Hom thiab ntau thiab tsawg ntawm cov rivets hlau yog qhov tseem ceeb heev rau kev tsim kho thiab teeb tsa ua haujlwm. Muaj rivets nrog lub taub hau ib nrab rau riveter, countersunk, tsav thiab lwm yam qauv. Lawv qhov loj me muaj ntau yam los ua li cas ib qho tshwj xeeb tuaj yeem siv tau.

Nqe lus piav qhia

Loj-tsim cov hlau rivets yog tus yam ntxwv ntawm ntau txoj haujlwm niaj hnub no hauv ntau yam kev lag luam. Nws tsim nyog xav tias txoj kev riveting tau siv dav heev, thiab tsis yog tsuas yog ua haujlwm nrog cov khoom siv hlau. Riveted pob qij txha kuj tseem siv hauv khaub ncaws thiab khoom siv ntxiv . Thaum ua haujlwm nrog hlau, rivets hlau yog qhov muaj txiaj ntsig ntau dua li cov ntsia hlau sib txuas.

Ceev thiab ntsia liaj qhov rooj yog kim dua thiab tsis tuaj yeem ua haujlwm nrawm dua.

Hom kev txheeb xyuas

Cov khoom lag luam nrog lub taub hau semicircular tau nthuav dav. Cov khoom no ua tau raws li qhov yuav tsum tau ua ntawm GOST 10299-80. Txoj kab hla ntawm tus pas nrig yog los ntawm 0, 1 txog 3, 6 cm. Cov hlau rivet rau cov rauj rauj yuav tsum tau ua raws li GOST 10300-80. Rau cov khoom lag luam nrog lub taub hau tiaj tus, tus qauv 10303-80 siv. Thaum kawg, rau kev kuaj ib nrab hollow, GOST 12641-80 tau siv.

Rau kev tsim cov khoom siv no, siv cov hlau hauv qab no:

• 10kp; ib.
• 15kp; ib.
• St2;
• St3.

Tag nrho cov hlau txuas rivets muaj peev xwm nqa tau zoo heev. Txawm li cas los xij, nws nyuaj heev los tsim lawv. Hom ib nrab hollow yog tsim nyob rau hauv xws li ib txoj kev uas seem ntawm tus pas nrig nyob ze ntawm lub taub hau ntxig yog ib nrab khoob . Thaum kawg, cov khoom hollow tau yooj yim rau rivet. Qhov ntxeev ntawm qhov kom zoo dua no yog qhov tsis txaus ntseeg kev sib txuas. Semicircular hau tuaj yeem muaj qhov siab sib txawv. Lawv siv yog txiav txim siab qhov kev daws teeb meem zoo tshaj plaws los ntawm qhov pom ntawm kev ntseeg tau thiab ruaj khov ntawm kev sib khi tau tsim.

Hauv ib puag ncig txhoj puab heev, rivets nrog lub taub hau cylindrical lossis lub taub hau zoo li yog siv . Countersunk thiab semi-hidden yam xav tau yog tias koj xav tshem tawm qhov tsim ntawm protrusion saum nplaim. Cov kev tsim vaj tsev no tsuas yog siv rau qhov xwm txheej uas tsis muaj lwm txoj hauv kev tsim nyog rau lawv. Ib hom thoob ntiaj teb rau tus riveter hauv cov duab zoo ib yam li lub ntsej muag ntawm cov nceb. Ib pawg cais tau suav nrog, tso pa tawm, rub tawm thiab tshem tawm cov khoom lag luam. Xws li kho vajtse muaj ob ntu tseem ceeb. Tsis tas yuav tsum tuav lawv nyob rau lwm sab ntawm lub seam. Qhov xwm txheej no zoo nkauj heev thaum tsim cov laj kab thiab tsim cov ru tsev.

Qee zaum muaj cov npe hu ua rivets. Lawv tau siv thaum nws tsim nyog los txuas ntu nrog cov phab ntsa tshwj xeeb (tsis ntau dua 0.03 cm). Sab hauv muaj cov xov tshwj xeeb, thiab sab nrauv muaj qhov thais ntsug uas thaiv kev sib hloov ib puag ncig nws cov axis. Tsav rivets feem ntau yog tsim los ntawm:

• tooj dag;
• txhuas;
• tooj liab (thiab txhua yam khoom lag luam tau suav rau rauj, lawv tsis xav tau tus riveter).

Qee lub sij hawm zinc txheej tau siv los txhim kho kev txhim kho corrosion. Ob qho "txias" thiab "kub" galvanizing qhia nws tus kheej zoo. Tom qab cov txheej txheem no, tsis tsuas yog ua tau zoo dua qub, tab sis kuj tseem pom kev pom ntawm cov khoom. Tseem ceeb: nws yog qhov yuav tsum tau coj mus rau hauv tus account qhov tsim ntawm galvanic khub thiab cov tshuaj tiv thaiv hluav taws xob ntawm lawv. Cov tooj liab-hlau ua rau ua kom nrawm dua ntawm cov khoom.

Qhov ntev (kho kom raug)

Ib qho hlau rivet tuaj yeem yog 2 txog 8 hli inch. Qhov ntev yog los ntawm 6 txog 65 hli. Hauv cov khoom lag luam loj, cov khoom siv kho vajtse feem ntau siv nrog ntu ntu:

• 3;
• 3, 2;
• 4;
• 4, 8;
• 5;
• 6;
• 6.4 hli.

Qhov ntev ntawm lub riveted fastener cuam tshuam rau qhov tuab ntawm ntu thiab qhov chaw kom koom nrog. Raug piv piv:

• 3.0x6 - rau tuab los ntawm 1.5 txog 3.5 hli;
• 3.0x16 - rau txheej ntawm 11 txog 13 hli;
• 3.0x20 - rau txheej ntawm 15 txog 17 hli;
• 3, 2x14 - rau tuab ntawm 9 txog 11 hli;
• 4, 0x28 - rau cov khoom lag luam los ntawm 21.5 txog 24 hli.

Yuav siv li cas?

Nws tsis nyuaj rau siv rivets - rau cov khoom cylindrical, koj tuaj yeem ua txawm tias tsis muaj cov cuab yeej tshwj xeeb, rauj zoo tib yam rauj yog txaus. Koj tuaj yeem ua haujlwm tau zoo txawm tias nyob hauv "thaj chaw", tsis hais txog kev ua haujlwm puv ntoob. Cov hlau loj tshaj plaws yog siv hauv kev sib dhos ntawm cov choj thiab hla hla. Cov khoom lag luam me yog xav tau hauv kev siv tshuab thiab tsim khoom. Tseem ceeb: riveted pob qij txha tsis nruj txaus los ntawm lub neej ntawd, thiab nws muaj peev xwm ntim lawv kom raug tsuas yog siv cov sealants thiab tshwj xeeb hom roj hmab.

Feem ntau lub qhov yog ua ntej ua ntej. Yog tias siv rivet countersunk rivet, suav nrog countersink. Tus txheej txheem ntawm qhov muag tsis pom rivet yog ib yam zoo li no:

• ntxig ib lub rivet;
• rub ua ke cov ntsiab lus tsim nyog;
• tsim lub taub hau kaw (siv lub cuab yeej);
• xyuas qhov kev npaj ntawm qhov txuas, yog tias tsim nyog, ntxuav nws.

Yog tias koj muaj cov cuab yeej tsim nyog, txoj haujlwm mus sai heev. Hauv kev xyaum ntiag tug, kev siv riveters siv. Txoj haujlwm yuav siv sijhawm li ob peb feeb. Kev siv sijhawm ntev dua. Cov qhov hauv daim ntawv profiled tau pleev xim rau kom tiv thaiv kev xeb.
