Abstract

Process and device used for adjusting the depth of penetration of a hydraulic folding press. They allow to adjust the depth stop (3) of the pressure bed (4), without being necessary to lift the pressure bed from the workpiece. The depth stops (3) are relieved temporarily by a pressure in the cylinders acting in the opposite direction of the pressure bed (4), for example in double-acting cylinders (2) without any pressure drop on the workpiece. It allows a precision adjustment of the penetration depth in one operation. The process can be applied to folding presses having a mechanical or hydraulic travel limiting device.
