Definitions

  • the present invention relates to a press or punch with a press frame having at least two spaced apart press frame sections between which a press ram is movably arranged to perform a pressing operation, the press ram having at least two press sections, and a device for transferring workpieces between the pressing areas and the device has a holding device preferably designed as a gripping device for the workpieces and at least one drive means for moving the holding device, wherein the drive means comprises at least one magnetic linear drive.
  • Such a press is for example from the DE 195 06 079 A1 known.
  • This document describes a device for transferring workpieces through a sequence of processing stations of a press, wherein the device has a holding device for gripping the workpieces.
  • the holding device can be moved by means of a magnetic linear motor principle.
  • the press described in this publication has a press frame with two spaced-apart columns, between which a press ram, which has a plurality of pressing regions, is arranged to be movable in order to carry out a pressing operation.
  • the object of the invention is to improve a press or punch of the type mentioned, in particular to allow better utilization of the space between the columns of the press, so that larger pressing areas are available with unchanged dimensions of the press or the press can be made more compact ,
  • the object is achieved by a press or punch with a press frame of the type mentioned, in which at least one of the drive means is arranged at least partially on the side facing away from the press ram side of the press frame sections.
  • This solution has the advantage that a larger space for the pressing areas is available and the press can be made more compact.
  • a plurality of drive means may be provided. In this way, the mobility of the holding device can be increased in the tool installation space.
  • the magnetic linear drives of the drive devices each have a primary part with a motor slide and a guide device for the primary part, the operating devices can be made even more compact.

  • the holding device can be formed by the guide rails extending in a direction transverse to the stroke direction of the press ram and between the two press frame sections. In this way, an even more compact design of the press is possible.
  • the gripping device is formed by the guide devices designed as gripping rails of the linear drives extending in a direction transverse to the lifting axis between the two press frame sections. This makes the press even more compact.
  • the holding device is arranged in a raised position of the press ram between the press ram and a table top, as this makes an even more compact design is possible.
  • the holding device has a plurality of gripping portions which are movable toward each other. This allows the workpieces to be held in multiple positions.
