Abstract: A method and apparatus for monitoring the wear of manual pliers. The principles focus on manual pliers, in which press elements can be pressed onto a workpiece and the degree of pressing that can be achieved by actuating the manual pliers can be adjusted with a presetting device. A reference position of the presetting device is measured prior to a first use of the manual pliers, this measurement involving actuating the manual pliers. By an adjustment of the presetting device, the press elements are brought into a position with a reference degree of pressing. Next, after use, the wear position of the presetting device is measured in the same manner, to bring the press elements into a position with the degree of pressing. A message is output when the degree of the wear position deviates from the degree of the reference position by more than the degree of wear permissible.

Abstract: The invention relates to tools (1), such as crimping tools, comprising an acting part (31), for moving a movable tool (7) relative to a stationary tool (6) for example, wherein furthermore the acting part (31) can be moved in a motorized manner. In order to specify such tools in an advantageous embodiment, a longitudinal axis (L) of an electric motor (9) provided in order to drive the acting part (31) extends below the acting part (31) when the motor is horizontally oriented.

Abstract: A crimping tool has crimping dies arranged in a star shape directed at a crimping region and subjected to rotational action radially outwards for the crimping movement by means of an actuating part. The crimping dies are mounted about an axis of rotation transversely to the longitudinal extent thereof for pivoting-in and form an abutment region on the crimping region side of the axis of rotation. A radial movement and/or circumferential movement is brought about to coincide with the rotational action on the crimping dies, in order to obtain abutment of a crimping die in the abutment region thereof against the counter-abutment region of another crimping die adjacent to the crimping die in the pivoting direction or counter-pivoting direction.

Abstract: The invention relates to a measuring gauge and a method for determining the diameter or cross-sectional area of an object whose cross-sectional shape is adjustable such as, for example, a litz conductor. A first measuring disc comprising a helical slot running around the center of the measurement disc and tapering down is connected in a rotatable fashion by a central axial connection to a second measurement disc comprising a slot running steadily from the vicinity of the center to the edge, the slot tapering in the same direction as the slot of the first measuring disc. A material measure for reading the detected measurement is provided on one of the two measurement discs. When the measurement discs are counter-rotated to one another, the overlapping sections of the slots form an opening into which the object to be measured is inserted, and the size of the opening is altered by counter-rotating the measurement discs to one another.

Abstract: The invention relates to a crimping tool having crimping indenters (7), wherein the crimping indenters (7) are arranged in a star shape directed at a crimping region and are subjected to rotational action radially outwards for the crimping movement by means of an actuating part, wherein the crimping indenters are further mounted about an axis of rotation (8) transversely to the longitudinal extent thereof for pivoting-in and form an abutment region (9) on the crimping region side of the axis of rotation (8).

Abstract: The invention relates to a method according to which a metal (13) is re-shaped by a primary forming process. The aim of the invention is to improve such a method so that heat can be relatively easily added to the part and so that the addition can be varied as regards space and time. To this end, a voltage is applied to parts of the primary forming device between which the metal is disposed during the insertion process and/or during the primary forming process and/or during a subsequent treatment in the primary form after the primary forming process so that a closed circuit is produced and heat energy is supplied to the metal by the closed circuit.
