The working principle of the hydraulic bending machine is that the wire is energized to the coil, and after the electricity is energized, the pressure plate is gravitational, so as to realize the clamping of the thin plate between the pressure plate and the base. To ensure machine structure has good rigidity,vibration many hours to eliminate the internal stress.It is equipped with famous brand Estun E21 controller system,easy operate.Different molds can be used to meet the high-precision bending requirements of different workpieces. The mold of the hydraulic press brake machine has high hardness and good toughness, and can bend multi-angle workpieces.It is equipped with well-known accessories, such as rexroth vale,sunny pump,schneider electrics,siemens motor and many other components with good performance.
