In these cases pneumatic drives are a good alternative. In the application shown above workpieces are punched out of strip material and it is then necessary to cut the remaining lattice-like waste material into pieces. The pneumatic drive selected should be capable of completing the cutting operation with adequate reserve power. Furthermore the cutting blade should be inclined to one side of the production line to produce an oblique cut over a greater distance. This reduces the cutting force required although not the cutting work . If the press in question is not equipped with roller feed this can also be carried out by pneumatic means using a combination of diaphragm pressure units and a linear unit. The diaphragm pressure units are of very flat design and are advanced alternately in an advance return rhythm. Pneumatic components are a highly suitable means of retrofitting devices of this kind to existing systems. Suitable components Twin cylinder ADVU. Linear unit DPZJ. Proximity switch SM. Pneumatic single pilot valves. Roller lever valve RIO. Clamping module EV.

The handling device picks up the oriented castings from the conveyor using a twin-jaw gripper and .
