Q: Dab tsi yog cov txheej txheem kev ua haujlwm tseem ceeb rau Q235 txias- cov ntawv dov steel siv hauv tsheb?
A: Cov txheej txheem tseem ceeb yog bending, stamping, vuam, thiab shearing. Qee qhov yuav tsum tau xuas nrig ntaus, dov, thiab riveting. Vim muaj kev txwv formability, kev kos duab sib sib zog nqus tsis tshua siv.
Q: Dab tsi yuav tsum tau ceev faj thaum stamping Q235 txias -rolled steel ntawv rau tsheb qhov chaw?
A: Vim tias qhov sib sib zog nqus nqus kev ua tau zoo feem ntau tsis zoo, zam dhau qhov tob stamping. Tswj stamping ceev thiab tuag clearance los tiv thaiv cracking thiab wrinkling ntawm daim ntawv cov ntaub ntawv. Ntxuav saum npoo ua ntej stamping kom tsis txhob khawb uas tuaj yeem cuam tshuam rau tom qab kev kho deg.
Q: Dab tsi yog cov txheej txheem vuam rau Q235 txias- cov nplooj ntawv steel siv hauv tsheb? Qhov twg yog qhov feem ntau siv?
A: Spot welding, CO2 gas shielded vuam, arc vuam, thiab brazing tuaj yeem siv tau. Spot welding yog feem ntau siv nyob rau hauv kev lag luam tsheb, haum rau cov khoom siv, siab - vuam kev xav tau ntawm lub cev. Tom qab vuam, tsis muaj qhov pom tseeb vuam qhov tsis xws luag, thiab lub zog ua tau raws li qhov yuav tsum tau ua rau cov khoom tsis yog - tseem ceeb.
Q: Dab tsi yog qhov dabtsi yog khoov vojvoog rau dabtsi yog khoov Q235 txias-cov ntawv hlau dov?
A: Nyob rau hauv chav tsev kub, qhov tsawg kawg yog dabtsi yog khoov vojvoog ntawm txias- dov Q235 yog kwv yees li 0.5-1 npaug ntawm daim ntawv thickness. Hauv kev ua cov khoom siv hauv tsheb, kom tsis txhob muaj kab nrib pleb ntawm qhov khoov, lub vojvoog dabtsi yog khoov ntawm 1 npaug ntawm daim ntawv tuab feem ntau xaiv.
Q: Vim li cas cov khoom siv tsheb ua los ntawm Q235 txias- cov ntawv dov tau txais kev kho degreasing thiab phosphating?
A: Degreasing tshem tawm cov roj thiab impurities los ntawm kev ua, kom ntseeg tau adhesion rau cov txheej tom ntej. Phosphating tsim cov phosphate zaj duab xis rau ntawm daim ntawv, txhim kho corrosion kuj thiab adhesion rau electrophoresis thiab painting, tiv thaiv xeb.
