# Method of manufacturing press-formed product, apparatus for transporting heated workpiece, and hot-press manufacturing line

## Abstract

A method of manufacturing a press-formed product includes: a heating step; a transportation step; and a pressing step. The transportation step includes: using claws of a pair of first arms to support the lower surface, at both ends, of a first heated workpiece and lift the workpiece; using claws of a pair of second arms to support the lower surface, at both ends, of a second heated workpiece and lift the workpiece; transporting the first heated workpiece with the lower surface supported, at both ends, by the claws of the pair of first arms and the second heated workpiece with the lower surface supported, at both ends, by the claws of the pair of second arms, where the first and second heated workpieces overlap each other in the direction normal to the sheet surfaces; driving the pair of first arms to lower the first heated workpiece to a pressing location on a press machine; and driving the pair of second arms to lower the second heated workpiece to a pressing location on the press machine.
