C-frame mechanical eccentric press, PE-4 315, HIDROGARNE

Hidrogarne PE Series are C-frame mechanical eccentric presses suitable for a wide range of applications such as punching, stamping, blanking and deep drawing. The PE Series combines high precision, structural rigidity and reliability for serial and mass production.

The press frames are manufactured from S355JR steel and undergo stress relieving and precision machining after welding, ensuring perfect parallelism and accuracy.

Structure and precision:

• Welded and stabilized frame made of S355JR steel.
• Post-weld machining for maximum accuracy.
• CAE and finite element method used in design.
• High rigidity and long service life.
• Connecting rod made of high-strength forged steel with alloyed bushings.

Lubrication system:

• Centralized automatic lubrication system.
• Programmable progressive oil distribution.
• Reduced wear and extended component lifespan.

Overload protection and compensation:

• Hydraulic overload protection system.
• Safety valve releases oil if nominal force is exceeded.
• Slide and die weight compensation by two pneumatic cylinders.

Clutch and brake system:

• Electro-pneumatic clutch-brake unit.
• Double safety solenoid valve.
• Crossflow safety system.
• Pneumatic system with air tank, FRL unit, pressure switch and safety valve.

Electrical equipment and safety:

• Control panel with manual, semi-automatic and automatic modes.
• Redundant and self-monitored electrical and hydraulic actuators.
• Additional PLC for control and safety.
• Low-voltage two-hand control and foot pedal.
• Side safety guards with opening capability.
• Category IV safety light curtains on the working area sides.
• Compliance with CE safety standards.
