A press forming method, a blank material of a plate-like material, an intermediate molded product, a manufacturing method of a press-formed product, and a press-formed product

摘要

When manufacturing a press-formed product having a protruding portion from a plate-like material, a blank process of punching out from the plate-like material by forming a spare portion on the outer shape of the expanded shape of the press-molded product, and bending the excess portion on a straight side, an intermediate having a bent flange portion A method for producing a press-formed product comprising a first pressing step of forming a molded product, a second pressing step of performing press molding including a projection processing of forming a projection on the intermediate molded product, and a trimming step of trimming the excess skin We propose a method for manufacturing a press-formed product . Provided are a blank material having a spare portion for bending at the straight side that is circumscribed or spaced apart from the contour outline of the expanded shape of a press-molded product, and an intermediate molded product having a bent flange portion bent at the straight side of the spare portion.
