The invention discloses a signboard punch forming die and a punching machine and relates to the technical field of die machining. The signboard punch forming die and the punching machine are designed for solving the problems that a signboard product is low in machining efficiency and poor in assembling consistency. The signboard punch forming die comprises an upper die seat, a lower die plate, a collecting device and a lower cushion plate, all of which are sequentially arranged from top to bottom. A forming punch is fixedly installed below the upper die seat, and the punching stroke of the forming punch is larger than the thickness of the lower die plate. A groove is formed in the upper surface, fixedly connected with the lower die plate, of the lower cushion plate. The collecting device comprises a colleting material belt arranged in the groove, an unrolling device arranged in the feeding direction of the collecting material belt, and a rolling device arranged in the discharging direction, wherein the sticky surface of the collecting material belt is arranged upwards. The signboard punch forming die is suitable for manufacturing signboard products and collecting the signboard products.
