  • Patent number: 4070896
    Abstract: A press brake having improved ram leveling adjustment is disclosed. The press brake is preferably one having a hydraulic-mechanical power actuator for advancing and returning the ram. The power actuator includes a pair of bell cranks pivotally supported on an upright frame by a pair of horizontally spaced pivots, a hydraulic piston and cylinder motor for oscillating one of the bell cranks, and a link connecting like arms of the bell crank for causing parallel motion of the bell cranks. Leveling adjustment of the ram is obtained by providing horizontally spaced parallel links which are independently adjustable in length to interconnect the ram and second like arms of the bell cranks. An independently controlled reversible motor is operatively associated with each adjustable link for selectively lengthening or shortening the link, and an indicator is associated with each link to indicate position adjustment of each link.
