High-temperature alloy fluid medium ultrahigh-pressure forming method and device

Abstract

The invention relates to a high-temperature alloy fluid medium ultrahigh-pressure forming method and device. The device comprises an upper mold base, a lower mold base, an upper mold, a lower mold and an external flow filling system. The method comprises the steps that high-pressure fluid is injected into a pipe through a high-pressure pipe connector, a certain high-pressure environment is formed in the pipe, meanwhile, the upper mold moves downwards to bend a blank, the descending speed of the upper mold is matched with the internal pressure of the blank, finally, the blank is pressed into the upper mold and the lower mold, the blank is attached to the surfaces of the upper mold and the lower mold, and a final component is obtained. The formed component obtained through the high-temperature alloy fluid medium ultrahigh-pressure forming method is uniform in wall thickness distribution, good in surface quality and high in forming precision. High-precision, high-efficiency and low-cost forming of the high-temperature alloy component is achieved, the application field of fluid filling forming is greatly widened, and extremely wide application prospects are achieved.
