The invention relates to an escalator step circular hole outer link pressing and riveting tool die. The escalator step circular hole outer link pressing and riveting tool die is formed by an upper die assembly and a lower die assembly; the upper die assembly comprises an upper die block, an upper fixing plate is arranged in the center of the bottom face of the upper die block, two pressing and riveting blocks are arranged on the bottom face of the upper fixing plate, and the two sides of the upper die block are provided with guide sleeves in a fixed mode. The lower die assembly comprises a lower die block, the center of the top face of the lower die block is sequentially provided with a base plate and a lower fixing plate from inside to outside, the two sides of the lower die block are provided with guide columns in a fixed mode, and the guide columns are matched with the guide sleeves. Two installation holes are formed in the lower fixing plate, and two positioning pins are arranged between the two installation holes. By means of the escalator step circular hole outer link pressing and riveting tool die, the head of a pin shaft can be pressed and riveted while single link plate pressing work is achieved, link plate pressing and pin shaft pressing and riveting can be completed at a time, and the pressing and riveting coincidence and the production efficiency are improved.
