Design and implementation of a CAD system for cold roll forming

Computers & Graphics, 1986
Abstract This paper discusses the motivations behind the successful in-house development of a CAD system for toolage design of the cold roll forming process. Emphasis is placed on the need for on-going research efforts in providing information for critical evaluation of design alternatives.

A simplified method for the simulation of cold-roll forming

International Journal of Mechanical Sciences, 1993
A 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.

Micro-forming of aluminum alloy by cold rolling

2010
In 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.

The prediction of deformation length in cold roll-forming

Journal of Mechanical Working Technology, 1984
Abstract Cold roll-forming is a process of forming metal from sheet, strip or coiled stock into shapes of essentially uniform cross-section by feeding the strips through successive pairs of rolls arranged in tandem. The deformation in cold roll-forming is quite complex and due to this inherent complexity of the process, the roll design and other ...

Modelling of cold roll forming of steel strip

Materials Science and Technology, 2001
AbstractGood 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 ...

Computer-Integrated Manufacture for Cold Roll Forming

1986
Computer-integrated manufacture has brought about great advances in manufacturing technology and its contribution is world-wide. Cold roll forming, and in particular the design and manufacture of form-rolls, the special tooling used in the forming process, is but one such area where computer-integrated manufacture can make a positive contribution. This

Finite Element Modelling of Cold Roll Forming

Cold Roll Forming is the process of running a flat sheet of material through a series of rollers, known as stands, to produce three - dimensional sections. This thesis aims to produce a Finite Element Model Simulation of Cold-Roll Forming process, particularly to the application LiteSteel Beam™ and 120 Nominal Bore Schedule 40 pipe as produced by ...

Software Architecture for Cold Roll-forming Design and Simulation

2009 WRI World Congress on Software Engineering, 2009
As a result of analysis of the technical difficulties of cold roll-forming and the requirements of a collaborative design system for cold roll-forming, the physical four-tier structure of the cold roll-forming system is proposed. And then the architecture of a multi-agent based collaborative design system is introduced, with defining all the agents of ...
