Uhlolojikelele Lomkhiqizo Lo mkhiqizo uyisikulufu esinamandla aphezulu esinekhanda eliyisilinda esine-hex socket (esaziwa nangokuthi isikulufu sekhanda le-socket, ibhawodi lika-Allen, noma isikulufu sekhanda lenkomishi), esakhiwe ngensimbi ye-alloy yekhwalithi ephezulu ku-Property Class 12.9 ngokwe-ISO 898-1 — izinga lamandla eliphezulu kakhulu elijwayelekile lezinto zokubopha ze-metric. Inekhanda eliyisilinda eline-hexagonal socket drive kanye ne-zinc-plated (blue-white) finish yokuvikela ukugqwala. Isikulufu sihambisana nezindinganiso ze-DIN 912 / ISO 4762 futhi sitholakala ngosayizi womucu kusuka ku-M3 kuya ku-M36 (M42–M64 ngesicelo). Isigaba se-12.9 sikhombisa amandla okudonsa okungenani angu-1,220 MPa (177,000 psi) kanye namandla okukhiqiza angu-1,100 MPa (160,000 psi) — okwenza lezi zikulufu zifanele izinhlelo ezidinga kakhulu zamandla aphezulu emishinini, ezimoto, ezindizeni, kanye nobunjiniyela besakhiwo. I-hexagonal socket drive ivumela ukudluliswa kwe-torque ephezulu kune-external hex noma i-Phillips drive, ivumela amaphrofayili ekhanda ahlangene ezinhlelweni ezifihliwe, futhi inikeza ukuqondanisa okunembile ngesikhathi sokufaka. Izinto Zokwakha Namazinga Amandla Izinga Into Amandla Okudonsa (okungenani) Amandla Okukhiqiza (okungenani) Ubulukhuni Izicelo Ezijwayelekile 8.8 Insimbi ye-carbon emaphakathi (45#, 10B21) ≥800 MPa ≥640 MPa 250–320 HB Imishini ejwayelekile, yesakhiwo 10.9 Insimbi ye-alloy (35CrMo, 40Cr, SCM435) ≥1,040 MPa ≥940 MPa 320–380 HV Imishini esindayo, ezimoto 12.9 Insimbi ye-alloy (42CrMo, SCM435) ≥1,220 MPa ≥1,100 MPa 385–435 HV Izicelo ezibalulekile zamandla aphezulu Amabhawodi e-Grade 12.9 enziwa nge-alloy steel eqinisiwe futhi elungisiwe (ngokuvamile i-42CrMo noma i-SCM435) futhi afinyelela amandla okudonsa okungenani angu-1,220 MPa ngobulukhuni obungu-38–44 HRC (cishe 385–435 HV). Isibonakaliso esithi "12.9" sikhombisa ukuthi amandla okudonsa okungenani acishe abe ngu-1,220 MPa (12 × 100 = 1,200 MPa okushiwo) futhi isilinganiso se-yield-to-tensile singu-0.9 (1,220 × 0.9 ≈ 1,100 MPa). I-Grade 12.9 inikeza cishe amandla okudonsa aphezulu ngo-50% kune-Grade 8.8 kanye no-17% aphezulu kune-Grade 10.9, okwenza kube ukukhetha okuthandwayo ezinhlelweni ezibalulekile ezinengcindezi ephezulu lapho kudingeka khona umthamo ophezulu womthwalo. Ukwakheka kwezinto ngokuvamile kufaka i-0.37–0.41% carbon, i-0.90–1.20% chromium, kanye ne-0.15–0.30% molybdenum ukuze kukwazi ukuqiniswa ngokugcwele. Izindinganiso Nezicaciso Ipharamitha Imininingwane Uhlobo Lomkhiqizo Isikulufu Sekhanda Le-Hex Socket (Ikhanda Elilindile) Indinganiso DIN 912 / ISO 4762 / BS 4168 / UNI 5931 / JIS B 1176 Usayizi Womucu M3, M4, M5, M6, M8, M10, M12, M16, M20, M24, M30, M36 (M42–M64 ngesicelo) I-Thread Pitch M3×0.5, M4×0.7, M5×0.8, M6×1.0, M8×1.25, M10×1.5, M12×1.75, M16×2.0, M20×2.5, M24×3.0 Ububanzi Bobude 6 mm – 300 mm (kungenziwa ngokwezifiso) Ukubekezelelana Komucu 6g (metric) Into Insimbi ye-alloy: 42CrMo / SCM435 / 35CrMo Ukuqedwa Kwendawo Zinc Plated (Blue-White / Clear / Yellow) Uhlobo Lwe-Drive I-Hexagonal socket (Allen key) Izinga Lomkhiqizo A (ngokwe-ISO 4762) I-DIN 912 iyindinganiso yakudala yaseJalimane yezikulufu zekhanda le-hex socket, ehlanganisa imicu ye-metric coarse kusuka ku-M1.6 kuya ku-M64 ku-product grade A. I-ISO 4762 iyilingana nomhlaba wonke futhi ithathe indawo ye-DIN 912 njengendinganiso eyinhloko. Izikulufu ze-DIN 912 ne-ISO 4762 ziyashintshana — zabelana ngobukhulu obufanayo nezici, kanti i-ISO 4762 ifaka ukubekezelelana okubuyekeziwe kosayizi we-wrench kanye nokwengezwa kwamazinga e-stainless steel A3–A5. I-BS 4168 (I-British Standard) ne-UNI 5931 (I-Italian Standard) ziyizilinganiso zikazwelonke ezihambisana ngobukhulu ne-DIN 912 / ISO 4762. I-JIS B 1176 iyilingana neyaseJapane.

Ubulukhuni be-Rockwell C ngokuvamile busukela ku-39 kuya ku-44 HRC. Izinga lokushisa eliphezulu lokusebenza lezikulufu ze-Grade 12.9 ezingafakwanga i-plating lingu-300°C; izinguqulo ezine-zinc-plated zinezinga lokushisa eliphezulu lokusebenza cishe elingu-150–200°C kuye ngohlelo lokumboza. I-Zinc Plating Nokuvikelwa Kokugqwala Ukuqedwa Ukujiya Kokumboza Ukumelana Ne-Salt Spray Indawo Enconywayo Zinc Plated (Blue-White) 8–12 μm 72–144 amahora Ngaphakathi, imboni ejwayelekile Zinc Plated (Yellow) 8–12 μm 96–168 amahora Ngaphandle, ukugqwala okuphakathi Zinc Plated (Clear) 5–8 μm 48–96 amahora Ngaphakathi, ukuvikelwa kwesikhashana Zinc-Nickel Plated 8–12 μm 500–1,000+ amahora Ogwini, ezimoto, ukugqwala okuphezulu Dacromet (Isithenjwa) 5–12 μm 600–1,500+ amahora Ogwini, olwandle, ukugqwala okuphezulu I-zinc plating inikeza ukuvikelwa kwe-sacrificial (cathodic) ensimbi ye-alloy engaphansi. Ukumboza kwe-zinc kugqwala kuqala, kuvikela i-substrate yensimbi ekugqwaleni. I-blue-white zinc plating ejwayelekile inikeza ukuvikelwa okuhle kokugqwala ezindaweni zangaphakathi nezimboni ezijwayelekile. Iphuzu elibalulekile mayelana nokugqwala kwe-hydrogen: Ngenxa yobulukhuni bazo obuphezulu (≥320 HV), izikulufu ze-Grade 12.9 zisengozini yokugqwala kwe-hydrogen lapho zifakwa i-electroplating. Ngokwe-ISO 4042, izinto zokubopha ezinobulukhuni obungaphezu kwe-320 HV zidinga ukubhakwa ngemuva kokumboza ku-190–220°C amahora angu-4–24 ukuze kukhululwe i-hydrogen. Ezinhlelweni ezibalulekile ezindaweni zasogwini noma olwandle, i-Dacromet noma i-zinc-flake coatings inconywa njengezinye izindlela eziqeda ngokuphelele ingozi yokugqwala kwe-hydrogen.

Ezintweni zokubopha ezigcotshiwe noma ezimboziwe, lungisa i-torque ngokufanele. Izicelo Izikulufu zekhanda le-socket ze-Grade 12.9 zisetshenziswa kakhulu ezinhlelweni ezidinga amandla aphezulu, ukuqiniswa okunembile, namaphrofayili ekhanda ahlangene: Ukuhlanganiswa Kwemishini Namathuluzi — Ukufakwa kwe-spindle, ukuqiniswa kwe-tool holder, ukuhlanganiswa kwe-fixture Ezimoto Ne-Powertrain — Izingxenye zenjini, izindlu ze-transmission, ukuxhumana kwe-chassis Ezindizeni Nezokuvikela — Ukubopha kwesakhiwo se-airframe, izintaba zenjini, ama-bracket e-avionics Imishini Yezimboni — Ama-press, imishini ye-CNC, imishini yokubumba, izinhlelo ze-hydraulic Ukwenza Isikhunta Ne-Die — Ukuhlanganiswa kwesisekelo sesikhunta, ukuqiniswa kwe-ejector plate, ukuqiniswa kwe-die Ama-Robotics Ne-Automation — Amalunga engalo ye-robot, imihlahlandlela yokunyakaza eqondile, ukufakwa kwe-end effector Amandla Nokukhiqizwa Kukagesi — Izingxenye ze-turbine, ukufakwa kwe-generator, ukuhlanganiswa kwe-switchgear Imishini Yezokwelapha Nenembile — Amathuluzi okuhlinza, imishini yokuxilonga, izintaba ze-optical Ibhayisekili Nesithuthuthu — Amabhawodi e-stem, ama-brake calipers, ukufakwa kwe-disc rotor Umjaho Nokusebenza — Izingxenye ze-suspension, izintaba zenjini, ukuqiniswa kwe-chassis Ikhanda elilindile elihlangene livumela ukuthi isikulufu sisetshenziswe emigodini efihliwe noma ene-counterbore lapho ikhanda le-external hex lalingeke lingene. I-hex socket drive ivumela ukudluliswa kwe-torque ephezulu ngosayizi omncane we-wrench, okwenza lezi zikulufu zifanele izindawo eziqinile nokuhlanganiswa okunembile. Ukupakisha Nokwenza Ngokwezifiso Ukupakisha Kokuthumela Ngaphandle: Ikhathoni / ibhokisi lokhuni / i-steel pallet Ukupakisha Kwasekhaya: Ibhokisi le-corrugated elijwayelekile / isikhwama I-OEM/ODM: Iyatholakala — osayizi abenziwe ngokwezifiso, izinhlobo zomucu, izinto, amazinga amandla, nokuqedwa kwendawo kungenziwa ngokwemidwebo noma amasampula I-MOQ: Kuyaxoxisana Ukuqinisekiswa Kwekhwalithi Yonke imikhiqizo yenziwa ngaphansi kwezinqubo zokulawula ikhwalithi eziqinile ngokuhambisana ne-ISO 898-1 (izici zemishini zezinto zokubopha), i-ISO 4762 / DIN 912, ne-ISO 4042 (ama-electroplated coatings). Umkhiqizo uzuze izinga lokubuyekezwa okuhle lika-100% ngezinga lokuthenga kabusha lika-50% kunkundla, okubonisa ikhwalithi engaguquki nokwaneliseka kwamakhasimende. Izitifiketi zokuhlolwa kwezinto (EN 10204 3.1), imibiko yokuhlolwa kobukhulu, imibiko yokuhlolwa kobulukhuni, kanye nemibiko yokuhlolwa yabantu besithathu (SGS, BV, CTI) kunganikezwa ngesicelo. Ezikulufini ze-Grade 12.9, ukuhlolwa kokudonsa, ukuhlolwa kobulukhuni, kanye nokuqinisekiswa kokukhululwa kokugqwala kwe-hydrogen kwenziwa ku-batch ngayinye yokukhiqiza. Imininingwane Yokuthenga Ukuze ufake i-oda noma ucele isilinganiso, sicela ucacise: Uhlobo lomkhiqizo — Isikulufu sekhanda le-hex socket (DIN 912 / ISO 4762) Indinganiso — DIN 912 / ISO 4762 / BS 4168 / JIS B 1176 Into — Insimbi ye-alloy (42CrMo / SCM435 / 35CrMo) Izinga lamandla — 8.8 / 10.9 / 12.9 Usayizi womucu ne-pitch — isb., M8 × 1.25 noma M12 × 1.75 Ubude — Cacisa ubude obuphelele (isb., 20 mm, 30 mm, 50 mm) Ukuqedwa kwendawo — Zinc plated (cacisa umbala) / Zinc-nickel / Dacromet / Plain Inani — Ngokubekezelelana kokuthunyelwa okungaphezulu/okungaphansi Isitifiketi — EN 10204 3.1 MTC / Ukuhambisana ne-ISO 898-1 / SASO (yeSaudi Arabia) / GOST-K (yeKazakhstan) Izidingo ezikhethekile — Ukubekezelelana komucu, ukumaka, ukupakisha, umbiko wokuhlolwa kokugqwala kwe-hydrogen, njll.
