Hydraulic Circuit
The hydraulic circuit is the interconnected network of components in a press brake that enables precise hydraulic transmission. It includes the hydraulic pump, cylinders, valves, and reservoir, working together to generate, regulate, and direct hydraulic energy to bend metal sheets with high force and accuracy.
Energy Conversion: Transforms electrical/mechanical energy into hydraulic energy via the pump.
Force Transmission: Delivers hydraulic pressure to the ram (slide) through cylinders.
Flow Direction Control: Ensures precise timing and movement through control valves.
Pressure Regulation: Maintains safe and consistent system pressure during operation.
Energy Recovery: In modern systems, unused oil can be redirected or recovered for efficiency.
Hydraulic Pump – Generates flow; typically gear, vane, or piston type.
Hydraulic Cylinder – Converts fluid pressure into mechanical motion (moves ram).
Directional Control Valves – Direct the flow of oil to various parts.
Pressure Relief Valves – Prevent overpressure by releasing excess oil.
Flow Control Valves – Adjust the speed of cylinder movement.
Reservoir (Tank) – Stores, cools, and filters hydraulic oil.
Filters & Cooling Units – Ensure clean and thermally stable oil for system longevity.
Hydraulic Lines & Fittings – High-pressure pipes, hoses, and connectors.
Conventional Hydraulic System
Widely used, based on synchronous movement of left/right cylinders using mechanical balancing.
Electro-Hydraulic Synchronous System
Features proportional valves and linear encoders for real-time correction and parallelism.
Servo-Hydraulic System (Hybrid)
Uses servo motor-driven pump systems for energy savings and silent operation.
As a supplier of hydraulic components and assemblies for press brakes, we provide:
✅ High-precision hydraulic valves and cylinders with tight tolerances for stable bending.
✅ Custom-built circuit kits tailored to your press brake model (Y1/Y2 axis logic, etc.).
✅ Energy-efficient solutions, including servo-pump systems and closed-loop control.
✅ Leak-proof fittings and piping systems, tested under high-pressure conditions.
✅ Modular design options for easier maintenance and component replacement.
✅ Support for both OEM integration and aftermarket upgrades.
