The strip steel stamping and grooving tool (15) arranged between a pressure plate (12) and a swage block (14) of a stamping machine (10) has a carrier plate (16) with slots (18) extending from their underside facing the swage block (14) to their upper side facing the pressure plate (12). Blades of strip steel for stamping (20a, 20b) and grooving (20c) are held in the slots (18) in such a way that their hardened cutting edges (22) project form the underside of the carrier plate (16) and their rounded rear ends (24) face an intermediate metal plate (26) arranged on the upper side of the carrier plate. In order to be able to set the strip steel stamping and grooving tool in a short time without adversely affecting the output of the stamping machine, the intermediate plate (26) is of 0.8 to 1.5 mm gauge metal with a yield strength Rp0.2 of 20 to 90 N/mm<2>, a tensile strength Rm of 65 to 150 N/mm<2> and an elongation at break delta of 3 to 35 %. For setting, a 0.5 to 1.5 mm thick elastomer plate (28) with a hardness of 60 to 100 Shore A is applied to the intermediate plate (26) and replaced for normal operation by a metal plate. |
