When the briquetted molded part is ejected from the press, the section with the ^ r is.Vv diameter is first ejected in such a way that the remaining .- * sections of the molded part are completely supported until they are ejected. This is then achieved: During the briquetting stroke, all die plates in the press move freely downwards due to the friction between the material to be briquetted and the walls of the die cavity The punch plate is pressed down while at the same time the lower punch plates are held in place with the aid of their associated stop devices. As a result, the top, ie the largest, diameter of the molding is ejected from the die. 3; the die is essentially flush with the topmost i \ U.

Eccentric device for the stamp and guide device for the downward movement of the stamp plates during ejection are housed. There is an upper stamp plate 13, a middle stamp plate 14 and an outer stack plate 15. Ea is been described in the embodiment of a press with three stamp plate; however, a press with any other desired number of punch plates is also possible. A reciprocating male mold 16 (Fig. 7) is operated in the usual way. A fixed punch 17 is provided and, if the object to be produced is to be hollow, can a punch core 18 (Fig.6-10) can be provided. The punch core 18 is mounted axially in the stationary punch 17, and it can be actuated by pressure medium, for example hydraulic, with the aid of a cylinder-piston arrangement. The middle stamp plate 14 and the lower stamp plate 15 are floating, that is, mounted freely movable on heavy guide carriers, not shown, and they can be supported by pneumatic or hydraulic pressure. The top stamp plate 13 is freely moveable on other guide supports. The average stamp plate 14 and the lower punch plate are provided with attachments which are strong enough to carry the entire burden of stress, and there are release devices available for these stop devices which they releasing the desired date ^one!. Ea are stop columns 23 for the middle Stempelplat: provided e 14 and stop columns 24 for the lower punch plate 15 °. The stop pillars 23 are actuated by margin pillars 25. If the spacer pillars 25 abut the stop pillars 23, these are by a

Appropriate device released, whereby äU middle stamp plate 14 for the ejection process nacr. can be pressed down. When spacer columns 26 abut stop columns 24, these are released so that in a similar way the lower stamp plate 15 can be pressed down for the ejecting process. In the embodiment described, the spacer columns 25 are essentially arranged as is the case with the known arrangement, whereas the spacer columns 26 were known to be mounted on the middle stamp plate 14, 3C that this had to be released before the lower oteapel plate 15 could be released. The spacer columns 26 are now also mounted on the upper stamp plate 13 and lead through holes in the middle stamp plate 14.

The spacer columns 25 are adjustable together in the vertical direction, so that a gap A (I'ig.i and 3) can be changed; the spacer columns can also be adjusted together so that an intermediate space B can be adjusted. Let the gap 3 be smaller than the gap A ₁ * so "the lower die plate 15 is released in front of the middle die plate 14, which was previously not possible the press will operate in a known manner and the middle punch plate 14 will be released in front of the lower punch plate 15.

The setting of the spacer columns 25 and 26 depends on the filling setting of the particular tool

addicted. Lie spacer columns 25 are together in a vertical position Direction adjustable in such a way that a ring stack seated in the middle stacking plate 14 is flush with the die in the upper punch plate 13 when the space A is closed. On similar ones V.eisa, the spacer columns 26 can be adjusted together in the vertical direction in such a way that one in the lower ritenpelplatte 15 seated ring stamp flush with the is located in the upper stacking plate 13 die when the intermediate space B is closed. Ground the stacking plates moved into the filling position (Fig. 3, 6, 7, 3 and 9, 10) and requires an outer ring punch 61 a larger material length of pulverized material al3 an intermediate ring punch 62, so must the outer ring stacks 61 mounted in the middle stamp plate 14 move less upwards than the ring punch 62 seated in the lower punch plate, whereby the space B must be smaller than the Gap A, in order to first cause the ring punch 62, which is seated in the lower punch plate, to eject. In this way, if the filling of the stamp plates is set exactly, the sequence when ejecting is accurate depending on the shape of the part to be produced.

The adjustment of the spacer columns is general as already known *. On the front of the machine sit crank handles 30 and 31. The crank handle 30 Uig.4 and 5) sits on a shaft 32, at the other end of which a bevel gear 34 is attached, which with a second Bevel gear 36 meshes with which a pinion 38 is firmly connected sr *.

The ring gear 40 drives gears 42, and the ring gear 41 drives gears 43. Lie gears 42 have internal threads so that their Rotation a vertical displacement of the spacer columns results that have an external thread that goes into the internal thread of the gears 42 engages. In this way, one rotation of the crank handle3 30 results in a rotation of the Gears 42 and thus a displacement of the spacer columns 26, while turning the crank handle 31 a rotation of the gears 43 and thus a displacement of the spacer columns 25 is generated.

(Pig.7); the various ring stacks with their steaspel plates move freely down, eliminating the briquetted Form piece 50 assumes its final shape.

The entire load of the press is taken up by the various stop pillars. At the end of the briquetting stroke, the stamp plates are pressed even further downwards in order to achieve an ejection of the fora piece 50. V / express the F _o rmstück 50 has the recess 51, it is desirable to eject only so much of the largest diameter äe3 fittings, that the bottom of the recess is guided out of the die 60 51st The upper punch plate 13 (Pig.8), in which the die 60 is seated, is pressed down until the upper side 60a is flush with the sole 51a of the recess 51. In this operating position, the associated spacer columns activate the release of the lower punch plate 15, so that the shaped piece is ejected down to the bottom of the outer diameter, at which operating point the upper sides of the die 60, the outer ring punch 61 and the inner ring punch 62 (Fig. 9) lie flush with each other. At this operating point, the stop column for the central punch plate 14 is released, and the die 60 and the ring punches 61 and 62 move downwards together in such a way that a hub section 50c of the molded piece 50 is ejected (FIG. 10). This sequence when ejecting , in which the lower Stecpelplatte 15 is released in front of the middle Etetnpelplatte 14, all parts of the molded piece 50 are fully supported until they are ejected. The punch core 13 (FIG. 10) is finally pulled downwards so that the shaped piece 50 can be removed from the press.

In summary it is as follows: I ^ he AL-standing columns, which release the lower Anscalagvorrich for the different stamp plates, all sit on the upper sterile plate; While the pillars for the next lower stacking plate (in a briquetting press with three stacking plates this is the central stamping plate) only extend between the upper stacking plate and the next lower stacking plate, the spacing columns lead the ones under the second stacking plate Stespelplatter. through openings in this second stacking plate and openings in all the other stamping plates that lie between the topmost stacking plate and that stacking plate, the stop devices of which should release spacer columns. In addition, all barring columns can be adjusted vertically in such a way that in the full ejection position the upper sides of all lower ring columns are flush with the main die.

The embodiment is applicable to a press having any desired number of stacking plates and corresponding punches; By setting up the list of the various stacks, the order in which they are ejected can be changed.
