Dynamic muting for greater productivity
The control system PSSuniversal PLC performs two central tasks: monitoring of dynamic muting and speed profile during the braking process. The functions are available as blocks in the software platform PAS4000. As a result, it's possible to approach the plate for longer at high speed during the bending process. So the time that the upper tool travels at reduced speed is reduced to a minimum.
Safe press braking with large tools
Some tools used on press brakes cannot be safeguarded using a conventional solution due to their size. In accordance with the standard EN 12622, however, each bending line must be safeguarded by a protected field min. 15 mm in advance on the operator side. A requirement for complying with this normative specification is that the tool is situated completely within the protection system's field of vision. The protection systems PSENvip can help in this case.
With the special tools function certified by TÜV Nord, various tool sizes are now classified for the protection systems PSENvip. In tool class 1, protection is in accordance with the standard. However the camera image for tool classes 2 and 3 can only partially identify the tool in view of its size.
The camera-based protection systems PSENvip can also safely monitor large tool shapes: by means of raising the switchover point or changing the speed when lowering down onto the sheet metal. They check the tool contour and assign it to tool class 1, 2 or 3. The established class is communicated to the controller, which then issues enables for class 2 and 3 tools. The switchover points defined by the risk analysis are also monitored.
