nws cov txheej txheem ntawm kev ua ib lub raj raj muaj ob peb kauj ruam uas ua kom cov khoom kawg muaj zog, ruaj, thiab zoo kawg nkaus zoo li tus. Rectangular raj yog ib qho tseem ceeb hauv ntau cov qauv, thiab nws yog ib qho tseem ceeb kom ntseeg tau tias lawv tau ua rau cov qauv siab. Ntawm no yog cov lus qhia ib kauj ruam dhau los rau kev ua cov raj duab plaub:
1. Kev xaiv cov khoom siv
Thawj kauj ruam yog xaiv cov khoom uas yuav siv los ua lub raj. Rectangular raj tuaj yeem tsim los ntawm ntau yam khoom xws li steel, aluminium, thiab stainless hlau. Cov khoom siv yog xaiv raws li cov kev cai tshwj xeeb ntawm daim ntawv thov ntawm lub raj.
2. Tube txiav
Tom qab ntawd cov khoom raug txiav mus rau hauv daim ntawm qhov ntev yuav tsum tau siv lub saw lossis laser cutter. Cov txiav yog ua tib zoo xyuas kom meej tias cov khoom yog tib qhov ntev thiab loj.
3. Tube txoj kev
Cov theem tom ntej yog tsim lub raj los ntawm kev khoov cov khoom. Cov txheej txheem sib txawv yog siv nyob ntawm seb hom khoom siv. Piv txwv li, steel tubes yog khoov siv lub tshuab mandrel, thaum txhuas raj tuaj yeem khoov tau siv hydraulic bender.
4. Vuam
Cov khoom ntawm lub raj yog ces welded ua ke siv ntau yam kev siv vuam xws li TIG vuam lossis MIG vuam. Cov welds yuav tsum tau ua tib zoo saib xyuas kom tsis txhob muaj qhov tsis xws luag uas tuaj yeem cuam tshuam lub zog ntawm lub raj.
5. Ua tiav
Qhov kawg theem yog ua kom tiav lub raj los ntawm smoothing tawm cov npoo ntxhib thiab siv cov txheej tiv thaiv. Lub raj yog tom qab ntawd tshuaj xyuas qhov tsis xws luag ua ntej tso tawm rau kev siv.
Cov txheej txheem ntawm kev ua lub raj plaub yog ib qho nyuaj uas yuav tsum muaj kev txawj ntse thiab kev txawj ntse. Txawm li cas los xij, nws yog ib qho tseem ceeb hauv kev tsim cov khoom muaj zog, ruaj khov, thiab zoo kawg nkaus zoo li cov hlab ntsha uas tuaj yeem siv rau hauv ntau yam qauv. Nrog rau cov ntaub ntawv zoo, cov cuab yeej siv, thiab cov txheej txheem, cov raj duab plaub tuaj yeem ua rau cov qauv siab heev, ua tau raws li qhov xav tau ntawm ntau yam kev siv.
