Description

Technical Field

[0001] The present invention relates to a flipping type forging device for superalloy plates and a forging process thereof. Background Art

[0002] Superalloy is a solid product with metallic properties obtained by mixing and melting one metal with another or several other metals or non-metals and then cooling and solidifying. Due to its high stability and strong anti-deformation ability, it is mainly used to manufacture high-temperature plate load-bearing welded structural parts such as aeroengine combustion chambers and afterburners, large plate structures, plates and wires, etc. Usually, alloy plates are processed through hot forging. Forging technology is a processing method that uses a forging machine to apply pressure to a metal blank, causing it to undergo plastic deformation to obtain a forging part with certain mechanical properties, certain shape and size. In existing forging devices, generally, a forging pressure plate is fixedly installed below a telescopic driving mechanism. When the lower end face of the forging pressure plate is damaged or deformed due to long-term pressing and bumping, it needs to be replaced.
