Roll Tools

Roll forming 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 roll formers 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..

Next exhibition:
Visit us at Blechexpo Exhibition Nov. 07-11, 2017 in Stuttgart/Germany: Hall 5 Stand 5500 (Joined stand with DYNAmore, the reseller of the FEA system LS-DYNA) Be one of the first who learns to know the features of the new release!
New: Separate calculation method
For special purposes e.g. stiffening corrugations or other applications, when deep drawing effects occur, a separate calculation method of the developed length can be assigned to each profile arc element. The user can select between a standard method, such as Oehler, DIN, centerline, or define user methods that can be equipped with empirical corrections. The new dialog window gives an overview of the existing calculation methods, enables defining user methods, and applying the methods to the profile's arc elements. In this window, the position of the neutral line is shown as a graph dependent on ri/s (ratio inner radius/sheet thickness). More..
New: Chamfers for threading:
For the FEA simulation, the sheet lead end must be threaded correctly into the roller stands. In addition to the guiding function a new feature is available: The sheet lead edges can be chamfered in width and in thickness direction. More..
Element type SOLID alternatively to element type SHELL
In order to meet varying demands, the FEA system LS-DYNA allows selecting between shell and solid elements. Shell elements are well suited for pure bending; the calculation is quick and effective. However, limits exist if massive forming occurs. In this case solid elements are more advantageous, the calculation, however, needs more time. The designer can select between shell and solid elements dependent on his application. The software creates the simulation model for the FEA system LS-DYNA automatically. In case of solid model, selection among 2, 4, 6, or more elements in sheet thickness direction is possible. More..
Interface to SolidEdge and BricsCAD
The goal of the software development has been: The new PROFIL user should continue using his preferred CAD system. For this reason PROFIL was designed to work closely with any CAD system. A new feature is the comfortable ActiveX interface to SolidEdge and BricsCAD. More..
Postprocessor for LS-DYNA
The postprocessor helps to evaluate the result of the FEA simulation. It opens the LS-DYNA output files directly and shows the simulation result on the PROFIL screen. Graphs show the transversal and longitudinal stress, the strain, and the sheet thickness reduction as a function of the sheet position in the machine. Sectional views of the sheet within the rolls, at any machine position, or after leaving the machine are created by key-press. The rolls can be inserted (as 2D cross section or as 3D solids alternatively) in order to check the position of the sheet within the roll tools. Inserting the designed flower pattern enables target/actual comparison. More..
Lead (Strip Tension)
It's a common practice to keep the strip under tension by gradually increasing the roll pitch diameters. It prevents vertical buckling and reduces the spring back between the stands. After choosing the increment PROFIL inserts the appropriate working diameters in all stands. More..
FEA simulation of the roll forming process with LS-DYNA
After designing roll forming tools for a new profile the designer wants to verify if the roll tools are able to produce the profile cross-section within the given allowances. The FEA (Finite-Element-Analysis) simulation of the roll forming process enables the designer to validate and optimize his roll form design at an early stage. New is the interface to the FEA system LS-DYNA. After designing the roll tools the files with the FEA model are created by key-press. In case the sheet is pre-punched, bore holes and cut-outs can be defined in a CAD drawing easily. After roll tool modification, the FEA simulation can be restarted at any roll forming stand. More..
Expanded Undo /Redo functions:
The function name of the next step is shown and the count of steps can be preset by the user. Henceforward, the user does not need to guess anymore, which function will be reversed next; the software shows it beforehand. More..
New Functions For Flexible Design
Varying profile width, varying strip width, varying sheet thickness in the same roll forming machine, is this possible? It's a hard work to design the roll tools in such a flexible way that they are able to consider varying product properties without or with little set-up time and effort only. The developers of the roll form design software had some good ideas how to make the designer's work easier and clearer. New functions just like modifying strip width, modifying sheet thickness, and a new kind of replaceable spacers make it possible to design the roll tools flexibly for varying product properties. More..
Spacer Rolls as Objects
The new kind of spacer rolls are handled as forming roll objects. They can be selected by mouse-click, can be dimensioned and modified, and they are named dependent on special number keys. If needed, spacer rolls are split into shims automatically. More..
Multi Axles Machine
The automotive industry and also other applications require more and more complex roll formed profiles. In order to form such profiles on a roll forming machine, it often is necessary to have additional side axles with inclined angles that plunge into the open cross-section. This makes it more easy to form the inner radii precisely, that are not accessible for horizontal top rolls. For this purpose additional side axles with arbitrary inclination angle can be created in the machine window. More..
Machine Data
are handled in the profile project completely, and are saved into the project file. The machine file in its previous form now is used for machine data exchange between different projects. In the machine window, machine design is fully interactive. More..
Shaped Tubes
are tubes with any cross-section that are formed from a welded tube by using calibrating stands (Turk's Heads). In this process the initial shape should come as close as possible to the final shape. If the shaped tube has nearly a square form (with same width and height), it should be formed from a welded round tube. If the shaped tube is either quite large and flat or quite high and narrow, an ellipse is the appropriate initial shape. Also calibrating by keeping the cross-section unchanged is often used. 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..
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..
Folding the band edge
When a folded band edge with inner radius zero is formed to a hem, the material´s spring back causes a considerable problem. The sheet surfaces should touch closely and should not spring up. 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 points 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 practice, a linear function with fillet radii is often used or a cosine function. 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..
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..
Profile Catalogue
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 roll formed parts. More..
Profile Stress Analysis (PSA) is the second step of the three step quality management concept. The sheet metal strip is divided into small shell elements and the geometrical deformation while passing through the roll forming 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..
PROFIL Roll Stock Management
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..
Virtual Roll Forming 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 roll form 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 systems LS-DYNA. More..
