IiRivets, njengeziqhoboshi ezibalulekileyo kuqhagamshelo koomatshini, zisetyenziswa kakhulu kwindawo yokubhabha, iimoto, kunye nolwakhiwo lwezakhiwo. Ukukhetha i-rivet efanelekileyo akuchaphazeli kuphela ukuthembeka koqhagamshelwano kodwa kuchaphazela ngokuthe ngqo ukhuseleko kunye nokuqina kwesakhiwo sonke. Eli nqaku liza kuxoxa ngendlela yesayensi yokukhetha iirivets ezisekelwe kwizinto eziphathekayo, iinkcukacha, uhlobo, kunye nendawo yokusebenza.
1. Ukukhethwa kwezinto
Isixhobo se-rivet kufuneka simiselwe ngokusekelwe kumandla, ukuxhathisa ukubola, kunye neemfuno zokushisa kwesicelo. Izinto eziqhelekileyo ziquka i-aluminiyam ialloy (ikhaphukhaphu kunye ne-corrosion{1}}i-resistant), intsimbi (amandla aphezulu), i-stainless steel (i-corrosion{2}}resistant), kunye nobhedu (i-conductivity elungileyo). Umzekelo, -amandla aphezulu we-aluminium alloy okanye i-titanium alloy rivets zihlala zisetyenziswa kwishishini le-aerospace, ngelixa i-stainless steel okanye ii-plated rivets zikhethwa kwiindawo zaselwandle ukunqanda irusi.
2. Ukuhambelana kweNkcazo
Ububanzi kunye nobude be-rivet kufuneka buhambelane ngokuchanekileyo nobukhulu kunye nobubanzi bomngxuma wezinto ezidityanisiweyo. Iirivethi ezibhityileyo kakhulu zinokubangela ukuba uqhagamshelo lube buthathaka, ngelixa iirivethi ezishinyene kakhulu zinokusilela ukufakela okanye ukonakalisa umsebenzi. Ngokuqhelekileyo, ububanzi be-rivet kufuneka bube ngu-1.5 ukuya ku-2 ubukhulu beplate, kwaye ubude kufuneka bugubungele ubukhulu obudibeneyo bamacwecwe omabini kunye nesibonelelo esithile sentloko.
3. Ukuhambelana kohlobo
Iirivethi ziza kwiindidi ezahlukeneyo, kuquka iirivethi eziqinileyo (isincamathelisi esisisigxina), iirivethi ezingaboniyo ({0}}ufakelo olusecaleni), iirivethi ezingaboniyo (ezilungele iindawo ezingabonakaliyo-ezibonakalayo), kunye nokuqhuma{2}}iirivethi zobungqina (kwiimfuno ezizodwa zokhuseleko). Umzekelo, ukulungisa iimoto kusoloko kusebenzisa iirivethi ezingaboniyo ukukhawulezisa, ukufakela okukodwa -kwamacala, ngelixa izakhiwo zebhulorho zixhomekeke kwi{5}}iirivethi eziqinileyo eziphezulu zozinzo{6} lwexesha elide.
4. Ukuhambelana kokusingqongileyo
Ubushushu obuphezulu-, ukungcangcazela, okanye ubume bendawo ebolileyo bufuna iirivethi eziyilwe ngokukodwa. Umzekelo, i-nickel-based alloy rivets ingasetyenziselwa{3}}ubushushu obuphezulu bezicelo, ngelixesha iimoritha ezingcangcazelayo zicebisa ukongeza{4}}imilinganiselo yokukhulula. Usetyenziso lwemichiza lufuna iirivethi ezineasidi{6}} kunye nealkali{7}}ekwaziyo ukuvaleka.
Isishwankathelo
Ukukhetha i-rivet kufuna ukuqwalaselwa ngokubanzi kweempawu eziphathekayo, ukuchaneka kwenkcazo, uhlobo kunye nomsebenzi, kunye neemeko zokusingqongileyo. Ukubonisana nabanikezeli beengcali, ukubonisana nemigangatho yobunjineli (efana ne-ISO okanye i-GB), kucetyiswa ukuba kuqinisekiswe ukuba i-rivet ihambelana kakhulu neemfuno zesicelo esithile, iqinisekisa uxhulumaniso olukhuselekileyo nolusebenzayo.
