Bending becomes child’s play
… makes you an expert for any plate rolling task
No more scrap when rolling challenging shells, and fitting parts starting with the first plate in batch production thanks to BENDtronic. The revolutionary BENDtronic of HAEUSLER enables everyone, to control not only the movements of the machine but the bending result itself. The software is graphically supported, allows single-pass as well as multi-pass plate rolling and can be used for any kind of product shape like cylinders and pipes, ovals, tanks or other more complex geometries even up to S-shaped work pieces.
Round shells are typical objectives of plate rolling machine operators. This often underestimated task requires experienced operators who have a feeling for materials, machine behavior and desired geometries. BENDtronic allows operators to enter physical properties of the bending task, receive bending knowhow and execute the bending program. BENDtronic operators quickly become bending experts.
Multi Radial geometries such as ovals, cases or buckets are obviously challenging objectives for plate roll operators. However, the lucky operator who can rely on BENDtronic is also “in good shape” here. After the graphically supported definition of the desired geometry, BENDtronic calculates the machine settings and all the steps from the flat plate to the final geometry. The operator can start rolling right after the process simulation.
No waste when rolling individual parts (One-of-a-kind or small batches) thanks to BENDtronic which allows rolling workpieces that have already been rolled to a certain shape. Hand on heart – isn’t this the reality in most cases: even with the most reliable CNC software and the most experienced plate roll operator there is always the doubt that slight differences in plate properties such as thickness or yield stress will influence the bending result.
The safe bet is to approximate the final geometry, staying just a little bigger than the required final geometry with the first pass. For the second pass one just needs to measure the real geometry, enter the values into the corresponding mask of BENDtronic and roll the workpiece to the final geometry.
The sheet material model accounts for non-linear yield behavior. The computation of the stress distribution based on the Euler beam theory allows exact predictions of spring back for any plate thickness.
Machine behavior is simulated based on bending deflection of the rolls, machine stand stiffness and friction in various parts. Modeling the machine-plate interaction includes contact point modeling as well as gravitational forces acting on the plate.
Example of bending a round shape
The task is to roll a cylindrical shell (or section of a shell) in 1 single pass starting from a flat plate. BENDtronic allows you to:
