Definitions

  • the invention relates to a clipboard between processing stages of a forming machine according to claim 1.
  • Clipboards must be set up in the empty stages of presses to bridge the gap between the processing stages.
  • a transfer press with empty stages in the stand areas shows, for example, US Pat. No. 3,875,808.
  • US Pat. No. 4,730,825 also shows an intermediate shelf whose height, which can also be formed by stencils, is adjustable. Likewise, the size of the contact surface or the spacing of the templates from one another can be adjusted by motor.
  • FIGs. 1 and 2 two processing stages of a press are indicated with 1 and 2, respectively.
  • the upper tool parts 5 and 8 move against lower tool parts 6 and 9 for forming sheet metal parts 11, 11 ′′′.
  • the tools 5, 6 and 8, 9 are interchangeable by means of sliding tables 7, 10.
  • the sheet metal parts 11, 11 ′′′ are transported further by suction spiders 12, 13 in the transfer movements 17, 18.
  • the suction spider 14 serves to transfer the sheet metal part 11 ′′′ to the following clipboard.
  • an intermediate storage is indicated with stencils 16 for storing and removing the sheet metal parts 11.
  • the stencils 16 are by means of adjusting means and movement deflection means, which will be described in more detail below, in e.g. the position shown 16 'movable.
  • the suction spider 12 removes a formed sheet metal part 11 from the processing stage 1 and places it on the stencils 16 in the clipboard 15.
  • the suction spider 13 removes the sheet metal part 11 'previously pivoted in the clipboard 15 and deposits it in the processing station 2.
  • the swiveling movements and correcting movements of the templates 16 take place during the movement of the sheet metal parts 11. During this period, a new sheet metal part 11 'can be inserted in processing stage 1 by means of insertion feeder 19 (FIG. 2).
  • 11 indicates a sheet metal part which is in the transfer movement 17 and which indicates the inclined position of processing stage 1 points.
  • 11 ′′′ a sheet metal part is indicated during the transfer movement 18 in an inclined position for storage in the following processing stage.
  • This new inclined position is caused by a pivoting movement 20 of the templates from the position 11 'in the position 11 ⁇ .
  • the pivoting movement 20 leads to a shift of the center of the sheet metal part 11, which is to be compensated for by a horizontal correction movement 21, movement of the templates in the direction 21 ', and by a vertical correction movement 22, movement of the templates in the direction 22'. Since between the tool 5, 6 of processing stage 1 and the tool 8, 9 of the following processing stage 2 (Fig.
  • FIGs. 4, 5 and 6 a clipboard 15 is shown in detail.
  • a frame 27 is firmly placed on the foundation 26.
  • the frame 27 has guide rails 28 and a motor 29 for the longitudinal movement (horizontally) of a mounting plate 32 that can be displaced in the guide rails 28. With 33 guides of the mounting plate 32 are numbered.
  • a slide plate 36 in guide rails 34 and guides 35 can be moved horizontally, but transversely to the previously described possibility of movement. This movement takes place by means of the motor 37 fixed on the mounting plate 32, a spindle 38 driven by the latter and a nut lock 39 fixed on the slide plate 36.
  • the slide plate 36 carries guide columns 41 in support frames 40, in which guide rods 42 are mounted so as to be vertically movable.
  • a console 45 can be raised and lowered with the guide rods 42.
  • the lifting and lowering movement of the bracket 45 is brought about by a vertical motor 43 arranged on the slide plate 36, the spindle 44 of which engages the bracket 45.
  • a pivot bearing 50 is provided on the bracket 45.
  • an actuating means 51 is pivotally mounted (pivoting movement 20).
  • a second position of the actuating means 51 is indicated by 51 '.
  • the pivoting movement takes place from an adjusting means 47.
  • the actuating means 47 is fastened to the bracket 45 by holding plates 46 and engages the actuating means 51 via the rod 49 and a tab 48.
  • the actuating means 51 engages directly on support brackets 52 for their rotary adjustment about the central axis of the actuating means 51.
  • Template supports 53 are fastened to the support tabs 52 for the templates 16 indicated in a raised position in FIG. 4.
  • Connections 54 are generally positioned at 54 with which the motors or actuating means 29, 37, 43, 47, 51 can be controlled in accordance with the circuit structure mentioned.
