Abstract

A component comprises a mounting surface to male with another component, a seal channel extending into the mounting surface, and retention tabs extending into the seal channel at or below the mounting surface, wherein the retention tabs are spaced from each other about a perimeter of the seal channel. A method for manufacturing a component comprises producing a component with a seal channel in a flat mate face and mounds of material adjacent the seal channel that extend away from the flat mate face, and deforming the mounds of material to form retention tabs extending into the seal channel.

First claim

What is claimed is:

1. A method for manufacturing a component from a material to have a seal channel with a retention tab, the method comprising:
forming a component from the material to have the seal channel disposed in a flat mate face and a plurality of mounds of the material adjacent the seal channel, the plurality of mounds of the material extending away from and integral with the flat mate face; and
deforming the plurality of mounds of the material to form a plurality of retention tabs extending into the seal channel; and
wherein deforming the plurality of mounds of material comprises flattening the plurality of mounds of material with a punch.

2. The method of claim 1 , wherein:
the punch comprises a flat impact face disposed parallel to the mate face of the cast component; and
flattening the plurality of mounds of material with the punch comprises moving the punch toward the plurality of mounds of material in a direction perpendicular to the flat face and the mate face.

3. The method of claim 2 , further comprising mounting the component in a fixture to hold the mate face parallel to the flat impact face of the punch.

4. The method of claim 1 , wherein the component is formed from a malleable alloy and the plurality of mounds of the material are monolithic with the component such that the component, the seal channel, the flat mate face and the plurality of mounds of the material are formed of a continuous body of the malleable alloy.

5. The method of claim 1 , wherein the component is formed using a hot forming process that uses a molten or softened metal.

6. The method of claim 1 , wherein the plurality of mounds of material are spaced apart from each other at discrete locations along opposing sides of the seal channel.

7. The method of claim 1 , wherein the plurality of mounds of material are spaced apart from each other at discrete locations along a single side of the seal channel.

8. The method of claim 1 , wherein the plurality of mounds of material are spaced apart from each other at irregular intervals.

9. A method for manufacturing a component from a material to have a seal channel with a retention tab, the method comprising:
forming a component from the material to have the seal channel disposed in a flat mate face and a plurality of mounds of the material adjacent the seal channel, the plurality of mounds of the material extending away from and integral with the flat mate face;
deforming the plurality of mounds of the material to form a plurality of retention tabs extending into the seal channel;
deforming a resilient seal strip by pushing the resilient seal strip against the plurality of retention tabs; and
moving the resilient seal strip past the plurality of retention tabs and into the seal groove.

10. The method of claim 9 , wherein the component is formed from a malleable alloy and the plurality of mounds of the material are monolithic with the component such that the component, the seal channel, the flat mate face and the plurality of mounds of the material are formed of a continuous body of the malleable alloy.

11. The method of claim 9 , wherein the component is formed using a hot forming process that uses a molten or softened metal.

12. The method of claim 9 , wherein the plurality of mounds of material are spaced apart from each other at discrete locations along a single side of the seal channel.

13. The method of claim 9 , wherein the plurality of mounds of material are spaced apart from each other at irregular intervals.

14. A method for manufacturing a component having a seal channel with a retention tab, the method comprising:
forming a monolithic component to have:
a flat mate face extending in a plane;
the seal channel extending into the flat mate face; and
a plurality of mounds of material adjacent the seal channel, the plurality of mounds of material extending away from the flat mate face opposite the seal channel; and

deforming the plurality of mounds of material to form a plurality of retention tabs monolithically extending into the seal channel; and
wherein deforming the plurality of mounds of material comprises flattening the plurality of mounds of material with a punch.

15. The method of claim 14 , wherein:
the seal channel extends perpendicularly into the plane in a first direction;
the mound of material extends perpendicularly away from the plane in a second direction; and
each of the plurality of retention tabs extends parallel to the plane.

16. The method of claim 14 , wherein:
the punch comprises a flat impact face disposed parallel to the mate face of the cast component; and
flattening the plurality of mounds of material with the punch comprises moving the punch toward the plurality of mounds of material in a direction perpendicular to the flat face and the mate face.

17. The method of claim 14 , wherein the component is formed from a malleable alloy and the plurality of mounds of the material are monolithic with the component such that the component, the seal channel, the flat mate face and the plurality of mounds of the material are formed of a continuous body of the malleable alloy.

18. The method of claim 14 , wherein the component is formed using a hot forming process that uses a molten or softened metal.

19. The method of claim 14 , wherein the plurality of mounds of material are spaced apart from each other at discrete locations along opposing sides of the seal channel.

20. The method of claim 14 , wherein the plurality of mounds of material are spaced apart from each other at irregular intervals.
