Zizindikiro Pa Zomangira: Zikutanthauza Chiyani?

Zamkatimu

Zolemba Zamitu Zopanga

Zomangira zonse zimabwera ndi zolembera pamitu pawo zomwe zimathandiza kuzindikira chiyambi, zinthu, ndi kukula kwake. Opanga Fasteners ali ndi udindo wowonetsetsa kuti zinthu zawo zikudziwika bwino kwa makasitomala. Bukhuli limapereka chidziwitso chothandiza kukuthandizani kumvetsetsa ndikutanthauzira zolemba zomwe zili pa zomangira.

Zolemba Zamitu Zopanga

Chomangira chilichonse chopangidwa ndi kampani chimafunika kukhala ndi chizindikiritso chapadera pamutu pake. Izi zitha kukhala ndi zilembo kapena dzina lakampani. Mchitidwewu udalamulidwa ndi a Faster Quality Act kuti akhazikitse chidaliro kwa ogula omwe akugula kuchokera kwa wopanga wodalirika.

Miyezo ya Fastener

Kugwirizana kwapadziko lonse pakati pamakampani kwapangitsa kuti pakhale zilembo zofananira zomangira. Miyezo iyi imakhudza kapangidwe kazinthu, miyeso, kulolerana kwamitundu, ndi zokutira, zomwe zimapereka chidziwitso chokwanira pa chomangira chilichonse.

American Society for Mechanical Engineers (ASME) imapereka chikalata cha ASME B1.1, chomwe chimafotokoza zofunikira za ulusi wolumikizana wa inchi. ASME imatengedwa ngati muyezo ndi makampani ambiri.

Miyezo ina imatanthawuza magiredi a fastener kutengera zakuthupi ndi zakuthupi. Mwachitsanzo, SAE J429 imatanthauzira zofunikira pazitsulo za Giredi 2, Grade 5, ndi Giredi 8. Kudziwa kalasi ya fasteners kumapereka chidziwitso cha zinthu zake, kuuma kwake, mawonekedwe a electromechanical, komanso ngati amatsatira inchi kapena metric standard.

Zitsanzo za SAE J429 Grade 2, Grade 5 ndi Giredi 8

The Society of Automotive Engineers (SAE) yakhazikitsa mulingo wa SAE J429 wa Zofunikira Zamakina ndi Zinthu Zomangirira Ma Mechanical Fasteners. Mulingo uwu umalamula zida zamakina ndi zakuthupi zamabawuti inchi, zomangira,zolembasems, ndiU-bolts, kuphimba miyeso mpaka 1-½” m'mimba mwake. Kuwonjezeka kwa giredi ya chomangira kumawonetsa kulimba kwamphamvu kwambiri, komwe nthawi zambiri kumadziwika ndi mizere yozungulira mutu wa chomangira.

Dziwani kuti Grade 2 ya SAE J429 ikhoza kukhala yopanda zilembo. Komanso, zolembera za opanga zitha kusinthidwa pamutu wa chomangira kuti zigwirizane ndi mawonekedwe ake.
