Amabhawodi ekhanda le-hex anamandla aphezulu e-Grade 8.8 ayizikhonkwane eziqinisiwe futhi zafakwa i-tempering ezakhiwe nge-medium carbon steel noma i-alloy steel, eziklanyelwe ukuxhuma kwezakhiwo nemishini edinga ukulingana kwamandla aphezulu okudonsa, ukumelana nokukhathala, kanye nokonga izindleko. Ngamandla okudonsa asezingeni eliphansi angu-800 MPa namandla okukhiqiza asezingeni eliphansi angu-640 MPa, lawa mabhawodi anikeza cishe ukuphindwe kabili komthwalo wamabhawodi ajwayelekile e-Grade 4.8, okuwenza abe yisinqumo esijwayelekile emishinini, ezimoto, nasekusetshenzisweni kobunjiniyela jikelele. I-black oxide surface finish inikeza ukubukeka okuhlanzekile, okugcina uwoyela okufanele izimakethe zasekhaya nezokuthumela ngaphandle. Itholakala nge-M8 ne-M10 njengesitokwe esilungile, kanti uhla oluphelele lusuka ku-M5 kuya ku-M39 ngesicelo. Izicaciso Ezibalulekile Ipharamitha Isicaciso Izinga Lamandla 8.8 Impahla Medium carbon steel / alloy steel (eqinisiwe futhi yafakwa i-tempering) Izinga GB/T 5783 / ISO 4017 / DIN 933 Intambo Metric coarse (M), intambo egcwele I-Surface Finish Black oxide Ububanzi Bentambo M5 – M39 (M8, M10 esitokweni) Ubude 10 mm – 200 mm (ubude obenziwe ngokwezifiso buyatholakala) Uhlobo Lwekhanda Ikhanda le-hexagon Izici Zemishini (ISO 898-1 / GB/T 3098.1) Isici M5 – M16 M18 – M39 Amandla Okudonsa Asezingeni Eliphansi (Rm) 800 MPa 830 MPa Amandla Okukhiqiza Asezingeni Eliphansi (Rp0.2) 640 MPa 660 MPa Ingcindezi Yokuhlola Umthwalo Asezingeni Eliphansi (Sp) 580 MPa 600 MPa Ubulukhuni Bengaphakathi 22–32 HRC 23–34 HRC Ukweluleka Ngemuva Kokuphuka (A min) 12% 12% Isimo Sempahla Siqinisiwe futhi safakwa i-tempering Siqinisiwe futhi safakwa i-tempering Lawa manani ahambisana nezidingo ze-ISO 898-1 zezinga lempahla 8.8. I-Grade 8.8 isho amandla okudonsa okulinganiselwe angu-800 MPa kanye nesilinganiso samandla okukhiqiza esingu-0.8 (ngakho-ke 8.8). U-“8” ongaphambi kwedesimali ukhombisa ingxenye eyodwa yeshumi yamandla okudonsa asezingeni eliphansi nge-MPa, kanti u-“8” ongemuva kwedesimali ukhombisa u-80% wamandla okudonsa njengamandla okukhiqiza asezingeni eliphansi. Impahla Nokwelashwa Ngokushisa Amabhawodi e-Grade 8.8 enziwe nge-medium carbon steel (njenge-35# noma i-45#) noma i-alloy steel (njenge-40Cr noma i-SCM435). Impahla idlula ekwelashweni ngokushisa — ukushisisa ezingeni lokushisa le-austenitizing, ukupholisa ngokushesha ukwakha i-martensite, kanye ne-tempering elawulwayo ukuze kuzuzwe inhlanganisela edingekayo yamandla, ukuguquguquka, nokuqina. Lokhu kwelashwa ngokushisa kwehlukanisa i-Grade 8.8 nezinga eliphansi futhi kubalulekile ukuze kuhlangatshezwane nezidingo zezici zemishini ze-ISO 898-1. Amazinga Nokuhambisana Lawa mabhawodi akhiqizwa ngokuhambisana ne-GB/T 5783 (izinga likazwelonke laseShayina lamabhawodi ekhanda le-hex anentambo egcwele, ehlanganisa i-M1.6–M64 kanye nezigaba zempahla ezihlanganisa u-8.8), futhi ngokobukhulu ayalingana ne-ISO 4017 ne-DIN 933. Ukumakwa kwezinga 8.8 kugxivizwa ekhanda lebhawodi ukuze kwaziwe futhi kulandeleke. Ukwelashwa Kwangaphezulu I-black oxide finish ejwayelekile inikeza ukuvikelwa okuncane ekugqwaleni kanye nokubukeka kwangaphezulu okuhlanzekile, okugcina uwoyela. I-black oxide ivamise ukusetshenziswa kumabhawodi aqinisiwe futhi afakwe i-tempering ukuze kube nokubukeka okufanayo, okungokomsebenzi. Ukuze kuthuthukiswe ukumelana nokugqwala, ezinye izindlela zokugcina ezinjenge-zinc plating, i-zinc-nickel coating, noma i-Dacromet ziyatholakala ngesicelo. Qaphela: Emabhawodini anamandla aphezulu afakwe nge-electroplating, ukubhaka kwe-dehydrogenation phakathi namahora angu-24 ngemuva kwe-plating kunconywa ukuvimbela ukuqhekeka kwe-hydrogen embrittlement. Ukusetshenziswa Amabhawodi e-hex e-Grade 8.8 ayisinqumo esijwayelekile ezinhlelweni ezidinga ukulingana kwamandla aphezulu nokonga izindleko: Ukuhlanganisa imishini nemishini Izisekelo ze-chassis nezimoto ze-injini Ukuxhumana kwensimbi yesakhiwo (okungafakwanga umthwalo wangaphambili) Ukuqinisa amaloli asindayo nama-trailer Imishini yezolimo neyokwakha Ukulungisa nokulungisa izitshalo zezimboni Osayizi Abatholakalayo Intambo (M) Ubude Obujwayelekile I-Hex Across-Flats (s) M8 16 – 80 mm 13 mm M10 20 – 100 mm 16 mm M12 25 – 120 mm 18 mm M16 30 – 150 mm 24 mm M20 40 – 200 mm 30 mm Uhla oluphelele lutholakala kusuka ku-M5 kuya ku-M39. I-M8 ne-M10 zigcinwa esitokweni esilungile ukuze zithunyelwe ngokushesha. Ubude obenziwe ngokwezifiso kanye nama-thread pitches ayatholakala ngesicelo. Imininingwane Yokuhlela Osayizi bentambo: M5–M39 okujwayelekile; M8, M10 esitokweni Ubude: 10–200 mm okujwayelekile; ubude obenziwe ngokwezifiso buyatholakala Izindlela zokugcina: Black oxide (okujwayelekile); zinc plated, zinc-nickel, Dacromet ngesicelo Ukupakisha: Ibhokisi elikhulu, ibhokisi elincane, noma ukupakisha okuthunyelwa ngaphandle okwenziwe ngokwezifiso Imibhalo: Izitifiketi zokuhlolwa kwemboni kanye nokulandeleka kwempahla kuyatholakala I-MOQ: Iguquguqukayo kuma-oda okuthengisa ngobuningi nabasabalalisi Sicela ubuze ngezinhlanganisela ezithile zosayizi, amanani entengo yomthamo, kanye nezikhathi zokuhola.
