  • Method for stamping a part from a multi-layered strip
    Patent number: 6401510
    Abstract: A method of stamping a part from an elongated strip of multi-layered material. The multi-layered material includes a viscoelastic intermediate layer, and upper and lower layers that are relatively rigid with respect to the intermediate layer. The method includes providing symmetrically aligned top and bottom punches each including a material displacement edge corresponding with a desired shape of the part. Each of the material displacement edges are defined by a rake surface and a part interface surface that combine to form a positive rake angle. The strip is positioned between the top and bottom punches. The top and bottom punches then shear a portion of the upper and lower layers, respectively. More particularly, symmetrical groove patterns are formed in the upper and lower layers, defining a perimeter of the part. The part is then removed from the strip along the perimeter.
