Study on the influence of mandrel type on copper tube rotary draw bending

International Journal of Materials and Product Technology, 2008
The process of rotary draw bending is a versatile, cost-effective and precise method for thin-walled copper Air Conditioning and Refrigeration (ACR) tube. Requested in industrial application for ACR tube, the wall thinning and the fattening of the cross-section are two major formability assessment factors.

Optimization of an asymmetric thin-walled tube in rotary draw bending process

AIP Conference Proceedings, 2013
The rotary draw bending is one of the advanced thin-walled tube forming processes with high efficiency, low consumption and good flexibility in several industries such as automotive, aerospace and shipping. However it may cause undesirable deformations such as over-thinning and ovalization, which bring the weakening of the strength and difficulties in ...

Tube geometry prediction in rotary draw bending process using Random Forest regression

at - Automatisierungstechnik
Abstract In this study, we introduce a data-driven learning model for predicting the arc geometry of bent steel tubes in rotary draw bending processes, through the use of data from finite element simulations. In 162 simulations, machine tool forces, movements, and the resulting tube geometry data were collected based on pre-defined ...
