The invention concerns an arrangement () and a method for the manufacture of can bodies from pot-shaped blanks (). To this end, the blank () is inserted into a bottom tool part (). The blank () is clamped between a downholder () and a counter support surface () of the lower tool part (). For controlling a position value &#x3b1; determining the position and/or position change of the downholder (), a drive arrangement () is provided. The drive arrangement controls the position value in accordance with a predetermined course, so as to move the downholder () into the clamping position or out of the clamping position EP. As soon as the downholder () reaches its clamping position EP, the drive unit () controls a force value in accordance with a predetermined course which determines the clamping force F(t) which is applied by the downholder () to the blank (). This occurs preferably by an adjustment of the motor current I to a predetermined course of the desired value I(t).

Downholder control in the manufacture of can bodies

For the manufacture of can bodies as they are needed for the manufacture of aerosol cans or beverage cans, a special toolis provided which combines the manufacture of the cup as well as the transformation of the cup into a can body into a single tool. The process is based on preferably round metal sheets which are first drawn in a first draw-stretching step of the toolinto cups and then are draw-stretched in a second draw-stretch process, the further draw- and slide-down-stretch to form can bodies. The drawing arrangements are the same in both operating steps. The tools required therefore are simple sturdy tools providing for a simple sturdy manufacturing process.

Tool and method for the manufacture of cans

Referring to a punch device in accordance with the invention, the punch stamp () is driven by a hydraulic actuating drive (), in which case, in connection with an advance device () driven by a servo motor and travel-measuring systems on the ram axis and on the partial-apparatus axis (advance axis), the ram movement is freely programmable relative to the advance movement of the partial apparatus.

Punch device

A device for producing cut-out and/or shaped workpieces, especially for producing rotors and stators of a generator or electric motor, with at least one cutting device and/or at least one shaping device, at least one gripping device for picking up and setting down raw material and/or finished workpieces and at least one transfer device, at which at least one gripping device can travel and be driven.

Arrangement for production of cut out and/or unformed workpieces

A process system and produces metal sheets, including electric sheets, and uses at least one sheet machining unit, particularly a notching device. One or more linear transfer devices or more one sheet stacking devices, one or more sheet feeding unit and one or more sheet removal devices are being configured for stacking at least one sheet metal blank, centering and/or orienting at least one sheet metal blank, (c) at least one of notching at least one sheet metal blanks, separate and/or remove one or more interior sheet metal parts, and deposit the one or more notched sheet metal blanks and/or depositing the one or more interior sheet metal parts.

Process and system for producing metal sheets

A groove stamping machine stamps the required grooves successively into a disk-shaped blank particularly for manufacturing stator and rotor plates for electric machines. The groove stamping machine has a stationary bench which, on the end side, carries a spacing apparatus for receiving the blank. A stamping device disposed on the bench is adjustable with respect to the spacing apparatus. The distance between the spacing apparatus and the stamping device can be adjusted by a ball thread spindle which acts between the spacing apparatus and the stamping device. The fixing of an adjusted distance takes place by the blocking of the ball thread spindle, preferably by way of a disk brake. The stamping device is disposed via a combined roller slide bearing on the bench which permits a low-friction displacement of the stamping device which also supporting the latter in a stiff manner. The combination of the low-friction bearing device and the ball thread spindle, which is preferably arranged close to the blank, permits a precise adjustment and constant maintenance of the desired machining radius. The precision and the compensation of temperature fluctuations also results from the ball thread spindle being preferably arranged in an exposed manner, that is, in a thermal contact with the environment.
