DIN7991 Dub Hex Socket Countersunk Lub Taub Hau Taub Hau Bolt
Dab tsi yog hex socket countersunk taub hau ntsia liaj qhov rooj?
Countersunk bolts yog tiaj taub hau ntsia liaj qhov rooj fasteners nrog hex socket tsav rau hauv lub taub hau.Countersunk bolts muaj lub khob hliav qab hom caj dab nrog lub taub hau tiaj tus, lub taub hau tiaj tus hex socket bolts, lub taub hau lub taub hau lub taub hau yog lwm lub npe ntawm hex taub hau bolts.Countersunk bolts qhov ntev yog txhais nyob rau hauv ob qho tib si metric thiab imperials ntau thiab tsawg nrog unified lub teb chaws coarse suab (UNC), nplua suab (UNF), taag suab (UN) thiab ISO metric xov profile.Cov no yog tsim nyob rau hauv tag nrho cov khoom siv thiab ASTM specifications tab sis feem ntau yog tsim nyob rau hauv F568 qib 8.8, 10.9,12.9, F593, BS, EN, ISO3506-1, SS304, SS316,2205, thiab lwm yam.
Daim ntawv thov
Nyob rau saum npoo ntawm lub qhov txuas ntawm qhov txuas, lub qhov (socket) 90-degree conical puag ncig yog ua tiav, thiab lub taub hau ntawm lub tshuab tiaj tus ntsia hlau yog nyob rau hauv lub qhov (socket) puag ncig, uas yog flush nrog rau saum npoo ntawm cov khoom sib txuas.Lub tshuab tiaj tus ntsia hlau kuj tseem siv tau rau qee lub sijhawm nrog lub taub hau puag ncig lub taub hau tiaj tus ntsia hlau.Hom ntsia hlau no zoo nkauj dua thiab siv rau hauv qhov chaw uas qhov chaw tuaj yeem tso cai rau me ntsis protrusion.
Feem ntau hex socket countersunk taub hau bolts yog siv nyob rau hauv qhov chaw uas qhov chaw ntawm qhov chaw tsis tuaj yeem tsa tom qab kev teeb tsa.Muaj ob hom ntawm qhov yuav tsum tau fastened.Lub thickness ntawm lub taub hau, tom qab cov ntsia hlau yog nruj, ib feem ntawm cov ntsia hlau xov tseem tsis nkag mus rau lub threaded qhov.Nyob rau hauv cov ntaub ntawv no, lub countersunk taub hau ntsia hlau tuaj yeem nruj nreem.
Lub khob hliav qab ntawm lub taub hau countersunk taub hau ntsia hlau muaj 90 ° lub khob hliav qab.Feem ntau, lub apex lub kaum sab xis ntawm ib qho kev xyaum ua khoom tshiab yog 118 ° -120 °.Qee tus neeg ua haujlwm tsis tau kawm tsis paub qhov txawv ntawm lub kaum sab xis no, thiab feem ntau siv 120 ° laum Reaming, uas ua rau lub taub hau ntawm lub taub hau tsis strained thaum tuav lub taub hau taub hau, tab sis ib txoj kab hauv qab ntawm lub taub hau ntsia hlau, uas yog. ib qho ntawm cov laj thawj yog vim li cas thiaj li hu ua hex socket countersunk head cap bolts tsis tuaj yeem tuav nruj.
Kev ceev faj thaum siv
1.Lub taper ntawm lub qhov reaming yuav tsum yog 90 °.Los lav nws, nws yog qhov zoo dua kom tsawg dua 90 °, tsis ntau tshaj 90 °.Qhov no yog ib qho tseem ceeb ua kom yuam kev.
2.Yog hais tias lub thickness ntawm cov ntawv hlau yog tsawg tshaj li lub thickness ntawm lub taub hau ntawm lub countersunk taub hau ntsia hlau, koj muaj peev xwm hloov lub me me ntsia hlau, los yog es nthuav lub qhov me dua nthuav lub qhov kom lub cheeb ntawm lub hauv qab lub qhov yuav loj dua. thiab qhov tsis nruj.
3. Yog hais tias muaj ntau yam hex qhov (socket) countersunk head cap bolt qhov ntawm qhov, ua kom meej meej thaum lub sij hawm machining.Thaum lub laum yog crooked, nws yog ib qho nyuaj rau pom lub rooj sib txoos, tab sis nws yuav tsum nruj raws li ntev raws li qhov kev ua yuam kev me me, vim hais tias thaum lub ntsia hlau tsis nruj heev loj (txog li 8 hli), thaum muaj kev ua yuam kev. qhov deb ntawm lub qhov, lub taub hau ntsia hlau yuav deformed vim yog quab yuam thaum nruj, los yog nws yuav nruj.
