Electrolytic machining device for self-guiding bent straight hole and processing method thereof

Abstract

The invention relates to an electrolytic machining device for a self-guiding bent straight hole and a processing method thereof. The electrolytic machining device structurally and mainly comprises a flexible knife handle and an electrode, wherein the electrode is of a blocky shape and is provided with an upper end plane and a lower end plane, and the sides of the electrodes are circular arc transition surfaces; the middle part of the flexible knife handle is connected with a liquid feeding pipe in a sliding and insertion way, and the liquid feeding pipe is communicated with a through hole in the middle of the electrode; a pair of movable control bars and a pair of steering control bars are connected at the two sides of the flexible handle in the flexible knife handle in a sliding and inserting way, the movable control bars are conductors with electrified electrodes, the respective ends of the two movable control bars are respectively hinged to the centers of the circles of the circular arc transition surfaces, and hinged axes are parallel to each other; the respective certain ends of the steering control bars are connected with arc-shaped steering control blocks, and the circular arc ends of the two steering control blocks are respectively propped against the circular arc transition surfaces at the two sides of the electrode. When a hole is formed, the straight hole or bent hole processing can be realized dependent on the synchronous or asynchronous feeding of the movable control bars and the steering control bars at the two sides of the flexible knife handle; furthermore, the electrolytic machining device is more convenient to process, easy to control the processing precision, and better in hole processing quality.

Description

Technical field [0001] The invention relates to hole processing, and is a self-guided electrochemical processing device for bent straight holes and a processing method thereof. Background technique [0002] Electrochemical machining is based on the principle of anode dissolution in the electrolysis process and with the help of a shaped cathode, a process method that shapes the workpiece according to a certain shape and size. Because electrochemical machining can process almost all conductive materials, and is not restricted by the strength, hardness, toughness and other mechanical and physical properties of the material, and the metallographic structure of the material after processing basically does not change, it is widely used in machining hard Difficult-to-process materials such as high-quality alloys, high-temperature alloys, hardened steel, and stainless steel For example, the application publication number CN103781581A published in the Chinese Patent Literature, the appli...
