摘要： A method of operating a press designed to eliminate fluctuations of the pressing force in a press. The maximum actual value of the stroke's pressing force is averaged over n strokes. The average value is compared with a desired value, and when there is a deviation, a position adjustment in the press is triggered by means of a controller. An example of the press position adjustment is a displacement of the axis of the slide.

摘要： Apparatus for changing the operating or work stroke of a punch press with a double eccentric for the mounting of a drive crank, said double eccentric being arranged upon a drive shaft and consisting of an inner eccentric and an outer eccentric sleeve or bushing. A locking pin guided in a radial bore of the inner eccentric at one end cooperates by means of teeth with internal teeth of the eccentric sleeve and at the other end is springloaded. A central adjustment spindle cooperates with the locking pin, and due to rotation of the adjustment spindle the locking pin can be displaced against the spring-load out of engagement with the internal teeth of the eccentric sleeve. There is also provided an axially displaceable sleeve or bushing which surrounds the adjustment spindle and cooperates with a slotted plate spring which in its stressed condition connects the inner eccentric by fixedly clamping same with a drive element. The inner eccentric, when the locking pin is inactivated, is rotatable with regard to the fixedly retained eccentric sleeve and therefore the eccentricity of the double eccentric and the drive stroke of the punch press is adjustable.

摘要： A rotary ring (34) formed such that an outer circumference is eccentric with respect to an inner circumference is provided to an outer circumference of an eccentric drum (333) of an eccentric shaft (33). An adjustment ring (41) formed such that an outer circumference is eccentric with respect to an inner circumference is provided to the outer circumference of the rotary ring (34), and a slide (5) is mounted to the outer circumference of the adjustment ring (41). Since the slide (5) and a slide drive unit (30) are arranged to be superposed substantially at the same height, a distance between the slide drive unit (30) and a lower end of the slide (5) can be reduced and the entire height of a servo press (1) can be reduced. In addition, since the height position of the slide (5) can be finely adjusted by rotating the adjustment ring (41), a press working can be performed with high accuracy.

摘要： An adjustment stroke connection for a mechanical press includes an eccentric bushing disposed within a press connection member and an eccentric crankshaft member disposed within the eccentric bushing. A rotatable crankshaft is connected to the eccentric member. A mechanism is provided for connecting the eccentric bushing with the press connection member in a manner that prevents rotation therebetween and concurrently permits rotation of the eccentric member relative to the eccentric bushing. When the mechanism is activated, driving rotation of the crankshaft produces a press stroke adjustment. A torque actuator delivers equal driving torque to plural eccentric crankshaft members to enable minimization of relative bushing angle slip. Suitable control of the bushing angle and slide position crank angle during bushing expansion and contraction also minimizes relative bushing angle slip.

摘要： A mechanical press having a variable drive arrangement. The press includes a main gear which drives a crankshaft. The drive altering mechanism includes a two piece crown with the main gear connected to the upper crown and the crankshaft connected to the lower crown. Movement of one piece of the crown relative to the other varies the distance between the crankshaft center line and the main gear center line, thereby altering the drive mechanism of the mechanical press and the velocity curve of the press slide.
