Abstract

A system for screening deburring media during deburring operations of a hardware part comprises a deburring machine comprising a media slurry basin, a deburring media slurry disposed in the media slurry basin, and a media screening device freely movable within the deburring media slurry to define a dynamic zone of capture to capture noncompliant media. The media screening device can comprise a housing defining an inner chamber, and can comprise a plurality of openings each sized to restrict compliant deburring media from passing through the opening, and each opening sized to permit passage of noncompliant deburring media into the inner chamber. Each opening can comprise a counterbore. The media screening device can comprises at least one removable housing body removably coupled to the housing to facilitate removal of captured noncompliant deburring media. A method is disclosed for screening deburring media during deburring of a hardware part.

First claim

What is claimed is:

1. A system for screening deburring media during deburring operations of a hardware part, comprising:
a deburring machine comprising a media slurry basin;
a deburring media slurry disposed in the media slurry basin, the deburring machine operable to agitate the deburring media slurry;
a media screening device freely movable within the deburring media slurry to define a dynamic zone of capture, the media screening device configured to capture noncompliant deburring media, the media screening device comprising a housing defining an inner chamber and having a plurality of openings, each opening sized to restrict compliant deburring media from passing through the opening, and each opening sized to permit passage of noncompliant deburring media into the inner chamber, thereby capturing the noncompliant deburring media within the media screening device, wherein each opening comprises an outer opening area and an inner opening area, wherein the outer opening area is sized larger than the inner opening area, and wherein at least some of the openings comprise an extended opening portion extending from an inner surface of a wall of the housing into the inner chamber.

2. The system of claim 1 , wherein the media screening device comprises at least one housing enclosure removably coupled to the housing to facilitate removal of captured noncompliant deburring media.

3. The system of claim 1 , wherein the deburring machine comprises a tub-type deburring machine configured to agitate the deburring media slurry generally around a horizontal axis and generally in a wave motion, and wherein the media screening device comprises a generally cylindrical housing configured to move generally around the horizontal axis and to rotate around its own horizontal axis.

4. The system of claim 1 , wherein the deburring machine comprises a bowl-type deburring machine configured to agitate the deburring media slurry around a vertical axis and generally in a whirlpool motion, and wherein the media screening device comprises a generally spherical housing configured to move generally around the vertical axis and to rotate about its own axis.

5. The system of claim 1 , wherein the media screening device is configured to capture noncompliant media in real-time during a deburring operation of a hardware part.

6. The system of claim 1 , wherein the media screening device is unattached to the deburring machine.

7. A method for screening deburring media during deburring of a hardware part, comprising:
introducing media slurry into a deburring machine;
introducing a media screening device into the deburring media slurry, the media screening device freely movable within the deburring media slurry to define a dynamic zone of capture, the media screening device comprising a housing defining an inner chamber and having a plurality of openings, each opening sized to restrict compliant deburring media from passing through the opening, and each opening sized to permit passage of noncompliant deburring media into the inner chamber, thereby capturing the noncompliant deburring media within the media screening device, wherein each opening comprises an outer opening area and an inner opening area, wherein the outer opening area is sized larger than the inner opening area, and wherein at least some of the openings comprise an extended opening portion extending from an inner surface of a wall of the housing into the inner chamber; and
operating the deburring machine to move the media screening device about the deburring media slurry, thereby facilitating capture of noncompliant media in the media screening device.

8. The method of claim 7 , further comprising:
removing the media screening device from the deburring media slurry;
removing the noncompliant media from within the media screening device; and
re-introducing the media screening device into the deburring media slurry.

9. The method of claim 7 , further comprising introducing a hardware part into the media slurry, and maintaining the hardware part in the deburring media slurry with the media screening device during a deburring process, thereby maintaining a single production flow of the hardware part.

10. The method of claim 7 , further comprising deburring a hardware part and screening the media slurry with the media screening device simultaneously in real-time.

11. The method of claim 7 , further comprising facilitating free movement of the media screening device about the deburring media slurry, whereby the media screening device is unattached to the deburring machine.

12. A media screening device operable with a deburring machine, comprising:
a housing comprising at least one wall defining an inner chamber, and configured to be freely movable about a deburring media slurry of a deburring machine;
a plurality of openings disposed through the at least one wall, each opening comprising an outer opening area and an inner opening area, wherein the outer opening area is sized larger than the inner opening area, and wherein the inner opening area is sized to restrict compliant deburring media from passing through the inner opening area opening, and sized to permit noncompliant deburring media to pass through the inner opening area, thereby capturing the noncompliant deburring media within the inner chamber, wherein one or more of the openings comprises an extended opening portion extending from an inner surface of the wall into the inner chamber; and
at least one removable housing enclosure removably coupled to the housing to facilitate removal of captured noncompliant deburring media.

13. The media screening device of claim 12 , wherein the plurality of openings are radially formed through the at least one wall.

14. The media screening device of claim 12 , wherein each opening comprises a counterbore formed through the at least one wall.

15. The media screening device of claim 12 , wherein the outer opening area is sized to trap at least some noncompliant media before passing through the inner opening area.

16. The media screening device of claim 12 , wherein the housing comprises a generally cylindrical housing.

17. The media screening device of claim 12 , wherein the at least one removable housing enclosure comprises an end cap removably coupled to an end of the generally cylindrical housing.

18. The media screening device of claim 12 , wherein the at least one removable housing enclosure comprises a first housing body and a second housing body defining the housing, wherein the first housing body is removably coupled to the second housing body to facilitate removal of the noncompliant media captured in the inner chamber.

19. The media screening device of claim 12 , wherein the housing comprises a generally spherical housing.

20. The media screening device of claim 19 , wherein the at least one removable housing body comprises a cover removably coupled to the housing to facilitate removal of the noncompliant media captured in the inner chamber.
