Definitions

  • the invention relates to a storage and retrofitting station between the tool stages of a transfer press line, which serves to temporarily store the sheet metal parts in order to bridge the distance between the empty stages, to change the position of the sheet metal parts between the tool stages and to convert the part-specific storage templates and the interchangeable parts of the transfer device.
  • each station is equipped with further actuators for changing the position of the sheet metal parts in several degrees of freedom.
  • the invention is based on the problem of designing a storage and retrofitting station according to the preamble of claim 1 more cost-effectively by providing the function-determining parts for changing the position of the sheet metal parts in several degrees of freedom, including hardware and software expenditure for drive control of the actuators, only once for each idle level and remain in the empty position when changing tools.
  • the transfer press line consists of several individual presses set up one after the other in the parts transport direction, which are connected to each other in the press table area by means of clamping bolts and are operatively connected to a common drive by means of a continuous drive shaft.
  • An empty stage is provided between each tool stage, in which a storage and conversion station is located.
  • Each press is assigned separate press stands 11, the width and position of which on the press tables 12 is selected so that there is a space 24 between the press stands 11 of adjacent presses.
  • the transfer press line is equipped with a 2-dimensional or 3-dimensional transfer device, on the carrier rails 1 of which are interchangeable along the direction of parts transport, interchangeable part-specific receiving elements are fastened.
  • Suction cross members 2 are preferably provided as receiving elements, which temporarily store the sheet metal parts in the empty stages during transport between the tool stages on the storage templates 3 used for fixing the position.
  • the storage templates 3 are made in several parts.
  • a plurality of template elements are preferably attached to a common template carrier 4. If the outer template elements protrude into the press stand in the operating state, as shown in FIG. 1, a horizontal shift towards the center of the free space is required during the changeover process.
  • the template carrier 4 are each arranged on the outer ends of the pivotably mounted double lever 6.
  • a sliding block 7 is slidably mounted in a sliding block guide.
  • the pins 8 projecting through both sliding blocks 7 are operatively connected to the spindle nut 9 of a spindle drive consisting of spindle 19 and actuator 23.
  • the double lever 6 and the spindle drive are arranged on a pivoting crossbar 5 which is articulated in the pivot point 20.
  • One swivel cross member 5 is located transversely to the printing direction in the outer area of the storage and retrofitting station and is used for swiveling the sheet metal parts about the y-axis as needed for orientation in order to transport them to the next stage.
  • the position of the axis of rotation is selected so that it approximately corresponds to the axis of symmetry of the sheet metal parts in order to reduce the effort required for corrective movements due to pivoting.
  • the lifting module 17 in the z direction and the driving modules 13 and 22 in the y and x direction allow further degrees of freedom for the orientation of the sheet metal parts.
  • a change carriage 14 which can be extended transversely to the parts transport direction and serves to enclose the storage station in a U-shape when retracted, is used.
  • the change carriage 14 contains in the upper region a frame 10 which surrounds the storage station and which can be displaced vertically by means of lifting devices 18.
  • the pivoted-off template carriers 4 are taken over by a first centering and locking device 16 of the change-over carriage 14 and at the same time released from the double levers 6.
  • a second centering and locking device 21 is actuated by vertical displacement of the frame 10 to accommodate the suction traverses 2 which are in the changeover position above the storage station.
  • one of the suction cross members 2 assigned to the adjacent tool stages is uncoupled in time from the mounting rails 1 and transferred to the change carriage 14.
  • the changing carriage 14 equipped in this way with the suction traverses 2 and the storage templates 3 is then extended analogously to the sliding tables from the empty step area.
  • a second change carriage 14, already provided with new storage templates 3 and suction traverses 2 can simultaneously be driven into the empty step area from the opposite side and the conversion process can be ended in reverse order.
