Electrolytic machining device for special-shaped thin-walled curved surface parts

Abstract

The invention relates to an electrolytic machining device for special-shaped thin-walled curved surface parts. In the processing method of special-shaped thin-walled curved surface, there is stress inside the workpiece, which is easy to cause deformation of the part. The top surface of the clamp base of the present invention is provided with a processing surface of the processing parts, and the cathode, the cathode connecting plate and the cathode connecting rod are arranged above the processing surface of the processing parts; the guide plate is arranged above the clamp base; The processing area of ​​plates and processed parts; one side of the processing area is provided with multiple horizontal liquid inlet holes, which flow into the liquid collection chamber and flow into multiple liquid distribution holes evenly, and the outlet enters the processing area downwards; the other side is provided with upward guides. Launder, divided into a plurality of horizontal orifices. The invention is based on the electrolytic processing method, adopts a forming cathode electrolytic processing device, completes the curved surface forming processing through the feeding movement processing of the cathode, the electrolyte distribution in the processing gap is more uniform, the technical flexibility is good, the surface quality is good, and the production efficiency is high. High precision processing.

Description

technical field [0001] The invention belongs to the technical field of processing special-shaped thin-walled curved surface parts, and in particular relates to an electrolytic processing device for special-shaped thin-walled curved surface parts. Background technique [0002] With the advancement of aviation technology, a large number of various special-shaped thin-walled structural parts are used in the new aerospace industry, which greatly reduces the number of parts and weight, and makes the thrust-to-weight ratio, life, and safety of aero-engines and aerospace equipment. It has been greatly improved, but most of these parts work under the conditions of high temperature, high pressure and high speed, and stainless steel, alloy steel, heat-resistant alloy and other difficult-to-machine materials are used. At present, there are various traditional processing methods for complex special-shaped thin-walled surfaces, such as five-coordinate CNC milling, precision casting, EDM...
