Abstract
The invention provides tooling and a method for hot forging pieces of sheet metal that are to form metal reinforcement mounted on the leading or trailing edge of a turbine engine blade, by means of bottom and top matrices each presenting a twisted elongate surface for use in shaping an initially plane piece of sheet metal, the shaping surface of the bottom matrix presenting a high portion, a low portion, and two end zones. The bottom matrix includes studs for positioning and guiding the piece, the studs being situated at the periphery of the corresponding shaping surface.
Claims5
A tooling for hot forging pieces of sheet metal that form metal reinforcements mounted on leading or trailing edges of turbine engine blades, the tooling comprising:
- a bottom matrix including a first shaping surface that is a twisted elongate surface;
- a top matrix including a second shaping surface that is a twisted elongate surface;
- wherein the bottom matrix and top matrix are for use in shaping an initially plane piece of sheet metal,
- wherein the first shaping surface includes a high portion, a low portion in a position below the high portion in a vertical direction, and two end zones on opposite sides of the first shaping surface,
- wherein the bottom matrix includes at least three studs extending above the high portion in the vertical direction for positioning and guiding the initially plane piece of sheet metal, the at least three studs being situated at a periphery of the first shaping surface and including:
- a first stud and a second stud positioned at respective end zones of the first shaping surface, and
- a third stud extending from a position in the vertical direction below the low portion of the first shaping surface and having a length greater than respective lengths of the first stud and the second stud.
