Raws li hom hollow fastener, tubular rivets tau siv dav hauv cov haujlwm xws li lub nra, rooj tog zaum, thiab kev tsim tsheb. Lawv ua haujlwm los ntawm kev nthuav tawm lub cev rivet nyob rau hauv nruj kom ruaj ntseg koom nrog ob lossis ntau daim ntawv ntawm cov khoom; cov txheej txheem yog yooj yim thiab yuav tsum tsis muaj drilling los yog vuam. Txij li cov kev xav tau tshwj xeeb sib txawv heev nyob ntawm daim ntawv thov, kev nkag siab cov ntsiab lus tseem ceeb yog qhov tseem ceeb rau kev xaiv txoj cai rivet.
Key Specification Parameters rau Tubular Rivets
Tubular rivet specifications feem ntau txhais los ntawm cov tsis xws li txoj kab uas hla, ntev, khoom, thiab lub taub hau hom, raws li cov lus qhia hauv qab no:
1. Txoj kab uas hla (D)
Qhov no yog hais txog sab nraud ntawm lub cev rivet, feem ntau ntawm 2mm txog 12mm (saib rau * Rivet Technical Specifications, 2024 Edition*). Cov kab me me yog tsim rau kev sib koom ua ke ntawm cov ntawv nyias nyias, thaum cov kab uas loj dua muaj peev xwm ntau dua -cov kabmob, ua rau lawv zoo tagnrho rau cov ntawv tuab lossis siab - daim ntawv thov. Piv txwv xws li: Φ2-5mm rau lub nra, Φ4-8mm rau rooj tog, thiab Φ5-10mm rau cov khoom siv tsheb.
2. Ntev (L)
Qhov no suav nrog ob lub cev ntev thiab lub taub hau qhov siab, nrog rau qhov ntev tag nrho ntawm 5mm txog 30mm. Kev xaiv nyob ntawm tag nrho cov tuab ntawm cov nplooj ntawv tau koom nrog; Nws raug pom zoo tias lub cev ntev tshaj li tag nrho cov ntawv tuab los ntawm 2-5mm kom tso cai rau qhov chaw nthuav dav. Piv txwv li, thaum koom nrog ob 3 hli - cov ntawv tuab, 8 hli ntev (5 hli lub cev + 3 hli taub hau) yuav raug xaiv.
3. Khoom siv
Cov ntaub ntawv muaj xws li qis- carbon steel (hlau), stainless hlau (304/316), thiab aluminium alloy. Tsawg- carbon steel yog tus nqi- siv tau thiab tsim nyog rau lub nra thiab rooj tog zaum; stainless hlau muaj corrosion kuj, ua rau nws zoo tagnrho rau cov khoom siv sab nraum zoov; aluminium alloy yog lub teeb yuag thiab nquag siv hauv aerospace thiab cov khoom siv hluav taws xob.
4. Hom Lub taub hau
Cov hom muaj xws li semi- round (round) taub hau, countersunk (flush) taub hau, thiab yias taub hau. Semi- lub taub hau puag ncig yog qhov zoo nkauj thiab tsim nyog rau cov ntawv thov raug pom; countersunk taub hau zaum flush, ntsib cov kev xav tau rau qhov chaw du (xws li, rooj tog zaum sab hauv); yias taub hau yog siv dav tshaj plaws, muab qhov sib npaug ntawm lub zog thiab qhov tsos.
Pom zoo Specifications rau ntau yam xwm txheej
Cov kev xav tau rau tubular rivet specifications sib txawv heev nyob rau hauv kev lag luam; Cov hauv qab no yog cov kev pom zoo rau cov xwm txheej ntawm daim ntawv thov:
1. Lub nra thiab lub hnab ntim khoom lag luam
Cov rivets me me feem ntau yog siv, nrog txoj kab uas hla ntawm 2-5 mm thiab ntev ntawm 5-15 mm; cov ntaub ntawv feem ntau yog hlau lossis aluminium alloy. Piv txwv li, hlau rivets nrog lub taub hau puag ncig (Φ3 mm × L8 mm) feem ntau siv los txuas cov tes rau 20-nti trolley rooj plaub.
2. Kev tsim khoom vaj khoom tsev
Yuav tsum muaj qhov sib npaug ntawm lub zog thiab kev zoo nkauj; Txoj kab uas hla ntawm 4-8 mm thiab ntev ntawm 10-25 mm. Rau cov vaj huam sib luag tuab dua 5 hli, stainless hlau yog cov khoom nyiam (piv txwv li, Φ6 mm × L15 mm 304 stainless hlau countersunk rivets).
3. Automotive qhov chaw
Txoj kab uas hla ntawm 5-10 mm thiab ntev ntawm 15-30 mm; cov ntaub ntawv muaj xws li siab -lub zog steel lossis 304 stainless hlau. Piv txwv li, stainless hlau tubular rivets (Φ6 mm × L20 mm) feem ntau yog siv los ruaj ntseg sab hauv qhov rooj panels.
Kev xaiv xaiv
Kev xaiv yuav tsum yog raws li qhov yuav tsum tau ua los tiv thaiv kev ua tsis tiav riveting:
1. Vaj huam sib luag Thickness Matching: Lub rivet lub cev ntev yuav tsum tshaj tag nrho cov khoom thickness los ntawm 2-5 hli kom paub meej tias qhov sib txawv yog sau tom qab nthuav.
2. Material Compatibility: Thaum koom nrog cov khoom sib txawv, xav txog coefficients ntawm thermal expansion; siv cov khoom qub lossis siv galvanized los tiv thaiv- kev kho xeb yog pom zoo.
3. Tool Compatibility: Lub stroke ntawm lub riveting cuab tam yuav tsum phim lub rivet ntev; rivets uas tuab dhau los yog ntev dhau yuav ua rau muaj kev sib koom ua ke tsis ruaj ntseg.
Cov saum toj no qhia txog cov ntsiab lus tseem ceeb thiab kev xaiv rau tubular rivets. Hauv kev siv tswv yim, kev ntsuam xyuas dav dav raws li qhov xwm txheej tshwj xeeb, vaj huam sib luag thickness, thiab cov kev xav kom zoo nkauj yog tsim nyog los xyuas kom meej cov txiaj ntsig zoo riveting.
