F3 - COPRA® FEA RF Wire Rolling

Analysis Software

In addition to the purely geometric aspect, there are other factors that play a by no means negligible role. These include the fact that the material lengthens when it is formed, and can be very difficult to force into the border regions.

Forming of a Polyline

Large deformations produce local strain hardening, as a result of which the material can become brittle and thus fissured.

 The COPRA® RF Wire Rolling solution for wire rolling pursues three objectives:

  • Interactive modeling of the rolling steps based on available experience: the designer draws the progressive steps and can put the areas into the required percentage ratio with the aid of COPRA® RF Wire Rolling. 

  • Automatic layout of the forming steps by specifying the start and end cross-section. Here it is possible to specify the degree of deformation and the estimated reduction of the cross-section.

  • Verification of the design by COPRA® FEA RF Wire Rolling (finite element simulation). Forming is computed based on roller geometry and the start cross-section. The actual shape to be expected can be verified in the individual steps and the change in the material examined.
