The invention provides a repeated stretching die and belongs to the technical field of dies. The repeated stretching die solves the problem that an existing stretching die is low in production efficiency. The repeated stretching die comprises a lower die plate and an upper die plate. The lower die plate is covered by a discharging plate. A male die body assembly is arranged in the middle of the lower die plate in a penetrating manner and penetrates through the discharging plate. The male die assembly is composed of a plurality of coaxial male die bodies, wherein the male die bodies are mutually connected in a sleeved manner, and every two adjacent male die bodies can relatively move. The end face, facing the lower die plate, of the upper die plate is provided with a male-female die body. A plurality of female die bodies are coaxially arranged in the middle of the male-female die body in a penetrating manner. The female die bodies correspond to the male die bodies in a one-to-one manner. A fixing plate, the upper die plate and the lower die plate jointly define a movement cavity for the female die bodies to move. During stretching, the upper die plate drives the male-female die body and all the female die bodies to move towards the lower die plate, and all the male die bodies are sequentially embedded into the corresponding female die bodies to conduct repeated stretching work until stretching is ended. The repeated stretching die has the advantages of being high in production efficiency and good in product quality.
