  • Patent number: 11967795
    Abstract: The invention relates to a crimping pliers die (1) comprising two die half units (2, 3). The die half units (2, 3) are guided by a guide (51) relatively to each other over the crimping stroke. Crimping surfaces (40, 41) of the die halves (5) are formed by front surfaces of engaging ribs (37). Preferably, the guide (51) comprises a guiding rod (43) formed by an end-sided thickening (42) of a rib (37) and the guide (51) comprises a guiding recess (50) formed by a guiding recess section (45) which connects two ribs (37) to each other. The crimping pliers die (1) can be used for crimping pliers which can e. g. be used for crimping wire end sleeves.

  • Patent number: 11424587
    Abstract: The invention relates to pressing or crimping pliers (1). According to the invention a spring device (35) (which is e.g. embodied as U-shaped leaf spring (36)) is used in the crimping pliers. In an equilibrium position (48) the leaf spring (36) is trapped between stops (49, 50). If the pressing or crimping pliers (1) are moved from the equilibrium position (48) in closing direction the leaf spring (36) is biased by a follower (54) such that the leaf spring (36) generates an opening force. In reversed direction the opening movement of the pressing or crimping pliers (1) from the equilibrium position (48) leads to a bias of the leaf spring (36) by a follower (55) such that the leaf spring is able to generate a closing force. According to the invention it is possible to provide that the pressing or crimping pliers (1) automatically and elastically open when reaching the closed position.

  • Patent number: 11381049
    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.

  • Patent number: 11346732
    Abstract: The invention relates to crimping pliers (1) having a pliers jaw (4) on which a die half (22) is supported. A crimping force biasing the die half (22) is sensed in the crimping pliers by a force sensor. The force sensor is a piezo foil (36) mounted to the pliers jaw. The force sensor senses the whole crimping force or only a crimping force component from which it is then possible to calculate the whole crimping force.

  • Patent number: 10910801
    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.

  • Patent number: 10790647
    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).

  • Patent number: 10355461
    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.

  • Patent number: 9987760
    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).

  • Patent number: 9923346
    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.

  • Patent number: 9912131
    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.
