Claims

[Scope of utility model registration request]

In a die set for hot forging that maintains the positional relationship between the upper punch and die by passing a guide shaft hanging down from the upper punch plate through a guide on the die plate side, the guide shaft is connected to two planes that are parallel or approach each other on the center side of the die. The guide is arranged so that the centers of the two planes are aligned on a line in the radial direction with the die center as a reference, and the guide has a non-circular cross section of the two planes that can adjust the clearance between it and the guide axis. A die set for hot forging, characterized in that a guide surface is provided, and flexibility is provided between the guide and the guide shaft to allow relative movement in the radial direction.
