Flash taub qab vuam yog cov txheej txheem siv dav hauv ntau qhov kev lag luam rau kev koom nrog ob daim hlau ua ke. Nws suav nrog ntau theem tseem ceeb, ib qho yog theem siab. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv cov ntsiab lus ntawm lub upsetting theem nyob rau hauv lub flash taub qab vuam tshuab, nws qhov tseem ceeb, thiab cov yam ntxwv uas cuam tshuam rau qhov zoo ntawm lub vuam.
Lub Upsetting Theem hauv Flash Butt Vuam
Qhov kev ntxhov siab yog ib feem tseem ceeb ntawm cov txheej txheem flash pob tw. Thaum lub sij hawm no, ob lub hlau workpieces raug nias tawm tsam ib leeg thaum muaj hluav taws xob tam sim no dhau los ntawm lawv. Qhov no ua rau mob siab rau hauv cheeb tsam cua sov ntawm qhov sib cuam tshuam ntawm cov workpieces, ua rau tsim ib cheeb tsam molten. Raws li qhov tam sim no txuas ntxiv mus, cov workpieces raug coj mus rau hauv kev sib cuag, forging muaj zog thiab ruaj khov weld.
Qhov tseem ceeb ntawm lub Upsetting Stage
Qhov zoo ntawm cov welding nyob rau hauv flash pob tw welding yog hnyav heev nyob ntawm lub upsetting theem. Kev ua kom raug kev ntxhov siab kom ntseeg tau tias ob lub workpieces tau ruaj ntseg koom nrog, nrog rau kev sib koom ua ke zoo heev. Nws kuj tseem tshem tawm cov kab mob los yog cov oxide txheej ntawm cov hlau, uas ua rau muaj kev huv thiab ruaj khov.
Factors Influencing Upsetting Stage
Ntau yam tuaj rau hauv kev ua si thaum lub sij hawm ntxhov siab, cuam tshuam rau qhov kawg ntawm qhov vuam. Qee yam tseem ceeb uas yuav tau xav txog suav nrog:
- Tam sim no Amplitude:Tus nqi ntawm cov hluav taws xob tam sim no dhau los ntawm cov khoom ua haujlwm txiav txim siab cov cua sov uas tsim los thaum ntxhov siab. Kev tswj cov tam sim no yog qhov tseem ceeb los tiv thaiv overheating lossis underheating, uas tuaj yeem ua rau lub vuam tsis muaj zog.
- Lub Sijhawm Ntev:Lub sijhawm siv tam sim no cuam tshuam rau cua sov thiab melting ntawm workpiece interface. Nws yog ib qho tseem ceeb los xyuas kom meej qhov tsim nyog sib npaug ntawm lub sij hawm thiab qhov kub thiab txias kom ua tiav qhov xav tau weld zoo.
- Siab thiab quab yuam:Lub zog siv los nqa cov workpieces rau hauv kev sib cuag, hu ua forging siab, plays lub luag haujlwm tseem ceeb. Lub siab yuav tsum tau ua tib zoo calibrated los xyuas kom meej ib tug uniform thiab muaj zog daim ntawv cog lus.
- Khoom siv:Hom thiab muaj pes tsawg leeg ntawm cov khoom raug welded cuam tshuam rau theem siab. Cov hlau sib txawv muaj qhov sib txawv ntawm cov hluav taws xob thiab thermal conductivity, uas cuam tshuam rau qhov lawv teb rau cov txheej txheem vuam.
- Surface condition:Qhov chaw ntawm lub workpieces yog qhov tseem ceeb. Cov chaw huv, npaj kom zoo ua rau cov welds zoo dua. Txhua yam kab mob los yog oxides ntawm cov hlau tuaj yeem cuam tshuam qhov zoo ntawm cov vuam.
Nyob rau hauv xaus, lub upsetting theem nyob rau hauv flash pob tw welding yog ib tug tseem ceeb theem nyob rau hauv tus txheej txheem, thiab nws tsim nyog ua yog ib qho tseem ceeb rau ua tau zoo welds. Kev nkag siab thiab tswj cov yam tseem ceeb uas cuam tshuam rau theem no yog qhov tseem ceeb rau kev ua kom muaj zog, ruaj khov, thiab txhim khu kev qha welds hauv ntau hom kev siv. Nws yog ib qho tseem ceeb rau cov welders thiab engineers yuav tsum tau ua tib zoo saib xyuas cov yam ntxwv no kom tas li tsim cov pob tw welds saum toj kawg nkaus.
