Kunezinhlobo ezi-4 ze-hex nuts ezivame ukusetshenziswa:
1. GB/T 41-2016 “Type 1 Hex Nut Grade C”
2. GB/T 6170-2015 “Type 1 Hex Nut”
3. GB/T 6175-2016 “Type 2 Hex Nuts”
4. GB/T 6172.1-2016 “Hexagon Thin Nut”
Umehluko omkhulu phakathi kwamantongomane amane asetshenziswa kakhulu imi kanje:
1. Ubude bamantongomane buhlukile:
Ngokuya ngezinhlinzeko ze-GB/T 3098.2-2015 ezijwayelekile kazwelonke “Izakhiwo Zemishini Yamantongomane Okubopha”, kunezinhlobo ezintathu zobude bamantongomane:
——Uhlobo 2, inadi eliphakeme: ubude obuncane mmin≈0.9D noma >0.9D;
——Uhlobo 1, inadi elivamile: ubude obuncane mmin≈0.8D;
——Uhlobo 0, nati elincanyana: ubude obuncane bungu-0.45D≤mmin<0.8D.
Qaphela: U-D uwububanzi obujwayelekile bomucu wamantongomane.
Phakathi kwamantongomane amane angenhla avame ukusetshenziswa:
I-GB/T 41-2016 “Type 1 Hex Nut Grade C” kanye ne-GB/T 6170-2015 “Type 1 Hex Nut” amantongomane ajwayelekile oHlobo 1, futhi ubude obuncane bentongomane bungu-mmin≈0.8D.
I-GB/T 6175-2016 “Type 2 Hex Nuts” iwuhlobo lwe-2 high nut, futhi ubude obuncane benati ngu-mmin≥0.9D.
I-GB/T 6172.1-2016 “I-Hexagon Thin Nut” iwuhlobo lwenadi elincanyana elingu-0, futhi ubude obuncane bentongomane bungu-0.45D≤mmin＜0.8D.
2. Amabanga emikhiqizo ahlukene:
Amabanga omkhiqizo wamantongomane ahlukaniswe ngamamaki A, B kanye no-C.Amabanga omkhiqizo anqunywa usayizi wokubekezelela.Ibanga linembe kakhulu futhi ibanga elingu-C linembe kancane.
I-GB/T 41-2016 “Type 1 Hexagon Nuts Grade C” icacisa amantongomane anemba ebangeni C.
I-GB/T 6170-2015 “Type 1 Hexagonal Nuts”, GB/T 6175-2016 “Type 2 Hexagonal Nuts” kanye ne-GB/T 6172.1-2016 “Hexagonal Thin Nuts” ibeka amantongomane anemba ibanga A kanye nebanga B.
Ku-GB/T 6170-2015 “Type 1 Hexagonal Nuts”, GB/T 6175-2016 “Type 2 Hexagonal Nuts” kanye ne-GB/T 6172.1-2016 “Hexagonal Thin Nuts”, Ibanga A lisetshenziselwa amantongomane ano-D≤16mm;Ibanga B lisetshenziselwa amantongomane ano-D>16mm.
Ngokusho kwe-GB/T ejwayelekile kazwelonke ye-GB/T 3103.1-2002 “Ama-Fastener Tolerance Bolts, Screws, Studs and Nuts”, ibanga langaphakathi lokubekezelela intambo le-A-level kanye ne-B-level precision nuts lithi “6H”;Ibanga lokubekezelela intambo yangaphakathi "7H";amamaki okubekezelela obunye ubukhulu bamantongomane ahlukile ngokuya ngokunemba kwamabanga A, B kanye no-C.
3. Amabanga ahlukene wezakhiwo zemishini
Ngokwezinhlinzeko ze-GB/T ejwayelekile kazwelonke 3098.2-2015 “Mechanical Properties of Fastener Nuts”, amabhawodi enziwe ngensimbi ye-carbon steel ne-alloy steel anezinhlobo ezingu-7 zamamaki okusebenza kwemishini ngaphansi kwesimo sobukhulu bemvelo obungu-10°C kuya ku-35. °C.Bangu-04, 05, 5, 6, 8, 10, 12 ngokulandelana.
Ngokuya ngezinhlinzeko ze-GB/T ejwayelekile kazwelonke 3098.15-2014 “Mechanical Properties of Fasteners Stainless Steel Nuts”, lapho ubukhulu bemvelo bungu-10°C kuya ku-35°C, amamaki okusebenza amantongomane enziwe ngensimbi engagqwali acaciswa kanjena. :
Amantongomane enziwe ngensimbi engagqwali ye-austenitic (okuhlanganisa A1, A2, A3, A4, A5 amaqembu) anezakhiwo eziwumshini ezingu-50, 70, 80 kanye no-025, 035, 040. (Qaphela: Ibanga lokusebenza komshini lamantongomane ensimbi engagqwali lakhiwe okubili. izingxenye, ingxenye yokuqala iphawula iqembu lensimbi, kanti ingxenye yesibili iphawula ibanga lokusebenza, ihlukaniswe ngamadeshi, njenge-A2-70, okufanayo ngezansi)
Amantongomane enziwe ngensimbi engagqwali ye-martensitic yeqembu C1 anamamaki empahla yemishini ka-50, 70, 110 no-025, 035, 055;
Amantongomane enziwe ngensimbi engagqwali ye-martensitic yeqembu C3 anezakhiwo zemishini ye-80 ne-040;
Amantongomane enziwe ngensimbi engagqwali ye-martensitic yeqembu C4 anamabanga wempahla eyimishini engu-50, 70 no-025, 035.
Amantongomane enziwe ngensimbi engagqwali yeqembu le-F1 anezakhiwo eziwumshini amabanga angu-45, 60 no-020, 030.
Ngokuya ngezinhlinzeko zezinga likazwelonke le-GB/T 3098.10-1993 “Izakhiwo Zemishini Yokuzibopha – Amabhawudi, Izikulufu, Izikhonkwane Namantongomane Enziwe Ngezinsimbi Ezingezona Insimbi”:
Amantongomane enziwe ngethusi ne-alloys yethusi anamabanga okusebenza kwemishini: CU1, CU2, CU3, CU4, CU5, CU6, CU7;
Amantongomane enziwe nge-aluminium nama-alloys ane-aluminium alloys anamamaki okusebenza ngomshini: AL1, AL2, AL3, AL4, AL5, AL6.
I-GB/T 41-2016 ejwayelekile kazwelonke “Yohlobo 1 I-Hexagon Nut Grade C” isetshenziswa kumantongomane e-hexagon ebangeni C anokucaciswa kwentambo M5 ~ M64 kanye nebanga lokusebenza 5.
I-GB/T 6170-2015 ejwayelekile kazwelonke “Uhlobo 1 lweHexagon Nut” iyasebenza ekucacisweni kochungechunge M1.6~M64, amamaki okusebenza angu-6, 8, 10, A2-70, A4-70, A2-50, A4-50 , CU2 , CU3 kanye ne-AL4 yebanga A kanye ne-B hex nuts.
I-GB/T 6175-2016 “Type 2 Hexagon Nuts” esezingeni likazwelonke iyasebenza kumabhawodi angamahexagon ebanga A kanye nebanga B anezicaciso zentambo M5~M36 kanye namabanga okusebenza 10 nele-12.
Izinga kazwelonke ezijwayelekile ze-GB/T 6172.1-2016 “Hexagon Thin Nut” ziyasebenza ekucacisweni kochungechunge M1.6~M64, amamaki okusebenza angu-04, 05, A2-025, A2-035, A2-50, A4-035, CU2, I-CU3 kanye ne-AL4 yebanga A no-B amantongomane azacile angama-hexagonal.
Ububanzi bobubanzi obujwayelekile obuhambisana nohlobo lwamantongomane kanye nebanga lokusebenza buboniswa kuthebula elingezansi.
Amantongomane ajwayelekile (uhlobo 1) namantongomane aphezulu (uhlobo 2) enziwe ngensimbi ye-carbon steel ne-alloy steel kufanele asetshenziswe nezixhumi zangaphandle ezinentambo etafuleni elilandelayo, futhi amantongomane anamazinga aphezulu okusebenza angashintsha amantongomane afake amamaki okusebenza aphansi.
Amantongomane ajwayelekile (uhlobo 1) asetshenziswa kakhulu.
Amantongomane amade (uhlobo 2) ngokuvamile asetshenziswa ekuxhumekeni okudinga ukuhlakazwa njalo.
Amantongomane azacile (Uhlobo 0) anomthamo ophansi wokuthwala umthwalo kunamantongomane ajwayelekile noma amade, ngakho-ke akufanele adizayinelwe izinto ezivimbela ukukhubeka.
Amantongomane azacile (uhlobo 0) avame ukusetshenziswa ekwakhiweni okulwa nokuxegiswa kwamantongomane akabili.
