Definitions
- the invention relates to a press system according to the preamble of claim 1.
- Sheet metal parts are processed in such a press system in several processing steps.
- the aim of the invention is to reduce the investment costs and operating costs of such press systems significantly lower. According to the object of the invention, this aim is to be achieved be by reducing the number of components and by taking over - integrating - Multiple functions in remaining components.
- the compact, short press system with the elimination of clipboards is an advantage here and reducing the press drive elements.
- the press system shown has a head piece 1 that extends over the work stages 6 extends.
- the head piece 1 is supported on press stands 2, which cross beams across the stand 3 are placed on the foundation 12. These components of the press system are braced by means of tension anchors 4.
- On the column cross members 3 is a Press table 5 put on.
- On this is a sliding table 11 with a lower tool part 10 or set of tool lower parts pushed.
- In the upper area of the press system is an outer plunger 7 by means of guides 23 in guides 22 (Fig. 4) the press stands 2 stored and can be raised and lowered via connecting rods 17.
- the outer plunger 7 extends over several work stages 6.
- the drive of the or the tappet is carried out via motor-driven gears 19, 20 in the head piece 1.
- a transfer device for the work stage extends through the entire press system 13, 6 to work stage 6 sheet metal parts to be moved, which e.g. to the beat of Ram / press system driven rocker arms 14, which on rails 15th attack, the gripping devices 16 or directly to gripping devices carrying means 16, the Can be sucker bars, attack.
- a drawing stage upstream of the working stages 6 is numbered with one Drawing plunger 36, an upper tool part 37 and a lower tool part 38.
- an intermediate storage 42 is arranged halved the distance between these processing stages.
- the connecting rods 17 engage in the articulation points 18 and 40, as shown in FIGS. 2 and 6 is illustrated in more detail on the outer plunger 7 or the plunger 39.
- the invention sees Here are two options, with the first design focusing on the direct attack the connecting rod 17 on the outer tappet 8 corresponds to FIG. 2.
- the second embodiment 6 sees for each of e.g. four articulation points 40 of the connecting rods 17 on the Ram, here 39, 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 one below of the pressure piston 44 is provided for the press operation over a pressure line 33 is set to a defined pressure level.
- the outer plunger 7 can be seen in the corresponding to the Number of working stages 6, here four inner plungers 8 are used.
- the inner tappets 8 are by means of guides 24 in the outer plunger 7 mounted and lowered.
- Fig. 4 shows that the centers of the connecting rods 17 and the centers of the opposite Tension anchors 4 located on the sides of the press system on a common one Line 21 are arranged to achieve favorable load and force application points.
- Line 21 is a horizontal line and runs transversely / perpendicular to the direction of the press run.
- the press flow direction - transport direction of the workpieces - is positioned at 35.
- each inner plunger has 8 console plates 34 on each of which a spindle 32 is rigidly attached, which in the direction of points above.
- the spindle 32 acts with a worm 30 driven by a motor rotatable worm wheel 31 in the manner of a nut-spindle connection for height adjustment of the placed tool together.
- On the worm wheel 31 is the Piston 29 of a pressure cylinder 27.
- a pressure chamber 28 is located above the piston 29 provided that in the operating state of the press system with pressure via the pressure line 33 is applied.
- the worm, worm wheel, spindle solution (30, 31, 32) enables the setting the inner plunger 8 in the outer plunger 7.
- the height adjustment is thus via these means 26 of the tools can be carried out.
- the pressure cylinder 27, pressure chamber 28, piston 29 and spindle 32 solution enables the work stages to be protected in the event of an overload as overload protection 25.
