Kunamabhawodi ama-hexagon ama-4 avame ukusetshenziswa:
1. GB/T 5780-2016 "I-Hexagon Head Bolts Class C"
2. GB/T 5781-2016 "Amabhawodi ekhanda elingu-Hexagon anochungechunge olugcwele lwebanga C"
3. GB/T 5782-2016 "Amabhowodi eHexagon Head"
4. GB/T 5783-2016 "Amabhawodi ekhanda eliyiHexagon anomucu ogcwele"
Umehluko omkhulu phakathi kwamabhawodi amane asetshenziswa kakhulu imi kanje:
1. Ubude bentambo obuhlukile:
Ubude bentambo yebhawudi buyintambo egcwele kanye nentambo engagcwele.
Phakathi kwamabhawodi angu-4 angenhla asetshenziswa kakhulu
I-GB/T 5780-2016 "I-Hexagon Head Bolts Class C" kanye ne-GB/T 5782-2016 "Ama-Hexagon Head Bolts" amabhawodi anentambo engagcwele.
I-GB/T 5781-2016 "I-Hexagon Head Bolts Full Thread Class C" kanye ne-GB/T 5783-2016 "I-Hexagon Head Bolts Uchungechunge Olugcwele" amabhawodi anentambo egcwele.
I-GB/T 5781-2016 "I-Hexagon Head Bolts Full Thread Grade C" iyafana ne-GB/T 5780-2016 "I-Hexagon Head Bolts Grade C" ngaphandle kokuthi umkhiqizo wenziwe ngentambo egcwele.
I-GB/T 5783-2016 "Amabhawodi ekhanda elinguHexagon anentambo egcwele" afana ne-GB/T 5782-2016 "Amabhawodi ekhanda elinguHexagon" ngaphandle kokuthi umkhiqizo wenziwe ngentambo egcwele futhi ubude begama lokucaciswa kobude obuncanyelwayo bufika ku- 200mm.
Ngakho-ke, ekuhlaziyweni okulandelayo, kudingekile kuphela ukuxoxa ngomehluko phakathi kwe-GB/T 5780-2016 "Hexagon Head Bolts Class C" kanye ne-GB/T 5782-2016 "Hexagon Head Bolts".
2. Amabanga emikhiqizo ahlukene:
Amabanga omkhiqizo wamabhawodi ahlukaniswe ngamamaki A, B kanye no-C. Ibanga lomkhiqizo linqunywa usayizi wokubekezelela. Ibanga linembe kakhulu, futhi ibanga elingu-C linembe kancane.
I-GB/T 5780-2016 "Ibanga le-Hexagon head bolts C" ibeka amabhawodi anemba ebangeni elingu-C.
I-GB/T 5782-2016 "Amabhawodi ekhanda elingu-Hexagon" ibeka amabhawodi anemba ibanga A kanye nebanga B.
Esilinganisweni se-GB/T 5782-2016 "Hexagon Head Bolts", IBanga A lisetshenziselwa amabhawodi ano-d=1.6mm～24mm no-l≤10d noma l≤150mm (ngokwenani elincane); Ibanga B lisetshenziselwa amabhawodi ano-d>24mm noma amaBolt ano-l>10d noma l>150mm (noma yikuphi okuncane).
Ngokwendinganiso kazwelonke ye-GB/T 3103.1-2002 "Amabhawudo Okubekezelelana, Izikulufu, Izigxobo kanye Namantongomane Okuqinisa", izinga langaphandle lokubekezelela intambo lamabhawodi anebanga A no-B ngokunemba elithi "6g"; Izinga lokubekezelela intambo yangaphandle "8g"; amanye amaleveli okubekezelela ubukhulu bamabhawodi ayahlukahluka kuye ngokunemba kwamabanga A, B, kanye no-C.
3. Izakhiwo ezihlukile zemishini:
Ngokuya ngezinhlinzeko ze-GB/T 3098.1-2010 ejwayelekile kazwelonke "Mechanical Properties of Fasteners Bolts, Screws and Studs", izakhiwo zemishini zamabhawodi enziwe nge-carbon steel ne-alloy steel ngaphansi kwesimo sobukhulu bemvelo obungu-10 ℃ ~ 35 ℃. Kunamazinga ayi-10, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9, 12.9.
Ngokuya ngezinhlinzeko ze-GB/T ejwayelekile kazwelonke ye-GB/T 3098.6-2014 "Mechanical Properties of Fasteners - Stainless Steel Bolts, Screws and Studs", ngaphansi kwesimo sobukhulu bemvelo obungu-10℃～35℃, amamaki okusebenza wamabhawodi enziwe ngebala. insimbi imi kanje:
Amabhawodi enziwe ngezinsimbi ezingenasici ze-austenitic (okuhlanganisa i-A1, A2, A3, A4, A5 amaqembu) anezigaba zemishini eyimishini engu-50, 70, 80. (Qaphela: Ibanga lendawo yomshini wamabhawudo ensimbi engagqwali linezingxenye ezimbili, ingxenye yokuqala iphawula iqembu lensimbi, futhi ingxenye yesibili iphawula ibanga lokusebenza, ihlukaniswe ngamadeshi, njenge-A2-70, efanayo ngezansi)
Amabhothi enziwe nge-C1 group martensitic insimbi engagqwali anamabanga ezakhiwo zemishini ka-50, 70, no-110;
Amabhothi enziwe nge-C3 group martensitic insimbi engagqwali anesigaba sempahla yemishini engama-80;
Amabhothi enziwe ngensimbi engagqwali ye-C4 yeqembu le-martensitic anezakhiwo eziwumshini amabanga angu-50 no-70.
Amabhawodi enziwe ngezinsimbi ezingenasici ze-martensitic ze-F1 anezakhiwo zemishini amabanga 45 kanye ne-60.
Ngokusho kwe-GB/T ejwayelekile kazwelonke ye-GB/T 3098.10-1993 "Izindawo zokubopha izinsimbi - Amabhulothi, izikulufu, izikhonkwane namantongomane enziwe ngezinsimbi ezingenayo ayoni":
Izakhiwo zemishini yamabholithi enziwe ngethusi ne-alloys yethusi yilezi: CU1, CU2, CU3, CU4, CU5, CU6, CU7;
Izici zemishini zamabhawodi enziwe nge-aluminium ne-aluminium alloys yilezi: AL1, AL2, AL3, AL4, AL5, AL6.
I-GB/T 5780-2016 ejwayelekile kazwelonke "I-Class C Hexagon Head Bolts" ifaneleka kumabhawodi ekhanda angu-hexagon webanga elingu-C anezicaciso zentambo uM5 ukuya ku-M64 kanye namabanga okusebenza angu-4.6 no-4.8.
Izinga kazwelonke ezijwayelekile ze-GB/T 5782-2016 "Amabhawodi angamahexagon" afanele ukucaciswa kochungechunge M1.6～M64, futhi amamaki okusebenza angu-5.6, 8.8, 9.8, 10.9, A2-70, A4-70, A2-50, I-A4-50, iBanga A kanye ne-B hex amabhawodi ekhanda le-CU2, CU3 kanye ne-AL4.
Okungenhla umehluko omkhulu phakathi kwalawa mabhawodi ama-4 asetshenziswa kakhulu.
Kuzinhlelo zokusebenza ezingokoqobo, amabhawudi anentambo egcwele angasetshenziswa esikhundleni samabhawudi angagcwele, futhi amabhawudi ebanga lokusebenza okuphezulu angasetshenziswa esikhundleni samabhawodi ebanga eliphansi lokusebenza.
Kodwa-ke, amabhawodi anentambo egcwele yencazelo efanayo ayabiza kakhulu kunamabhawodi angagcwele, futhi amamaki asebenza kahle kakhulu abiza kakhulu kunamamaki asebenza kancane.
Ngakho-ke, ngezikhathi ezivamile, ama-bolts kufanele akhethwe ngokuvumelana nezidingo zangempela, futhi ngezikhathi ezikhethekile kuphela kufanele "athathe indawo yawo wonke amaphutha" noma "athathe indawo ephezulu ngokuphansi".
