Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] This embodiment provides an electrode for honeycomb processing and a method for preparing a whole honeycomb for sealing by using the electrode, so that the scheme of integrally processing a honeycomb sealing structure by an electric discharge forming machine is realized.

[0022] The electrode is a split structure, including: clamping handle 1, main electrode 2 and locking piece 3, such as figure 1 shown. The clamping handle 1 is a rod-shaped structure made of stainless steel, which can solve the problem of insufficient rigidity of the split electrode. The bottom of the clamping handle 1 protrudes through the mounting holes on the upper and lower end surfaces of the main motor 2 and is locked by the locking member 3 . In order to eliminate the positioning gap, the matching surface of the clamping handle 1 and the mounting hole on the main motor 2 ...

Abstract

The invention discloses an electrode for honeycomb machining and a manufacturing method for an integral honeycomb. The scheme of adopting an electric spark forming machine and connecting the electric spark forming machine to the annular inner wall of a product to integrally machine a honeycomb sealing structure can be achieved. The electrode is a split electrode and comprises a clamping handle, a main electrode body and a locking part. The bottom of the clamping handle stretches out of an installation hole in the main electrode body and then is locked through the locking part. A positioning face is designed on the main electrode body, so that it is ensured that the electrode is directly used for aligning a workpiece during machining. By means of the electrode, the honeycomb sealing structure can be directly and integrally machined on the annular inner wall of the product in an electric spark machining manner, and honeycomb machining of a whole inner section can be completed after one-time clamping.

Description

technical field [0001] The invention relates to an electrode and a honeycomb preparation method using the electrode. Background technique [0002] Aircraft engines are often sealed with structures such as honeycomb, and the efficiency of the turbine is improved by reducing the gap between the turbine rotor blades and the stator when they are working. In terms of the preparation means of the honeycomb structure, it can be realized by means of integral preparation and split processing. At present, the honeycomb structure commonly used in domestic aero-engines is to process the honeycomb ring first, and then weld it by brazing. It can also be integrally cast in the product casting stage. [0003] However, when the working temperature is high, there is a hidden danger of desoldering in the method of split brazing honeycomb; while the process method of integrally casting honeycomb on the inner wall of the product is more difficult and costly for precision casting of ultra-thin s...
