Embodiment 1

[0035] Such as figure 1 , Figure 4 As shown, a process method for preparing an aero-engine swirler using a special processing technology includes the step of preparing a swirler blank, the swirler blank is made of a cylindrical forging, and also includes the steps of preparing a swirler semi-finished product and The clamp repair step, the step of preparing the semi-finished product of the cyclone is: turning the blank of the cyclone and EDM in sequence to obtain the semi-finished product of the cyclone, and the step of clamp repair is: trimming the cyclone according to the requirements of the finished cyclone The semi-finished product of the cyclone is made into the finished product of the cyclone.

[0036] In this embodiment, a special processing technology is used to prepare the process method of the aero-engine swirler. By using a columnar forging as a raw material, the forging includes a forging and a forged bar. Since the metal structure of the forging is more Compared...

Embodiment 2

[0042] Such as figure 1 , Figure 4 As shown, in this embodiment, a process method for preparing an aeroengine cyclone using a special processing technology, the process flow is the same as that of Example 1, the difference is that the inspection step is: install the finished cyclone into the test aircraft Tests performed on the engine.

[0043] A kind of process method of using forged parts to prepare aeroengine swirler in this embodiment adopts the method of directly installing the finished swirler finished product on the test aeroengine for actual detection, which is beneficial to measure the mass production on the one hand. Information parameters such as strength, toughness, and durable life of the finished cyclone. On the other hand, the processing technology of the finished cyclone can also be optimized according to the measured information parameters, so that the improved parameters obtained can be applied to the aviation field. In the development and processing of ot...

Embodiment 3

[0045] Such as figure 1 , Figure 4As shown, in this embodiment, a process method for preparing an aero-engine cyclone using a special processing technology, the process flow is the same as that of embodiment 1, the difference is that the clamping step specifically includes the following steps: step a: remove the remelting Layer step: remove the remelted layer on the surface of the cyclone blade after EDM; step b: grinding the arc section step: grinding and trimming the root of the cyclone blade to form an arc surface at the root of the cyclone blade; step c: cleaning Steps: Clean the finished cyclone with alcohol to remove impurities on the surface of the finished cyclone. The clamp repairing step further processes the surface quality of the cyclone semi-finished product according to the electric discharge machining method, improves the surface quality of the finished cyclone blade, further improves the service life of the obtained cyclone, and makes the obtained The finish...

Abstract

The invention relates to the field of aero-engines and gas turbines, and particularly relates to a technical method for manufacturing an aero-engine cyclone through a special processing technology. The method comprises the step of manufacturing a cyclone blank, wherein the cyclone bank is manufactured through a cylindrical forging piece. The method further comprises the step of manufacturing semi-finished cyclone and the step of finishing through pincers; the step of manufacturing the semi-finished cyclone is that the cyclone blank is sequentially subjected to turning processing and electric spark processing to obtain the semi-finished cyclone; the step of finishing through the pincers is that the semi-finished cyclone is finished based on the requirement on a finished cyclone so as to obtain the finished cyclone. According to the method, the forging piece is outstanding in mechanical property, and two processing modes are provided, so that the manufactured cyclone product is high in strength and toughness; the yield is increased; and the processing cost and the processing period are reduced; the manufactured cyclone product can stably run for a long time in an aero-engine combustion chamber; and the service life of the aero-engine combustion chamber cannot be influenced by the quality of the cyclone.

Description

technical field [0001] The invention relates to the fields of aeroengines and gas turbines, in particular to a process for preparing aeroengine swirlers using special processing technology. Background technique [0002] The swirler is one of the very important parts in the engine. Its function is to form the recirculation zone at the head of the flame tube, reduce the airflow velocity, form a stable fire source at the head of the flame tube, and ensure the stable operation of the combustion chamber. It is often used in aero-engines The blade swirler in the annular combustion chamber generally includes a cylinder and a number of blades spirally arranged on the cylinder, and a swirl groove is formed between two adjacent blades. Since the surface of the swirler blades is mostly a complex surface, With different curvatures, it is difficult to cut directly. [0003] At present, the vane swirlers of engines in the aviation field are generally produced by single-piece precision ca...
