Riveting yog txheej txheem uas siv lub tog raj kheej hlau lossis lub raj -paub tias yog lub rivet- nrog txoj kab uas hla me me dua li ntawm qhov ua ntej -drilled qhov nyob rau hauv lub workpieces mus koom. Lub rivet yog ntxig los ntawm cov khoom ua haujlwm, thiab nws ob qhov kawg yog ces ntaus los yog raug rau siab. Qhov kev txiav txim no ua rau cov hlau kem (los yog raj) kom deform thiab nthuav tawm radially thaum ib txhij ua "lub taub hau" (los yog cap) ntawm ob qho kawg, yog li tiv thaiv cov khoom ua haujlwm los ntawm kev tshem tawm ntawm rivet. Thaum raug rau sab nraud quab yuam uas sim cais cov workpieces, lub rivet shank thiab lub taub hau sib sau ua ke ua rau lub zog shear, zoo tiv thaiv cov workpieces los ntawm rub tawm.
Lub riveted sib koom ua ke yog ib hom uas tsis yog -dismountable, zoo li qub kev twb kev txuas- feem ntau tsuas yog hu ua "riveting"- uas ntiav rivets los koom ob los yog ntau yam khoom (feem ntau hlau phaj los yog cov qauv profiles) ua ke. Rivets feem ntau poob rau hauv ob pawg loj: hollow thiab khoom. Feem ntau siv daim ntawv riveting muaj cov khoom rivets. Cov pob qij txha rivet feem ntau yog siv rau kev sib txuas cov khoom siv hlau uas raug cov khoom hnyav, feem ntau cov hollow rivet pob qij txha feem ntau yog siv rau kev sib koom ua ke nyias daim hlau los yog tsis yog- cov khoom siv hlau raug hnyav dua.
Cov txheej txheem riveting tau dav faib ua ob hom: txias riveting thiab kub riveting. Kub riveting feem ntau ua rau kev sib koom ua ke nruj dua; Txawm li cas los xij, ib feeb tshem tawm tseem nyob nruab nrab ntawm lub rivet shank thiab lub qhov phab ntsa, txhais tau tias lub shank nws tus kheej tsis ncaj qha rau kev thauj mus los. Nyob rau hauv sib piv, thaum lub sij hawm txias riveting, lub rivet shank undergoes upsetting (radial expansion) kom puv lub qhov, yog li tshem tawm tej clearance ntawm lub shank thiab lub qhov phab ntsa. Hlau rivets nrog diameters tshaj 10 hli feem ntau yog cua sov rau qhov kub ntawm 1000℃thiab 1100℃rau kub riveting, nrog rau cov hammering quab yuam siv rau lub rivet shank nruab nrab ntawm 650 MPa thiab 800 MPa ib cheeb tsam. Hloov pauv, steel rivets nrog txoj kab uas hla hauv qab 10 hli- nrog rau cov rivets ua los ntawm cov hlau tsis muaj -ferrous hlau, lub teeb hlau, thiab cov alloys uas muaj qhov siab ductility{12}} feem ntau yog koom nrog txoj kev txias riveting.
Cov yam ntxwv tseem ceeb ntawm riveting muaj xws li txheej txheem simplicity, kev sib txuas kev ntseeg tau, thiab zoo heev tiv thaiv kev co thiab kev cuam tshuam. Piv nrog rau vuam, txawm li cas los xij, riveting nthuav tawm ntau qhov tsis zoo: cov qauv tsim tau hnyav dua thiab ntau dua; cov rivet qhov cuam tshuam tus ntoo khaub lig-sectional zog ntawm cov khoom sib koom los ntawm 15% mus rau 20%; kev ua haujlwm suav nrog kev siv zog ntawm lub cev thiab ua kom muaj suab nrov; thiab tag nrho cov khoom siv tau zoo yog qhov tsawg. Yog li ntawd, nyob rau hauv cov nqe lus ntawm kev lag luam efficiency thiab kev sib koom ua ke nruj, riveting feem ntau poob qis ntawm vuam.
