Design of a fuzzy controller to prevent wrinkling during rotary draw bending [PDF]
ESAFORM 2021, 2021 Rotary draw bending (RDB) is a forming process that is commonly used to bend tubes with small wall thicknesses and small bending radii. One of the limitations of this process is the formation of wrinkles caused by compressive stress on the inner bend.

Analisa Pengaruh Variasi Mandrel Terhadap Toleransi Pipa Pada Rotary Draw Bending
PROTON, 2023 Rotary Draw Bending is the most commonly used bending technique in tube bending to achieve good precision results. There are several other bending techniques such as Ram Method, Rotary Method, Roller Method, and Compression Method. In this analysis, an experimental method was carried out by making variations of mandrel models and different mandrel ...

Experimental study on rotary draw bending of magnesium alloy extruded tubes
IOP Conference Series: Materials Science and Engineering, 2020 Abstract In this research, the rotary draw bending of magnesium alloy extruded tubes was experimentally investigated. At room temperature, circular magnesium alloy tubes were bent without cracking and wrinkling, but with defective shape.

Material modelling and springback analysis for multi-stage rotary draw bending of thin-walled tube using homogeneous anisotropic hardening model [PDF]
The aim of this paper is to compare several hardening models and to show their relevance for the prediction of springback and deformation of an asymmetric aluminium alloy tube in multi-stage rotary draw bending process. A three-dimensional finite-element

Dynamic Detection of Instability Defects in tube Rotary Draw Bending
Procedia Manufacturing, 2017 Abstract Tube rotary draw bending is commonly used to manufacture complex shaped elements in a wide range of geometries and applications. When thin-walled tubes are formed with small bending radii, the components may suffer of wrinkling at the intrados due to the critical process parameters.
