Kodi Rivet Yowonjezera Yachizolowezi ya Aluminium-Steel ndi Chiyani?

1. Kodi Rivet Yowonjezera Ya Aluminium-Steel Rivet ndi chiyani kwenikweni?

Chitsulo Chowonjezera cha Aluminium-Iron Rivet ndi chinthu chapadera chomangirira chomwe chimapangidwira kulumikiza zida zogwirira ntchito zokhuthala kapena zambiri. Chili ndi thupi lotambasuka la rivet (lokhala ndi kutalika kuyambira 10mm mpaka 70mm, losinthika) ndipo chimagwiritsa ntchito kapangidwe ka aluminiyamu (thupi la rivet) ndi chitsulo champhamvu kwambiri (mandrel). Mosiyana ndi ma rivet wamba omwe ndi oyenera zida zogwirira ntchito zoonda zokha, kapangidwe kake kotambasuka kamalola kulumikizana kokhazikika kwa zida zogwirira ntchito zokhala ndi makulidwe onse a 5mm mpaka 45mm. Chimatsatira mfundo yoyambira yogwirira ntchito ya ma rivet osawona: mfuti ya rivet ikakoka mandrel yachitsulo, thupi la rivet la aluminiyamu limakula ndikumangirira zida zogwirira ntchito mwamphamvu, zomwe zimapangitsa kulumikizana kolimba komanso kolimba.

2. Kodi ubwino wake waukulu ndi wotani poyerekeza ndi ma rivets wamba ndi zomangira zina zotalikirapo?

Zimaonekera bwino m'mbali zitatu zofunika:

·Kapangidwe Kowonjezera Koyenera ka Ntchito Zokhuthala: Thupi la riveti yotambasuka limayang'ana mwachindunji malo opweteka omwe ma riveti wamba "sangafikire" kapena "kulumikizana mosakhazikika" m'malo okhuthala ogwirira ntchito. Mwachitsanzo, polumikizana ndi mbale zachitsulo zokhuthala 30mm ndi ma profiles a aluminiyamu, imatha kulowa bwino ndikupanga malo okwanira omangirira, pomwe ma riveti wamba a mulifupi womwewo adzalephera chifukwa cha kutalika kosakwanira.

·Chopangidwa ndi Aluminiyamu ndi Chitsulo Chopangira Magwiridwe Abwino: Thupi la rivet la aluminiyamu lili ndi ubwino wolemera pang'ono, kukana dzimbiri bwino, komanso kugwirizana bwino ndi aluminiyamu, mkuwa, ndi zida zina zachitsulo zopanda chitsulo; mandrel yachitsulo yamphamvu kwambiri imapereka mphamvu yokwanira yokoka (mphamvu yokoka mpaka 280MPa), kuonetsetsa kuti thupi la rivet silikuwonongeka kapena kusweka panthawi yoyika. Poyerekeza ndi rivet zotambasulidwa ndi chitsulo chonse, imachepetsa kulemera ndi 35% ndipo imapewa dzimbiri la galvanic ndi zida zopanda chitsulo; poyerekeza ndi rivet zotambasulidwa ndi aluminium zonse, mphamvu yake yocheka imawonjezeka ndi 40%.

·Yotsika Mtengo Komanso Yosavuta Kutchuka: Monga chinthu "chachizolowezi", chimasiya mapangidwe ovuta kwambiri a kapangidwe kake (monga nyumba zitatu kapena zomangira zambiri) pamene chikutsimikizira kuti chikugwira ntchito bwino, kuchepetsa ndalama zopangira. Mtengo wake ndi 15%-20% yokha kuposa wa ma rivets wamba, womwe ndi wotsika kwambiri kuposa wa ma fasteners apadera otambasulidwa apamwamba. Nthawi yomweyo, imagwirizana ndi mfuti wamba zamanja kapena zapneumatic rivets, ndipo palibe zida zina zapadera zomwe zimafunikira kuti ziyikidwe, zomwe zimachepetsa kwambiri malire ogwiritsira ntchito.
