Abstract

A positioning device for hot stamping includes a pilot pin and a driving mechanism for driving the pilot pin. Before a plate material is placed into a press die, when the driving mechanism positions the pilot pin at a predetermined projecting position, a tip portion of the pilot pin projects from a pin guide hole and a body portion of the pilot pin formed further toward a base end side than the tip portion projects from the pin guide hole. Before a process in which the press die removes heat from the plate material after having been press-formed by the press die, when the driving mechanism positions the pilot pin at a predetermined immersed position, the body portion of the pilot pin is immersed in the pin guide hole while only the tip portion of the pilot pin projects from the pin guide hole.
