The utility model discloses a prestress pre-tensioning method integrated steel die used for bird-shaped plate production. The prestress pre-tensioning method integrated steel die comprises a left side die, a right side die, two box-shaped steel columns, a front stretching bed, a rear stretching bed and a bottom plate arranged between the two side dies. Each side die comprises a steel die plate, transverse main edges, stand columns, two longitudinal rods and a plurality of transverse rods, wherein the transverse rods and the longitudinal rods are all arranged below the steel die plate, the two ends of each transverse rod are connected with the two longitudinal rods respectively, the lower end face of the steel die plate is supported by the transverse main edges, the transverse main edges are arranged over the transverse rods respectively, the upper ends of the stand columns are connected to the transverse main edges, and the lower ends of the stand columns are connected to the transverse rods or the longitudinal rods. The front end and the rear end of each box-shaped steel column are connected to the two stretching beds respectively. The two box-shaped steel columns are arranged below the steel die plates of the two side dies respectively, located above the transverse rods and arranged on the outer sides of the vertical sections of the transverse main edges. The prestress pre-tensioning method integrated steel die is simple in overall structure, convenient to obtain and low in cost. Manual work, construction periods and material input can be reduced when the prestress pre-tensioning method integrated steel die is applied, and the influences of stretching stress on the steel die can be eliminated.
