Energy efficiency of cold roll forming process
The International Journal of Advanced Manufacturing Technology, 2012Cold roll forming is an important sheet metal forming process for the mass production of a variety of complex profiles out of a wide spectrum of materials and thicknesses. The energy efficiency of such a continuous bending process may lead to a significant reduction in energy consumption. In this paper, the energy efficiency indicator is introduced for

CAD System for Cold Roll-Forming
CIRP Annals, 1989Abstract A computerized simulation system for cold roll-forming has been developed. It is applied to various forming processes of electric resistance welded (ERW) pipes, light gauge section steels, deck plates and others. Through a series of simulations, effects of pass-schedule, geometry of roll, dimension of product and mechanical properties of ...

A simulation of cold-roll forming for elastoplastic materials
International Journal of Mechanical Sciences, 1998In our formulation, the metal sheet is considered as a thin shell, and its middle surface is described as a Coons patch depending on one geometrical parameter. Moreover, the material satisfies a constitutive rate equation in which the corotational rate of stress is used.

A simplified method for the simulation of cold-roll forming
International Journal of Mechanical Sciences, 1993A kinematical approach is proposed for predicting the optimal shape and the deformed length of a metal sheet during cold-roll forming, before the first roll stand. The middle surface of the sheet is described as a Coons patch depending on one geometrical parameter.

Emulation and Prediction of the Cold Roll Forming Force
Advanced Materials Research, 2012In order to optimize the craft parameter of cold roll forming, this paper puts forward a new method reflect the law between cold roll forming force and craft parameter. The method combines artificial neural network and finite element emulation for cold roll forming, and begins with analyzing the cold roll forming to decide the main factors that have an

Modelling of cold roll forming of steel strip
Materials Science and Technology, 2001AbstractGood roll pass design is the key to successful roll forming. To reduce forming defects and trial production costs, computer aided simulation of cold roll forming is employed. In this paper, a theoretical model, based on the updated Lagrange method of deformation mechanics and using the elastic–plastic large deformation B-spline finite strip ...

Micro-forming of aluminum alloy by cold rolling
2010In the present study, crystal aluminum alloy with fine grain was used for micro-forming. The micro-forming was tried on the melt spun Al-14mass%Si foil by cold rolling. The ability of micro-forming of a metallic alloy by cold forming was investigated. A V-shape die was used with depths of 1, 3, 5 and 10 μm. Rolling speed was 1 m/min.
