Embodiment 1

[0037] Such as figure 1 , Figure 4 As shown, a process method for efficiently processing the swirler of an aero-engine includes the step of preparing a swirler blank, the swirler blank is made of a columnar forging, and the forging includes a forging and a forged bar , the columnar forging is made of aviation materials, and also includes a step of preparing a semi-finished product of the cyclone and a trimming step, and the step of preparing the semi-finished product of the cyclone is to subject the blank of the cyclone to at least one turning process and at least one milling process , to obtain a cyclone semi-finished product, the clamping step is to trim the outer profile of the cyclone semi-finished product according to the requirements of the aero-engine cyclone finished product, so as to obtain the cyclone finished product.

[0038] In this embodiment, a high-efficiency processing method for aero-engine swirlers uses columnar forgings as raw materials. Since the metal s...

Embodiment 2

[0047] Such as figure 1 , Figure 4 As shown, a high-efficiency processing method of the aero-engine swirler of this embodiment is the same as the process of embodiment 1, the difference is that the inspection step is a test of installing the finished swirler on the test aero-engine detection.

[0048] A kind of high-efficiency processing method of aero-engine swirler in this embodiment adopts the method of directly installing the finished swirler finished product on the test aero-engine for actual detection, on the one hand, it is beneficial to measure the mass-produced swirler Information parameters such as strength, toughness, and durable life of the finished product. On the other hand, the processing technology of the finished cyclone can also be improved according to the measured information parameters, so that the improved parameters obtained can be applied to other parts in the aviation field. In the development and processing of the aviation field, the processing of ...

Embodiment 3

[0050] Such asfigure 1 , Figure 4 As shown, a kind of high-efficiency processing method of the aero-engine swirler of this embodiment is the same as the process of embodiment 1, the difference is that the clamp repair step includes the step of grinding the swirl groove, and the grinding swirl groove The step is to grind and trim the root of the swirler blade, and form an arc-shaped surface for controlling the direction of the airflow at the root of the swirler blade.

[0051] A kind of high-efficiency processing method of the aero-engine swirler of this embodiment, grinding and trimming the root of the swirler blade, forming an arc-shaped surface for controlling the airflow direction at the root of the swirler blade, increasing the strength of the swirler blade root , improve the service life of the finished cyclone, and at the same time, when the finished cyclone rotates during use, the airflow flows along the arc surface and rotates with the cyclone to form a spiral conveye...

Abstract

The invention relates to the field of aeroengines and gasoline turbines, in particular to a technological method of a high-efficient machining swirler for an aeroengine. The method comprises a step ofpreparing a swirler blank, wherein the swirler blank is manufactured by columnar forging pieces, and the columnar forging pieces are manufactured by aviation materials; the method also comprises a step of preparing a swirler semi-finished product and a step of gripping and repairing; the step of preparing a swirler semi-finished product comprises the following steps: turning the swirler semi-finished product at least one time and milling the swirler semi-finished product at least one time so as to prepare the swirler semi-finished product; and the step of gripping and repairing comprises thefollowing steps: trimming a profile surface of the swirler semi-finished product according to a finished product requirement of the aeroengine so as to prepare a swirler finished product. By adoptinga matched machining way of turning and milling, a machining period is shortened; and by matching with a gripping and repairing operation, a finished product ratio is increased, so that the manufactured swirler finished product has the advantages of stable metal quality and longer service life, and the manufactured swirler finished product meets a high-standard requirement on the aeroengine.

Description

technical field [0001] The invention relates to the fields of aero-engines and gas turbines, in particular to a process for efficiently processing aero-engine swirlers. 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 casting and machining. ...
