Qhov muag tsis pom kev rivets feem ntau siv hauv kev lag luam xws li khaub ncaws thiab khau. Hollow rivets yog machined los ntawm lub hollow mus rau lub taub hau ntawm lub hauv paus ntawm semi hollow rivets. Vim lawv lub teeb yuag thiab cov ntsia hlau tsis muaj zog, lawv tau siv rau riveting ntawm cov ntaub ntawv uas tsis yog xim hlau nrog tsawg load.
Hollow rivets feem ntau yog siv hauv kev lag luam xws li khaub ncaws thiab khau,qhov twg cov khoom yuav tsum tau rov riveted thiab siv rau txuas hnyav workpieces. Lawv feem ntau yog cov qauv uas tsis tuaj yeem tshem tau, thiab cov rivets semi hollow feem ntau yog siv. Cov khi kawg (nrog rau lub taub me me) cov ntsia hlau yog ua los ntawm cov hlau tawv thiab tuaj yeem nkag mus rau cov hlau phaj hauv qhov tuab ntawm 0.5 hli yam tsis tas yuav tsum muaj qhov ua ntej.
Rivets tsis tuaj yeem khoov lossis deformed, thiab tau siv dav hauv cov ntawv lo lus zais, lub thawv mus ncig, thiab cov hnab tub rog, Hollow rivets (semi hollow rivets) yog tsim los siv cov xaim hloov tau yooj yim thiab feem ntau xav kom lawv tsis tuaj yeem tawg tom qab raug riveted. Muaj ntau ntau hom rivets, thiab tam sim no qee cov khoom ua si tau pib siv cov ntsia hlau semi hollow lossis cov menyuam thiab niam cov ntsia hlau los hloov cov shafts ntawm cov nplai loj, uas tuaj yeem txo cov nqi tsim khoom. Cov tub ntxhais rub tawm thiab cov tub ntxhais ntaus rivets feem ntau yog siv rau riveting nyias thiab mos cov ntaub ntawv, nrog rau feem ntau nruj me ntsis. Cov ntaub ntawv tsim khoom feem ntau yog tsim los ntawm cov khoom siv nrog cov yas zoo dua.
Cov rivets ntxov tshaj plaws yog cov ntsia hlau me me ua los ntawm cov ntoo lossis cov pob txha, thiab cov hlau deformation ntxov tshaj plaws yuav yog cov poj koob yawm txwv ntawm cov rivets peb paub niaj hnub no. Undoubtedly, lawv yog cov hiob paub txoj kev ntawm hlau kev twb kev txuas los ntawm tib neeg, yos rov qab mus txog rau thaum pib siv cov malleable hlau. Piv txwv li, thaum lub sij hawm Bronze Age, cov neeg Iyiv tau siv rivets los txuas rau 6 tus kiv cua ntoo ntawm cov kab sab nrauv ntawm cov log sib dhos ua ke. Tom qab cov neeg Greek tau ua tiav cov mlom loj hauv cov tooj liab, lawv siv cov rivets rau rivet ntau yam ua ke.
Hollow rivets feem ntau yog tsim los rau kev tsim khoom lossis kho cov khoom siv hlua. Nws tsis yog qhov tseeb heev thaum hollow rivets tau tsim, tab sis cov hlua khi tau tsim nyob nruab nrab ntawm 9th lossis 10th caug xyoo AD. Riveted harnesses, zoo li hooves nrog rau tes, liberated qhev los ntawm hnyav zog. Rivets kuj tau coj mus rau ntau qhov kev tsim khoom tseem ceeb, xws li cov hlau pliers siv los ntawm cov neeg ua haujlwm tooj liab thiab hlau thiab yaj cov txiab txiab.
Xyoo 1916, thaum HV Dawb ntawm lub tuam txhab British aircraft tsim thawj zaug tau txais patent rau qhov muag tsis pom rivets uas tuaj yeem riveted rau ntawm ib sab, tib neeg tsis tshua xav tias cov rivets yuav siv dav heev niaj hnub no. Los ntawm aerospace mus rau lub chaw ua hauj lwm cov cav tov, cov khoom siv hluav taws xob, thiab cov khoom siv ua kis las, nws tuaj yeem hais tias qhov muag tsis pom kev rivet tau dhau los ua txoj kev sib txuas zoo thiab ruaj khov.
