Method for producing blanks for bladed elements and forging die

摘要

The method involves forging a semi-finished component and machining the semi-finished component by removing material from it. The semi-finished component is forged to approximately the contour of the finished component. Gaps are at least partly produced between at least some blades in the semi-finished component during forging. The semi-finished component can be drop-forged to approximately the contour of finished component. Independent claims are also included for the following: (a) a die for forging semi-finished parts for bladed components, (b) and the use of a semi-finished part for producing bladed components by machining.
