IPC: B21J5/02
Filed: 1983-06-24
Abstract: PURPOSE:To decrease the upsetting load of each forming die and to eliminate the adverse influence on press capacity and life by forming the press-formed inner ring of a constant-velocity universal joint in such a way that the internally burred part thereof is projected at one end in the axial direction. CONSTITUTION:A blank material 24 is axially pressed by means of a lower punch 37 and an upper die 46. As a ram 45 moves downward, the die 46 depresses sectional dies 41-41 together with a holder 34 and moves said dies in the axial center direction between the holder 34 and the die 46 by sliding on slopes 33-33. When the downward movement of the ram 45 is completed, the material 24 is formed to the press-formed inner ring by the punch 37, the six dies 41-41 and the die 46. Since a burred part 22 is produced at one end in the axial direction of the press-formed inner ring, the press-formed inner ring with which the deformation by the blanking load during blanking of the part 22 arises hardly is obtd.
