Summary: | The invention discloses a solid rocket engine jet pipe blanking cap forming method. The method comprises the steps that a spinning core mold and a spinning roller are manufactured; the aluminum alloy plate is cut into a circular spinning blank, homogenizing annealing treatment is conducted, and the spinning blank is obtained; a spinning core mold is installed on a spinning machine, and the spinning core mold is heated to 200-230 DEG C; the spinning blank is installed on a spinning core mold and tightly jacked by a tail top, and the spinning blank is heated to 300-350 DEG C; by means of two spinning rollers and a strong spinning and multi-cycle common spinning process, the spray pipe blanking cap is subjected to spinning forming on a numerical control spinning machine through multi-pass spinning machining, and a spinning part semi-finished product is obtained; the tail top is withdrawn, and the blanking cap spinning part is dismounted; carrying out low-temperature annealing treatment on the blanking cap spinni |
