The invention relates to the technical field of metal material machining, in particular to a drawing forcing device and method of a rotary part. The device comprises an upper combined die, a male die, a female die, a female die frame, a lower die, a guide column, a guide sleeve, an ejection rod and an ejection plate. The male die is fixedly connected with the lower end of a lower combined die, the female die is arranged in the female die frame, the female die is fixedly connected with the upper end of the lower die, the lower end of the ejection rod is connected with the ejection plate, and the upper end of the ejection rod penetrates the lower die to be fixedly connected with the female die frame; and the female die is arranged below the male die, and the axis of the male die coincides with the axis of the female die. One end of the guide sleeve is fixedly connected with the upper combined die, and fixedly connected with the lower die, and the other end of the guide column is inserted in the other end of the guide sleeve in a penetrating manner. The method comprises blank manufacturing, blank positioning, blank drawing, blank annealing, die pressure maintaining and mechanical machining. According to the drawing forcing device and method of the rotary part, the problem that in the drawing process of the rotary part, ripping, wrinkling and scrapping are prone to appearing is solved.
