Kab lus no tshawb txog lub tswv yim ntawm pre-forging nyiaj pub dawb hauv cov tshuab vuam. Pre-forging nyiaj pub dawb, tseem hu ua pre-bending lossis pre-heating, yog ib qho tseem ceeb hauv cov txheej txheem vuam uas pab tiv thaiv qhov cuam tshuam ntawm kev cuam tshuam thaum vuam. Tsab xov xwm tham txog qhov tseem ceeb ntawm qhov nyiaj pub ua ntej forging, nws cov txiaj ntsig zoo, thiab nws qhov cuam tshuam rau qhov zoo ntawm vuam thiab kev ua haujlwm. Welders tuaj yeem tau txais txiaj ntsig los ntawm kev nkag siab thiab siv cov txheej txheem no kom ua tiav qhov tseeb thiab tsis muaj kev cuam tshuam welds.
Pre-forging nyiaj pub dawb yog cov txheej txheem tseem ceeb ua haujlwm hauv cov tshuab vuam kom txo tau cov kev sib tw ntawm kev sib tw los ntawm kev vuam. Nws koom nrog kev siv tswv yim ntawm cov khoom ua ntej vuam, ua rau muaj kev tswj xyuas ntau dua thiab raug vuam txheej txheem.
- Kev nkag siab txog Pre-Forging Allowance Pre-forging pub yog hais txog me ntsis deformation lossis khoov ntawm lub workpiece ua ntej vuam. Cov txheej txheem no yog txhawm rau them nyiaj rau cov thermal stresses thiab distortion uas tshwm sim thaum lub vuam txheej txheem. Los ntawm kev ua ntej forging lub workpiece, welders tuaj yeem ua tiav kev sib raug zoo thiab haum, txo qhov kev pheej hmoo ntawm kev deformation tom qab vuam.
- Kev txiav txim siab qhov zoo tshaj plaws Pre-Forging Allowance Qhov zoo tshaj plaws pre-forging pub nws txawv nyob ntawm seb cov khoom siv welded, kev sib koom tsim, thiab cov txheej txheem vuam siv. Welders thiab engineers yuav tsum xav txog tej yam xws li cov khoom siv, thickness, thiab vuam tsis tau los txiav txim qhov tsim nyog pre-forging pub rau ib daim ntawv thov. Ua kom tiav qhov sib npaug yog qhov tseem ceeb kom tsis txhob muaj kev khoov dhau, uas tuaj yeem ua rau muaj teeb meem xws li weld shrinkage thiab distortion.
- Kev cuam tshuam rau Weld Zoo thiab kev ua tau zoo Kev siv qhov tsim nyog ua ntej forging tuaj yeem txhim kho qhov zoo thiab kev ua haujlwm zoo. Los ntawm kev txo qis distortion, cov txheej txheem ua kom ntseeg tau tias qhov sib koom ua ke khaws nws cov duab thiab qhov ntev. Cov welds tsis muaj kev cuam tshuam ua rau muaj kev txhim kho cov qauv kev ntseeg siab, qhov tseeb qhov tseeb, thiab tag nrho cov weld zoo nkauj.
Daim Ntawv Thov Cheeb Tsam: Cov nyiaj pub ua ntej forging feem ntau yog siv rau hauv ntau yam kev siv vuam, nrog rau lub taub qab vuam, vuam fillet, thiab T-joint welding. Nws yog qhov tshwj xeeb tshaj yog thaum ua haujlwm nrog cov ntaub ntawv tuab lossis cov txheej txheem sib koom ua ke, qhov kev sib txawv yuav tshwm sim ntau dua.
Pre-forging nyiaj pub dawb yog cov txheej txheem tseem ceeb hauv cov tshuab vuam uas pab daws cov teeb meem ntawm kev cuam tshuam thaum vuam. Los ntawm kev sib txuas cov qauv no rau hauv cov txheej txheem vuam thiab txiav txim siab qhov kev pom zoo raws li cov khoom siv thiab kev sib koom ua ke, cov welds tuaj yeem ua tiav qhov tseeb thiab tsis muaj kev cuam tshuam welds. Daim ntawv thov kev vam meej ntawm pre-forging nyiaj pab txhawb kev txhim kho weld zoo, kev ua haujlwm ruaj khov, thiab kev ua haujlwm vuam tag nrho. Raws li kev coj ua hauv kev lag luam welding, pre-forging nyiaj pab txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev ua kom cov khoom zoo thiab txhim khu kev qha weld pob qij txha.
