Method of manufacturing press-formed product, and tray and hot-press manufacturing line used for manufacturing press-formed product

Abstract

A method of manufacturing a press-formed product includes a heating step, a transportation step, and a pressing step. At the heating step, a sheet-shaped heat storage member 5 and a sheet-shaped workpiece W1 placed above the heat storage member 5 are heated by a heating device 14 while overlapping in the direction normal to the sheet surfaces of the workpiece W1. At a first transportation sub-step, the heat storage member 5 and the workpiece W1 placed above the heat storage member 5 are transported from the heating device 14 to a lifting location while overlapping in the direction normal to the sheet surfaces of the workpiece W1. At a second transportation sub-step, the workpiece W1 placed above the heat storage member 5, when at the lifting location, is lifted upward by a transportation device 46 and transported to a pressing location on a press machine 20. At the pressing step, the workpiece W1 is processed by the press machine 20.
