Lub rivet shank yog lub hauv paus ntawm txhua qhov rivet. Txhua lub rivet, txawm tias khov kho, dig muag, semi-tubular lossis structural ring-grooved, yog tsim nyob ib puag ncig lub shank ntxiv rau cov rivet sib txuas uas ua tiav cov haujlwm clamping thiab xauv.
1.1 Rivet Shank: Lub Cev Nqa Khoom Nruab Nrab
Lub rivet shank yog hais txog lub cylindrical tseem ceeb uas hla dhau cov qhov uas tau drilled ua ntej ntawm cov khoom ua haujlwm sib dhos, kev tuav shear, tension thiab kev co kev ntxhov siab thoob plaws lub neej ua haujlwm ntawm qhov sib koom ua ke. Nws peb lub hauv paus ntsiab lus ncaj qha txiav txim siab qhov ua tau zoo ntawm rivet:
Txoj Kab Uas Hlais: Qhov loj me ntawm tus qauv yog txij li 2.4 hli mus txog 12 hli rau kev siv hauv kev lag luam. Cov kab uas tsis loj txaus ua rau muaj qhov xoob thiab tsis muaj zog clamping.
Qhov Ntev Ntawm Qhov Tuav (Qhov Ntev Ntawm Qhov Tuav): Qhov seem uas siv tau ntawm qhov tuav uas haum rau tag nrho cov tuab ntawm cov khoom sib koom ua ke. Kev xaiv qhov tuav uas tsis txaus yuav ua rau lub qhov tom qab puv nkaus; kev tuav ntau dhau ua rau tsis sib npaug thiab kev sib txuas xoob thaum lub sijhawm thauj khoom.
Cov Khoom Siv Shank & Txheej: Cov khoom siv raw feem ntau suav nrog txhuas alloy, carbon steel, 304/316 stainless hlau, tooj liab thiab tooj dag. Zinc plating, galvanization lossis passivation coatings yog siv rau ntawm qhov chaw shank kom thaiv oxidation thiab galvanic corrosion ntawm cov hlau sib txawv.
1.2 Cov Khoom Siv Rivet Txhawb Nqa Tseem Ceeb Ua Ke Nrog Lub Shank
1.2.1 Lub Taub Hau Rivet
Lub taub hau muab qhov chaw dav dav rau kev nqa kom faib lub zog clamping sib npaug thoob plaws ntawm qhov chaw ntawm lub vaj huam sib luag pem hauv ntej, tiv thaiv kev rub los ntawm kev ntxhov siab. Cov qauv taub hau txheem kev lag luam suav nrog:
- Lub taub hau dome: Kev sib dhos dav dav, thaj chaw sib cuag loj tshaj plaws, siv dav rau cov txee hlau thiab cov thav duab khoom siv
- Lub taub hau loj flange dav: Rau cov substrates nyias, brittle xws li cov ntawv yas thiab cov vaj huam sib luag txhuas composite
- Lub taub hau countersunk: Qhov yuav tsum tau ua kom tiav qhov chaw, ib txwm muaj rau cov vaj huam sib luag ntawm lub cev tsheb thiab cov khoom siv aerospace
- Lub taub hau me me: Kev teeb tsa me me rau qhov chaw nqaim thiab cov tsev me me hluav taws xob
1.2.2 Qhov seem ntawm Rivet Shank uas tuaj yeem hloov pauv tau
Cov rivets dig muag: Lub hollow shank tw yuav tawg thiab ballooned rau hauv lub qhov xauv thaum lub mandrel rub los ntawm, tsim ib lub anchor tom qab tas mus li yam tsis tas yuav nkag mus rau tom qab ntawm lub rooj sib txoos.1.2.3 Lub Taub Hau
Lub mandrel yog ib lub pin hlau sib cais uas khiav hla lub hollow rivet shank, ib qho tseem ceeb rivet tshwj xeeb rau pop/dig muag rivets.
1.2.4 Lub Tshuab Ntxuav Thiab Lub Qhov Rooj Xauv (Cov Khoom Siv Rivet Tshwj Xeeb)
Rau cov rivets uas tsis muaj dej nkag thiab cov rivets uas muaj kev co siab, cov khoom rivet ntxiv raug phim rau lub shank:
l Roj hmab/nylon sealing washer: Haum ntawm lub taub hau rivet thiab vaj huam sib luag los thaiv dej, plua plav thiab roj nkag mus rau sab nraum zoov thiab hluav taws xob enclosures
l Lub dab tshos xauv hlau: Siv rau ntawm Huck lub nplhaib-grooved rivets, xauv rau ntawm qhov deformed shank groove kom tshem tawm loosening nyob rau hauv kev co tshuab tas mus li (tsheb thauj khoom, tshuab hnyav, khoom siv tsheb ciav hlau)
2: Kev faib tawm ntawm cov khoom sib txuas ntawm Rivet
Cov khoom ntawm rivet raug muab faib ua pawg los ntawm kev tsim qauv ntawm rivet, vim txhua pawg muaj cov qauv sib txawv ntawm cov shank thiab cov khoom txhawb nqa.
2.1 Cov Cheebtsam Rivet Ib Daim (Lub cev khov kho, Ib Chav Shank Sib Koom Ua Ke)
Cov rivets no tsuas muaj ob lub hauv paus rivet: lub taub hau ua los ntawm cov hlau + lub shank khov kho, tsis muaj lub mandrel sab hauv sib cais. Kev teeb tsa yuav tsum tau nkag mus rau ob sab ntawm cov khoom ua haujlwm kom hloov pauv lub shank tus tw.
2.2 Ob Daim Qhov Muag Tsis Pom Rivet Cheebtsam (Hollow Shank + Mandrel Sib Cais)
Hom rivet uas siv ntau tshaj plaws rau kev sib dhos ib sab, faib ua ob ntu rivet ywj pheej: rivet plhaub (hollow rivet shank) thiab mandrel pin. Cov pawg me raws li kev ua haujlwm ntawm shank:
- Tus qauv qhib qhov muag tsis pom kev rivets
l Kev puas tsuaj ntawm cov khoom siv rivet: lub taub hau flange + lub shank du hollow + lub mandrel hlau
- Cov rivets kaw-kawg kaw
l Kev puas tsuaj ntawm cov khoom siv rivet: Lub taub hau flange dav + lub shank hollow kaw tag nrho + mandrel tiv taus corrosion
- Cov rivets ntawm ntau lub qhov muag
l Kev puas tsuaj ntawm cov khoom siv rivet: Lub taub hau flange loj + lub shank nthuav dav uas hloov pauv tau + lub mandrel uas muaj zog heev
2.3 Cov Txheej Txheem Rivet Ntau Yam
Cov rivets uas tiv taus kev co hnyav uas ua los ntawm peb lossis ntau yam khoom rivet dhau ntawm lub hauv paus shank:
- Ring-grooved Huck rivets: Rivet sleeve (shank) + serrated mandrel + steel lock collar; lub shank muaj cov circumferential grooves uas interlock nrog lub collar tom qab mandrel rub tawm
- Tri-fold multi-grip rivets: Cov ceg tawv tuab + tus tw nthuav dav sib cais + mandrel tawv; peb-txoj kev shank nthuav dav muab kev tiv thaiv rub tawm zoo dua rau lub tsheb thauj khoom lag luam chassis
