Dab tsi "Self-Tapping" Tiag Tiag
Ib tus kheej-tapping ntsia hlau txiav los yog tsim nws tus kheej cov xov sab hauv raws li nws tau tsav mus rau hauv cov khoom siv - uas yog qhov ua rau nws "tus kheej-tapping." Tab sis muaj ib qho tseem ceeb nuance: feem ntau tus kheej-tapping screws tsis tho lawv lub qhov. Lawv kais xov rau hauv ib lub qhov uas twb muaj lawm - ib tug pre-drilled pilot lub qhov, ib tug punched lub qhov, los yog ib lub qhov uas tshuav los ntawm tus ntsia hlau tus taw tes taw qhia nkag mus rau cov khoom muag muag.
Lub ntsiab lus tseem ceeb vim tias cov neeg yuav khoom sib xyaw peb yam khoom sib txawv:
- Self txiav screws (xov-txiav) - muaj ib tug txiav ntug los yog flutes uas tshem tawm cov khoom thiab txiav ib tug xov. Siv ntoo, yas thiab qee yam hlau.
- Xov-forming screws - tshem tawm los yog yob cov khoom es tsis txhob txiav nws, tsim kom muaj cov xov muaj zog uas tsis muaj cov khib nyiab pov tseg. Feem ntau nyob rau hauv cov yas thiab lub teeb hlau.
- Self-drilling screws (Tek screws) - nqa ib lub ntsiab lus tho uas xyaum nws tus kheej lub qhov tsav thiab tom qab ntawd kais xov hauv ib qho haujlwm. Tsis muaj pre-drilling nyob rau hauv cov ntaub ntawv nyias.
Txhua tus kheej-drilling ntsia hlau kuj yog tus kheej-tapping nyob rau hauv lub siab hais tias nws tsim threads - tab sis ib tug self-tapping ntsia hlau tsis muaj ib tug laum taw tes yuav tsis ua rau nws tus kheej lub qhov nyob rau hauv cov ntaub ntawv nyuaj.

Thaum Koj Yuav Tsum Ua Ntej Drill
Pre-drilling (ua lub qhov pilot) yog txoj cai hu nyob rau hauv feem ntau cov ntaub ntawv nyuaj los yog brittle:
- Hlau, stainless thiab tuab aluminium - tus kheej tapping screws tsis tuaj yeem ntseeg tau pib lawv lub qhov hauv cov hlau tuab dua li ob peb millimeters. Yog tsis muaj lub qhov pilot koj yuav raug ib tug tawg, stripped threads los yog ib tug daig ntsia hlau.
- Hardwood thiab ntoo ze ntawm ntug - Cov ntoo tawv tawv tuaj yeem sib cais raws li qhov sib dhos quab yuam ntawm cov ntsia hlau. Ib qhov chaw tsav tsheb nyob ze ntawm qhov kawg lossis ntug ntawm lub rooj tsavxwm yuav luag txhua zaus pom zoo.
- Plastics thiab composites - brittle plastics tawg thiab ntxhov siab-dawb yooj yim. Ib lub qhov pilot muab cov xov chav rau daim ntawv yam tsis muaj kev sib cais.
- Nyias daim hlau (thaum tsis siv tus kheej tho) - lub qhov pre-punched los yog pre-drilled qhov tiv thaiv distortion thiab cia cov xov tuav tusyees.
Tshaj li kev tiv thaiv kev puas tsuaj, tus tsav lub qhov tseem teeb tsa cov ntsia hlau rau ntawm txoj hauv kev ncaj, txo kev tsav lub zog, thiab ua kom cov ntsia hlau sib dhos - uas yog vim li cas cov kws tshaj lij sib dhos ua ntej tho txawm qhov twg tsis yog qhov tsim nyog.
Thaum Koj tuaj yeem hla Pre-Drilling
Muaj peb qhov xwm txheej uas tsis xav tau qhov kev tsav dav hlau:
- Softwood thiab drywall - tus kheej tapping screws tsav ncaj qha mus rau hauv cov ntoo thuv mos, spruce thiab drywall studs yam tsis muaj pre-drilling. Cov ntoo fibers muab txoj hauv kev thiab tsim cov xov nruj.
- Nyias daim hlau nrog tus kheej-drilling screws - Tek ntsia hlau nrog rau qhov kev xyaum ua kom zoo tsim ob lub qhov thiab xov hauv ib kauj ruam, txuag lub sijhawm hauv kev ua haujlwm hlau-rau-hlau.
- Cov yas tsim rau tus kheej tapping nrog tus thawj coj kom zoo - molded-in pilot qhov lossis tshwj xeeb qis-tsav-torque tsim tso cai rau cov xov-ua cov ntsia hlau mus rau hauv yam tsis muaj kev sib cais.
Txoj cai ntawm tus ntiv tes xoo: yog tias cov khoom tuaj yeem deform elastically nyob ib ncig ntawm cov ntsia hlau thiab tuav nws, koj tuaj yeem hla lub laum; Yog hais tias cov khoom yog tawv, nkig los yog load-bearing, pre-drill.
Yuav ua li cas kom loj ib lub qhov Pilot kom raug
Yog tias koj ua qhov kev xyaum ua ntej, qhov luaj li cas yog qhov tseem ceeb. Lub qhov pilot uas me dhau ua rau muaj kev tsav tsheb loj - pheej hmoo rau lub taub hau kev puas tsuaj, tsav tsheb me ntsis cam-tawm, lossis cov khoom tawg. Ib lub qhov loj heev txo cov xov kev sib koom tes thiab rub tawm lub zog, tso cai rau cov ntsia hlau kom loosen hauv qab vibration.
Cov ntsiab lus pib siv tau:
- Xov-forming screws: pilot qhov feem ntau 85-95% ntawm cov ntsia hlau loj (sab nraud) txoj kab uas hla;
- Self-txiav screws: pilot qhov feem ntau nyob ib ncig ntawm 70-85% ntawm txoj kab uas hla loj, txij li cov xov txiav tshem tawm qee yam khoom;
- Ntoo tawv: yuam kev mus rau qhov kawg loj ntawm qhov ntau los txo qhov kev pheej hmoo ntawm kev tawg;
- Soft plastics: yuam kev mus rau qhov kawg me kom cov xov muaj cov khoom txaus los tuav.
Rau feem ntau txoj haujlwm, cov tuam txhab ntsia hlau luam tawm cov lus pom zoo ntawm qhov chaw hauv cov ntaub ntawv - thaum muaj kev tsis ntseeg, ua raws li lub rooj lossis kev sim ntawm cov khoom seem ua ntej.
Feem ntau yuam kev kom zam
- Hla tus tsav hauv hardwood - feem ntau ua rau cov boards sib cais thiab stripped threads;
- Oversizing lub qhov pilot - lub qhov "siab dav" ntsiag to rhuav tshem lub zog rub tawm;
- Siv tus kheej tapping ntsia hlau qhov twg yuav tsum tau ib tug self-drilling ntsia hlau - tawv steel ua haujlwm yam tsis muaj qhov tho qhov xaus ntawm cov khoom tawg;
- Tsav tsheb nrawm dhau - tshav kub thiab torque buildup soften plastics thiab gall threads nyob rau hauv hlau;
- Sib tov txiav thiab sib sau hom -Txhua tus muaj nws tus kheej txoj cai pilot-qhov sizing.
