Due to the up and down movement of the slide in time with the press ram none during the times of raising and lowering the ram Adjustment movements of the module are made, because otherwise the slide with the tools protruding from their carrier collide.
  • the module according to FR-A is adjustable in the transverse direction; however, it is not possible to use more than one or Several tools of such a module processing operations simultaneously to make.
  • the tools are removed from the press ram or the Sliders during the work cycle are adjusted directly from the rest position to the work position, so that precautions are to be taken with respect to overlaps from the top protruding tools and the sliders.
  • the slide also have a fixed Position in relation to the material to be processed and changes in the material width require a retrofitting in order to also process the edges in the material to be able to make the same way.
  • the tape position is therefore the Transverse position of the module, the position of the band tool, the position of the band slider and the Position slider tool to be considered.

After completing these shifting processes, the modules are fixed in this position and during the entire machining process with a variety of Lifting processes and machining cycles have not changed. Operation of these individual frames cannot be changed during the processing of a material band or a lot will; the same applies to the X-Y position of the individual frames.
  • each individual frame must be changed again in the course of a set-up process be returned to its HOME position and from there to its new position be adjusted. There is no shifting movement between two processing cycles intended; the individual frames moved into the HOME position punch empty. It is it is not possible for single frames to move directly from one processing position to the next Machining position to be moved; the individual frames must go through beforehand Slide valve in a common O position (HOME position).

  • This document shows a rigid follow-up tool, in which the material feed in steps are always the same; Furthermore, as in FIG. 10 clearly visible - to set this constant material feed with the help of a side cutter, cut off lateral material parts or formed steps which the feed is oriented, so that a lateral relative movement between the material and module is inconceivable.
  • the tools are in a fixed position set against the tape position; this position changes during the Not material processing, only different tools can be used for this Machining can be selected.
  • the selection of those necessary for the respective stroke Tools are hit by a template that has defined stop edges.
  • the pneumatic cylinder which pushes the slide with its fixed stop edge to the front presses on the stop edge, activates the required number of strokes by the Template defined combination of stamps. This is determined by the template Selection cannot be changed from hub to hub and therefore not as Activation device can be understood in the sense of the invention.
