Rollforming is a continuous bending operation in which sheet or strip metal is gradually formed in tandem sets of rollers until the desired cross-sectional configuration is obtained. Roll forming is ideal for producing parts with long lengths or in large quantities. |

PROFIL is the roll form design software for every manufacturer of cold roll-formed profiles or seamed tubes from sheet metal and for designers of rollformers and tube mills. PROFIL enables quicker working and cost reductions in planning, design, calculation and drawing of the profile, the flower pattern (bending steps) and the roll tooling. More.. Working with PROFIL is like working with a CAD system: The drawing of the profile, the flower pattern or the roll tools is permanently displayed on the screen. More.. |

3D Models in STEP Format
CAD neutrality has always been an important goal for the development of the PROFIL concept. The user should have no restrictions in choosing the right CAD system, but he should use the CAD system of his own needs in combination with PROFIL. This goal is now achieved also in the 3D field by the new STEP interface. The 3D model of the profile pass and the roll tools can be exported in a STEP file in accordance with DIN ISO 10303. More.. |

3D Models in CAD
creates the 3D model of the current stand or of all stands of the whole roll forming line or tube forming line. The model is transferred to AutoCAD or SolidWorks via the ActiveX interface. More.. |
Trapezoidal Profile Forming
When wide sheet metal strips are roll formed to a trapezoidal profile, the course of the band edge has a crucial influence on the quality of the product. On the one hand the course must be as short as possible in order to form the band edge elastically only. The shortest connection between two point is the straight line - but the band edge is creased both at the machine entrance and exit. This is why the second important point of view for choosing the right band edge course is the tangential connection at entrance and exit. In practise, a linear function with fillet radii is often used or a cosine function. More.. |

Folding the band edge
When a folded band edge with inner radius zero is formed, the material’s spring back causes a considerable problem. The sheet surfaces should touch closely and should not spring up. More.. |
Automatic Creation Of Assembly Plan
After designing the roll tools for a new roll formed profile the production drawings still have to be created. A Roll Assembly Plan for each roll formed stand is necessary that shows the mounted rolls and the separated rolls with dimensioning in addition. A prepared Drawing Template from a DXF file is opened and the stand drawing is created in the center automatically. Then the rolls just can be picked up by mouse-click and copied or moved to another position. More.. |

Automatic Flower Creation
speeds up the design for recurring types of profiles substantially. The know-how is taken from a knowledge base that increases more and more as the system is used. Thus PROFIL has become an expert system. More.. |
Profile Stress Analysis (PSA)
is the second step of the three step quality management concept. The sheet metal strip is devided into small shell elements and the geometrical deformation while passing through the roll foming machine is calculated. From it the strain and stress in the whole profile is obtained and displayed by colors. Important e.g. if edges are folded and the folds are bent, this means when the maximal stress is not at the band edge. More..

While dealing with an inquiry the designer needs calculation data from similar profiles that are produced in the past. Designing new roll tools should consider experience from earlier projects. The profile catalogue gives a quick overview of all produced rollformed parts. More.. |
Virtual Rollforming Machine (VRM)
is the third step of the quality management concept. The FEA simulation of the roll forming process enables the designer to validate and optimize his rollform design at an early stage before the rolls are manufactured to ensure that the final product meets the particular needs. To proceed this very precise calculation of the stress and the longitudinal deformation within the whole profile, an interface has been provided to the leading FEA system ABAQUS/Explicit. More..

The designer of cold roll-formed profiles wants to re-use rolls from older projects for saving money. To find suited rolls for his new project by using search filters, he needs the roll stock management. More.. |
On 26-May-2009 the seminar Sheet Metal Rollforming: Today's State of Technology and Future Trends took place at the Institute for Forming Technologies in Lüdenscheid/Germany. Topics have been roll tool design methods, selection of sheet and tool materials, and roll forming machine concepts. In the course of this seminar Dipl.-Ing. Roland Brandegger held the lecture Less Expensive and Safer Designing of Cold Rolled Profiles and Roll Tools. More..
