Kev siv:
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. Cov ntsia hlau zoo li no zoo nkauj dua thiab siv rau hauv qhov chaw uas qhov chaw tuaj yeem tso cai rau me ntsis protrusion.
Yuav siv li cas?
Feem ntau cov countersunk screws yog siv rau hauv qhov chaw uas qhov chaw ntawm qhov 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 zawm lub taub hau countersunk, tab sis ib txoj kab hauv qab ntawm lub taub hau ntsia hlau, uas yog. ib qho ntawm cov laj thawj vim li cas thiaj li hu ua countersunk screws 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 countersunk ntsia hlau qhov nyob rau hauv ib feem, 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.
Khoom zoo:

☆ Ntsuas thiab txheej txheem siv cov cuab yeej siv tshuab precision thiab ntsuas cov cuab yeej raws li kev tswj hwm ib puag ncig nruj me ntsis.
- High quality carbon steel (35 # / 45 #)
☆ Nrog lub neej ntev, tsis muaj cua sov tiam, siab hardness, siab rigidity, tsis tshua muaj suab nrov, siab hnav tsis kam thiab lwm yam ntxwv.
- Nqi-zoo
☆ Kev siv cov pa roj carbon zoo steel hlau, tom qab kev ua tiav thiab kev tsim, txhim kho cov neeg siv kev paub zoo heev.
Kev kho deg:
- BLACK
☆ Dub yog ib txoj hauv kev zoo rau kev kho cua sov. Lub hauv paus ntsiab lus yog ua kom muaj oxide zaj duab xis ntawm cov hlau saum npoo kom cais cov huab cua thiab ua tiav kev tiv thaiv xeb. Blackening yog ib txoj hauv kev zoo rau kev kho cua sov hlau. Lub hauv paus ntsiab lus yog ua kom muaj oxide zaj duab xis ntawm cov hlau saum npoo kom cais cov huab cua thiab ua tiav kev tiv thaiv xeb.
- ZINC
☆ Electro-galvanizing yog ib txwm siv hlau txheej hlau siv tshuab uas muab cov corrosion tsis kam rau cov hlau chaw. Lub ntsiab zoo yog zoo solderability thiab haum tiv thaiv. Vim nws cov khoom zoo lubrication, cadmium plating feem ntau yog siv hauv aviation, aerospace, marine, thiab xov tooj cua thiab khoom siv hluav taws xob. Cov txheej plating tiv thaiv cov hlau substrate los ntawm ob qho tib si thiab tshuaj tiv thaiv, yog li nws cov corrosion kuj zoo dua li zinc plating.
- HDG
☆ Lub ntsiab zoo yog zoo solderability thiab haum tiv thaiv. Vim nws cov khoom zoo lubrication, cadmium plating feem ntau yog siv hauv aviation, aerospace, marine, thiab xov tooj cua thiab khoom siv hluav taws xob. Cov txheej plating tiv thaiv cov hlau substrate los ntawm ob qho tib si thiab tshuaj tiv thaiv, yog li nws cov corrosion kuj zoo dua li zinc plating. Kub-dip zinc muaj kev tiv thaiv corrosion zoo, kev tiv thaiv kev txi rau steel substrates, huab cua tsis kam, thiab tiv thaiv dej ntsev yaig. Nws yog tsim rau cov nroj tsuag tshuaj, refineries thiab ntug hiav txwv dej thiab offshore operating platforms.
