ABSTRACT:
Strip steel stamping knives (1) and, if desired, the strip steel folding rules (2) of a strip steel stamping tool are provided in slots (3, 4) in a carrier plate (5). The strip steel stamping knives and, if desired, the strip steel folding rules protrude downwardly from the carrier plate to cooperate with a counter stamping plate (7). The backs of the stamping knives (1) and, if desired, of the folding rules (2), face a hardened pressure plate (9). In order to achieve an automatic height or elevational adjustment of the stamping knives (1), and if desired, of the folding rules (2), the backs of the stamping knives and, if desired, of the folding rules, are also constructed as hardened cutting edges (11, 12). An intermediate plate (10) is placed between the carrier plate (5) and the pressure plate (9). The hardness of the intermediate plate is less than that of the cutting edges (11, 12) of the stamping knives (1) and, if desired, of the folding rules (2), so that these cutting edges may penetrate into the intermediate plate during an elevational equalization.
