  • cylinderpiston-aggregates operated by pressurized fluid.
  • the press ram shown in FIG. 2 is also vertically movable up and down by the action of a hydraulically or pneumatically operated cylinder-piston-aggregate, for example, by having the piston of this aggregate connected with the press ram.
  • the under-part of the press is situated below the press ram and this latter is thereby moved towards the under-part and away therefrom.
  • 1 designates the pressure pad plate which co-operates with the blankholder 3 of a draw -die by means of the bolts 2.
  • the pressure pad plate is tixedly connected to the pressure transmitting member 1a, for instance, by screws.
  • the underpart of the press is shown at 4, on top it is closed .and covered by the plate S which is connected to the press by means of the screws 6a, 6b.
  • the pressure pad plate is resiliently arranged in the hollow space 7 of the under-part of the press 4in order to act resiliently vand elastically on the tool parts chucked or clamped in the press, for example, when a work piece is held during the deformation stroke.
  • the elastic and resilient guidance of the pressure pad plate is effected by providing a pressure medium chamber 8 from the interior of which the pressure pad plate is infiuenced.
  • the purpose of the pressure pad contained within the chamber Sand constituted by the pressure medium consists in to determine the elastic and resilient co-o-peration between the pressure pad plate and the chucked and clamped tool parts.
  • the pressure medium chamber is contained in a cylinder wherein a piston is guided and to which 4a pressure compensating chamber is associated or allotted. As with arrangements according to the invention, this pressure compensating chamber may be provided for simplicitys sake in the upper or lower part of the press itself.
  • the pressure medium chamber is enclosed by a pressure sack 9 consisting of resiliently yielding elastic material, for instance, of artificial material, preferably of the articial material known in the trade as nylon, or of rubber, said pressure sack being accommodated within the hollow space 7 of the under-part of the press.
  • This sack 9 constituting the pressure medium chamber can be filled with air or a non-inhammable gas or gas mixture or eventually even with a fluid, whereby the pressure medium is conveniently ⁇ subjected to a pressure of maximally 7 to 8 atmospheres.
  • the pressure sack In case a less compressible uid is used, the pressure sack must be connected eventually with a supply container by means of a conduit controlled by valves and eventually containing also a pressure regulator by adding a pressure-generator, for instance, a pump, a pressure accumulator such as an air vessel or the like.
  • a pressure-generator for instance, a pump, a pressure accumulator such as an air vessel or the like.
  • the pressure sack 8 On the side opposite from the pressure pad plate 1 the pressure sack 8 is provided with a filling and/or a control device 11 which may be designed, for instance, like a valve.
  • the pressure pad plate has a guide bead 12 along its periphery.
  • This guide bead can be continuous and uninterrupted and thereby run around about the pressure pad plate along its periphery or it can be discontinuous and interrupted by being constituted of several sections lying along the periphery side by side or end to end.
  • the guide bead On its ⁇ side facing the side walls 13a, 13b the guide bead is slightly rounded off as indicated at 14a, 14b so that the pressure pad plate can easily slide up and down according to arrow 15 within the hollow space.
  • the guide bead has a height a which is about the half of the height b of the pressure pad plate and of the pressure transmitting member taken together. Moreover, there is provided such a distance c between the peripheral portion of the pressure pad plate carrying the guide bead and the walls of the hollow chamber serving to guide it that upon loading and exerting a force upon the pressure sack a bead-like projection 16 forms on the sack which serves to guide the pressure pad plate and which penetrates into the space between the pressure pad plate and the walls of the hollow chamber.
  • the advanced position of the tool part or blank holder 3 is indicated in dotted lines at 18. Therefore, with the arrangement according to the invention, the hitherto used cylinders and pistons can be omitted. By this way the pressure pad plate needs absolutely no 'attendance or service since lubrication is no longer required in the ⁇ case no more cylinders and pistons are required.
  • the pressure sack 9' containing the pressure medium chamber 8 is accommodated within the hollow space 7 of the slide or the press ram 4' which contains the pressure pad plate 1 and the pressure transmitting member 1a', said plate acting on the upper part of the tool 3' through the bolts 2', the advanced position of the tool being shown at 17 in dotted lines.
  • the pressure sack 9' is accommodated between the pressure pad plate 1' and the closure wall 10' of the press ram, the side walls 13a', 13b' of which are connected to the plate 5' by means of the screws 6a', 6b.
  • the pressure pad plate has also a bead 12 which may be continuous or discontinuous and may be rounded off in the manner already described (see 14a', 14b), in order that the pressure pad plate can easily slide within the hollow space.
  • the pressure sack 9 of the arrangement according to FIG. 2 is also provided with a filling and control device 11' designed, for instance, valve-like.
  • the arrangement is such that in this case, too, the bead-like projection 16' forming on the sack upon loading of, and acting by pressure upon the pressure sack can penetrate between the pressure pad plate and the walls of the hollow chamber.
  • Another important advantage of the invention can be realized particularly from FIG. 3, namely that the eicient area is considerably greater when using the pressure sack 9' than in known arrangements with cylinders so that even with small pressures a high pad pressure can be obtained.
  • the filling and/ or control devices serve to connect the interior of the pressure sack to a pressure medium source.
  • each pressure sack contains a pressure medium chamber.
