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: In a method for setting bending of at least one straightening roller in a roller straightening machine, the straightening roller is supported by a plurality of supporting roller devices arranged beside one another in the axial direction, wherein each supporting roller device can be adjusted by an actuating device such that stresses are produced in the straightening roller. To control the actuating device, a control system is provided, by which the adjustment of the supporting roller device can be set manually. Limiting values (vMA, vMI) with respect to the stresses produced in the straightening roller are stored in the control system. In the event of adjustment of one of the supporting roller devices, maxima (MA) and minima (MI) of the stresses produced in the straightening roller are calculated and it is checked whether the maxima (MA) and minima (MI) lie within the limiting values (vMA, vMI).

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.

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 forming tool and a forming method for producing an overpressure predetermined breaking point in a battery cover by deformation. The forming tool has a stamping tool and a die tool and an optional hold-down arrangement. On the die tool a support surface is provided for the battery cover to be deformed to form a forming cavity in the die tool in a depressed manner. On the stamping tool a stamp part and a ring-shaped stamp part is provided corresponding to a bead to be created in the battery cover in the cross-section. During deformation of the battery cover the stamping tool is pressed in the battery cover, whereby material of the battery cover flows into the forming cavity. Thereby the stamping tool is approached to the forming cavity in a manner such that the remaining distance corresponds to a minimum wall thickness at the overpressure predetermined breaking point.

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: An outer ring (29) is first transported to an insertion point (E) in the feed device (34). At the same time, a circular blank ring (30) is brought into a starting position (P) in the feed device. The circular blank ring (29) is first aligned coaxially with respect to an axis (A) using a centering body (61). The circular blank ring moves solely radially with respect to the axis (A). The circular blank ring (30) is then inserted into the hole of the outer ring (29). During this movement, the circular blank ring is aligned coaxially with respect to the axis (A) preferably using a centering channel (54). The circular blank ring (30) carries out a superimposed movement in the axial direction (V) and in the radial direction radially with respect to the axis (A).

Abstract: A forming device and a method for forming an inner rim of an annular round blank. The forming device has a lower tool with a movable die and an upper tool arranged opposite the lower tool along a working axis A. By means of the die, the annular round blank is moved out of a transport plane T and into a forming position U towards the upper tool and into the interior of a holding sleeve. Subsequently, the inner rim is formed with the aid of a forming tool. After forming, the annular round blank is moved out of the forming position U and back into the transport plane T by means of the lower tool and/or the upper tool. The forming device and the forming method can occur while the round blanks are being fed to an embossing station while being transported by a revolving table.
