Research on the Law of Affecting the Quality of forging Metallurgy Quality on the Quality of Wedge Horizontal Rolling Mold

Abstract

Drawing on the traditional and mature cross wedge rolling forming technology for stepped shaft parts, it is innovatively applied to the high-efficiency and low-cost manufacturing of blade preforms with special-shaped sections. Under the action of the rollers, the material undergoes radial compression deformation and axial extension deformation, and the blank changes from a uniform cross-section to a variable cross-section, which is in the shape of a stepped shaft. Forming, to prepare a blade preform with deformed cross-section characteristics. Then, the cooled blade preform is heated again and placed in a precision forging die. Under the action of the unidirectional compressive stress of the upper and lower dies, the blade preform is compressed and deformed, filling the die cavity with the smallest volume, thereby realizing precision forming of blade forgings. In the process parameters of the horizontal wedge rolling mold, the effect of forming angle has the greatest impact on center damage.
