Definitions

  • the invention relates to a method for controlling the Drive of a large section press with suction beam transfer and an apparatus for performing the method according to the preamble of claims 1 and 4.
  • Large section presses are used to manufacture large Sheet metal parts used for the automotive industry, such as Example of the forming of a motor vehicle roof, a floor assembly or large-walled side parts.
  • sheet metal parts through several processing stations transported, in each of which a further forming step on Workpiece is made.
  • the transport of the workpieces takes place by means of transfer devices, one between spatially two-dimensional suction beam transport or a three-dimensional gripper rail transport.
  • a disadvantage of the known device according to EP 0 754 509 is the fact that there is freedom of movement for the workpiece is only improved by the electronic linear actuator.
  • a any pivotal movement of the workpiece is off mechanical drives via longitudinal rods and press-controlled cam drives known (DE 41 10 215).
  • DE 41 10 215) the electronic linear actuator.
  • this in turn has the disadvantage that the Trajectories can be changed little.
  • From the EP 0 499 901 are also curve-controlled adjusting means directly to the trolley for the suction beams provided certain pivotal movements of the sucker bars perform. This also requires an exchange of the mechanical control curves to change the Swivel motion.
  • EP 0 818 254 A2 shows an arrangement for a Crossbeam or a sucker beam, its pivoting is carried out by means of servomotors. There is one Direct attachment of at least one servo motor with gear provided per suction beam.
  • the invention has for its object a method for Control of the drive and a device for Implementation of the process for a large section press propose at which a maximum of variability of the Movements to adapt to a wide variety of geometries of the workpiece is made possible.
  • the invention is based on the main idea that within a GT press procedures that take place require a wide variety of conversion movements.
  • the forming process can take place much later to very deep and within the same GT press steep-walled sheet metal parts with a lot larger vertical movement and possibly also pivoting movement must be removed from the lower tool before the actual feed movement in the horizontal direction he follows.
  • the ideal case is a combination of all movements, d. H.
  • the combination is decisive for the present invention of the mechanical longitudinal drive or horizontal drive both with the vertical drive via programmable electric drives as well as a programmable rotary actuator for the Vacuum bar to ensure an optimal entry and exit situation on To achieve the workpiece.
  • This will make it variable generated electronic curves because of the variable stroke movement and the swivel movement on the suction bar to an optimal Adaptation of the respective workpiece geometry in the respective Processing stage leads, so that the movement for the Implementation process can be optimized.
  • Inside the GT press can therefore vary from level to level Movements during the transfer movement take place and are free be programmed.
  • the operational security remains due to the mechanical feed drive completely received, in particular to remove the Vacuum bar from the danger area of the processing stages serves.
  • the vertical drives can be connected to each other via a longitudinal shaft get connected. Through this execution, a trouble-free movement guaranteed when a single vertical drive fails.
  • the drive motors for the swivel drive can preferably be arranged in the feed levers themselves. So that no relative movements occur during feed the drive motors can also be rotated with fixed points Cam box must be stored in the drive lever.
  • the first two forming stages are one Large section press 1 with suction beam transfer 2 shown.
  • the feed drive of the transfer 2 is open or closed feed curves 3 and Feed lever4.
  • In the feed levers 4 are electronic controlled geared motors 5 for the pivoting movements rotatably mounted.
  • Die Drives 10 of the vertical movement are via longitudinal shaft 11 connected with each other. As a result, a trouble-free movement can be guaranteed when a single vertical drive fails.
