Yuav siv cov bolts li casSiv
Cov qauv rau cov bolts nruj no suav nrog cov hauv qab no:
1. Cov lus qhia tshwj xeeb: Cov xov diameters feem ntau suav nrog M1.6, M2, M2.5, M3, M4, M5, M6, M8, M10, M12, M16, M18, M20, thiab lwm yam; Feem ntau cov ntsia hlau ntev muaj xws li 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 16, 18, 20, 25, 30, 35, 40, 45, 50, 60, thiab lwm yam.
2. Cov khoom siv: xws li hlau alloy, carbon steel, stainless hlau, yas, tooj liab, thiab lwm yam.
3. Cov qauv: xws li GB 77-2000, ISO 4026-2003, ANSI/ASME B18.2.1, thiab lwm yam.
Tightening bolts nrog cov duab sib txawv kawg yog tsim rau ntau zaus:
Hexagonal tiaj tus kawg teeb ntsia hlau (DIN 913): Qhov chaw tiv toj yog tiaj tus thiab tsis ua kom lub ntsej muag tom qab zawm. Nws yog haum rau cov tawv tawv los yog qhov chaw uas feem ntau xav tau kev hloov kho.
Hexagonal cone kawg teeb ntsia hlau (DIN 914): Nws yog qhov tsim nyog rau kev siv ntawm qhov chaw nrog qis hardness los ntawm kev siv nws lub khob ntse ntse los nias tawm tsam qhov chaw sib cuag.
Sab hauv hexagon concave kawg teeb ntsia hlau (DIN 916): Qhov kawg yog concave, feem ntau yog siv los kho qhov kawg ncej, thiab sab saum toj nruj yog feem ntau cylindrical, haum rau qhov chaw uas muaj siab hardness.
Sab hauv hexagon convex kawg zawm ntsia hlau (DIN 915): Nws qhov kev siv tshwj xeeb yog nyob ntawm qhov xav tau tiag tiag.
Cov kev qhia tshwj xeeb ntawm kev zawm bolts feem ntau suav nrog txoj kab uas hla, qhov ntev, lub suab, qhov kawg zoo, thiab cov khoom siv ntawm lub ntsia liaj qhov rooj. Cov kev qhia tshwj xeeb no yuav cuam tshuam rau lawv daim ntawv thov, raws li qhia hauv qab no:
1. Txoj kab uas hla: Qhov loj ntawm txoj kab uas hla ntawm lub ntsia liaj qhov rooj, qhov muaj zog ntawm nws lub peev xwm load-bearing yog feem ntau. Nyob rau hauv cov xwm txheej uas loj loads yuav tsum tau yug los, xws li nyob rau hauv loj mechanical lug, loj txoj kab uas hla fastening bolts yog siv; Hauv cov khoom siv nrog cov khoom me me, siv txoj kab uas hla me dua fastening bolts tuaj yeem ua tau raws li qhov yuav tsum tau ua.
2. Length: Qhov ntev txiav txim siab qhov tob uas lub ntsia liaj qhov rooj tuaj yeem nkag mus rau hauv cov khoom raug fastened. Cov bolts ntev tuaj yeem muab kev ruaj ntseg zoo dua thiab ruaj khov, tab sis nyob rau hauv qhov chaw tsawg, nws yuav tsim nyog xaiv cov bolts luv dua.
3. Pitch: Tightening bolts nrog lub suab me me muaj qhov ua tau zoo ntawm kev ntsuas tus kheej thiab tsim nyog rau cov xwm txheej uas tsis tshua muaj kev vibration thiab tsis tas yuav tsum tau hloov kho; Bolts nrog lub suab loj dua muaj cov ntsia hlau nrawm nrawm thiab tsim nyog rau qhov chaw uas xav tau kev teeb tsa sai lossis hloov kho tsis tu ncua.
4. Cov duab kawg: Cov duab kawg sib txawv muaj cov haujlwm sib txawv thiab daim ntawv thov scenarios. Piv txwv li, lub tiaj tus kawg fastening bolts muaj kev puas tsuaj tsawg heev rau qhov chaw sib cuag thaum lub sij hawm nruj, thiab feem ntau yog siv nyob rau hauv cov xwm txheej uas qhov hardness yog siab los yog deg kev ncaj ncees; Cone kawg zawm bolts tau zoo embed cov khoom fastened thiab haum rau cov ntaub ntawv nrog qis hardness; Concave kawg zawm bolts yog tsim rau kho cylindrical nto xws li ncej xaus; Lub convex kawg zawm bolt tuaj yeem siv tau yooj yim raws li cov xwm txheej tshwj xeeb.
5. Khoom siv: Cov khoom siv txiav txim siab lub zog, tiv thaiv corrosion, thiab hnav tsis kam ntawm lub ntsia liaj qhov rooj. Nyob rau hauv ib puag ncig hnyav xws li kub thiab corrosion, nws yog ib qho tsim nyog yuav tau xaiv cov khoom siv nrog cov khoom siv sib xws, xws li cov hlau tsis muaj steel lossis cov khoom siv kub kub rau kev zawm bolts.
1. Rau cov kev sib txuas dav dav dav hlau
2. Lub tshuab ntxhua khaub ncaws yuav tsum muab tso rau ntawm lub taub hau taub hau thiab lub txiv ntseej sab, thiab feem ntau yuav tsum tsis pub ntau tshaj 2 lub tshuab ntxhua khaub ncaws tso rau ntawm lub taub hau taub hau, thiab feem ntau yuav tsum tsis pub ntau tshaj 1 lub tshuab ntxhua khaub ncaws. .
3. Rau cov bolts thiab thauj tog rau nkoj bolts tsim los tiv thaiv kev xoob, cov txiv ntoo lossis lub caij nplooj ntoos hlav ntxhua khaub ncaws yuav tsum tau siv, thiab lub caij nplooj ntoos hlav ntxhua khaub ncaws yuav tsum tau muab tso rau ntawm cov txiv ntoo.
4. Rau cov ntsia liaj qhov rooj sib txuas bearing dynamic loads los yog qhov tseem ceeb, lub caij nplooj ntoos hlav ntxhua khaub ncaws yuav tsum tau muab tso rau raws li tus tsim yuav tsum tau, thiab lub caij nplooj ntoos hlav washers yuav tsum tau teem nyob rau sab ntawm lub txiv ntoo.
5. Rau I-beams thiab channel steels, inclined washers yuav tsum tau siv thaum siv inclined dav hlau sib txuas ua rau cov kabmob nto ntawm cov txiv ntseej thiab lub taub hau ntsia hlau perpendicular rau cov ntsia hlau.
