Long-side Benders FLN / FLW
Product Details
Material-friendly Part Flow
Pivatic uses sheet metal bending technology where the bending process is carried out using folding technology which is most suitable for sensitive materials. The material moves between stations without being scratched or dented.
The bending process is efficient because the wing folding machines bend negative and positive angles set for each edge of the work piece, and the sides and the ends are bent at the same time. Also, there is no wear on tooling. The bending tools and the hold down tools are all engineered in-house according to the geometry of your parts, to minimize or eliminate the need for tool changes.
Media
The process is more flexible as negative and positive angles, dimensions, and sequences are all programmable. PivaBend processes different work pieces one-off and as large batches. The automated tool change system eliminates manual setups between batches. It is possible to integrate PivaBend to other processes such as spot welding and clinching.
The first PivaBend wing forming machine was launched to market in 1989. It has been further developed without changing the working principles, which now pays off with high machine uptime. A Siemens line controller and standard components secure the reliability.
Material Specifications
PivaBend folding machines are designed for steel thickness up to 2 mm (0.078”), and applied for blank size up to 3 000 x 1 500 mm (120 x 59”). Pivatic also provides MPB benders which are capable of bending up to 4 mm (0.157”) material thickness and blank lengths up to 8 000 mm (314”). PivaBend is suitable for materials with sensitive surfaces such as pre-painted stainless steel and aluminum.
Long-side Benders FLN / FLW
The long-side sheet metal benders FLN (Folding Long Narrow) and FLW (Folding Long Wide) are designed to bend either only upwards or upwards and downwards. They are always controlled with the CNC. Benders are servo electric for thin material and hydraulic for heavy-duty applications. They are selected according to the type of material, material thickness, and main dimensions of the work pieces.
PivaBend FLN consists of two stationary bending machines. It has CNC feeders for transporting and positioning of the work piece. This layout allows two blanks to be bent at the same time. To ensure correct positioning, blanks are positioned against corner notches prior to the bending cycle. PivaBend FLW consists of a separate positioning device, two traversing bending machines and CNC feeders for transportation of blanks. Both sides are bent simultaneously for reduced cycle time. Blanks are referenced prior to bending leading the tolerances to the first bend.
