ABSTRACT:
Pliers (1) for crimping workpieces include a pliers head (2) including at least two cover plates (6, 7) and a recess (3), the cover plates (6, 7) having rectilinear channels arranged therein. A stationary crimping (4) die is arranged inside the recess (3) of the pliers head (2). A movable crimping die (5) is arranged inside the recess (3) of the pliers head (2). A guiding element (22) includes two spaced apart guiding projections (27, 28) and it defines a line of movement (33), the guiding element (22) including an opening (39) for its stroke (34), being connected to the movable crimping die (5) and linearly guiding the movable crimping die (5) in the rectilinear channels being arranged in the cover plates (6, 7). A bearing (37) is arranged at the cover plates (6, 7) and in the line of movement (33) between the two guiding projections (27, 28) of the guiding element (22) to enlarge the distance (24) between the two guiding projections (27, 28). The bearing (37) is fixedly arranged in the opening (39) of the guiding element (22). A toggle lever element (35) is supported on the bearing (37). A stationary handle (8, 9) is fixedly connected to the pliers head (2). A movable handle (10) is pivotable with respect to the pliers head (2) and it is connected to the guiding projection (27) adjacent to the crimping dies (4, 5) and to the toggle lever element (35). A toggle lever drive (36) to linearly move the movable crimping die (5) toward and away from the stationary crimping die (4) is provided.
