The invention relates to a pair of hand-operated pliers (1), in particular pressing pliers, with jaws (6, 7) and hand levers (4, 5), wherein the jaws (6, 7) are pivotable around a preferably common rotational axis (x). Furthermore, one hand lever (5) is connected by a joint to one of the jaws (7), and a pressure support is located between the hand levers (4, 5) for the formation of a toggle (K). In order to further improve a tool of this type, particularly with respect to the design of the pressure support, it is proposed that the pressure support consist of a support roller (18) arranged on one hand lever (4), and of a curved section (19) which is attached to the other hand lever (5) and which works together with the support roller (18).

The invention relates to a transmission mechanism for a drive system, having at least one tensioning device and acting in two directions. For force transmission, the tractive device runs between a drive roll and an output roll, which are carried by a frame. A spring coupling is connected in the force transmission section between the drive roll and the output roll and has a nonlinear force-distance characteristic curve.

The invention relates to a replaceable die for pliers to press workpieces, such as for crimping pliers for pressing electrical connector elements. By replacing the die, the pliers can be adapted to the press operation to be performed, such as adapting a crimping pliers to different types and sizes of the connector elements to be pressed. The die according to the invention comprises a first and a second die half that can be inserted into the pliers together and removed from the pliers together. The two die halves each have a guide for this purpose. Both die halves each further have a first connecting element for releasably attaching the die to the pliers. Both die halves finally each have a second connecting element for releasably attaching the die to a storage fixture. This ensures that the die formed by the two die halves is held in the storage fixture during or after removal from the pliers, and remains therein for storage.

A double crimping tool for fastening an electrical conductor with insulation to a contact element, which includes a front crimping unit with a front drive cam plate and front crimping stamps for forming a front press section in the region of the stripped end of the conductor; and a rear crimping unit with a rear drive cam plate and rear crimping stamps for forming a rear press section in the region of the insulation of the conductor. The crimping stamps are displaced by rotation of the drive cam plates. By levers the two drive cam plates are connected to a shared force introduction element such that during the pressing procedure at first optionally the front or the rear drive cam plate is rotated by a predefined initial pressing angle while the other drive cam plate is made to rotate only after the first drive cam plate has attained the initial pressing angle.

The present invention relates to a positioning device for positioning an element to be crimped in a crimping tool, for example a wire end sleeve or an electrical connecting plug. The invention further relates to a crimping tool for crimping a connecting element to be situated in a pressing axis. To allow the element that will be crimped to be brought into the pressing axis, the positioning device has a retaining unit for retaining, about its periphery, the element that will be crimped. The retaining unit has a retaining opening which encompasses the pressing axis coaxially. The positioning device further permits the positioning of the element that will be crimped within the pressing axis, in order, in particular, to ensure the necessary insertion depth of the element to be crimped in the crimping tool. For this purpose, the positioning device of the invention has an axial stop, with which the position in the pressing axis of the element to be crimped can be defined. According to the invention, the size of the retaining opening of the retaining unit can be adjusted coaxially in relation to the pressing axis. The size of the retaining opening can therefore be increased and decreased, with a center axis of the retaining opening coinciding with the respective pressing axis. Moreover, the axial stop is displaceable along the pressing axis, allowing different distances from the crimping tool to be realized.

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.

The invention relates to a tool for assembling a securing ring. The tool comprises two adjusting limbs which are connected to each other in a rotary joint and each free end of which has gripping means for engaging into an assembly opening of the securing ring. The tool further comprises a spindle drive provided between the adjusting limbs for changing the distance between the adjusting limbs. According to the invention, the rotary joint is arranged on the adjusting limb ends opposite the free ends, and the spindle drive is arranged between the rotary joint and the free ends of the adjusting limbs.
