Die for a punching device, punching tool for a punching device with such a die and method for cutting out workpiece parts from workpieces with a corresponding die

摘要

The invention relates to a die for a punching device (1). The die comprises a die base body (15) and a workpiece support body (16) provided on the die base body (15) for supporting a workpiece (8) to be machined, and a cutting device for creating a recess in the workpiece (8) Cutting a workpiece part (38) which is in firm connection with the remaining workpiece (8) via a connection end piece during cutting and is bent into a through opening (27) formed in the workpiece support body (16). The cutting device has a cut-away element (22) and a counter-cut-off element (30) for ablative interaction with the cut-off element (22) by a plurality of cut-off strokes. The Ablängelement (22) and the counter-Ablängelement (30) are relatively displaceable between a Ablängstellung in which the Ablängelementement (22) and the counter-Ablängelement (30) ablängend interact with each other, and an open position in which the Ablängelement (22 ) and the counter-Ablängelement (30) are spaced from each other. Further, the die has guide means for guiding the workpiece part (38).
