Tus kheej-tapping screws yog fasteners uas tsim los yog txiav lawv tus kheej cov xov sab hauv ua ntej-drilled qhov nyob rau hauv metallic los yog non{2}}cov ntaub ntawv hlau. Piv nrog rau kev sib txuas ntawm cov ntsia hlau ib txwm, tus kheej- threading screws tsis tas yuav tsum tau ua ntej -drilled threads thaum lub sij hawm installation, yog li muab qhov zoo tshaj plaws hauv kev sib dhos ua haujlwm, kev sib txuas kev ntseeg tau, thiab kev tiv thaiv -loosing kev ua tau zoo. Nrog rau lawv lub zog tensile siab, ib qho -cov khoom sib dhos, thiab cov qauv yooj yim, tus kheej -drilling screws yog siv dav hauv kev tsim khoom, kev tsim vaj tsev, khoom siv hauv tsev, thiab kev lag luam hluav taws xob.
Los ntawm txoj kev xav engineering, thaum lub sij hawm sib dhos, cov xov thiab lub qhov phab ntsa cov ntaub ntawv undergo yas deformation los yog txiav txiav, tsim ib tug ruaj khov mechanical locking qauv ntawm cov ntsia hlau thiab cov khoom siv hauv paus. Qhov no tus kheej - kev sib txuas txoj kev ua rau tus kheej -tapping fastening ib tug nyiam xaiv nyob rau hauv ntau lub teeb structural designs.
Daim ntawv thov kev lag luam ntawm tus kheej -tapping xov- ua cov ntsia hlau tuaj yeem taug qab mus rau thaum ntxov xyoo pua 20th. Cov qauv tsim thaum ntxov tau muab los ntawm cov qauv ntoo ntsia hlau, feem ntau yog siv cov hlau carburizable thiab muaj cov tails thiab cov xov sib sib zog nqus. Cov khoom thaum ntxov tau siv los txuas cov ntawv nyias nyias, yog li lub npe "cov ntawv hlau ntsia hlau" hauv engineering. Nrog rau kev nce qib hauv kev tsim thev naus laus zis thiab cov khoom siv engineering, tus kheej -tapping fasteners tau maj mam hloov mus rau ntau hom qauv, tsis tu ncua hloov mus rau ntau qhov chaw thov.
Los ntawm kev txhim kho thev naus laus zis, qhov kev hloov pauv ntawm cov txheej txheem ntawm cov ntsia hlau drilling tuaj yeem muab faib ua plaub theem: xov sib sau, tus kheej-tapping txiav, xov dov, thiab tus kheej-drilling qauv. Txhua theem ntawm kev ua tau zoo thev naus laus zis tau tsav kev txhim kho hauv kev ua haujlwm nrawm thiab nthuav dav nws cov ntawv thov engineering.
Thawj hom yog Tus Kheej -Screw Screw. Cov ntsia hlau no yuav tsum tau ua ntej -drilling ua ntej kev teeb tsa. Cov khoom nyob rau hauv lub qhov phab ntsa undergoes yas ntws vim lub compression thaum lub sij hawm screwing, tsim ib tug mating internal xov. Vim tias cov qauv no tso siab rau cov yas deformation ntawm cov khoom, nws yog qhov tsim nyog rau cov ntawv nyias lossis cov hlau uas muaj qee qhov ductility.
Nrog kev hloov pauv engineering daim ntawv thov ib puag ncig, kev siv tau ntawm tus kheej ib txwm siv -tapping fastening screws hauv cov ntaub ntawv tuab lossis tawv dua tau dhau los txwv. Txhawm rau daws qhov teeb meem no, kev lag luam tau tsim Tus Kheej - Txiav Ntsia Hlau. Cov qauv no nta ib tug txiav zawj ntawm qhov kawg ntawm cov xov, tso cai rau cov ntsia hlau txiav cov khoom zoo li tus kais thaum lub sij hawm screwing, yog li tsim ib qho xov hauv. Cov khoom siv no yog tsim rau cov phaj tuab lossis cov ntaub ntawv nkig thiab muaj qhov tseem ceeb ntawm cov khoom siv hauv kev tsim khoom.
Cov Xov Xwm sai tom ntej-Kev Tsim Cov Ntsiab Lus tau txhim kho kev ua haujlwm ntxiv. Qhov kev tsim no, los ntawm cov xov xov tshwj xeeb thiab cov qauv kawg, tso cai rau cov ntsia hlau los tsim cov xov sab hauv los ntawm dov thaum lub sij hawm screwing. Piv nrog rau cov ntawv ib txwm siv- hom screws, cov qauv dov muaj kev sib txhuam qis dua, kev tswj tau yooj yim ntawm kev teeb tsa lub zog, thiab kev sib txuas ntau dua. Kev ruaj ntseg ntawm ceev ceev- xov screws tau ua rau lawv yog ib yam tseem ceeb ntawm fastener nyob rau hauv cov qauv kev sib txuas.
Hauv qee daim ntawv thov, kev tsim kho tau zoo tuaj, xws li tus kheej -drilling thiab self- ua cov ntsia hlau. Qhov kev tsim no ua ke nrog cov drilling thiab xov- tsim cov thev naus laus zis, tso cai rau cov ntsia hlau ncaj qha los ua cov xov sib txuas tom qab nkag mus rau cov khoom siv, txo cov sij hawm sib dhos thiab cov nqi tsim kho.
Hauv kev tsim vaj tsev, cov phab ntsa ntub dej feem ntau siv ceev - ua cov ntsia hlau rau tapping, muaj cov duab tshwj xeeb lub taub hau thiab cov qauv xov. Cov khoom no tuaj yeem nkag mus sai sai rau cov khoom siv thaum lub sijhawm teeb tsa thiab tsim kev sib txuas ruaj khov hauv cov qauv steel ncej.
Los ntawm kev txhim kho tag nrho, kev nce qib thev naus laus zis hauv Tus Kheej -Tshuaj Xov-Txoj Screws yog qhov tseem ceeb hauv peb yam. Ua ntej, txhim kho cov khoom siv, ua tiav los ntawm kev kho cua sov thiab cov thev naus laus zis los txhim kho cov ntsia hlau hardness thiab hnav tsis kam. Thib ob, optimized xov qauv, ua tiav los ntawm geometric tsim los txo cov kev sib txuas torque thiab ua kom muaj zog txuas ntxiv. Thib peb, txhim kho cov txheej txheem tsim khoom, suav nrog lub taub hau txias, qhov tseeb xov dov, thiab cov cuab yeej siv tshuaj ntsuam xyuas, tsis tu ncua kev txhim kho cov khoom zoo.
Raws li kev lag luam kev lag luam txav mus rau kev ua haujlwm siab dua thiab kev siv tshuab hluav taws xob, Auto-Drilling thiab Self-Tapping Screws tau ua lub luag haujlwm tseem ceeb hauv kev sib dhos niaj hnub. Los ntawm cov khoom siv hluav taws xob mus rau cov tsev loj loj, los ntawm cov khoom siv sib zog mus rau cov tshuab siv tshuab, lawv cov kev ua haujlwm siab, tus nqi qis, thiab kev sib txuas ua tau zoo yuav nyob twj ywm yam khoom tseem ceeb hauv kev lag luam fastener.
