The return motion of the pressure box is controlled by the lifting piston rod (9), which slides inside the lifting cylinder, while the displacement cylinder passively follows the pressure box during the return stroke. The lifting piston rod has a mechanical stroke limitation (15), which limits both forward...

... of cylinder. However, single-acting cylinders require a method of returning. If the cylinder is extending upward, such as in a die cushion or in a pushup press, gravity may retract the rod. In small shop presses, spring-return cylinders are employed ( Fig. 12.3b ). It is also common that a single-acting...
