Tapping screws tsim mating threads hauv cov ntaub ntawv uas lawv tau tsav mus rau hauv.Muaj ob hom kev yooj yim: xov sib sau thiab xov txiav.
Cov xov-forming ntsia hlau tshem cov khoom nyob ib ncig ntawm lub qhov pilot kom nws ntws nyob ib ncig ntawm lub screwâ??s threads.Cov ntsia hlau no feem ntau yog siv thaum xav tau kev ntxhov siab loj los ua kom tsis txhob xoob.Vim tias tsis muaj cov khoom raug tshem tawm, qhov mating qhov tsim kom haum nrog xoom clearance.Lawv feem ntau tsis xav tau cov tshuab ntxhua khaub ncaws lossis lwm yam khoom siv xauv kom tsis txhob xoob.
Xov-tapping screws muaj cov npoo thiab cov kab noj hniav uas tsim cov xov mating los ntawm kev tshem cov khoom ntawm qhov lawv tau tsav mus rau hauv.Cov screws??txiav txiav txhais tau hais tias torque xav tau rau kev ntxig yog tsawg.Cov ntsia hlau yog siv rau hauv cov ntaub ntawv uas cuam tshuam nrog kev ntxhov siab tsis xav tau, lossis thaum nws siv rau kev tsav tsheb ntau dhau los siv cov xov sib dhos.
Feem ntau, tapping screws tso cai nrawm nrawm vim tias tsis siv cov txiv ntoo thiab kev nkag tau tsuas yog yuav tsum tau los ntawm ib sab ntawm qhov sib koom ua ke.Mating threads tsim los ntawm cov tapping screws haum cov ntsia hlau threads ze, thiab tsis xav tau tshem tawm.Kev sib raug zoo feem ntau ua rau cov ntsia hlau nruj txawm tias muaj kev vibrations.
Taping screws feem ntau yog cov ntaub ntawv tawv thiab muaj lub zog tensile tsawg kawg yog 100,000 psi nrog rau qhov kawg siab torsional zog.Tapping screws yog siv nyob rau hauv steel, aluminium, tuag-castings, cam khwb cia hlau, forgings, yas, reinforced plastics, thiab resin-impregnated plywood.
Tapping screws yog muaj nrog cov ntxhib los yog cov xov zoo.Coarse threads yuav tsum tau siv nrog cov khoom tsis muaj zog.Cov xov zoo raug pom zoo yog tias ob lossis ntau qhov kev sib txuas xov tag nrho yuav tsum nyob saum lub qhov txiav, tab sis cov khoom tsis tuab txaus kom tso cai rau ob lub xov ntawm cov xov ntxhib.
