Uma i-rivet, uma ububanzi be-rivet bukhulu kakhulu, ukwakheka okucasulayo kunzima kakhulu, kulula ukwenza i-deformation yensimbi yeshidi. Ngokuphambene nalokho, uma ububanzi be-rivet buncane kakhulu, amandla e-rivet awanele, okuholela ekwandeni kwe-rivet. inani lama-rivets kanye nokuphazamiseka kokwakhiwa.
Indlela yokukhetha ububanzi be-rivet idinga ukubona usayizi we-aperture ye-rivet.Ngokuvamile, ububanzi be-rivet buyi-0.1-0.2mm enkulu kunobubanzi be-rivet.Uma ingaphezu kuka-0.2mm, ingase ixege.
Ukukhethwa kobubanzi be-rivet ngokuyinhloko kunqunywa ubukhulu bepuleti kanye nefomu le-rivet.Ikhwalithi ye-rivet ihlobene ngokuqondile nobude benduku ye-nail.Uma induku ye-nail ide kakhulu, ikhanda elicasulayo le-rivet lizoba likhulu kakhulu, futhi induku ye-nail izoba lula ukugoba.Nokho, uma induku ye-nail imfushane kakhulu, inani elicasulayo alanele futhi ikhanda le-rivet aliphelele, okuzothinta kakhulu amandla nokuqina kwejoyinti le-rivet.Ubude be-riveting kufanele bunqunywe ngokuvumelana nobukhulu obuphelele bezingxenye ezixhunyiwe, imvume yobubanzi phakathi kwembobo yezipikili kanye nenduku ye-nail kanye nenqubo yokugoqa.Ubude be-rivet rod ene-aperture evamile can can kubalwe ngokwefomula yefomu elihlangene le-rivet, futhi ubukhulu bepuleti ekubaleni ububanzi be-rivet kufanele futhi kunqunywe ngokuvumelana nesimiso.
Ukumataniswa kwe-rivet aperture kanye ne-rivet kufanele kunqunywe ngokuvumelana nezindlela ezahlukene ze-rivet ebandayo kanye ne-rivet eshisayo.Induku ye-nail akulula ukucasuka ngesikhathi se-riveting ebandayo.Ukuze kuqinisekiswe amandla okuxhuma, ububanzi bembobo yezipikili kufanele busondelene nenduku ye-nail.E-riveting eshisayo, ngoba i-rivet iyanda ekushiseni, i-plasticity ye-rivet iyanda futhi ubunzima bayo buyancipha.Ukuze kube lula ukuthungatha, umehluko phakathi kobubanzi bembobo yezipikili kanye nenduku yezipikili kufanele ibe mkhulu kancane.Ngokwe-riveting ye-multi-layer plate dense, ububanzi bomgodi wokubhoboza kufanele buncishiswe ngo-1-2mm njengobubanzi obujwayelekile.Ezingxenyeni ze-cylindrical, ububanzi bembobo kufanele buncishiswe ngo-L-2mm ​​uma kuqhathaniswa nobubanzi obujwayelekile ngaphambi kokugoba, ukuze ukubuyisela kabusha kungenziwa ngokuhambisana nezidingo zobuchwepheshe ngesikhathi sokuhlanganisa.
Izidingo zobuchwepheshe zembobo ye-rivet zifaka ukunemba kwembobo ye-rivet, ukunemba kwendawo kanye nekhwalithi ephezulu.Ukunemba kwembobo ye-rivet kubhekisela ekunembeni kobukhulu bobubanzi bembobo ye-rivet nobude bendawo, kanye nokunemba komumo we-diameter yembobo ye-rivet njengokuyindilinga, isilinda kanye ne-eksisi. ukuqondisa, futhi kuhlanganisa ukunemba kwembobo esesokhethini le-rivet ekhanda elishisiwe.Ukunemba kwendawo yezimbobo ze-rivet kukhombisa ngokuyinhloko ukubumbana phakathi kwezimbobo ze-rivet, ukucaba phakathi kwezimbobo zezinzipho kanye nokuvuleka kwendawo phakathi kwezimbobo zezinzipho kanye nonqenqema lwe-rivet. izingcezu.Isikhala sembobo yerivethi, izimfuneko zokunemba kwezikhala zesikhala semigqa kufanele zinqunywe ngokuvumelana nemingcele yokuqondanisa i-rivet ku-rivet.
Ngokuvamile, lapho isikhala phakathi kwezimbobo zezinzipho singeqi ku-30mm, ukuchezuka kwezikhala ku-±1.0mm.Lapho isikhala phakathi kwezimbobo zezinzipho singaphezu kuka-30mm, ukuchezuka kwesikhala singu-±1.5mm. ngokuvamile zingu ±1.0mm.Ikhwalithi engaphezulu yembobo ye-rivet ngokuyinhloko ibhekisela esimisweni esidingekayo sokuhwaqazeka kwendawo yangaphakathi yembobo ye-rivet, futhi ingaphezulu lembobo yezipikili alivunyelwe ukuba libe nama-burrs, imiphetho namakhona, umonakalo kanye nokuqhekeka. .
