ABSTRACT:
A tool set including a punch and a die adapted to be mounted respectively on reciprocating press elements. The die includes an anvil and elastically deflectable blades defining, with the anvil, a die cavity of closed contour. The punch contour is smaller than the die contour so that sheet metal pieces to be joined by the tool set are not cut assume a cup-like configuration at the connecting point. The connecting point has an attractive form at both free sides of the sheet metal pieces.
