Active control type electrolysing solution flowing method in blade process and electrolysing solution circulating system

Abstract

The invention relates to an active-control electrolyte flowing method and an electrolyte circulating system in blade processing, and belongs to the field of electrolytic processing technology. The method is characterized in that (1) an entire blade processing region is divided into a blade concave processing region and a blade convex processing region by a blade; and (2) an active shunting method is adopted to divide the channel into two independent channels including an electrolyte channel for blade concave processing and an electrolyte channel for blade convex processing. The electrolyte circulating system is characterized in that four channels are arranged at the periphery inside a tool fixture (9), extending from the edges to the processing regions, and each channel is respectively connected with a flow rate control pipe. The system is also provided with an electrolyte reversing valve (20) to reverse the flowing direction of the electrolyte. The active-control electrolyte flowing method can achieve more stabile flow field for processing the blade, more uniform flow field state for processing different sections of the blade, and better processing accuracy and surface quality.

Problems solved by technology

[0013] The purpose of the present invention is to meet the needs of blade electrolytic machining technology, overcome the uneven flow of electrolyte in blade electrolytic machining, the impact of a large amount of liquid on the blank causes the flow field in the processing area to be disordered, the blank vibrates, and the flow through the blade basin and blade back cannot be actively controlled , the flow direction cannot be changed, and the adaptability and flexibility are weak. With the goal of improving the machining accuracy and surface quality of the blade, it is possible to provide a method that can accurately control the flow of the blade pot and the blade back, and the state of the flow field is stable and uniform. Actively controlled electrolyte flow method and electrolyte circulation system in more extensive blade machining
