Riveted sib txuas: zoo thiab qhov tsis zoo

Riveted pob qij txha yog ua los ntawm tshwj xeeb qhov chaw. Nws yog tseem nyuaj rau cov daim ntawv cog lus. Rivets lawv tus kheej no yog ua los ntawm cov khoom siv hnab.

qauv

Riveted pob qij txha yog muaj li ntawm peb hais:

• ob qhov chaw yuav tsum tau tuaj koom;
• Rivet.

Qhov kawg lub caij yog muab tso rau hauv lub qhov uas muaj nyob rau ntawm cov npoo ntawm qhov chaw. Rivet tuas nyob rau hauv txoj hauj lwm ib sab. Nyob rau hauv cov ntaub ntawv no, Locking caij muaj xws li ib tug qauv:

• lub cev;
• tug pas nrig;
• BS lub taub hau - yog siv los hloov rau yav tom ntej ntawm cov khoom;
• kaw lub taub hau - yog tsim nyob rau hauv tus txheej txheem ntawm kev koom ob ntsiab.

Rau tsevneeg loj Cheebtsam siv los ntawm ib tug loj loj tus naj npawb ntawm rivets. Nyob rau hauv cov ntaub ntawv no, ib tug compound yuav raug xa mus tiav lawm RIVET ob leeg.

Liaj teb ntawm daim ntawv thov

Ua ntej lub advent ntawm high-zoo vuam riveted ob leeg qhov chaw lawm ntau. Tam sim no, nws yog siv nyob rau hauv tej cheeb tsam ntawm technology. Riveted pob qij txha ntawm qhov chaw siv nyob rau hauv kev tsim kho ntawm aircraft, ships, submarines, raws li zoo raws li rau ib tug ntau yam ntawm high-precision seev. Ntxiv mus, rivets siv thaum txuas lub tsev hais, xws li kuv-beams, raws, cov ces kaum. Lawv pab mus rau withstand nce mus nce los ntseeg loads. Riveted pob qij txha yog siv los muab ntau yam ntawm cov ntaub ntawv uas. Piv txwv li, rau cov tsevneeg khoom los ntawm cam khwb cia hlau hlau nrog txhuas daim ntawv.

Riveted pob qij txha. Zoo thiab tsis zoo ntawm cov lub ua ke txoj kev

Ntawm cov zoo sib nrauj tso tawm:

• yooj yim kev siv technology tshiab ua tau zoo;
• muaj peev xwm mus ua ke txawv co;
• High kev twb kev txuas kev ntseeg;
• resists co thiab poob siab loads.

Txawm li cas los, raws li txhua kev twb kev txuas, muaj ib co drawbacks, cov uas yog cov nram qab no:

• los ua ib tug RIVET tsevneeg, nws yog tsim nyog los siv ib tug loj npaum li cas ntawm cov hlau;
• Nws yuav tsum tau tseem ceeb ua hauj lwm rau cov nqi;
• siab them nqi;
• riveted pob qij txha yuav deteriorate vim kev txoj kab uas hla qhov uas nyob rau ntawm cov npoo ntawm cov khoom;
• thaum lub sij hawm kev lag luam compound ceev ceev lawm.

Hom ntawm rivets yog ib tug heev ob peb, vim txhua yam uas lawv yuav siv nyob rau hauv ib qho kev ua lag luam.

Riveted pob qij txha: kev faib

Qhov no hom ntawm kev twb kev txuas yog muab faib raws li lub hauv paus ntsiab lus:

1. Functionality. Ntawm cov tebchaw muaj peb hom: khoom siv los tuav hnyav loads; ntom, muab ceev ceev; Ua ke - ua ob zog.

2. Technological leeg siv. Lub txuas leeg yuav tsum tau ua los ntawm overlapping thiab taub qab. Cov yav tas hom yog tau siv ib los yog ntau tshaj los.

3. Tus naj npawb ntawm cov slices. Qhov no xam pom tias tus naj npawb ntawm slices extending los ntawm ib tug RIVET nyob rau hauv load. Raws li txoj ntsiab cai no, riveted pob qij txha yog ib thiab mnogosreznye. Lawv tus xov tooj yog tsis tas.

4. Tus nab npawb ntawm riveting series. Tej zaum yuav muaj ib tug, ob tug, peb, thiab hais txog. D. Tus xov tooj yog tsis txwv.

Raws li twb tau hais, riveted sib txuas yog siv nyob rau hauv ntau yam industries. Yog li ntawd, muaj ntau ntau yam hom ntawm rivets. Nyob rau hauv tas li ntawd mus rau cov indicators, As, cov no yog txwv kom muab zais raws li hauv daim ntawv ntawm mortgages hau:

• semicircular;
• tsis pub leejtwg paub;
• tsa countersunk;
• cylindrical.

pas nrig

Raws li hauv daim ntawv muaj xws li xws hom:

• khoom;
• hollow (muaj ib tug los ntawm-qhov);
• polupustotelye - pas nrig yog muab faib ua ob qhov chaw: ib tug yog khoom, thiab lwm yam - ib tug nqi li.

Cov ntaub ntawv hais txog tsevneeg thiab yam yog muaj nyob rau hauv tus txheej txheem cov ntaub ntawv. Characterizing riveted pob qij txha GOST 10303-68 muaj xws li yooj yim ntau yam rivets. Muaj tsim nws txoj kab uas hla, ntev thiab pas nrig thiab lub taub hau hom.

khoom

Lub ntsiab ntaub ntawv rau lub RIVET kev twb kev txuas yog cov uas tsis muaj hlau, uas tsis yog-ferrous co thiab ib co alloys. Dua li no, txhua cov ntaub ntawv uas nruj uas yuav tsum tau:

• Yuav kom pab txhawb lub installation ntawm cov khoom cov ntaub ntawv uas yuav tsum tau cov yas.
• Ntaub ntawv yuav tsum muaj tib lub thermal expansion tus nqi. Tsis uas lub neeg pab leg ntaubntawv yuav tshwm sim thaum ntxiv kev nyuaj siab kub dauv. Thaum kawg riveted pob qij txha puam tsuaj.
• Ntaub ntawv yuav tsum muaj uniform. Qhov no yog los xyuas kom meej tias ib tug galvanic tam sim no tsis ua kom puas lub kev twb kev txuas. Piv txwv li, rau cov tsevneeg ntawm steel Cheebtsam, steel studs siv, cov ntsiab tooj liab - tooj liab, thiab lwm yam ...

loads

Tau raug pom tias yog raws li ib tug tshwm sim ntawm heev heev kev ntsuam xyuas thiab kev txom nyem. Nyob rau hauv tas li ntawd, lawv tau raug ua tib zoo kawm los ntawm cov kws txawj. Muaj ob peb hom kev nyuaj siab: kev nyuaj siab shear, ncab ib ce thiab wrinkling. Rau txhua hom ntawm cov hlau tej cim no txawv los ntawm txhua lwm yam.

Los ntawm kev siv ob lub ntsiab me steel tensile load peev xwm yuav tsum tsis txhob ntau tshaj 150 MPa thiab cov shear kev nyuaj siab yuav tsum tsis ntau tshaj 100 MPa.

Nws yuav tsum tau muab sau tseg tias cov indicators tau tsim tsis tsuas yog rau cov txuas ntsiab, tab sis kuj rau rivets. Rau lawv, muaj lawv tus kheej permissible load. Piv txwv li, rau cov khoom uas ntawm cov hlau shear kev nyuaj siab yuav tsum tsis pub tshaj 100 MPa. Nyob rau hauv crushing, nws tsis yog ntau tshaj li 300 MPa.

Permissible loads ntsiab nyob ntawm seb tus qauv ntawm cov qhov nyob rau hauv cov khoom. Yog hais tias muaj yog ib tug loj voltage, qhov yuav tsum tau ua los ntawm drilling.

Nyob rau hauv cov ntaub ntawv ntawm ib tug ib ntus tej yam nyob rau hauv cov khoom permissible load yog txo los ntawm 20%. Nyob rau hauv tej rooj plaub, xws li tus mob khaub thuas RIVET, qhov no daim duab dauv mus rau 30%.

Pom zoo rau zus tau tej cov riveted pob qij txha

Cov no yog cov general raug tebchaw tau tsim los ntawm heev tsim nyog tshwj xeeb. Lawv qhia raws li ib tug tshwm sim ntawm lub xyoo ntawm kev soj ntsuam nyob rau hauv lub laboratory thiab nyob rau hauv-kev pab cuam sib txuas. Yog li ntawd, cov lawv yog:

1. Cov txuas qhov chaw thiab rivets yuav tsum tau ua los ntawm check homogeneous khoom.

2. rivets yuav tsum tau muab me ntsis attenuation nqi ntawm qhov chaw. Rau lub hom phiaj no, raws li ib tug txoj cai, kuv siv ib tug chess txoj kev uas yuav ntsaub.

3. Tsis txhob muaj cov tsos ntawm dabtsi yog khoov lub ntsiab yam ntxwv ntsiab. Yuav kom qhov no kawg, ib tug RIVET raws axis uas sau los ntawm qhov chaw ntawm kev cob cog rua ntsiab.

4. Thaum ib tug RIVET kev twb kev txuas yuav siv tsis tau lub ntsiab uas muaj ntau diameters.

5, tus xov tooj ntawm rivets yuav tsum muaj tsawg kawg yog ob tug los mus tiv thaiv kev sib hloov ntawm qhov chaw.

6. Cov nab npawb ntawm cov ntsiab ntawm ib sab yuav tsum tsis ntau tshaj li peb. Los ua lub dag lub zog ntawm cov khoom ntawm qhov ntsuas no yuav txo tau.

7. taub qab ob leeg yuav tsum tau siv ntau piv nrog riveting compound sib tshooj.

8. Xyuas kom ceev ceev. Yuav kom qhov no kawg, nyob rau hauv qhov chaw ntawm rivets thov tshwj xeeb kua nplaum los yog xim, uas yog tau ua los ntawm nplaim taws Txau.

9. Tom qab phiaj qhov chaw yog nqa tawm los ntawm.

10. Tus nab npawb ntawm rivets nyob rau hauv peb tes num tsim ib tug riveted ob leeg.

Qhov no kev twb kev txuas yog tsis heev nyob rau hauv peb lub sij hawm. Nws yuav luag tag supplanted welding. Txawm li cas los, nws yog siv nyob rau hauv qhov siv thiab ua aircraft, ships, raws li zoo li ib co kiag li lawm. Lub ntsiab zoo muaj zog ntawm lub kawg kev twb kev txuas thiab yooj yim installation. Txawm li cas los, siv nws, koj yuav tsum siv ib tug tseem ceeb npaum li cas ntawm cov hlau. Yog li ntawd, qhov no hom ntawm kev twb kev txuas yog kim thiab lub sij hawm siv.

xaus

Rivets, muaj ntau ntau yam. Lub ntsiab yam thiab ntau thiab tsawg ntawm rivets teev nyob rau hauv lub ntxawg cov ntaub ntawv. Saib caij nyob rau hauv lub lag luam. Txhim kho lawv yuav tsum tau leej tiav. Lub slightest sib txawv nyob rau hauv txoj kab uas hla ntawm lub qhov yuav ua tau kom puas tsuaj ntawm tag nrho cov khoom. Nyob rau hauv lawv cov khoom yuav tsum tau ua raws li tej yam kev cai, uas tau kos mus txog ntawm cov kws txawj nyob rau hauv lub hauv paus ntawm ntev-lub sij hawm cov lus teb thiab ua thwmsim.

Yog li ntawd, peb ntsia cov yam ntxwv ntawm no hom ntawm tebchaw.
