Powder press or powder press adapter, and method for operating a powder press
In a powder press, a spacer that is effective between a die plate and an opposite yoke is integrated into the die plate, particularly if the die plate is provided in an adapter, thus increasing the reliability of set-up processes.
1. Powder press or press adaptor for pressing powder comprising a powder press having at least one die carrier, wherein the powder press has at least one counter-yoke that can be displaced relative to the die carrier, comprising at least one of
(a) a spacer that is in effect between the die carrier and the counter-yoke and
(b) a lifting device that is in effect between the die carrier and the counter-yoke,
which spacer or device comprises a cylinder and a piston,
wherein the cylinder surrounds a passage opening through the die carrier or through the counter-yoke,
wherein at least one of the cylinder and the piston surrounds a guide rod,
wherein the piston is disposed in said cylinder, and
wherein a line can apply hydraulic pressure to said cylinder.
2. Powder press or press adaptor according to claim 1 , wherein at least one of the passage opening and the guide rod is parallel to a punch axis.
3. Powder press or press adaptor according to claim 2 , wherein the passage opening surrounds a guide rod.
4. Powder press or press adaptor for pressing powder comprising a powder press having at least one die carrier, wherein the powder press has at least one counter-yoke that can be displaced relative to the die carrier, comprising at least one of
(a) a spacer that is in effect between the die carrier and the counter-yoke and
(b) a lifting device that is in effect between the die carrier and the counter-yoke,
which spacer or device comprises a module within at least one of the die carrier and the counter-yoke,
wherein a line can apply hydraulic pressure to said module.
5. Powder press or press adaptor according to claim 4 , wherein the module is at least one of a cylinder and a piston of the spacer or of the lifting device.
6. Powder press or press adaptor according to claim 4 , wherein at least one of the spacer and the lifting device is configured symmetrically with reference to a passage opening through at least one of the die carrier and the counter-yoke, wherein the passage opening is parallel to a punch axis.
7. Powder press or press adaptor according to claim 6 , wherein the passage opening surrounds a guide rod.
8. Powder press or press adaptor according to claim 6 , wherein the spacer or the lifting device surrounds the passage opening.
9. Powder press or press adaptor for pressing powder comprising a powder press having at least one die carrier, wherein the powder press has at least one counter-yoke that can be displaced relative to the die carrier, comprising a spacer that is in effect between the die carrier and the counter-yoke, which is configured to maintain the distance in a first of its operational states and resiliently in a second of its operational states,
wherein the spacer comprises a piston and a corresponding cylinder, said cylinder surrounding a passage opening through the die carrier or through the counter-yoke, and said cylinder surrounding a guide rod,
wherein said piston is disposed in said cylinder, and
wherein a line can apply hydraulic pressure to said cylinder.
10. Powder press or press adaptor according to claim 9 , wherein the spacer is configured to have a spring action.
11. Powder press or press adaptor according to claim 1 , wherein the spacer or the lifting device is parallel to a punch axis.
12. Powder press or press adaptor according to claim 1 , wherein the spacer or the lifting device has a locking device.
13. Powder press or press adaptor according to claim 1 , further comprising at least two such spacers or lifting devices, which are in effect in parallel.
14. Method for operation of a powder press,
in which a die carrier and at least one counter-yoke that can be displaced relative to the die carrier are held at a defined distance during a first operational state via a spacer or via lifting device as a line applies hydraulic pressure to said spacer or to said lifting device, and
in which the die carrier and the at least one counter-yoke are released, in this regard, during a second operational state, wherein the spacer or the lifting device is released in the direction of the defined distance for the release of the die carrier and of the counter-yoke
wherein said spacer or said lifting device comprises a module within at least one of the die carrier and the counter-yoke, and
wherein said line applies hydraulic pressure to said module.
15. Method according to claim 14 , wherein the spacer is unlocked to release it.
