PROBLEM TO BE SOLVED: To provide a forging processing device capable of preventing an increase in the process number and an increase in a shaving margin.SOLUTION: The present invention aims at a forging processing device for molding a forging processing product 9 by driving a punch 6 in a forging raw material installed in a die 1. The die 1 comprises a die body 2 having a molding hole 21 for storing the forging raw material and providing a side part restraining surface 22 for restraining an outer peripheral side surface of the forging raw material on an inner peripheral side surface of its molding hole 21 and an anvil 3 arranged on the undersurface side of the die body 2 so as to block up the lower end of the molding hole 21 and providing a bottom part restraining surface 32 for restraining a bottom surface of the forging raw material in a position corresponding to the molding hole 21 on an upper surface. A gas release groove 7 is formed on the upper surface of the anvil 3, and in an upper side opening part 70 in the gas release groove 7, one end 71 is opened on the bottom part restraining surface 32 as a gas release port 72, and the upper side opening part 70 of the gas release groove 7 is blocked up by a lower end surface of the die body 2 except for its gas release port 72.SELECTED DRAWING: Figure 1
