Abstract
A nozzle includes a tube and a flared deflector extending coaxially from an outlet thereof. A stream of abrasive pliant shot is discharged through the nozzle and deflected radially outwardly from the deflector for abrading a shifting edge along an aperture in a workpiece surface.
Claims19
An abrasive shot nozzle comprising a tube having an inlet and outlet disposed coaxially at opposite ends thereof, and a flared deflector extending coaxially from said outlet for deflecting radially outwardly therefrom a stream of abrasive pliant shot channeled axially straight through said tube from said inlet, and said tube and deflector have hardened flow surfaces for resisting abrasion thereof from said shot stream.
A method of using an abrasive shot nozzle including a tube and a flared deflector extending coaxially from an outlet thereof for deflecting a stream of abrasive pliant shot radially outwardly therefrom, comprising:
- channeling said shot in a stream of carrier fluid through said nozzle;
- and
- positioning said nozzle substantially perpendicularly to a workpiece having a shifting edge adjoining a surface thereof to direct said shot stream at a shallow angle of incidence with said surface and substantially normal to said edge.
A nozzle comprising:
- A tube having an inlet and outlet at opposite ends thereof, a converging bore extending from said inlet to a throat, and a diverging bore extending from said throat to said outlet;
- a support rod extending coaxially through said converging and diverging bores and out said outlet;
- and
- a flared conical deflector fixedly joined to a distal end of said rod outside said tube outlet for deflecting radially outwardly a stream of abrasive pliant shot discharged from said tube outlet.
An apparatus for treating edges of a plurality of circumferentially spaced apart apertures bordering a surface in a disk, comprising:
- means for rotating said disk;
- a nozzle including:
- a tube having an inlet and outlet at opposite ends thereof, a converging bore extending from said inlet to a throat, and a diverging bore extending from said throat to said outlet;
- a support rod extending coaxially through said converging and diverging bores and out said outlet;
- and
- a flared conical deflector fixedly joined to a distal end of said rod outside said tube outlet;
- and
- means for channeling a stream of abrasive pliant shot in a carrier fluid through said nozzle for discharge from said outlet thereof radially outwardly along said deflector.
