Abstract

The invention discloses a blade machining process. The process dispersion principle is fully adopted; by utilizing a common plane abrasion device, the cost of the device is reduced and, flow line production can be carried out on a production site in batches; meanwhile, a low-melting-point alloy precise positioning mode is adopted, the machining benchmark is converted, a space positioning point isconverted into a plane, so that the machining process is reliable and stable, the production efficiency is improved, the machining quality is guaranteed, large-batch turbine guide blade production canbe met, and the process can be widely applied to machining of aero-engines and turbine guide blades of gas turbines.

Description

technical field [0001] The invention belongs to the technical field of aero-engine machinery, and in particular relates to a blade processing technology. Background technique [0002] The turbine guide vane is located in the part of the aero-engine with the highest temperature, the most complex stress and the harshest environment, and is known as the "jewel in the crown". The exterior structure is composed of the blade body and the edge plate, and the inner cavity is hollow, and the surface of the blade body is covered with air film holes. It is complex in shape, demanding and difficult to process. The main materials are DZ40M, IC10, DD5, DD6, etc. At present, the turbine guide vanes are generally welded by single-joint blades to form double-joint blades. The single blade is precisely cast without margin, and the inner and outer edge plate wedge surfaces and end faces are machined. Establish a machining benchmark for the subsequent precision machining of double-connected ...
