Koofiyadaha Madaxa Socket Socket-Dacromet

2026-11-03

1. Hordhac

Koofiyadaha madaxa ee godka, oo lagu qiyaaso ISO 4762 / DIN 912 - waa boolal-doorasho meel kasta oo rarka xajinta sarreeya, madaxyada is haysta, iyo xakamaynta qulqulka saxda ah ay isugu yimaadaan. Sababtoo ah waxaa sida caadiga ah lagu soo saaray fasalada hantida 8.8, 10.9 iyo gaar ahaan 12.9, bolts-yadani waxay ku shaqeeyaan boqolkiiba sare ee xooggooda wax-soo-saarka, isla xooggaas ayaa ka dhigaya kuwo si gaar ah ugu nugul qallafsanaanta hydrogen, dillaaca daxalka stress, iyo miridhku ka bilaabmay xayndaabka madaxa iyo gidaarada godka hex.

Koofiyadaha Madaxa Socket Socket-Dacromet

daahan Dacromet - non-electrolytic ah zinc-aluminium flake nidaamka lagu qeexay ISO 10683 iyo ASTM F1136 - si sax ah ayuu wax uga qabtaa daciifnimadan. Filim khafiif ah oo ah 8-12 μm wuxuu keenaa 720 ilaa 1,000 saacadood oo caabbinta milixda ah marka hore miridhku cas (ASTM B117 NSS), ma abuurto wax khatar ah embrittlement hydrogen inta lagu jiro habaynta, oo waxay ilaalisaa joomatari godka hex saxda ah iyo 6g dulqaadka dunta in boolal koofiyada madaxa godku ay ku xiran yihiin.

2. Bolt Joometry iyo Tilmaamaha Naqshadeynta

Xirmada daboolka madaxa ee godka waa boolal awood buuxda leh oo leh madax cylindrical ah iyo wadne godad hexagon gudaha ah:

Madaxa cylindricalleh a rukuntay dusha wareegsan; dhexroorka madaxa dk ≈ 1.5 × d - qiyaas ahaan 30-40% ka yar bool madax lix geesood ah oo isku le'eg, taas oo u oggolaanaysa qaab-dhismeedyo isku-dhafan oo isku dhow;
Madax-ilaa-shank galleyda, aagga kala-guurka ee daalka-muhiimka ah halkaas oo diiradda saaraya walaaca ay ugu badan tahay;
Dul buuxa ama dun qayb ah(shanka jilicsan) qaababka; biraha qayb ahaan-xadhkaha ah waxay dhigaan diyaaradda xiirta ee shank aan xadhig lahayn si ay u sarreeyaan awoodda dhogorta;
Kala duwanaanshaha dhibcaha: siman (chamfered) heerka dhibic; barta eygaiyo barta kootada goobta iyo hawlaha qufulka.

Marka la barbar dhigo boolal hex, SHCS waxay dhalisaa sare horudhac waayo isku mid torque mahad wadista godka wax ku ool ah, oo ay ku rakiban furayaasha hex, wrenches torque, ama darawallada hex ku shaqeeya - iyaga ka dhigaya boolal caadiga ah ee qalabka mashiinka, caaryada irbado, manifolds haydarooliga, jigs iyo qalabka, iyo robotics.

3. Isbarbardhigga Waxqabadka Daxalka

Dahaarka fasalka 8.8-12.9 SHCS	Dhumucda	Buufin milix ah ilaa miridhku cas (ASTM B117)	Khatarta qulqulka hydrogen-ka	Xusuusin
Okssaydh madow (madow), saliid	< 1 μm	< 24 saac	Midna	Qurxinta kaliya; saliiddu way dhaqdaa
Zinc phosphate + saliid	3-5 μm	≈ 48-72 saac	Midna	Dhammaadka "madow" caadiga ah, nolosha xaddidan
Electro-galvanized Zn12, Cr(VI) -free	12 μm	≈ 192 saac	Sare (12.9 laguma talin)	Socket iyo dunta oo khafiif ah
Zinc-nickel alloy electro-plate	8-12 μm	≈ 480-720 saac	Dhexdhexaad	Qiimaha sare; waxay u baahan tahay dubo ka dib
Dacromet DAC 320 (Fasalka 2)	8 μm	≈ 720 saac	Dhab ahaantii midna	Cawlan qalin ah
Dacromet DAC 500 / madow	10-12 μm	≈ 1,000 saac	Dhab ahaantii midna	Dhammaadka madow wuxuu u dhigmaa taxanaha madow

6. Heerarka iyo Badeecada Caadiga ah

Heerarka muhiimka ah: ISO 4762 / DIN 912 (boolasha koofiyada madaxa godka), ISO 898-1 (qalabka farsamada), ISO 10683:2018 (dahaadhka zinc flake non-electrolytic), ASTM F1136, ASTM B117, ISO 4042 (electrolating iyo HE) DIN 267-28 iyo GB/T 70.1 / GB/T 5267.3.

7. Codsiyada iyo Hagidda Xulashada

1.Match daahan xoog: fasalka 10.9 iyo 12.9 boolal, ku adkeyso on flake zinc non-electrolytic (Dacromet / Geomet) si loo baabi'iyo embrittlement hydrogen;

2.Beddel madow oksaydh si caqli ah: sheeg Dacromet madow marka macaamiishu rabaan muuqaalka madow ee ilaalinta miridhka dhabta ah;

3.Verify fasalka daahansaacadaha NSS (DAC 320 ≈ 720 h; DAC 500 ≈ 1,000 h) oo codso warbixinta tijaabada soo saaraha daahan;

4.Xaqiiji Cr (VI) -ku-wareejin bilaash ah(chromium trivalent) ee waafaqsan RoHS/ELV;

5. Hubi xogta khilaafka: hel qodobka lowska iyo warbixinta is-xakamaynta ee isu imaatinka qulqulka-koontaroolada;

6.Dhamee nidaamkaIsticmaal lowska dahaarka leh, weel-dhaqista, iyo gelisyada la taabtay ee kartida ku habboon si aad uga fogaato xirmooyinka isku dhafan ee suurtagalka ah.

8. Gabagabo

Dacromet-dahaarka daboolka daboolka madaxa ayaa mideeya farsamooyinka farsamada ee boolalyada ujeeddooyinka guud ee ugu xooggan - madaxyo isku dhafan oo isku dhafan, wadiiqooyin hex ah oo hufan, karti sare oo horudhac ah - oo leh nidaam daahan oo loo habeeyay si sax ah dhibcahooda daciifka ah: ma jiro hydrogen embrittlement on 12.9 birta, daboolka galay godka, iyo goobaha is-xakamaynta iyo ka-hortagga goobaha is-xakamaynta. xasiloonida khilaaf ee isu-ururinta saxda ah. Si sax ah loo cayimay, waxay keenaan 720-1,000 saacadood buufin milix ah filim 8-12 μm ah, oo waxay keenaan mugdi, muuqaal matte ah oo boolal madaw ah oo keenaya adeeg difaac-celin dhab ah.

Ma Hayso. Xiga.
