Analýza tvářecích parametrů zkružování ocelových trubek

Abstract

The point of this thesis is an analysis of roll bending parameters for steel tubes. The analysis was simulated on two tubes representants D377-16 and D406-45 which represent thin-walled and also thick-walled tube profile of carbon steel 12 040. The bend of both representants was performed for a minimal bend radius and was analyzed in software for termomechanical treatment called QForm version 4.3.2. Theoretical part of this thesis includes description of technology analysis, study of principal processes and bending parameters.
