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.

Multiobjective Optimization of Roll-Forming Procedure Using NSGA-II and Type-2 Fuzzy Neural Network

IEEE Transactions on Automation Science and Engineering
In this research, the effective indexes in the cold roll-forming procedure that can affect the energy utilization and required maximum torque of the forming line have been investigated and optimised using NSGA-II and type-2 fuzzy neural networks.

Computer-Aided Design and Manufacture of Rolls for Cold Roll Forming Machines

1976
The process of cold roll forming is well established and its range of application is continually widening. However, the manufacture of the rolls themselves, by manual methods in both drawing office and workshop, is a difficult and time-consuming stage in the production of cold roll forming machines.

Anisotropy in laser forming of cold-rolled stainless steel

Optical Society of America Annual Meeting, 1990
Laser forming is a new metal-forming process that makes shapes by using laser irradiation. Cold-rolled AISI 304 stainless steel sheets have been cut into square samples and tensile-test samples. The former samples, which are 0.3 mm thick, have been irradiated with the defocused beam of a 100 W carbon dioxide laser.

Numerical Simulation on the Cold Rolling Forming of Spline

2017
Finite element modeling and numerical simulation analysis of the spline cold rolling precision forming process have been carried out with software DEFORM-3D. The simulated results are compared with those obtained from the theoretical analysis.
