COPRA RF has been global market leader in the field of roll forming software. That is not only because we make the design process as effective as possible for producers, but also our employees constantly advance our solutions and acommodate ever changing demands from the industry.
Since modern roll formed products go through extremely long lines with additional steps like welding, embossing, bending or also Inline measurements. This means tough requirements for solutions that are merely met with good software alone. COPRA RF comprises all the experience of our long-serving employees that are not only software devolopers or engineers, but rather genuine roll forming experts.

COPRA RF covers the whole roll forming process chain and provides tailor-made software solutions for tube makers and profile manufacturers alike. It is integrated in the COPRA workflow and thus allows unlimted possibilities for process optimzation. Therefore, you can successfully conduct a simple roll tool design as well es the implementation of a complex roll forming line.
COPRA RF roll forming software provides a large number of predefined and, as required, customizable forming strategies. This makes simple roll design almost as easy as setting up complex roll forming systems.
Abstract:Cold roll forming can fabricate products with complex profiles, and its parameter optimization can achieve high quality and improved precision of products. In this paper, taking the side shield as a typical product, the cold roll forming of a complex section of stainless steel SUS301L-ST is analyzed, establishing a 3D finite element model by using the professional roll forming software COPRA. We propose a floating roll device for complex sections with asymmetry and large depth. We use an orthogonal experiment to obtain the inter-distance between rolls, friction coefficients, the diameter increments, and line velocities to investigate the effects on the maximum longitudinal strain of the edge. Results show that the diameter increment has the greatest influence on the maximum strain, and its increases can reduce the strain. The inter-distance value needs a suitable range. A small value is not conducive to the release of elastic deformation, while a large value will cause unexpected displacement and increase the cost. The friction coefficient increases; although it helps to reduce the strain, it will cause scratches and other defects on the stainless steel. The increase in velocity increases the strain. We derive the optimal parameters for the complex section, providing a theoretical basis for practical production.Keywords: roll forming; finite element analysis; stainless steel; parameter optimization 2ff7e9595c
