Defects in Rotary Draw Bending and Their Effects on Formability

Abstract

Tube with different quantities and types; It can be described as a long and narrow cylinder with open ends, which carries liquids, gases and similar substances from one place to another. Tubes are used for advancements in sectors such as transportation, automobiles and aerospace. Aluminum, Inconel and titanium materials are decided according to the required needs in the design and production of tubes. There are different production methods to give permanent shape to the tubes. During tube bending operations, the feasibility of tube bending varies depending on the material type, bending angles, bending radius, tools and process. The tubes produced with a certain margin of defect. Some defects occur during and after production. Springback, ovality, breakage and tearing are among these defects. These defects may prevent the system to be replaced from flowing with the desired properties, as well as the installation of the produced tubes. The aviation and space fields, the production of tubes with high strength and complex geometries is critical. Errors that occur in the rotary draw bending process, one of these pipe bending methods, and the steps to prevent these errors are compiled and presented.
