Pressing works with holding devices

The invention relates generally to the Pre3werk2euge Art, v.'ie them for compressing small products, for example electrical connectors, are used, and in particular on tools, the means for holding these products in a given position.

Known press tools have had various types of devices intended to accommodate the workpiece, which ii in most cases only served to accommodate and not the product

End a: n handle 2 attached so that it moves the claws (3en Vterkzeuges back into the open position when the force acting in the direction of the arrow F v / is removed.

The actuating handle 2 has a ratchet 8 and the body part the associated pawl 6, which is pivotally attached to the body part with a bolt 7 and tensioned by the tension spring 9 int. This arrangement with the ratchet and the pawl has the effect that after the start of a pressing process the claws are fully closed Position must be moved before they can be opened again.

The slotted attached to the body part 1 by means of the pins 14 Guide piece 13 is used to hold and guide the movement of the movable pawl 12.

In the embodiment shown in FIGS. 1 to 6 is a holding claw 18 disposed between the fixed claw 30 and the movable claw 12. The retaining claw is with respect to the movable claw 12 held by a pair of pistons 17, which in a pair of cylindrical holes 16 formed in the body 15 of the movable Claw are provided is held. Compression springs arranged between the piston 17 and the bottoms 20 of the holes 16 resiliently connect the movable claw 12 and the holding claw

As can be seen from FIG. 2, the locking spring 23 has a locking edge 24 and an anchoring part 22. It is on the bottom part

the movable claw 12 with the aid of a pin or a, iii'ete 21 attached. When the holding claw 18 has been pressed far enough towards the movable claw 12 against the resistance of the compression springs 19 so that the compression springs 19 are compressed up to a given value, the locking spring 23 is deflected so that the locking edge 24 engages in the associated shoulder 25 of the inner claw 1F =. The reason for the relative movement of the claws 12 and 16 to stop will be explained later with reference to the operation of the V / Erkseuges. A push button 26, which reaches through a hole 26a in the guide block 13, is used to deflect the Iciegelfeder 23 by hand, so that the locking edge 24 can be released from the shoulder 25 if this is necessary during the work process. The working process of the exemplary embodiment according to the invention shown in FIG. 1 is described in more detail below with reference to FIGS. 3 to 6,

Fig. 3 shows the positions of the fixed claw 30, the movable claw 12 and the holding claw 18 at the beginning of the pressing process. In this position, the claws 12 and 30 are quite far apart, corresponding to the structure of the actuation mechanism of the pressing tool, and the holding claw 18 is held close to the movable claw 12 by the engagement of the mirror edge 24 in the shoulder 25. As a result of these positions of the claws 18 and 12 relative to one another, the compression springs 19 between the piston 17 and the base parts 20 of the punches 16 are under considerable pressure. 7a \ at this time there is sufficient between the claws 18 and 30
