Isingeniso somsebenzi we-Fastener
Ama-fasteners ahlukaniswe ama-fasteners ane-threaded and non-threaded fasteners, ama-fastened non-threaded ikakhulukazi abhekisela kuma-rivets, izikhonkwane ezishiselwe, izikhonkwane zokuxhuma, njll.Okubizwa ngokuthi uxhumano lwe-threaded luwukusetshenziswa kwezibopheli ezinezintambo ukuze kuhlanganiswe izingxenye ezimbili noma ngaphezulu ezixhunyiwe ndawonye, ukuze umelane nemithwalo ehlukahlukene yangaphandle, futhi izingxenye ezixhunyiwe azihlukani, azisheleli, noma indawo ehlangene ayivuzi.Ngenxa yalesi sizathu, ngaphambi kokusebenzisa umthwalo wangaphandle, ama-fasteners anezintambo kudingeka aqiniswe ukuze aqinise izingxenye ezixhunyiwe.Ukuqiniswa kwezibophelelo ezinentambo kubizwa ngokuthi i-pretightening, futhi amandla abizwa ngokuthi i-axial pretightening.
Umgomo wokukhetha ama-fasteners
Ukukhethwa kokucaciswa kwe-fastenerNgemva kokukhetha izinhlobonhlobo zezixhumi, imininingwane edingekayo kufanele futhi ikhethwe ezinhlobonhlobo.Imininingwane kufanele inqunywe ngokuya ngezidingo zephrojekthi noma ukukhiqizwa kanye nomkhiqizo wokuklama ukuxhuma, futhi izimiso okufanele zicatshangelwe ngokuvamile zinalokhu okulandelayo 3: Ukucaciswa kwe-Fastener (okuhlanganisa ububanzi nobude) kufanele kukhethwe ochungechungeni olusohlwini lwe- i-fastener standard.Uma izinga linochungechunge losayizi abangaphezu kwababili, uchungechunge lokuqala noma uchungechunge lwezicaciso zempahla kufanele kucatshangelwe.Ngokuvamile, akulungile ukukhetha izicaciso zobude ngaphandle kwalezo ezishiwo ezingeni.Uma ibhawudi lihambisana namantongomane, ubude bebhawodi kufanele bulandele isimiso sokuthi ibhawodi liphuma enati izikhathi ezi-2-3 kunephimbo (kuhlanganise ne-chamfer), kodwa ubude bebhawodi akumele bube bukhulu kuno-10d (d ububanzi obujwayelekile bebhawodi).Kusukela ekucatshangelweni kwezomnotho, ukucaciswa kwezinsimbi kufanele kuncishiswe ngangokunokwenzeka.Kuphrojekthi efanayo noma umkhiqizo, ngesisekelo sophenyo nocwaningo, ububanzi obufanele bokucaciswa kwezinto zokubopha bunganqunywa, futhi imininingwane engaphakathi kwebanga elifanele ingakhethwa ngokusemandleni.Ngivakashele inkampani yase-United States Peka umugqa wokuhlanganisa amaloli esindayo ngizizwa ngijule kakhulu: ingxenye ye-asi engemuva: Ukucaciswa kwe-M16 amabhawodi amazinyo amahle, ubude bunemininingwane eminingana;Uhlaka ngokuyinhloko lwakhiwe amazinyo ama-M16 ama-coarse 10.9 bolts nawo wonke amantongomane ensimbi, ubude bunezincazelo eziningana, futhi amantongomane afana ncamashi;Kunezinhlobo ezi-3 zezikulufu zekhanda kukhebhu, ubude besikulufu sekhanda ngalinye buyalingana, futhi izinga lokumiswa liphezulu kakhulu.
