"multi-effect" forming tooling for high-temperature forming

Abstract

A forming tooling including a fixed part and a moving part set in action by a one-way press, in a first direction, the tooling varying between an open position and a closed position in which the moving part applies pressure to the fixed part; the moving part including moving dies capable of starting to deform the metal workpiece through a translational movement of the dies in a second direction simultaneous with the translational movement of the dies in the first direction during closure of the tooling, the moving dies being capable of moving away from the metal workpiece through a reverse translational movement of the moving dies, in the second direction, simultaneously with the translational movement of the moving dies in the first direction during opening of the tooling.

1 . A multi-form forming tooling capable of high temperature forming of a metal workpiece, said tooling comprising a fixed part and a moving part to be set in action by a one-way press, in a first direction, said tooling varying between an open position and a closed position in which the moving part applies pressure to said fixed part, wherein said moving part comprises moving dies constructed and arranged to initiate deformation of said metal workpiece through a translational movement of said dies in a second direction simultaneous with the translational movement of said dies in said first direction during said closure of said tooling, said moving dies constructed and arranged to move away from said metal workpiece through a reverse translational movement of said moving dies, in said second direction, simultaneously with the translational movement of said moving dies, in said first direction, during said opening of said tooling. 
     
     
         2 . The multi-form forming tooling according to  claim 1 , wherein said tooling is an isothermal tooling capable of forming at a temperature greater than 850° C. 
     
     
         3 . The multi-form forming tooling according to  claim 1  wherein said fixed part comprises a die presenting two inclined walls capable of displacing said movable dies in said second direction during said closing of said tooling. 
     
     
         4 . The multi-form forming tooling according to  claim 3 , wherein each of said movable dies comprises an inclined face parallel to one of said inclined walls of said die of the fixed part. 
     
     
         5 . The multi-form forming tooling according to  claim 1  wherein said movable part comprises at least one spacer integral with the movements of said moving part capable of moving said movable dies of said workpiece apart in said second direction during said opening of said tooling. 
     
     
         6 . The multi-form forming tooling according to  claim 1 , wherein said fixed part comprises means capable of forming a reference enabling said metal workpiece to be positioned in the tooling. 
     
     
         7 . The multi-form forming tooling according to  claim 1 , wherein said tooling is capable of forming a metal reinforcement for the leading edge or trailing edge of a turbine engine blade. 
     
     
         8 . The multi-form forming tooling according to  claim 7 , wherein each of said movable dies comprises an imprint representative of one of the outer faces of said reinforcement for the leading edge or trailing edge of a turbine engine to be produced. 
     
     
         9 . The multi-form forming tooling according to  claim 6 , wherein said means capable of forming a reference enabling said metal workpiece to be positioned in the tooling includes one or more support plates. 
     
     
         10 . A multi-form forming tooling capable of high temperature forming of a metal workpiece, said tooling comprising a fixed part and a moving part to be set in action by a one-way press, in a first direction, said tooling varying between an open position and a closed position in which the moving part applies pressure to said fixed part, wherein said moving part comprises moving means capable of initiating deformation of said metal workpiece through a translational movement of said means in a second direction simultaneous with the translational movement of said means in said first direction during said closure of said tooling, said moving means being capable of moving away from said metal workpiece through a reverse translational movement of said moving means, in said second direction, simultaneously with the translational movement of said moving means, in said first direction, during said opening of said tooling. 
     
     
         11 . The multi-form forming tooling according to  claim 10 , wherein said moving means include a plurality of moving dies.
