Cov rivets ntawm keeb kwm yog cov studs me me ua los ntawm ntoo lossis cov khoom mos, thiab lub cev hlau yuav yog tus poj koob yawm txwv ntawm rivet uas peb paub niaj hnub no.
Tsis muaj qhov tsis ntseeg tias lawv yog txoj kev ntawm kev sib txuas hlau paub, hnub rov qab mus rau kev siv hlau malleable kom deb li deb, piv txwv li: Lub Caij Nyoog Tooj Liab cov neeg Iyiv tau riveted rau lub cev ntoo kiv cua sab nraum lub log slotted nrog rivets, thiab cov neeg Greek tau ua tiav casting cov duab puab loj nrog bronze, thiab tom qab ntawd riveted cov khoom ua ke. 1916, thaum lub tuam txhab tsim dav hlau Askiv H. Thaum V White tau txais lub rivet dig muag patented uas tuaj yeem riveted rau ntawm ib sab, nws tsis yog xav tias lub rivet yuav siv dav dav niaj hnub no.
Txij li ntawm aerospace mus rau cov tshuab hauv chaw ua haujlwm, cov khoom siv hluav taws xob thiab cov khoom siv ua si, qhov rivet dig muag no tam sim no tau dhau los ua txoj hauv kev sib txuas khoom siv zoo thiab muaj zog. Hollow rivets feem ntau yog tsim los rau kev tsim khoom lossis kev saib xyuas cov cuab yeej nees, thiab thaum lub hollow rivet tau tsim, nws tsis meej heev, tab sis cov khoom siv tau tsim nyob rau hauv lub xyoo pua 9th lossis 10th.
Tus nees riveting, zoo li lub khau nees nrog cov ntsia hlau, tau tso cov qhev tawm ntawm kev ua haujlwm hnyav, thiab lub rivet kuj tau ua rau muaj ntau yam kev tsim kho tshiab tseem ceeb, xws li cov hlau pliers rau cov neeg ua haujlwm tooj liab thiab hlau thiab cov plaub yaj thiab txiab. Feem ntau siv yog R-hom rivets, kiv cua rivets, core rivets (core rivets), ntoo rivets, semi-circular taub hau, tiaj tus, semi-hollow rivets, khoom rivets, countersunk taub hau rivets, core rivets, hollow rivets, uas feem ntau yog siv los txuas cov khoom riveted nrog lawv tus kheej deformation. Feem ntau tsawg dua 8 hli nrog riveting txias, loj dua qhov loj ntawm kev siv thermal riveting. Txawm li cas los xij, muaj qee qhov kev zam, xws li lub npe ntawm qee lub xauv, uas yog riveted los ntawm kev cuam tshuam ntawm rivet thiab lub qhov xauv lub cev.
