Abstract (en)
[origin: WO2019110760A1] The invention relates to a device for stamping a blank (50) in order to produce a stamped part. The device includes a punch (40) comprising a bearing surface (41), an anvil (70), a die (80) and means for generating a magnetic field (60), provided in the punch, level with the bearing surface. The device is configured, in an initial position, so that: - the bearing surface of the punch receives a portion of a first face of the blank, - the anvil and the means for generating a magnetic field are placed on either side of the same portion of the blank, the means for generating a magnetic field (60) being opposite the first face (51), and the anvil (70) opposite a second face (52) of the blank, at a distance from the second face, - the die (80) is placed opposite the second face (52), level with another portion of the blank. The means for generating a magnetic field are configured to apply pressure on the blank in the direction of the anvil, in a direction Z'Z. The device includes first means (43) for moving the punch in the direction Z'Z and second means (72) for moving the anvil in the same direction.
