Definitions

  • the invention relates to a powder press and a die plate for a powder press.
  • Powder presses are well known in various embodiments. These usually include at least one fixed on a machine frame die plate with at least one die opening. Each of the at least one die opening is associated with an upper punch and a lower punch, which can be moved into the matrices by suitable drive means, so that powder previously introduced into the dies is pressed in a known manner.
  • the drive can be done here electrically, hydraulically, pneumatically or in any other suitable manner. For example, known as so-called eccentric presses trained powder presses.
  • the invention is therefore an object of the invention to provide a powder press of the generic type and a die plate of the generic type such that in a simple way an exchange of the die plate is possible.
  • the object is achieved by a powder press with the features mentioned in claim 1. Due to the fact that the at least one die plate is locked or can be locked in a defined position by means of a clamping device, it is advantageously possible to position the die plate without tools on the powder press or to remove it from the powder press. This simple installation or removal of the die plate can be replaced, cleaned and / or edited. Also, an exchange of at least one Matrizenö réelle arranged in the die plate matrices, for example, to change a tablet shape and / or tablet size in a simple manner possible.

  • the clamping device or at least part of the clamping device forms a start-up protection for the powder press. This will ensure that the powder press is not put into operation if the die plate is not properly positioned and clamped. The reliability of the powder press is thus significantly increased.
  • a die plate having the features mentioned in claim 11.
  • Characterized in that the die plate comprises means by which the die plate can be arranged by means of a clamping device in a defined reproducible position on a powder press, is advantageously achieved that standardized die plates can be provided which can be locked optionally on different powder presses.
  • a readjustment of the punch that is, the upper punch and / or the lower punch to the die opening is not required, as always achieved by the defined reproducible position of the die plate with respect to the powder press exactly the same positioning.
  • the effort to replace the die plate is expressed by the clamping device, in particular the quick release device expresses low.
  • the die plate by means of a clamping device, in particular a quick-release device, on the machine frame or a bearing block of the machine frame is positionable.
  • a self-adjusting clamping device is used in particular in a simple manner, so that an exact position of the die plate and thus the die opening or the die arranged in the die opening is possible in a reproducible manner.
  • FIG. 1 schematically shows an eccentric press 10, for example a tablet press. Structure and operation of eccentric presses are well known, so that will not be discussed in detail.
  • the eccentric press 10 comprises a machine frame 12 and a bearing block 14 on which a die plate 16 - as will be explained in more detail - is releasably attached.
  • the die plate 16 has an in FIG. 1 non-visible die opening 20 into which via a filling shoe 18 a mass to be pressed can be introduced.
  • the introduced into a die 36 powder mass is then pressed by means of a lower and upper punch, so that a tablet or the like is formed.
  • the eccentric press 10 has the massive machine frame 12, on which a guide 54 for a lower punch and a guide 56 are fixedly arranged for a punch. On the lower guide 54 of the bearing block 14 of the die table 16 is arranged. On the representation of the lower punch and upper punch was omitted for reasons of clarity, with their arrangement is well known.
  • the filling shoe 18 On the top of the die table 16, the filling shoe 18 is movably arranged, on which a dusting device 58 is fixedly mounted.
  • the filling shoe 18 with the device 58 attached to it can be moved back and forth between a parking position A and a filling position B. On the drive of the filling shoe 18 will not be discussed in detail at this point, since this is known per se.
  • the filling shoe 18 has a filling container 60 for the material to be pressed.
  • the filling container 60 is closed with a lid 62, in which an opening is provided, which provides for an atmospheric pressure in the filling container 60.
  • the filling shoe 18 includes a base housing 64 to which the device 58 is attached.
  • the base housing 64 has in its interior a filling opening (not shown) which is oriented towards the surface of the die plate 16 and is positioned in the filling position B of the filling shoe 18 above the die opening 20, so that a filling process with the material to be pressed in known Way is possible.
  • a rotary handle 66 serves, for example, for adjusting filling parameters of the filling shoe 18, which are not to be considered in detail here.
  • FIG. 1a shows a perspective view of the eccentric press 10th
  • the filling shoe 18 is in its parking position A, so that the die opening 20 is openly accessible.
  • the lower punch (not shown) guided in a guide cylinder 68 of the lower punch guide 54 is inserted into the die 16 so far that above its effective punch surface the filled press material into the die opening 20 has a space provided.
  • the upper punch which is displaceably mounted and guided in an adequate guide cylinder 68, can then be pressed with a predetermined force into the die opening 20 from above, so that a tablet is pressed.
  • the top punch is raised to free the work area.
  • the lower punch is also raised until the finished tablet is pushed out of the die opening 20 and lies, for example, in the plane of the upper surface of the die plate 16.
  • the filling shoe 18 is set in motion in the direction of its filling position B, so that the side edge of the dusting device 58 fixedly attached to it pushes and ejects the tablet.
  • FIG. 2 illustrates that the die plate 16 has the die opening 20 into which a die 36, not shown here, can be locked via fastening means 22.
  • the die 36 ultimately determines the shape and size of the tablet to be pressed in a known manner.
  • the die plate 16 is detachably connected to the bearing block 14 via a tensioning device 24.
  • the tensioning device 24 comprises a tensioning lever 26 and a tensioning ring 28, by means of which the releasable connection between the die plate 16 and the bearing block 14 can ultimately be produced.
  • the clamping lever 26 in the direction of arrow 30 is rotatable.
  • FIG. 3 shows a sectional view through the arrangement according to FIG. 2 , It becomes clear that the bearing block 14 has a passage opening 15 through which the lower punch can engage in the die opening 20.
  • the die plate 16 has on its underside, that is, the bearing block 14 side facing locking pins 32 which engage in a receiving opening 17 of the bearing block 14.
  • the pins 32 have outwardly directed U-shaped grooves 19 whose dimensions are matched to the dimensions of the clamping ring 28.
  • the clamping ring 28 engages in the grooves 19 of the pin 32 and locks it, so that the die plate 16 is biased with a clamping force against the bearing block 14 and thus assumes a fixed, defined, unchangeable position.
  • FIG. 4 shows in a schematic perspective view of the arrangement in an unlocked position. It can be seen that the tensioning lever 26 opposite to in FIG. 2 is pivoted (double arrow 30), so that also the clamping ring 28 relative to the pin 32 (FIG. FIG. 3 ) emotional. As a result, the clamping ring 28 is disengaged from the grooves 19 of the pins 32, as in the sectional view in FIG FIG. 5 clarifies is. This is achieved in that the clamping ring 28 seen over its circumference material thicker and weaker material areas forms.
  • FIG. 6 is illustrated how the die plate 16 as shown above, can be removed from the bearing block 14.

  • the die plate 16 can now be removed from the eccentric press 10, for example, to be exchanged for another die plate 16 with another die opening 20. It is also possible to change a matrix 36 arranged in the die opening 20 outside the eccentric press 10 and then subsequently to connect the die plate 16 again to the bearing block 14 via the clamping device 24. This is done in reverse order, that is, the die plate 16 is inserted with the pin 32 in the opening of the bearing block 14.
  • FIG. 7 shows in an exploded view of the structure of the pins 32 which are connected via connecting means, such as screws 34, frictionally with the die plate 16.
  • connecting means such as screws 34
  • FIG. 7 further shows an adjusting ring 38 which is positively and / or non-positively connected to the bearing block 14 via connecting means 40 indicated here.
  • the bearing block 14 forms for receiving the Justierringes 38 a corresponding step-shaped contact surface.
  • the adjusting ring 38 has outwardly facing U-shaped recesses 42, which are adapted in their internal dimensions to the outer dimensions of the pins 32.
  • U-shaped recesses 42 are adapted in their internal dimensions to the outer dimensions of the pins 32.
  • mating surfaces 44 are provided, which lead to a self-aligning positioning of the pins 32 in the Justierring 38, so that the die plate 16 a reproducible reproducible defined position with respect to the bearing block 14 and thus in Reference to the entire eccentric press 10 occupies.
  • FIG. 8 clarifies once again the main components of the illustrated clamping device 24. It is clear that the adjusting ring 38 is fixedly disposed in a corresponding recess of the bearing block 14. The clamping ring 28, as it were, surrounds the adjusting ring 38 and can be moved in or out past the recess 17 of the bearing block 14. In FIG. 8 It is clear that the clamping ring 28 has the weaker material portions 46 and the thicker sections 48. If the weaker material portions 46 in a corresponding position with the pins 32 (in FIG. 8 not shown) and the U-shaped recesses 42 of the adjusting ring 38 are brought, both the die plate 16 and the clamping device 24 can be removed upwards.
