza kwi-flange-to-shank fillet kunye ne-serration grooves, iindawo apho i-electroplating ihlala ishiya iidiphozithi ezincinci okanye ezingaqhelekanga;
2.Ubukhulu obufanayo- i-centrifugal spinning inika iifilimu ngaphaya kobuso obuthe tyaba, igcina umphezulu onxuseneyo wokuthwala obaluleke kakhulu ekuchanekeni komthwalo wokubamba;
3.Akukho embrittlement hydrogen- akukho pickling ye-asidi okanye i-electrolytic current echaphazelekayo, ngoko ke amabakala 10.9 kunye ne-12.9 anokuthi afakwe ngokukhuselekileyo;
4.Ukuchaneka komsonto- ifilimu enqabileyo, enzima igcina i-geometry yentambo, ngoko ke iibholiti ze-flange zisaqhuba ngokukhululekileyo kwimingxuma echothiweyo kunye neqabane kunye namantongomane e-flange;
5.Ukungaguquguquki kwefriction- kunye ne-lubricant topcoats edibeneyo, i-Dacromet flange bolts ifezekisa izinto ezizinzileyo ze-nut (K ≈ 0.12-0.16), ziyimfuneko kwimigca yendibano elawulwa yi-torque.
4. Ukusebenza kunye neeNzuzo zoomatshini
Indawo yokuthwala kunye noxinzelelo lwangaphezulu
Inzuzo echazayo yoyilo lweflange kukuhanjiswa komthwalo. Itheyibhile engezantsi ithelekisa i-M10 ye-hex bolt eqhelekileyo, i-hex bolt enewasha eyahlukileyo, kunye ne-M10 enkulu-flange bolt kumthwalo ofanayo we-30 kN.
| Ubumbeko lwebholt | Ukuthwala i-OD (malunga.) | Indawo yokuthwala (mm²) | Uxinzelelo lomphezulu kuma-30 kN (N/mm²) |
| Hex bolt DIN 933, akukho washer | 14.5 mm (ubuso bokuhlamba) | ≈ 78 | ≈ 385 |
| Ibholithi yeHex + iwasha ecaba DIN 125 | 20 mm | ≈ 166 | ≈ 181 |
| Hex flange bolt DIN 6921 | 21.5 mm | ≈ 208 | ≈ 144 |
Itheyibhile 1. Indawo yokuthwala kunye nokuthelekiswa koxinzelelo lomphezulu (umzekelo we-M10, amaxabiso aqhelekileyo).
Umzobo 2. Uxinzelelo lomphezulu osezantsi luthetha ukushumeka okuncinci kwindawo ethambileyo okanye epeyintiweyo kunye nejoyinti eqinile ngokuhamba kwexesha.
Uxinzelelo lomphezulu osezantsi lunciphisa ukubethelwa (i-brinelling) kwi-aluminiyam okanye indawo epeyintiweyo, igcina ilungu elibambelweyo liqina ngokuhamba kwexesha, kwaye yehlisa umngcipheko wokutshona kwentloko kwizinto ezithambileyo. Ukongeza, uvavanyo oluzimeleyo lwe-transverse-vibration (uvavanyo lwe-Junker, i-DIN 65151) lubonisa rhoqo ukuba iibholiti ze-flange ezixubileyo zigcina umthwalo omkhulu we-clamp kune-hex bolts ezicacileyo zebakala elifanayo, kuba iiserrations zitshixa i-bearing interface kunye ne-flange ebanzi imelana nokujikeleza kwentloko.
