Abstract (en)
[origin: EP1632297A1] The stamping or forging process involves producing at least two kinds of holes in blanks in two steps: forging the part (1) from the blank; and perforating the part by means of the perforating tool (10). This is also done in two steps, in each of which part of the total perforations are made, so that the perforated part is completed after the second step. In the first step, the perforating tool holds the party in position for the subsequent perforation step.
