It is often necessary to redirect the actuating force acting on the machining tool by means of a corresponding device so that it can act in a machining direction of the machining tool.
  • a rocker mounted in the machining tool around a fixed pivot point is often used, the first arm of which is acted upon by the drive device generating the actuating force and the second arm of which is a tool insert in the machining direction that carries out the bending, embossing, cutting or punching process acted upon. If the first arm of the rocker is deflected by the drive device in a first direction of movement, this leads to a corresponding deflection of the second arm of the rocker in a direction of movement opposite to the first direction of movement, which results in a deflection of the force acting on the machining tool by 180 degrees.
  • rocker has a number of disadvantages, in particular it is difficult with the known rockers to achieve high stroke rates of the tool insert acted upon by the rocker.
  • Another disadvantage that the use of a rocker with such machining tools entails is that with such The rocker can only deflect the force by 180 degrees if complex designs that would lead to expensive rocker design are to be avoided.

  • This movement which takes place in a first actuation direction, is deflected by the force deflection device 20, as will be described below, so that the actuation force acting on the machining tool 1 is also deflected.
  • machining tool 1 The function of the machining tool 1 will now be discussed on the basis of a bending process. It is clear to the person skilled in the art that the function of the machining tool 1 described is not restricted to such shaping machining of the workpiece W. Rather, to name just a few examples, embossing or - as examples for material-separating machining of a workpiece W - cutting or punching is possible.
  • FIGS Figures 6 to 9 show the machining tool 1 at the end of a machining process, one can see in particular from the Figure 8 that between the upper tool part 1b and the lower tool part 1a there is the workpiece W which has a curved edge R as described below.

  • the tool insert 4 is in its lower end position.
  • the workpiece W to be machined is introduced between the upper tool part 1b and the lower tool part 1a, then the holding plate 7 is lowered.
  • the punch 8 ' acts on the workpiece W and presses it against the support 5 so that it is arranged in a fixed position in the machining tool 1. Then the first actuating element 11 and thus the second actuating element 12 acted upon by it are acted upon by the actuating force generated by the drive device external to the tool.
  • This actuating force is transmitted from the force deflection device 20 to the tool insert 4, so that it moves from its into the Figures 6 to 9 shown lower end position against the restoring force of the restoring device 40 in its in the Figures 3 to 5 shown upper end position is deflected and thus acts on the workpiece W, whereby it is bent, that is deformed.

  • the resetting device 40 moves the tool insert 4 downward, so that it fits into the Figures 6 to 9 occupies the lower end position.
  • the force deflection device 20 deflects the restoring force of the restoring device 40 so that the second actuating element 12 and thus the first actuating element 11 acted upon by it are moved back into their upper end position shown in these figures. A new bending operation can then be carried out in the subsequent working stroke.
  • the force deflection device 20 has a guide rail 23 which has a guide channel 24, in which a number of force transmission elements 25 are movably arranged, which - unless otherwise described - Are designed as rolling elements.

  • a second opening 26b which acts as a force output 22 of the force deflection device 20 and into which the second end 4b of the tool insert 4, which is designed as a projection 4b ', is immersed. If the actuating element 12 is now moved in its first actuating direction by the actuating force of the drive device, while its second end 12b is immersed in the guide channel 24 via the first opening 26a, this causes the force transmission elements 25 in the guide channel 24 of the guide rail 23 to be displaced.
  • the force transmission elements 25 are arranged in a row in the guide channel 24, the deflection of the first force transmission element 25a acted upon by the second actuating element 12 is transmitted via the further force transmission elements 25 to the second force transmission element 25b acting on the tool insert 4, so that the tool insert 4 is thereby transmitted in the second Actuating direction moves.
  • the configuration described thus makes it possible in a simple manner to transmit an actuating force acting in a first actuation direction by means of the force deflection device 20 described to a machining force acting in the second actuation direction without a rocker, as in the known machining tools or a similar construction.

  • the use of cylindrical or cylinder-like force transmission elements 25 has the advantage that this results in a line contact between adjacent force transmission elements 25, whereas in the case of spherical force transmission elements 25 there is only point contact. A line contact advantageously allows a higher power transmission.
  • the Figures 1 , 2nd and 5 in addition to the force deflection device 20 also show the resetting device 40, which - as described - serves to force the force deflection device 20 from its in the Figure 5 shown second end position, in which it was moved by the action of the drive device, in its in Figure 2 to move the first end position shown back.
