Definitions

  • the invention relates to a press system according to the preamble of claim 1 and claim 4.
  • Sheet metal parts are processed in such a press system in several processing steps.
  • the need to reduce investment and operating costs led to the merging of the processing steps carried out on individual presses in press lines into compact, multi-stage multi-stand presses.
  • FIGS. 1A to 1F The previous development direction of such press systems is shown in FIGS. 1A to 1F in DE 39 05 069.
  • the aim of the invention is to significantly reduce the investment costs and operating costs of such press systems. According to the object of the invention, this goal should be achievable by reducing the number of components and by taking over - integrating - multiple functions into remaining components.
  • the press system shown has a head piece 1 which extends over the working stages 6.
  • the head piece 1 is supported on press stands 2 which are set up on the foundation 12 by means of crossbeams 3. These components of the press system are clamped by means of tension anchors 4.
  • a press table 5 is placed on the crossbeams 3.
  • a sliding table 11 with a lower tool part 10 or a set of lower tool parts is pushed onto this.
  • an outer tappet 7 is initially mounted on the press stands 2 by means of guides 23 in guides 22 (FIG. 4) and can be raised and lowered via connecting rods 17.
  • the outer tappet 7 extends over several work stages 6.
  • the drive or the tappet is carried out via motor-driven gears 19, 20 in the head piece 1.
  • a conversion device extends for those to be moved from work stage 13, 6 to work stage 6 Sheet metal parts made from e.g. in the cycle of the tappet / press system, there are rocking levers 14 which engage rails 15, which carry gripping tools 16 or which directly engage gripping tools 16, which can be suction bars.
  • a drawing stage upstream of the working stages 6 is numbered with a ram 36, an upper tool part 37 and a lower tool part 38.
  • an intermediate storage 42 is arranged which halves the distance between these processing stages.
  • the invention provides two possibilities here, the first embodiment relating to the direct engagement of the connecting rods 17 on the outer tappet 8 according to FIG. 2.
  • the second embodiment according to FIG. 6 provides for each of the e.g. Four articulation points 40 of the connecting rods 17 on the tappet, here 39, provide protection in the form of an overload protection 41.
  • the connecting rods 17 are connected to a pressure piston 44 in the respective articulation point 40.
  • the pressure chamber 43 provided below the pressure piston 44 is set to a defined pressure level for the press operation via a pressure line 33.
  • the outer plunger 7 can be seen, in which four inner plungers 8 are used, corresponding to the number of working stages 6.
  • the inner plungers 8 are supported by guides 24 in the outer plunger 7 so that they can be raised and lowered.
  • Fig. 4 shows that the centers of the connecting rods 17 and the centers of the tension anchors 4 located on opposite sides of the press system are arranged on a common line 21 in order to achieve favorable loading and force application points.
  • Line 21 is a horizontal line and runs transversely / perpendicular to the direction of the press run.
  • the direction of press travel - the direction of transport of the workpieces - is positioned at 35.
  • each inner tappet has 8 bracket plates 34, on each of which a spindle 32 is rigidly fastened, which points in the upward direction.
  • the spindle 32 interacts with a worm wheel 31 which can be rotated by a motor-driven worm 30 in the manner of a nut-spindle connection for adjusting the height of the tool placed on it.
  • the piston 29 of a pressure cylinder 27 rests on the worm wheel 31.
  • a pressure chamber 28 is provided above the piston 29 and is pressurized via the pressure line 33 in the operating state of the press system.
  • the worm, worm wheel and spindle solution (30, 31, 32) enables the setting of the inner plunger 8 in the outer plunger 7.
  • the height adjustment 26 of the tools can thus be carried out via these means.
  • the pressure cylinder 27, pressure chamber 28, piston 29 and spindle 32 solution enable the working stages to be protected in the event of an overload as an overload protection 25.
