Uhlobo oluhlukile lwe-bolt
Umehluko phakathi kwama-bolts nezikulufa ulele ezicini ezimbili: Ingxenye eyodwa, ingxenye ye-BOST ye-BOLT iyadingeka ngokuqinile ukuba yi-cylindrical, kepha ingxenye yesikulufo kwesinye isikhathi i-conical noma ngethiphu; Enye ukusebenzisa umsebenzi, isikulufa siklwebekile kwizinto eziqondiwe esikhundleni se-nati. Esikhathini esiningi, ama-bolts nawo asebenza ngawodwana, futhi ahlelwe ngokuqondile emgodini ofakwe kwangaphambili, ngaphandle kwesidingo sokusebenzisana nayo. Ngalesi sikhathi, iBolt ihlukaniswa njengesikhafu ngokuya ngomsebenzi.
Ukwakheka nenhloso yekhanda le-bolt ahlukaniswe ngama-hexagonal head bolts, ama-bolts amakhanda ayisigamu, ama-bolts amakhanda aphakathi nendawo, ama-bolts anezimbobo, i-hook head (isisekelo) ama-bolts nokunye.
Intambo yekholomu ingahlukaniswa ngentambo ehlanganayo, intambo ecolekileyo nentambo ye-intshi, ngakho-ke ibizwa ngokuthi yi-bolt ne-inch bolt.
Inqubo yokukhiqiza
Okokuqala, i-punch yokuqala ihamba ukulungiselela ucingo ukuze kwakhiwe, bese kuthi i-punch yesibili iqhubekela phambili kokulungiselela ucingo futhi yalolokisa umkhiqizo ophelile. Enqubweni yesihloko esibandayo, ukushona okulungisiwe (ukucindezelwa kufa) kanye nesitembu (ukuthambisa) kufa (ukubhoboza)
Inani lamakhanda) alifani. Ezinye izikulufo eziyinkimbinkimbi zingadinga ama-punches amaningi ukuze akhe ndawonye, adinga imishini yesiteshi esiningi ukwenza isikulufa sokwakha i-punch, kepha ingxenye yesikulufa isiqediwe, kepha ingxenye yesikulufa ayizange ibe ntambo. I-Thread Rolling ukusetshenziswa kwezinto ezimbili ezijikelezayo ezijikelezayo zifafaze (amapuleti okuhlikihla) ngamazinyo ahlanganisiwe ukuze anciphise i-cylindrical Blank eyakhiwe yi-Amulti-Station noma umshini wokuhola phakathi.
Ngemuva kwesihloko nokuhlikihla amazinyo, isikulufa sonke senziwe. Vele, ukuze wenze ukubukeka kwesikulufu kugqame futhi kube ngcono, inqubo yokwelashwa engaphezulu ivame ukwenziwa. Njengokuhlanza nokuphumelela kwezikulufo zensimbi ezingagqwali, i-electroplating ebusweni bezikulufo zensimbi yekhabhoni, njll. Kwenziwe ngemibala ehlukahlukene ye-screw fasteners.
