Problems solved by technology

[0003] Due to the structure of the tenon blade, the rolling process and the characteristics of the superalloy, it is difficult to control the uniformity and grain size of the three parts of the tenon, transition zone and airfoil profile. In the prior art, there are precision cold rolling High-pressure compressor blade manufacturing method, but its wool forming method and the entire process route need to be improved

Abstract

The invention provides a die in an alloy blade precision forging process, and particularly provides a rod squeezing die and a forging die. The die is characterized in that the rod squeezing die comprises an ejector rod (1), an ejector rod guide sleeve (2), a cushion block (3), an insert (4), a squeezing cylinder (5) and a punch head (6); and the forging die comprises a male die (10) and a female die (20). The blanking die squeezing die and forging die are adopted for blanking so as to realize precision forging with the blade singe-face allowance of 0.3-0.7mm, the requirements of a cold rolling process on processing allowance, size precision and surface quality of forge pieces are met, the metal streamline direction of a blade body is reasonable, and the mechanical properties and the use performance of the blade are improved.

Description

technical field [0001] The invention relates to the field of precision forging of high-temperature alloy blades, in particular to a rod-extrusion die and a pier die for blank-making dies for blades without allowance. Background technique [0002] In the manufacturing process of advanced aeroengine compressor blades, since the compressor blades are characterized by large edge plates, thin airfoil profiles, and small front and rear edge thicknesses, the alloying degree of blade materials is high, and the subsequent process of blade supporting processing is cold roll The rolling process has high requirements on the machining allowance, dimensional accuracy and surface quality of forgings. These factors increase the difficulty of blade forging, so blade forging requires a new technology. [0003] Due to the structure of the tenon blade, the rolling process and the characteristics of the superalloy, it is difficult to control the uniformity and grain size of the three parts of th...
