Description

technical field [0001] The invention relates to an electrolytic machining device, in particular to a multi-taper inner hole electrolytic machining device. Background technique [0002] In the antiaircraft artillery used for artificial rainfall enhancement, the multi-taper inner hole charge chamber is an inevitable constituent element of the antiaircraft artillery ammunition launch. For example, some processing objects not only have many conical surfaces, high surface roughness, particularly deep inner hole, large aspect ratio, but also high requirements for the size and position accuracy of each conical surface, and the hardness and strength are further increased after heat treatment. , which brings great difficulty to processing and manufacturing. Using conventional processing methods, it is very difficult to process quenched components, which not only has low efficiency, large energy consumption, but also high cost. The current processing methods mainly include: [0003...

AI Technical Summary

Problems solved by technology

[0003] ① CNC boring and turning processing, the tool bar is longer during CNC turning, prone to vibration, poor surface roughness, low efficiency, high cost, surface quality and position accuracy can not meet the requirements

[0004] ② Forming reaming processing, the cutting area is large, the tool cost is high, the processing quality is restricted by the hardness of the material, it is difficult to process materials with high hardness, especially for parts after quenching

[0005] ③Electric pulse processing, due to the loss of tools in the processing process, the processing process is unstable and the processing process cannot be controlled

[0008] (1) The flow field distribution and margin matching ratio of the cathode are not easy to optimize, and the trial production cycle is long in the early stage of design;

[0009] (2) It is difficult to control the balance gap in the processing process, and it is difficult to achieve the best effect;

[0010] (3) The structure of the cathode is complex and difficult to process
