4. GB/T 5783-2016 "iHexagon head bolts with full thread"
Umahluko ophambili phakathi kweebholithi ezine eziqhele ukusetyenziswa zezi zilandelayo:
1. Ubude bomsonto obahlukeneyo:
Ubude bomsonto webholithi bungumsonto opheleleyo kunye nomsonto ongagcweleyo.
Phakathi kwezi 4 iibholiti ezisetyenziswa ngokuqhelekileyo
I-GB/T 5780-2016 "I-Hexagon Head Bolts Class C" kunye ne-GB / T 5782-2016 "Iibhotshi zeHexagon Head" azikho iibholiti ezipheleleyo.
I-GB/T 5781-2016 "I-Hexagon Head Bolts Full Thread Class C" kunye ne-GB/T 5783-2016 "I-Hexagon Head Bolts Full Thread" ziyi-bolts ezigcweleyo.
I-GB/T 5781-2016 "I-Hexagon Head Bolts Full Thread Grade C" iyafana ne-GB/T 5780-2016 "I-Hexagon Head Bolts iBanga C" ngaphandle kokuba imveliso yenziwe ngentambo epheleleyo.
I-GB/T 5783-2016 "Iibholiti zeHexagon ezinentambo epheleleyo" iyafana ne-GB/T 5782-2016 "i-Hexagon head bolts" ngaphandle kokuba imveliso yenziwe ngentambo epheleleyo kunye nobude obucacileyo bobude obukhethiweyo bufikelela 200mm.
Ngoko ke, kolu hlalutyo lulandelayo, kuyimfuneko kuphela ukuxoxa ngomahluko phakathi kwe-GB / T 5780-2016 "I-Hexagon Head Bolts Class C" kunye ne-GB / T 5782-2016 "I-Hexagon Head Bolts".
2. Amanqanaba emveliso ahlukeneyo:
Amabakala emveliso yeebholithi ahlulwe abe ngamabakala A, B noC.Ibakala lemveliso lichongwa ngumlinganiselo wokunyamezela.Ibakala lelona lichanekileyo, kwaye ibakala C lelona lichanekileyo.
I-GB/T 5780-2016 "i-Hexagon head bolts C grade" ichaza iibholithi ze-C ezichanekileyo.
I-GB/T 5782-2016 "i-Hexagon head bolts" ichaza iibholithi ezinebakala A kunye nebakala B ngokuchanekileyo.
Kumgangatho we-GB/T 5782-2016 "Hexagon Head Bolts", iBakala A lisetyenziselwa iibholiti ezine-d=1.6mm～24mm kunye ne-l≤10d okanye l≤150mm (ngokwexabiso elincinci);IBanga B lisetyenziselwa iibholithi ezine-d>24mm okanye iiBolt ezino-l>10d okanye l>150mm (nokuba yeyiphi encinci).
Ngokomgangatho wesizwe we-GB/T 3103.1-2002 "IiBolts zokunyamezelana, izikrufu, ii-Studs kunye neeNuts ze-Fasteners", ibakala langaphandle lokunyamezela imisonto yeebholiti ngebakala A no-B ngokuchanekileyo ngu-"6g";Inqanaba lokunyamezela kwintambo yangaphandle "8g";amanye amanqanaba okunyamezelwa kwe-dimensional of bolts ahluka ngokuchaneka kwamabakala A, B, no-C.
3. Iimpawu ezahlukeneyo zoomatshini:
Ngokwamalungiselelo omgangatho wesizwe we-GB/T 3098.1-2010 "IiPropati zeMechanical of Fasteners Bolts, Screws and Studs", iipropathi zomatshini zeebholithi ezenziwe ngentsimbi yekhabhoni kunye nentsimbi yealloy phantsi komqathango wokusingqongileyo we-10 ℃ ~ 35 ℃ Kukho amanqanaba ali-10, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9, 12.9.
Ngokwamalungiselelo omgangatho wesizwe we-GB/T 3098.6-2014 "IiPropati zeMechanical of Fasteners - iiBolts zentsimbi, iiScrews kunye ne-Studs", phantsi kwemeko yobungakanani bendawo ye-10℃～35℃, amabakala okusebenza kweebholiti ezenziwe ngezinto ezingenasici. iintsimbi zezi zilandelayo:
Iibholiti ezenziwe nge-austenitic stainless steels (kubandakanya i-A1, i-A2, i-A3, i-A4, amaqela e-A5) aneeklasi zepropathi yomatshini 50, 70, 80. (Qaphela: Ibakala lepropathi yomatshini yokumakishwa kweebholiti zensimbi ezingenasici iqukethe iinxalenye ezimbini, inxalenye yokuqala iphawula iqela lentsimbi, kwaye inxalenye yesibini ibonisa ibakala lokusebenza, ihlukaniswe ngamadashi, njenge-A2-70, efanayo ngezantsi)
Iibholiti ezenziwe nge-C1 yeqela le-martensitic insimbi engenasici inamabakala epropathi yomatshini we-50, i-70, kunye ne-110;
Iibholiti ezenziwe nge-C3 iqela le-martensitic insimbi engenasici ineklasi yepropathi yomatshini ye-80;
Iibholiti ezenziwe nge-C4 iqela le-martensitic insimbi engenasici inamabakala epropathi yomatshini we-50 kunye ne-70.
Iibholiti ezenziwe nge-F1 martensitic stainless steels zineepropathi ze-mechanical grade 45 kunye ne-60.
Ngokomgangatho wesizwe we-GB/T 3098.10-1993 "Iipropathi zeMechanical of fasteners - Iibholiti, izikrufu, izikhonkwane kunye namandongomane enziwe ngesinyithi esingenawo intsimbi":
Iimpawu zemishini yeebholiti ezenziwe ngobhedu kunye ne-alloys zethusi zezi: CU1, CU2, CU3, CU4, CU5, CU6, CU7;
Iimpawu zemishini yeebholiti ezenziwe nge-aluminium kunye ne-aluminium alloys yile: AL1, AL2, AL3, AL4, AL5, AL6.
Umgangatho kazwelonke we-GB / T 5780-2016 "Ii-Hexagon Head Bolts" ifanelekile kwi-C grade hexagon head bolts ene-thread specifications M5 ukuya ku-M64 kunye namabakala okusebenza 4.6 no-4.8.
Umgangatho kazwelonke we-GB/T 5782-2016 "i-Hexagon head bolts" ifanelekile kwiinkcukacha zentambo M1.6～M64, kwaye amabakala okusebenza angama-5.6, 8.8, 9.8, 10.9, A2-70, A4-70, A2-50, I-A4-50, iBanga A kunye ne-B hex iibholiti zentloko ze-CU2, CU3 kunye ne-AL4.
Oku ngasentla ngumahluko ophambili phakathi kwezi 4 iibholiti ezisetyenziswa ngokuqhelekileyo.
Kwizicelo ezisebenzayo, iibholiti ezipheleleyo zingasetyenziselwa endaweni yeebholiti ezingenayo i-threaded, kwaye i-bolts yezinga eliphezulu linokusetyenziswa endaweni ye-low-performance grade bolts.
Nangona kunjalo, iibholiti ezipheleleyo zenkcazo efanayo zibiza kakhulu kunee-bolts ezingenayo imisonto epheleleyo, kwaye amabakala asebenza kakhulu abiza kakhulu kunamabakala aphantsi.
Ngoko ke, kwiimeko eziqhelekileyo, iibholiti kufuneka zikhethwe ngokweemfuno zangempela, kwaye kuphela kwiimeko ezikhethekileyo kufuneka "zithathe indawo yazo zonke iimpazamo" okanye "zitshintshe iindawo eziphakamileyo kunye nezisezantsi".
