摘要

in addition to the pressure to gesenkformen, upset, when a gesenkformen is performed, a pressure in the direction which is the same as the direction of the holding power, the gesenkgeformten section (8b) is carried on a druckaufnahmerandabschnitt (8y) l agerhalters (8) by the pressure applied by the gesenkformrolle (24) is provided.as a result, the elastic deformation in a umfangswandabschnitt (8c), which is not bent, and the extent of increase elastic deformation of the lagerhalters (8) in the axialrichtung is reduced, so that it is possible, the difference of the amount of elastic deformation between the stockholders (8) and an outer ring (14a) to increase.thus, the axial residual stress in the warehouse (8) after the gesenkformen is finished, compared to the case of ordinary gesenkformens increased. therefore, it is possible to keep the safety of auu00dfenrings (14a) to increase.
