Definitions

  • the invention relates to a press system, in particular a large section press, such as a body press.
  • Press lines are facilities that last for a long time Remain in use for periods, with the change the parts to be manufactured in the press systems.
  • E.g. at Body presses for the manufacture of body parts are at the latest when a model is changed in the Press machine to provide new tools to change the To be able to manufacture body parts. It is increasing however also required while a model series is in progress to convert the press.
  • E.g. can be required on the same press system To manufacture body parts of different series, that require specific tools.
  • the Tools are usually other facilities the press system, workpiece-specific.
  • for transportation the workpieces from workstation to workstation Transfer devices have receptacles or grippers for the workpieces that, at least in some cases, the workpiece counter are adjusted.
  • the tools are mostly on moving tables (so-called sliding tables) out of and into the press system.
  • the sliding tables are additional provided with tooling receptacles for tool changing from the transfer device to the sliding tables handed over and with them out of the press or in this is driven back in.
  • gripping devices provided a transfer device, if they are not required to store in busbars.
  • the Transfer device has two arranged parallel to each other Guide rails on each other towards and from each other away and vertically movable. Both Movement directions are via appropriate drives operated.
  • the gripping devices are on the guide rails longitudinally displaceable.
  • the guide rail contains Stators of linear motors, while the gripping devices of which contain or form linearly movable anchors.
  • a lifting device arranged the several short mounting rail pieces wearing. These can, if necessary, be in direct alignment Extension to be transferred to the guide rail. In this state, all gripping devices that the contains the relevant guide rail, in a receiving rail be retracted.
  • So-called tools can also be used for tooling Filing templates belong. Are between two forming stages Clipboards provided, these must also mostly specially adapted to the workpieces to be machined become. This is done by the shape of the workpieces customized stencils by a corresponding Carrier of the clipboard station held and accordingly the tool contour are formed. It is from the EP 0155332 known, several templates in a clipboard to be provided on the clipboard in the vertical direction are adjustable. This allows individual stencils in an upper active position and others in a lower one Passive position are transferred, so that a sufficient Template set provided an adjustment to different workpiece contours by raising and lowering can be carried out by individual templates.
  • DE 2124083 A1 discloses a transfer press line with a transfer device, the suction bridges to Transporting the workpieces. Like the sliding tables are the suction bridges from the side Transfer press can be pulled out. In the area between two Press stands are provided in each case, between which an intermediate space is formed through which the suction bridges can be run through.
  • the press system according to the invention has several Press levels on that regarding parts transport are linked together by a transfer device.
  • the transfer device is set up to handle the workpieces if necessary with interim filing Transport clipboards from press level to press level.
  • the transfer device has for receiving the Workpieces workpiece-specific workpiece holding means, which are usually to be changed when changing tools.
  • the transfer device points to the connection of the workpiece holding means Couplings that serve to secure a mechanical connection between the workpiece holding means and the rest of the transfer device.
  • the Couplings are preferably arranged so that the essential to effect the transfer movement Drive devices on the transfer device remain while the workpiece-specific parts are replaced become. If necessary, these can still be a or have several numerically controlled drive units, however, they can also be completely passive.
  • a control device is provided on the press system, which controls a transport and transfer device.
  • the latter is used to automatically hold the workpiece from their operating position in the press line in to transfer the magazine.

  • After the whole Process under control of the control device, can be changed to manual tooling, i.e. the Workpiece holding means are dispensed with. This can be one bring considerable cost advantage.
  • the partially filigree workpiece holding devices can automatically move into protected positions, i.e. get into their magazines.
  • Another benefit is the elimination of the otherwise manual loading and unloading processes for loading the sliding table with workpiece holding means. Beyond that it is possible to set workpiece holding devices computer-controlled on the CAD and the fine adjustment in the press system yourself, so that personnel are saved can.
  • the compact arrangement of the magazine or magazines the press saves the press operator one, as mentioned additional storage facility for the tooling, which makes the space required to operate the press system decreased.

  • suction spiders can be arranged on the traverses, the couplings between the suction spiders and the Trusses are arranged to act. In this case from the transport and transfer facility only that Suction spiders transferred to the magazines while the trusses remain in the transfer facility. Alternatively the trusses can also be replaced with the suction spiders become.
