The hexagon head punching die of the traditional bolt generally comprises a die core and a die shell, wherein the die core is of an integral hexagon structure, the forming inner angle of the die core is easy to crack in the use process, the die changing frequency is high, and the bolt processing cost is increased. For this reason, the existing die core has a structure as shown in fig. 1, and is formed by combining six die core pieces 51, dividing the die core 50 at the forming inner corners, relieving stress concentration, and effectively preventing the die core from cracking, wherein the service life of the die core is more than 10 times that of the conventional die core, and 200 ten thousand die cores (the service life of the die is represented by the processing number of bolts) are obtained by processing the hexagon heads with the opposite sides of 7.8 mm.
