Abstract

A method of applying a marking to a part in a stamping die includes moving a component of the stamping die, the component having a mechanical application device secured thereto. A controlled volume of a marking medium flows through the mechanical application device during the moving such that a volume of the marking medium is controlled by the moving of the component during a stamping die operation. In one form, the component is an upper die of the stamping die.

First claim

What is claimed is:

1 . A method of applying a marking to a part in a stamping die, the method comprising:
moving a component of the stamping die, the component having a mechanical application device secured thereto, wherein a controlled volume of a marking medium flows through the mechanical application device during the moving such that a volume of the marking medium is controlled by the moving of the component during a stamping die operation.

2 . The method according to claim 1 , wherein the controlled volume of the marking medium is not regulated by either an external pneumatic source or an external electrical source.

3 . The method according to claim 1 , wherein the marking medium is thermo-chromatic ink.

4 . The method according to claim 1 , wherein the component is an upper die of the stamping die.

5 . The method according to claim 1 , wherein the component is a lower die of the stamping die.

6 . The method according to claim 1 , further comprising causing an aperture of the mechanical application device to open to release the controlled volume of the marking medium during the stamping die operation.

7 . The method according to claim 1 , further comprising moving the mechanical application device until the mechanical application device contacts the part to create a void defined between the part and a portion of the mechanical application device.

8 . The method according to claim 7 , further comprising releasing the controlled volume of the marking medium into the void.

9 . The method according to claim 7 , wherein the void is surrounded by the portion of the mechanical application device.

10 . The method according to claim 9 , wherein the portion of the mechanical application device is an o-ring or a peripheral ledge.

11 . The method according to claim 1 , wherein the mechanical application device defines an aperture and includes a movable component that is movable to block or open the aperture.

12 . The method according to claim 11 , further comprising moving the movable component away from the part such that the controlled volume of the marking medium is released to the part when the component moves away from the part.

13 . The method according to claim 1 , wherein the controlled volume of the marking medium is supplied by a gravity-feed supply line.

14 . The method according to claim 1 , wherein the controlled volume of the marking medium is supplied by a passive-pressure supply line.

15 . A method of applying a marking to a part in a stamping die, the method comprising:
moving an upper die of the stamping die, the upper die having a mechanical application device secured thereto, wherein a controlled volume of a marking medium flows through the mechanical application device during the moving such that a volume of the marking medium is controlled by the moving of the upper die during a stamping die operation.

16 . The method according to claim 15 , wherein the controlled volume of the marking medium is not regulated by either an external pneumatic source or an external electrical source.

17 . The method according to claim 15 , wherein the marking medium is thermo-chromatic ink.

18 . A method of applying a marking to a part in a stamping die, the method comprising:
moving a component of the stamping die toward the part, the component having a mechanical application device secured thereto, wherein when the component of the stamping die is moved toward the part during a stamping operation, a portion of the mechanical application contacts the part; opening an aperture of the mechanical application device by the part; and releasing a controlled volume of a marking medium through the aperture to the part, wherein the controlled volume of a marking medium flows through the mechanical application device during the moving such that a volume of the marking medium is controlled by the moving during the stamping die operation.

19 . The method according to claim 18 , wherein the controlled volume of the marking medium is not regulated by either an external pneumatic source or an external electrical source.

20 . The method according to claim 18 , wherein the marking medium is thermo-chromatic ink.
