Mphamvu Yapamwamba ya Hexagon Head Bolt Electric Fastener

Maboti amphamvu kwambiri a hexagon, omwe amapangidwa ndi chitsulo champhamvu kwambiri kapena amafunikira kuyika patsogolo kwambiri, amatha kutchedwa ma bolts amphamvu kwambiri. Maboti amphamvu kwambiri amagwiritsidwa ntchito kwambiri polumikiza milatho, njanji, zida zothamanga kwambiri komanso zida zapamwamba kwambiri. Kuthyoka kwa mtundu uwu wa bolt ndi brittle fracture. Mabawuti amphamvu kwambiri omwe amayikidwa pazida zothamanga kwambiri amafunika kusinikizidwa kuti atsimikizire kusindikizidwa kwa chidebecho. Masiku ano, zopanga zapamwamba zoyimiridwa ndi ndege zazikulu, zida zazikulu zopangira magetsi, magalimoto, masitima othamanga kwambiri, zombo zazikulu ndi zida zazikulu zonse zidzalowa munjira yofunika kwambiri yachitukuko. Chifukwa chake, zomangira zidzalowa gawo lofunikira lachitukuko. Maboti amphamvu kwambiri amagwiritsidwa ntchito polumikiza makina ofunikira. Ma disassembly obwerezabwereza kapena njira zingapo zoyika torque zimakhala ndi zofunika kwambiri pamaboti amphamvu kwambiri. Choncho, ubwino wa mawonekedwe ake apamwamba ndi kulondola kwa ulusi zidzakhudza mwachindunji moyo wautumiki ndi chitetezo cha wolandirayo. Pofuna kukonza kugundana kwamphamvu komanso kupewa dzimbiri, kugwidwa kapena kupindika mukamagwiritsa ntchito, zofunikira zaukadaulo zimanena kuti pamwamba pake payenera kupakidwa nickel phosphorous plating. Makulidwe a zokutira ayenera kukhala mkati mwa 0.02 ~ 0.03mm, ndipo zokutira zizikhala zofanana, zowundana komanso zopanda mapini.

Bolt zakuthupi: 18Cr2Ni4W, 25Cr2MoV zitsulo; Ndondomeko ya bolt: M27 ~ M48. Chifukwa chitsulo chamtundu uwu n'chosavuta kupanga filimu yongokhala pamwamba, ndipo filimuyi imapangitsa kuti bawutiyo isathe kupeza wosanjikiza wa nickel phosphorous ndi kumamatira bwino, njira zapadera zodzitetezera ziyenera kuchitidwa kuti muchotse filimuyo poyamba, ndi miyeso. ziyenera kutengedwa kuti zipewe kusinthika kwake, kuti zitsimikizidwe kuti zimamatira bwino pakati pa zokutira zomatira ndi gawo lapansi. Panthawi imodzimodziyo, kukula kwakukulu kwa geometric kwa bawuti kumawonjezera kuvutika kwa nickel phosphorous plating chithandizo ndi kuzindikira kwabwino munjirayo. Mayendedwe a nickel phosphorous plating kwa mabawuti amphamvu amakhala ndi magawo atatu:

Gawo loyamba ndi ndondomeko yokonzekera, kuphatikizapo kuyang'anitsitsa mwatsatanetsatane ndi maonekedwe asanayambe kuyikapo, kuchotsa mafuta pamanja, kuthira mafuta, pickling, electroactivation ndi flash nickel plating ya ma bolts amphamvu kwambiri;

Gawo II electroless nickel plating ndondomeko;

Gawo lachitatu ndi njira yopangira chithandizo pambuyo pake, kuphatikiza kutentha kwa hydrogen pagalimoto, kupukuta ndi kuwunika komaliza. Motere:

Kuwunika kwa mankhwala a mabawuti → kuyang'ana molondola ndi maonekedwe a mabawuti musanawaike → kupukuta pamanja → kuyang'ana mawonekedwe → kumiza kumiza → kusambitsa madzi otentha → kutsuka madzi ozizira → pickling ya asidi → kuchapa madzi ozizira → kutsegula kwa electro → kusamba madzi ozizira → kupukuta faifi tambala kutsuka madzi ozizira → kutsuka madzi osakaniza → kuyika faifi tating'ono → kutsuka m'madzi osakaniza → kutsuka m'madzi ozizira → hydrogen drive → kupukuta → kuyang'ana kwazinthu zomalizidwa.
