Abstract
This paper was reported deformation of press forming die and mould with rib attachment. At producing the body panels of an automobile, stamping die press process is mainly used. When the press machine produces its, the hitting of upper and lower die is caused by deformation of the press machine and the dies. Dies are processing by the skillful workers, because these errors differ for each press machine. In order to reduce this working, in this study, we made the small press model, and examined the effect of rib attachments in Dies, the effect of the die and mold that processed the bottoming. As a result, the displacement of die and press machine decreases by rib attachments. The displacement can be adjusted by adjusting the position and amount of them.
