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.

If an unacceptable deviation from the specification is detected, the sensor device 30, 40 in question controls the respective associated removal device 32, 41 to discharge the coin blank from a main conveyor device 13 which transports the coin blanks from a feeding end 14 to an exit end 15.

Abstract: A blank holder device for a drawing device, for example a drawing press. The blank holder device has a blank holder sleeve, which, in a predetermined position exerts a blank holder force on a blank part. The sleeve is fastened to a head part and is stationary relative to it. To move the blank holder sleeve in a stroke direction, the head part is borne, through a head part guiding arrangement, at least at two front guide locations, to undergo translational motion in a stroke direction, and it is braced to be essentially stationary in all directions at right angles to the stroke direction. On the side opposite the blank holder sleeve, the head part is connected with at least one drive element of the blank holder drive device and that can, together with the head part, be moved by a motor and a coupling arrangement in the stroke direction.

Abstract: A device and a method for forming hollow cylindrical bodies. The device has a plurality of stations. A tool is allocated to each station. The tools are arranged on a common carrier. The tool can be moved between two reversing positions via a main drive. This reciprocating movement is executed intermittently. One of the two reversing positions forms a rest position in which the tool carrier stops in a rest phase. While the tool carrier stops in a rest position in the rest phase, a transport device transports the bodies from one station to the respective next station.

Abstract: A battery cell housing which delimits an interior chamber for receiving a core material providing electrical energy. The battery cell housing consists of a housing shell and a housing cover. The housing shell has a floor and a housing shell wall extending coaxially to a housing axis, proceeding from the floor. The housing cover has a pot or bowl-shaped form. The housing cover is inserted into the housing shell wall at a distance from the floor after the core material has been introduced. The housing shell wall is mechanically connected to the housing cover by a folded joint, preferably a double folded joint. There is no integrally joined connection according to the invention. The folded joint is implemented radially inward toward the housing axis and is located closer to the housing axis than the outer surface of the housing shell wall, when viewed radially to the housing axis.
