Isikulufa:
Isikulufu siwuhlobo lwe-fastener, ngandlela thile efana nebhelethi, ngokuvamile elenziwe ngensimbi, futhi libonwa ngegeja elinamandla, elaziwa ngokuthi intambo yesilisa (intambo yangaphandle). Izikulufo zisetshenziselwa ukubopha izinto zokwakha ngokumba ngaphakathi nangokuthi ziguqulwe zibe yinto lapho ijika, kuyilapho intambo isika ama-grooves entweni eboshwe angasiza ukudonsa izinto eziboshwe ngokuqinile futhi zivikele ukuphuma. Kukhona izikulufa eziningi zezinto zokwakha ezahlukahlukene; lezo ezivame ukuqiniswa izikulufu zifaka ukhuni, ishidi lensimbi, nepulasitiki.
Isikulufu sivame ukuba nenhloko emaphethelweni aqukethe ukwakheka okukhethekile okuvumela ukuthi iguqulwe, noma iqhutshwe , ngethuluzi. Amathuluzi ajwayelekile wokusebenzisa ama-screws okushayela afaka ama-screwdrivers kanye nama-wrenches. Ikhanda livame ukuba likhudlwana kunomzimba wesikulufu, okugcina isikhafu singahanjiswa ngokujule ngaphezu kobude besibazi nokunikeza indawo ethwele.
Isikulufu sokhuni:
Izikulufu zokhuni zakuqala zenziwa ngesandla, nochungechunge lwamafayela, amakhoseli, namanye amathuluzi okusika, futhi lezi zingabonakala kalula ngokunaka ukungalingani nokwakheka kwemicu, kanye namamaki wamafayela asele ekhanda lesikulufu. nasendaweni ephakathi kwentambo. Eziningi zalezi screw zazinamaphethelo agqamile, zingenalo iphuzu elibukhali le-tapered cishe kuzo zonke izikulufu zokhuni zanamuhla. Ekugcineni, kwasetshenziswa ama-lathes ukwenza izikulufa zokhuni, futhi kwaqoshwa i-patent yokuqala ngo-1760 eNgilandi. Ngesikhathi seminyaka yama-1850 amathuluzi okufunga afungelwa ukwenziwa umucu ofanayo nowokufana. Izikulufa ezenziwe ngalawa mathuluzi zinezigodi eziyindilinga ngemicu ebukhali neqinile. Ezinye izikulufa zokhuni zenziwa ngokusikwa kufwa njengasekupheleni kweminyaka yama-1700s (mhlawumbe nangaphambi kuka-1678 lapho okuqukethwe incwadi kwakushicilelwa izingxenye ezithile).
Lapho imishini yokujika isikulufu isisetshenziswa ngokujwayelekile, izikulufu zezinkuni ezitholakala kakhulu kwezohwebo zenziwa ngale ndlela. Lezi zikulufa zezinkuni ezisikiwe zicishe zithintwe ngokunganqamuki, futhi noma ngabe i-tapered shank ingabonakali, ziyakwazi ukubonwa ngoba izintambo azidluli ukudlula ububanzi be-shank. Izikulufo ezinjalo zifakwa kangcono kakhulu ngemuva kokumba umgodi wokushayela ngesicubu somshini we-tapered. Iningi lezikulufo zanamuhla zokhuni, ngaphandle kwalezo ezenziwe ngethusi, zakhiwa kwimishini yokugaya intambo. Lezi zibazi zinobubanzi obungaguquki, imicu enobubanzi obukhulu kune-shank, futhi inamandla ngoba inqubo yokugoqa ayiguguli okusanhlamvu kwensimbi.
Noma yisiphi isidingo sicela uxhumane nathi.
