Izikrufu ezincinci zilukiweyo ebomini bethu. Abanye abantu banokukhanyela oku, kodwa sisebenzisa izinto ezinezikrufu kuzo yonke imihla. Ukusuka kwizikrufu ezincinci kwiifowuni ze-smart ukuya kwiziqhoboshi kwiinqwelomoya nakwiinqanawa, siyakonwabela ukukhululeka kwezikrufu ngalo lonke ixesha. Emva koko kuyimfuneko ukuba sazi i-ins kunye nokuphuma kophuhliso lwe-screw.
Imvelaphi yokuqala
Izikrufu ziyimveliso yoluntu lwezoshishino. Kunzima ukukhangela ukuveliswa kwesikrufu sokuqala namhlanje, kodwa izikrufu zentsimbi zazisetyenziswa njengeziqhoboshi eYurophu ubuncinane ngenkulungwane ye-15. Kodwa ngelo xesha, inkqubo yokuvelisa izikrufu yayinzima kakhulu kwaye ibiza kakhulu, ngoko ke izikrufu zazinqabile kwaye zingasetyenziswanga kakhulu.
Inkqubela phambili enkulu
Ekupheleni kwenkulungwane ye-18, kwenziwa inkqubela enkulu ekuvelisweni nasekusetyenzisweni kwezikrufu. Ngo-1770, umenzi wesixhobo u-Jesse Ramsden wenza i-screw lathe yokuqala, eyaphefumlela ukuveliswa komatshini wokujija. Ngo-1797, uMaudsley wenza i-all-metal precision screw lathe. Kunyaka olandelayo, uWilkinson wavelisa umatshini wokwenza iinati kunye nebholithi. Ngeli xesha, izikrufu zazithandwa kakhulu njengendlela yokulungiswa, kuba indlela engabizi kakhulu yokuvelisa ifunyenwe.
Uphuhliso lwexesha elide
Ngenkulungwane ye-20, iintlobo ezahlukeneyo zeentloko ze-screw zavela. Ngomnyaka we-1908, isikrufu seRobertson esinentloko yesikwere sasithandwa ngenxa yeempawu zayo ezichasayo ngexesha lofakelo. Ngo-1936, isikrufu sentloko sikaPhillips saqanjwa kwaye sanikwa ilungelo elilodwa lomenzi wechiza. Yahlala ixesha elide kwaye iqinile kunesikrufu saseRobertson.
Emva kwenkulungwane ye-21, iintlobo ze-screws zihluke kakhulu kwaye isicelo silungile. Izikrufu ezahlukeneyo ziya kusetyenziselwa iimeko ezahlukeneyo, ezifana nezindlu, iimoto, iiBridges, njl., kunye nezixhobo ezahlukeneyo ezifana nentsimbi, iinkuni, i-drywall, njl njl.
Ukuba ufuna izikrufu okanye iziqhoboshi zesiko, sinayo le nto uyifunayo. U-Fasto uneminyaka eyi-20 yamava ekuveliseni nasekuthengiseni i-fasteners. Siza kukubonelela ngenkonzo eyanelisayo.
