The invention relates to a manufacturing method for a pipe die by using a steel ingot great-reducing-forming blank, comprising the following steps of: steel ingot smelting, steel ingot reinspection, circular furnace heating, hydraulic pressure punching, great reducing perforation, periodical pipe rolling, manual initial inspection, straightening, roughly machining, ultrasonic flaw detection, thermal treatment, physical and chemical inspection for keeping quality up to standard, finely machining, magnetic particle inspection, manual reinspection, packaging and putting into storage, wherein the steel ingot material 21CrMo10 is adopted, during great reducing perforation, a bottle blank (5) is obliquely rolled and subjected to great reducing perforation by using a tapered roller (6) and an ejector header (7) to obtain a hollow billet 8, and after the reducing perforation, the external diameter of the hollow billet 8 is 10mm larger than the external diameter of the socket end of the pipe die. The manufacturing method is combined with a hydraulic pressure punching technique, a tapered roller great reducing perforation technique, a periodical pipe rolling machine forging and rolling technique and other techniques, the whole blank of the pipe die can be kept to have the performance similar to that of a forge piece and a pilger head which needs to be cut off during rolling can also be sufficiently utilized, so that the utilization ratio of raw materials is greatly increased, the pipe die manufacturing cost is reduced by about 40%, the production efficiency is high, and pipe dies with all specifications can be basically prepared by using the method.
