High-efficiency electrolytic grinding device and processing method for honeycomb segment

Abstract

A honeycomb segment high-efficiency electrolytic grinding device and processing method, belonging to the field of special processing technology, including a workbench, a power supply, a honeycomb segment and a tool grinding wheel, the device has a novel structure, and the principle of the processing method is clear, which is different from the traditional processing of the honeycomb segment Compared with other methods, the present invention avoids defects such as tool loss, deformation of the honeycomb ring, and surface recasting layer caused by other processing methods; the present invention adopts the method of cutting the large-diameter tool grinding wheel from the side of the honeycomb sector, and through the internal spray tool The grinding wheel directly sprays the working fluid on the processing surface of the honeycomb segment, which greatly increases the removal efficiency of the honeycomb material; the inner spray liquid of the present invention can conduct the conductive forming grinding wheel, realize the efficient and precise machining of the honeycomb parts, and reduce the processing time of the honeycomb parts. Performance requirements for machine tool equipment; the feeding direction of the tool grinding wheel in the present invention is perpendicular to the direction of the honeycomb holes of the honeycomb belt, which avoids the phenomenon that the processed products block the honeycomb holes and simplifies the cleaning process after processing.

Description

technical field [0001] The invention belongs to the technical field of special processing, and relates to an electrolytic grinding device and a processing method, in particular to a high-efficiency electrolytic grinding device and a processing method of a honeycomb segment. Background technique [0002] The honeycomb air seal is an advanced technological structure for achieving a tight seal between the turbine rotor blades and the stator in modern aero-engines. The air seal is usually a metal honeycomb belt with a regular hexagonal honeycomb shape. Compared with the traditional sealing structure, the honeycomb seal greatly increases the resistance to air leakage, thereby greatly improving the working efficiency of the unit. [0003] In aero-engines, there are many kinds of honeycomb sealing structures. Generally, the honeycomb sealing structure used for inner ring sealing is often designed as an integral form, while the honeycomb sealing structure used for outer ring sealing...
