Kukho ama-4 asetyenziswayo asetyenziswayo nge-hexagon bolts:
I-1. GB / T 5780-2016 "I-Hexagon ye-Bolts Clalts C"
I-2. GB / T 5781-2016 "I-Hexagon entloko yeBanga leQhinga le-CP"
I-3. GB / T 5782-2016 "I-Hexagon entloko"
I-4. GB / T 5783-2016 "I-hexagon entloko ngentambo epheleleyo"
Umahluko ophambili phakathi kwezona zixhobo zine zisetyenziswa ziqhelekileyo zezi zilandelayo:
1. Ubude obahlukeneyo
Ubude bentambo buyintambo epheleleyo kunye nentambo engapheliyo.
Phakathi kwezi ntlobo ze-4 eziqhelekileyo ezisetyenzisiweyo
I-GB / T 5780-2016 "I-Hexagon entloko ye-Bolts C" kunye ne-GB / T 5782 "
I-GB / T 5781-2016 "I-Hexagon entloko I-Bolts I-Threyiy yeThutyana C" kunye ne-GB / T 5783-2016 "-2016 "i-bolts egcweleyo" zii-bolts ezigcweleyo "zinebhotile egcweleyo.
I-GB / T 5781-2016 "I-Hexagon entloko iBanga le-Tored Ibakala C" lilingana ne-GB / T 5780 "I-BOLTS IBAKALA IBAKALA C" Ngaphandle kokuba imveliso yenziwa ngentambo epheleleyo.
I-GB / T 5783-2016 "I-Hexagon entloko yentambo epheleleyo" iyafana ne-GB / T 5782 "
Ke ngoko, kolu hlalutyo lulandelayo, kuyimfuneko nje ukuxoxa ngomehluko phakathi kwe-GB / T 5780 "I-BOLTS ye-Bolts Classi Classi Clos C" kunye ne-GB / T 5782 "I-GOLTS entloko".
2. Amabakala eMveliso eyahlukeneyo:
Amabakala emveliso aqhekezwe abe a, b kunye ne-C. Ibakala lemveliso limiselwe bubukhulu be-demeleza. Ibanga lelona mali lichanekileyo, kwaye le lelona lichanekileyo.
I-GB / T 5780-2016 "I-Hexagon entloko yeBanga leBanga" ichaza i-CALTS yeBanga le-CALT.
I-GB / T 5782-2016 "I-Hexagon entloko" icacisa ii-bolts ngenqanaba lokuchaneka kwenqanaba le-B kunye neBanga leBanga.
Kwi-GB / T 5782-2016 "Umgangatho we-Bolts" we-hexagon helts, iBakala A isetyenziselwa ii-bolts nge-D = 1.6mm ~ i-24mm ~ i-24mm kwaye i-L≤150m (ngokwexabiso elincinci); IBakala B lisetyenziselwa iibhotile nge-D> 24mm okanye ii-bolts nge-L> 10D okanye i-15D okanye i-150mm (nayiphi na incinci).
Ngokutsho kwe-National GB / T 3103.1002 "Iimbolo zokunyamezelana, isikali, izitya zokutya kwe-BOLTS" Inqanaba lokunyamezela komsonto lwangaphandle "8G"; Amanye amanqanaba onyamezelo oxinzelelo lwee-bolts ayahluka ngokobunyani be-A, B, neCAQO.
I-3. Iipropathi ezahlukeneyo zoomatshini:
According to the provisions of the national standard GB/T 3098.1-2010 "Mechanical Properties of Fasteners Bolts, Screws and Studs", the mechanical properties of bolts made of carbon steel and alloy steel under the condition of environmental dimension of 10 ℃ ~ 35 ℃ There are 10 levels, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9, 12.9.
Ngokwezixhobo ze-GB yeSizwe / i-3098.6-2014 "IiPropathi zoMatshini weStaints, ii-bolts zentsimbi ezingenasiphelo ze-10 ℃ ~ 35 ~, amabanga entsebenzo yeentsimbi ezenziweyo ngolu hlobo lulandelayo:
I-bolts eyenziwe ngamanqindi angenasiseko (kubandakanya i-A1, i-A2, i-A3, i-A5, inxalenye yesibini ye-Staines iphawula amacandelo amabini, inxalenye yesibini ye-Staine iphawula i-A2-70, inye ngezantsi)
IiBolts ezenziwe nge-C1 qela le-SEARTINITIONITIONITION I-STAEN EYINTONI AMANZI AMANQAKU AMAFIMA angama-50, 70, ne-110;
IiBolts ezenziwe kwiqela le-C3 Martiaticitic Staional Stainess Staines i-80 yepropathi ye-80;
IiBolts ezenziwe ngeqela le-C4 Martiatication Martional Stainess Stainess ineepropathi zepropathi ezingama-50 nengama-70.
IiBolts ezenziwe nge-F1 Martiaticic Stainess Stains zinezixhobo zoomatshini kumaBanga 45 nowama-60.
Ngokwe-GB yeSizwe iMigangatho ye-GB / T 3098.10-1993
Iipropathi zoomatshini beebhotile ezenziwe ngobhedu kunye nobhedu lwe-calls zezi: Cu1, CU2, CU5, CU5, CU6, CU6;
Iipropathi zoomatshini beebhotile ezenziwe nge-Aluminium kunye ne-Aluminium Alfs zezi: Al1, AL2, AL4, AL4, AL5, AL5.
I-GB yeSizwe iMigangatho ye-GB / T 5780-2016 "iklasi yeklasi ye-Chexagon" ilungele iibhloko zentloko ye-CAXGAGON "kunye ne-M64 kunye ne-4.8.
I-A20 ye-Hexagon entloko "ilungele i-Tuorications ye-M1.6 ~ M64, i-A20, i-A2-70, iBa2, i-A4-50, i-A2 kunye ne-AL4 kunye ne-AL4.
Oku kungasentla ngumahluko ophambili phakathi kwezi ziboli zi-4 zisetyenziswayo.
Kwizicelo ezisebenzayo, i-bolta egcwele ngokupheleleyo inokusetyenziswa endaweni yeebhotile ezingekho ngokupheleleyo, kwaye iBanga lokuSebenza eliNtloko lingasetyenziswa endaweni yeebhedi zenqanaba lokuqhuba eliphantsi.
Nangona kunjalo, iibhloko ezigcweleyo ezigcweleyo zenkcazo efanayo zibiza kakhulu kunezilonda ezingezo nyameko, kwaye amabakala okusebenza aphezulu ayabiza kakhulu kunabangamabanga aphantsi.
Ke ngoko, kwizihlandlo eziqhelekileyo, iibhloko kufuneka zikhethwe ngokweemfuno zezoqobo, kwaye kuphela kwizihlandlo ezikhethekileyo "kufuneka zithabathe indawo zonke iimpazamo" okanye "zithabathe indawo ephezulu kunye neLows".
Ixesha lokuposa: Oct-20 ukuya ku-2022
