  • the resulting Workpieces differ in their outer Shape and in its dimensions quite significantly from that of Sheet metal fed to the press.
  • presses of this type there is usually a transfer device provided with the help of which in the successive processing stages increasingly deformed Workpieces from press station transported from press station become.
  • the parts go through both Cutting and forming stations, the workpieces especially in the cutting stations in their outer contour can be changed significantly.

  • For transporting the workpieces serves a three-axis transfer device, the two pairs of gripper rails having.
  • the gripper rails of the first Gripper rail pairs are in a relatively large side Spaced from each other and used for transport of relatively wide workpieces, for example during the introduction the same in a cutting station.
  • the slightly lateral Gripper rails arranged at a distance from each other below the die of a press station concerned and serve to accommodate a cut out, down through the die passed through the workpiece.
  • Both those in large lateral distance from each other arranged gripper rails as well as those closely spaced parallel to each other Gripper rails extend over several press stations.
  • the gripper rails guide the workpieces a cyclical longitudinal movement.
  • To record and Releasing the workpieces is a drive device provided by means of which the gripper rails of each Gripper rail pair towards and away from each other are movable.
  • the drive device is designed so that the transverse movement of the Gripper rails in the opening and closing sense synchronously he follows.
  • the gripper rails arranged at a greater distance go through a larger path than that in smaller spaced gripper rails.
  • a gear transmission represents the relation between both movements for sure.
  • a Press with an automatic transfer device Create workpieces from press station to press station, which enables a space-saving design.
  • the invention defined in claim 1 is one for a press with several press stations

  • the first transfer system is arranged by the two in a first press area Gripper rails formed that essentially parallel to each other and parallel to the direction of transport are arranged.
  • This gripper rails can by the corresponding drive means moved both in the longitudinal direction what corresponds to the actual transport movement, as well as in the lateral direction, i.e. towards each other and away from each other, as well as in the vertical direction, with constant distance moved perpendicular to the transport direction become.
  • the latter movement is usually one Lifting and lowering movement, which takes place in the vertical direction. This movement is used to lift workpieces out corresponding matrices or the insertion into them.
  • the lateral movement component serves to open and close, the gripping means carried by the gripper rails engaged with the workpiece when closing and be separated from the workpiece when opening.
  • the Transport movement is thus carried out with approximated Gripper rails while returning with each other removed gripper rails.
  • This section of the transfer system serves first Line the transport of the workpieces through press stations, in which the workpiece in its outer contour originally sheet metal introduced into the press is still largely is similar. It is particularly important that the dimension transverse to the transport direction, i.e. the width of the workpiece and thus the outer edges of the matrices in question are not too far apart in this area.
  • Transport rails arranged by trusses are interconnected.
  • the crossbeams carry gripper means such as suction devices, suction spiders or the like.
  • the transport rails are with drive means provided that this both a lifting and lowering movement can also give a feed movement. During the the normal operation of the press changes the distance of the Not transport rails to each other.
