Xa i-rivet, ukuba ububanzi be-rivet bukhulu kakhulu, ukuphazamisa ukwenza kunzima, kulula ukwenza i-sheet metal deformation. Ngokuchasene noko, ukuba ububanzi be-rivet buncinci kakhulu, amandla e-rivet awanelanga, okukhokelela ekwandeni kwe-rivet. inani lee-rivets kunye nokuphazamiseka kokwakhiwa.
Indlela yokukhetha ububanzi be-rivet kufuneka ubone ubungakanani be-aperture ye-rivet.Ngokuqhelekileyo, ububanzi be-rivet yi-0.1-0.2mm enkulu kunobubanzi be-rivet.Ukuba ingaphezulu kwe-0.2mm, inokukhululeka.
Ukukhethwa kobubanzi be-rivet ubukhulu becala bunqunywe ngubukhulu beplate kunye nefom ye-rivet.Umgangatho we-rivet uhambelana ngokuthe ngqo nobude bentonga ye-nail.Ukuba intonga yesikhonkwane ide kakhulu, intloko ephazamisayo ye-rivet iya kuba nkulu kakhulu, kwaye intonga ye-nail iya kuba lula ukugoba.Nangona kunjalo, ukuba intonga ye-nail ifutshane kakhulu, isixa esiphazamisayo asanelanga kwaye intloko ye-rivet ayiphelelanga, okuya kuchaphazela ngokunzulu amandla kunye nokuqina kwe-rivet joint.Ubude be-riveting kufuneka bugqitywe ngokuhambelana nobukhulu obupheleleyo beendawo ezidibeneyo, ukukhutshwa kobubanzi phakathi komngxuma wezikhonkwane kunye nentonga yesikhonkwane kunye nenkqubo yokukhwela. zibalwe ngokwefomula yefom edibeneyo ye-rivet, kwaye ubukhulu bepleyiti ekubaleni ububanzi be-rivet kufuneka bumiselwe ngokomgaqo.
Ukuhambelana kwe-rivet aperture kunye ne-rivet kufuneka kunqunywe ngokweendlela ezahlukeneyo ze-rivet ebandayo kunye ne-rivet eshushu.Intonga ye-nail ayilula ukucaphukisa ngexesha lokubanda okubandayo.Ukuze kuqinisekiswe amandla okudibanisa, ububanzi bomngxuma wesikhonkwane kufuneka busondele kwintonga yesikhonkwane.Kwi-riveting eshushu, kuba i-rivet iyanda ekushiseni, i-plastiki ye-rivet iyanda kwaye ubunzima bayo buyancipha.Ukuze kube lula ukudibanisa, umahluko phakathi kobubanzi bomngxuma wezikhonkwane kunye nentonga yesikhonkwane kufuneka ibe nkulu kancinane. Kwi-multi-layer plate dense riveting, ububanzi bomngxuma wokubhobhoza kufuneka buncitshiswe nge-1-2mm njengobubanzi obuqhelekileyo.Kumacandelo e-cylindrical, ububanzi bomngxuma kufuneka buncitshiswe ngu-L-2mm ​​xa kuthelekiswa nobubanzi obuqhelekileyo ngaphambi kokugoba, ukwenzela ukuba ukubuyisela kwakhona kuqhutywe ngokuhambelana neemfuno zobugcisa ngexesha lokuhlanganisa.
Iimfuno zobugcisa zomngxuma werivet zibandakanya ukuchaneka komngxuma werivet, ukuchaneka kwendawo kunye nomgangatho womphezulu. Ukuchaneka komngxuma werivet kubhekiselele ekuchanekeni komngxuma werivet ukuchaneka kwesangqa somngxuma werivet kunye nobude becala, kunye nokuchaneka kokuchaneka kwedayamitha yomngxuma werivet njengokungqukuva, isilinda kunye ne-axis. ukuchaneka, kwaye iquka ukuchaneka komngxuma kwisokethi ye-rivet ye-countersunk head hole.Ukuchaneka kwendawo ye-rivet hole ibonisa ubukhulu becala ukubambisana phakathi kwemingxuma ye-rivet Iingcezu.Isithuba somngxuma werivet, isithuba somda kunye neemfuno zokuchaneka kwezithuba zemiqolo kufuneka zigqitywe ngokweeparamitha zolungelelwaniso lwerivet kwirivet.
Ngokubanzi, xa isithuba phakathi kwemingxuma yezikhonkwane singekho ngaphezulu kwe-30mm, ukutenxa kwesithuba ku-±1.0mm.Xa isithuba phakathi kwemingxuma yezikhonkwane singaphezulu kwe-30mm, ukutenxa kwesithuba yi-±1.5mm. ngokubanzi ziyi-±1.0mm.Umgangatho womphezulu womngxuma we-rivet ikakhulu ubhekiselele kuburhabaxa bomphezulu bemfuno kumphezulu wangaphakathi womngxuma we-rivet, kwaye umphezulu womngxuma wezikhonkwane awuvumelekanga ukuba ube nemibhobho, imiphetho neekona, ukonakala kunye neentanda. .
