Self-tapping ntsia hlau yog ib hom ntsia hlau siv los txuas cov ntaub ntawv hlau thiab daim hlau.Nws muaj ntau hom, xws li tus kheej tapping tus pin ntsia hlau, phab ntsa nws tus kheej tapping ntsia hlau, nws tus kheej tapping ntsia hlau, lauj kaub taub hau thiab hexagon taub hau nws tus kheej tapping ntsia hlau, thiab lwm yam. Txhua tus kheej tapping ntsia hlau muaj kev siv sib txawv.Tom ntej no, peb yuav qhia luv luv txog cov no.
1. Self-tapping fastening screws kuj yog siv los txuas cov hlau nyias nyias.Cov xov yog ib hom xov uas muaj ib qho arc daim duab peb sab, thiab txheej txheej ntawm cov xov kuj muaj tus qauv siab hardness.Yog li ntawd, thaum lub sij hawm kev twb kev txuas, cov ntsia hlau tseem tuaj yeem coj mus rhaub cov xov sab hauv hauv qab lub qhov ntawm cov xov ntawm qhov txuas, yog li tsim kev sib txuas.Hom ntsia hlau no yog tus cwj pwm los ntawm cov ntsia hlau qis-hauv torque thiab cov yam ntxwv siab xauv.Nws muaj cov yam ntxwv ua haujlwm zoo dua li qhov zoo tib yam tus kheej tapping screws thiab tuaj yeem siv tsis siv lub tshuab screws.
2. Lub phab ntsa vaj huam sib luag tus kheej tapping ntsia hlau yog siv los ua kev sib txuas ntawm gypsum phab ntsa vaj huam sib luag thiab cov hlau keel.Cov xov yog ob lub taub hau, thiab txheej txheej ntawm cov xov kuj muaj tus qauv siab hardness (≥ HRC53), uas tuaj yeem ntsia tau sai rau hauv keel yam tsis tau ua qhov prefabricated qhov, yog li tsim kev sib txuas.
3. Qhov txawv ntawm nws tus kheej tapping ntsia hlau thiab dav nws tus kheej tapping ntsia hlau yog tias kev sib txuas ntawm tus kheej tapping ntsia hlau yuav tsum mus los ntawm ob txoj kev: drilling (drilling xov hauv qab qhov) thiab tapping (xws li fastening txuas);Thaum tus kheej-drilling tus kheej-tapping ntsia hlau txuas nrog, ob txheej txheem ntawm drilling thiab tapping yog ua ke.Nws thawj zaug siv lub laum me ntsis nyob rau hauv pem hauv ntej ntawm lub hau ntswj kom tiav qhov drilling, thiab tom qab ntawd siv cov ntsia hlau los ua kom tiav cov tapping (nrog rau kev sib txuas ntawm fastening), uas txuag lub sij hawm tsim kho thiab txhim kho kev tsim kho.
4. Lub taub hau thiab hexagon-lub taub hau nws tus kheej tapping screws yog tsim nyog rau qhov chaw uas lub laum me ntsis raug tso cai kom raug.Hexagon-head self-tapping screws tuaj yeem muaj lub zog loj dua li lub taub hau ntawm tus kheej tapping screws.Lub taub hau countersunk thiab hexagon socket taub hau tapping screws yog tsim nyog rau qhov chaw uas lub taub hau ntsia hlau tsis tuaj yeem raug.Lub hexagon socket lub taub hau tapping screws tuaj yeem dais ntau lub zog dua li lub taub hau tapping screws;Lub taub hau semi-sunk self-tapping ntsia hlau yog qhov tsim nyog rau qhov chaw uas lub taub hau ntsia hlau raug tso cai kom raug me ntsis.Thaum sib dhos thiab disassembled tus kheej tapping screws, slotted self-tapping screws yuav tsum siv slotted screwdrivers, cross-recessed nws tus kheej tapping screws yuav tsum siv ntoo khaub lig-shaped screwdrivers, hexagonal torx self-tapping screws yuav tsum siv hexagonal torx wrenches, thiab hexagonal self-tapping. Cov ntsia hlau yuav tsum siv cov khoom siv tes ua, lub nplhaib wrenches, lub qhov (socket wrenches) lossis cov khoom siv kho tau.
