Uhlolojikelele Lomkhiqizo Lo mkhiqizo uyintambo ene-hexagon enamandla aphezulu eyakhiwe ngokwe-GB/T 6170-2015 (Uhlobo 1 Lwamantambo E-Hexagon), etholakala ngezigaba zePropathi 8, 10, no-12 ngokwe-ISO 898-2. Intambo inesimo se-hexagon esijwayelekile enentambo ye-metric coarse futhi yakhelwe ukuhlangana namabhawodi anamandla aphezulu ku-Grade 8.8, 10.9, no-12.9 ezinhlelweni zesakhiwo, imishini, nezimboni. Izinga le-GB/T 6170-2015 licacisa amantambo e-hexagon Uhlobo 1 anosayizi wentambo kusuka ku-M1.6 kuya ku-M64, ehlanganisa izigaba zepropathi 6, 8, 10, A2-50, A2-70, A4-50, A4-70, CU2, CU3, ne-AL4, namazinga omkhiqizo A (we-D ≤ 16 mm) no-B (we-D > 16 mm). Izinga lokwamukelwa okuguquliwe kwe-ISO 4032:2012, okuqinisekisa ukuhambisana kobukhulu bamazwe ngamazwe. Uhlobo Lomkhiqizo & Idizayini Isici Incazelo Uhlobo Lomkhiqizo Intambo Ye-Hexagon Uhlobo 1 / Intambo Ye-Hexagon Enamandla Aphezulu Isimo I-Hexagon ejwayelekile (enezinhlangothi eziyisithupha) Ukuhlelwa Kwentambo Intambo ye-metric coarse (ejwayelekile); intambo emincane iyatholakala Isiqondiso Sentambo Kwesokudla (kwesobunxele kuyatholakala ngokucela) Izinga Lomkhiqizo A (D ≤ 16 mm) / B (D > 16 mm) Izinga GB/T 6170-2015 (ukwamukelwa okuguquliwe kwe-ISO 4032:2012) Amantambo e-hexagon Uhlobo 1 ayisimo samantambo esiyisisekelo futhi esisetshenziswa kakhulu, enikeza ukuhlangana kwesikrufu sezinhlangothi eziyisithupha ukuze kudluliswe i-torque ethembekile kanye nokuhlangana okugcwele kwentambo nebhawodi elihambisanayo. Isimo se-hexagon sivumela ukuqinisa kusuka kunoma yiziphi izindawo eziyisithupha, okwenza la mantambo afanele ukuhlanganiswa kwesandla kanye nokuhlanganiswa okuzenzakalelayo. Izinto Zokwakha & Amazinga Amandla Izinga Izinto Umbukiso Womthwalo (MPa) Ubulukhuni Izinhlelo Ezijwayelekile 8 Insimbi ye-carbon emaphakathi (45#, 10B21), icushiwe futhi yathambiswa ≥ 800 MPa 250–320 HV Izakhiwo zensimbi, imishini, ukuxhumana okujwayelekile 10 Insimbi ye-carbon emaphakathi / insimbi ye-alloy, icushiwe futhi yathambiswa ≥ 1,040 MPa 320–380 HV Imishini esindayo, insimbi yesakhiwo, ukuxhumana okunomthwalo ophezulu 12 Insimbi ye-alloy (42CrMo, SCM435), icushiwe futhi yathambiswa ≥ 1,220 MPa 385–435 HV Izakhiwo ezibalulekile ezinengcindezi ephezulu, ukuxhumana kwamabhuloho Amantambo e-hexagon e-Grade 8 anikeza umthwalo wokubonisa omncane we-800 MPa futhi ayisinqumo esijwayelekile sezinhlelo ezijwayelekile zesakhiwo nemishini. I-Grade 10 inikeza cishe u-30% womthwalo wokubonisa ophezulu futhi icaciswa ekuxhumaneni okunomthwalo osindayo. I-Grade 12 ifinyelela umthwalo wokubonisa omncane we-1,220 MPa, ohambisana namandla okudonsa e-Grade 12.9 amabhawodi ezinhlelo ezinomthwalo ophezulu kakhulu. Umthetho obalulekile wokuhlangana: Amantambo kufanele ahlangane namabhawodi ezigaba zepropathi ezihambisanayo noma eziphezulu. Intambo ye-Grade 8 ifanele amabhawodi e-Grade 8.8; intambo ye-Grade 10 yamabhawodi e-Grade 10.9; intambo ye-Grade 12 yamabhawodi e-Grade 12.9. Ukusebenzisa intambo yekilasi eliphansi nebhawodi lekilasi eliphezulu kuzoholela ekukhumuleni kwentambo yentambo ngaphambi kokuba ibhawodi lifinyelele umthamo walo ogcwele womthwalo.
