Hexagon Flange Bolts oo leh Dacromet: Joometri, Habka, Waxqabadka iyo Hagida Golaha
2026-10-26
1. Hordhac
Dhalooyinka Flange - boolal madax hexagon ah oo leh flange isku dhafan (wejiga dhaqida) oo lagu dhex dhisay madaxa - waxay noqdeen xiraha doorashada ee wax soo saarka baabuurta, isku imaatinka mishiinka, iyo dhismaha dhuumaha. Marka la isku daro bolt-ka iyo maydhista hal qayb, bolt flange-ku waxa uu fududeeyaa isu-ururinta, waxa uu u qaybiyaa culayska isku xidhka meel weyn oo xajin ah, waxana uu wanaajiyaa iska caabinta is-dejinta gariirka hoostiisa.
Si kastaba ha ahaatee, jawiga adeega daxalka ah, si kastaba ha ahaatee, faa'iidooyinka naqshadeynta flange waxaa la xaqiijin karaa oo kaliya haddii daaha ka ilaaliya boolka uu noolaado ilaa inta wadajirka laftiisa. Dacromet (zinc-aluminium flake) daahan ayaa u soo baxay sida nidaamka ilaalinta daxalka-doorbidayaa loogu talagalay bolts flange xoog-sare, bixinta caabbinta milix dhowr jeer ka weyn electro-galvanizing oo qayb ka mid ah dhumucdiisuna of kulul-muquufin galvanizing - iyo iyada oo aan wax khatar ah hydrogen embrittlement.
Maqaalkani wuxuu sharxayaa joomatari iyo halbeegyada xargaha hex flange, wuxuu qeexayaa habka daahan Dacromet sida lagu dabaqay boolal flange, wuxuu soo bandhigayaa isbarbardhigga waxqabadka iyo qeexitaannada caadiga ah, wuxuuna bixiyaa xulasho wax ku ool ah iyo hagitaan ururinta.
2. Waa maxay Hex Flange Bolt?
Daboolka hex flange waa bool madax hexagon ah oo madaxiisu uu sido flange wareeg ah oo isku xiran oo ku yaal dusha sare ee xajinta, marka loo eego ISO 4162 / DIN 6921 (metric) iyo heerarka taxanaha inch ee isbarbardhigga ah. Laba qoys ayaa nashqadeeyay:
- Taxane flange yar- dhexroorka flange is haysta ee meelaha cidhiidhiga ah, oo ku badan matoorada baabuurta;
- Taxane flange weyn (ballaaran).- Qiyaastii 1.5 × dun dhexroorka dusha sare leh, oo loo isticmaalo halka culeyska sareeyo ama walxaha isku dhejinta jilicsan (aluminium, balaastikada) ay ku lug leeyihiin.
Boolal badan oo flange ah ayaa sidoo kale leh seerayaal (ilko shucaac ah) oo ku yaal garabka hoose. Seerations-yadu waxay qaniinaan dusha sare ee lammaane, iyaga oo kordhinaya caabbinta dhaqdhaqaaqa-yar ee qaraabo ah iyo hagaajinta caabbinta boodhka ee is-dabcinta gariir-rogrogmi - iyada oo aan loo baahnayn quful gooni ah.
3. Waa maxay sababta Dacromet-ka loo daboolayo Flange Bolts?
Dahaarka Dacromet waa qulqulka biyaha ku salaysan ee zinc iyo aluminium flakes oo leh passivators iyo xidhayaasha aan organic ahayn. Qaybaha waa la dahaadhay, si sentrifugal ahaan miiqan si meesha looga saaro dheecaanka xad-dhaafka ah, oo lagu daaweeyaa 280-330 ° C 20-40 daqiiqo; Laba wareeg oo wareeg ah ayaa sida caadiga ah keena filim 6-10 μm ah. Dhalooyinka caleenku waxay si gaar ah ugu habboon yihiin habka-dib-spin-ka:
1.Dhammaan daboolka- dahaarka qulqulaya galay fillet flange-to-shank iyo grooves serration, meelaha electroplating inta badan ka tago kayd khafiif ah ama aan joogto ahayn;
2. Dhumucdiisuna tahay lebbiska- Wareegga centrifugal wuxuu bixiyaa xitaa filimada wejiga flange-ga siman, isagoo ilaalinaya dusha sare ee isbar-bar socda ee muhiimka u ah saxnaanta xajinta;
3.Hadrojiin-ku-marin- Ma jiro aashito-qaadis ama koronto-dhal ah oo ku lug leh, markaa fasalada 10.9 iyo 12.9 si badbaado leh ayaa loo dabooli karaa;
4.Trin sax ah- filimka khafiifka ah, ee adag wuxuu ilaaliyaa joomatari dunta, sidaas darteed boolalyada flange waxay wali si xor ah u galaan godad la taabtay oo saaxiib la wadaaga lowska flange caadiga ah;
5. Joogtaynta khilaafka- oo leh koofiyadaha dufan ee isku dhafan, Dacromet flange bolts waxay gaadhaan qodobbada lowska ee deggan (K ≈ 0.12-0.16), oo lagama maarmaan u ah khadadka shirarka ee la xakameeyo.
4. Waxqabadka iyo Faa'iidooyinka Farsamada
Meesha xajinta iyo cadaadiska dusha sare
Faa'iidada qeexan ee naqshadeynta flange waa qaybinta culeyska. Jadwalka hoose wuxuu isbarbar dhigayaa halbeegga M10 hex bolt, hex bolt oo leh weel gaar ah, iyo bool weyn oo M10 ah oo isku mid ah 30kN.
| Qaabeynta Bolt | Qaadashada OD (qiyaastii.) | Meesha wax lagu qaado (mm²) | Cadaadiska dusha sare ee 30 kN (N/mm²) |
| Hex bolt DIN 933, ma jiro dhaqe | 14.5 mm (wajiga dhaqda) | ≈ 78 | ≈ 385 |
| Hex bolt + weel fidsan DIN 125 | 20 mm | ≈ 166 | ≈ 181 |
| Hex flange bolt DIN 6921 | 21.5 mm | ≈ 208 | ≈ 144 |
Shaxda 1. Isbarbardhigga aagga xajinta iyo cadaadiska dusha sare (tusaale M10, qiyamka caadiga ah).
Jaantuska 2. Cadaadiska dusha hoose waxa uu ka dhigan yahay ku-xidhid yaraanta sagxadaha jilicsan ama rinji iyo kala-goysyada adag muddo ka dib.
Cadaadiska dusha hoose wuxuu yareeyaa ku-xidhka (brinelling) ee aluminiumka ama sagxadaha rinji, waxay ilaalinaysaa wadajirka isku-xidhan ee waqti ka dib, waxayna hoos u dhigtaa khatarta ah in madaxu ku quuso walxo jilicsan. Intaa waxaa dheer, tijaabinta gariir-wareejinta madax-bannaan (Tijaabada Junker, DIN 65151) waxay si joogto ah u muujineysaa in boolal-beelka seereysan ay hayaan culeys aad u badan marka loo eego boolal hex cad oo isku darajo ah, sababtoo ah xargaha ayaa quful interface-ka wax-qabadka iyo flange-ga ballaaran ayaa ka hortagaya wareegga madaxa.
