Claims
- 1. A swaging system, comprising:
a movable tool operable to exert force on a die, the die configured to reduce a dimension of a work piece responsive to the exerted force, the dimension reduction having a relationship to a stroke of the movable tool; a sensor operable to obtain information including a measurement of the reduced dimension of the work piece, the sensor operable to generate a measurement signal representative of the obtained information; and a controller operably coupled to receive the measurement signal from the sensor, the controller operable to cause adjustment the stroke of the movable tool responsive to the measurement signal.
- 2. The swaging system of claim 1 wherein the movable tool includes a hydraulic cylinder.
- 3. The swaging system of claim 1 further comprising a plurality of die segments and wherein:
the movable tool is configured to cause the plurality of die segments to converge upon the work piece.
- 4. The swaging system of claim 3 wherein the movable tool further includes a hydraulic cylinder operable to impart axial movement to a drive ring, the drive ring coupled to the plurality of die segments to impart radial movement during said axial movement of the drive ring.
- 5. The swaging system of claim 1 wherein the sensor comprises a laser sensor.
- 6. The swaging system of claim 1 further comprising means for transporting the work piece to a position that is proximate to the sensor.
- 7. A swaging system, comprising:
a movable tool operable to exert force on a die, the die configured to reduce a dimension of a work piece responsive to the exerted force, the dimension reduction having a relationship to a stroke of the movable tool; a stroke control device operable to control the movable tool in accordance with a predefined stroke; a sensor operable to obtain information including a measurement of the reduced dimension of the work piece, the sensor operable to generate a measurement signal representative of the obtained information; a controller operably coupled to receive the measurement signal from the sensor, the controller operable to cause the stroke control device to adjust the predefined stroke of the movable tool responsive at least in part to the measurement signal.
- 8. The swaging system of claim 1 wherein the movable tool includes a hydraulic cylinder and the stroke control device is a hydraulic servo controller unit.
- 9. The swaging system of claim 8 wherein the stroke control device includes a linear velocity displacement encoder.
- 10. The swaging system of claim 7 further comprising a plurality of die segments and wherein:
the movable tool is configured to cause the plurality of die segments to converge upon the work piece.
- 11. The swaging system of claim 10 wherein the movable tool further includes a hydraulic cylinder operable to impart axial movement to a drive ring, the drive ring coupled to the plurality of die segments to impart radial movement during said axial movement of the drive ring.
- 12. The swaging system of claim 7 wherein the sensor comprises a laser sensor.
- 13. The swaging system of claim 7 further comprising means for transporting the work piece to a position that is proximate to the sensor.
- 14. A method of performing a swaging operation on a plurality of work pieces, comprising:
a) employing a swager to reduce a dimension of a first work piece, the dimension of the first work piece having a first value; b) obtaining information regarding a measurement of the dimension of the first work piece; and c) employing a swager to reduce a dimension of a second work piece, the dimension of the second work piece having a second value, a difference between the first value and the second value based at least in part on the obtained information.
- 15. The method of claim 14, wherein
step a) further comprises using a first stroke of a movable tool to reduce the dimension of the first work piece; and step c) further comprises using a second stroke of the movable tool to reduce the dimension of the second work piece, a difference between the first stroke and the second stork based at least in part on the obtained information.
- 16. The method of claim 15 wherein step a) further comprises employing a hydraulic cylinder to cause movement corresponding to the first swaging stroke.
- 17. The method of claim 16 wherein step a) further comprises controlling the movement of the hydraulic cylinder using a stroke length control device.
- 18. The method of claim 16 wherein step a) further comprises controlling the movement of the hydraulic cylinder using a hydraulic servo controller device.
- 19. The method of claim 14 further comprising, before step b), moving the first work piece to a sensor device operable to generate information regarding a measurement of the dimension of the first work piece.
- 20. The method of claim 14 wherein the dimension of the first work piece comprises an outer diameter of the first work piece and the dimension of the second work piece comprises an outer diameter of the second work piece.
