Abstract
Device for the automatic change of strokes in presses, which being applied in those that have an eccentric drive shaft of the carriage, is characterized in that it has at least one eccentric area of the shaft where a bushing is located that can rotate and equipped with an eccentric mechanism on part of its outer circular surface at one of its ends, while at its other end it has an external toothing in linear correspondence with that practiced on another axial sleeve fixed on the same eccentric area of the shaft and fixed with a key; the toothing of both axial bushings being fixed in the same eccentric area of the shaft and fixed with a key; the toothing of both bushes being engaged with the internal toothing of a locking part, which has a central area of its dentate periphery provided with a smooth circular recess and in a length equivalent to that of the tooth of the bushing keyed to the shaft, which allows the relative unlocking of both ferrules when displaced at will and axially the blocking piece by two diametrically opposed discs fixed to the ends of both rods belonging to a pneumatic cylinder when the disks are fitted in a peripheral central notch of the blocking piece, existing corresponding microswitches connected to one of the discs and rods, with optical signaling on an electronic panel, which accuse the blocking and release of the eccentricity-based bushing; also disposing, in a non-eccentric area of the shaft, a circular piece concentric to it, located in contact with the front face of the bushing provided with eccentricity, which has a radial and frontal notch on this same side of the bushing, in which it remains guided a prismatic piece joined to the bushing by means of a screw, existing in a point of the periphery of this circular piece, a hole that when confronted with an electronic detector fixed to the bed registers in the panel the eccentric position of the shaft, in its neutral position higher; also having a third bushing fixed to pressure, located on the free end of the eccentric shaft, where it has no eccentricity, on whose periphery are arranged a series of holes whose position in its turn, is captured by an electronic detector, fixed to the bed, when confronted with it, each one of these orifices corresponding to a different and predetermined jump of career, signaled in an electronic reading visualizer, making the automatic change of stroke by means of a gearmotor group that produces the eccentric axis rotation, while the cap remain without rotation, until the desired stroke is adjusted.
