Tus kheej -Tapping Screws Tus yam ntxwv thiab cov ntsiab lus tseem ceeb

Tus kheej -tapping screws yog dav siv fasteners rau txuas cov ntawv hlau, cov khoom yas, thiab cov khoom sib xyaw. Lawv cov qauv tsim thiab kev ua tau zoo ncaj qha txiav txim siab kev sib dhos zoo thiab kev sib txuas kev ntseeg tau. Hauv kev tsim khoom niaj hnub no, tus kheej -tapping fasteners tau tsim rau ntau hom, suav nrog xov- txiav cov ntsia hlau, xov- ua cov ntsia hlau, tus kheej- tho screws, tapping fasteners, thiab tus kheej-tapping xov- ua cov rau tes. Lawv ua lub luag haujlwm tseem ceeb hauv kev sib dhos ntawm cov khoom siv hauv tsev, tsheb, cov khoom siv hluav taws xob tshiab, thiab cov khoom siv hluav taws xob.

Txhua tus kheej -tapping ntsia hlau muaj lub taub hau, lub taub hau, thiab lub taub hau. Nws cov qauv tsim feem ntau suav nrog plaub yam tseem ceeb: lub taub hau zoo, txoj kev nruj, xov hom, thiab daim ntawv qhia.

1. Lub taub hau zoo

Cov hom muaj xws li round, oval, pan, countersunk, countersunk, hexagonal, hexagonal flange, thiab washer-flange hau. Cov duab sib txawv ntawm lub taub hau sib txawv raws li cov kev cai sib dhos sib txawv. Piv txwv li, lub lauj kaub taub hau yog tsim rau cov ntaub ntawv nyias nyias, thaum hexagonal flanges feem ntau siv los tiv thaiv lub zog siab dua.

2. Hom Torque

Hom torque txiav txim siab qhov sib xws ntawm cov cuab yeej sib dhos thiab cov ntsia hlau. Muaj ob hom tseem ceeb: sab nraud torque (xws li hexagonal thiab torus) thiab sab hauv torque (xws li Phillips, slotted, thiab hexagon socket). Sab nraud torque tuaj yeem tiv taus lub zog siab dua thiab haum rau siab - lub zog screws xws li tus kheej - tho thiab tus kheej - txiav cov ntsia hlau thiab tus kheej - koom nrog drilling screws rau tapping.

3. Xov hom

Hom xov ncaj qha cuam tshuam rau tus kheej -tapping kev ua tau zoo thiab cov khoom sib xws. Hom threads uas muaj xws li:

Tus kheej-tapping threads (wide pitch threads): siv rau cov hlau los yog tawv substrates;

Tshuab threads (tus qauv xov): siv rau ua ntej -taped qhov los yog siab-precision los ua ke;

Drywall ntsia hlau threads thiab fiberboard xov: siv rau ntawm ntoo los yog yas substrates;

Ntau- cov xov hlau lead (ib zaug, ob npaug, thiab ntau- pib) yog siv los txhim kho kev ua haujlwm ntawm screwing.

Xov- ua cov ntsia hlau thiab xov- txiav cov ntsia hlau yog ob feem ntau siv rau pem hauv ntej- xov xov kawg hom hauv kev lag luam. Cov yav dhau los ua cov xov sab hauv los ntawm kev tsim cov yas, thaum cov ntawv tom kawg ua tus kheej -tapping qhov los ntawm kev txiav.

4. Hom kawg

Qhov xaus feem ntau muaj nyob rau hauv ob hom: tapered thiab flat. Nyob ntawm daim ntawv thov, lub tapered los yog tiaj tus kawg yuav machined nrog txiav grooves, grooves, los yog laum -zoo li tus nta los txhim kho drilling thiab tapping peev xwm. Cov qauv tsim no feem ntau pom muaj nyob hauv cov qauv xws li tus kheej- ua qhov drilling thiab tapping screws thiab tus kheej -tapping xov- ua rau tes, ua kom muaj txiaj ntsig zoo "ib- kauj ruam qhov tsim thiab tus kheej-tapping" sib dhos.

Tus kheej -drilling screws feem ntau yog ua los ntawm cov hlau carburized, uas suav rau feem ntau ntawm kev tsim khoom. Stainless hlau lossis tooj liab alloys yog siv rau hauv qee qhov kev thov. Txhawm rau kom muaj zog thiab toughness, cov ntsia hlau yuav tsum tau kho cua sov:

Carbon steel screws yuav tsum tau carburizing los yog quenching kom nce hardness;

Stainless hlau screws xav tau kev daws hardening los txhim kho xov lub zog thiab corrosion kuj.

Lub tshav kub- kho cov qauv yuav tsum ua kom tiav cov yam ntxwv ntawm "nyuaj rau sab nraud, tawv rau sab hauv": siab tawv hardness kom nws tus kheej- tho rau hauv lub substrate, thaum lub hauv paus tawv tiv thaiv kev puas tsuaj. Cov yam ntxwv no tshwj xeeb yog qhov tseem ceeb rau tapping fasteners thiab tus kheej -drilling screws.

Txhawm rau tiv thaiv corrosion thiab txhim kho cov tsos, tus kheej -drilling screws feem ntau siv ntau yam txheej txheem tiv thaiv nto:

Electroplating nrog zinc, npib tsib xee, lossis tin: Txhim kho xeb tiv thaiv;

Phosphating:Feem ntau siv rau ntawm cov ntsia hlau phab ntsa thiab cov khoom siv los txhim kho adhesion;

Txheej:Tus kheej-drilling screws siv nyob rau hauv ib puag ncig hnyav feem ntau siv cov txheej txheem sib xyaw los txhim kho cov tshuaj tsuag ntsev.

Tus kheej-drilling screws feem ntau yog tsim los siv lub taub hau txias, siv lub siab -ceev txias taub hau tshuab thiab planetary xov dov tshuab. High- cov khoom siv ceev ua kom lub taub hau tag nrho cov ntsia hlau thiab cov xov hlau raug, yog li txhim kho tag nrho cov khoom sib xws thiab tus kheej- tho kev ua haujlwm. Rau kev ua haujlwm ntawm tus kheej-drilling thiab tus kheej- txiav screws, cov txheej txheem tsim khoom yuav tsum muaj kev tswj xyuas meej ntawm cov laum taub symmetry thiab txiav lub kaum ntse ntse kom ruaj khov kev sib xyaw drilling thiab tapping.

Nrog rau kev nce qib ntawm lub teeb yuag, automation, thiab kev tsim khoom ntse, cov qauv thiab kev ua haujlwm ntawm tus kheej -drilling screws txuas ntxiv nthuav dav. Los ntawm kev sib sau ua ke ntawm cov ntawv hlau, nws tau maj mam nthuav mus rau kev sib dhos ntawm lub zog tshiab lub tsheb roj teeb pob, cov khoom siv hauv tsev ntawv hlau, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob. Nyob rau hauv lub neej yav tom ntej, tus kheej- koom nrog drilling screws rau tapping thiab xov- ua cov ntsia hlau yuav ua lub luag haujlwm ntau dua hauv cov tshuab sib dhos, ua kom muaj kev sib txuas zoo uas tshem tawm ua ntej -drilling thiab tapping qhov yuav tsum tau ua thiab pab ua ib qho - kauj ruam ua.

Tus kheej-tapping ntsia hlau tshuab yog lub hauv paus tseem ceeb ntawm cov tshuab fastening niaj hnub. Los ntawm xov- txiav screws rautus kheej- tho screws, thiab los ntawm cov txheej txheem ib txwm muaj rau siab -kawg precision hluav taws xob sib dhos, kev nce qib hauv cov txheej txheem tsim khoom thiab cov ntaub ntawv tshawb fawb tau ua rau muaj kev ua tau zoo dua, muaj zog dua, thiab ntau dua automation, ua rau cov fasteners indispensable core Cheebtsam rau kev tsim ntse thiab kev sib dhos zoo.
