Abstract

The invention provides a radial diffuser channel pretreatment method. The method comprises the following steps that S21, an electrolytic machining environment is prepared; S22, a through-hole cathodeis used for carrying out vibration feeding electrolytic machining on a channel of a radial diffuser at the feeding speed of 5mm / min-6mm / min, and the channel is broken through by using a burr working section of the through-hole cathode; and S23, the through-hole cathode is used for carrying out vibration feeding electrolytic machining on the channel of at the feeding speed of 3mm / min-4mm / min, uneven allowance on the inner wall of the channel is eliminated by using an inner wall working section of the through-hole cathode. Burrs can be eliminated through the burr working section of the through-hole cathode to break through the channel, the problem that a short circuit is generated by contact between a forming cathode and burrs when the forming cathode carries out vibration feeding electrolytic machining on the channel is avoided, the uneven allowance on the inner wall of the channel can be eliminated by using the inner wall working section of the through-hole cathode, and the problem that a short circuit is generated by contact between a forming cathode and the inner wall of the channel when the forming cathode carries out vibration feeding electrolytic machining on the channel is avoided.

Description

technical field [0001] The invention relates to the technical field of radial diffuser interblade flow channel processing, in particular to a radial diffuser channel pretreatment method. Background technique [0002] like 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. like figure 2 , image 3 , Figure 4 , Figure 5 and Image 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 machining accuracy. Traditional machining...
