Effect of Cooling on Bending Angle and Microstructure in Laser Tube Bending with Circumferential Scanning
Laser tube bending is a flexible forming process. Two irradiation methods of axial and circumferential scanning are generally used to form metal tubes. The two most important disadvantages of circumferential scanning are its lower bending angle and the time interval required between each scan for cooling purpose. In this research, a novel cooling strategy during laser tube bending with circumfe...
متن کاملThe Effect of Normal Anisotropy on Thin-Walled Tube Bending
Thin-walled tube bending has common applications in the automobile and aerospace industries. The rotary-draw-bending method is a complex physical process with multi-factor interactive effects and is one of the advanced tube forming processes with high efficiency, high forming precision, low consumption and good flexibility for bending angle changes. However, it may cause a wrinkling phenomenon,...
متن کاملAnalysis of the Rotary-draw Bending Process for Thin-walled Rectangular Aluminum Tube
The Rotary-Draw Bending (RDB) process is a distinguished process employed for the precision cold bending of a hollow tube with small radius bends using Numerical Control (NC) machines. This research presents an analytical model based on the power law hardening model for the RDB processing of rectangular thin tubes. Based on the constraints of the tube in the dies and its thinness, the plane str...
متن کاملNumerical and experimental investigation of laser induced tube bending
Mechanisms of the process are examined to better understand the deformation characteristics such as slightly protruded shape at the intrados, wall thickness variation, cross-section ovalization, bending radius, and asymmetry. A finite element model is developed and validated by experimental observations. Factors important to characteristics of deformation are experimentally and numerically inve...
متن کاملCriteria for selecting innovative technologies for maritime transhipment facilities
The significant cargo volumes transferred by sea, in combination with the increased technological and operational requirements that international competition imposes, lead to the continuous upgrade of infrastructure and equipment of modern port terminals. Within this framework, a number of new technologies for the transhipment of unitised cargo have been developed and are available in the marke...
