The device has the characteristics of low cost, high efficiency and strong versatility.

Description

Integral impeller multi-channel electrolytic machining device technical field The multi-channel electrolytic machining device for an integral impeller of the invention belongs to the technical field of electrolytic machining. Background technique The integral impeller is one of the important parts in rocket engines, aero-engines and aviation airborne equipment. The machining accuracy, machining quality and machining efficiency of the integral impeller have an important impact on the performance, quality and cost of the product. Before machining the blade profile of the integral impeller to the design requirements, the machining of the interblade channel of the integral impeller is an indispensable process. At present, the machining methods of interblade channels of integral impellers include machining, electric discharge machining, electrolytic machining, etc. Among them, machining has great limitations. Most of the blade materials of modern aviation and aerospace engines...

Problems solved by technology

Neither of these two patents proposes multi-electrode simultaneous processing, and the efficiency cannot be greatly improved

At present, the processing efficiency of a single electrode has no room for significant improvement. In addition, for many integral impellers, the existing electrolytic processing devices are not universal and cannot achieve small and uniform processing allowances. Therefore, reasonable design and processing It is of great significance to increase the number of cathodes and improve the processing efficiency of the overall impeller
