Definitions
- Lower punches representing such parts of a tabletting tool are known and are used in tabletting machines for the production of tablets.
- the lower punch insert of the lower punch cooperates with a die, which is arranged in a fixed position on the tabletting machine.
- the problem arises with lower punch inserts with small diameters or with filigree shapes that the torque occurring during the production of the tablets on the lower punch shaft can no longer be transferred from the known lower punch inserts to the die without the lower punch inserts breaking ,
- a key is provided in the known lower punches, which is guided in a lower punch guide of the tabletting machine and thus prevents the lower punch from rotating and the associated torque and / or bending load on the lower punch.
- the lower punch perforated plate 7 has a passage opening 14 for the guide pin 12 which is aligned with the guide bore 11 of the lower punch shaft 10, which has a vent opening 18, so that the guide pin 12 can be inserted through the passage opening 14 into 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.
