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.

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

Numerical simulation of cold rolling involute spline forming

2009 International Conference on Mechatronics and Automation, 2009
Using explicit central difference algorithm, the numerical simulation of cold rolling involute spline is accomplished by finite element method. The metal flowing law and the stress and strain field of involute spline are presented. Comparing and contrasting simulation results with experimental results, some conclutions can be obtained as follow.

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.

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 ...

Numerical Simulation of Cold Roll Forming Process

2005
Cold roll-forming process of a U profile is modelled and simulated. The simulation is based on a 3D finite element analysis with the help of the home made Metafor code. The prediction on dimensions and deformed shape of the cold roll-formed sheet is in good agreement with the experimental results.

Emulation and Prediction of the Cold Roll Forming Force

Advanced Materials Research, 2012
In 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, 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 ...
