Definitions

  • the invention relates to a lower punch for a tableting machine, which has a Unterstempelschaft on which at least one lower punch insert is arranged.
  • Such parts of a Tabtettierwericmaschines performing lower punches are known and are used in tabletting machines for the production of tablets.
  • the lower punch insert of the lower punch acts in this case with a die which is fixedly arranged on the tableting machine.
  • Such Tablettierwerkmaschines occurs at Unterstempelein accountsn with small diameters or with filigree shapes, the problem that the torque occurring in the production of the tablets on the lower punch shaft can no longer be transferred to the die of the aforementioned known Unterstempelein arrangementsn without the Unterstempelein among break here.
  • a feather key is provided in the known Unterstempein, which is guided in a lower punch guide of the tabletting and thus prevents twisting of the lower punch and the associated torque and / or bending load of the lower punch.
  • Such a tabletting machine is known from document DE 94 16 227 U.
  • the lower punch has an eccentrically arranged and extending in the axial direction of the guide bore, in which a guide pin is immersed, which is arranged fixed in position in a cooperating with the lower die die, so that the guide pin up and down moving lower punch during this stroke movement leads.
  • the measures according to the invention have the advantage that the entire invention Unterstempel Entry, namely arranged in the interior of the lower punch shaft guide bore and cooperating with it guide pin, is disposed substantially completely in the interior of the lower punch in the radial direction, so that for receiving the lower punch according to the invention in known , no own Unterstempel entry having tableting machines no conversion measures are required.
  • This has the advantage that in an advantageous manner also existing, known tableting machines can be equipped with the lower die according to the invention.
  • the embodiment of the lower punch according to the invention thus makes it possible, even in such known tabletting without own Unterstempel Entry now Tablettierwerkmaschinemaschinemaschinee having sensitive inserts to use.
  • An advantageous development of the invention provides that in the lower ram a the at least one Unterstempelrus bearing insert holder, in particular a Unterstempellochplatte is inserted, and that this insert holder has a passage opening for the leading punch shaft guide pin, which in the inserted state with the guide bore of the lower punch shaft flees.
  • Such a measure has the advantage that in the Unterstempeischaft invention of the lower punch different UnterstempeleinA can be used by simply the supporting the Unterstempelein angles insert bracket is replaced.
  • FIG. 1 a tabtaking tool 1 which is known per se and therefore only described in detail is shown, which is divided in a known manner into an upper punch 2, a lower punch 3 and a die 4.
  • the die 4 is in turn fixedly attached in a manner known per se in a tableting machine, not shown, using the tableting tool 1, while the upper punch 2 and the lower punch 3 move up and down during the production process of tablets, pellets or similar compressed ,
  • the lower punch 3 and the upper punch 2 are arranged in corresponding guides of the tabletting machine, the upper punch 2 in the case shown here a key 2 'which cooperates with the upper punch guide of the tableting machine and prevents the manufacturing process, a torque and / or a bending load can occur, which would lead to the one or more upper punch inserts 2a of the upper punch 2, of which only a single one is shown in FIG. 1, would be damaged.
  • lower punch 3 with sensitive lower punch inserts 6 is provided in the described embodiment of the lower punch 3, that in the lower punch shaft 10 of the lower punch 3 of the tabletting 1 an eccentrically arranged and in the axial direction A of the lower punch. 3 extending guide bore 11 is provided, in which a guide pin 12 is immersed, which - as is apparent in particular from Figure 2 - is fixed in the die 4.
  • the lower punch shaft 10 of the lower punch 3 is thus guided in an up and down movement by the fixed in the die 4 guide pin 12, so that a "Ausnicken” of the lower punch inserts 6 bearing lower punch shaft 10, which would lead to an undesirable bending load of the lower punch inserts 6, prevented or at least counteracted.
  • the eccentric, so off-center arrangement of the guide bore 11 causes in cooperation with the fixed to the die 4 guide pin 12 that - since the die 4 in turn is firmly connected to the tableting machine - the lower punch shaft 10 can not rotate during the up and down movement, Thus, no rotational movement about its axis can perform, so that the occurrence of a torque load caused by a rotation about the axis of the lower punch shaft 10, is prevented at the lower punch inserts 6.
  • the dipping in holes 4b of the die 4 lower punch inserts 6 are not located directly on the lower punch shaft 10, but on a - trained here as Unterstempellochplatte 7 - insert bracket. 8 are arranged, which in turn is attached to the lower punch shaft 10. It is provided that the lower punch shaft 10 has a receiving bore 10a into which a guide insert 7a of the lower punch hole plate 7 engages, which is fixed by suitable means in the lower punch shaft 10.
  • the Unterstempellochplatte 7 in this case has a passage opening 14 for the guide pin 12, which is arranged in alignment with the vent opening 18 having a guide bore 11 of the lower punch shaft 10 so that the guide pin 12 can be inserted through the passage opening 14 in the guide bore 11 of the lower punch shaft 10.
  • the guide pin 12 is mounted in the die 4 in a receiving bore 16 and is fixed in position in the die 4 by means of a locking element 17.
  • the guide pin 12 is formed as an integral part of the die 4, but the former training option is preferred because this in a simple manner, a replacement of the guide pin 12, z. b. in case of a defect, is made possible and also known, already existing matrices can be easily retrofitted by the receiving bore 16 is introduced into it.
