Abstract

The invention discloses a step-type blade double-circuit nesting electrolytic processing device and method. The combined electrode part includes an upper cavity electrode and a lower cavity electrode, and the upper cavity electrode and the lower cavity electrode are fixed and electrically insulated. Connection; the switch includes a base on which the first negative plate and the second negative plate are fixedly installed and used to drive the lead rod to reciprocate between the first negative plate and the second negative plate to alternately contact the first negative plate and the second negative plate. The driving mechanism of the two negative plates, the second negative plate is electrically connected to the electrode of the upper cavity, the first negative plate is connected to the electrode of the lower cavity, the lead rod is electrically connected to the terminal block, and the terminal plate is electrically connected to the negative electrode of the power supply. With a single combined electrode, under the dual-circuit processing mode, the upper and lower blade shape processing of the blade can be completed at one time, which reduces the clamping process, reduces the repetition error, improves the processing efficiency, and makes the blade processing in pulse dynamics, effectively Helps to form a passivation touch between processing, reduce stray corrosion on the processing surface, and improve surface quality.

Description

technical field [0001] The invention relates to a special processing technology, in particular to a step-type blade double-circuit nesting electrolytic processing device and method. Background technique [0002] The blade is one of the most numerous parts in an aero-engine, and the process performance of its manufacturing technology has an important impact on the overall machining efficiency, machining cost, reliability and life of the engine. At present, the manufacturing technologies for blade parts mainly include: CNC machining, EDM, and electrolytic machining. Because the engine blade has the characteristics of thin blade shape and difficult material processing, the cost of CNC machining is high and it is easy to deform. EDM relies on thermal energy to remove materials, and there are defects such as recast layers and microcracks on the surface of machined parts, which are difficult to meet the surface quality requirements of aviation military products. However, electro...
