Abstract

An electrolysis-broaching compound processing tool electrode belongs to the technical field of special processing. The invention has a novel structure, and realizes pulling the blade and The porous metal electrode is insulated to ensure that the electrochemical machining process and the mechanical broaching process do not interfere with each other; the porous metal material is used as the electrochemical machining electrode material, which not only avoids external spraying, but when the tool cuts into the workpiece, the electrochemical machining process supplies Insufficient liquid, and avoids the problem of uneven corrosion of the surface material of the workpiece during internal spraying; the broaching blade and porous material electrode in the present invention are designed to be separated and disassembled, and the broaching blade and the porous material electrode can be quickly replaced when processing parts with different contour shapes. Porous material electrodes have achieved the advantages of good applicability and low overall cost.

Description

technical field

[0001] The invention belongs to the technical field of special processing, and relates to a tool electrode, in particular to an electrolysis-broaching composite processing tool electrode. Background technique

[0002] The broach is a special tool for broaching. It is a tool with multiple rows of teeth. Its processing principle is to use the different tooth lifts of each tooth to remove material in turn. According to the different processing objects, it can be divided into round broach and keyway. Broaches, involute broaches, etc. Broaching is usually carried out under low-speed and heavy-load conditions. The extrusion friction between the broach flank and the workpiece processing surface is severe, and the broaching load is huge, which is prone to processing defects such as extrusion spots, ring ripples, and scratches. In addition, due to the influence of the contour characteristics of the processed surface, intermittent contact of multiple teeth and other n...
