Problems solved by technology

The disadvantage of this solution is that the replacement process has to be carried out cumbersomely by loosening and inserting the individual extruded profile inserts individually
Another disadvantage is that only a small amount of extruded profile inserts can be prepared on the handle part of the pliers and the weight of the pliers is increased due to the additionally stored extruded profile inserts on the handle
If several extruded profile inserts are stored, there is also the risk that inserts that do not fit together are selected by the user and inserted into the pliers, which can lead to poor extrusion results or even destroy the profile inserts

Embodiment Construction

[0038] figure 1 A clamping tool 01 according to the invention is shown, which is inserted into a clamp 02 . The clamping mold 01 comprises a first mold half 03 and a second mold half 04 , which are connected to each other only indirectly via clamps 02 . The clamps are shown in the closed state, wherein the two mold halves 03 , 04 are arranged against each other. When the clamp 02 is open, then the two mold halves 03, 04 are at a distance from each other ( figure 2 show). When the jaws 02 are closed, the mold halves 03 , 04 are moved towards each other in the closing direction 06 . The sides of the mold halves 03 , 04 pointing toward each other have a plurality of cavities 07 for clamping electrical connection elements of different sizes. To clamp the electrical connection element, the electrical connection element is inserted with the clamp 02 open into the cavity 07 provided for this purpose in the first or second tool half 03 , 04 . Subsequently, the jaws 02 are closed...

Abstract

The invention relates to a replaceable die (01) for pliers to press workpieces, such as for crimping pliers (02) 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 (03, 04) that can be inserted into the pliers together and removed from the pliers together. The two die halves each have a guide (16) for this purpose. Both die halves each further have a first connecting element (08) for releaseably attaching the die to the pliers. Both die halves finally each have a second connecting element (17) for releaseably attaching the die to a storage fixture (18). 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.

Description

technical field [0001] The invention mainly relates to replaceable dies for pliers for crushing workpieces, such as for crushing electrical connection elements. By changing the mold, it is possible to adapt the pliers to the extrusion deformation to be carried out, in particular to the different types and sizes of connecting elements to be extrusion deformation. Therefore, it is not necessary to prepare different pliers for different clamping processes, but only several tools for a single plier. Furthermore, the invention relates to a pliers which can be equipped with such a mold and to a storage device in which such a mold can be stored and by means of which the pliers can be easily switched without additional aids on the mold. Background technique [0002] DE 29810875 U1 discloses a pliers-type tool with exchangeable jaws, wherein the jaws each have a bolt, which can be inserted into corresponding depressions on the lever arm. The disadvantage of this solution is that o...
