U shaped wire electrode electrolysis and milling method

Abstract

The invention discloses a U shaped wire electrode electrolysis and milling method. A U shaped wire electrode comprises an electrode body, wherein the electrode body takes a U shaped structure; the U shaped structure comprises two vertical sides and one bottom side connected together; during the electrolysis and milling process, an electrolytic machining device comprises a control module, a drivingmodule, a power supply and a U shaped wire electrode; the U shaped wire electrode is connected with the cathode of a machining power supply; a workpiece is connected with the anode of the machining power supply; the to-be-machined area of the workpiece is soaked in electrolyte of an electrolytic cell; during the machining process, the U shaped wire electrode and the workpiece move relatively, andwhen the U shaped wire electrode and the workpiece are opposite, the workpiece has anode electrochemical dissolution to cut off the material. The U shaped wire electrode is compact in structure and convenient and fast to mount; electrolyte flowing is better, electrolysate is thoroughly discharged, the processing efficiency is high, and adjustment of the electrode is simpler and more convenient.

Description

technical field [0001] The invention relates to the technical field of electrolytic machining, in particular to a method for electrolytic milling of U-shaped wire electrodes. Background technique [0002] Electrolytic machining has the principle of ion removal of materials, which shows that electrolytic machining technology has important development potential and application prospects in the field of micro-manufacturing. The micro-electrolytic milling processing technology uses the principle of anodic dissolution of metals in the electrolyte, uses micron-scale columnar electrodes, and combines multi-axis numerical control movements to remove metal materials at the ion level, and can process two-dimensional complex shapes and three-dimensional structures. Its processing principle is as Figure 5 shown. [0003] For electrolytic machining of complex structures and three-dimensional cavities with higher aspect ratios, electrolytic milling can be performed in multiple layers. ...
