Abstract: The invention relates to a crimping pliers network (39) which comprises pressing pliers (2), an electronic control unit (31) (in particular a smartphone or a tablet) as well as a data storage device (37) (in particular a cloud storage (38)). According to the invention, a die (3, 4) of the pressing pliers (2) comprises an identifier (18, 19) which can be captured by a capturing device (21) of the pressing pliers. Data (48) from the data storage device (37) and being specific for the captured identifier (18, 19) is provided to the control unit (31). The data might be a desired pressing force curve (49), a desired pressing displacement curve (50) and/or information concerning a workpiece for which the dies (3, 4) are designated. In this way, it is possible to increase the process safety when using the crimping pliers (2). Furthermore, the invention relates to a method for pressing a workpiece.

Abstract: The invention relates to a pressing tool, crimping tool or cutting tool (1; 2; 3) with a tool jaw (5) which is supported at a supporting body (24) by a guidance (28) having a remaining measuring degree of freedom (26). The tool jaw (5) is supported at the supporting body (24) in the direction of the measuring degree of freedom (26) by a mechanical parallel arrangement of an elastic supporting element (14) and a sensor (84). Here, the stiffness of the elastic supporting element (14) is dimensioned such that for the maximum of the effective working force of the pressing tool, crimping tool or cutting tool (1; 2; 3) the sensor (84) has a maximum deflection of at least 0.1 mm or at least 1°.

Abstract: A stripping tool is formed by stripping pliers. In use, the stripping tool is closable with a closing stroke having a cutting stroke part, a stripping stroke part and a free stroke part. In the cutting stroke part, a closing movement moves at least one stripping blade into a closed position so that the stripping blade cuts into the insulating sheeting of a cable to be stripped. During the stripping stroke part, the cut insulating sheeting is partially stripped from the cable. In the free stroke part, the stripping blades are laterally passed alongside the partially stripped part of the insulating sheeting. A transition point from the stripping stroke part to the free stroke part is adjustable so that it is possible to change the length over which the separated part is partially stripped without any change of the length of the closing stroke of the stripping tool.

Abstract: The present invention relates to a set of interchangeable crimp units for a crimping machine. According to the invention each crimp unit comprises an integrated sensor for measuring a crimping force or a crimping displacement during the crimping process.

Abstract: The invention relates to stripping pliers (1). During a cutting stroke of the stripping pliers (1), cutting blades (14a, 14b) radially cut into an insulation of a cable (13). In a subsequent break-away stroke, the partially cut sub-region (33) of the insulation of the cable (13) is broken away. Finally, in a stripping stroke the broken away sub-region (33) is pulled along the longitudinal axis (19) of the cable (13) from the electrical wire (39). In order to avoid that in the stripping stroke, wherein the forces between the cable and the cutting blades (14a, 14b) suddenly drop, the hand levers (2, 3) perform an uncontrolled fast closing movement according to the invention at the transition from the break-away stroke to the stripping stroke a spring element and/or damping element (37) becomes effective which preferably comes into contact with a roller (36) of a lever (22).

Abstract: The invention relates to a stripping tool, in particular stripping pliers. The stripping tool is here used for a multi-wired cable. According to the invention two pairs of stripping blades are used in the stripping tool. The two pairs of stripping blades are moved in preferably parallel planes (60, 61) besides one another. According to the invention it is possible to simultaneously strip the insulations of e.g. four conductors of a four-wired cable.

Abstract: The invention relates to manual pliers (1) which comprise a fixed cutting jaw (26) and a movable cutting jaw (23). The manual pliers (1) comprise a first maximal opening position in which it is possible to run through a working stroke part caused by the closure of the hand levers (2). In the first maximal opening position the latching lever (16) and a pushing lever (19) engage with a toothing (32) of the movable cutting jaw (23). With the actuation of the latching lever (16) it is possible to transfer the manual pliers into a second maximal opening position in which the opening angle of the hand levers (2) is larger than in the first maximal opening position. In the second maximal opening position the latching lever (16) and the pushing lever (19) do not engage with the toothing (32) of the movable cutting jaw (23). For the definition of the two opening positions, two stops are used which are formed by the latching lever (16) and a swivel bolt of the latching lever (16).

Abstract: The invention relates to a stripping tool (1) comprising at least one stripping jaw. A cutting element (10, 11) is exchangeably assembled with the stripping jaw under use of a mounting groove (56, 57). Preferably, mounting and dismounting is performed along mounting axes (58, 59) having an orientation perpendicular to a pivot plane of the pliers jaws (3, 4). The inventive stripping tool (1) comprises an exchange position in which the mounting and dismounting of the cutting elements (10, 11) is possible, in particular through a cutaway (62, 63) of a side wall (64, 65) of the pliers jaws (3, 4). If the exchange position is left a movement of the cutting element (10, 11) is blocked by a securing element (66) formed by the side wall (64, 65) so that a securing of the position of the cutting element (10, 11) is provided.

Abstract: The invention relates to a cable stripping tool (1). A cable stripping unit (5) is built with two cable stripping jaws (6, 7). The cable stripping jaws (6, 7) are pivoted towards each other in a pivot plane (9) during a cutting stroke. During a subsequent cable stripping stroke the cutting jaws (6, 7) are moved along a cable stripping axis (15). A mounting axis (58, 59) has an orientation vertical to the pivot plane (9). A cutting element (10, 11) is detachably mounted along the mounting axis (58, 59) with the cable stripping jaw (6, 7). Outside from an exchange position the cutting element (10, 11) is blocked against the removal along the mounting axis (58, 59). The exchange position is induced by the drive (16) of the cable stripping tool (1). In the exchange position the cutting element (10, 11) is freed with respect to a movement along the mounting axis (58, 59) so that demounting of the cutting element (10, 11) and mounting of a new cutting element (10, 11) is possible.

Abstract: The invention relates to hand pliers (1) which are in particular embodied as crimping pliers. According to the invention, the hand pliers (1) comprise a counting device (16) which counts the number passed working strokes (17). The counting device (16) is built with a sensor which senses the distance or displacement of two components moved relatively to each other over the working stroke (17), in particular the distance or displacement of hand levers (2, 3). If the count number registered by the counting device (16) exceeds a threshold value, it is possible to produce a display at a displaying device of the hand pliers (1) which indicates that an exchange of drive elements or an exchange of dies or a certification of the hand pliers is required.

Abstract: The invention relates to crimping pliers (1). The crimping pliers comprise a spring element (7) which is located in the force flow between hand levers (3, 5) and dies (12). The spring element (7) builds a force-displacement-compensation element (8) which provides the option to be able to crimp workpieces with different cross-sectional areas with the crimping pliers (1). According to the invention, the spring element (7) which builds the force-displacement-compensation element (8) is built in the region of the pliers head (4) of the crimping pliers (1). Preferably, the spring element (7) is a spring in the shape of an arc of a circle or a spiral spring (44) which extends in circumferential direction around the die axis (13).

Abstract: The inventions relates to crimping pliers with two hand levers (3, 5) and two actuation elements (9, 10) located in the region of a pliers head (4). The actuation elements (9, 10) actuates dies (12) between which a workpiece can be crimped. A toggle lever drive (33) with two toggle levers (34, 35) which build a toggle lever angle (36) acts between the hand levers (3, 5) and the actuation elements (9, 10). One toggle lever (34) is built by a roller (23) which is pivotably mounted to the hand lever (5). The roller (23) rolls along a curved track (24) fixed at the other hand lever (3). A forced locking unit (48) is built with a toothed latching lever (28) which is supported for being rotated relatively to the roller (23). A lever part (30) of the toothed latching lever (28) is coupled by a sliding guide to the hand lever (3), whereas the other lever part (29) of the toothed latching lever (28) forms a toothing (31) for latching of the forced locking unit (48).

Abstract: The present invention relates to crimping pliers in particular used for forming at least three recesses at a contact element housing an electrical conductor. The inventive crimping pliers (1) comprise a toggle lever drive (6). The toggle lever drive (6) is built with an elastic pressure lever (18). The pressure lever (18) is preferably built with an offset or cranking (33) so that with the application of a longitudinal force the pressure lever (18) is biased by a bending. The flexible design of the pressure lever (18) provides a variable crimping stroke (in particular also in connection with a forced locking mechanism (28)) for different dimensions of the contact elements to be crimped.

Abstract: The present invention relates to a B-shaped crimping die for a crimping tool. The crimping tool and the crimping die are used for crimping a plug with an electrical cable located therein into a B-shape. The crimping die comprises a first crimping die half and a second crimping die half. A B-shaped crimping contour is defined by the crimping die halves in a closed state. A first crimping contour part of the first crimping die half and a second crimping contour part of the second crimping die half together build the crimping contour. Two transition points are located at the transitions between the two crimping contour parts. According to the invention an opening angle of a contour of the second crimping die half increases at said transition points in moving direction of the first crimping die half during the crimping process.
