    The invention relates to a powder press with an upper yoke, a lower yoke and between upper yoke and lower yoke effective tie rods and with a die plate, which is guided parallel to the tie rods and at least one, preferably designed as a lower plate additional plate, which also guided parallel to the tie rods and by means of a cylinder-piston unit with respect to the die plate, the Obeijoch and / or the lower yoke hydraulically adjustable or can be acted upon with a pressure.
    [02] Non-generic powder presses are known, for example, from DE 10 2005 027 296 B3, in which case ultimately several die plates are guided parallel to one another and additional plates, in particular lower plates, are not disclosed. However, generic arrangements are known, for example, from the still unpublished PCT / DE2011 / 002187, where the exact manner in which the additional panels are employed is not disclosed there.
    [03] It is an object of the present invention to provide a generic powder press in which seals of cylinder-piston units, which can make additional plates with respect to the die plate, the upper yoke and / or the lower yoke hydraulically or pressurize as possible be kept free of powder.
    [04] The solution proposed is a powder press having the features of claim 1.
    Here, a powder press with a Obeijoch, a lower yoke and between Oberjoch and Unterjoch effective Zugankem and with a die plate, which is parallel to the tie rods and at least one, preferably designed as a lower plate additional plate, which is also performed parallel to the tie rods and by means of a cylinder-piston unit with respect to the die plate, the Obeijoch and / or the lower yoke hydraulically adjustable or can be acted upon by a pressure, characterized in that the cylinder of the cylinder-piston unit of the die plate and / or from the additional plate pioneering, preferably below the additional plate is arranged.
    [06] In a suitable embodiment, such a powder press can be performed with higher accuracy and have a low overall height. Overall, the powder press can then be designed so that a simple installation and assembly is possible. 2/13 • 9 99 09999 | f • ···· 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 • ········································································ The arrangement of the cylinders away from the die plate and / or from the additional plate is particularly suitable for powder presses with an adapter on which the die plate is provided, which is accommodated on a die receiving plate receiving the adapter and which in turn comprises a top plate of the die plate effective head plate, a foot-side of the die plate effective foot plate and effective between the top plate and the base plate guide for the die plate, wherein the cylinder-piston unit on the top plate, on the base plate or on a rigid supported with the top plate or foot plate connected assembly. Thus, the adapter forms a structurally self-contained and inherently stable unit which has both the die plate and the additional plate, preferably the additional plate formed as a lower plate, displaceable.
    [08] Preferably, the cylinder is arranged on the additional plate, so that - together with the feature that it is pointing away from the die plate or from the additional plate - any gaskets of the cylinder-piston unit also point away from the die plate and thus powder structurally conditioned as far as possible can be kept away from the seals. In particular, this is a basic idea of the present invention can be implemented after the cylinder-piston unit not the piston, but the cylinder to be moved, which ultimately causes a more stable leadership with a suitable design of the rest of the powder press or the other adapter.
    [09] The powder press is particularly compact, when the die plate and the additional plate have a common guide. In this case, in particular, the die plate can lead the additional plate.
    Likewise, the additional plate may carry a further additional plate, so that a particularly stable guidance can be ensured by the leadership of the plates with each other.
    The guide can be further stabilized when the cylinder is part of the additional plate guide, which ultimately can cause the entire powder press is much more compact builds on additional guides or additional guide arms or other guide arrangements, which in particular from radially on Outside arranged guide rods must extend to radially far inside arranged additional plates, optionally omitted or the number and massiveness of such guides can be minimized. 3/13 • • • • • • • • • • • • • • • • • • • • • • Μ
    The piston can, in order to keep the oil requirement to a minimum, be designed to run concurrently with another piston or to be connected in a differential manner.
    Also, the area ratio of two cylinder-piston units 1: 1 can be selected in order to simplify the control behavior in this way. In this context, it is understood that with respect to the area ratio certain tolerances, which can be up to 10%, can be quite tolerated, as this the control behavior is still improved over the prior art.
    [14] It is understood that the features of the solutions described above or in the claims can optionally also be combined in order to be able to implement the advantages in a cumulative manner.
    Further advantages, objects and features of the present invention will be explained with reference to the following description of exemplary embodiments, which are particularly illustrated in the appended drawing. In the drawing show:
    Figure 1 shows a first powder press in a schematic cross section;
    Figure 2 is a horizontal section through the powder press of Figure 1;
    Figure 3 shows a second powder press in a cross-sectionally section and
    Figure 4 shows the powder press of Figure 3 in a horizontal section.
    The powder presses 100, 200 shown in the figures each have an upper yoke 1 and a lower yoke 2 and tie rods 3 (not shown in Figure 3, as well known) to which axially displaceable a die plate 7 is provided, which is arranged in these embodiments of an adapter 6 and held by a Matrizenaufnahmeplatte 4, which in turn is guided axially on the upper yoke 1, lower yoke 2 and tie rods 3 formed press frame.
    The powder presses 100, 200 have punches 5, which are used as an upper punch or lower punch, for example, the lower punch for displacing the Matrizenaufnahmeplatte 4 and the die plate 7 can be used while the upper punch can serve to apply the pressing force.
    [18] In the presently exemplified powder presses 100, 200 of the stamp used as a lower punch 5 by cylinder 8, which are respectively arranged on Obeijoch 1 and lower yoke 2, and piston 9, which are provided on the die plate 4, structurally implemented, wherein both the cylinders 8 and the pistons 9 are through-holes 10 4/13 ····················································································· 4 % • · · · · ·
    surrounded by the upper yoke 1, the lower yoke 2 and the Matrizenaufnahmeplatte 4 and the tie rods 3. This allows a particularly compact design and also here reduces the risk that powder gets to the seals between the cylinder 8 and piston 9, to a minimum.
    [19] While in the embodiment shown in Figures 1 and 2, the upper punch 5 is provided only on Oberjoch 1, in the embodiments shown in Figures 3 and 4, the stamp used as a punch 5 by arranged on Oberjoch 1 and lower yoke 2 cylinder 26th and complementary thereto piston 27, which are each provided on the Matrizenaufnahmeplatte 4, implemented. Here, the cylinder 8, 26 and piston 9, 27 of the punch 5 are each aligned diagonally to each other, as shown in particular in Figure 4. In this way the forces can be applied evenly. In addition, such a designed powder press 200 builds very compact.
    The adapter 6 in turn comprises a top plate 11, a base plate 12 and a guide 13, which is formed in this embodiment by guide rods 14.
    [21] Below the die plate 7, a plurality of additional plates 17, designed as sub-plates, are arranged on the adapter and are likewise guided directly or indirectly on the guide 13. Here, the uppermost additional plate 17 is guided directly on the guide rods 14, while the other additional plates 17 are guided in each case via the upper auxiliary plates 17 guided indirectly on the guide 13.
    The additional plates 17 are each displaceable via cylinder-piston units 18 or acted upon by a pressure. For this purpose, 17 cylinders 19 are provided on each additional plate, which are formed pointing away downwards, so from the respective additional plate 17 and of the die plate 7. As a result, the risk that accumulates on the seals of the cylinder-piston units 18 powder can be reduced to a minimum.
    The cylinders 19 of the upper auxiliary plates 17 also serve to guide the lower auxiliary plates 17, which ensures a particularly compact structure and a compact guide axially with respect to a central axis 23 of the overall arrangement.
    Starting from the cylinders 19, pistons 20 point downwards, in each of which forward flow 21 and return flow 22 to and from the cylinders 19 are provided. In this way, the overall arrangement is particularly compact. On the base plate 12 of the adapter 6, an additional guide 24 formed in the form of guide rods is also provided, which carries clamping and movement cylinders 25, which also can be used for tool mounting. 6.13
