Fasteners Basics - Mbiri ya zomangira

Tanthauzo la chomangira: Fastener imatanthawuza nthawi yanthawi zonse ya zida zamakina zomwe zimagwiritsidwa ntchito pomwe magawo awiri kapena kuposerapo (kapena zigawo) alumikizidwa mwamphamvu muthunthu.Ndi gulu lomwe limagwiritsidwa ntchito kwambiri pamakina, kukhazikika kwake, kusanja, kuchuluka kwa chilengedwe chonse ndikwambiri, chifukwa chake, anthu ena ali ndi mulingo wapadziko lonse wagulu la zomangira zomwe zimatchedwa standard fasteners, kapena zimatchedwa magawo okhazikika.Screw ndilo liwu lodziwika kwambiri la zomangira, zomwe zimatchedwa kuti mawu apakamwa.

Pali mitundu iwiri ya mbiri ya fasteners padziko lapansi.Imodzi ndi Archimedes '"Archimedes spiral" yonyamula madzi kuyambira zaka za zana lachitatu BC.Akuti ndiye chiyambi cha wononga, chomwe chimagwiritsidwa ntchito kwambiri pa ulimi wothirira m'munda.Egypt ndi maiko ena aku Mediterranean amagwiritsabe ntchito mtundu uwu wa conveyor wamadzi, chifukwa chake, Archimedes amatchedwa "bambo wa screw".

Mtundu winanso ndi mawonekedwe a mortise ndi tenon kuyambira nthawi ya New Century ku China zaka zoposa 7,000 zapitazo.The mortise ndi tenon kapangidwe ndi crystallization wa nzeru zakale Chinese.Zigawo zambiri zamatabwa zomwe zidafukulidwa pamalo a Hemudu People ndizomwe zimayikidwa ndi ma convex awiri.Misomali yamkuwa idagwiritsidwanso ntchito m'manda a Central Plains munthawi ya Yin ndi Shang Dynasties ndi Nyengo za Spring ndi Autumn ndi Warring States.Mu Iron Age, Mzera wa Han, zaka zoposa 2,000 zapitazo, misomali yachitsulo inayamba kuonekera ndi chitukuko cha njira zakale zosungunulira.

Zomangamanga zaku China zili ndi mbiri yakale.Kuchokera kumapeto kwa zaka za m'ma 1800 mpaka kumayambiriro kwa zaka za m'ma 1900, ndi kutsegulidwa kwa madoko a mgwirizano wa m'mphepete mwa nyanja, zomangira zatsopano monga misomali yakunja kuchokera kunja zinabwera ku China, kubweretsa chitukuko chatsopano kwa zomangira za ku China.

Kumayambiriro kwa zaka za m'ma 1900, shopu yoyamba yachitsulo ku China yopanga zomangira idakhazikitsidwa ku Shanghai.Pa nthawiyo, ankalamulidwa kwambiri ndi timagulu tating'onoting'ono ndi mafakitale.Mu 1905, kulowetsedwa kwa Shanghai Screw Factory unakhazikitsidwa.

Pambuyo pa kukhazikitsidwa kwa People's Republic of China, kukula kwa fasteners kunapitilira kukula, ndipo kunafika posinthira mu 1953, pomwe Unduna wa Zamagetsi Zaboma udakhazikitsa fakitale yapadera yopanga zomangira zomangira, ndipo kupanga cholumikizira kunaphatikizidwa mu dziko. dongosolo.

Mu 1958, gulu loyamba la miyezo yolumikizira idatulutsidwa.

Mu 1982, Standardization Administration inapanga zinthu za 284 zomwe zimatchulidwa, zinali zofanana kapena zofanana ndi zapadziko lonse, ndipo kupanga zomangira ku China kunayamba kugwirizana ndi mayiko.

Ndi chitukuko chofulumira chamakampani opanga ma fasteners, China yakhala dziko loyamba kupanga zomangira.
