Hom Welded Splice Joint thiab Kev Sib Txuas Txoj Kev

Cov rivets feem ntau yog cais raws li hauv qab no:

• Kub-driven rivets: Cov rivets uas tau tsav nyob rau hauv qhov kub kub
• Cov khoom rivets: Cov rivets uas muab tso rau hauv lub rooj cob qhia
• Field rivets: Cov rivets uas muab tso rau hauv qhov chaw / teb.

Txias-tsav rivets: Txij li thaum muaj kev kub siab yuav tsum tau tsim lub taub hau ntawm chav tsev kub qhov no hom rivet yog txwv.

Zoo: Txhim khu kev sib kis tau zoo, zoo toughness thiab plasticity, yooj yim soj ntsuam zoo, zoo kuj rau dynamic loads

tsis zoo: complex qauv, kim steel thiab kev ua haujlwm

Txawm hais tias muaj peb txoj kev sib txuas rau steel qauv engineering, vuam yog txoj hauv kev tseem ceeb hauv cov txheej txheem tsim khoom ntawm cov khoom siv. Qhov zoo ntawm cov khoom welded muaj feem xyuam rau qhov zoo ntawm cov khoom siv nyob rau hauv tag nrho lub tsev. Yog li ntawd, welding yuav tsum tau welded tag nrho, yuav tsum tsis txhob plam vuam.

Txoj Kev Sib Txuas Tseem Ceeb

Cov qauv hlau tuaj yeem muab faib ua cov qauv welded, cov qauv bolted thiab cov qauv riveted raws li lawv txoj kev sib txuas. Txoj kev txuas tseem ceeb ntawm cov qauv hlau tam sim no yog vuam, bolting thiab rivet txuas.

Vuam

Vuam kev sib txuas yog txoj kev sib txuas tseem ceeb tshaj plaws rau cov qauv hlau tam sim no, tseem hu ua vuam, uas feem ntau yog siv qhov kub thiab txias, cua sov lossis kub siab los ua ke cov cuab yeej siv hlau. Muaj ntau txoj hauv kev vuam, xws li tes arc vuam, submerged arc vuam, tungsten TIG vuam, roj hlau arc vuam, thiab lwm yam. Qhov kev siv tiag tiag yog nyob ntawm qhov xav tau tiag tiag.

Zoo: Cov qauv yooj yim, cov khoom txuag, kev ua haujlwm yooj yim, thiab kev ua haujlwm tsis siv neeg tuaj yeem txais yuav,

tsis zoo: Cov kev xav tau siab rau cov khoom siv, vuam yuav ua rau cov txheej txheem deformation thiab cov kev ntxhov siab nyob hauv thaj chaw muaj kev kub ntxhov, yog li nyob rau hauv cov txheej txheem vuam, nws yuav tsum tau ntxiv dag zog rau kev tiv thaiv vuam deformation tsis xws luag thiab kho lawv raws sijhawm.

Bolted Kev sib txuas

Bolted kev twb kev txuas kuj yog ib txoj kev sib txuas ntau dua, uas yog siv cov bolts kom dhau los ntawm lub qhov ntawm ob qhov chaw yuav tsum tau txuas nrog, tom qab ntawd muab cov ntxhua khaub ncaws, thiab ceev ceev. Txoj kev no muaj qhov zoo ntawm kev sib dhos yooj yim thiab nrawm thiab tuaj yeem siv rau hauv cov qauv kev sib txuas thiab cov qauv tsim tawm.

Qhov tsis zoo yog qhov seem ntawm cov khoom tsis muaj zog thiab yooj yim rau loosen. Muaj ob hom kev sib txuas bolted: zoo tib yam bolted kev sib txuas thiab kev sib txuas siab bolted. Lub peev xwm sib koom ua ke ntawm lub zog muaj zog bolts yog siab dua li cov bolts zoo tib yam, thiab kev sib txuas ntawm cov ntsia hlau muaj zog tuaj yeem txo qhov tsis muaj zog ntawm cov ntsia hlau qhov ntawm cov khoom, yog li lawv tau siv dav.

Ntawm lawv, muaj cov bolts zoo tib yam thiab muaj zog bolts. Ordinary bolts feem ntau yog ua los ntawm cov pa roj carbon zoo tib yam uas tsis muaj kev kho cua sov. High-strength bolts feem ntau yog ua los ntawm high-zoo carbon structural steel los yog alloy structural steel, uas yuav tsum tau quenched thiab tempered los txhim kho cov khoom txhua yam.

Lub zog siab tau muab faib ua qib 8.8, qib 10.9, thiab qib 12.9. Los ntawm qib zog: Lub zog muaj zog bolts feem ntau siv hauv ob qib zog ntawm 8.8S thiab 10.9S. Ordinary bolts feem ntau muaj qib 4.4, 4.8, 5.6 thiab 8.8. High-strength bolts siv pre-tensioning quab yuam thiab xa mus rau sab nraud quab yuam los ntawm kev sib txhuam, thiab zoo tib yam bolts kis shearing quab yuam los ntawm bolt pas nrig shear kuj thiab lub phab ntsa bearing siab.

Ordinary bolt ckev sib txuas

Zoo: yooj yim loading thiab unloading, yooj yim cov cuab yeej

tsis zoo: Thaum lub bolt raug qis, nws tsis haum rau kev tshuaj xyuas. Thaum lub bolt raug siab, kev ua haujlwm thiab kev teeb tsa yog qhov nyuaj thiab tus nqi siab.

High-strength bolt kev twb kev txuas

Zoo: Cov kev sib txhuam hom muaj me me shear deformation thiab zoo elastic kev ua tau zoo, tshwj xeeb tshaj yog haum rau cov qauv nrog kev ua raws li cov loads. Cov kabmob muaj peev xwm ntawm lub siab-cov kabmob yog siab dua li ntawm kev sib txhuam, thiab kev sib txuas yog compact.

tsis zoo: Kev sib txhuam nto yog kho, cov txheej txheem installation yog me ntsis nyuaj, thiab tus nqi yog me ntsis siab dua; shear deformation ntawm lub siab-cov kabmob kev twb kev txuas yog loj, thiab nws yuav tsum tsis txhob siv nyob rau hauv cov qauv uas dais dynamic loads.

Kev sib txuas rivet

Ib qho kev sib txuas tsis zoo li qub uas siv rivets los txuas ob lossis ntau yam khoom (feem ntau yog cov phaj lossis cov ntawv) ua ke, hu ua riveting. Rivet kev twb kev txuas muaj cov yam ntxwv ntawm cov cuab yeej yooj yim, txhim khu kev qha kev twb kev txuas thiab hom tsis tshem tau.
