PROBLEM TO BE SOLVED: To provide a tandem press system by which tool changing is performable quickly and which has high productivity. SOLUTION: A tool changing device is formed so that the tool changing device can be carried out and in from a space between a pre-press and a post-press to the outside of a machine in a tool changing direction and can be carried out and independently from the carrying-out and -in on the outside of the machine in the changing direction of a die of a bolster on which the die is set and also two loading/receiving parts which are arranged in parallel in the workpiece conveying direction in the cross bar loading part of the tool changing device and are formed so as to load two cross bars simultaneously and formed so that the present cross bar can be delivered from the workpiece conveying device to the loading/receiving part on one side between the presses during stopping pressing and the next cross bar can be delivered from the other loading/receiving part on the other side to the workpiece conveying device. The tool changing device can be carried out to the outside of the machine and so that, in the outside of the machine, the present cross bar can be demounted from the loading/receiving part on one side and the next cross bar can be loaded to the loading/receiving part on the other side.
