Abstract
A fine blanking press comprises a blanking ram and a counter unit positioned opposite the blanking ram. A press drive is configured to drive at least the blanking ram along a driving direction during a fine blanking process step. A feeding device is configured to feed a process material to a process zone defined between the blanking ram and the counter unit and at least one handling device is configured to handle the process material outside of the process zone. At least one levelling drive is configured to drive the at least one handling device in a same direction as the blanking ram during a fine blanking process step.
Claims8
A fine blanking press comprising:
- a blanking ram;
- a counter unit positioned opposite the blanking ram;
- a press drive configured to drive at least the blanking ram along a driving direction during a fine blanking process step;
- a feeding device configured to feed a process material to a process zone defined between the blanking ram and the counter unit;
- at least one handling device configured to handle the process material outside of the process zone;
- at least one levelling drive configured to drive the at least one handling device in a same direction as the blanking ram during a fine blanking process step such that the at least one handling device follows a driving movement of the blanking ram during the fine blanking process step so as to prevent bending of the process material between the process zone and the at least one handling device during the fine blanking process step;
- a synchronizer configured for synchronizing the driving movement of the blanking ram with a driving movement of the at least one handling device, wherein synchronizer comprises a controller configured to provide a closed loop controlled synchronizing of the press drive with the at least one levelling drive;
- and
- a connector configured to connect the press drive with the at least one levelling drive, wherein the at least one levelling drive is partly or completely driven by the press drive,
- wherein the press drive is one of a hydraulic drive and a servo-hydraulic drive, wherein the at least one levelling drive is one of a hydraulic drive and a servo-hydraulic drive, and wherein the connector is configured to connect at least one hydraulic drive cylinder of the press drive with at least one hydraulic drive cylinder of the at least one levelling drive.
