The invention discloses a die used for twisting a flat steel end head by 90 degrees and relates to a die. The die aims at solving the problems that the manual forming shape and size of a part with theend head twisted by 90 degrees are not stable, the production efficiency is very low, and the requirement for large-batch production cannot be met. The die comprises an upper die assembly and a lowerdie assembly. The lower die assembly comprises a lower die seat, a lower die part and two guiding plates. The upper die assembly comprises an upper die part, a die handle, an upper die seat, a cushion plate and an upper die fixing plate. The lower die part comprises a first lower die and a second lower die. A die handle fixing inner threaded hole is machined in the upper die seat, an upper die part installation counter bore is machined in the upper die fixing plate, the upper die part is a cuboid, and a second rectangular through hole is machined in the bottom end face of the cuboid of the upper die part in the width
