Abstract

Pliers (1) for crimping workpieces include a first mounting die (5) having an outline, a second mounting die (6) having an outline, a first crimping die (8) and a replaceable second crimping die (9) being mounted to the second mounting die (6). The replaceable second crimping die (9) in its mounted position has a portion (11) extending beyond the outline of the second mounting die (6) and a flange (10) not extending beyond the outline of the second mounting die (6). Bores (25) are arranged in alignment in the second mounting die (6) and in the replaceable second crimping die (9). A removable fixing screw (26) is arranged in the bores (25). At least one circumferentially closed opening (14, 15) is arranged in a region (13) between the portion (11) and the flange (10). A transverse support member (16, 17) is arranged in the circumferentially closed opening (14,15). The transverse support member (16, 17) extends beyond both sides of the flange (10). At least one circumferentially open opening (20, 21) is arranged in the second mounting die (6), the circumferentially open opening (20, 21) supporting the transverse support member (16, 17) to transmit power and to prevent shifting of the transverse support member (16, 17) with respect to the second mounting die (6). A drive (2) moves one of the mounting dies (5, 6) toward and away from the other mounting die (6, 5
