Abstract

The invention discloses a precise forming method of a high-temperature alloy mounting seat, comprising the main process route as follows: blank preparing, pre-forging, pre-forming, forming, carrying out solution heat treatment and cold straightening, wherein the blank preparing process comprises the following steps of: feeding, stretching, clearing the surface, cutting, clearing the surfaces, carrying out loose tooling forging and marking; and the die forging process comprises the following steps of: clearing the surface to remove an oxide layer and surface defects, grouping thicknesses, coating glass lubricant, pre-forging three times, pre-forming three times, removing burrs, clearing the surface, coating the glass lubricant, carrying out solution heat treatment on a forging at 1150 DEG C, and cold straightening. The precise forming method has the advantages that the whole process of parts is reasonable; the remarkable advantages of short process, small machining workload and short manufacturing period are achieved; the complex thin-wall curved surface of the forging is directly forged without residue in the forging process to ensure that the material consumption is reduced; the bottom of the forging is not needed to be machined to ensure that a metal flow line is almost not damaged so that the service performance of the parts is in a more ideal state; and the process is advanced and has wide market prospect.
