Product Details
Electro-hydraulic servo CNC press brakes are high-precision forming machines used in the sheet metal fabrication industry, employing dual-cylinder, independent electro-hydraulic servo closed-loop synchronous control. The machine utilises a closed-loop control system comprising a CNC system, electro-hydraulic servo valves and dual-sided linear encoders to drive the ram, which presses down on the upper die, causing plastic deformation of the sheet metal to achieve bending and forming operations at various angles. These machines are widely used in the batch production of precision sheet metal components.
Principle of Operation
The left and right main hydraulic cylinders are not mechanically rigidly connected; the CNC system sends control signals to the electro-hydraulic servo valves on both sides separately;
High-precision optical encoders are fitted at both ends of the ram to capture its actual position in real time and feed this data back to the control system, thereby forming a closed-loop control system.
When positional deviations occur between the left and right sides of the ram, the system rapidly adjusts the flow rate of the servo valves to dynamically correct the feed speeds of the cylinders on both sides, ensuring synchronised ram operation.
Long-panel bending operations are typically equipped with a CNC deflection compensation mechanism (V-axis), which automatically counteracts the deformation of the worktable caused by pressure, ensuring a uniform bending angle across the entire workpiece.
