  • Hydraulic control for press brakes
    Patent number: 5433097
    Abstract: A method and apparatus for controlling the stopping position of a press brake punch is provided. Hydraulic control is provided so that the variations in punch stopping positions due to variations in manifold valve response times are minimized. A variable displacement hydraulic pump and a solenoid valve are used in conjunction with manifold valves in order to precisely stop a press brake punch. When it is desired to stop the punch, the solenoid valve is shifted and pump output begins to decrease before the manifold valves begin to shift.
