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.
