Abstract (en)

[origin: DE19608551A1] The invention concerns a method for producing stamped parts, in particular plates, which comprises only two steps. In a first method step, the workpiece is blanked inside a device (1) in a fine blanking stage (2) and, after blanking, is moved to a stamping stage (3) by means of transfer tongs (4) which are likewise housed in the device (1). The stamping stage (3) is also located inside the device (1). In a second method step, the inner and outer contours are stamped on the workpiece (5) in the stamping stage (3) such that the burrs produced on the workpiece (5) during the first step are rounded.
