Ukumelana nokuxegiswa Kokuxhunywa Kwe-Fastener Enentambo

Ukuxhumeka okunemicu kungase kube ngaphansi kwazo zonke izinhlobo zemithwalo eguquguqukayo ezimeni zokusebenza, okuhlanganisa ukudlidliza okuqine kakhulu kanye nemithwalo enomthelela. Ngaphansi kwesenzo semithwalo eguquguqukayo, ukwehluleka kokuxhuma okufakwe imicu ngokuvamile kubangelwa ukuxega kwabo kanye nokulimala kokukhathala. Ngokuvamile, ukuphila kokunqanda ukudlidliza kokuxhunywa kwentambo kufushane kakhulu kunempilo yokukhathala kwezinto zabo nezakhiwo. Kudala ngaphambi kokulimala kokukhathala, ukwehluleka ukuxegiswa kokuxhuma okufakwe imicu ngenxa yokuxega kwenzeke, noma ukulimala ngaphambi kwesikhathi kwezixhumi nezingxenye ezixhunyiwe ngenxa yokuxega kwenzekile. Ukwehluleka kokuxhumana okunentambo kuzothinta ukusebenza okuvamile kwemikhiqizo nemishini, futhi kungase kubangele ngisho nemiphumela emibi kakhulu. Ukuvimbela kanjani ukuxegiswa kokuxhuma okunentambo kungomunye wemisebenzi ebalulekile ekuthuthukisweni nasekuklanyweni kwezibophelelo ezinentambo.

Kunezinhlobo ezintathu eziyisisekelo zezindlela zokulwa nokuxegiswa zokuxhunywa kwezibophelelo ezinentambo:

1. I-Non-Detachable Anti-Loosening

Lena indlela emelene nokuxegiswa esebenzisa i-welding, i-bonding noma i-punching riveting ukuze iguqule uxhumo olukhiphekayo oluluchungechunge lube uxhumo olungenakususwa. Kuyindlela ethembekile yendabuko yokulwa nokuxegisa. Ububi bayo ukuthi izibophelelo ezinentambo azikwazi ukuphinda zisetshenziswe. Futhi ukuhlinzwa kunzima. Ivame ukusetshenziswa kwezinye izikhathi ezibalulekile ezidinga ukuthembeka okuphezulu ekunqandeni ukuthukulula ngaphandle kokuhlakazeka.

• Ukushisela: I-nati ishiselwe kubhawodi noma isibambiso endaweni yokusebenza.

• Ukuhlanganisa: Faka izinto ezinamathelayo ezifana ne-epoxy resin noma i-anaerobic adhesive endaweni ehambisanayo yentambo. Ngemuva kokuthi i-adhesive iphulukisiwe, ingakwazi ukubopha ngokuqinile izintambo ezifanayo ukuze kuzuzwe injongo yokukhiya nokuvimbela ukukhululeka. Izinamatheliso ezihlukene zivame ukuba namakhono ahlukene okukhiya. Izixhumi ezimbozwe nge-epoxy resin zinamandla okubopha okuphezulu futhi azikwazi ukuhlakazwa. Izinsimbi eziboshwe nge-anaerobic adhesive zingahlakazwa, kodwa ingcina esele phezu kwentambo ngemva kokuhlakazwa kunzima ukuyihlanza, futhi intambo ingase yonakaliswe, ngakho-ke izinsimbi akufanele ziphinde zisetshenziswe.

• Ukubhoboza/Ukugoba:Indlela ye-punch riveting isetshenziselwa ukubangela ukuwohloka kwendawo kwebhawodi (noma isikulufu) namantongomane ngemva kokuqiniswa ukuze kuvinjwe ukuthi zingaxegi. Uxhumano luthembekile futhi lungasetshenziswa kunoma yikuphi ukuxhumana okungadingi ukuqaqa.

2. I-Anti-Loosing of Mechanical Fasteners
