Superalloy fluid medium ultra-high pressure forming method and device

Abstract

The invention relates to a method and device for ultra-high-pressure forming of a superalloy fluid medium. The device includes a mold upper seat, a mold lower seat, an upper mold, a lower mold and an external filling system. The method is to inject high-pressure fluid into a pipe through a high-pressure pipe joint, A certain high-pressure environment is formed inside, and at the same time, the upper mold moves downward to bend the billet, the speed of the upper die moves down to match the internal pressure of the billet, and finally the billet is pressed into the upper and lower dies, so that the billet and the surface of the upper and lower dies are bonded , to get the final component. The wall thickness distribution of the formed part obtained by the superalloy fluid medium ultra-high pressure forming method is uniform, the surface quality is good, and the forming precision is high. The high-precision, high-efficiency, and low-cost forming of high-temperature alloy components has been realized, and the application field of fluid-filled forming has been greatly expanded, with extremely broad application prospects.
