Flexible cluster electrode jet electrolytic machining method and device

Abstract

The invention discloses a flexible bunching cluster electrode jet flow electrolytic machining method. The method comprises the steps that a tool electrode is connected with a negative pole of a power source, a workpiece is connected with a positive pole of the power source, and flexible electrode wires of the tool electrode extend out of an electric jet flow nozzle; low-voltage high speed electrolyte enters an upper portion electrolyte cavity inside the electric jet flow nozzle through an electrolyte supplying pipe, then flows through a splitter plate in the electric jet flow nozzle, is distributed to electrolyte outlets in all the flexible electrode wires, flows out of the electrolyte outlets at the high speed and is involved in an electrochemical reaction occurring between the tool electrode and the workpiece, and the flexible electrode wires are straightened under the action of the friction force of the low-voltage electrolyte flowing out at the high speed; and a machine tool spindle drives the electric jet flow nozzle and the flexible electrode wires to feed toward the workpiece, certain machining clearance is maintained between the workpiece and the flexible electrode wires on the tool electrode, and the low-voltage electrolyte flowing out at the high speed is jetted to the workpiece, so that the required machining morphology is obtained. By means of the flexible bunching cluster electrode jet flow electrolytic machining method and device, locality, stability, precision and efficiency of jet flow electrolytic machining are improved.

Description

technical field [0001] The invention belongs to the field of jet electrolytic machining with low voltage and high electrolyte flow rate, and in particular relates to a method and device for jet electrolytic machining of flexible cluster electrodes. Background technique [0002] Microstructures are widely used in aviation, aerospace, automobiles, electronics, molds, chemical fibers and other fields to improve product performance. The electrolytic machining method and the electrojet method are proven to be able to process these microstructures. The electrojet method is based on applying a high voltage (generally 100V-1000V) between the cathode and the anode, and the electrolyte is pressed into the capillary nozzle by a high-pressure diaphragm pump. , a method in which the charged and formed "cathodeized" electro-liquid beam is shot at the anode workpiece at high speed, so that the part of the material sprayed by the electrolyte solution on the workpiece undergoes anodic dissol...
