Dacromet Hex Socket Bolts: Dahaarka Sare ee Ka-hortagga Daxalka wuxuu la kulmaa Naqshad Xijin oo Sax ah
2026-07-27
Dacromet hex socket bolts waxay ka dhigan yihiin isku dhafka laba teknooloji xiraha muhiimka ah: Dacromet-ka waxqabadka sare ee ka-hortagga daxalka iyo joomatari godka-madaxa cylindrical (Allen). Si wada jir ah, waxay keenaan xal xajin ah oo u adkeysanaya jawi aad u wasakhaysan iyagoo awood u siinaya rakibaad sax ah oo xoog badan, taasoo ka dhigaysa lama huraan xagga baabuurta, badda, dhismaha, iyo codsiyada mashiinnada culus ee adduunka oo dhan.
1. Dacromet Technology Coating
Dacromet waa nidaam daahan biyo-ku-salaysan oo asal ahaan loo sameeyay kaarboonka iyo xidhayaasha birta-la'aanta ah. Si ka duwan zinc-ga elektiroonigga ah ee caadiga ah, Dacromet waxay shaqaaleysiisaa hannaan kiimiko ah oo aan chromium-free (ama chromium-hooseeya) kaas oo sameeya xannibaad adag oo lakabyo badan oo zinc iyo aluminium ah. Natiijadu waa dhamaystir qalin-cawlan oo gaar ah oo isku dara dhexdhexaadnimada bilicda iyo waxqabadka ilaalinta gaarka ah.
Saddexda lakab ayaa si isku mid ah u shaqeeya si ay u bixiyaan ilaalin dhammaystiran:
Lakabka salka flake Zinc-aluminium - waxa uu bixiyaa ilaalin allabaryo (cathodic), iyada oo doorbidaysa in la ilaaliyo substrate-ka birta ee hoose, halka jajabyada aluminiumku ay ku daraan ilaalinta xannibaadda.
Lakabka dhexe ee Passivation – waa filim chromate/silicate ah oo aan organic ahayn kaas oo xidha qaab dhismeedka birta, iska caabinta buufinta milixda, weerarka kiimikaad, iyo kulayl ka fog dheesha zinc caadiga ah.
Jaakadaha shaambada dabiiciga ah ee ugu sarreeya (ikhtiyaar) - waxay xoojisaa waxqabadka ka-hortagga qulqulka iyo iska caabinta cimilada, iyada oo soo saarta muuqaal qalin-cawlan oo joogto ah oo leh iskudhafan hoose.
Shaxda 1. Isbarbardhigga Iska caabinta Daxalka (Tijaabada buufinta milixda, NSS)
| Nooca Dahaarka | Saacadaha buufinta milixda | Dhumucda (μm) | Codsiga caadiga ah |
| Dacromet | ≥ 1,000 - 3,000 | 6 – 10 | Marine / baabuur |
| Ruspert | ≥ 1,000 - 3,000 | 3 – 5 | Banaanka / badda |
| Daahinta aluminiumka Zn-Ni | ≥ 720 - 1,000 | 8 – 12 | Baabuur |
| Dajinta caadiga ah ee Zn | 96 - 240 | 5 – 8 | Gudaha / guud |
2. Hex Socket Bolts
Xirmooyinka godka hex, oo sidoo kale loo yaqaanno biraha madaxa godka ama Allen bolts, ayaa leh madax cylindrical ah oo leh darawal laba geesood ah oo gudaha ah. Joometry Tani waxay u ogolaanaysaa gudbinta qulqulka sare leh astaan madax ka yar marka la barbar dhigo bolts hex dibadda, samaynta iyaga ku habboon codsiyada leh fasax xaddidan ama halka daadsan, muuqaal nadiif ah loo baahan yahay.
Tilmaamaha naqshadeynta muhiimka ah waxaa ka mid ah:
Madaxa cylindrical leh hex drive gudaha - aqbala furayaasha hex-ga caadiga ah ee rakibaadda qulqulka sare leh oo leh madax ka soo bixid yar; Cabbirrada wadista waxay waafaqsan yihiin ISO 2936 ama ASME B18.3.
Dul-dugan oo dhammaystiran ama qayb ka mid ah-- noocyada kala duwan ee xadhig-buuxa ah ayaa u qaybiya culayska si siman inta lagu jiro dhererka ku hawlan; Kala duwanaanshiyaha dunta qayb ka mid ah ayaa bixiya shank aan la faafin oo ka xoog badan codsiyada xiiridda.
Biraha daawaha ah ee xoogga badan (8.8 / 10.9 / 12.9) - Heerarka kulaylka lagu daweeyay waxay xaqiijiyaan awoodda xajinta ilaa 1,220 MPa, oo ku habboon culeysyada firfircoon iyo kala-goysyada muhiimka ah.
Dhammaystirka dusha sare ee Dacromet - waxa uu bixiyaa ≥ 1,000 saacadood oo ilaalinta buufinta milixda ah iyada oo aan la hayn hydrogen, taas oo ka dhigaysa mid ku habboon xirayaasha xoogga sare leh halkaas oo koronto-samayntu aanay ku habboonayn.

| Cabbirka | Thread Dia. (mm) | Dhererka madaxa (mm) | Min. Xoojinta (MPa) | Codsiga caadiga ah |
| M4 | 4 | 4 | 800 | Elektroonik/qalabka |
| M5 | 5 | 5 | 800 | Kulanka iftiinka |
| M6 | 6 | 6 | 800 | Alaabta/mashiinada |
| M8 | 8 | 8 | 800 | Makaanikada / baabuurta |
| M10 | 10 | 10 | 830 | Kala goysyada qaab dhismeedka |
| M12 | 12 | 12 | 830 | Mashiino culus |
3. Kooban
Dacromet hex socket bolts waxay isku daraan iska caabbinta daxalka sare ee nidaamka daahan inorganic Dacromet (gaaritaanka 1,000-3,000 saacadood ee ilaalinta milixda-buufinta iyada oo aan lahayn embrittlement hydrogen) oo leh naqshad heer sare ah, naqshad hoose oo ah bolt godka hex. Isku dhafkan ayaa awood u siinaya in la isku hallayn karo in lagu xidho deegaan baahida loo qabo - laga bilaabo shasis iyo nidaamyada biriiga ilaa dhismayaasha badda iyo qalabka dibadda - iyada oo la ilaalinayo kontoroolka saxda ah ee qulqulka iyo cimri dhererka. Maaddaama warshaduhu ay si sii kordheysa u dalbanayaan xirmooyin isku dheelitiran waxqabadka, badbaadada, iyo cimri dhererka, Dacromet hex socket bolts waxay noqdeen doorashada la doorbido injineerada iyo OEM-yada adduunka oo dhan.
