Abstract
A forging assembly may comprise a first die and a second die configured to translate toward the second die. A first sensor may be coupled to at least one of the first die or the second die. The first sensor may be configured to output a first signal correlating to a first distance between the first die and the second die. Additional sensors may be applied to track die alignment during the forging process.
Claims16
A forging assembly, comprising:
- a first die including a first imprint surface, wherein the first die defines a cavity;
- a second die including a second imprint surface and configured to translate toward the first die, wherein the second die further includes a protrusion configured to be received by the cavity;
- a first sensor coupled to the first die and located in the cavity, wherein the first sensor is configured to output a first signal correlating to a first distance between the first die and the second die;
- a second sensor coupled to the first die and located in the cavity, wherein the second sensor is configured to output a second signal correlating to a second distance between the first die and the second die, wherein the first distance is measured in a first direction and the second distance is measured in a second direction orthogonal to the first direction;
- a third sensor coupled to the first die and located in the cavity, wherein the third sensor is configured to output a third signal correlating to a third distance between the first die and the second die, wherein the third distance is measured in a third direction, the third direction being orthogonal to the first direction and to the second direction;
- and
- a magnet affixed to at least one of the first sensor, the second sensor, or the third sensor, wherein the at least one of the first sensor, the second sensor, or the third sensor is magnetically coupled to the first die via the magnet.
