FIELD: metallurgy.
SUBSTANCE: inventions relate to forging of metallic parts, particularly parts of irregular shape, for instance gas-turbine engine blades. Die block for forging allows at one surface a half of impression of forged part. At this surface it is located facility providing marking by two directions. Relative to marking it is specified position of impress of forged part. Facility consists of two projecting relative to mentioned surface cushions. Each of cushions allows two grooves, forming two mentioned directions.
EFFECT: facility, providing marking, is used at checking of convergence of two mentioned die blocks for forging after treatment of impressions and after installation of these die blocks in press for forging.
