Definitions

  • the invention relates to a press system with the Features of the preamble of claim 1, and a Method with the features of the preamble of the claim 12 and a use of a press system associated clipboard, with the features of Preamble of claim 15.
  • Presses or press systems generally have workpiece-dependent ones Components that need, for example Production changeover are to be changed. These components are first tools, the lower tool on one Sliding table and its upper tool on a press ram is held.
  • the sliding table is mostly in the side Can be pulled out in the direction of the press or press system.
  • Parts belong to the workpiece-dependent components of the transfer system, which is the further transport of the workpieces from press level to press level.
  • the transfer system often has holding means (vacuum cups), their position and number of workpieces is determined.
  • the vacuum cups are mostly held on suction frames, which in turn are held on cross beams of a two-axis transfer.
  • the Suction cup frames are workpiece-specific.
  • More workpiece-specific Elements can be found on clipboards, the are arranged between two press stages and the workpieces record temporarily without editing them is carried out.
  • the clipboards have for inclusion of the work pieces referred to as templates, their shape, size and position from the one to be filed Workpiece is dependent.
  • the holding means and the Templates form the so-called tooling.
  • EP-A-0 191 397 includes a transfer press Clipboards known, their templates before the tool change to appropriate holders of the sliding table or of the tool stored on this.
  • the clipboard has a separate transfer a rack and a spring mechanism formed transfer device with the template in a straight line is led to the sliding table.
  • Means for changing workpiece-specific elements the transfer device are not visible.
  • DE 41 24 083 A1 is a transfer press line known, in between individual press stations, clipboards are arranged when changing tools be moved sideways out of the press line.
  • the Clipboards hold those used to hold the workpieces Storage templates can be swiveled around a transverse axis.
  • holders for holding on the clipboards provided by suction devices belonging to the transfer device. The clipboards are used when changing tools together with the storage templates and the suction cups on the side drove out of the press. To do this in the area of A corresponding free space can be provided for the press stand.
  • DE 33 34 021 C1 is a large part step press with a clipboard known Has gripping and holding device for the storage templates. These can be connected to the tool for changing tools.
  • the gripping and Holding device For transporting the storage templates from the clipboard device to the tools the gripping and Holding device that can be moved in the transport direction mounted and appropriately driven racks has, at the outer end of the template held are.
