Patent ID: 8915113

Claim:
A deep-drawing device for flatly shaped workpieces, comprising: a tool, a deep-drawing plate having at least two fixed projections, the tool having corresponding recesses between lamellae, guides for moving the tool and the deep-drawing plate relative to one another along a travel axis by a first drive such that the projections of the deep-drawing plate move into the corresponding recesses of the tool, the recesses being width-adjustable along a fold axis perpendicular to the travel axis by a second drive in a range between a receiving position width for a workpiece and an end position width, and means for operating the first and second drives whereby the second drive is first activated whereby the workpiece is folded into folds in the recesses as the second drive adjusts the widths of the recesses along the fold axis from the receiving position width to the end position width, and whereby the first drive is subsequently activated to move the projections of the deep-drawing plate into the corresponding recesses of the tool and the folds of the workpiece, deep-drawing the workpiece folds into a final shape of the workpiece.
