Abstract

A press forming method for suppressing wall camber of a side wall portion due to springback of a press-formed product including a top portion, the side wall portion and a flange portion includes: a first forming step of press-forming a preformed part including a flange portion having height continuously changed in an axial direction to have a concave shape, a convex shape or a concavo-convex shape more largely than a target shape of the press-formed product in a height direction to provide a height difference; and a second forming step of press-forming the preformed part into the press-formed product having the target shape to reduce the height difference of the flange portion of the preformed part.
