GB/T 5781-2016 "Hexagon Head Bolts Full Thread Grade C" yakafanana neGB/T 5780-2016 "Hexagon Head Bolts Grade C" kunze kwekuti chigadzirwa chacho chinogadzirwa neshinda yakazara.
GB/T 5783-2016 "Hexagon head bolts with full thread" yakafanana neGB/T 5782-2016 "Hexagon head bolts" kunze kwekuti chigadzirwa chacho chakagadzirwa neshinda yakazara uye hurefu hwezita hwehurefu hunodiwa hunosvika. 200mm.
Nokudaro, mukuongorora kunotevera, zvinongodiwa chete kukurukura musiyano pakati peGB / T 5780-2016 "Hexagon Head Bolts Kirasi C" uye GB / T 5782-2016 "Hexagon Head Bolts".
2. Zvigadzirwa zvakasiyana siyana:
Magiredhi echigadzirwa emabhoti akakamurwa kuita A, B uye C mamakisi. Chigadzirwa chegiredhi chinotarirwa nehukuru hwekushivirira. Giredhi ndiro rakanyatsojeka, uye giredhi reC ndiro rinenge risiri rechokwadi.
GB/T 5780-2016 "Hexagon head mabhaudhi C giredhi" inotaura mabhaudhi eC giredhi chaiwo.
GB/T 5782-2016 "Hexagon head bolts" inotaura mabhaudhi ane giredhi A uye giredhi B nemazvo.
Mune GB/T 5782-2016 "Hexagon Head Bolts" chiyero, Giredhi A rinoshandiswa mabhaudhi ane d=1.6mm～24mm uye l≤10d kana l≤150mm (maererano neukoshi hudiki); Giredhi B rinoshandiswa mabhaudhi ane d>24mm kana maBolt ane l>10d kana l>150mm (chero idiki).
Zvinoenderana neiyo yenyika standard GB/T 3103.1-2002 "Tolerance Bolts, Screws, Studs and Nuts for Fasteners", iyo yekunze shinda yekushivirira giredhi remabhaudhi ane giredhi A uye B nemazvo ndeye "6g"; Chiyero chekushivirira chetambo yekunze ndeye "8g"; mamwe mazinga ekushivirira mazinga emabhoti anosiyana zvichienderana nekururama kweA, B, uye C mamakisi.
3. Different mechanical properties:
Zvinoenderana nezvinodiwa zveNational standard GB/T 3098.1-2010 "Mechanical Properties yeFasteners Bolts, Screws and Studs", iyo mechaniki zvivakwa zvemabhoti akagadzirwa nekabhoni simbi uye alloy simbi pasi pemamiriro ezvakatipoteredza dimension ye10 ℃ ~ 35 ℃. Pane mazinga gumi, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9, 12.9.
Zvinoenderana nezvinodiwa zveNational standard GB/T 3098.6-2014 "Mechanical Properties of Fasteners - Stainless Steel Bolts, Screws and Studs", pasi pemamiriro ezvakatipoteredza dimension ye10 ℃～35 ℃, mamakisi ekuita emabhoti akagadzirwa nesimbi. simbi ndezvizvi:
Mabhaudhi akagadzirwa neaustenitic stainless steels (kusanganisira A1, A2, A3, A4, A5 mapoka) ane mechanical property makirasi 50, 70, 80. (Cherechedza: The mechanical Property grade marking of stainless simbi mabhaudhi ine zvikamu zviviri, chikamu chekutanga maki. boka resimbi, uye chikamu chechipiri chinoratidza giredhi rekuita, rakapatsanurwa nemadheshi, akadai seA2-70, akafanana pazasi)
Mabhoti akagadzirwa neC1 group martensitic Stainless steel ane mechanical property mamakisi e50, 70, uye 110;
Mabhoti akagadzirwa neC3 boka martensitic simbi isina tsvina ine mechanical property class ye80;
Mabhoti akagadzirwa neC4 group martensitic Stainless simbi ane mechanical property mamakisi e50 ne70.
Mabhaudhi akagadzirwa neF1 martensitic Stainless simbi ane michina zvivakwa mamakisi 45 ne60.
Zvinoenderana neyakajairwa yenyika GB/T 3098.10-1993 "Mechanical properties yezvisungo - Mabhaudhi, screws, studs uye nzungu dzakagadzirwa nesimbi isina-ferrous":
Iyo mechanical properties yemabhoti yakagadzirwa nemhangura nemhangura alloys ndeiyi: CU1, CU2, CU3, CU4, CU5, CU6, CU7;
Iyo mechanic properties yemabhaudhi akagadzirwa nealuminium uye aruminiyamu alloys ndeaya: AL1, AL2, AL3, AL4, AL5, AL6.
Iyo yenyika standard GB/T 5780-2016 "Kirasi C Hexagon Head Bolts" inokodzera C giredhi hexagon mabhaudhi emusoro ane shinda yakatarwa M5 kusvika M64 uye ekuita mamakisi 4.6 uye 4.8.
Iyo yenyika standard GB/T 5782-2016 "Hexagon head bolts" inokodzera tambo yakatarwa M1.6～M64, uye mamakisi ekuita ari 5.6, 8.8, 9.8, 10.9, A2-70, A4-70, A2-50, A4-50, Giredhi A uye B hex musoro mabhaudhi eCU2, CU3 uye AL4.
Zviri pamusoro apa ndiwo musiyano mukuru pakati pemabhaudhi mana anowanzo shandiswa.
Mumashandisirwo anoshanda, mabhoti akazara-akazara anogona kushandiswa panzvimbo yeasina-akazara-akazara mabhaudhi, uye yakakwirira-yekuita giredhi mabhoti anogona kushandiswa pane yakaderera-inoshanda giredhi mabhoti.
Zvisinei, mabhaudhi akazara-akazara ezvinyorwa zvakafanana anodhura kupfuura asina-akazara-akazara mabhaudhi, uye yakakwirira-yekuita mamakisi inodhura kupfuura yakaderera-kuita mamakisi.
Naizvozvo, muzviitiko zvakajairika, mabhaudhi anofanirwa kusarudzwa zvinoenderana nezvinodiwa chaizvo, uye chete muzviitiko zvakakosha zvinofanirwa "kutsiva zvikanganiso zvese" kana "kutsiva zvakakwirira nekudzika".
