Definitions

  • This conventional device does not allow stamping of thin or extra-thin sheets, because the rigidity of the matrix as well as the tightening of the sheet by the blank holder generate non-homogeneous deformations resulting in some areas by lengthening likely cause excessive thinning and in other areas by shrinking tends to cause thickening of the sheet blank, which lead to the formation of folds.
  • the sheet is not sufficiently maintained in the area under the blank holder, that is to say between the blank holder and the cushion of elastic material which does not does not in itself have sufficient rigidity.
  • the lower part 11 of the matrix 10 constitutes an upper peripheral blank holder.
  • the step of releasing the finished part is carried out by the simultaneous ascent of the slide 12 and of the matrix 10.
  • This lower blank holder 7 also comprises air inlet ducts 18 between the sheet blank 20 and the cushion 2 and is secured to the walls 30 by suitable means, not shown.
