Automating the Design of Cold Roll Forming Roll Sets
Key Engineering Materials, 2009The 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 prediction of roll load in cold roll-forming
Journal of Mechanical Working Technology, 1987Abstract Due to the inherent complexity of the cold roll-forming process, machine design procedures have remained highly empirical. There is little information available on the calculation of roll load, though a prior knowledge of this load is essential for the optimum design of the roll stands and the smooth forming of the strip.

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

Numerical simulation of cold roll-forming processes
Journal of Materials Processing Technology, 20083D finite element analysis is employed to simulate a cold roll-forming process. Numerical results of longitudinal strains and displacement trajectories are compared with experimental results available in the literature. Through a parametrical study, significant impacts of the yield limit and the work-hardening exponent on the product quality are ...

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 ...

The optimisation of cold rolled formed products
Thin-Walled Structures, 1997The 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, 2009This 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.
