Abstract

The invention provides a die forging forming technology for a GH4169 alloy forge piece to solve the problems that when a hydraulic machine or a counter-blow hammer is utilized for carrying out die forging on the GH4169 alloy forge piece in the prior art, the forge piece is poor in stability and uneven in tissue, and large-depth mixed crystals exist on the surface of the forge piece. The die forging forming technology comprises the first step of feeding bar stock, the step of heating the bar stock to manufacture a blank, the step of carrying out heating and thermal insulation on the manufactured blank before forging, the step of carrying out die forging forming on the blank on which heating and thermal insulation are carried out before forging, and the step of carrying out heat treatment on the die forging formed forge piece. The die forging forming technology is characterized in that a high-power screw press is utilized for carrying out die forging forming on the blank heated before forging.

Description

technical field

[0001] The invention relates to the field of die forging forming technology of GH4169 alloy forgings, in particular to the field of die forging processing of GH4169 alloy forgings for aviation and aerospace engines, and specifically relates to a die forging forming process of GH4169 alloy forgings. Background technique

[0002] GH4169 alloy is widely used in aviation and aerospace fields, mainly used in engine discs, shaft parts, blades and casings, and its application weight accounts for about 50% of the superalloy. Due to the high degree of alloying of GH4169, the forming resistance of forgings is large, the structure and performance requirements of forgings are high, the forging times are required to be as few as possible, and the required forging equipment is required to be as large as possible. At present, the die forging production equipment of GH4169 alloy discs mainly adopts hydraulic press and counter hammer. The stability of forgings in the process ...
