Tvářecí parametry trubkových oblouků

Abstract

This study describes the modification of forming parameters of tube bending. Specifically, it discusses the bending of large diameter steel pipes using local heat and cooling and includes the analysis of thermo-mechanical parameters. It also discusses the different forces used in bending tools and evaluates their influences on work flow. The main objective of the study is to specify the existing technology for heat bending and to minimize any adverse side effects in order to maintain the shape tolerances in cross-sections of the tube after the bending is finalized.
