Abstract

The invention discloses a method for solving the deformation of the machining process of a low-pressure turbine disc, which includes the step line control of the turning process, the clamping control in the broaching process, the process control in the shot blasting process, and other processes to carry out the finishing turning process, and the finishing turning is completed Finally, leave a margin of 0.2mm for the benchmark and related matching surfaces. After broaching, repair the side of the tongue and groove and the roundness of the disc center as a follow-up benchmark. After milling, repair the inner and outer sides of the deformed part of the installation edge. After shot peening The final finishing of the assembly surface and the assembly hole is in place, which effectively avoids the technical problem of deformation of the low-pressure turbine disk during processing.

Description

technical field [0001] The invention relates to the technical field of low-pressure turbine disk machining technology for new materials of aero-engines, in particular to a method for solving the deformation of the low-pressure turbine disk during machining. Background technique [0002] The turbine disk is the most critical core rotating part in the aero-engine. Its working conditions are harsh, and it needs to withstand the double superposition of high temperature and high pressure. The manufacturing process is complex and the technical requirements are high. It has long been one of the problems restricting the development of aero-engines in my country; At present, the low-pressure turbine disk is a large-diameter, thin-walled and easily deformed part, which is easily deformed by factors such as improper clamping force, uneven cutting force, high-speed broaching and shot peening during processing. Contents of the invention [0003] The technical problem to be solved by the...
