Abstract (en)
[origin: WO2012152687A1] Hot extrusion process and tool for producing a metal part (1), such as a landing gear, possessing a flow stress of 200 MPa or more when cold and comprising a tubular portion (2) one of the two ends of which is extended by a complex shape (3), said process comprising, after heating and hot transfer of the billet (11) to an extrusion press (6): at least one direct extrusion step using a first mandrel (4) in order to produce the complex shape (3); and at least one indirect extrusion step with a second mandrel (5) replacing the first, the second mandrel moving in the same direction and in the same way as the first mandrel (4) in the same extrusion tool (6) so as to produce all of the tubular portion (2) of the part (1).
