Title: Sliding frame press

Abstract: A sliding frame press utilizing a single pressure generating actuator to simultaneously apply the same uniform load to opposite sides of a workpiece. Two posts integral to sliding frame part 2 are freely and movably supported at the upper surface and within a post guide part located at both sides of frame base 5. Pressure is exerted on pressure rod 7 by the force applied at actuator 6. When the pressure applied to pressure rod 7 by actuator 6 exceeds the free weight of sliding frame part 2, a reactive force generated from pressure rod 7 operates to raise sliding frame part 2, thus simultaneously applying a uniform load to opposing sides of the workpiece located between pressure rod 7 and the lower punch 9 operatively connected to the sliding frame part 2.
