Pali mabawuti anayi a hexagon omwe amagwiritsidwa ntchito kwambiri:
1. GB/T 5780-2016 "Hexagon Head Bolts Class C"
2. GB/T 5781-2016 "Mabawuti akumutu a hexagon okhala ndi ulusi wonse C kalasi"
3. GB/T 5782-2016 "Hexagon Head Bolts"
4. GB/T 5783-2016 "Mabawuti a hexagon okhala ndi ulusi wonse"
Kusiyana kwakukulu pakati pa mabawuti anayi omwe amagwiritsidwa ntchito kwambiri ndi awa:
1. Utali wosiyana wa ulusi:
Kutalika kwa ulusi wa bawuti ndi ulusi wonse komanso ulusi wosadzaza.
Pamwambapa 4 mabawuti omwe amagwiritsidwa ntchito kwambiri
GB/T 5780-2016 "Hexagon Head Bolts Class C" ndi GB/T 5782-2016 "Hexagon Head Bolts" ndi mabawuti osadzaza ulusi.
GB/T 5781-2016 "Hexagon Head Bolts Full Thread Class C" ndi GB/T 5783-2016 "Hexagon Head Bolts Full Thread" ndi mabawuti odzaza ulusi.
GB/T 5781-2016 "Hexagon Head Bolts Full Thread Grade C" ndi yofanana ndi GB/T 5780-2016 "Hexagon Head Bolts Grade C" kupatula kuti mankhwalawa amapangidwa ndi ulusi wonse.
GB/T 5783-2016 "Hexagon head bolts with full thread" ndi zofanana ndi GB/T 5782-2016 "Hexagon head bolts" kupatula kuti mankhwalawo amapangidwa ndi ulusi wathunthu ndipo kutalika kwadzina kwa kutalika komwe kumakonda kuli mpaka 200 mm.
Choncho, pakuwunika kotsatiraku, ndikofunikira kukambirana kusiyana pakati pa GB / T 5780-2016 "Hexagon Head Bolts Class C" ndi GB / T 5782-2016 "Hexagon Head Bolts".
2. Zosiyanasiyana zamagulu:
Zogulitsa za ma bolts zimagawidwa m'makalasi A, B ndi C. Gulu la mankhwala limatsimikiziridwa ndi kukula kwa kulolerana. Giredi ndi yolondola kwambiri, ndipo giredi C ndiyolondola kwambiri.
GB/T 5780-2016 "Hexagon head bolts C grade" imatchula mabawuti olondola a giredi C.
GB/T 5782-2016 "Mabawuti akumutu" amatchula mabawuti okhala ndi giredi A komanso giredi B molondola.
Mu muyezo wa GB/T 5782-2016 "Hexagon Head Bolts", Gulu A imagwiritsidwa ntchito pamaboti okhala ndi d=1.6mm～24mm ndi l≤10d kapena l≤150mm (malinga ndi mtengo wocheperako); Gulu B amagwiritsidwa ntchito pa mabawuti okhala ndi d> 24mm kapena Bolts okhala ndi l> 10d kapena l> 150mm (chilichonse chaching'ono).
Malinga ndi muyezo wadziko lonse wa GB/T 3103.1-2002 "Tolerance Bolts, Screws, Studs and Nuts for Fasteners", ulusi wakunja wololera ma bawuti okhala ndi giredi A ndi B mwatsatanetsatane ndi "6g"; Kulekerera kwa ulusi wakunja ndi "8g"; Miyezo ina yololera ma bawuti imasiyanasiyana malinga ndi kulondola kwa magiredi A, B, ndi C.
3. Zosiyanasiyana zamakina:
Malinga ndi zomwe National Standard GB/T 3098.1-2010 "Mechanical Properties of Fasteners Bolts, Screws and Studs", makina amakina opangidwa ndi chitsulo cha kaboni ndi aloyi chitsulo pansi pa chikhalidwe cha chilengedwe cha 10 ℃ ~ 35 ℃ Pali magawo 10, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9, 12.9.
Malinga ndi zomwe National Standard GB/T 3098.6-2014 "Mechanical Properties of Fasteners - Stainless Steel Bolts, Screws and Studs", pansi pa chikhalidwe cha chilengedwe cha 10 ℃～35 ℃, magwiridwe antchito a mabawuti opangidwa ndi zosapanga dzimbiri. zitsulo ndi izi:
Maboti opangidwa ndi zitsulo zosapanga dzimbiri za austenitic (kuphatikiza A1, A2, A3, A4, A5 magulu) ali ndi makalasi opangira zida zamakina 50, 70, 80. (Zindikirani: Kuyika chizindikiro kwa zitsulo zosapanga dzimbiri kumakhala ndi magawo awiri, gawo loyamba limalemba. gulu lachitsulo, ndipo gawo lachiwiri likuwonetsa kalasi yamasewera, yolekanitsidwa ndi mizere, monga A2-70, zomwezi pansipa)
Maboti opangidwa ndi C1 gulu martensitic zitsulo zosapanga dzimbiri ali ndi makina amtundu wa 50, 70, ndi 110;
Maboti opangidwa ndi C3 gulu martensitic zitsulo zosapanga dzimbiri ali ndi makina amtundu wa 80;
Maboti opangidwa ndi C4 gulu martensitic zitsulo zosapanga dzimbiri ali ndi makina amtundu wa 50 ndi 70.
Maboti opangidwa ndi F1 martensitic zitsulo zosapanga dzimbiri ali ndi makina amagiredi 45 ndi 60.
Malinga ndi National Standard GB/T 3098.10-1993 "Mechanical properties of fasteners - Bolts, screws, studs ndi mtedza zopangidwa ndi zitsulo zopanda chitsulo":
The makina zimatha mabawuti opangidwa ndi mkuwa ndi kaloti zamkuwa ndi: CU1, CU2, CU3, CU4, CU5, CU6, CU7;
Makina opangira ma bolts opangidwa ndi aluminiyamu ndi ma aluminiyamu aloyi ndi: AL1, AL2, AL3, AL4, AL5, AL6.
Miyezo ya dziko lonse ya GB/T 5780-2016 "Maboliti a Mutu C a Hexagon" ndi oyenera ma bawuti amutu a C giredi hexagon okhala ndi ulusi wa M5 mpaka M64 komanso magiredi 4.6 ndi 4.8.
National standard GB/T 5782-2016 "Hexagon head bolts" ndiyoyenera kutengera ulusi M1.6 ~M64, ndipo magiredi ochita ndi 5.6, 8.8, 9.8, 10.9, A2-70, A4-70, A2-50, A4-50, Grade A ndi B hex head bolts a CU2, CU3 ndi AL4.
Pamwambapa pali kusiyana kwakukulu pakati pa mabawuti 4 omwe amagwiritsidwa ntchito kwambiri.
Muzochita zogwiritsidwa ntchito, ma bolt odzaza amatha kugwiritsidwa ntchito m'malo mwazitsulo zopanda ulusi, ndipo ma bolts apamwamba amatha kugwiritsidwa ntchito m'malo mwazitsulo zotsika kwambiri.
Komabe, ma bolts okhala ndi ulusi wamtundu womwewo ndi okwera mtengo kuposa ma bolts opanda ulusi, ndipo magiredi apamwamba ndi okwera mtengo kuposa magiredi otsika.
Choncho, muzochitika zachilendo, mabawuti ayenera kusankhidwa malinga ndi zosowa zenizeni, ndipo pokhapokha pazochitika zapadera ziyenera "kulowa m'malo mwa zolakwika zonse" kapena "m'malo okwera ndi otsika".
