Nws yog qhov tsim nyog rau txhua tus neeg kom paub txhua yam txog cov ntsia hlau zoo nkauj, vim tias lawv tsuas yog tso cai rau koj txuas ntau yam khoom lag luam thiab ua tiav qhov muag zoo nkauj. Thaum txiav txim siab seb lawv yog dab tsi, qhov loj npaum li cas thiab lawv lub hom phiaj, koj tuaj yeem tshem tawm ntau qhov ua yuam kev. Nws tseem yuav tsum tau kawm, txawm li cas los xij, qhov zoo thiab qhov tsis zoo ntawm cov ntsia hlau zoo nkauj.

Nws yog dab tsi?

Nws yuav tsum tau hais tam sim ntawd cov ntsia hlau zoo nkauj yuav luag zoo ib yam li cov ntsia hlau zoo ib yam li lwm tus, tab sis lawv muaj ntau qhov sib txawv tseem ceeb. Qhov sib txawv txhawj xeeb:

• xaus qhov kev ua tiav;
• threaded suab;
• kev xyaum

Txhua tus kheej tapping screws yog qhov muaj nqis heev. Yog tsis muaj lawv, nws tsis tuaj yeem tsim lossis kho qee yam.

Cov fasteners zoo yog thawj qhov kev lees paub ntawm kev sib txuas zoo ntawm cov qauv.

Txwv tsis pub, txawm tias cov khoom siv zoo tshaj plaws tsis tuaj yeem lav qhov ua tiav thiab ruaj khov siv cov khoom tiav .… Nws yog qhov khaws nyiaj ntawm cov khawm uas ua rau ntau tus neeg ua tsis tiav.

Cov kws tshaj lij ntawm cov qib zoo nkauj yuav tsum:

• lav kev ruaj khov, kev sib txuas zoo ntawm txhua lub sijhawm;
• yooj yim ua haujlwm ntau li ntau tau;
• tswj kev ua haujlwm siab;
• saib zoo nkauj thiab ntxim nyiam;
• haum rau ntau txoj haujlwm;
• kom ua tiav qhov ruaj khov ntawm cov pob qij txha.

Tus kheej tapping ntsia hlau yog tus pas nrig nrog lub taub hau thiab xov tshwj xeeb … Kev txiav los ntawm sab nraud haum raws nraim hauv sab hauv thiab tsim cov xov sab hauv ntawm lub qhov. Nws tuaj yeem npog cov cylindrical nto ob qho tag nrho lossis ib nrab. Kev sib txuas ntawm ntau qhov chaw rau ib leeg yuav siv qhov chaw ntseeg tau.

Tab sis tib lub sijhawm, tsis zoo li cov ntsia hlau, kev sib txuas ntawm tus kheej tapping screws yog qhov yooj yim dua rau kev sib cais, thiab tsis zoo li cov ntsia hlau, tsis tas yuav xav tau kev ua ntej drilling.

Cov yam ntxwv tuaj yeem pom ntawm qhov piv txwv ntawm cov khoom lag luam zoo nkauj tus kheej tapping ntsia hlau SPAX … Cov khoom no tau ua tiav xov thiab nruab nrog lub taub hau ib nrab-countersunk. Cov lus qhia conical tau ua nyob rau hauv cov duab plaub-tog. Qhov kev tsim no tso cai rau kev sib cais ntawm cov ntoo ntoo yam tsis muaj kev ua ntej drilling. Qhov no tau ua tiav txawm tias muaj qhov nrug me me rau ntawm ntug (tab sis cov ntoo tawv tseem yuav tsum tau xyaum).

Cov xov yog ua nrog txhim kho corrugated profile. Cov qauv no txuas mus txog qhov kawg ntawm cov khoom. Yog li ntawd, nws tuaj yeem ntsia tau sai thiab ntseeg tau. Lub taub hau muaj cov npoo tshwj xeeb milling. Lub taub hau no yaug tawm, thiab ua tsaug rau qhov tshwj xeeb spline, lub cuab yeej tsis plam tawm thaum lub zog loj raug xa mus.

Saib

Qhov sib txawv tseem ceeb ntawm tus kheej tapping screws yog cuam tshuam nrog lawv cov tshuaj lom neeg muaj pes tsawg leeg .… Yog li, hauv cov pa roj carbon, hlau thiab carbon tau sib xyaw ua ke. Tus so ntawm qhov tsis huv yog tsis tuaj kawm ntawv, lossis tam sim no nyob rau qhov txwv tsawg - tsawg dua 1%. Cov hlau no yog cov tshuab muaj zog heev. Cov hlau tsis huv kuj tseem siv dav - qhov no yog hlau, suav nrog txog 10, 5% chromium.

Qhov no ntxiv guarantees corrosion kuj Nyob rau tib lub sijhawm, tag nrho cov khoom siv dag zog ntawm cov khoom lag luam loj hlob. Rau cov txheej txheem kev pabcuam lub neej, cov hlau tsis muaj tus kheej tapping ntsia hlau xyaum tsis tuaj yeem xeb. Tseem ceeb khoom huv huv.

Cov hlau tsis xeb hlau tuaj yeem siv tau txawm tias kho mob thiab khoom siv hauv chav ua noj, rau sib piv cov rooj tog zaum

Hauv qee kis, cov khoom siv kho kom zoo nkauj yog tsim los ntawm tooj dag.

Countersunk lub taub hau tsim txhais tau hais tias thaum sib tw nws tau raus kiag li hauv cov khoom siv los ua ke … Hom semi-countersunk yog qhov txawv los ntawm qhov ua tau zoo ntawm "pas nrig-xov" interface. Nws cov qauv tsim tso cai rau kev nce siab sib tw. Txawm li cas los xij, kev tsim ib nrab ib ncig pab tsim kom muaj kev sib cuag thiab nce kev ruaj ntseg ntawm txoj hlua.

Kuj tseem muaj tus kheej tapping screws nrog:

• semicircular hau nrog lub tshuab ntxhua khaub ncaws;
• truncated-conical "flea";
• hex taub hau;
• lub tog raj kheej;
• tsis tshua muaj, nruab nrab lossis feem ntau kos duab.

Cov ntawv thov

Cov ntsia hlau zoo nkauj, zoo li cov ntsia hlau zoo tib yam, tuaj yeem siv rau:

• tso cov khoom vov tsev;
• koom nrog cov vaj huam sib luag nyuaj;
• txuas ntawm cov ntawv hlau;
• sib dhos ntawm cov khoom siv rooj tog.

Daim ntawv thov nyob ntawm qhov kev pab them nqi.

Yog li, tus kheej tapping screws ua kom tsis muaj txheej tsuas tuaj yeem siv hauv chav qhuav.

Oxidized fasteners zoo kawg nkaus zam qhov hnyav, tab sis tseem muaj kev sib cuag tsis zoo nrog kua. Qauv phosphated txoj kev, tab sis tiv taus dej nkag mus. Galvanized tus kheej tapping screws feem ntau tsim los rau kev ua kom muaj huab cua huv.
