Abstract

The invention provides a forming cathode for forming and processing a radial diffuser blade interflow channel. The forming cathode comprises a throat channel working section which is arranged at one end of the forming cathode and is used for processing a throat region of the blade interflow channel, a diffusion working section which is arranged in the middle of the forming cathode and is used forprocessing a diffusion region of the blade interflow channel, and a forming cathode mounting handle which is arranged at the other end of the forming cathode and is used for installing the forming cathode, the end part of the throat working section is provided with a flow guide end used for guiding electrolyte to flow. When a vibrating device drives the forming cathode to feed, the a throat area of the blade interflow channel can be firstly processed by utilizing the throat working section, and then the forming cathode continues feeding, and the diffusion region of the blade interflow channelcan be processed by utilizing the diffusion working section. The flow guide end can guide the electrolyte in the machining gap to flow out of the outlet of a channel uniformly, and the flow field disorder at the outlet of the channel is effectively avoided. According to the forming cathode for forming and processing radial diffuser blade interflow channel, the channel is subjected to electrolyticmachining, and a blade interflow channel can be obtained.

Description

technical field [0001] The invention relates to the technical field of radial diffuser interblade flow channel processing, in particular to a shaped cathode used for forming the radial diffuser interblade flow channel. Background technique [0002] Such as figure 1 As shown, the main structural features of the radial diffuser 1 are as follows: along the circumferential direction of the radial diffuser 1, a plurality of interblade channels 4 are evenly distributed, and the interblade channels 4 are used as air channels for radial expansion. Compressor 1 intake and diffuser. Such as figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 As shown, the interblade flow passage 4 is narrow and shaped as a deep cavity, including a throat region 41 for intake air and a diffuser region 42 for diffusion. [0003] The material of the radial diffuser 1 is GH4169, which is a difficult-to-cut material. The profile of the interblade flow channel 4 is complex and requires high ma...
