Bend part

Bending

Bending is a procedure for forming a flat, sheet metal workpiece. It immediately follows cutting in the processing chain. The workpiece lies on a bottom tool with a v-shaped opening. A wedge-shaped tool (punch) presses the workpiece into the v-opening and thus bends it to the desired angle.

Bending tools

Perfect bending results thanks to the right tools. Original tools from Bystronic are capable of unleashing the full potential of the machine’s characteristics, in order to ensure that your parts are always bent with utmost precision.

Air bending

Air bending

During air bending, the upper tool presses the workpiece into the bottom tool opening, however without bottoming. The workpiece rests solely on the two edges of the bottom tool during the entire bending process. The bending angle is determined by how deep the top tool plunges into the bottom tool. Air bending permits bending at various angles without a tool change.

Dynamic crowning

Bystronic has long used dynamic crowning on the Xpert model range press brakes. This unique compensation system automatically adjusts the bow of the lower beam, during the bend. State-of-the-art dynamic crowning makes this correction in real time using the latest sensor technology. Users can therefore achieve exact, constant bending results and this even with bent parts which are longer than 3 meters.

Precision

Precision

Precision is the most important yardstick for press brakes. Slight deviations from the desired bending angle are physically unavoidable. The bending angle can either be basically inexact or can vary across the bending length. During air bending, compensation systems eliminate these errors. Bystronic uses the unique hydraulic dynamic crowning technique on its press brakes: The upper and lower beams are specifically bowed to eliminate the deformation caused by the bending process itself.
