Die locking system and method
View Patent ↗A die locking device including a press having a top end, a bottom end and a plurality of channels disposed around a perimeter of the press. The device also includes a plurality of actuators, each of the plurality of actuators affixed to a first end of one of a plurality of locking arms that are each at least partially disposed in one of the plurality of channels. The device also includes a plurality of locking clips, each affixed to a second end of each of the plurality of locking arms and each affixed to one of a plurality of hinges. The plurality of hinges is configured to receive and secure a die stack to the top end of the press.
1. A die locking device, comprising:
a press comprising:
a top end;
a bottom end; and
a plurality of channels disposed around a perimeter of the press;
a plurality of actuators, each of the plurality of actuators affixed to a first end of one of a plurality of locking arms that are each at least partially disposed in one of the plurality of channels;
a plurality of locking clips, each affixed to a second end of each of the plurality of locking arms and each affixed to one of a plurality of hinges;
wherein the plurality of hinges are configured to receive and secure a die stack to the top end of the press.
2. The die locking device of claim 1 further comprising a locking ring disposed between the plurality of hinges and the die stack.
3. The die locking device of claim 1 , wherein the plurality of actuators are hydraulic.
4. The die locking device of claim 1 , wherein the plurality of hinges are pivotally affixed to the top end of the press.
5. The die locking device of claim 1 , wherein the each of the plurality of locking arms is slideably disposed in one of the plurality of channels such that the range of motion of the locking arm is limited to a direction to and from the top and bottom end of the press.
6. A method for die locking, comprising:
placing a die stack in a die locking device, comprising:
a press comprising:
a top end;
a bottom end; and
a plurality of channels disposed around a perimeter of the press;
a plurality of actuators, each of the plurality of actuators affixed to a first end of one of a plurality of locking arms that are each at least partially disposed in one of the plurality of channels;
a plurality of locking clips, each affixed to a second end of each of the plurality of locking arms and each affixed to one of a plurality of hinges; and
wherein the plurality of hinges are configured to receive and secure the die stack to the top end of the press;
monitoring a force exerted by the hinges on the die stack; and
responsively adjusting the position of the plurality of actuators to maintain the force in a desired range.
7. The method of claim 6 , wherein the locking device further comprises a locking ring disposed between the plurality of hinges and the die stack.
8. The method of claim 6 , wherein the plurality of actuators are hydraulic.
9. The method of claim 6 , wherein the plurality of hinges are affixed to the top end of the press.
10. The method of claim 6 , wherein the each of the plurality of locking arms is slideably disposed in one of the plurality of channels such that the range of motion of the locking arm is limited to a direction to and from the top and bottom end of the press.
