FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and can be used in production of turbine blade stiffness elements. Metal bar is deformed by hot forming through two dies. Note here that mid part is obtained with two wings located on both sides of solid part. Mid part corresponds to the stiffness element base. At the next stage mid part (50) wings are deformed to change the angle of their opening. Final shape of metallic stiffness element is produced.
EFFECT: simplified technology, decreased wastes.
