  • the folding or flanging tool has two driven
  • the folding elements can be delivered in succession to the common folding position in three or more folding steps and thereby bend the workpiece fold or flange stepwise until the desired final angle is reached.
  • the flange or fold is bent in each case in the same direction in the successive folding steps. This folding process can be performed with high precision.
  • the folding steps follow each other quickly, on the other hand, the residence time of the respective folding element in engagement with the Maschinen Swissfalz or -flansch
  • Folding technology is significantly faster, more efficient and less expensive than the state of the art. This also has a positive effect on integration into a clock-bound one
  • the folding elements can be a common drive
  • folding elements are each mounted independently movable.
  • the Swiss-Shavelement performs a multi-axis sliding / pivoting movement and the Fertigfalzelement a pivoting movement.
  • the bearings of the folding elements are designed accordingly.
  • the drive has a rotating drive shaft and a transmission for drive transmission to the folding elements.
  • the step and movement sequence as well as the avoidance or retraction movement of the folding elements can also be controlled via the transmission.
  • Such a drive design has particular advantages in terms of performance and low construction costs. For the folding process a 360 ° rotation of the drive shaft is sufficient. At the end of the folding tool automatically resumes the starting position in which all the folding elements are in a retracted position and allow a collision-free workpiece change. In addition, the control is much easier.

Abstract

L'invention concerne un outil de pliage (2) et un procédé de pliage flexionnel en plusieurs étapes d'une pièce (5). L'outil de pliage (2) comprend trois éléments de pliage (13, 17, 21) ou plus entraînés et superposés, qui sont avancés en un point de pliage commun, au moins un élément de pliage (17, 21) réalisant un mouvement de pivotement. Des angles de pliage d'environ 160° ou plus sont pliés successivement au cours de plusieurs étapes de pliage au moyen de l'outil de pliage (2).
