Automating the Design of Cold Roll Forming Roll Sets

Key Engineering Materials, 2009
The design of cold roll forming roll tools, roll geometry and the number of tool sets, can typically be referred to as experiential design. Within a multi-occupant design office there will normally, for the same sectional profile, be as many different designs as there are designers.

The optimisation of cold rolled formed products

Thin-Walled Structures, 1997
The design, development and analysis of a new cold roll formed product is presented. The objective of this exercise is to produce an economic and efficient profile which incorporates the basic C shape, with additional enhancements to improve its structural performance. A new sectional properties computer program was employed to analyse the profile. The

Prediction of Roll Profile Wear in the Cold Roll Forming Process

Key Engineering Materials, 2009
This paper presents a model for prediction of forming roll profile wear during the cold roll forming process. The method is based on contact pressure distribution, geometrical description of the initial forming roll profile and NURBS representation of the contact area.

Development in Cad for Cold Roll Forming

1986
In order to estimate the number of roll passes necessary to form the light gage steels for general structure, relation between the shape factor and the number of roll passes for various sections is investigated by arranging the data collected from several companies.

Simulation of the cold-roll forming of circular tubes

Journal of Materials Processing Technology, 1999
Abstract The approach developed in a previous paper for the simulation of the cold-roll forming of elasto-plastic materials is applied here for circular tubes. The main idea is to consider the sheet to be transformed as a thin shell and its middle surface as a Coons patch. Since the strains and rotations are finite, the material is supposed to follow

Energy efficiency of cold roll forming process

The International Journal of Advanced Manufacturing Technology, 2012
Cold 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, 1989
Abstract 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, 1998
In 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.
