Abstract: A method for the control of a ram movement and ram forces of multi-point servo hybrid presses, where the positions, speeds and forces to drive the ram can be controlled independently of each other by the servo motor, which is assigned to each pressure point or each group of pressure points, for the main drive for the ram movement in the main function and the hydraulic pressure cushions, which are separately assigned to each pressure point of the ram, in an auxiliary function, to influence process-induced position and force settings of the ram in a combinatory interaction to achieve an active control of draw depth and tilt.

Abstract: A stamping press for stamping a round blank. A ram movable in a stroke direction and in an opposite return stroke direction carries a first stamping tool. A second stamping tool and a stamping ring are supported on a press framework. The stamping tools and a stamping opening formed by the stamping ring are aligned along a working axis. An ejector device serves to eject a stamped round blank from the ring opening. It comprises an ejector pin supported on an actuating device that is movably coupled with the ram. During a return stroke of the ram the ejector pin can apply a force on the second stamping tool in order to press the round blank out of the stamping ring. In a ram movement in the stroke direction the actuating device departs from the second stamping tool and no ejector pin force is applied on the second stamping tool.

The first and second ends are moved such that a laser beam generated by the laser cutting device is directed towards a gap formed between the first and second ends and extending in the y-direction. In order to avoid adhesions to an underside of the sheet metal strip, at least one support strip and/or the dust discharge shaft is provided with a ventilation device for ventilating the gap.

Abstract: The invention relates to a press drive for a press or a press having a press drive. The invention also relates to a method for controlling the press drive by means of a control unit. The press drive is used for moving a ram of the press in a stroke direction H between an upper return point OT and a lower return point UT. It comprises a knee lever gear having a first lever and a second lever. A connecting rod engages on the knee lever of the two levers and is connected on the other end to an eccentric of an eccentric drive. The control unit can drive the eccentric drive in a first operating mode B1 or a second operating mode B2 or, in particular, also a third operating mode B3. In the first and the second operating modes B1, B2, the eccentric oscillates in a respectively different angle region W1, W2 about a rotation axis D of the eccentric drive, thus resulting in different force and movement states of the ram in both operating modes.

Abstract: A hydraulic drawing cushion (17) for a drawing press (10) includes at least one hydraulic cylinder (21) comprising a piston rod (27) that causes a total force (G) to act on the metal sheet holding ring (20). The hydraulic cylinder (21) comprises a hydraulic work circuit (37) to generate a hydraulic work force (A) in a work direction (Z) to act on a ring part (28) to which a force can be applied on both sides. Independently, a spring force (F) acts on the piston (26). The spring force (F) is neither controlled nor adjusted, but is preset. Preferably, the spring force (F) is exclusively a function of the position or location of the piston (26) relative to the cylinder housing (25). The total force (G) acting on the piston (26) results from the addition of the vectors of the work force (A) and the spring force (F).

Abstract: A method of using data on the force flow in a press for the operation of a plunger, wherein the loads of the parts involved in the force flow can differ as a result of eccentrically operating forces, in such a way that the data about the respectively acting forces that, in accordance with Hooke's law, cause an extension or compression of a movement of the parts involved in the force flow, is measured and evaluated in relation to a drive device and a position of the plunger, whereupon a skewed position of the plunger is permitted or a skewed position of the plunger is counteracted or a skewed position of the plunger is set during operation of the press.

Abstract: A transport device for the transport of workpieces in a workpiece transport direction in a press, which has a carrier rail, which is mounted, via a lifting carriage and a rocker rotatably mounted on the lifting carriage, on a vertically running upright of the press.

Abstract: The invention relates to an arrangement (20) to transport a round blank ring (30) made from plastic from a receiving location (35) to an assembly station (90). A every point in time, the orientation and the position of the round blank ring (30) are predefined, at least within a tolerance range. To execute a movement from top to bottom in a height direction (H), it is possible to use a feed device (34) with a motor-driven conveying unit (58). This conveying unit (58) moves one or more round blank rings (30) in a positively guided manner downward in the height direction (H) to a delivery location (36). At every point in time as this is done, the orientation of the round blank ring relative to the height direction (H) is defined, at least within a predefined tolerance range.

Abstract: The invention refers to a method and an apparatus (20) for manufacturing of a prismatic unilaterally open battery cell container (21). First an extruded container (41) is formed from a slug (38) by extrusion. The slug (38) consists of a uniform material. The extruded container (41) is then formed by a first ironing in a first ironing station (25) and by a second ironing in a second ironing station (28). During ironing the container is moved by a respective ironing ram (26, 29) only partly through an associated die tool (27, 30) and is reversed when reaching a reversal point (U). After the second ironing a remaining edge (82) of the obtained intermediate container (77) is separated, thereby the battery cell container (21) is obtained.

Abstract: A press and a process for operating it, has an upper tool and a lower tool for shaping a workpiece and a work unit including a press drive and/or a drawing device, is controllable by a controller, to perform the shaping process. The controller outputs, to the work unit, press process values, which define the sequence of events of the shaping process. Workpiece parameters characterize, for example, the material and/or the shape and/or at least one dimension and/or quality of the workpiece, which still has to be shaped or has already been shaped. The controller is assigned a composition matrix which contains, for each defined workpiece parameter and for each defined press process value, an individually changeable function, to describe the relationship between every one of the defined workpiece parameters and the defined press process values. This composition matrix allows a quick and rapid adjustment and adaptation of the press.

Abstract: A laminated core can be contained in a rotor and/or in a stator and include at least one first sheet metal part assembly and at least one second sheet metal part assembly. The two sheet metal part assemblies are arranged alternately lying one against the other in a stacking direction. Every first sheet metal part has first teeth projecting from a connecting part radially relative to the axis of rotation. Correspondingly, every second sheet metal part has second teeth projecting from a second connecting part. The first teeth extend from the axis of rotation at a distance different from how far the second teeth extends from the axis of rotation to form a step to mesh the rotor with an associated stator and increase the air gap between them without increasing dimensions of the laminated cores in the stacking direction.

Abstract: A method to produce a component from a workpiece via a press which includes at least one die to form the workpiece. The workpiece comprises at least one of a metal, a metal alloy and a coating and has a form of a hollow part. The method includes internal high-pressure forming and/or hydraulic back-pressure forming the workpiece via a fluid and the at least one die at a temperature below a first hardening temperature of the workpiece, and subsequently partially or completely hardening the workpiece by heating the workpiece above the first hardening temperature and then immediately cooling the workpiece. The heating and the cooling are each essentially conducted without a forming so that a fabricated component results.
