Applications: Suitable for various applications such as rimming, caulking, seaming, assembling, keying, blanking, marking, bending, and riveting.
Technical Specifications: Pneumatic presses operate with filtered and lubricated compressed air at 3 to 6 bar and temperatures from -10 to +50°C. The PRNA series offers models with varying active sections, theoretical power, maximum stroke, and cycle consumption.
Power Units CM S44: Used in all GPA hydropneumatic presses, these units offer high speed, low air consumption, and a working stroke up to 30 mm. They feature a patented hydraulic circuit for easy maintenance.
Control System Overview: The control system includes a PLC and touch screen operator panel with cycle instructions and alarm diagnostics. It allows for pressing time and table rest time adjustments and includes counters for batch end stops and maintenance.
Optional Features: Optional controls include position, pressure, and force transducers. Additional features include integrated frames with rotary tables, hydropneumatic presses with up to 320 kN force, and photoelectric barriers for press control.
Force-Stroke Control System: Applicable to all GPA hydropneumatic presses, it includes an electrical control board, graphical interface, load cell, position transducer, and software for force control, supporting eight programs and providing work statistics.
Accessories: Accessories include support benches with electrical height adjustment, side shields, tools and dies, and various adjustment and control valves.
Additional Accessories: Available separately are proximity switches, magnetic sensors, high-pressure gauges, digital pressure switches, and guiding groups for load cells.
