Tus kheej- tho riveting (SPR) yog ib qho kev sib koom ua ke uas siv lub raj rivet txhawm rau txhawm rau daim ntawv sab sauv thiab nkag mus rau hauv daim ntawv qis hauv qab siab; lub rivet tus Tsov tus tw ces flares sab nraud los tsim tus kheej - xauv kev twb kev txuas, tshem tawm qhov xav tau rau pre-drilled qhov. Cov txheej txheem no tsim nyog rau kev koom nrog cov ntaub ntawv zoo sib xws lossis tsis sib xws-xws li aluminium thiab steel sheets-thiab muaj qhov zoo xws li kev huv, fume- ua haujlwm dawb, yooj yim ntawm automation, thiab cov pob qij txha nrog dej siab thiab corrosion kuj.
Txhawm rau txhim kho kev sib koom ua haujlwm, cov lej simulations siv DEFORM- 3D finite element software feem ntau siv los ua kom zoo dua qhov tsis xws li rivet phab ntsa thickness, qhov siab, thiab qhov sib piv ntawm centripetal. Cov khoom siv rau cov txheej txheem no, xws li hydropneumatic tus kheej- tho riveting tshuab, muaj kev pab cuam ntau yam kev siv zog, tsis tu ncua kev siv zog, thiab kev txhawb zog ntau ntxiv. rivet hom, suav nrog semi-tubular, tubular, thiab elliptical tubular rivets.
