ePRAX modular - Control for press brakes

Product description

The ePRAX modular speed-controlled drive is a compact servo drive that controls the cylinder movements of the ram in CNC press brakes. Changes in cylinder rate and position are managed by means of a controlled servomotor separately for each cylinder through combination with dedicated drive controllers. The return stroke is implemented according to the bending task to be performed and the expansion stage of the ePRAX modular with the aid of temporarily stored hydraulic energy. This allows high dynamism and short cycles. The control system has been verified for its intended application in hydraulic press brakes as per DIN EN 12622 certification.

Long oil lines are not required when mounting in the press brake, as the system is mounted directly on the cylinders. The optionally available tank module can be flexibly positioned on the press brake, enabling optimal use of the available installation space. The ePRAX modular control system enables the implementation of press brakes with pressing forces of up to 4,000 kN (400 t), and therefore provides a powerful solution to handle demanding bending applications in sheet metal processing.

Features and advantages

• The anti-cavitation valves (normally closed version) are integrated into the manifold, which therefore simplifies the cylinder interface
• Energy-efficient
• No limitation on machine length
• Optionally available modules for tool clamping offer additional functionality and customization options

Intended applications

• Press brakes
