Abstract

The invention discloses a 2014 aluminum alloy aviation precise hub die forging final forged piece die. The die comprises an upper die and a lower die. The upper die is provided with a first protrusion, a first groove and a first annular inclined plane. The middle portion of the first groove is provided with a second groove, a third protrusion and a first annular gap. A fourth groove is formed in the junction between the first protrusion and the upper die. The first annular inclined plane is provided with a sixth protrusion. The lower die is provided with a die cavity. The die cavity is provided with a second protrusion. The lower die is provided with a first annular groove and a second annular groove. The bottom of the die cavity is provided with a third groove, a fourth protrusion, a second annular gap and a second annular inclined plane. The first annular inclined plane is provided with an upper containing groove. The second annular inclined plane is provided with a lower containinggroove. The second annular inclined plane is provided with a seventh protrusion. Through the structural shape of the 2014 aluminum alloy aviation precise hub die forging final forged piece die, metalflow is rational when a final forged piece is formed, the filling sequence is tend to be more reasonable, and the final forged piece is plump in filling. Accordingly, the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing aviation precision hub die forgings, in particular to a die for the final pressing part of a 2014 aluminum alloy aviation precision hub die forging. Background technique [0002] There is a typical specification forging on a large aircraft, which is the largest forging in the high-strength 2014 aluminum alloy aviation precision hub die forging: half wheel (cabin inner) die forging. The half-wheel (cabin inner side) die forging is a precision die forging, which is a disc type die forging. The maximum outer hub size of the part is φ593.3×309.1mm mm, and the maximum outer contour size of the die forging is φ616.5×314.2mm. [0003] Parts inside the half wheel well such as figure 1 and figure 2 as shown, figure 1 The first side view structural schematic diagram of the 2014 aluminum alloy aviation precision hub die forging provided for the embodiment of the present invention; figure 2 The se...
